  • Forthcoming The motivated memory of noise Article dans une revue:

    We propose a two-stage experiment in which people receive feedback about their relative intelligence. This feedback is a noisy message reminded at every stage, so that subjects cannot forget this ego-relevant information. Instead, we exogenously vary whether the informativeness of the message is reminded in the second stage. We investigate how this treatment variation affects the informativeness reported by subjects, and their posterior beliefs about their intelligence. We show that subjects report informativeness in a self-serving way: subjects with negative messages report that these messages are significantly less informative in the absence of reminder than with it. We also show that the lack of reminder about message informativeness allows subjects to keep a better image of themselves. These results are confirmed by complementary treatments in which we decrease messages informativeness: subjects tend to inflate the informativeness of positive messages that should now be interpreted as bad news.

  • Données brutes d’observation des Conférences citoyennes régionales du Grand débat national Rapport:

    Dix-huit Conférences citoyennes régionales (CCR) (13 dans les régions métropolitaines et cinq dans les départements et régions d’outre-mer) et une Conférence citoyenne nationale dédiée à la jeunesse se sont tenues dans la deuxième phase du Grand débat national (GDN) (soit les vendredi et samedi 15-16 mars 2019, soit les vendredi et samedi 22-23 mars 2019). 1 404 personnes y ont participé (1 216 dans les 13 CCR hexagonales, 68 dans la Conférence nationale sur la jeunesse, à partir d’un tirage au sort national dans la base des numéros de téléphones, et 120 dans les cinq CCR des départements et régions d’outre-mer, à partir d’un recrutement spécifique à chacun de ces territoires). Pour la France métropolitaine, il s’agit du plus vaste tirage au sort réalisé pour constituer un mini-public. Ce rapport décrit en premier lieu précisément le processus de recrutement, globalement désigné par les termes de tirage au sort, pour discuter la représentativité des CCR. Puis il décrit le protocole d’observation de leur déroulement, mis en place par l’Observatoire des débats (https://observdebats.hypotheses.org/), ainsi que le processus de passation des questionnaires lors des CCR, d’une part (en entrée et en sortie) par la mission organisatrice, d’autre part (en sortie) par les chercheurs rassemblés par l’Observatoire des débats. Le rapport compare ensuite les caractéristiques socio-démographiques des participants aux CCR avec celles de la population française générale, ce qui nous permet de montrer que les CCR ne sont pas représentatives de la population générale. Finalement, le rapport resitue les réponses données aux questionnaires et les statistiques descriptives associées (c’est-à-dire le nombre de répondants à chaque question et la distribution, la moyenne et l’écart-type des réponses).

  • Universal social welfare orderings and risk Article dans une revue:

    How can social prospects be evaluated and compared when there may be a risk on i) the actual allocations that people will receive, ii) the existence of these future people, and iii) their preferences? This paper investigates this question, which can arise when considering policies, such as climate policy, that affect people who do not yet exist. We start from the observation that there is no social ordering that meets minimal requirements of fairness, social rationality, and respect for people’s ex ante preferences. We explore three ways around this impossibility. First, if we drop the ex ante Pareto requirement, we can obtain fair ex post criteria that take an (arbitrary) expected utility of an equally-distributed equivalent level of well-being. Second, if the social ordering is not an expected utility, we can obtain fair ex ante criteria that evaluate uncertain individual prospects with a certaintyequivalent measure of well-being. Third, if we accept that interpersonal comparisons rely on VNM utility functions even in absence of risk, we can construct expected utility social orderings that satisfy of a version of Pareto ex ante.

  • Equivalence Scales Revisited: Evidence from Subjective Data Pré-publication, Document de travail:

    Equivalence scales (ES) are widely used to compare income levels across different households.

    Yet the commonly used OECD and square-root scales rely on assumptions about household economies of scale that lack robust empirical support. Using responses to the Minimum Income Question (MIQ) from the European Union Statistics on Income and Living Conditions (EU-SILC) survey, we construct subjective ES based on panel data, rather than relying on pooled OLS as in most previous studies, allowing us to track how income needs evolve within households over time instead of comparing different households. The economies of scale in this subjective scale are notably different from those in traditional ES, and these differences have a substantial effect on the levels and distribution of equivalised income. Based on our empirical findings, we propose a simple alternative to conventional ES and illustrate its implications for poverty and inequality, both within and across countries. Our results show that the choice of equivalence scale significantly influences not only the estimated levels of these variables but also country rankings in comparative analyses.

  • Is Resilience Inherited? Pré-publication, Document de travail:

    We here use European Social Survey data to disentangle the ‘inherited’ and ‘contextual’ components of resilience, following the approaches taken in Alesina and Giuliano (2010) and Luttmer and Singhal (2011). We suggest that the inherited part of resilience reflects culture in the country of birth, while the contextual part captures both institutions and culture in the country where the individual currently resides. We separately identify these two components via a sample of immigrants, for whom the birth and residence countries differ. We find that resilience is both inherited and contextual, with the latter component being the most important. The ‘inherited’ component of resilience is larger for men and those who do not have citizenship in their residence country. We last present some evidence from second-generation immigrants of the intergenerational transmission of inherited cultural resilience.

  • The Old Folks at Home: Parental Retirement and Adult Children’sWell-being Pré-publication, Document de travail:

    We here use UK data and exploit the State Pension eligibility age to establish the causal effect of parental retirement on adult children’s well-being in a Fuzzy Regression Discontinuity Design analysis. Maternal retirement increases adult children’s life and income satisfaction by 0.20 standard deviations in the short run. These impacts are stronger for adult children with lower incomes, with young children of their own, and who live close to their retired parents. We emphasise the critical role of intergenerational time transfers from retired mothers in enhancing their adult children’s well-being.

  • A Room of One’s Own. Work from Home and the Gendered Allocation of Time Pré-publication, Document de travail:

    The traditional specialization of men in paid work and women in housework is rooted in the spatial separation of these activities. We examine the possible consequences of the recent expansion of Work from Home (WfH) for the gendered allocation of time. We focus on the time devoted to housework by men and women who work from home versus at the workplace, before and after the Covid pandemic. Using data on several thousand workers drawn from the American Time Use Survey, we find that the gender gap in unpaid work has declined by about 27 minutes per day, i.e. by about 40% for remote workers. Among those, women now spend more time on paid work and less on unpaid work, whereas men do more household chores.

  • From Pink-Collar to Lab Coat: Cultural Persistence and Diffusion of Socialist Gender Norms Article dans une revue:

    We study vertical transmission and societal diffusion of gender norms using the large immigration wave from the former Soviet Union (FSU) to Israel in the early 1990’s. Tracking the educational choices of an entire cohort, born in 1988–89, we compare gender gaps among immigrants from the FSU versus natives and immigrants from other countries. We find smaller gender gaps among FSU immigrants in both traditionally male-dominated STEM fields and female-dominated pink collar jobs, e.g., education and social work. These patterns are largely driven by the behavior of FSU women and are not explained by early achievement levels or comparative advantage. Leveraging variation in the concentration of FSU immigrants across middle schools, we find that among natives, gender gaps narrow with the exposure to FSU immigrants, reflecting a shift in the choice patterns of native women towards STEM and away from pink collar fields.

  • Machine learning in the prediction of human wellbeing Article dans une revue:

    Subjective wellbeing data are increasingly used across the social sciences. Yet, despite the widespread use of such data, the predictive power of approaches commonly used to model wellbeing is only limited. In response, we here use tree-based Machine Learning (ML) algorithms to provide a better understanding of respondents’ self-reported wellbeing. We analyse representative samples of more than one million respondents from Germany, the UK, and the United States, using data from 2010 to 2018. We make three contributions. First, we show that ML algorithms can indeed yield better predictive performance than standard approaches, and establish an upper bound on the predictability of wellbeing scores with survey data. Second, we use ML to identify the key drivers of evaluative wellbeing. We show that the variables emphasised in the earlier intuition- and theory-based literature also appear in ML analyses. Third, we illustrate how ML can be used to make a judgement about functional forms, including the existence of satiation points in the effects of income and the U-shaped relationship between age and wellbeing.

  • How large is « large enough » ? Large-scale experimental investigation of the reliability of confidence measures Pré-publication, Document de travail:

    Whether individuals feel confident about their own actions, choices, or statements being correct, and how these confidence levels differ between individuals are two key primitives for countless behavioral theories and phenomena. In cognitive tasks, individual confidence is typically measured as the average of reports about choice accuracy, but how reliable is the resulting characterization of within-and between-individual confidence remains surprisingly undocumented. Here, we perform a large-scale resampling exercise in the Confidence Database to investigate the reliability of individual confidence estimates, and of comparisons across individuals’ confidence levels. Our results show that confidence estimates are more stable than their choice-accuracy counterpart, reaching a reliability plateau after roughly 50 trials, regardless of a number of task design characteristics. While constituting a reliability upper-bound for task-based confidence measures, and thereby leaving open the question of the reliability of the construct itself, these results characterize the robustness of past and future task designs.

  • Effectiveness of ex ante honesty oaths in reducing dishonesty depends on content Article dans une revue:

    Dishonest behaviours such as tax evasion impose significant societal costs. Ex ante honesty oaths—commitments to honesty before action—have been proposed as interventions to counteract dishonest behaviour, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a baseline oath)—proposed, evaluated and selected by 44 expert researchers—and a no-oath condition in a megastudy involving 21,506 UK and US participants from Prolific.com who played an incentivized tax evasion game online. Of the 21 interventions, 10 significantly improved tax compliance by 4.5 to 8.5 percentage points, with the most successful nearly halving tax evasion. Limited evidence for moderators was found. Experts and laypeople failed to predict the most effective interventions, though experts’ predictions were more accurate. In conclusion, honesty oaths were effective in curbing dishonesty, but their effectiveness varied depending on content. These findings can help design impactful interventions to curb dishonesty.

  • Anticipatory Anxiety and Wishful Thinking Article dans une revue:

    Across five experiments (N = 1,714), we test whether people engage in wishful thinking to alleviate anxiety about adverse future outcomes. Participants perform pattern recognition tasks in which some patterns may result in an electric shock or a monetary loss. Diagnostic of wishful thinking, participants are less likely to correctly identify patterns that are associated with a shock or loss. Wishful thinking is more pronounced under more ambiguous signals and only reduced by higher accuracy incentives when participants’ cognitive effort reduces ambiguity. Wishful thinking disappears in the domain of monetary gains, indicating that negative emotions are important drivers of the phenomenon.

  • Workers as Partners: a Theory of Responsible Firms in Labor Markets Pré-publication, Document de travail:

    We develop a theoretical framework analyzing responsible firms (REFs) that prioritize worker welfare alongside profits in labor markets with search frictions. At the micro level, REFs’ use of market power varies with labor conditions: they refrain from using it in slack markets but may exercise it in tight markets without harming workers. Our macro analysis shows these firms offer higher wages, creating a distinct high-wage sector. When firms endogenously choose worker bargaining power, there is a trade-off between worker surplus and employment, though this improves with elastic labor supply. While REFs cannot survive with free entry, they can coexist with profit-maximizing firms under limited competition, where their presence forces ordinary firms to raise wages.

  • Révision de la taxation des boissons sucrées en France : quelles intentions pour quels effets ? Article dans une revue:

    La taxation des boissons sucrées est, depuis 15 ans, une mesure de santé publique appliquée sur un nombre croissant de territoires. Cette intervention gagne à être évaluée, ce qui implique d’en clarifier les finalités. Basé sur les résultats d’un projet de recherche pluridisciplinaire, cet article analyse les conditions de la révision de la taxation des boissons sucrées en France en 2018. Il met en évidence que l’intention est plutôt de faire évoluer la qualité nutritionnelle de l’offre de boissons que d’influencer directement le comportement des consommateurs. Par ailleurs, il présente quelques effets associés à la mise en oeuvre de la taxe.

  • Rapport de recherche sur l’élaboration, la mise en œuvre et les effets de la taxe soda appliquée en France depuis juillet 2018 Rapport:

    Afin de promouvoir une alimentation plus favorable à la santé, l’environnement des consommateurs fait l’objet d’interventions des pouvoirs publics visant à mieux les informer, à inciter les fabricants à améliorer la composition nutritionnelle des produits, ou encore à encadrer le marketing dont ces derniers font l’objet. Depuis quelques années, la taxation d’aliments et de boissons au profil nutritionnel peu favorable à la santé fait partie des mesures qui suscitent de l’intérêt. La taxation des boissons sucrées ou « taxe soda » fait partie des mesures recommandées par l’Organisation mondiale de la santé (OMS) (WHO 2022). En France, une taxe soda 1 a été instaurée en janvier 2012. Modifiée en juillet 2018, elle est désormais indexée sur la teneur en sucres ajoutés dans la boisson (Ministère de l’action et des comptes publics 2018). A l’heure où d’autres pays s’interrogent sur la mise en place ou l’optimisation d’une telle mesure, ce changement donne l’opportunité de tirer des apprentissages de son élaboration, de sa mise en œuvre et de ses effets sur l’offre et la consommation. C’est dans cette perspective qu’a été construit le projet de recherche Soda-Tax (2019-2023), coordonné par l’Ecole des hautes études en santé publique (EHESP) en collaboration avec l’Ecole d’Economie de Paris, l’Institut National de la Recherche pour l’Agriculture, l’Alimentation et l’Environnement (INRAE), l’Université Sorbonne Paris Nord (USPN), et Nantes Université. Ce projet a été cofinancé par la Ligue Contre le Cancer dans le cadre de l’Appel à projets général de l’Institut pour la Recherche en Santé Publique (IReSP) – volet prévention et promotion de la santé 2018. Ce rapport synthétise les résultats de la recherche. Certains d’entre eux ont déjà été publiés. D’autres résultats seront soumis dans les prochains mois à des revues scientifiques dont le processus de révision par les pairs pourrait dans certains cas les amener à évoluer. Ces résultats sont donc ici communiqués à titre préliminaire, la diffusion de ce rapport ayant vocation à éclairer le pilotage de la mesure et à informer les acteurs intéressés dans un délai plus opportun.

  • Dynamically rational judgment aggregation Article dans une revue:

    Judgment-aggregation theory has always focused on the attainment of rational collective judgments. But so far, rationality has been understood in static terms: as coherence of judgments at a given time, defined as consistency, completeness, and/or deductive closure. This paper asks whether collective judgments can be dynamically rational, so that they change rationally in response to new information. Formally, a judgment aggregation rule is dynamically rational with respect to a given revision operator if, whenever all individuals revise their judgments in light of some information (a learnt proposition), then the new aggregate judgments are the old ones revised in light of this information, i.e., aggregation and revision commute. We prove an impossibility theorem: if the propositions on the agenda are non-trivially connected, no judgment aggregation rule with standard properties is dynamically rational with respect to any revision operator satisfying some basic conditions. Our theorem is the dynamic-rationality counterpart of some well-known impossibility theorems for static rationality. We also explore how dynamic rationality might be achieved by relaxing some of the conditions on the aggregation rule and/or the revision operator. Notably, premise-based aggregation rules are dynamically rational with respect to so-called premise-based revision operators.

  • Deliberation and the wisdom of crowds Article dans une revue:

    Does pre-voting group deliberation improve majority outcomes? To address this question, we develop a probabilistic model of opinion formation and deliberation. Two new jury theorems, one pre-deliberation and one post-deliberation, suggest that deliberation is beneficial. Successful deliberation mitigates three voting failures: (1) overcounting widespread evidence, (2) neglecting evidential inequality, and (3) neglecting evidential complementarity. Formal results and simulations confirm this. But we identify four systematic exceptions where deliberation reduces majority competence, always by increasing Failure 1. Our analysis recommends deliberation that is ‘participatory’, ‘neutral’, but not necessarily ‘equal’, i.e., that involves substantive sharing, privileges no evidences, but might privilege some persons.

  • Is It Possible to Raise National Happiness? Pré-publication, Document de travail:

    We revisit the Easterlin paradox about the flatness of the happiness trend over the long run, in spite of sustained economic development. With a bounded scale that explicitly refers to « the best possible life for you » and « the worst possible life for you », is it even possible to observe a rising trend in self-declared life satisfaction? We consider the possibility of rescaling, i.e. that the interpretation of the scale changes with the context in which respondents are placed. We propose a simple model of rescaling and reconstruct an index of latent happiness on the basis of retrospective reports included in unexploited archival data from the USA. We show that national well-being has substantially increased from the 1950s to the early 2000s, on par with GDP, health, education, and liberal democracy. We validate our new index on several datasets, and find that it captures important changes in personal life circumstances over and above nominal life satisfaction. Our model sheds light on several well-documented happiness puzzles, including why life satisfaction did not drop during the COVID-19 pandemic, why Ukrainians report similar levels of life satisfaction today as before the war, and why people take life-changing decisions -like having kids -that seem to make them less happy.

  • Méthodes d’évaluation des risques sanitaires et environnementaux et des enjeux socio-économiques associés aux plantes obtenues au moyen de certaines nouvelles techniques génomiques (NTG) Rapport:

    Depuis le 1er janvier 2022, conformément à l’ordonnance n° 2021-1325 du 13 octobre 2021 et au décret n° 2021-1905 du 30 décembre 2021, l’Anses reprend les missions du Haut conseil des biotechnologies (HCB) concernant l’évaluation des risques pour l’environnement de l’ensemble des utilisations de biotechnologies en milieu ouvert, et les impacts socioéconomiques. L’Anses a été saisie dans le cadre de ces nouvelles missions par la Direction générale de la prévention des risques (DGPR) et la Direction générale de l’alimentation (DGAl) sur l’utilisation des nouvelle techniques génomiques (NTG) sur les végétaux. Les autres instances ayant repris les missions du HCB, à savoir le Conseil économique, social et environnemental (CESE) et le Comité consultatif national d’éthique (CCNE), ont également été sollicité sur cette question sur les périmètres correspondant respectivement aux questions sociétales et éthiques. Par ailleurs, il convient de noter que de nombreux acteurs institutionnels publics, organisations professionnelles et syndicales ont également produit des rapports sur les NTG. Le rapport d’expertise collective est réalisé dans le périmètre des missions de l’Anses sur les biotechnologies, incluant l’évaluation des risques sanitaires et environnementaux et les impacts socio-économiques. Il vise à éclairer les demandeurs sur ce périmètre qui couvre seulement une partie des enjeux liés à l’utilisation des NTG dans le domaine de la sélection végétale. Les questions instruites dans ce rapport sont donc limitées à ce périmètre et les conclusions devront être prises en compte uniquement dans ce cadre et mises en perspective avec les avis des autres instances sollicitées. Il convient de noter que cette expertise a été engagée avant la proposition de règlement de la Commission du 5 juillet 20231. Suite à sa publication, l’Anses a décidé de s’autosaisir afin de mener une analyse des critères définissant les plantes NTG de catégorie 1, considérées comme équivalentes aux plantes conventionnelles, exposés dans l’annexe 1 et justifiés par une note technique diffusée par la Commission européenne en octobre (Anses 2023). Cette analyse a été réalisée en parallèle et ses conclusions n’ont donc pas été prises en compte dans le présent travail d’expertise, réalisé dans le cadre du périmètre défini précédemment, qui ne fait pas la distinction entre les plantes NTG de catégorie 1 et 2.

  • L’économie du « The Old Firm » : Vieille Entente ou Vieille rivalité ? Article dans une revue:

    Un des derbys les plus légendaires au monde qui repose sur une rivalité politico-religieuse concerne le match qui oppose en Écosse, à Glasgow, le Celtic au Rangers. Cependant, les premières confrontations à la fin du XIXe siècle étaient avant tout de gros succès populaires et commerciaux, d’où l’appellation The Old Firm (« La Vieille Entente »), symbolisant le commun intérêt financier des deux clubs de la capitale écossaise. Ce n’est qu’une vingtaine d’années plus tard, dans les années 1910 que l’antagonisme apparaîtra véritablement : Verts contre. Bleus, Catholiques vs. Protestants, Républicains vs. Unionistes. Même si aujourd’hui, The Old Firm a perdu quelque peu de sa superbe au niveau européen, tant du point de vue sportif qu’économique, il demeure un succès populaire qui génère d’importants revenus les jours de match. La rivalité, toujours essentielle à ce succès, a aussi changé de nature : la société étant devenue moins religieuse, The Old Firm est devenu son propre générateur de « sectarisme ».

  • How (absent) fans influenced football during the COVID 19 pandemic? Article dans une revue:

    The fact that home football teams win more games than away teams has been largely discussed in the literature. Crowd factors appear to be the most dominant cause of this home advantage . At the end of the 2019–2020 season, the COVID-19 pandemic forced European football teams to close their stadium to fans, allowing researchers to exploit this natural experiment to analyze the effects of crowd on match outcomes and referees’ decisions. To answer to this question, we used match data played in the top two divisions of four of the main national professional leagues in European countries and Portugal in the 2018–19 and the 2019–20 seasons. We find that the total absence of a generally supportive crowd has a significant effect on home advantage. This results in a reduction of the chances of a home win, a poorer performance by the home team’s players, and more severe refereeing decisions toward the home team and less severe toward the away team.

  • Preference elicitation methods and equivalent income: an overview Pré-publication, Document de travail:

    The equivalent income is a preference-based, interpersonally comparable measure of well-being.

    Although its theoretical foundations are well-established, empirical applications remain limited, primarily due to the detailed data requirements on individuals’ preferences across various wellbeing dimensions. This paper reviews the literature on preference elicitation methods with a focus on estimating equivalent income. We examine several survey-based methods, including contingent valuation, multi-attribute choice or rating experiments, and life satisfaction regressions. The review highlights the advantages and limitations of each method, emphasizing the considerable scope for methodological improvements and innovations.

  • Unequal inequality aversion within and among countries and generations Article dans une revue:

    Suppose that, for whatever reason, it is decided that inequalities within countries are more offensive than inequalities between countries, and that inequalities between populations living together are more offensive than inequalities between generations living in different times. Can a social welfare function express that preference? We show that it is actually difficult to incorporate such a localist preference into a social welfare function, except in a limited way (i.e., from a situation of specific similarity between countries). We also show that in order to obtain such preferences, the relative size of inequality aversion within and between countries may be counter-intuitive in some relevant cases, in the sense that a greater inequality aversion may happen to be required across countries than within countries. This research highlights new social welfare functions that aggregate the outcomes of evaluations over pairs of agents.

  • Un monde en guerre Ouvrages:

    Malgré les espoirs nourris par les démocraties après la Seconde Guerre mondiale, malgré la tentative de construire un ordre international fondé sur le multilatéralisme et malgré la dissuasion nucléaire, la guerre ne cesse de se rallumer en de multiples points du monde, y compris aux portes de l’Europe. Depuis 2022, la guerre en Ukraine a réactivé d’anciens débats : rationalité et justification morale de la guerre, nature des interactions stratégiques entre acteurs du conflit, mobilisation de la population civile, légitimité et efficacité des sanctions contre l’agresseur. Elle soulève également de nouvelles questions. Du côté de la Russie, la guerre fait-elle l’objet d’un consensus au sein des élites ? Pour l’Union européenne, est-elle l’occasion d’une cohésion approfondie, à l’image de l’accueil coordonné des réfugiés ukrainiens ? Ce conflit illustre également l’étendue des armes et des cibles de guerre, des plus traditionnelles telles que l’eau aux outils de communication les plus modernes. Les douze contributions réunies dans ce volume abordent ces questionnements à l’aide des outils propres à différentes disciplines des sciences sociales et humaines. La plupart se rapportent à la guerre en Ukraine, mais certaines ramènent le lecteur au Moyen Âge ou à l’Antiquité, tandis que d’autres appréhendent la manière d’écrire l’histoire de la guerre ou de la représenter dans une œuvre picturale.

  • Work from home and subjective wellbeing Chapitre d’ouvrage:

    Everyone expects telework to ‘stick’, but will this make workers happier? On the one hand, work from home (WFH) is clearly desired by a majority of workers, as evidenced by their willingness to pay for this arrangement. This finding is supported by all choice experiments, either real, on a recruitment platform for example, or hypothetical, via surveys. But, on the other hand, working entirely from home seems to be detrimental to their life satisfaction and their mental health, as shown by difference-in-differences studies based on the COVID-19 natural experience. Is hybrid work the optimal solution, the ideal compromise between the pros (saving commuting time) and the cons (loosing social integration) of WFH? This seems to be the aspiration of most workers worldwide. Does the demand for hybrid work also reflect a trade-off between life satisfaction and job satisfaction?

  • Loneliness during the COVID-19 pandemic: Evidence from five European countries Article dans une revue:

    We use quarterly panel data from the COME-HERE survey covering five European countries to analyse three facets of the experience of loneliness during the COVID-19 pandemic. First, in terms of prevalence, loneliness peaked in April 2020, followed by a U-shape pattern in the rest of 2020, and then remained relatively stable throughout 2021 and 2022. We then establish the individual determinants of loneliness and compare them to those found in the literature predating the COVID-19 pandemic. As in previous work, women are lonelier, and partnership, education, income, and employment protect against loneliness. However, the pandemic substantially shifted the age profile: it is now the youngest who are the loneliest. We last show that pandemic policies affected loneliness, which rose with containment policies but fell with government economic support. Conversely, the intensity of the pandemic itself, via the number of recent COVID-19 deaths, had only a minor impact. The experience of the pandemic has thus shown that public policy can influence societal loneliness trends.

In this paper we introduce a second effect of enforcement: it can also affect the capacity to learn about the group’s cooperativeness. Indeed, in contexts with strong enforcement, it is difficult to tell apart those who cooperate because of the threat of fines from those who are intrinsically cooperative types. Enforcement can then potentially have a negative dynamic impact on cooperation when it prevents learning. We provide theoretical and experimental evidence in support of this mechanism. Using a lab experiment with independent interactions and random rematching, we observe that, in early interactions, having faced an environment with fines in the past decreases current cooperation. We further show that this results from the interaction between enforcement and learning: the effect of having met cooperative partners has a stronger effect on current cooperation when this happened in an environment with no enforcement.

  • Forthcoming The Right Numeraire or the Just Weights? How to Make BCA Rational and Fair Article dans une revue:

    Unweighted benefit–cost analysis (BCA) based on aggregate willingness to pay might be, at long last, falling into disrepute, as it is widely recognized that it exhibits a bias toward the wealthy, and as alternatives are appearing more and more practicable. However, the choice of alternatives is often framed in terms of choosing an alternative metric to willingness to pay in money, such as willingness to pay in healthy life years, or a measure of subjective well-being. It is argued in this paper that (i) a simple summation of individuals’ willingness to pay in any numeraire (e.g., money, healthy life years) is bound to generate non-transitivity issues in a similar way as money-based BCA, and (ii) a metric such as subjective well-being involves distributional value judgments that are too specific to reflect the relevant spectrum in the public debate. The “orthodox” weighted BCA method, which links BCA to an underlying social welfare function, offers more flexibility and guarantees transitive choices. Fortunately, in some relevant cases, these various methods may provide similar results, and the main options currently proposed all give greater weight to the worse off in the population than does unweighted BCA.

  • Que penser des services exploitant les données de santé ? L’avis des adhérents d’une mutuelle en France Article dans une revue:

    Dans un contexte d’investissements massifs dans les données de santé, j’utilise une enquête quantitative menée en 2016 auprès de 1 700 adhérents d’une mutuelle pour appréhender les représentations sociales concernant l’usage des données de santé en France. L’enquête capte l’intérêt des adhérents pour différents services innovants de santé, qui seraient éventuellement proposés par la mutuelle et qui utiliseraient leurs données de santé. L’analyse dévoile que les répondants sont à la fois préoccupés par la sécurité de leurs données et intéressés par les services. Un adhérent se montre d’autant plus intéressé que son état de santé est dégradé et que ses inquiétudes pour ses vieux jours sont grandes. De plus, une position sociale moins favorable va de pair avec un intérêt plus fort pour les services, ce qui pourrait refléter l’existence d’inégalités sociales dans l’accès aux technologies de santé.

  • Accueillir les jeux olympiques rend-il heureux ? Article dans une revue:

    À l’aide d’une enquête de panel auprès de 26 000 personnes résidant à Londres, Paris et Berlin pendant les mois d’été de 2011, 2012 et 2013, les auteurs exploitent l’expérience quasi naturelle que constitue le choix de Londres comme ville d’accueil. Ils suivent une approche en différence de différences, afin d’identifier l’effet d’accueillir les Jeux olympiques (JO) à l’été 2012.Leurs résultats montrent que les JO d’été ont accru la satisfaction et le bonheur des Londoniens à court terme (c’est-à-dire pendant la période olympique), en particulier autour des cérémonies d’ouverture et de clôture. L’effet bénéfique sur les Londoniens est assez important, mais l’équivalent monétaire de ce gain en bien-être subjectif reste bien inférieur au coût réel de l’événement. Cependant, la conclusion est différente, si l’on suppose que l’effet hédonique s’étend à l’échelle du Royaume-Uni et non à la seule ville de Londres.

  • Mental health and the overall tendency to follow official recommendations against COVID-19: A U-shaped relationship? Article dans une revue:

    This paper investigates the association between several mental health indicators (depression, anxiety, stress, and loneliness) and the overall tendency to follow official recommendations regarding self-protection against COVID-19 (i.e., overall compliance). We employ panel data from the COME-HERE survey, collected over four waves, on 7,766 individuals (22,878 observations) from France, Germany, Italy, Spain, and Sweden. Employing a flexible specification that allows the association to be non-monotonic, we find a U-shaped relationship, in which transitions to low and high levels of mental health are associated with higher overall compliance, while transitions to medium levels of mental health are associated with less overall compliance. Moreover, anxiety, stress, and loneliness levels at baseline (i.e., at wave 1) also have a U-shaped effect on overall compliance later (i.e., recommendations are followed best by those with lowest and highest levels of anxiety, stress, and loneliness at baseline, while following the recommendations is lowest for those with moderate levels of these variables). These U shapes, which are robust to several specifications, may explain some of the ambiguous results reported in the previous literature. Additionally, we observe a U-shaped association between the mental health indicators and a number of specific health behaviours (including washing hands and mask wearing). Importantly, most of these specific behaviours play a role in overall compliance. Finally, we uncover the role of gender composition effects in some of the results. While variations in depression and stress are negatively associated with variations in overall compliance for men, the association is positive for women. The U-shaped relation in the full sample (composed of males and females) will reflect first the negative slope for males and then the positive slope for females.

  • Les opinions des conventionnels sur les mesures climatiques Chapitre d’ouvrage:

    Page de couverture Les démocraties peinent à répondre à la crise climatique. Une approche prometteuse pour la transition écologique repose sur des innovations impliquant des panels de citoyens tirés au sort. De nombreux pays ont expérimenté cette forme de démocratie délibérative au niveau national et local. Ces assemblées de citoyens formulent des propositions de politiques publiques. La Convention citoyenne pour le climat en France constitue le dispositif le plus important en termes de taille, de durée et de mandat. Grâce à une enquête de terrain multidisciplinaire impliquant une vingtaine de chercheurs, cet ouvrage permet de comprendre la complexité de cette expérience sous plusieurs angles : les procédures et le processus, l’identité et les rôles de ses membres, les rapports à l’expertise et aux représentants, l’évaluation et la comparaison avec d’autres cas. Démocratie délibérative et transition écologique offre une contribution majeure à la réflexion sur une pratique originale d’innovation démocratique et sur son potentiel pour une gouvernance juste des politiques climatiques.

  • I Can’t Forget About U: Lifetime Unemployment and Retirement Well-being Pré-publication, Document de travail:

    It is well-known that unemployment leaves scars after re-employment, but does this scarring effect persist even after retirement? We analyse European data on retirees from the SHARE panel, and show that the well-being of the retired continues to reflect the unemployment that they experienced over their working life. These scarring effects are somewhat smaller for older retirees, but larger for those who arguably had higher expectations regarding the labour market when they were active. The lower well-being from lifetime unemployment does not reflect lower retirement income. This long-run scarring for those who have left the labour market underlines that contemporaneous correlations significantly under-estimate the well-being cost of unemployment.

  • Twenty Years of Job Quality in OECD Countries: More Good News? Pré-publication, Document de travail:

    The distribution of job quality across workers and the change in job quality over time can be reflected in various measures of job outcomes, or single-item job-satisfaction scores. This paper takes both approaches to establish the evolution of job quality over a period from the mid-1990s to the mid-2010s in 13 OECD countries, using data from the three latest ISSP Work Orientation modules. The rise in job satisfaction from 1997 to 2005 has continued through 2015, despite the 2008 Great Recession. This improvement is also found in most of the joboutcome domains, despite some evidence of harder and more stressful work. Workers reported that job security was the most-important job aspect every year, and the percentage of workers with secure jobs rose over time. There has been a small rise in the dispersion of job satisfaction, but the good news regarding better job quality over a 20-year period does not seem to be dampened by large changes in its inequality.

  • Commitment to the truth creates trust in market exchange: Experimental evidence Article dans une revue:

    Under incomplete contracts, the mutual belief in reciprocity facilitates how traders create value through economic exchange. Creating such beliefs among strangers can be challenging even when they are allowed to communicate, because communication is cheap. In this paper, we first extend the literature showing that a truth-telling oath increases honesty to a sequential trust game with pre-play, fixed-form, and cheap-talk communication. Our results confirm that the oath creates more trust and cooperative behavior thanks to an improvement in communication; but we also show that the oath induces selection into communication -it makes people more wary of using communication, precisely because communication speaks louder under oath. We next designed additional treatments featuring mild and deterrent fines for deception to measure the monetary equivalent of the non-monetary incentives implemented by a truth-telling oath. We find that the oath is behaviorally equivalent to mild fines. The deterrent fine induces the highest level of cooperation. Altogether, these results confirm that allowing for interactions under oath within a trust game with communication creates significantly more economic value than the identical exchange institutions without the oath.

  • Précis d’Economie Comportementale Ouvrages:

    Du matin au soir, nous faisons toutes sortes de choix : conduire ou prendre le vélo, aller au supermarché ou à l’épicerie. Si ces décisions quotidiennes s’enchaînent souvent sans même qu’on en ait conscience, elles s’ajoutent à des décisions dont les enjeux sont autrement plus importants, qu’ils soient économiques, financiers, ou d’ordre environnemental, sociologique et culturel. Quels processus de décision se cachent derrière les réalités sociales qui déterminent le fonctionnement de l’économie ? Comment définir les coûts et les bénéfices entre lesquels nous devons arbitrer ? Pourquoi même l’absence de choix est-elle une forme de décision ? Comment les décisions individuelles se combinent-elles avec les décisions collectives ? Quelle est la palette d’outils permettant d’orienter les comportements ? L’économie comportementale apporte des réponses à ces questions en étudiant les décisions économiques à travers le prisme de facteurs rationnels, la comparaison des coûts et des bénéfices, mais aussi psychologiques, tels que les ressources cognitives, le contexte et le comportement des pairs.

  • L’économie comportementale murmure à l’oreille du juriste Article dans une revue:

    Longtemps confinée à l’efficacité de la protection des droits de propriété nécessaires aux échanges de marché, l’analyse économique du droit trouve en grande partie ses origines dans la nécessité de pallier les défaillances de marché associées à la remise en cause des conditions qui rendent leur fonctionnement efficace. Cette branche de l’économie s’intéresse en particulier à la capacité de différentes règles juridiques à corriger les inefficacités structurelles qui en découlent, par exemple en matière de comportements de prévention des risques liés aux activités humaines ou encore de comportements délictuels. Les développements récents de l’économie comportementale apportent un éclairage nouveau sur la réponse des acteurs de l’économie aux règles qui leur sont appliquées, et conduisent en particulier à un renouvellement profond des recommandations de l’économie en matière d’élaboration des règles de droit. Cet article en présente un panorama, appliqué notamment aux régimes de responsabilité civile et aux modalités d’application de la politique pénale.

  • Do wages underestimate the inequality in workers’ rewards? The joint distribution of job quality and wages across occupations Article dans une revue:

    Information on both wages and job quality is needed in order to understand the occupational dispersion of wellbeing. We analyse subjective wellbeing in a large UK sample to construct a measure of ‘overall reward’, the sum of wages and the value of job quality, in 90 different occupations. If only wages are included, then labour market inequality is underestimated: the dispersion of overall rewards is one‐third larger than the dispersion of wages. Our findings are similar, and stronger, in data on US workers. We find a positive correlation between job quality and wages in all specifications, both between individuals in the cross‐section and within individuals in panel data. The gender and ethnic gaps in the labour market are larger than those in wages alone, and the overall rewards to education on the labour market are underestimated by earnings differentials alone.

  • Where does money matter more? Article dans une revue:

    There is much still to learn about the relationship between income and well-being, and in particular how this may depend on the economic and social context. We use Russian data to estimate individual Welfare Functions of Income, and examine two potentially context-dependent concepts: self-assessed income needs and welfare sensitivity to income (how well-being changes with income). The considerable geographical diversity in Russia provides within-country variation in GDP, inequality, population density, and unemployment. We first show that income needs exceed actual income on average in Russia, and that these needs are less sensitive to changes in income than in other countries. Second, income needs vary by individual characteristics, while welfare sensitivity does not. Welfare sensitivity is however related to the regional context. Last, our estimated contextual results help us to understand why the existing literature has produced such a wide range of results.

  • Taking Back Control? Quasi-Experimental Evidence on the Impact of Retirement on Locus of Control Article dans une revue:

    We use Australian panel data to examine the impact of retirement on individual locus of control, a socio-emotional skill with substantial explanatory power for a broad range of life outcomes. Exploiting the eligibility age for the Australian Age Pension, we find that retirement leads to increased internal locus of control. This greater internal control explains around one-third and one-fifth of the positive effects of retirement on health and subjective well-being, respectively. We also show that locus of control is much more malleable at retirement than the other socio-emotional skills of the Big-Five personality traits, risk and time preferences, and trust.

  • La multipropriété, c’est l’envol Article dans une revue:

    Dans le football, la multipropriété de clubs (en anglais multi-club ownership – MCO) concerne aussi bien des propriétaires individuels, des groupes ou des clubs. C’est un phénomène plutôt récent qui date de la fin des années 1990, mais qui semble prendre de l’ampleur dans le football aujourd’hui. Économiquement, cette évolution de la MCO s’inscrit dans une logique de fusions-acquisitions d’entreprises qui est une pratique courante dans une économie de marché. Elles peuvent alors être « horizontales » (rachat de clubs de même niveau), « verticales » (rachat de clubs formateurs), ou encore viser une « extension du marché » (rachat de clubs d’autres régions). D’un point de vue sportif, cette pratique pose des problèmes évidents de conflit d’intérêts, si deux équipes d’une MCO sont amenées à se rencontrer dans une même compétition. L’UEFA (Union of European Football Associations) a (pour l’instant) réglé ces problèmes d’éthique sportive avec la jurisprudence Red Bull basée sur son concept d’« influence décisive » d’un club sur un autre.

  • Alternatives to plurality rule for single-winner elections: When do they make a difference? Article dans une revue:

    Declining levels of turnout and growing distrust in political elites are often seen as symptoms of a crisis of representative democracy. Various proposals of reform have been made to reinvigorate representation and political participation. This paper focuses on one aspect of that debate: finding an alternative to FPTP, which is the electoral rule most frequently used in single-member districts, but which is criticized, among others, for allowing only a limited expression of voters’ preferences. Many alternative rules are in use or have been suggested, such as Two-Round majority, Instant Runoff, Approval Voting, Majority Judgement, or Range Voting. The literature on these decision rules has concentrated on their formal properties. Yet, we know surprisingly little about how frequently these rules would lead to different outcomes in normal electoral settings. This paper improves our understanding of these rules by examining their mechanical effects. We start from data on voters’ party utilities from “real-world” settings, based on CSES data. This allows simulating and comparing the outcomes of different electoral rules under a variety of distributions of voters’ party preferences. We then analyze how frequently they lead to different outcomes and identify the contextual characteristics that explain these differences. For the latter question, we focus on a number of party system or electorate’s characteristics, which have been highlighted in debates on challenges to representation (such as ideological polarization, party system fragmentation, or affective polarization).

  • Efficiency and equity in a socially-embedded economy Article dans une revue:

    A model that only focuses on economic relations, and in which efficiency and equity are defined in terms of resource allocation may miss an important part of the picture. We propose a canonical extension of the standard general equilibrium model that embeds economic activities in a larger game of social interactions. Such a model combines general equilibrium effects with social multiplier effects and considerably enriches the analysis of efficiency and equity. Efficiency involves coordination between economic and social interactions, may depend on social norms, and may strongly interact with the distribution of resources. Equity can be defined in a comprehensive, socioeconomic way, and a decomposition into an economic and a social component is possible.

  • The association between consideration of future consequences and food intake is mediated by food choice motives in a French adult population Article dans une revue:

    Objectives: Consideration of future consequences (CFC) distinguishes individuals who adopt behaviors based on immediate needs and concerns from individuals who consider the future consequences of their behaviors. We aimed to assess the association between CFC and diet, and testing the mediating role of food choice motives on this relationship. Design: Individuals (age≥18 years) completed the CFC-12 questionnaire in 2014, at least three 24-h dietary records, and a food choice motive questionnaire. A multiple mediator analysis allowed to assess the mediating effect of food choice motives on the cross-sectional association between CFC and diet, adjusted for socio-demographic factors. Setting: Data from the NutriNet-Santé cohort study. Participants: 27,330 participants. Results: CFC was associated with all food choice motives (P < 0.001), with the strongest positive associations for avoidance for environmental reasons, absence of contaminants and health motives, and the strongest negative associations for innovation and convenience). Positive total effects were found between CFC and the consumption of healthy food groups (fruits and vegetables, whole-grain foods, legumes); and negative total effects for alcohol, meat and poultry and processed meat (P < 0.001). CFC was positively associated with diet quality (P < 0.001). Across food groups, major mediators of these relationships were higher health (8.4-32.6%), higher environmental (13.7-22.1 %) and lower innovation (7.3-25.1 %) concerns. Conclusions: CFC was associated with healthier dietary intake, essentially mediated by a greater motivation of future-oriented participants for self-centered and altruistic outcomes, including health and environment. Focusing on the awareness of future benefits in public health interventions might lead to healthier dietary behaviors.

  • Does universalization ethics justify participation in large elections? Pré-publication, Document de travail:

    What drives voters’ decisions to participate in large elections under costly voting, despite the rational expectation that this has no impact on the outcome? We propose a new model of ethical voters, by positing that they have Kantian or semi-Kantian preferences. With such preferences, voters evaluate their behavior in light of what the outcome would be, should a fraction of the other voters choose the same course of action. The “other voters” can be either the entire population (“non-partisan ethics”) or the individuals with same interest (“partisan ethics”). In a model with two candidates and a continuum of voters, we find that turnout is strictly positive as soon as the evaluation by the voters of the political outcome is not strictly of the “winner-take-all” kind. Moreover, the equilibrium turnout rates depend on the specifics of the election at hand, such as the relative stake of the election for the two supporter groups and the presence of core constituent groups.

  • Unsettled: Job Insecurity Reduces Home-Ownership Pré-publication, Document de travail:

    We here evaluate the link between job insecurity and one of the most-important decisions that individuals take: homeownership. The 1999 rise in the French Delalande tax on firms that laid off older workers produced an unexpected exogenous rise in job insecurity for younger workers. A difference-in-differences analysis of panel data from the European Community Household Panel shows that this greater job insecurity significantly reduced the probability of becoming a homeowner. This drop seems more attributable to individual preferences rather than greater capital constraints, consistent with individuals reducing their exposure to long-term financial commitments in more-uncertain environments.

  • All (electoral) politics is local? Candidate’s regional roots and vote choice Article dans une revue:

    Many authors argue that candidates are more popular among voters from their own region. Two potential explanations have been suggested: voters’ identification with their home region, and the representation of regional interests. The information on candidates’ residence can be transmitted to voters in different ways, the most easily accessible way being information printed on the ballot paper. However, most studies on “friends and neighbour voting” use aggregate data. Studies that rely on individual level data usually put respondents in hypothetical situations and confront them with synthetic candidates, reducing their realism. To bridge this gap and to test the effect of providing information on the candidates’ residence, we use data from a survey experiment to analyze voters’ responses to ballot paper information on the regional background of real candidates in the 2014 European election in Germany. We find that voters in an open list PR election are more likely to support regional candidates if ballot paper information on the candidates’ geographic background helps them to do so. The appeal of personal ties is a stronger explanation for vote preference than the one based on regional interests.

    We carry out a difference-in-differences analysis of a representative real-time survey conducted as part of the German Socio-Economic Panel (SOEP) study and show that teleworking had a negative average effect on life satisfaction over the first two years of the COVID-19 pandemic. This average effect hides considerable heterogeneity reflecting genderrole asymmetry: lower life satisfaction is only found for unmarried men and women with school-age children. The negative effect for women with school-age children disappears in 2021, suggesting adaptation to new constraints and/or the adoption of coping strategies.

  • Specificity and sensitivity of the fixed-point test for binary mixture distributions Article dans une revue:

    When two cognitive processes contribute to a behavioral output—each process producing a specific distribution of the behavioral variable of interest—and when the mixture proportion of these two processes varies as a function of an experimental condition, a common density point should be present in the observed distributions of the data across said conditions. In principle, one can statistically test for the presence (or absence) of a fixed point in experimental data to provide evidence in favor of (or against) the presence of a mixture of processes, whose proportions are affected by an experimental manipulation. In this paper, we provide an empirical diagnostic of this test to detect a mixture of processes. We do so using resampling of real experimental data under different scenarios, which mimic variations in the experimental design suspected to affect the sensitivity and specificity of the fixed-point test (i.e., mixture proportion, time on task, and sample size). Resampling such scenarios with real data allows us to preserve important features of data which are typically observed in real experiments while maintaining tight control over the properties of the resampled scenarios. This is of particular relevance considering such stringent assumptions underlying the fixed-point test. With this paper, we ultimately aim at validating the fixed-point property of binary mixture data and at providing some performance metrics to researchers aiming at testing the fixed-point property on their experimental data.

  • De quoi l’homogamie économique est-elle le signe ? Une application à l’Allemagne de l’Ouest Article dans une revue:

    L’homogamie économique est un phénomène largement documenté, qui est souvent interprété comme résultant d’une préférence pour l’entre-soi. Pourtant, les caractéristiques des conjoints dans un ménage conditionnent non seulement leur satisfaction à être ensemble mais également leurs décisions de division du travail. Nous présentons dans cet article une approche qui englobe à la fois le processus de formation des couples, le partage des ressources au sein du ménage, et la complémentarité des conjoints dans les activités du couple. Appliquée à l’Allemagne entre 2013 et 2019, cette approche montre que l’homogamie salariale est concentrée dans le haut de la distribution, que l’éducation a un poids très important dans les complémentarités des conjoints, et que le salaire et l’éducation jouent un rôle similaire dans les modalités de partage du revenu du ménage.

  • Are the Upwardly-Mobile More Left-Wing? Pré-publication, Document de travail:

    It is well-known that the wealthier are more likely to have Right-leaning political preferences. We here in addition consider the role of the individual’s starting position, and in particular their upward social mobility relative to their parents. In 18 waves of UK panel data, both own and parental social status are independently positively associated with Rightleaning voting and political preferences: given their own social status, the upwardly-mobile are therefore more Left-wing.We investigate a number of potential mediators: these results do not reflect the relationship between well-being and own and parents’ social status, but are partly linked to the individual’s beliefs about how fair society is. We replicate these findings using US data and show that, in both countries, the choice of specification when controlling for the respondent’s own status is crucial and may help explain some of the mixed findings in the literature.

Au premier plan des préoccupations des Français, les chocs de l’inflation et de la guerre en Ukraine se conjuguent avec le réchauffement climatique pour nourrir une forte inquiétude vis-à-vis de l’avenir. Cette anxiété s’ajoute à la tendance structurelle au pessimisme des Français. Cette dernière se lit d’ailleurs dans la manière dont ils se représentent leur société et sa stratification, souvent en décalage avec la perception de leur propre situation, ce qui fait apparaître un étonnant mélange de malheur public et de bonheur privé. Parallèlement, la société se transforme, notamment le monde professionnel, avec l’installation durable du travail à distance dans les pratiques. C’est au prisme du bien-être subjectif que nous analysons ces différentes tendances de la société française.

  • Inflation des prix alimentaires : quelles conséquences possibles pour les ménages modestes ? Article dans une revue:

    Les prix alimentaires augmentent de manière importante depuis maintenant plus d’une année. Les résultats provisoires publiés par l’Insee en janvier 2023 montrent une hausse de 13,2 % depuis janvier 2022, plus du double de la hausse de l’indice des prix (+6 %) et un peu moins que le prix de l’énergie (+16 %) [1]. Les données détaillées publiées par l’institut IRI montrent que les hausses de prix touchent particulièrement les aliments de base et les produits dits de « fond de placard », comme les huiles, le riz, le sucre ou les steaks hachés [2]. Les prix des produits « premiers prix » et de marques de distributeurs augmentent plus fortement que celui des marques nationales (+17,8 % pour les premier set +11,6 % pour les secondes [3]), probablement à cause de marges plus faibles qui obligent à transmettre plus directement la hausse des coûts des approvisionnements sur le prix final. Les déterminants de ces hausses de prix sont multiples et bien identifiés. Ils tiennent, tout d’abord, à des chocs sur la production agricole et alimentaire au niveau international et sur la logistique des chaînes de distribution : guerre en Ukraine, disruption des chaînes logistiques liées à la pandémie du Covid-19 et aux tensions géopolitiques, impacts de catastrophes météorologiques liées au réchauffement climatique comme les inondations au Pakistan. Ensuite, la croissance de la demande alimentaire de certains pays, notamment la Chine, déstabilise structurellement les marchés agro-alimentaires, en partie du fait de la politique du gouvernement chinois qui vise à assurer la sécurité alimentaire par la constitution de stocks et sans coordination avec les autres pays [4]. Quelles peuvent être les conséquences de ces hausses de prix brutales sur les choix des consommateurs franc¸ais, notamment les plus défavorisés ?

  • Anticipating the Risk of Dependency and Assets Article dans une revue:

    The significant gains in life expectancy at advanced ages that have been recorded over recent decades, combined with the arrival of the baby boom generations at old age, suggest a rapid growth in the costs of long-term care. This perspective fuels debates on the most suitable method for financing the loss of autonomy: in the absence of sufficiently broad insurance coverage and given the difficulty of evaluating both the probability of becoming dependent and the attendant costs, the risk is high that households will not save enough. This article addresses the issue: by drawing on data from the 2020 wave of the Pat€r survey, we evaluate to what extent households adapt their savings effort in function of their estimation of the probability that they will lose their autonomy on the medical level. To this end, we estimate household assets according to their own assessment of the risk of becoming dependent one day, controlling notably for their self-reported health status. To account for the possible endogeneity of expected dependency risk on household savings (people save less if their health is poor), we use instrumental variable estimation methods. Our results confirm that people with a higher self-assessment of the risk of becoming dependent accumulate more assets: measured at the average self-assessed risk, an increase of this risk by one standard deviation is associated with an increase in overall gross wealth of three to eight months of permanent income.

  • Opposite ethical views converge under the threat of catastrophic climate change Pré-publication, Document de travail:

    Climate policy is often described by economists as an intertemporal consumption trade-off: consume all you want today and face climate damages in the future, or sacrifice consumption today to implement costly climate policies that will bring future benefits through avoided climate damages. If one assumes enduring technological progress, a society that is more averse to intertemporal inequalities should postpone climate policies and let future, richer generations pay more. Growing evidence however suggests that the trade-off is more complex: abrupt, extreme, irreversible changes to the climate may cause discontinuities to socio-economic systems, possibly leading to a sharp decline of human population and consumption per capita. In this paper, we show that, when accounting for a very small risk of catastrophic climate change, it is optimal to pursue stringent climate policies to postpone the catastrophe. Our results conform with the well-known conclusion that tight carbon budgets are preferred when aversion towards inequalities between generations is low. However, by contrast with previous studies, we show that stringent policies are also optimal when inequality aversion is high. The non-monotonicity of the influence of inequality aversion is due to the fact that, for a given investment in abatement, a higher inequality aversion gives a smaller weight to avoided future non-catastrophic damages, but a larger weight to the catastrophic outcome. We also explore the role of population ethics, and show that the size of the optimal carbon budget decreases with the social preference for large populations, although this parameter plays almost no role at extreme levels of inequality aversion. Our result demonstrates that views from opposite sides of the ethical spectrum in terms of inequality aversion converge in terms of climate policy recommendations, warranting immediate climate action.

  • Measuring well-being and lives worth living Article dans une revue:

    We study the measurement of well-being when individuals have heterogeneous preferences, including dierent conceptions of a life worth living. When individuals dier in the conception of a life worth living, the equivalent income can regard an individual whose life is not worth living as being better o than an individual whose life is worth living. In order to avoid this paradoxical result, we reexamine the ethical foundations of well-being measures in such a way as to take into account heterogeneity in the conception of a life worth living. We derive, from simple axioms, an alternative measure of well-being, which is an equivalent income net of the income threshold making lifetime neutral. That new well-being index always ranks an individual whose life is not worth living as worse-o than an individual with a life worth living.

  • Ordinal Variables and the Measurement of Upward and Downward Intergenerational Educational Mobility in European Countries Article dans une revue:

    This article proposes a new approach to the measurement of intergenerational mobility in education. Borrowing the concept of inequality-sensitive and additive achievement measure axiomatically developed by Apouey et al., we derive new indices of upward, downward, and total mobility, using a « movement approach. » It turns out that the Prais-Bibby and Bartholomew mobility indices are particular cases of the mobility indices we introduce. We then present an empirical illustration based on the 2016 European Social Survey. Particular attention is given to within country differences between fathers to children and mothers to children educational mobility. When comparing two countries, we also make a distinction between gross and net mobility, the latter referring to the case where country differences in the educational structure of parents and children are neutralized.

  • Le droit à l’information sur la retraite introduit par la réforme de 2003 rend-il les Français mieux informés et moins inquiets quant à leur future retraite ? Article dans une revue:

    Nous étudions l’impact de la politique d’envoi aux assurés d’une information personnalisée sur leur retraite, introduite par la réforme de 2003 (le droit à l’information, DAI), sur l’amélioration de la connaissance qu’ont ces derniers de leurs droits à retraite et sur l’évolution de leur inquiétude concernant le montant de leur pension future. En mobilisant les données des vagues 2012 et 2020 de l’enquête Pat€r, nous montrons que la connaissance des droits à la retraite s’est améliorée et que l’inquiétude sur le montant des pensions s’est réduite entre 2012 et 2020. L’impact des envois d’information dans le cadre du DAI est difficile à isoler de celui de l’évolution du contexte général entre 2012 et 2020. Les résultats obtenus suggérent toutefois un léger effet positif de la politique du DAI sur la connaissance avec le premier envoi de documents et un effet indirect sur la réduction de l’inquiétude via l’amélioration de la connaissance.

  • « Football is not a Big Business but is Doing Well » ou la transformation du modèle économique du football anglais Article dans une revue:

    Comment expliquer économiquement le passage du people’s game au global game ? Pourquoi Manchester City, par exemple, dont les origines se trouvent dans un paternalisme paroissial à St Mark’s peut adopter aujourd’hui une stratégie de domination mondiale du football à travers le City Football Group ? La réponse à ces questions est bien entendu plurielle et s’appuie sur une histoire non linéaire. Le football connait un fort succès populaire depuis ses origines jusqu’aux années 1950-1960. Le beautiful game entre ensuite dans sa période « sombre » pour différentes raisons : récession des années 1980, vétusté des stades, hooliganisme, entre autres. La « renaissance » à partir des années 1990 se nourrit notamment de la création de la Premier League, de la très forte croissance des droits TV et de la mondialisation du football anglais.

  • Maternal genetic risk for depression and child human capital Article dans une revue:

    We here address the causal relationship between the maternal genetic risk for depression and child human capital using UK birth-cohort data. We find that an increase of one standard deviation (SD) in the maternal polygenic risk score for depression reduces their children’s cognitive and non-cognitive skill scores by 5 to 7% of a SD throughout adolescence. Our results are robust to a battery of sensitivity tests addressing, among others, concerns about pleiotropy and dynastic effects. Our Gelbach decomposition analysis suggests that the strongest mediator is genetic nurture (through maternal depression itself), with genetic inheritance playing only a marginal role.

  • Experiential values are underweighted in decisions involving symbolic options Article dans une revue:

    Standard models of decision-making assume each option is associated with subjective value, regardless of whether this value is inferred from experience (experiential) or explicitly instructed probabilistic outcomes (symbolic). In this study, we present results that challenge the assumption of unified representation of experiential and symbolic value. Across nine experiments, we presented participants with hybrid decisions between experiential and symbolic options. Participants’ choices exhibited a pattern consistent with a systematic neglect of the experiential values. This normatively irrational decision strategy held after accounting for alternative explanations, and persisted even when it bore an economic cost. Overall, our results demonstrate that experiential and symbolic values are not symmetrically considered in hybrid decisions, suggesting they recruit different representational systems that may be assigned different priority levels in the decision process. These findings challenge the dominant models commonly used in value-based decision-making research.

  • Universalization and altruism Article dans une revue:

    The kappa-universalization of a symmetric game is the game in which each player considers that any other player chooses with probability kappa the same stategy as she. To any normal form game, we associate the symmetric two-stage game in which, in a first stage, the roles to be played in the base game are randomly assigned. We show that any pure strategy equilibrium of the kappa-universalization of this extended game is an equilibrium of the base game played by altruistic players (« ex ante Homo Moralis equilibrium is altruistic »), and that the converse is false. The paper presents the implications of this remark for the philosophical nature of ethical behavior (Kantianism behind the veil of ignorance implies but is stronger than altruism) and for its evolutionary foundations.

  • Time-Use and Subjective Well-Being: Is Diversity Really the Spice of Life? Article dans une revue:

    Using the American and the French time-use surveys, we examine whether people have a preference for a more diversified mix of activities, in the sense that they experience greater well-being when their time schedule contains many different activities rather than is concentrated on a very small number. This could be due to decreasing marginal utility, as is assumed for goods consumption, if each episode of time is conceived as yielding a certain level of utility per se. With returns to specialization, people would then face a trade-off between efficiency and diversity in choosing how to allocate time. We examine these issues and investigate potential gender differences, considering both instantaneous feelings and life satisfaction.

  • Alcohol Price Regulation in France: Choosing a Reform Scenario to Achieve Public Health and Tax Fairness Objectives Article dans une revue:

    Public health authorities advocate the introduction of alcohol pricing policies in the form of tax reform and/or a minimum unit price based on the pure alcohol content of products. We use Kantar WorldPanel household purchase data to describe the distortions in the current tax system, favouring wine and penalising low-income households. We assess the potential impact of reform sce­narios that replace current taxes with a single excise tax (flat or progressive) on pure alcohol content and/or the introduction of a minimum price per gram of pure alcohol. Introducing a minimum price while leaving taxation unchanged would have the advantage of raising alcohol prices, especially for low-end wines, which are prized by abusive consumers. The impact would a priori be limited in terms of tax regressivity and for higher quality segments, which is important for the wine sector.

  • Do individuals adapt to all types of housing transitions? Article dans une revue:

    This paper provides one of the first tests of adaptation to the complete set of residential transitions. We use long-run SOEP panel data and consider the impact of all housing transitions, whether or not they involve a change in housing tenure or geographical movement, on both life satisfaction and housing satisfaction. Controlling for individual characteristics, some residential transitions affect life satisfaction only little, while all transitions have a significant effect on housing satisfaction. This latter is particularly large for renters who become homeowners and move geographically, and for renters who move without changing tenure status. Regarding housing satisfaction, we only uncover evidence of some adaptation for renter-renter moves. Losing homeowner status is the only transition that produces lower housing satisfaction, and here the effect seems to become even more negative over time.

  • Préférences et croyances pendant le « grand confinement » : l’épargnant face au risque Article dans une revue:

    La psyché des individus est-elle susceptible de changer pendant les crises ? Inversement, pour paraphraser Stigler et Becker [1977], les préférences individuelles sont-elles « solides comme un roc », en d’autres termes stables temporellement ? Même si théoriquement, les économistes privilégient la stabilité des préférences sur l’instabilité, savoir si des chocs, qu’ils soient démographiques, sanitaires, naturels, conflictuels ou économiques, sont susceptibles de modifier les paramètres de goût des individus et, en conséquence, leur comportement, est une question importante en matière de politique publique. De nombreux travaux empiriques cherchent aujourd’hui à tester si les préférences évoluent, ou non, dans le temps, ou encore si elles sont durablement modifiées par des événements de la vie ou des chocs structurels auxquels sont confrontés les individus. Les conclusions dépendent de l’origine des chocs, de la méthodologie adoptée pour mesurer les préférences et de la nature des questions posées. Le choc de la pandémie de la Covid-19 de 2020 est une nouvelle opportunité pour étudier cette question de la stabilité des goûts. Il existe déjà de nombreuses études qui ont analysé l’impact de la crise de la Covid sur les épargnants mais qui n’aboutissent à aucun consensus sur le sens de l’impact de la crise sanitaire sur les préférences. Pour la France, les traitements statistiques réalisés ici à partir de l’enquête Pat€r 2020 montrent plutôt une stabilité des préférences vis-à-vis du risque : le « grand confinement » n’aurait ainsi eu que peu d’impact sur les préférences de l’épargnant.

  • Marriage as insurance: job protection and job insecurity in France Article dans une revue:

    Job insecurity is one of the risks that workers face on the labour market. As with any risk, individuals can choose to insure against it, and we here consider marriage as one potential source of this insurance. The 1999 rise in the French Delalande tax, paid by larger private firms when they laid off workers aged 50 or over, led to an exogenous rise in job insecurity for the uncovered (younger workers) in these larger firms. A difference-in-differences analysis using French panel data reveals that this greater job insecurity for the under-50s led to a significant rise in their probability of marriage, and especially when the partner had greater job security, consistent with marriage providing insurance against labour-market risk.

  • Economic analysis of the 12th man: should the fans be paid? Article dans une revue:

    The paper provides a theoretical sports league model to study the pricing of tickets. It considers the trade-off between maximizing match day revenues, through high prices, and maximizing the support of the most demonstrative fans, through low prices. These spectators, the “ultras” contribute to the competitive level of the club along with team-level talent, and therefore indirectly increase the number of victories, hence the revenue from TV rights. We model the role of effusive spectators and show that, in a non-cooperative Nash equilibrium, it may be optimal for the club to subsidize their presence in order to take full advantage of the 12th man effect.

  • Adopting telework: The causal impact of working from home on subjective well‐being Article dans une revue:

    We study the impact of work from home (WFH) on subjective well‐being during the Covid period, where self‐selection of individuals into telework is ruled out, at least part of the time, by stay‐at‐home orders. We use a difference‐in‐differences approach with individual fixed effects and identify the specific impact of switching to telecommuting, separately from any other confounding factor. In particular, our identification strategy avoids the influence of interpersonal heterogeneity by exploiting the multiple entries into WFH, by the same individuals, at different times. On average over the period, switching to WFH, especially full‐time, worsens mental health. We also find a positive but imprecisely measured impact of part‐time WFH on life satisfaction. However, this hides a dynamic evolution, whereby the initial deterioration gives place to an adaptation process after a couple of months. We also uncover a particularly pronounced fall in subjective well‐being of women with children, especially in the first months; this could be associated with home‐schooling.

  • Neural and computational underpinnings of biased confidence in human reinforcement learning Article dans une revue:

    While navigating a fundamentally uncertain world, humans and animals constantly evaluate the probability of their decisions, actions or statements being correct. When explicitly elicited, these confidence estimates typically correlates positively with neural activity in a ventromedial-prefrontal (VMPFC) network and negatively in a dorsolateral and dorsomedial prefrontal network. Here, combining fMRI with a reinforcement-learning paradigm, we leverage the fact that humans are more confident in their choices when seeking gains than avoiding losses to reveal a functional dissociation: whereas the dorsal prefrontal network correlates negatively with a condition-specific confidence signal, the VMPFC network positively encodes task-wide confidence signal incorporating the valence-induced bias. Challenging dominant neuro-computational models, we found that decision-related VMPFC activity better correlates with confidence than with option-values inferred from reinforcement-learning models. Altogether, these results identify the VMPFC as a key node in the neuro-computational architecture that builds global feeling-of-confidence signals from latent decision variables and contextual biases during reinforcement-learning.

  • Pandemic preparedness and response: beyond the Access to COVID-19 Tools Accelerator Article dans une revue:

    Nationalism has trumped solidarity, resulting in unnecessary loss of life and inequitable access to vaccines and therapeutics. Existing intellectual property (IP) regimens, trade secrets and data rights, under which pharmaceutical firms operate, have also posed obstacles to increasing manufacturing capacity, and ensuring adequate supply, affordable pricing, and equitable access to COVID-19 vaccines and other health products in low-income and middle- income countries. We propose: (1) Implementing alternative incentive and funding mechanisms to develop new scientific innovations to address infectious diseases with pandemic potential; (2) Voluntary and involuntary initiatives to overcome IP barriers including pooling IP, sharing data and vesting licences for resulting products in a globally agreed entity; (3) Transparent and accountable collective procurement to enable equitable distribution; (4) Investments in regionally distributed research and development (R&D) capacity and manufacturing, basic health systems to expand equitable access to essential health technologies, and non-discriminatory national distribution; (5) Commitment to strengthen national (and regional) initiatives in the areas of health system development, health research, drug and vaccine manufacturing and regulatory oversight and (6) Good governance of the pandemic prevention, preparedness and response accord. It is important to articulate principles for deals that include reasonable access conditions and transparency in negotiations. We argue for an equitable, transparent, accountable new global agreement to provide rewards for R&D but only on the condition that pharmaceutical companies share the IP rights necessary to produce and distribute them globally. Moreover, if countries commit to collective procurement and fair pricing of resulting products, we argue that we can greatly improve our ability to prepare for and respond to pandemic threats.

  • Well-being and working from home during COVID-19 Article dans une revue:

    Purpose The authors track the well-being of individuals across five European countries during the course of the coronavirus disease 2019 (COVID-19) pandemic and relate their well-being to working from home. The authors also consider the role of pandemic-policy stringency in affecting well-being in Europe. Design/methodology/approach The authors have four waves of novel harmonised longitudinal data in France, Italy, Germany, Spain and Sweden, covering the period May–November 2020. Well-being is measured in five dimensions: life satisfaction, a worthwhile life, loneliness, depression and anxiety. A retrospective diary indicates whether the individual was working in each month since February 2020 and if so whether at home or not at home. Policy stringency is matched in per country at the daily level. The authors consider both cross-section and panel regressions and the mediating and moderating effects of control variables, including household variables and income. Findings Well-being among workers is lower for those who work from home, and those who are not working have the lowest well-being of all. The panel results are more mitigated, with switching into working at home yielding a small drop in anxiety. The panel and cross-section difference could reflect adaptation or the selection of certain types of individuals into working at home. Policy stringency is always negatively correlated with well-being. The authors find no mediation effects. The well-being penalty from working at home is larger for the older, the better-educated, those with young children and those with more crowded housing. Originality/value The harmonised cross-country panel data on individuals’ experiences during COVID-19 are novel. The authors relate working from home and policy stringency to multiple well-being measures. The authors emphasise the effect of working from home on not only the level of well-being but also its distribution.

  • Life Satisfaction and the Human Development Index Across the World Article dans une revue:

    We use annual data on over 150 countries between 2005 and 2018 to look at the relationship between subjective well-being (both cognitive and affective) and the Human Development Index (HDI). The HDI appears to be more closely related to cognitive than affective well-being. We also consider the relationships between the three HDI components (the Income, Health, and Education Indices) and well-being, and find that, on average, the Income Index has the strongest predictive power. Importantly, we find that the three HDI components only matter equally in Western and rich countries. Our analysis contributes to the discussion about cultural sensitivity in paradigms of societal development in two ways. We first show that differences in preferences toward development aims exist. Second, we propose a weighting procedure for a culturally-sensitive version of the HDI.

  • A shared brain system forming confidence judgment across cognitive domains Article dans une revue:

    Confidence is typically defined as a subjective judgment about whether a decision is right. Decisions are based on sources of information that come from various cognitive domains and are processed in different brain systems. An unsettled question is whether the brain computes confidence in a similar manner whatever the domain or in a manner that would be idiosyncratic to each domain. To address this issue, human participants performed two tasks probing confidence in decisions made about the same material (history and geography statements), but based on different cognitive processes: semantic memory for deciding whether the statement was true or false, and duration perception for deciding whether the statement display was long or short. At the behavioral level, we found that the same factors (difficulty, accuracy, response time, and confidence in the preceding decision) predicted confidence judgments in both tasks. At the neural level, we observed using functional magnetic resonance imaging that confidence judgments in both tasks were associated to activity in the same brain regions: positively in the ventromedial prefrontal cortex and negatively in a prefronto-parietal network. Together, these findings suggest the existence of a shared brain system that generates confidence judgments in a similar manner across cognitive domains.

  • Choosing an electoral rule: Values and self-interest in the lab Article dans une revue:

    We study the choice of multi-person bargaining protocols in the context of politics. In politics, citizens are increasingly involved in the design of democratic rules, for instance via referendums. If they support the rule that best serves their self-interest, the outcome inevitably advantages the largest group. In this paper, we challenge this pessimistic view with an original lab experiment, in which 252 subjects participated. In the first stage, these subjects experience elections under plurality and approval voting. In the second stage, they decide which rule they want to use for extra elections. We find that egalitarian values that subjects hold outside of the lab shape their choice of electoral rule in the second stage when a rule led to a fairer distribution of payoffs compared to the other one in the first stage. The implication is that people have consistent ‘value-driven preferences’ for decision rules.

    La 23e édition de la Coupe du monde de football masculine se déroulera en 2026, organisée conjointement par les États-Unis, le Canada et le Mexique (projet «United 2026»). Les Américains accueilleront ainsi pour la seconde fois, après 1994, l’évènement le plus populaire de la planète. Pourtant, entre l’Amérique du Nord et le football, c’est loin d’être une histoire d’amour. Supplanté historiquement par le football américain et le base-ball, la notoriété internationale du soccer est surtout le fait des footballeuses, championnes du monde à quatre reprises. Pendant longtemps, l’image du football aux États-Unis a plutôt été associée à la fin de carrière des stars : Pelé, G. Best, J. Cruyff, parmi les plus célèbres, y ont joué. Or, certains observateurs pensent que cela est en train de changer : les stades aux États- Unis se remplissent de plus en plus pour les matchs du championnat national (la MLS), les grands clubs européens viennent toujours plus souvent y faire une tournée estivale, de jeunes joueurs américains sont transférés en Europe, etc. Même si les budgets sont encore loin de ceux des grands clubs européens, de nombreux investisseurs s’intéressent aujourd’hui aux franchises américaines : l’ancienne star du football anglais, D. Beckham, vient par exemple d’acquérir l’équipe de l’Inter Miami. Comme dans le volume 1 consacré au football européen, l’objectif est ici de décrire de manière synthétique l’économie du football (masculin et féminin) en Amérique du Nord, qui demeure très spécifique.

  • What do Happiness Data Mean? Theory and Survey Evidence Article dans une revue:

    What utility notion—e.g. flow/lifetime, self/family-centered—do self-reported well-being (SWB) questions measure? Existing applications make different assumptions regarding the (i) life domains, (ii) time horizons, and (iii) other-regarding preferences captured by SWB data. To obtain relevant evidence, we ask survey respondents what they had in mind regarding (i)–(iii) when answering commonly used—life satisfaction, happiness, ladder—and new SWB questions. We find that respondents’ self-reports differ from researchers’ assumptions and differ across SWB questions and sociodemographic groups. At the same time, simple SWB-question wording tweaks are effective in moving self-reports toward desired interpretations. We outline actionable suggestions for SWB researchers.

  • From Pink-Collar to Lab Coat. Cultural Persistence and Diffusion of Socialist Gender Norms Pré-publication, Document de travail:

    This paper documents the persistence and diffusion of Soviet gender-equal norms, exploiting the 1990’s mass migration from the Former Soviet Union to Israel as a natural experiment. We track educational achievement and choices of an entire cohort, comparing gender gaps among Native students versus immigrants from FSU and other countries. We find evidence of vertical and horizontal diffusion of Soviet norms with respect to tertiary study field choice, especially those directly related to labor market occupations. In both traditionally male-dominated STEM fields and traditionally female “pink collar” jobs, such as education and social work, gender gaps are smallest among FSU immigrants. We show that these specific preferences are not explained by comparative advantages, as measured by early achievement. Finally, we show that among Natives the gender gap in field choice narrows with the presence of FSU immigrants, reflecting a shift in choice patterns of native women shift towards STEM and away from Pink collar study fields.

  • Learning rules of engagement for social exchange within and between groups Article dans une revue:

    Globalizing economies and long-distance trade rely on individuals from different cultural groups to negotiate agreement on what to give and take. In such settings, individuals often lack insight into what interaction partners deem fair and appropriate, potentially seeding misunderstandings, frustration, and conflict. Here, we examine how individuals decipher distinct rules of engagement and adapt their behavior to reach agreements with partners from other cultural groups. Modeling individuals as Bayesian learners with inequality aversion reveals that individuals, in repeated ultimatum bargaining with responders sampled from different groups, can be more generous than needed. While this allows them to reach agreements, it also gives rise to biased beliefs about what is required to reach agreement with members from distinct groups. Preregistered behavioral ( N = 420) and neuroimaging experiments ( N = 49) support model predictions: Seeking equitable agreements can lead to overly generous behavior toward partners from different groups alongside incorrect beliefs about prevailing norms of what is appropriate in groups and cultures other than one’s own.

This raises difficult questions about how to balance these concerns in making policy decisions. In this chapter, we review a number of tools that welfare economics offers for conceptualizing and studying such trade-offs. We argue that social welfare analysis is the most useful method for doing so. We show how concerns for the distributive and other effects of a policy on individual wellbeing can be evaluated using a Social Welfare Function (SWF) and survey some of the main features of such functions. As an illustration, we then use this approach to model and evaluate the implications for social welfare of the adoption of pandemic policies that vary in terms of the stringency of the controls that they impose on individual behaviour. Our model reveals how such evaluations not only are determined by empirical facts but may also depend on key judgments about the relative importance of the different determinants of individual wellbeing (health, income, longevity, and so on) and about the extent to which special concern should be given to the worse-off. In doing so, it illustrates how critical transparent modelling of these concerns is in developing responses to pandemics of this kind.

  • L’Argent du football. Vol. 3, Le foot féminin Ouvrages:

    L’histoire dit qu’un match féminin mythique entre le club des Munitionnettes (du nom des ouvrières fabriquant des munitions) des Dick, Kerr Ladies de Preston et celui des St. Helen’s Ladies, en 1920 le jour du Boxing Day à Liverpool, a attiré 53 000 spectateurs. Un siècle plus tard, à Londres, le 31 juillet 2022, près de 90 000 fans assistent à la finale de l’Euro féminin entre l’Angleterre et l’Allemagne. Mais l’histoire séculaire des femmes et du football est loin d’avoir été un long fleuve tranquille même si le foot féminin est apparu dès le début du jeu à la fin du XIXe siècle. Jusqu’au milieu des années 1960, pour différentes raisons, les femmes ont été « écartées » des terrains un peu partout dans le monde. Aujourd’hui, elles tiennent peut-être leur revanche. Le football féminin fait l’objet de beaucoup d’intérêts, non seulement sportifs, mais aussi idéologiques, politiques et économiques… Le jeu FIFA a même intégré les championnats féminins anglais et français dans sa dernière version de 2023 ! Comparé à son homologue masculin, le foot féminin est encore une très petite « affaire » et le « gender pay gap » entre footballeuses et footballeurs dans les équipes nationales et les sélections internationales est considérable. L’objectif de ce livre est de fournir au lecteur des outils d’analyses pour mieux comprendre l’économie du football féminin.

  • Workplace Democracy, the Bicameral Firm, and Stakeholder Theory Article dans une revue:

    Ferreras’s bicameral governance proposal for the corporation contributes to a recent wave of interest in democratizing the workplace. In this article, I connect this to a related ongoing movement in favor of the stakeholder approach to corporate purpose. I argue that this connection sheds light on, and may provide remedies for, some issues with the bicameral proposal: first, the risk of gridlock between the two parties in the dual governance structure; second, the indeterminacy of good management when shareholder primacy is abandoned. But I also note that shareholder primacy emerged spontaneously from structural features of the economy, so that special protection for the “good” firms is warranted, and that other key limitations of a market economy cannot be alleviated fully by democratizing the firm.

  • Into the Far West? Investigating Health Policy-Makers’ Willingness to Adopt Decrementally Cost-Effective Innovations Using a DCE Approach Pré-publication, Document de travail:

    In a context of increasingly limited resources, a number of strategies, such as the adoption of decrementally cost-effective interventions (d-CEIs), which are both less clinically effective and less costly, could offer potential levers at enhancing both efficiency and equity in healthcare systems. These interventions are located in the SouthWest (S-W) quadrant of the cost-effectiveness plane, and have yet received little attention from researchers or HTA agencies as they are often perceived as per se « unethical » or « unacceptable », hence the reference sometimes made to the S-W quadrant as the ‘Far West’. The purpose of our paper is to investigate policy-makers’ willingness to adopt d-CEIs using a choice experiment. We use a two-stage pairwise DCE survey to elicit (i) preferences for d-CEIs’ attributes in forced choices and (ii) adoption preferences, i.e. the determinants of d-CEIs’ adoption (unforced choices). We investigate the effect (and trade-offs) between three attributes: health loss (very small to significant), reversibility defined as the possibility to switch back to usual care (from possible to hardly possible) and cost-savings (from 5% to 15% of a fixed budget). Such trade-offs are contextualized by using two sensitivity attributes: disease severity (low and moderate) and savings uncertainty (low and high). Our final sample consists of 180 respondents with 46.7% originating from France and the remaining respondents from other EU countries. All attributes’ levels have a significant effect in the two decision stages. The « health loss » attribute dominates in the first stage followed by « reversibility »: we calculate that decision-makers would require 28.3% increase of budget savings to be indifferent between a scenario of small versus significant health losses and 14.5% budget savings to be indifferent between a scenario of possible and hardly possible reversibility. In contrast, the « reversibility » attribute dominates in the second stage suggesting that anticipated regret may play a role in adoption decisions.

  • Linking confidence biases to reinforcement-learning processes. Article dans une revue:

    We systematically misjudge our own performance in simple economic tasks. First, we generally overestimate our ability to make correct choices-a bias called overconfidence. Second, we are more confident in our choices when we seek gains than when we try to avoid losses-a bias we refer to as the valence-induced confidence bias. Strikingly, these two biases are also present in reinforcement-learning (RL) contexts, despite the fact that outcomes are provided trial-by-trial and could, in principle, be used to recalibrate confidence judgments online. How confidence biases emerge and are maintained in reinforcement-learning contexts is thus puzzling and still unaccounted for. To explain this paradox, we propose that confidence biases stem from learning biases, and test this hypothesis using data from multiple experiments, where we concomitantly assessed instrumental choices and confidence judgments, during learning and transfer phases. Our results first show that participants’ choices in both tasks are best accounted for by a reinforcement-learning model featuring context-dependent learning and confirmatory updating. We then demonstrate that the complex, biased pattern of confidence judgments elicited during both tasks can be explained by an overweighting of the learned value of the chosen option in the computation of confidence judgments. We finally show that, consequently, the individual learning model parameters responsible for the learning biases-confirmatory updating and outcome context-dependency-are predictive of the individual metacognitive biases. We conclude suggesting that the metacognitive biases originate from fundamentally biased learning computations.

  • Impact of tariff refinement on the choice between scheduled C‐section and normal delivery: Evidence from France Article dans une revue:

    Studying quasi-experimental data from French hospitals from 2010 to 2013, we test the effects of a substantial diagnosis-related group (DRG) tariff refinement that occurred in 2012, designed to reduce financial risks of French maternity wards. To estimate the resulting DRG incentives with regard to the choice between scheduled C-sections and other modes of child delivery, we predict, based on pre-admission patient characteristics, the probability of each possible child delivery outcome and calculate expected differences in associated tariffs. Using patient-level administrative data, we find that introducing additional severity levels and clinical factors into the reimbursement algorithm had no significant effect on the probability of a scheduled C-section being performed. The results are robust to multiple formulations of DRG financial incentives. Our paper is the first study that focuses on the consequences of a DRG refinement in obstetrics and develops a probabilistic approach suitable for measuring the expected effects of DRG fee incentives in the presence of multiple tariff groups.

  • Economic Insecurity and Health Article dans une revue:

    We here show that individual-level economic insecurity, based on the time profle of economic resources, is detrimental to both physical and mental health in long-run Australian panel data. This relationship is found in panel data, comparing an individual’s change in economic security over time to the changes in her health. A heterogeneity analysis reveals that economic insecurity is par-ticularly detrimental to the health of the most-deprived, those over the age of 30, and men rather than women.

  • Decision-making under risk and ambiguity in adults with Tourette syndrome Article dans une revue:

    Background Tourette syndrome (TS) as well as its most common comorbidities are associated with a higher propensity for risky behaviour in everyday life. However, it is unclear whether this increased risk propensity in real-life contexts translates into a generally increased attitude towards risk. We aimed to assess decision-making under risk and ambiguity based on prospect theory by considering the effects of comorbidities and medication. Methods Fifty-four individuals with TS and 32 healthy controls performed risk and ambiguity decision-making tasks under both gains and losses conditions. Behavioural and computational parameters were evaluated using (i) univariate analysis to determine parameters difference taking independently; (ii) supervised multivariate analysis to evaluate whether our parameters could jointly account for between-group differences (iii) unsupervised multivariate analysis to explore the potential presence of sub-groups. Results Except for general ‘noisier’ (less consistent) decisions in TS, we showed no specific risk-taking behaviour in TS or any relation with tics severity or antipsychotic medication. However, the presence of comorbidities was associated with distortion of decision-making. Specifically, TS with obsessive–compulsive disorder comorbidity was associated with a higher risk-taking profile to increase gain and a higher risk-averse profile to decrease loss. TS with attention-deficit hyperactivity disorder comorbidity was associated with risk-seeking in the ambiguity context to reduce a potential loss. Conclusions Impaired valuation of risk and ambiguity was not related to TS per se . Our findings are important for clinical practice: the involvement of individuals with TS in real-life risky situations may actually rather result from other factors such as psychiatric comorbidities.

    We here investigate the role of risk aversion in COVID‐19 vaccine hesitancy. The theoretical effect is ambiguous, as both COVID‐19 infection and vaccination side‐effects involve probabilistic elements. In large‐scale data covering five European countries, we find that vaccine hesitancy falls with risk aversion, so that COVID‐19 infection is perceived as involving greater risk than is vaccination.

  • Variants of Gender Bias and Sexual-Orientation Discrimination in Career Development Article dans une revue:

    We use a nationally-representative dataset that includes a large sample of sexual-orientation minorities to investigate gender bias and sexual-orientation discrimination in career progression. Our results are consistent with persistent gender bias findings and non-heterosexual identity-based employment discrimination. Our findings are consistent with previous work noting that protective legislation for gay and lesbian sexual identities have increased the cost of discrimination and contribute to the improved socioeconomic status of a substantial number of people in these minority groups. However, these gains have not been shared with other minority groups in the LGB+ community, which still have some of the lowest probabilities of holding managerial jobs, and higher probabilities of appearing in lower socioeconomic classes.

  • The stakeholder corporation and social welfare Article dans une revue:

    The stakeholder (or responsible) firm is defined in this paper as one that maximizes the (weighted or unweighted) sum of the surpluses of its customers and suppliers (including workers). We show that, although this objective is hard to empirically measure, it can be pursued by simple management rules that rely on constrained profit maximization. We find that unconstrained profit maximization gives a competitive edge to ordinary firms, but that stakeholder firms are better for social welfare and internalize several important effects of their activities on society. We also show that long term entry decisions should rely on profit modied by Pigouvian pricing of externalities, incidentally providing a novel justication for the polluter-pays principle.

  • Is There a Proper Scope for Markets? Article dans une revue:

    Debra Satz’s brilliant essay highlights that it is insufficient to study markets in terms of efficiency and potential market failures, as they have deep effects on people and societies. This line of thought could inspire the project of building a general theory of social interactions, in which the specific properties of market transactions would be identified, and their influence on society at large, depending on the surrounding institutions and social structure, could be understood. In this brief essay, personal care provides an example of the complex ramifications of different arrangements for social interactions.

  • The international diffusion of food innovations and the nutrition transition: retrospective longitudinal evidence from country-level data, 1970–2010 Article dans une revue:

    Introduction There is a lack of quantitative evidence on the role of food innovations—new food ingredients and processing techniques—in the nutrition transition. Objective Document the distribution of food innovations across 67 high-income (HIC) and middle-income (MIC) countries between 1970 and 2010, and its association with the nutritional composition of food supply. Methods We used all available data on food patents, as compiled by the European Patent Office, to measure food innovations. We considered innovations directly received by countries from inventors seeking protection in their territories, and those embedded in processed food imports. Food and Agricultural Organization data were used to estimate the associations between international diffusion of food innovations and trends in total food supply and its macronutrient composition, after adjusting for confounding trends in demand-side factors. We identified the role of trade by simulating the changes in average diet due to innovations embedded in food imports. Results Trends in food innovations were positively and significantly associated with changes in daily per capita calorie supply available for human consumption in MIC between 1990 and 2010 (elasticity of 0.027, 95% CI 0.019 to 0.036). Food innovations were positively correlated with the share of animal and free fats in total food supply (elasticities of 0.044, 95% CI 0.030 to 0.058 for MIC between 1970 and 1989 and 0.023, 95% CI 0.003 to 0.043 for HIC between 1990 and 2010). Food innovations were associated with substitutions from complex carbohydrates towards sugars in total food supply for MIC after 1990 (elasticities of −0.037, 95% CI −0.045 to −0.029 for complex carbs, 0.082, 95% CI 0.066 to 0.098 for sugars). For these countries, the trade channel capturing access to innovations through imports of processed food played a key role. Conclusion Policy-makers should consider the impacts of the international diffusion of food innovations in assessing the costs and benefits of international trade regulations.

  • Le travail à distance. Défis, enjeux et limites Ouvrages:

    L’ un des principaux héritages de la pandémie de covid-19 est certainement l’extension des interactions fondées sur les technologies numériques de l’information, en particulier le travail à distance. Dans la plupart des pays, la situation a imposé un recours massif au télétravail pour tous ceux qui le pouvaient. Ce choc a accéléré une évolution ancienne, mais lente et inégale, alimentée par la numérisation de l’économie, permettant à certains de travailler en dehors des locaux de l’entreprise, à domicile ou ailleurs. Le télétravail, au moins partiel, est entré dans les mœurs et pourrait concerner aujourd’hui près de la moitié des emplois dans les pays développés. Après deux cents ans de séparation, le retour au domicile de l’activité économique soulève d’importants défis juridiques. Il est aussi porteur d’interrogations quant aux effets sur le bien-être des travailleurs : liberté accrue ou désocialisation, facteur d’innovation et de coopération renforcée ? Quelles sont les limites à l’extension du travail à distance ? A-t-il touché différemment les hommes et les femmes ? Les travaux réunis dans cet ouvrage, issus de différentes disciplines des sciences humaines et sociales, apportent des éclairages inédits sur ces questions.

  • Taking Back Control? Quasi-Experimental Evidence on the Impact of Retirement on Locus of Control Pré-publication, Document de travail:

    We use nationally representative panel data from Australia to consider the impact of retirement on individual locus of control, a socio-emotional skill that has substantial explanatory power for a broad range of life outcomes. We establish causality via cohort-specific eligibility age for the Australian Age Pension. We show that retirement leads to increased internal locus of control. This greater sense of internal control can explain around one-third and one-fifth of the positive effects of retirement on health and subjective well-being, respectively. The impact of retirement on control beliefs varies along the distribution of locus of control, with the positive influence being most pronounced for men with a relatively high sense of internal control and for women with a relatively high sense of external control. Last, we provide evidence that locus of control is much more malleable at retirement than the other socio-emotional skills of the Big-Five personality traits, risk and time preferences, and trust.

  • Take the Highway? Paved Roads and Well-Being in Africa Pré-publication, Document de travail:

    Public Goods aim to improve individual welfare. We investigate the causal consequences of roads on well-being in 24 African countries, instrumenting paved roads by 19th Century hypothetical lines between major ports and cities. We have data on over 32000 individuals, and consider both their objective and subjective well-being, via access to four basic needs and the subjective evaluation of living conditions respectively. Our instrumental-variable analysis suggests that roads reduce material deprivation, by improving access to basic needs, but that there is no causal relation between the distance to a road and subjective living conditions. The benefit of roads in providing basic needs then seems to be offset by worse outcomes in other domains.

  • A Natural Experiment on Job Insecurity and Fertility in France Article dans une revue:

    Job insecurity can have wide-ranging consequences outside of the labour market. A 1999 rise in the French layoff tax paid by large private firms when they laid off older workers made younger workers less secure; this insecurity reduced their fertility by 3.7 percentage points (with a 95% confidence interval between 0.7 and 6.6 percentage points). Reduced fertility is only found at the intensive margin: job insecurity reduces family size but not the probability of parenthood itself. Our results also suggest negative selection into parenthood, as this fertility effect does not appear for low-income and less-educated workers.

  • Reasoning in attitudes Article dans une revue:

    People reason not only in beliefs, but also in intentions, preferences, and other attitudes. They form preferences from existing preferences, or intentions from existing beliefs and intentions, and so on. This often involves choosing between rival conclusions. Building on Broome (2013) and Dietrich et al. (2019), we present a philosophical and formal analysis of reasoning in attitudes, with or without facing choices in reasoning. We give different accounts of choosing, in terms of a conscious activity or a partly subconscious process. Reasoning in attitudes differs fundamentally from reasoning about attitudes, a form of theoretical reasoning in which one discovers rather than forms attitudes. We show that reasoning in attitudes has standard formal properties (such as monotonicity), but is indeterministic, reflecting choice in reasoning. Like theoretical reasoning, it need not follow logical entailment, but for a more radical reason, namely indeterminism. This makes reasoning in attitudes harder to model logically than theoretical reasoning. But it can be studied abstractly, using indeterministic consequence operators.

    This paper examines the empirical relationship between individuals’ cognitive and non-cognitive abilities and COVID-19 compliance behaviors using cross-country data from the Survey of Health, Ageing and Retirement in Europe (SHARE). We find that both cognitive and non-cognitive skills predict responsible health behaviors during the COVID-19 crisis. Episodic memory is the most important cognitive skill, while conscientiousness and neuroticism are the most significant personality traits. There is also some evidence of a role for an internal locus of control in compliance.

  • Associations between anxiety and the willingness to be exposed to COVID-19 risk among French young adults during the first pandemic wave Article dans une revue:

    The COVID-19 outbreak has generated significant uncertainty about the future, especially for young adults. Health and economic threats, as well as more diffuse concerns about the consequences of COVID-19, can trigger feelings of anxiety, leading individuals to adopt uncertainty-reducing behaviours. We tested whether anxiety was associated with an increase in willingness to be exposed to the risk of COVID-19 infection (WiRE) using an online survey administered to 3,110 French individuals aged between 18 and 35 years old during the first pandemic wave and lockdown period (April 2020). Overall, 56.5% of the sample declared a positive WiRE. A one standard deviation increase in psychological state anxiety raised the WiRE by +3.9 pp (95% CI [+1.6, 6.2]). Unemployment was associated with a higher WiRE (+8.2 percentage points (pp); 95% CI [+0.9, 15.4]). One standard deviation increases in perceived hospitalisation risk and in income (+1160€) were associated with a -4.1 pp (95% CI [-6.2, 2.1]) decrease in the WiRE and +2.7 pp increase (95% CI [+1.1, 4.4]), respectively. Overall, our results suggest that both psychological anxiety and the prospect of economic losses can undermine young adults’ adherence to physical distancing recommendations. Public policies targeting young adults must consider both their economic situation and their mental health, and they must use uncertainty-reducing communication strategies.

  • Income-related health inequality in urban China (1991–2015): The role of homeownership and housing conditions Article dans une revue:

    Unprecedented economic growth has been experienced over the several decades worldwide, but such rapid economic growth wasn’t accompanied by equally-substantial improvement in health, especially health inequalities between the rich and poor. This study examines the role of housing in income-related health inequalities (income-health gradient) in urban China. We here analyze 1991–2015 China Health and Nutrition Survey data to ask how housing affects income-related health inequalities in urban China. We find pro-poor inequalities in self-reported bad health but pro-rich inequalities in objective bad health (general overweight/obesity, central obesity and high blood pressure). Housing conditions serve to reduce the health gradient, especially for objective health. On the contrary, homeownership exacerbates the health gradient. Improving housing conditions thus appears to be an effective way of reducing the income-health gradient in urban China.

  • Public health lessons from the French 2012 soda tax and insights on the modifications enacted in 2018 Article dans une revue:

    In 2016, the World Health Organization officially recommended sugar-sweetened beverage (SSB) taxation as a strategy to reduce purchases, stimulate product reformulation and generate revenues for health-related programmes. Four years before, France had been one of the first countries to tax SSBs. However, the design of this tax was not considered optimal: its rate was flat, low, identical for SSBs and artificially-sweetened drinks containing no added sugars, and its initial public health justification was set aside in favour of budgetary concerns. In 2018, a new taxation scheme was enacted. Integrated in the Social Security Finance Bill, the tax on SSBs is now linearly indexed to the quantity of added sugars in the drink. In this article, we summarize the lessons learnt from the 2012 soda tax and offer insights on the potential public health benefits of the new tax enacted in 2018. A multidimensional framework aimed at gathering evidence about SSB taxation for public health drove our rational so that we address: (1) the soda tax policy-change process; (2) its impact on price and purchases; (3) the consumer receptiveness to the tax and; (4) its legal framework. We also discuss the potential application of the tax to other foods/nutrients.

  • The effects of Uber diffusion on the mental health of drivers Article dans une revue:

    While the spread of digital technologies and the growth of associated atypical forms of work are attracting increasing attention, little is known about the impact of these new forms of work on psychological well-being. This paper examines the effect of Uber diffusion on the mental health of drivers, taking advantage of the rollout of Uber across UK regions. We match individual-level information on health and sociodemographic characteristics from the UK Household Longitudinal Study (Understanding Society) between 2009 and 2019 with data on the diffusion of Uber across the country. We first show that Uber diffusion is positively associated with mental health, as measured by the General Health Questionnaire, in the population group of self-employed drivers. We argue that this positive correlation captures a selection effect (of comparatively healthier individuals into the category of self-employed drivers after Uber entry) and the omission of unobserved factors, rather than a causal effect. Indeed, we do not observe any improvement in mental health for workers who were already self-employed drivers before Uber entry. In parallel with this, among individuals who remained salaried drivers over time, our results suggest there may be a decline in mental health after Uber’s introduction, probably because they feel the competition from Uber drivers.

Certaines peuvent être observées (comme les points avant le licenciement), d’autres restent inobservables. Notre méthode empirique prend en compte les différences observables entre les clubs par appariement exact et corrige des caractéristiques non observées par doubles différences. Nos résultats montrent que les effets d’un changement d’entraîneur sur la performance de l’équipe ne sont pas significatifs, et ce même si l’on tient compte de certaines caractéristiques des coachs.

  • The Value of a Life-Year and the Intuition of Universality Article dans une revue:

    When considering the social valuation of a life-year, there is a conflict between two basic intuitions: on the one hand, the intuition of universality, according to which the value of an additional life-year should be universal, and, as such, should be invariant to the context considered; on the other hand, the intuition of complementarity, according to which the value of a life-year should depend on what this extra-life-year allows for, and, hence, on the quality of that life-year, because the quantity of life and the quality of life are complement to each other. This paper proposes three distinct accounts of the intuition of universality, and shows that those accounts either conflict with a basic monotonicity property, or lead to indifference with respect to how life-years are distributed within the population. Those results support the abandon of the intuition of universality. But abandoning the intuition of universality does not prevent a social evaluator from giving priority, when allocating life-years, to individuals with the lowest quality of life.

Policy responses are measured by the Stringency Index and the Economic Support Index from the Blavatnik School of Government. Stringency is systematically associated with lower life satisfaction, controlling for the intensity of the pandemic itself. This stringency effect is larger for women, those with weak ties to the labor market, and in richer households. The effect of the Economic Support is never statistically different from zero.

  • Comparing Voting Methods : 2016 US Presidential Election Article dans une revue:

    This paper presents data from a survey leading up to the 2016 US presidential elections. Participants were asked their opinions about the candidates and were also asked to vote according to three alternative voting rules, in addition to plurality: approval voting, range voting, and instant runoff voting. The participants were split into two groups, one facing a set of four candidates (Clinton, Trump, Johnson, and Stein) and the other a set of nine candidates (the previous four plus Sanders, Cruz, McMullin, Bloomberg, and Castle). The paper studies three issues: (1) How do US voters use these alternative rules? (2) What kinds of candidates, in terms of individual preferences, are favored by which rule? (3) Which rules empirically satisfy the independence of eliminated alternatives? Our results provide evidence that, according to all standard criterion computed on individual preferences, be there utilitarian or of the Condorcet type, the same candidate (Sanders) wins, and that evaluative voting rules such as approval voting and range voting might lead to this outcome, contrary to direct plurality and instant runoff voting (that elects Clinton) and to the official voting rule (that elected Trump).

  • Well‐being during the Great Recession: new evidence from a measure of multi‐dimensional living standards with heterogeneous preferences* Article dans une revue:

    We develop a distribution-adjusted welfare measure that aggregates income, unemployment, and longevity using individual weights that reflect heterogeneous preferences. The measure is implemented for 28 OECD countries for 2008–2013 to gauge the welfare effects of the Great Recession. Estimated shadow prices of one percentage point of unemployment and one year of longevity average 3.1 percent and 5.7 percent of household income, respectively. We find that the rate of GDP growth poorly reflects the social cost of the Great Recession. On average, GDP per capita stagnated across OECD countries between 2008 and 2013 while living standards of poor households fell by 5.3 percent annually.

  • Values, Volumes, and Price-Volume Decompositions: On Some Issues Raised (Again) by the Health Crisis Article dans une revue:

    The health crisis has underscored the need for national accounts that can track the activity and financial situations of various groups of economic agents as quickly as possible. It also raises several questions about how real GDP aggregates quantities of heterogenous goods and services that meet very different needs whose relative priorities have been affected by the crisis, at least temporarily. We focus on two aspects of this question: the theoretical properties of aggregation by chaining at market prices for the market share of GDP and the joint problems of measurement and significance of the aggregate for its non-market components. Beyond the short-term shock, the crisis provides an opportunity to revisit some substantive issues regarding the interpretation of output and real growth indicators, issues that the post-crisis period should continue to fuel.

  • A new puzzle in the social evaluation of risk Article dans une revue:

    We highlight a new paradox for the social evaluation of risk that bears on the evaluation of individual well-being rather than social welfare, but has serious implications for social evaluation. The paradox consists in a tension between rationality, respect for individual preferences, and a principle of informational parsimony that excludes individual risk attitudes from the assessment of riskless situations. No evaluation criterion can satisfy these three principles. This impossibility result has implications for the evaluation of social welfare under risk, especially when the preferences of some individuals are not known. It generalizes existing impossibility results, while relying on very weak principles of social rationality and respect for individual preferences. We explore the possibilities opened by weakening each of our three principles and discuss the advantages and drawbacks of these different routes.

  • Des citoyennes délibératives et des citoyens délibératifs : La Convention citoyenne pour le climat face à la délibération Article dans une revue:

    Le processus de recrutement (le « tirage au sort ») d’un mini-public conduit à sélectionner des volontaires motivé·es et disponibles pour participer à l’assemblée. Cependant, leurs dispositions pour la délibération ne se révèlent qu’en situation et dépendent largement du déroulement même du processus délibératif. L’analyse des réponses des volontaires participant à la Convention citoyenne pour le climat à des questionnaires portant sur la qualité délibérative des échanges, ainsi que leur comparaison avec celles données par les participant·es aux conférences citoyennes régionales du Grand débat national (France, 2019) et du G1000 (Belgique, 2011), permettent de saisir l’expression de dispositions relationnelles dans les interactions qui font d’une situation délibérative une expérience partagée. Nous employons l’expression « citoyennes délibératives et citoyens délibératifs » pour qualifier les interactions entre dispositions individuelles et dispositif délibératif, constitutives de l’expérience partagée. L’écoute et le respect entre participant·es, la sincérité des prises de parole et leur orientation vers le bien commun, et le goût pour l’expression du désaccord politique en face à face forment la confiance des citoyennes délibératives et des citoyens délibératifs dans leur capacité collective à produire des propositions efficaces et justes. Un programme comparatif international permettrait de documenter leur expérience en saisissant plus finement les dispositions individuelles favorables à la délibération, leur formation et leur dynamique, en interrogeant les comportements qui les manifestent selon les motifs de participation.

  • La Coupe du monde de football : la bonne affaire ? Article dans une revue:

    Le « joyau » de la couronne de la FIFA et son principal « actif » demeure la Coupe du monde. Créée en 1928, elle a lieu tous les quatre ans depuis le tournoi de 1930 organisé et remporté par l’Uruguay parmi treize prétendants. Le Qatar accueillera 32 équipes, mais plus de 200 formations appartenant aux six confédérations continentales ont participé aux phases éliminatoires. Après la Seconde Guerre mondiale, la Coupe du monde va connaitre une très forte croissance en termes de diffusion (à partir de 1966), de notoriété sportive, d’enjeu social et d’activité économique (surtout à partir des années 1970). La compétition est devenue un évènement global, bénéficiant d’une diffusion planétaire. La Coupe du monde est non seulement devenue la principale source de financement de la FIFA, mais un grand nombre de fédérations nationales et de gouvernements souhaitent organiser cet événement pour bénéficier d’éventuelles retombées en matière sociales et économiques.

  • Jury Theorems Article dans une revue:

    Jury theorems are mathematical theorems about the ability of collectives to make correct decisions. Several jury theorems carry the optimistic message that, in suitable circumstances, “crowds are wise”: many individuals together (using, for instance, majority voting) tend to make good decisions, outperforming fewer or just one individual. Jury theorems form the technical core of epistemic arguments for democracy, and provide probabilistic tools for reasoning about the epistemic quality of collective decisions. The popularity of jury theorems spans across various disciplines such as economics, political science, philosophy, and computer science. This entry reviews and critically assesses a variety of jury theorems. It first discusses Condorcet’s initial jury theorem, and then progressively introduces jury theorems with more appropriate premises and conclusions. It explains the philosophical foundations, and relates jury theorems to diversity, deliberation, shared evidence, shared perspectives, and other phenomena. It finally connects jury theorems to their historical background and to democratic theory, social epistemology, and social choice theory.

  • Cost-effectiveness of strategies to control the spread of carbapenemase-producing Enterobacterales in hospitals: a modelling study Article dans une revue:

    Background Spread of resistant bacteria causes severe morbidity and mortality. Stringent control measures can be expensive and disrupt hospital organization. In the present study, we assessed the effectiveness and cost-effectiveness of control strategies to prevent the spread of Carbapenemase-producing Enterobacterales (CPE) in a general hospital ward (GW). Methods A dynamic, stochastic model simulated the transmission of CPE by the hands of healthcare workers (HCWs) and the environment in a hypothetical 25-bed GW. Input parameters were based on published data; we assumed the prevalence at admission of 0.1%. 12 strategies were compared to the baseline (no control) and combined different prevention and control interventions: targeted or universal screening at admission (TS or US), contact precautions (CP), isolation in a single room, dedicated nursing staff (DNS) for carriers and weekly screening of contact patients (WSC). Time horizon was one year. Outcomes were the number of CPE acquisitions, costs, and incremental cost-effectiveness ratios (ICER). A hospital perspective was adopted to estimate costs, which included laboratory costs, single room, contact precautions, staff time, i.e. infection control nurse and/or dedicated nursing staff, and lost bed-days due to prolonged hospital stay of identified carriers. The model was calibrated on actual datasets. Sensitivity analyses were performed. Results The baseline scenario resulted in 0.93 CPE acquisitions/1000 admissions and costs 32,050 €/1000 admissions. All control strategies increased costs and improved the outcome. The efficiency frontier was represented by: (1) TS with DNS at a 17,407 €/avoided CPE case, (2) TS + DNS + WSC at a 30,700 €/avoided CPE case and (3) US + DNS + WSC at 181,472 €/avoided CPE case. Other strategies were dominated. Sensitivity analyses showed that TS + CP might be cost-effective if CPE carriers are identified upon admission or if the cases have a short hospital stay. However, CP were effective only when high level of compliance with hand hygiene was obtained. Conclusions Targeted screening at admission combined with DNS for identified CPE carriers with or without weekly screening were the most cost-effective options to limit the spread of CPE. These results support current recommendations from several high-income countries.

  • Premature deaths, accidental bequests, and fairness* Article dans une revue:

    While little agreement exists regarding the taxation of bequests in general, there is a widely held view that accidental bequests should be subjected to a confiscatory tax. We reexamine the optimal taxation of accidental bequests by introducing a concern for compensating individuals for a premature death. Assuming that individuals care about what they leave to their offspring, we show that, whereas the 100 % tax view holds under the utilitarian criterion, the ex post egalitarian criterion (giving priority to the worst-off ex post) implies subsidizing accidental bequests so as to compensate the short-lived. In a second-best setting, compensating the short-lived justifies taxing total bequests at a rate increasing with the age of the deceased. Finally, when the model is extended to an intergenerational setting, accidental bequests cannot be used as a redistributive tool anymore, so that ex post egalitarianism rejoins the 100 % tax view.

  • Categorical versus graded beliefs Article dans une revue:

    This essay discusses the difficulty to reconcile two paradigms about beliefs: the binary or categorical paradigm of yes/no beliefs and the probabilistic paradigm of degrees of belief. The possibility for someone to hold beliefs of both types simultaneously is challenged by the lottery paradox, and more recently by a general impossibility theorem by Dietrich and List. The nature, relevance, and implications of the tension are explained and assessed.

  • Subjective Return Expectations, Perceptions, and Portfolio Choice Article dans une revue:

    Exploiting a representative sample of the French population by age, wealth, and asset classes, we document novel facts about their expectations and perceptions of stock market returns. Both expectations and perceptions of returns are very dispersed, significantly lower than their data counterparts, and a substantial portion of the variation in the former is explained by dispersion in the latter. Consistent with portfolio choice models under incomplete information, a conditional risk-return trade-off explains the intensive margin, while at the extensive margin, only expected returns matter. Despite accounting for survey measurement error in subjective return expectations, ’muted sensitivities’ at both portfolio choice margins obtain, getting consistently (i) bigger when excluding informed non-participants, and (ii) smaller, for inertial and professionally delegated portfolios.

  • The impassable gap between experiential and symbolic values Article dans une revue:

    To choose between options of different natures, standard decision models presume that a single representational system ultimately indexes their subjective value on a common scale, regardless of how they are constructed. To challenge this assumption, we systematically investigated hybrid decisions between experiential options, whose value is built from past outcomes experience, and symbolic options which describe probabilistic outcomes. We show that participants’ choices exhibited a pattern consistent with a systematic neglect of the experiential values. This normatively irrational decision strategy held after accounting for alternative explanations, and persisted when it bore an economics cost. Overall, our results demonstrate that experiential and symbolic values are not symmetrically considered in hybrid decisions, suggesting that they are not commensurable and recruit different representational systems which may be assigned different priority levels in the decision process. These findings challenge the dominant models commonly used in value-based decision-making research.

  • L’évaluation socioéconomique des effets de santé des projets d’investissement public. Rapport du groupe de travail Rapport:

    Pour une bonne allocation des ressources de la puissance publique, l’objectif de l’évaluation socioéconomique est d’apprécier, avec des critères transparents, l’utilité et l’intérêt collectif de projets d’investissement public ou de politiques publiques, y compris vis-à-vis de la protection de la santé des personnes dont l’enjeu est d’une importance particulière. Pourtant, la prise en compte des effets sur la santé dans les évaluations est souvent réduite à des tentatives isolées et exploratoires. Le manque d’outils ou de valeurs monétaires permettant d’évaluer et de valoriser les effets relatifs à la santé des personnes – on parlera d’« effets de santé » dans ce rapport pour couvrir à la fois les maladies et la qualité de vie, terme utilisé en économie de la santé1 – apparaît comme l’une des raisons de leur absence des évaluations socioéconomiques ex ante, ce qui revient finalement à considérer qu’ils sont nuls lors de la prise de décision. Dans ce contexte, mais également pour encourager le transfert des avancées méthodologiques du secteur de la santé (tel le recours à un indicateur synthétique de santé) vers d’autres secteurs et rendre explicite un coût de l’inaction, le Comité d’experts des méthodes d’évaluation socioéconomique, installé par France Stratégie et le Secrétariat général pour l’investissement, a lancé un groupe de travail sur l’évaluation socioéconomique des effets de santé des projets d’investissement public. Il a confié la présidence de ce groupe à Benoît Dervaux, économiste de la santé, maître de conférence-praticien hospitalier de santé publique à l’université de Lille et au Centre hospitalier universitaire de Lille (UMR 1167 RID-AGE), et Lise Rochaix, professeure agrégée des universités en sciences économiques à l’université de Paris 1 Panthéon-Sorbonne, affiliée à l’École d’économie de Paris et responsable scientifique de la chaire Hospinnomics, EEP et AP-HP. Ce groupe a cherché à établir une méthodologie d’estimation des coûts tangibles et intangibles des effets de santé qui puisse être appliquée à différents secteurs, dont quatre en particulier : dommages psychologiques des inondations, bénéfices de bénéfices de santé de l’activité physique dans l’espace public.

  • Leveraging the Honor Code: Public Goods Contributions under Oath Article dans une revue:

    Public good games are at the core of many environmental challenges. In such social dilemmas, a large share of people endorse the norm of reciprocity. A growing literature complements this finding with the observation that many players exhibit a self-serving bias in reciprocation: « weak reciprocators » increase their contributions as a function of the effort level of the other players, but less than proportionally. In this paper, we build upon a growing literature on truth-telling to argue that weak reciprocity might be best conceived not as a preference, but rather as a symptom of an internal trade-off at the player level between (i) the truthful revelation of their private reciprocal preference, and (ii) the economic incentives they face (which foster free-riding). In truth-telling experiments, many players misrepresent private information when this is to their material benefit, but to a significantly lesser extent than what would be expected based on the profit-maximizing strategy. We apply this behavioral insight to strategic situations, and test whether the preference revelation properties of the classic voluntary contribution game can be improved by offering players the possibility to sign a classic truth-telling oath. Our results suggest that the honesty oath helps increase cooperation (by 33% in our experiment). Subjects under oath contribute in a way which is more consistent with (i) the contribution they expect from the other players and (ii) their normative views about the right contribution level. As a result, the distribution of social types elicited under oath differs from the one observed in the baseline: some free-riders, and many weak reciprocators, now behave as pure reciprocators.

  • Conditions of existence and subjective perceptions of retirement: quantitative evidence from France Article dans une revue:

    This article explores subjective perceptions of retirement in France, using original quantitative data on the customers of a not-for-profit insurance company. The sample contains individuals aged 40–84, who are either in the labour force (N = 923) or retired (N = 705). Perceptions of retirement are measured using closed questions on views of the retirement transition (these views can be positive, negative or neutral) and definitions of retirement (retirement can be interpreted as a period of freedom, boredom, greater risk of precariousness, etc.). Using a number of different social indicators, we examine whether differences in social conditions translate into heterogeneous perceptions. We also investigate whether social differences in perceptions fade away with increasing age. Both working-age individuals and retirees generally have a positive view of the retirement transition and often define retirement as a period of freedom. Perceptions of retirement are shaped by social conditions: a higher level of education and income, greater wealth, better health and stronger social involvement go hand in hand with rosier perceptions. Moreover, we uncover a strengthening of this social gradient with increasing age. Finally, perceptions are positively correlated with satisfaction in various domains, for retirees.

  • La discrimination à l’embauche selon le sexe Rapport:

    Les inégalités sur le marché du travail entre les femmes et les hommes sont importantes : la participation des femmes reste plus faible que celle des hommes, leurs rémunérations sont inférieures en moyenne et elles connaissent des trajectoires professionnelles moins ascendantes que les hommes. La contribution des conditions d’accès à l’emploi à ces inégalités professionnelles reste encore mal connue. Les résultats issus d’études par correspondance (testings) en France suggèrent une discrimination à l’embauche à l’encontre des femmes limitée en moyenne mais qui varie selon les contextes étudiés. Le testing mené par l’Institut des politiques publiques et ISM Corum sous l’égide de la Dares permet de mesurer la discrimination à l’embauche selon le sexe dans des métiers qui varient selon leur niveau de qualification, de féminisation et de difficultés de recrutement. Cette vaste expérimentation a consisté à envoyer des CV fictifs en réponse à plusieurs milliers d’offres d’emploi dans onze métiers distincts en faisant varier les identités sur les candidatures. Ce rapport présente le protocole expérimental mis en œuvre ainsi que les principaux résultats de cette expérimentation.

  • Homo moralis goes to the voting booth: coordination and information aggregation Article dans une revue:

    This paper revisits two classical problems in the theory of voting—viz. the divided majority problem and the strategic revelation of information—in the light of evolutionarily founded partial Kantian morality. It is shown that, compared to electorates consisting of purely self-interested voters, such Kantian morality helps voters solve coordination problems and improves the information aggregation properties of equilibria, even for modest levels of morality.

  • The Joneses in Japan: income comparisons and financial satisfaction Article dans une revue:

    This paper uses relatively large-scale internet survey data from Japan to analyse income comparisons and income satisfaction. In contrast to the vast majority of empirical work in the area of subjective well-being, we are able to measure both the direction (to whom?) and intensity (how much?) dimensions of income comparisons. Relative to Europeans, the Japanese compare more to friends and less to colleagues, and compare their incomes more. The relationship between satisfaction and reference-group income is negative and more negative for those who say that they compare their incomes more. Our main finding concerns the measure of the relevant reference-group income. It is common in non-experimental work to calculate “others’ income” as some conditional or unconditional cell-mean, with the cells being defined by neighbourhood, workplace or demographic type. We show that two such cell-mean measures (one from within the dataset, the other matched in from external sources) fit the well-being data worse than does a simple self-reported measure of what relevant others earn. The self-reported measure of others’ income would arguably make a useful addition to many existing surveys.

  • La maîtrise est associée au statut pondéral, à la prise alimentaire, au grignotage et aux symptômes des troubles de l’alimentation dans l’étude de cohorte NutriNet-Santé Article dans une revue:

    La maîtrise est une ressource psychologique définie comme la mesure dans laquelle les individus perçoivent qu’ils ont le contrôle des circonstances importantes de leur vie. Bien que la maîtrise ait été associée à divers résultats en matière de santé physique et psychologique, les études évaluant sa relation avec le statut pondéral et le comportement alimentaire font défaut. L’objectif de cette étude transversale était d’évaluer la relation entre la maîtrise et le statut pondéral, la prise alimentaire, le grignotage et les symptômes de troubles alimentaires dans l’étude de cohorte NutriNet-Santé. La maîtrise a été mesurée à l’aide de l’échelle de maîtrise de Pearlin (PMS) chez 32 588 adultes (77,45 % de femmes), dont l’âge moyen était de 50,04 (14,53) ans. L’âge moyen était de 50,04 (14,53) ans. La taille et le poids ont été autodéclarés. La qualité globale du régime alimentaire et la consommation de groupes d’aliments ont été évaluées à l’aide de ≥3 relevés alimentaires autodéclarés sur 24 heures (fourchette : 3-27). Le grignotage a été évalué à l’aide d’une question ad hoc. Les symptômes de la dysfonction érectile ont été évalués à l’aide du questionnaire « Sick-Control-One-Fat-Food » (SCOFF). Des analyses de régression linéaire et logistique ont été effectuées pour évaluer la relation entre la maîtrise et le statut pondéral, la prise alimentaire, le grignotage et les symptômes de dysfonctionnement érectile, en tenant compte des caractéristiques sociodémographiques et du mode de vie. Les femmes ayant un niveau de maîtrise plus élevé étaient moins susceptibles d’être en sous-poids (OR : 0,88 ; 95%CI : 0,84, 0,93), en surpoids [OR : 0,94 (0,91, 0,97)], ou obèses [classe I : OR : 0,86 (0,82, 0,90) ; classe II : OR : 0,76 (0,71, 0,82) ; classe III : OR : 0,77 (0,69, 0,86)]. Les hommes ayant un niveau de maîtrise plus élevé étaient moins susceptibles d’être obèses [classe III : OR : 0,75 (0,57, 0,99)]. La maîtrise était associée à une meilleure qualité de l’alimentation en général, à une plus grande consommation de fruits et légumes, de produits de la mer, d’aliments complets, de légumineuses, de fruits oléagineux non salés et de boissons alcoolisées, et à une plus faible consommation de viande et de volaille, de produits laitiers, de produits sucrés et gras, de desserts à base de lait et de boissons sucrées. La maîtrise était également associée à une moindre fréquence de grignotage [OR : 0,89 (0,86, 0,91)] et à une diminution des symptômes de dysfonctionnement érectile [OR : 0,73 (0,71, 0,75)]. La maîtrise étant associée à un comportement alimentaire favorable et au statut pondéral, cibler la maîtrise pourrait être une approche prometteuse pour promouvoir des comportements sains.

  • L’épargne-retraite : deux décennies de comportements des ménages français (1997-2018) Article dans une revue:

    Nous examinons les comportements d’épargne et de placement des ménages français sur longue période, à travers cinq vagues de l’enquête Patrimoine de l’Insee, qui couvrent deux décennies (1997-2018). Les enquêtes, conduites en 1997-1998, 2003-2004, 2009- 2010, 2014-2015 et 2017-2018, interrogent chacune entre 9 000 et 15 000 ménages de façon détaillée sur leur détention d’actifs financiers, immobiliers et professionnels, sur leur endettement et sur leurs revenus. Elles intègrent également des questions sur les caractéristiques sociodémographiques et le parcours professionnel des membres du ménage ; la dernière vague d’enquête (2017-2018) a ainsi été renommée « Histoire de vie et Patrimoine ». Lorsque cela était nécessaire, les variables sociodémographiques et patrimoniales ont été harmonisées au travers des cinq vagues d’enquête (voir annexe 1). Sur l’ensemble de la période couverte (1997-2018), la détention de produits d’épargne-retraite a été affectée par les réformes des régimes de retraite à partir de 1993, mais également, à partir de 2003, par de nombreux changements législatifs concernant l’épargne-retraite, les pouvoirs publics ayant accompagné la baisse future des droits à pension d’incitations à l’épargne individuelle (Mitchell et al., 2003). L’évolution des détentions d’épargne-retraite dépend également des rendements relatifs des produits et du rendement espéré de ces produits sur le cycle de vie (COR, 2021b ; Hamayon, Legros & Pradat, 2020). Enfin, l’évolution des revenus et la crise financière de 2007-2008 ont modifié les intentions des ménages concernant l’épargne.

  • Co-construction” in Deliberative Democracy: Lessons from the French Citizens’ Convention for Climate Article dans une revue:

    Launched in 2019, the French Citizens’ Convention for Climate (CCC) tasked 150 randomly-chosen citizens with proposing fair and effective measures to fight climate change. This was to be fulfilled through an “innovative co-construction procedure,” involving some unspecified external input alongside that from the citizens. Did inputs from the steering bodies undermine the citizens’ accountability for the output? Did co-construction help the output resonate with the general public, as is expected from a citizens’ assembly? To answer these questions, we build on our unique experience in observing the CCC proceedings and documenting them with qualitative and quantitative data. We find that the steering bodies’ input, albeit significant, did not impair the citizens’ agency, creativity and freedom of choice. While succeeding in creating consensus among the citizens who were involved, this co-constructive approach however failed to generate significant support among the broader public. These results call for a strengthening of the commitment structure that determines how follow-up on the proposals from a citizens’ assembly should be conducted.

  • Patrimoine et âge envisagé de départ à la retraite Article dans une revue:

    En France, les départs à la retraite sont fortement marqués par une « norme sociale » puisqu’une très large majorité des personnes liquident leurs droits au taux plein, que ce soit par la durée de cotisation ou par l’âge légal. Pour autant, le niveau de vie, les conditions de travail, la santé et les incitations financières sont susceptibles d’influencer ces départs. Nous étudions ici les liens entre âge de départ à la retraite et montant du patrimoine. Plus précisément, nous testons l’existence d’un éventuel effet richesse en évaluant les effets du patrimoine du ménage sur l’âge envisagé de départ à la retraite par les individus. Pour cela, nous mobilisons l’enquête de suivi « Histoire de vie et patrimoine » 2014-2015 de l’Insee. Deux conclusions principales sont tirées de l’analyse économétrique. La première concerne les ménages endettés (sur leur logement principal ou pour leur entreprise), qui envisagent de se retirer plus tard du marché du travail. La seconde montre que, quelle que soit la définition de la richesse (brute, nette, financière), on anticipe une retraite plus tardive si l’on est relativement pauvre ou si l’on est relativement riche : l’effet richesse sur l’âge envisagé de départ à la retraite n’est donc pas linéaire. Ces effets « retard » aux extrêmes sont évidemment de nature différente : sans doute pour des raisons de niveau de vie pour les plus pauvres ; vraisemblablement pour d’autres motifs pour les plus riches (intérêt au travail, altruisme intergénérationnel, etc.).

  • Inequities in cancer drug development in terms of unmet medical need Article dans une revue:

    This study measures inequality and inequity in the distribution of clinical trials on cancer drug development between 1996 and 2016, comparing the number of clinical trials with cancer need, proxied by prevalence, incidence, or survival rates for both rare and non-rare cancers. We leverage a unique global database of clinical trials activity and costs between 1996 and 2016, constructed for 227 different cancer types to measure for rare and non-rare cancers: i) inequalities and inequity of clinical trial activity, considering all trials as well as split by R&D stage; ii) inequalities and inequity in R&D investment proxied by trial enrollment and duration; iii) evolution of inequity over time. Inequalities are measured with concentration curves and indices and inequities measured with the health inequity index. We find four important results. First, we show pro-low need inequity across cancer types for both rare and non-rare cancers, for all need proxies. Second, we show inequity differs across R&D stages and between rare and non-rare cancers. The distribution of clinical trials for non-rare cancers disproportionately favors low-need non-rare cancers from earlier to later stages of R&D, whilst for rare cancers this only occurs in Phase 2 trials. Third, inequity analyses in R&D investment show that only trial enrollment for rare cancers and trial duration for non-rare cancers are disproportionately concentrated among low-need cancers. Finally, while pro-low need inequity has persisted between 1996 and 2016 for non-rare cancers, it has faded for rare cancers post-EU orphan drugs’ legislation.

  • The computational roots of positivity and confirmation biases in reinforcement learning Article dans une revue:

    Humans do not integrate new information objectively: outcomes carrying a positive affective value and evidence confirming one’s own prior belief are overweighed. Until recently, theoretical and empirical accounts of the positivity and confirmation biases assumed them to be specific to ‘high-level’ belief updates. We present evidence against this account. Learning rates in reinforcement learning (RL) tasks, estimated across different contexts and species, generally present the same characteristic asymmetry, suggesting that belief and value updating processes share key computational principles and distortions. This bias generates over-optimistic expectations about the probability of making the right choices and, consequently, generates over-optimistic reward expectations. We discuss the normative and neurobiological roots of these RL biases and their position within the greater picture of behavioral decision-making theories.

  • Climate change increases resource-constrained international immobility Article dans une revue:

    Migration is a widely used adaptation strategy to climate change impacts. Yet resource constraints caused by such impacts may limit the ability to migrate, thereby leading to immobility. Here we provide a quantitative, global analysis of reduced international mobility due to resource deprivation caused by climate change. We incorporate both migration dynamics and within-region income distributions in an integrated assessment model. We show that climate change induces decreases in emigration of lowest-income levels by over 10% in 2100 for medium development and climate scenarios compared with no climate change and by up to 35% for more pessimistic scenarios including catastrophic damages. This effect would leave resource-constrained populations extremely vulnerable to both subsequent climate change impacts and increased poverty.

    Comment les Français conçoivent-ils la répartition des revenus dans la société et leur propre place dans la hiérarchie sociale ? Et quelle est la prévalence des opinions dites « populistes » ? La dernière vague de l’enquête ISSP (2019) montre que ces différentes perceptions sont généralement cohérentes entre elles, à deux exceptions près : (1) la plupart des Français interrogés pensent appartenir à la classe moyenne, mais se font une idée très inégalitaire de la société française à l’image d’une pyramide, c’est-à-dire une grande proportion de pauvres et des effectifs de plus en plus faibles à mesure que l’on s’élève dans l’échelle des positions. (2) Ces différentes opinions des Français semblent dissociées de leur propre niveau de revenu.

  • Adopting Telework. The causal impact of working from home on subjective wellbeing. Pré-publication, Document de travail:

    We study the impact of work from home on subjective wellbeing during the Covid period, where self-selection of individuals into telework is ruled out, at least part of the time, by stay-at-home orders. We use a difference-in-difference approach with two-way fixed-effects and identify the specific impact of switching to telecommuting, separately from any other confounding factor. In particular, our identification strategy avoids the influence of inter-personal heterogeneity by exploiting the multiple entries into telework, by the same individuals, at different times. On average over the period, switching to work from home -especially full-time, worsens mental health. We also distinguish a positive but imprecisely measured impact of part-time telework on life satisfaction. However, this hides a dynamic evolution, whereby the initial deterioration gives place to an adaptation process after a couple of months. We also uncover a particularly pronounced fall in subjective wellbeing of women with children’s subjective, especially in the first months; this could be associated with home-schooling.

  • Metacognition and the effect of incentive motivation in two compulsive disorders: Gambling disorder and obsessive–compulsive disorder Article dans une revue:

    Aims Compulsivity is a common phenotype among psychiatric disorders, such as obsessive–compulsive disorder (OCD) and gambling disorder (GD). Deficiencies in metacognition, such as the inability to estimate one’s performance via confidence judgments could contribute to pathological decision‐making. Earlier research has shown that patients with OCD exhibit underconfidence, while patients with GD exhibit overconfidence. Moreover, it is known that motivational states (e.g. monetary incentives) influence metacognition, with gain (respectively loss) prospects increasing (respectively decreasing) confidence. Here, we reasoned that OCD and GD symptoms might correspond to an exacerbation of this interaction between metacognition and motivation. Methods We hypothesized GD’s overconfidence to be exaggerated during gain prospects, while OCD’s underconfidence to be worsened in loss context, which we expected to see represented in ventromedial prefrontal cortex (VMPFC) blood‐oxygen‐level‐dependent activity. We tested those hypotheses in a task‐based functional magnetic resonance imaging (fMRI) design (27 patients with GD, 28 patients with OCD, 55 controls). The trial is registered in the Dutch Trial Register (NL6171). Results We showed increased confidence for patients with GD versus patients with OCD, which could partly be explained by sex and IQ. Although our primary analyses did not support the hypothesized interaction between incentives and groups, exploratory analyses did show increased confidence in patients with GD specifically in gain context. fMRI analyses confirmed a central role for VMPFC in the processing of confidence and incentives, but no differences between the groups. Conclusion Patients with OCD and those with GD reside at opposite ends of the confidence spectrum, while no interaction with incentives was found, nor group differences in neuronal processing of confidence.

  • Economic insecurity and political preferences Article dans une revue:

    Economic insecurity has attracted growing attention, but there is no consensus as to its definition. We characterize a class of individual economic-insecurity measures based on the time profile of economic resources. We apply this economic-insecurity measure to political-preference data in the USA, UK, and Germany. Conditional on current economic resources, economic insecurity is associated with both greater political participation (support for a party or the intention to vote) and more support for conservative parties. In particular, economic insecurity predicts greater support for both Donald Trump before the 2016 US Presidential election and the UK leaving the European Union in the 2016 Brexit referendum.

  • L’Argent du football. Vol. 1, L’Europe Ouvrages:

    Si la pandémie à la Covid-19 a eu des conséquences importantes sur l’économie du football, la riche actualité (économique) de ce sport va bien au-delà de la crise sanitaire. Au niveau européen, l’annonce de la création (avortée) de la Super League en avril 2021 a provoqué un petit séisme et suscité l’ire des supporters. L’atonie du marché des transferts sur les deux dernières saisons a mis en difficulté les clubs dont le modèle économique repose sur le trading joueurs. Les problèmes financiers de certains gros clubs européens ont incité l’UEFA à revoir le fair-play financier avec l’introduction d’un « salary cap ». L’arrivée du fonds souverain saoudien à Newcastle en octobre 2021 a bousculé les clubs de Premier League et l’entrée des fonds d’investissements dans le football, non seulement dans les clubs, mais aussi au niveau des ligues, interroge. Du côté français, la période a été marquée par la défection du diffuseur Mediapro, mais le football a pu se réjouir du transfert de Lionel Messi au PSG à l’été 2021. L’hypothèse soutenue dans ce livre est que le football entre dans une nouvelle ère : l’hypermodernité. On en donne les arguments et les outils. En particulier, les thèmes des inégalités et de la croissance, comme d’ailleurs dans la société, sont centraux pour envisager l’avenir du football, notamment l’émergence de la Super League européenne.

  • La Mobilité sociale perçue par les Français Rapport:

    Les Français se représentent leur société comme très inégalitaire mais, comme la plupart des Européens, s’y voient occuper une place de niveau intermédiaire – même si, aux côtés des Russes, des Italiens et des Japonais, ils sont plus nombreux que les autres à se voir sur les niveaux inférieurs de l’échelle sociale. Mais au-delà de cette position statique, comment perçoivent-ils leur mobilité sociale ? La France fait partie des pays dont les habitants sont les plus nombreux en moyenne à penser avoir progressé par rapport à la position sociale de leurs parents – comme l’Allemagne, la Finlande et Israël par exemple, et à l’opposé de la Russie et du Japon. Pour ce concerne l’évolution future de leur position relative dans la société, la majorité des Français anticipe une certaine stabilité. Ces perceptions dépendent aussi du revenu des individus : jusqu’aux deux quintiles les plus riches, tous anticipent une mobilité intra et inter-générationnelle ascendante. Ceux qui voient la société comme un sapin ou une toupie (peu de pauvres) sont beaucoup plus optimistes quant à leur propre trajectoire. Ceux qui l’imaginent comme une pyramide (inégalitaire) perçoivent une mobilité intergénérationnelle- mais pas intragénérationnelle- ascendante. Enfin, en ce qui concerne le lien avec le positionnement politique, c’est à droite que la mobilité ascendante est perçue comme la plus forte. Au total, les Français se montrent assez optimistes quant à leur trajectoire de mobilité sociale, surtout par rapport à leurs parents, et l’image générale que forme leurs perceptions est celle d’une croyance largement partagée en un mécanisme de convergence vers la moyenne.

  • Understanding the pathways leading to socioeconomic inequalities in HIV testing uptake in 18 sub-Saharan African countries Article dans une revue:

    Objective: To better understand the different pathways linking socioeconomic position and HIV testing uptake in 18 sub-Saharan African countries. Design: We used cross-sectional population-based surveys between 2010 and 2018. Methods: Using a potential outcomes framework and the product method, we decomposed the total effect linking wealth and recent (<12 months) HIV testing into direct effects, and indirect effects, via internal (related to individual’s ability to perceive need for and to seek care) or external (ability to reach, pay for and engage in healthcare) mediators to calculate the proportion mediated (PM) by each mediator. Results: High levels of inequalities were observed in nine and 15 countries among women and men, respectively. The mediator indirect effect varied greatly across countries. The PM tended to be higher for internal than for external mediators. For instance, among women, HIV-related knowledge was estimated to mediate up to 12.1% of inequalities in Côte d’Ivoire; and up to 31.5% for positive attitudes towards people with HIV (PWH) in Senegal. For the four external mediators, the PM was systematically below 7%. Similar findings were found when repeating analyses on men for the internal mediators, with higher PM by attitudes towards PWH (up to 39.9% in Senegal). Conclusions: Our findings suggest that wealth-related inequalities in HIV testing may be mediated by internal more than external characteristics, with important variability across countries. Overall, the important heterogeneities in the pathways of wealth-related inequalities in HIV testing illustrate that addressing inequalities requires tailored efforts and upstream interventions.

  • Psychological well-being and the tendency to follow official recommendations against COVID-19: A U-shaped relationship? Pré-publication, Document de travail:

    Using nationally representative panel data on 7,766 individuals (22,878 observations), we investigate the association between several well-being indicators (depression, anxiety, stress, and loneliness) and the general tendency to follow official recommendations regarding selfprotection against COVID-19, in France, Germany, Italy, Spain, and Sweden over the course of four data collection waves. Employing a flexible specification that allows the correlation to be non-monotonic, we find a U-shaped relationship, in which transitions to low and high levels of psychological well-being are associated with higher overall compliance, while transitions to medium levels of psychological well-being are associated with less compliance. Moreover, anxiety, stress, and loneliness levels at baseline also have a U-shaped effect on following the recommendations later (i.e., recommendations are followed best by those with lowest and highest levels of anxiety, stress, and loneliness at baseline, while following the recommendations is lowest for those with moderate levels of these variables). These U shapes are in contrast to previous studies which report monotonic relationships between various measures of mental health and compliance, or ambiguous results. Additionally, we observe a U-shaped correlation between the well-being indicators and a number of specific behaviours (including washing hands and mask wearing). Importantly, most of these specific behaviours play a role in the general tendency to follow recommendations. Finally, we uncover the role of gender composition effects in some of our results. While variations in depression and stress are negatively correlated with variations in overall compliance for males, the association is positive for females. The relation in the full sample (composed of males and females) will reflect first the negative slope for males and then the positive slope for females, explaining the U shape

  • Time-Use and Subjective Well-Being: Is there a Preference for Activity Diversity? Pré-publication, Document de travail:

    Using the American and the French time-use surveys, we examine whether people have a preference for a more diversified mix of activities, in the sense that, everything else equal, they experience a higher level of well-being when their agenda is multi-activity, rather than concentrated on a very small number of activities. This could be due to decreasing marginal utility, as is assumed for the consumption of goods, if each episode of time is conceived as yielding a certain level of utility per se. However, in the presence of returns to specialization, people would face a trade-off between the efficiency of specialization and the taste for diversity, as concerns time arrangements. We test these hypotheses and investigate potential gender differences with regard to these patterns.

  • Informative social interactions Article dans une revue:

    Household finances are confidential and discussions are limited to a subset of peers. We collect novel representative survey data to examine separately whether interactions with inner and outer social circles influence return perceptions, expectations, and exposure to a widely known financial instrument in a developed economy with multiple information sources. We find that a respondent’s connectedness, proxied by perceived prevalence of information or participation in the small financial circle, improves expectation accuracy indirectly, through boosting accuracy of perceived past returns; and influences stock participation and exposure not only by influencing expectations, but also directly.

  • Feeling Good Is Feeling Better Article dans une revue:

    Can people remember their past happiness? We analyzed data from four longitudinal surveys from the United States, France, the United Kingdom, and Germany spanning from the 1970s until the present, in which more than 60,000 adults were asked questions about their current and past life satisfaction. We uncovered systematic biases in recalled happiness: On average, people tended to overstate the improvement in their well-being over time and to understate their past happiness. But this aggregate figure hides a deep asymmetry: Whereas happy people recall the evolution of their life to be better than it was, unhappy ones tend to exaggerate their life’s negative evolution. It thus seems that feeling happy today implies feeling better than yesterday. This recall structure has implications for motivated memory and learning and could explain why happy people are more optimistic, perceive risks to be lower, and are more open to new experiences.

    We carry out a difference-indifferences analysis of a representative real-time survey conducted as part of the German SocioEconomic Panel (SOEP) study and show that teleworking had a negative average effect on life satisfaction over the first two years of the COVID-19 pandemic. This average effect hides considerable heterogeneity reflecting genderrole asymmetry: lower life satisfaction is only found for unmarried men and women with school-age children. The negative effect for women with school-age children disappears in 2021, suggesting adaptation to new constraints and/or the adoption of coping strategies.

  • Combined incentive actions, focusing on primary care professionals, to improve cervical cancer screening in women living in socioeconomically disadvantaged geographical areas: a study protocol of a hybrid cluster randomised effectiveness and implementation trial- RESISTE Article dans une revue:

    To cite: Hassine A, Antoni G, Fender M, et al. Combined incentive actions, focusing on primary care professionals, to improve cervical cancer screening in women living in socioeconomically disadvantaged geographical areas: a study protocol of a hybrid cluster randomised effectiveness and implementation trial-RESISTE. BMJ Open 2022;12:e065952. Introduction Cervical cancer (CC) causes thousands of deaths each year. Nearly 100% of cases are caused by oncogenic strains of human papillomavirus (HPV). In most industrialised countries, CC screening (CCS) is based on the detection of HPV infections. For many reasons including lower adherence to CCS, underserved women are more likely to develop CC, and die from it. We aim to demonstrate that the use of incentives could improve screening rates among this population. Methods and analysis Our cluster randomised, controlled trial will include 10 000 women aged 30–65 years eligible for CCS, living in deprived areas in four French departments, two mainlands and two overseas, and who did not perform physician-based HPV testing within the framework of the nationally organised screening programme. HPV self-sampling kit (HPVss) will be mailed to them. Two interventions are combined in a factorial analysis design ending in four arms: the possibility to receive or not a financial incentive of €20 and to send back the self-sampling by mail or to give it to a health professional, family doctor, gynaecologist, midwife or pharmacist. The main outcome is the proportion of women returning the HPVss, or doing a physician-based HPV or pap-smear test the year after receiving the HPVss. 12-month follow-up data will be collected through the French National Health Insurance database. We expect to increase the return rate of HPV self-samples by at least 10% (from 20% to 30%) compared with the postal return without economic incentive. Ethics and dissemination Ethics approval was first obtained on 2 April 2020, then on July 29 2022. The ethics committee classified the study as interventional with low risk, thus no formal consent is required for inclusion. The use of health insurance data was approved by the Commission Nationale Informatique et Libertés on 14 September 2021 (ref No 920276). An independent data security and monitoring committee was established. The main trial results will be submitted for publication in a peer-reviewed journal. Trial registration number NCT04312178 .

  • Multicentre, randomised, economic evaluation of a web-based interactive education platform, simple or enhanced, for patients with end-stage renal disease: the PIC-R trial protocol Article dans une revue:

    Introduction End-stage renal disease (ESRD) affects 84 000 persons in France and costs an estimated €4.2 billion. Education about their disease empowers patients and allows improved management of their disease and better health outcomes. This study aims to explore whether the addition of an interactive web-based platform to patient education is effective and cost-effective and additionally whether complementing the platform with social functions and features improves its performance. Methods and analysis Patients with severe, ESRD or post-transplant will be randomised 1:1:1 to either standard therapeutic education; or education using a specific application; or the enhanced interactive app with social features. The total follow-up duration is 18 months. Primary endpoint is the cost utility of using app-based therapeutic intervention; secondary endpoints are: compliance with treatment guidelines, app use (professionals and patients), patients’ satisfaction, budget impact analysis. Ethics and dissemination The findings will inform the deployment and reimbursement of the application. The study has ethical approval by the Ile de France ethics committee. Dissemination of the results will be presented at conferences and in peer-reviewed publications.

  • Motivational signals disrupt metacognitive signals in the human ventromedial prefrontal cortex Article dans une revue:

    A growing body of evidence suggests that, during decision-making, BOLD signal in the ventromedial prefrontal cortex (VMPFC) correlates both with motivational variables – such as incentives and expected values – and metacognitive variables – such as confidence judgments – which reflect the subjective probability of being correct. At the behavioral level, we recently demonstrated that the value of monetary stakes bias confidence judgments, with gain (respectively loss) prospects increasing (respectively decreasing) confidence judgments, even for similar levels of difficulty and performance. If and how this value-confidence interaction is reflected in the VMPFC remains unknown. Here, we used an incentivized perceptual decision-making fMRI task that dissociates key decision-making variables, thereby allowing to test several hypotheses about the role of the VMPFC in the value-confidence interaction. While our initial analyses seemingly indicate that the VMPFC combines incentives and confidence to form an expected value signal, we falsified this conclusion with a meticulous dissection of qualitative activation patterns. Rather, our results show that strong VMPFC confidence signals observed in trials with gain prospects are disrupted in trials with no – or negative (loss) – monetary prospects. Deciphering how decision variables are represented and interact at finer scales seems necessary to better understand biased (meta)cognition.

  • Two Person Bargaining Mechanisms: A Laboratory Experiment. Article dans une revue:

    We conduct a series of experiments in which two subjects bargain over five options. Following an experimental design closely related to De Clippel et al. (Am Econ Rev 104:3434-3458, 2014), we evaluate the performance of three bargaining mechanisms: (alpha) one subject shortlists a block of three options before the other chooses one among them, (ss) both subjects veto options simultaneously and in a block, and (gamma) both subjects veto options simultaneously and gradually one after the other. We document that the non-symmetric shortlisting mechanism (alpha) is highly efficient, but our data also suggest the existence of a first-mover advantage as subjects become more experienced. The simultaneous mechanism (ss) is less efficient than (alpha) and generates a high level of ex-post inequality. The gradual veto mechanism (gamma) is no less efficient than (alpha), but has the important advantage of shutting down the possibility of any first-mover advantage.

  • The impact of COVID-19 lockdown stringency on loneliness in five European countries Article dans une revue:

    Rationale The coronavirus pandemic has forced governments to implement a variety of different dynamic lockdown-stringency strategies in the last two years. Extensive lockdown periods could have potential unintended consequences on mental health, at least for at-risk groups. Objective We present novel evidence on the heterogeneous direct and indirect effects of lockdown-stringency measures on individuals’ perception of social isolation (i.e. loneliness) using panel data from five European countries (Germany, France, Spain, Italy and Sweden), which tracks changes in both in-person and remote social interactions between May 2020 and March 2021. Method We combine data from the COME-HERE panel survey (University of Luxembourg) and the Oxford COVID-19 Government Response Tracker (OxCGRT). We implement a dynamic mixture model in order to estimate the loneliness sub-population classes based on the severity of loneliness, as well as the evolution of social interactions. Results While loneliness is remarkably persistent over time, we find substantial heterogeneity across individuals, identifying four latent groups by loneliness severity. Group membership probability varies with age, gender, education and cohabitation status. Moreover, we note significant differences in the impact of social interactions on loneliness by degree of severity. Older people are less likely to feel lonely, but were more affected by lockdown measures, partly due to a reduction in face-to-face interactions. On the contrary, the younger, especially those living alone, report high levels of loneliness that are largely unaffected by changes in the pandemic after lockdown measures were initially implemented. Conclusions Understanding the heterogeneity in loneliness is key for the identification of at-risk populations that can be severely affected by extended lockdown measures. As part of public-health crisis-response systems, it is critical to develop support measures for older individuals living alone, as well as promoting continuous remote communication for individuals more likely to experience high levels of loneliness.

  • Occupational status and life satisfaction in the UK: The miserable middle? Article dans une revue:

    We use British panel data to explore the link between occupational status and life satisfaction. We find puzzling evidence for men of a U-shaped relationship in cross-section data: employees in medium-status occupations report lower life satisfaction scores than those of employees in either low- or high-status occupations. This puzzle disappears in panel data: the satisfaction of any man rises as he moves up the status ladder. The culprit seems to be immobility: the miserable middle is caused by men who have always been in medium-status occupations. There is overall little evidence of a link between occupational status and life satisfaction for women, although this relationship for higher-educated women does look more like that for men.

  • Characteristics associated with COVID-19 vaccine hesitancy Article dans une revue:

    Understanding what lies behind actual COVID-19 vaccine hesitancy is fundamental to help policy makers increase vaccination rates and reach herd immunity. We use June 2021 data from the COME-HERE survey to explore the predictors of actual vaccine hesitancy in France, Germany, Italy, Luxembourg, Spain and Sweden. We estimate a linear-probability model with a rich set of covariates and address issues of common-method variance. 13% of our sample say they do not plan to be vaccinated. Post-Secondary education, home-ownership, having an underlying health condition, and one standard-deviation higher age or income are all associated with lower vaccine hesitancy of 2–4.5% points. Conservative-leaning political attitudes and a one standard-deviation lower degree of confidence in the government increase this probability by 3 and 6% points respectively. Vaccine hesitancy in Spain and Sweden is significantly lower than in the other countries.

  • Gender, loneliness and happiness during COVID-19 Article dans une revue:

    We analyse a measure of loneliness from a representative sample of German individuals interviewed in both 2017 and at the beginning of the COVID-19 pandemic in 2020. Both men and women felt lonelier during the COVID-19 pandemic than they did in 2017. The pandemic more than doubled the gender loneliness gap: women were lonelier than men in 2017, and the 2017-2020 rise in loneliness was far larger for women. This rise is mirrored in life-satisfaction scores. Men’s life satisfaction changed only little between 2017 and 2020; yet that of women fell dramatically, and sufficiently so to produce a female penalty in life satisfaction. We estimate that almost all of this female penalty is explained by the disproportionate rise in loneliness for women during the COVID-19 pandemic.

By comparing the answers of the randomly drawn citizens with those of the general population on identical questions, we assess the representativity of the CCC, study the evolution of the citizens’ opinions, and document the perceptions of the CCC. The CCC appeared broadly representative of the French population. Although, the CCC’s Citizens seemed to have been somewhat more favorable to climate policies than the general population at the start, a majority support was found for all proposed measures but one. Despite our findings that the CCC correctly represented the population, we document widespread ignorance and mistrust towards the CCC, including a largely shared belief that it was not representative.

    This paper provides one of the first testsof adaptation tothe complete set ofresidential transitions. We use long-run SOEP panel data and consider the impact of all housing transitions, whether or not they involvea change in housing tenureor geographical movement, on both life satisfaction and housing satisfaction. Controlling for individual characteristics and housing quality, some residential transitionsaffect life satisfactiononly little, while all transitions have a significant effect on housing satisfaction. This latter is particularly large for renters who become homeowners and move geographically,and for renters who move without changing tenure status. Regarding housing satisfaction, we find very little evidence of adaptation even after five years. Losing homeowner status is the only transition that produces lower housing satisfaction, and here the effect seems to become even more negative over time.

  • The social cost of carbon and inequality: When local redistribution shapes global carbon prices Article dans une revue:

    The social cost of carbon is a central metric for optimal carbon prices. Previous literature shows that inequality significantly influences the social cost of carbon, but mostly omits het-erogeneity below the national level. We present an optimal taxation model of the social cost of carbon that accounts for inequality between and within countries. We find that climate and distributional policy can generally not be separated. If only one country does not compen-sate low-income households for disproportionate damages, the social cost of carbon tends to increase globally. Optimal carbon prices remain roughly unchanged if national redistribu-tion leaves inequality between households unaffected by climate change and if the utility of households is approximately logarithmic in consumption.

  • Fair Utilitarianism Article dans une revue:

    Utilitarianism plays a central role in economics, but there is a gap between theory, where it is dominant, and applications, where monetary criteria are often used. For applications, a key di culty for utilitarianism remains to de ne how utilities should be measured and compared across individuals. Drawing on Harsanyi’s approach (Harsanyi, 1955) involving choices in risky situations, we introduce a new normalization of utilities that is the only one ensuring that: 1) a transfer from a rich to a poor is welfare enhancing, and 2) populations with more risk averse people have lower welfare. We embed these requirements in a new characterization of utilitarianism and study some implications of this “fair utilitarianism” for risk sharing, collective risk aversion and the design of health policy.

  • Happier Elderly Residents. The positive impact of physical activity on objective and subjective health condition of elderly people in nursing homes. Evidence from a multi-site randomized controlled trial Article dans une revue:

    We explore the effects of adapted physical exercise programs in nursing homes, in which some residents suffer from dementia and/or physical limitations and other do not. We use data from 452 participants followed over 12 months in 32 retirement homes in four European countries. Using a difference-in-difference with individual random effects model, we show that the program has exerted a significant impact on the number of falls and the self-declared health and health-related quality of life of residents (EQ-5D). The wide scope of this study, in terms of sites, countries, and measured outcomes, brings generality to previously existing evidence. A simple computation, in the case of France, suggests that such programs are highly cost-efficient.

  • The Fall in Income Inequality during COVID-19 in Four European Countries Pré-publication, Document de travail:

    We here use panel data from the COME-HERE survey to track income inequality during COVID-19 in France, Germany, Italy, and Spain. Relative inequality in equivalent household disposable income among individuals changed in a hump-shaped way between January 2020 and January 2021, with an initial rise from January to May 2020 being more than reversed by September 2020. Absolute inequality also fell over this period. Due to the pandemic some households lost more than others, and government compensation schemes were targeted towards the poorest, implying that on average income differences decreased. Generalized Lorenz domination reveals that these distributive changes reduced welfare in Italy.

  • Climate change and population: an assessment of mortality due to health impacts Article dans une revue:

    We develop a model of population dynamics accounting for the impact of climate change on mortality through ve channels (heat, diarrhoeal disease, malaria, dengue, undernutrition). An age-dependent mortality, which depends on global temperature increase, is introduced and calibrated. We consider three climate scenarios (RCP 6.0, RCP 4.5 and RCP 2.6) and find that the five risks induce deaths in the range from 135,000 per annum (in the near term) to 280,000 per annum (at the end of the century) in the RCP 6.0 scenario. We examine the number of life-years lost due to the five selected risks and find figures ranging from 4 to 9 million annually. These numbers are too low to impact the aggregate dynamics but they have interesting evolution patterns. The number of life-years lost is constant (RCP 6.0) or decreases over time (RCP 4.5 and RCP 2.6). For the RCP 4.5 and RCP 2.6 scenarios, we find that the number of life-years lost is higher today than in 2100, due to improvements in generic mortality conditions, the bias of those improvements towards the young, and an ageing population. From that perspective, the present generation is found to bear the brunt of the considered climate change impacts.

We show that any equilibrium of the κ-universalization of this extended game is an equilibrium of the base game played by altruistic players (« ex ante Homo Moralis is altruistic »), and that the converse is false. The paper presents the implications of this remark for the philosophical nature of ethical behavior (Kantianism behind the veil of ignorance implies but is stronger than altruism) and for its evolutionary foundations.

  • Prenatal Economic Shocks and Birth Outcomes Article dans une revue:

    We consider the effects of major prenatal economic shocks experienced by mothers on two indicatorsof newborn-infant health, birth weight and head circumference, using detailed microdata from the UKALSPAC survey. Controlling for physiological and socioeconomic factors, an economic shock in the first18 weeks of gestation lowers birth weight by 40-70 grams and head circumference by 2-3mm. We findevidence of transmission via poorer maternal health due to absolute material deprivation and tobaccoand alcohol consumption, but not for the endocrinological effects of increased psychosocial anxiety. Thefragile-male hypothesis holds for birth weight but not for head circumference, as predicted by recenttheories on gender differences in prenatal development.

  • The Fall in Income Inequality during COVID-19 in Five European Countries Pré-publication, Document de travail:

    We here use panel data from the COME-HERE survey to track income inequality during COVID-19 in France, Germany, Italy, Spain and Sweden. Relative inequality in equivalent household disposable income among individuals changed in a hump-shaped way over 2020. An initial rise from January to May was more than reversed by September. Absolute inequality also fell over this period. As such, policy responses may have been of more benefit for the poorer than for the richer.

  • The Planetary Wellbeing Initiative: Pursuing the Sustainable Development Goals in Higher Education Article dans une revue:

    We live in a time of pressing planetary challenges, many of which threaten catastrophic change to the natural environment and require massive and novel coordinated scientific and societal efforts on an unprecedented scale. Universities and other academic institutions have the opportunity and responsibility to assume a leading role in an era when the destiny of the planet is precisely in the hands of human beings. Drawing on the Planetary Health project promoted by the Rockefeller Foundation and The Lancet, Pompeu Fabra University launched in 2018 the Planetary Wellbeing Initiative, a long-term institutional strategy also animated by the United Nations Sustainable Development Goals (SDGs). Planetary Wellbeing might be defined as the highest attainable standard of wellbeing for human and non-human beings and their social and natural systems. Developing the potential of these new concepts involves a substantial theoretical and empirical effort in many different fields, all of them interrelated by the crosscutting challenges of global complexity, interdisciplinarity, and urgency. Close collaboration of science, humanities, and culture is more desperately needed now than ever before in the history of humankind.

    The Repugnant Conclusion is an implication of some approaches to population ethics. It states, in Derek Parfit’s original formulation, For any possible population of at least ten billion people, all with a very high quality of life, there must be some much larger imaginable population whose existence, if other things are equal, would be better, even though its members have lives that are barely worth living.

  • Hospital payment schemes and high-priced drugs: Evidence from the French Add-on List Article dans une revue:

    Under prospective payment schemes, hospitals may be disincentivised to use high-priced drugs. In this context, supplementary payment schemes have been implemented to fund hospitals beyond hospital tariffs for the use of such technologies. In France, since 2004, an add-on list scheme ensures that listed high-priced drugs are reimbursed by the state, thereby imposing no cost on hospitals while drugs are on the list. Yet little is known about the impact of drug delisting, i.e., when drugs are removed from the add-on list, on hospital utilisation. In this paper, we investigate the effects of delisting for 12 cancer drugs on the volumes prescribed, the generic shares and the purchase prices negotiated by hospitals. Using French hospital-level data over the period 2008-2016, we construct volumes, generic shares and purchase prices at the molecule level to account for potential substitutions across therapeutically equivalent drugs. Hospital fixed effects allow for time-invariant unobserved hospital heterogeneity linked to e.g., prescription preferences or hospitals’ bargaining power. Our results indicate that prescription volumes, generic shares and price levels are not systematically affected by delisting, nor do we find evidence of response heterogeneity by hospital type. Overall, our findings mitigate concerns that the financial incentives associated with add-on lists may lead to hospitals over-prescribing high-priced drugs.

  • Do truth-telling oaths improve honesty in crowd-working? Article dans une revue:

    This study explores whether an oath to honesty can reduce both shirking and lying among crowd-sourced internet workers. Using a classic coin-flip experiment, we first confirm that a substantial majority of Mechanical Turk workers both shirk and lie when reporting the number of heads flipped. We then demonstrate that lying can be reduced by first asking each worker to swear voluntarily on his or her honor to tell the truth in subsequent economic decisions. Even in this online, purely anonymous environment, the oath significantly reduced the percent of subjects telling “big” lies (by roughly 27%), but did not affect shirking. We also explore whether a truth-telling oath can be used as a screening device if implemented after decisions have been made. Conditional on flipping response, MTurk shirkers and workers who lied were significantly less likely to agree to an ex-post honesty oath. Our results suggest oaths may help elicit more truthful behavior, even in online crowd-sourced environments

  • Designing Preference Voting Article dans une revue:

    Electoral systems in which voters can cast preference votes for individual candidates within a party list are increasingly popular. To the best of our knowledge, there is no research on whether and how the scale used to evaluate candidates can affect electoral behavior and results. In this paper, we analyze data from an original voting experiment leveraging real-life political preferences and embedded in a nationally representative online survey in Austria. We show that the scale used by voters to evaluate candidates makes differences. For example, the possibility to give up to two points advantages male candidates because male voters are more likely to give ‘zero points’ to female candidates. Yet this pattern does not exist in the system in which voters can give positive and negative points because male voters seem reluctant to actively withdraw points from female candidates. We thus encourage constitution makers to think carefully about the design of preference voting.

  • The Age U-shape in Europe: The Protective Role of Partnership Article dans une revue:

    In this study, we ask whether the U-shaped relationship between life satisfactionand age is flatter for individuals who are partnered. An analysis of cross-sectionalEU-SILC data indicates that the decline in life satisfaction from the teens to thefifties is almost four times larger for non-partnered than for partnered individuals,whose life satisfaction essentially follows a slight downward trajectory with age.However, the same analysis applied to three panel datasets (BHPS, SOEP andHILDA) reveals a U-shape for both groups, albeit somewhat flatter for the partneredthan for the non-partnered individuals. We suggest that the difference between thecross-sectional and the panel results reflects compositional effects: i.e., there isa significant shift of the relatively dissatisfied out of marriage in mid-life. Thesecompositional effects tend to flatten the U-shape in age for the partnered individualsin the cross-sectional data.

  • Children, Unhappiness and Family Finances Article dans une revue:

    The common finding of a zero or negative correlation between the presence of children and parental well-being continues to generate research interest. We consider international data, including well over one million observations on Europeans from 11 years of Eurobarometer surveys. We first replicate this negative finding, both in the overall data and then for most different marital statuses. Children are expensive: controlling for financial difficulties turns our estimated child coefficients positive. We argue that difficulties paying the bills explain the pattern of existing results by parental education and income and by country income and social support. Last, we underline that not all children are the same, with stepchildren commonly having a more negative correlation with well-being than children from the current relationship.

  • Climate action with revenue recycling has benefits for poverty, inequality and well-being Article dans une revue:

    Existing estimates of optimal climate policy ignore the possibility that carbon tax revenues could be used in a progressive way; model results therefore typically imply that near-term climate action comes at some cost to the poor. Using the Nested Inequalities Climate Economy (NICE) model, we show that an equal per capita refund of carbon tax revenues implies that achieving a 2 °C target can pay large and immediate dividends for improving well-being, reducing inequality and alleviating poverty. In an optimal policy calculation that weighs the benefits against the costs of mitigation, the recommended policy is characterized by aggressive near-term climate action followed by a slower climb towards full decarbonization; this pattern—which is driven by a carbon revenue Laffer curve—prevents runaway warming while also preserving tax revenues for redistribution. Accounting for these dynamics corrects a long-standing bias against strong immediate climate action in the optimal policy literature

  • Social externalities and economic analysis Article dans une revue:

    This paper considers and assesses the concept of social externalities through human interdependence, in relation to the economic analysis of externalities in the tradition of Pigou and Arrow, including the analysis of the commons. It argues that there are limits to economic analysis. Our proposal is to enlarge the perspective and start thinking about a broader framework in which can be attached the « externality » label and be scrutinized for the likely negative consequences that result from the divergence. A tentative and probably incomplete list of possible internalizing mechanisms includes: pricing and monetary incentives; altruism and solidarity; moral norms; reciprocity and mutual monitoring; centralized cooperative decision-making; and merger. There are clear reasons why the pricing mechanism is not appropriate in some cases. A more difficult question to answer is what factors determine which of the mechanisms is the appropriate one to rely on in a given sphere of relations and activities. The object of the paper is to encourage research and contributions from all the relevant disciplines of social sciences about the pervasive human interdependence that the notion of social externalities tries to capture.

  • Demography and Well-being Article dans une revue:

    Demography studies the characteristics of populations. One such characteristic is well-being: this was the subject of the 2019 Wittgenstein Conference. Here, I discuss how objective well-being domains can be summarised to produce an overall well-being score, and how taking self-reported (subjective) well-being into account may help in this effort. But given that there is more than one type of subjective well-being score, we would want to know which one is “best”. We would also need to decide whose well-being counts, or counts more than that of others. Finally, I briefly mention the potential role of adaptation and social comparisons in the calculation of societal well-being.

    L’analyse économique des programmes d’activité physique contribue à faire avancer la question de la prise en charge de ces programmes par la collectivité.L’efficacité de l’activité physique et sportive dans la prévention [66] ou le traitement de maladies chroniques est aujourd’hui établie de manière robuste [31, 53]. Sur la base des études disponibles, un certain nombre de pays a déjà adopté des mesures visant à développer l’activité physique sur un continuum entre la pratique sportive régulière, l’activité physique en prévention et le traitement de certaines pathologies (seule ou en complément d’une autre thérapeutique). Pionnière en la matière, la Suède autorise depuis deux décennies déjà la prescription d’activité physique par le médecin généraliste aux patients à risque ou souffrant d’une pathologie chronique. En France, il aura fallu attendre la loi de santé de janvier 2016 pour que les médecins traitants aient la possibilité de prescrire une activité physique adaptée (APA) aux patients atteints d’une affection de longue durée (ALD). Les réseaux et dispositifs de sport santé se sont dès lors rapidement développés, souvent coordonnés et référencés au niveau local par les agences régionales de santé (ARS)

  • The long-lasting effects of family and childhood on adult wellbeing: Evidence from British cohort data Article dans une revue:

    To what extent do childhood experiences continue to affect adult wellbeing over the life course? Previous work on this link has been carried out either at one particular adult age or for some average over adulthood. We here use two British birth-cohort datasets (the 1958 NCDS and the 1970 BCS) to map out the time profile of the effect of childhood experiences on adult outcomes, including life satisfaction. We find that the effects of many aspects of childhood do not fade away over time but are rather remarkably stable. In both birth-cohorts, child non-cognitive skills are the strongest predictors of adult life satisfaction at all ages. Of these, emotional health is the strongest. Childhood cognitive performance is more important than good conduct in explaining adult life satisfaction in the earlier NCDS cohort, whereas this ranking is inverted in the more recent BCS.

    The COVID-19 pandemic has led many governments to implement lockdowns. While lockdowns may help to contain the spread of the virus, they may result in substantial damage to population well-being. We use Google Trends data to test whether the lockdowns implemented in Europe and America led to changes in well-being related topic search terms. Using differences-in-differences and a regression discontinuity design to evaluate the causal effects of lockdown, we find a substantial increase in the search intensity for boredom in Europe and the US. We also found a significant increase in searches for loneliness, worry and sadness, while searches for stress, suicide and divorce on the contrary fell. Our results suggest that people’s mental health may have been severely affected by the lockdown.

  • Wage Satisfaction and Reference Wages Chapitre d’ouvrage:

    That wage satisfaction depends on reference wage is now an acquis of the empirical happiness literature. Employees care about their coworkers’ wage. They compare to different notions of reference wage and suffer from disadvantageous comparisons, more than they enjoy advantageous ones. However, reference wage sometimes acts in a positive way, as a carrier of information. In terms of methods, the empirical literature has developed in three stages. First, it started by enquiring about the statistical association between a notion of reference wage (or reference income) as defined by researchers, and self-declared satisfaction. Second, some researchers tried to elicit the direction of income comparisons by including direct questions in large surveys of the population. Third, researchers attempted to provide experimental evidence of the causal effect of comparisons on satisfaction (beyond the simple statistical association) using natural, field, and lab experiments.

  • Early-life correlates of later-life well-being: Evidence from the Wisconsin Longitudinal Study Article dans une revue:

    We here use data from the Wisconsin Longitudinal Study (WLS) to provide one of the first analyses of the distal (early-life) and proximal (later-life) correlates of older-life subjective well-being. Unusually, we have two distinct measures of the latter: happiness and eudaimonia. Even after controlling for proximal covariates, outcomes at age 18 (IQ score, parental income and parental education) remain good predictors of well-being over 50 years later. In terms of the proximal covariates, mental health and social participation are the strongest predictors of both measures of well-being in older age. However, there are notable differences in the other correlates of happiness and eudaimonia. As such, well-being policy will depend to an extent on which measure is preferred.

  • Evaluating the Impact of Intensive Case Management for Severe Vocational Injuries on Work Incapacity and Costs Article dans une revue:

    Purpose This study investigates the impact of an intensive case management program on sick leave days, permanent work incapacity levels and treatment costs for severe vocational injuries set up by the French National Insurance Fund in five health insurance districts. Methods The method employed relies on a four-step matching procedure combining Coarsened Exact Matching and Propensity Score Matching, based on an original administrative dataset. Average Treatment effects on the Treated were estimated using a parametric model with a large set of covariates. Results After one-year follow-up, workers in the treatment group had higher sickness absence rates, with 22 extra days, and the program led to 2.7 (95% CI 2.3–3.1) times more diagnoses of permanent work incapacity in the treatment group. With an estimated yearly operational cost of 2,722 € per treated worker, the average total extra treatment cost was 4,569 € for treated workers, which corresponds to a cost increase of 29.2% for the insurance fund. Conclusions The higher costs found for the treatment group are mainly due to longer sick leave duration for the moderate severity group, implying higher cash transfers in the form of one-off indemnities. Even though workers in the treated group have more diagnoses of permanent work incapacity, the difference of severity between groups is small. Our results on longer sick leave duration are partly to be explained by interactions between the case managers and the occupational physicians that encouraged patients to stay longer off-work for better recovery, despite the higher costs that this represented for the insurance fund and the well-documented adverse side effects of longer periods off-work.

  • Fully Bayesian Aggregation Article dans une revue:

    Can a group be an orthodox rational agent? This requires the group’s aggregate preferences to follow expected utility (static rationality) and to evolve by Bayesian updating (dynamic rationality). Group rationality is possible, but the only preference aggregation rules which achieve it (and are minimally Paretian and continuous) are the linear-geometric rules, which combine individual values linearly and combine individual beliefs geometrically. Linear-geometric preference aggregation contrasts with classic linear-linear preference aggregation, which combines both values and beliefs linearly, but achieves only static rationality. Our characterisation of linear-geometric preference aggregation has two corollaries: a characterisation of linear aggregation of values (Harsanyi’s Theorem) and a characterisation of geometric aggregation of beliefs.

    We here address the causal relationship between maternal depression and child human capital using UK cohort data. We exploit the conditionally-exogenous variation in mothers’ genomes in an instrumental-variable approach, and describe the conditions under which mother’s genetic variants can be used as valid instruments. An additional episode of maternal depression between the child’s birth up to age nine reduces both their cognitive and non-cognitive skills by 20 to 45% of a SD throughout adolescence. Our results are robust to a battery of sensitivity tests addressing, among others, concerns about pleiotropy and the maternal transmission of genes to her child.

  • The Relation between Degrees of Belief and Binary Beliefs: A General Impossibility Theorem Chapitre d’ouvrage:

    Agents are often assumed to have degrees of belief (“credences”) and also binary beliefs (“beliefs simpliciter”). How are these related to each other? A much-discussed answer asserts that it is rational to believe a proposition if and only if one has a high enough degree of belief in it. But this answer runs into the “lottery paradox”: the set of believed propositions may violate the key rationality conditions of consistency and deductive closure. In earlier work, we showed that this problem generalizes: there exists no local function from degrees of belief to binary beliefs that satisfies some minimal conditions of rationality and non-triviality. “Locality” means that the binary belief in each proposition depends only on the degree of belief in that proposition, not on the degrees of belief in others. One might think that the impossibility can be avoided by dropping the assumption that binary beliefs are a function of degrees of belief. We prove that, even if we drop the “functionality” restriction, there still exists no local relation between degrees of belief and binary beliefs that satisfies some minimal conditions. Thus functionality is not the source of the impossibility; its source is the condition of locality. If there is any non-trivial relation between degrees of belief and binary beliefs at all, it must be a “holistic” one. We explore several concrete forms this “holistic” relation could take.

    We here consider the cognitive and noncognitive consequences on young adults of growing up with a mother who reported experiencing major financial problems. We use UK data from the Avon Longitudinal Study of Parents and Children to show that early childhood financial problems are associated with worse adolescent cognitive and noncognitive outcomes, controlling for both income and a set of standard variables, and in value‐added models controlling for children’s earlier age‐5 outcomes. The estimated effect of financial problems is almost always larger in size than that of income. Around one‐quarter to one‐half of the effect of financial problems on the noncognitive outcomes seems to transit through mother’s mental health.

  • Le Bien-être en France Ouvrages:

    Depuis sa création, il y a quatre ans, l’Observatoire du bien-être se donne la mission de scruter le bien-être des Français ; le présent rapport vise à donner une image de cette activité, et ce faisant, à dresser un portrait de la France au prisme du bien-être subjectif.Le travail, d’abord, qui joue un rôle primordial dans la satisfaction, non seulement à cause du revenu qu’il procure, mais aussi par les relations sociales qu’il occasionne et du sens qu’il donne à l’activité individuelle. C’est d’ailleurs surtout à travers la sphère professionnelle que le niveau d’éducation contribue à la satisfaction. On constate hélas que dans le domaine du travail, peut-être plus que dans tout autre, le célèbre « déficit de bonheur français » s’exprime à travers un niveau d’insatisfaction plus élevé que chez nos voisins européens. C’est peut-être pourquoi, à l’inverse de nombreux pays, le passage à la retraite ne semble pas constituer en France une charnière difficile, de nature à provoquer une baisse de bien-être, même s’il occasionne une perte de revenu. Pour les chômeurs, il représente même une sortie de la précarité et du stigmate, nettement favorable au bien-être.Les liens sociaux et privés ensuite, dont on mesure l’importance, en creux, par le sentiment de solitude particulièrement délétère qui s’exprime dans certaines communes du territoire français. C’est en effet dans les territoires en déclin démographique, d’où la vie sociale se retire, que l’on a vu récemment se manifester des signes de fort mécontentement : insatisfaction, abstention électorale, et manifestations de Gilets jaunes.Au total, les Français se classent plus mal que les autres Européens sur un grand nombre de mesures subjectives de bien-être malgré une situation beaucoup moins défavorable en matière d’indicateurs objectifs. Nous y voyons le signe d’une société inquiète, mal à l’aise avec les transformations qui la traversent. Peut-être aussi, dans une société centralisée où l’on attend beaucoup de l’Etat, est-il particulièrement angoissant de voir l’échelle nationale largement dépassée par l’ampleur des changements mondiaux. Le dernier chapitre de cet ouvrage ajoute une profondeur historique à l’analyse, et suggère que la notion de crise, apparue au milieu des années 1970, s’est durablement installée dans la société française, ainsi que le pessimisme et l’insatisfaction qui l’accompagnent.Ces observations, réalisées au cours des années passées, revêtent une teneur nouvelle à la lumière de la crise du Covid-19. Si le gouvernement fait face à un arbitrage cornélien entre la lutte contre l’épidémie et l’économie, il prend aussi progressivement conscience de la nécessité de préserver le bien-être et la santé mentale de la population.

    We use annual data on over 150 countries between 2005 and 2018 to look at the relationship between subjective well-being (both cognitive and affective) and the Human Development Index (HDI). The HDI appears to be more closely related to cognitive than affective well-being. We also consider the relationships between the three HDI components (the Income, Health and Education Indices) and well-being, and find that, on average, the Income Index has the strongest predictive power. Importantly, we find that the three HDI components only matter equally in Western and rich countries. Our analysis contributes to the discussion about cultural sensitivity in paradigms of societal development in two ways. We first show that differences in preferences towards development aims exist. Second, we propose a weighting procedure for a culturally-sensitive version of the HDI.

  • Job quality and workplace gender diversity in Europe Article dans une revue:

    We here consider the relationship between workplace gender measures and employees’ perceived job quality, where the former cover both the gender mix of workers with the same job title and the gender of the immediate boss. Data from the 2015 European Working Conditions Survey show that men’s job evaluation is higher in gender-balanced job positions at the workplace, while that of women is higher in either gender-balanced or male-dominated positions. The gender of the immediate boss plays no significant role in employee job evaluation. There is some evidence that these correlations differ by job-quality domains. We introduce co-worker support and help, gender discrimination, and unwanted sexual attention as possible mediators of the gender-mix correlations: these change the estimated coefficients only little. Our estimated correlations could therefore reflect a pure preference for job-position gender composition. Last, we use a bounding approach to show that our main results are robust to the potential influence of unobservables. Overall, job-position gender diversity is associated with higher worker well-being.

Policy responses are measured by the Stringency Index and the Economic Support Index from the Blavatnik School of Government. Stringency is systematically associated with lower life satisfaction, controlling for the intensity of the pandemic itself. This stringency effect is larger for women, those with weak ties to the labour market, and in richer households. The effect of the Economic Support is never statistically different from zero.

  • When redistribution makes personalized pricing of externalities useless Article dans une revue:

    We consider a standard optimal taxation framework in which consumers’ preferences are separable in consumption and labor and identical over consumption, but are affected by consumption externalities. For every nonlinear, income-dependent pricing of goods there is a linear pricing scheme, combined with an adjusted income tax schedule, that leaves all consumers equally well-off and weakly increases the government’s budget. The result depends on whether a linear pricing scheme exists that keeps the aggregate amount of consumption at its initial level observed under nonlinear pricing. We provide sufficient conditions for the assumption to hold. If adjusting the income tax rate is not available, personalized prices for an externality can enhance social welfare if they are redistributive, that is, favor consumers with a larger marginal social value of income.

    Savage famously contravened his own theory when first confronting the Allais Paradox, but then convinced himself that he had made an error. We examine the formal structure of Savage’s ‘error-correcting’ reasoning in the light of (i) behavioural economists’ claims to identify the latent preferences of individuals who violate conventional rationality requirements and (ii) Broome’s critique of arguments which presuppose that rationality requirements can be achieved through reasoning. We argue that Savage’s reasoning is not vulnerable to Broome’s critique, but does not provide support for the view that behavioural scientists can identify and counteract errors in people’s choices or preferences.

La contribution de ces travaux à l’élaboration des politiques publiques tient à leur capacité à analyser et comprendre la manière dont les acteurs économiques réagissent aux évolutions de l’environnement dans lequel ils prennent leurs décisions. Ce raisonnement repose sur des hypothèses de comportement fortes, faisant l’objet d’un nouveau courant de recherche, l’économie comportementale, qui allie psychologie et économie afin d’affiner la compréhension des déterminants des décisions. Ce livre dresse un panorama des apports de ce nouveau courant à la définition et à l’évaluation des politiques publiques. Il décrit les nouveaux outils d’intervention, comme les nudges, tout en soulignant la pertinence des outils d’intervention traditionnels. Il en propose une application en matière d’économie de la santé, de choix d’épargne et de retraite, de politique environnementale et de régulation du marché du travail.

  • Toward a theory of ecosystem well-being Article dans une revue:

    Can the main methods of social welfare analysis be extended to cover multiple species? Following a non-anthropocentric approach, we examine the pros and cons of various objective and subjective methods of well-being comparisons across species. We argue against normalizing by specific capacities but in favor of taking account of individual preferences and specializations. While many conceptual and practical difficulties remain, it appears possible to develop methods for the assessment of collective well-being of multi-species communities and ecosystems.

  • A solution to the two-person implementation problem Article dans une revue:

    We propose strike mechanisms as a solution to the classical problem of Hurwicz and Schmeidler (1978) and Maskin (1999) according to which, in two-person societies, no Pareto efficient rule is Nash-implementable. A strike mechanism specifies the number of alternatives that each player vetoes. Each player simultaneously casts these vetoes and the mechanism selects randomly one alternative among the non-vetoed ones. For strict preferences over alternatives and under a very weak condition for extending preferences over lotteries, these mechanisms are deterministic-in-equilibrium. They Nash implement a class of Pareto efficient social choice rules called Pareto-and-veto rules. Moreover, under mild richness conditions on the domain of preferences over lotteries, any Pareto efficient Nash-implementable rule is a Pareto-and-veto rule and hence is implementable through a strike mechanism.

  • Living in the Shadow of the Past: Financial Profiles and Well‐Being Article dans une revue:

    We here consider the link between individual financial profiles over time and well‐being, as measured by life satisfaction. We in particular look at annual self‐reported financial worsening and improvement information for over 25,000 individuals in Australian panel data from 2002 to 2017. We first find that satisfaction falls (rises) with a contemporaneous major financial worsening (improvement), with the largest correlation being with financial worsening. Second, the experience of these financial events in the past continues to be linked to current well‐being. Last, only the order of financial‐improvement spells relates to well‐being: a given number of past years where finances deteriorated has the same association with current well‐being whether the deterioration occurred in one continuous spell or was interrupted. We last show that these associations are heterogeneous over the distribution of well‐being.

  • Preparing for the tax reform: the risky French households’ portfolio in 2018 Pré-publication, Document de travail:

    Entre 2004 et 2014, le nombre d’actionnaires en France a diminué d’environ 50%. Cette frilosité des épargnants observée après la crise de 2008 semble cependant aujourd’hui moins d’actualité, d’autant plus que l’année 2017 a été marquée par une réforme fiscale visant à soutenir l’actionnariat:mise en place d’une flat tax et suppression de l’ISF, remplacé par l’impôt sur la fortune immobilière. Nous analysons ici les portefeuilles risqués des ménages français à partir des deux dernières vagues (2014-2015 et 2017-2018) de l’enquête «Histoire de vie et patrimoine» de l’INSEE, qui présentent aujourd’hui l’avantage d’être pénalisées. Bien que l’enquête 2017-2018 arrive un peu tôt pour étudier l’impact de ces réformes, cet article propose une analyse originale de la dynamique des portefeuilles risqués des ménages sur les trois dernières années,juste avant (et peu après) la mise en œuvre de ces politiques. Nous montrons tout d’abord que la demande d’actifs risqués dépend fortement du niveau de richesse des ménages et des anticipations de rendement sur le marché boursier, deux variables qui ont vraisemblablement été affectées par les récentes réformes fiscales. Ces données permettent également d’évaluer si l’annonce de ces réformes a eu une incidence sur la demande d’actions.

  • Compensating for academic loss: Online learning and student performance during the COVID-19 pandemic Article dans une revue:

    The COVID-19 pandemic has led to widespread school shutdowns, with many continuing distance education via online-learning platforms. We here estimate the causal effects of online education on student exam performance using administrative data from Chinese Middle Schools. Taking a difference-in-differences approach, we find that receiving online education during the COVID-19 lockdown improved student academic results by 0.22 of a standard deviation, relative to pupils without learning support from their school. Not all online education was equal: students who were given recorded online lessons from external higher-quality teachers had higher exam scores than those whose lessons were recorded by teachers from their own school. The educational benefits of distance learning were the same for rural and urban students, but the exam performance of students who used a computer for online education was better than those who used a smartphone. Last, while everyone except the very-best students performed better with online learning, it was low achievers who benefited from teacher quality.

  • Can we commit future managers to honesty? Article dans une revue:

    In a competitive business environment, dishonesty can pay. Self-interested executives and managers can have incentive to shade the truth for personal gain. In response, the business community has considered how to commit these executives and managers to a higher ethical standard. The MBA Oath and the Dutch Bankers Oath are examples of such a commitment device. The question we test herein is whether the oath can be used as an effective form of ethics management for future executives/managers-who for our experiment we recruited from a leading French business school-by actually improving their honesty. Using a classic Sender-Receiver strategic game experiment, we reinforce professional identity by pre-selecting the group to which Receivers belong. This allows us to determine whether taking the oath deters lying among future managers. Our results suggest « yes and no. » We observe that these future executives/managers who took a solemn honesty oath as a Sender were (a) significantly more likely to tell the truth when the lie was detrimental to the Receiver, but (b) were not more likely to tell the truth when the lie was mutually beneficial to both the Sender and Receiver. A joint product of our design is our ability to measure in-group bias in lying behavior in our population of subjects (comparing behavior of subjects in the same and different business schools). The experiment provides clear evidence of a lack of such bias.

  • Does voting on tax fund destination imply a direct democracy effect? Article dans une revue:

    Does giving taxpayers a voice over the destination of tax revenues lead to more honest income declarations? Previous experiments have shown that giving participants the opportunity to select the organization that receives their tax funds tends to increase tax compliance. The aim of this paper is to assess whether this increase in compliance is induced by the sole fact of giving subjects a choice—a “direct democracy effect”. To that aim, we ask participants to a tax evasion game to choose, in a collective or individual choice setting, between two very similar organizations which provide the same social (ecological) benefits. We elicit compliance for both organizations before the choice is made so as to control for the counter-factual compliance decision. We find that democracy does not increase compliance, and even observe a slight negative effect—in particular for women. Our results confirm the existence of a commitment effect of democracy, leading to favor more the selected organization when it was actively chosen. The commitment effect of democracy is however not enough to overcome the decrease in the level of compliance. Thanks to response times data, we show that prior choice on similar options as compared to a purely random selection weakens the preference for honesty. One important field application of our results is that democracy in tax spending must offer real choices to tax payers to improve compliance.

  • Financial Literacy and French Behaviour on the Stock Market Article dans une revue:

    This article looks back over the different dimensions of financial literacy: theoretical, methodological, empirical and political. The theoretical foundations of the notion of financial literacy are presented with reference to recent contributions by psychological or behavioural economics: « household finance » refers to the concept of financial literacy based on the empirical dead-ends of standard saver theory. This raises the fundamental question as to how to measure and evaluate financial literacy. Here, we are especially interested in the empirical robustness of a standard measure of financial literacy based on three straightforward questions (interest calculations, notion of inflation and risk diversification). Is this measure adequate or do other definitions need to be developed? We use original data from a survey conducted in 2017 that proposes alternative measures. Our results show that the measure in most studies seems a good proxy for a more global measure based on a larger battery of similar questions. Nevertheless, the global measure improves the statistical quality of the measure even though this more sophisticated measure does not statistically significantly improve behavioural regressions.

  • Labour supply, service intensity, and contracts: Theory and evidence on physicians Article dans une revue:

    Based on linked administrative and survey panel data, we analyze the labour supply behaviour of physicians who could adopt either a standard fee-for-service contract or a mixed remuneration (MR) contract. Under MR, physicians received a per diem and a reduced fee for services provided. We present estimates of a structural discrete choice model that incorporates service intensity (services provided per hour) and contract choice into a labour supply framework. We use our estimates to predict (ex ante) the effects of contracts on physician behaviour and welfare, as measured by average equivalent variations. The supply of services is reduced under a MR contract, suggesting incentives matter. Hours spent seeing patients is less sensitive to incentives than the supply of services. Our results suggest that a reform forcing all physicians to adopt the MR system would have substantially larger effects on physician behaviour than were measured under the observed reform. A pure salary (per diem) reform would sharply reduce services but would increase time spent seeing patients.

  • Modelling the number of avoidable new cancer cases in France attributable to alcohol consumption by following official recommendations: a simulation study Article dans une revue:

    Aims To predict the effects of perfect adherence to the French alcohol consumption guidelines, a maximum of 10 standard alcoholic drinks per week with no more than two standard alcoholic drinks per day, during a 36-year period (2014–50). Design This simulation study is an adaption of the Sheffield Alcohol Policy Model. The dose–response relationship between alcohol consumption and alcohol-attributable cancer risks was defined by cancer site-specific risk functions, each modelled as a continuous risk. These estimates were used to compute the potential impact fraction (PIF) associated with alcohol consumption by cancer site. Setting The French general adult population during a 36-year period (2014–50). Participants For the baseline scenario, the current distribution of consumption levels, the counterfactual scenario and perfect adherence to the French alcohol consumption guidelines, we generated for each gender and age group 1000 randomly distributed alcohol consumption values from calibrated group-specific gamma distribution. Measurements The predicted number of new cancer cases among men and women in France between 2015 and 2050 that could have been prevented by following the French government’s alcohol consumption guidelines. Findings The simulation predicted that perfect adherence to the French government’s alcohol consumption guidelines would prevent, on average, an estimated 15 952 cancer cases per year after the PIF reached its full effect, which would have represented 4.5% of new cancer cases in 2015. The number of averted cancer cases over the study period were highest for oral cavity, oropharynx and hypopharynx cancer (respectively, 118 462, 95% CI = 113 803–123 022 and 11 167, 95% CI = 10 149–12 229] for men and women; liver and intrahepatic bile ducts cancer (123 447, 95% CI = 112 581–133 404 and 2825, 95% CI = 2208,4095); colorectal cancer (89 859, 95% CI = 84 651–95 355 and 12 847, 95% CI = 11 545–14 245); and female breast cancer (61 649, 95% CI = 56 330–67 452). Conclusion This simulation study of the French general population predicted that perfect adherence to the French government’s alcohol consumption guidelines (no more than 10 standard alcoholic drinks per week and two per day) would prevent almost 16 000 cancer cases per year.

  • Évaluation médico-économique de l’éducation thérapeutique par une plateforme interactive communautaire, dialyse et transplantation rénale, PIC-R Article dans une revue:

    Introduction L’objectif principal de cet essai randomisé multicentrique (11 centres hospitaliers) est de démontrer l’efficience (analyse coût–utilité) d’une plateforme digitale (DOCMADI©) d’éducation thérapeutique possédant une composante communautaire et destinée aux patients avec IRC stade 5, dialysés ou transplantés, dans le cadre d’une promotion AP–HP, PRME 2015 (ministère de la Santé). Description Randomisation en 3 bras (pas d’accès à la plateforme [G1], accès sans [G2] et avec [G3] fonctionnalités communautaires). Les patients complètent 3 questionnaires en ligne (M0 conditionnant l’inclusion, M9, M18). Méthodes Critère de jugement principal : différence des coûts rapportés à la différence de survie ajustée à la qualité de vie. Critères secondaires : bénéfices cliniques (survie à M18, observance), effet sur l’organisation des soins (appels au service, passages aux urgences, événements indésirables évités), analyse des coûts et conséquences de l’intervention. Résultats Entre 05/2018 et 12/2020, 815 patients ont été randomisés et 539 inclus (G1 = 180, G2 = 189, G3 = 170), dont 78 au stade 5, 67 dialysés et 394 transplantés. Au 01/06/2021, 433 patients ont complété M9 et 323 M18. Les premiers résultats indiquent des freins à l’inclusion liés aux médecins (difficulté de toute étude clinique), aux patients (non-remplissage à M0) et à des problèmes techniques (logiciel ePro). L’utilisation de la plateforme a fortement augmenté en 2020, en particulier lors de la première vague épidémique de COVID-19, validant son intérêt comme outil d’information pour les centres participants. De nombreux « likes », commentaires et questions sur les forums ont permis de mieux comprendre les préoccupations des patients durant la crise sanitaire et validé l’utilité des fonctions sociales. Chiffres clefs d’utilisation de la plateforme pour l’année 2020 : 20 787 pages lues, 4657 téléchargements et jeux-tests joués plus de 1000 fois. Conclusion Les patients ont manifesté leur intérêt pour notre outil. L’analyse coût/utilité prévue en fin d’étude permettra d’évaluer son efficacité médico-économique.

  • How Laws Affect the Perception of Norms: Empirical Evidence from the Lockdown Article dans une revue:

    Laws not only affect behavior due to changes in material payoffs, but they may also change the perception individuals have of social norms, either by shifting them directly or by providing information on these norms. Using detailed daily survey data and exploiting the introduction of lockdown measures in the UK in the context of the COVID-19 health crisis, we provide causal evidence that the law drastically changed the perception of the norms regarding social distancing behaviors. We show that this effect of laws on perceived norms is mostly driven by an informational channel and that the intervention made perceptions of social norms converge to the actual prevalent norm.

  • Footsie, yeah! Share prices and worker wellbeing Article dans une revue:

    Purpose A small literature has shown that individual wellbeing varies with the price of company stock, but it is unclear whether this is due to wealth effects amongst those holding stock, or more general effects on sentiment, with individuals taking rising stock prices as an indicator of improvements in the economy. The authors contribute to this literature by using two data sets to establish the relationship between share prices on the one hand and worker wellbeing on the other. Design/methodology/approach First, the authors use over 20 years of British panel data to show that employee happiness and job satisfaction moves with share prices among those whose pay is partly determined by company fortunes. The authors then examine share price movements and employee stock holding in a single corporation and provide suggestive evidence that an increase in the firm’s stock price increases the well-being of those who belong to its employee share purchase plan (ESPP). These effects are greatest among those making the largest monthly contributions to the program who have the most to gain (or lose) from stock price fluctuations. There is also tentative evidence that the well-being effects of a higher share price are larger for those who hold more shares. Taken together these results suggest that, although stock price movements have little effect on well-being in the population at large, the well-being of those holding stock in their own company rises when the price of that stock is higher, suggesting the effects of share prices work at least partly via changes in wealth. Findings Taken together these results suggest that the wellbeing effects of share prices work at least partly via changes in wealth. Research limitations/implications The authors cannot be certain that the job satisfaction movements they see are causally linked to share plan participation and bonus receipt. Future research might fruitfully examine the mechanisms at play, and whether the effects identified here are linked to differences in employee motivation and effort over the business cycle. Practical implications Firms may wish to consider the appropriateness of linking their workers’ pay to firm performance through share plans or profit shares to establish whether this improves worker wellbeing. Social implications The utility of workers may increase where firms offer some compensation via a share plan or profit share. Originality/value The literature suggests a link between share price movements and worker wellbeing, but the reasons for the link are contested. Using two very different data sources, the authors are able to show that share price increases induce higher worker wellbeing, at least in part, through wealth effects.

  • Illettrisme financier et rationalité de l’épargnant sur le marché boursier Article dans une revue:

    Cet article revient sur les différents aspects du concept de « littératie financière » : politique, théorique, méthodologique et empirique. Les débats et les enjeux sur la culture économique sont apparus au début des années 2000. La recherche académique sur la finance des ménages s’est alors emparée du sujet en s’appuyant sur l’économie psychologique. Se pose alors la question de la mesure de la littératie financière : Big Three ou autres. Pour répondre à ces questions, nous utilisons des données récentes collectées en France (l’enquête FLIP : Financial LIteracy et Patrimoine). La partie comportementale s’intéresse à l’énigme de la participation sur le marché des actions, en étudiant le lien entre littératie financière et demande d’actifs risqués. La préconisation de plus en plus forte à développer des programmes d’éducation financière afin de pallier la faiblesse de la littératie pose alors la question de leur efficacité.

  • Fixing match-fixing: Optimal schedules to promote competitiveness Article dans une revue:

    In the last round of the FIFA World Cup group stage, games for which the outcome does not affect the selection of the qualified teams are played with little enthusiasm. Furthermore, a team that has already qualified may take into account other factors, such as the opponents it will face in the next stage of the competition so that, depending on the results in the other groups and the scheduling of the next stage, winning the game may not be in its best interest. Even more critically, there may be situations in which a simple draw will qualify both teams for the next stage of the competition. Any situation in which the two opposing teams do not play competitively is detrimental to the sport, and, above all, can lead to collusion and match-fixing opportunities. We here develop a relatively general method of evaluating competitiveness and apply it to the current format of the World Cup group stage. We then propose changes to the current format in order to increase the stakes in the last round of games of the group stage, making games more exciting to watch and, at the same time, reducing any collusion opportunities. We appeal to the same method to evaluate a “groups of 3” format which will be introduced in the 2026 World Cup edition as well as a format similar to the one of the current Euro UEFA Cup.

  • Context-dependent outcome encoding in human reinforcement learning Article dans une revue:

    A wealth of evidence in perceptual and economic decision-making research suggests that the subjective assessment of one option is influenced by the context. A series of studies provides evidence that the same coding principles apply to situations where decisions are shaped by past outcomes, that is, in reinforcement-learning situations. In bandit tasks, human behavior is explained by models assuming that individuals do not learn the objective value of an outcome, but rather its subjective, context-dependent representation. We argue that, while such outcome context-dependence may be informationally or ecologically optimal, it concomitantly undermines the capacity to generalize value-based knowledge to new contexts – sometimes creating apparent decision paradoxes.

  • Le marché du travail des footballeuses : vers la professionnalisation ! Article dans une revue:

    Ce numéro de Connaissance de l’emploi est tiré d’un ouvrage (Arrondel et Duhautois, 2020) et montre comment le football féminin est en cours de structuration et tend vers la professionnalisation. Si le football masculin a atteint un certain régime d’équilibre dans son fonctionnement, au niveau de ses compétitions, tant nationales qu’internationales, et de ses clubs, il n’en est pas de même, pour l’instant, du football féminin : ses structures sont encore en évolution. Certains grands pays de football ne se sont lancés que récemment dans la professionnalisation de leur championnat féminin : en Europe, l’Angleterre en 2018 et bientôt l’Italie et l’Espagne (à partir de 2022). Dans ces pays, les clubs masculins les plus connus découvrent seulement aujourd’hui le football féminin. Même si c’est en France que les joueuses sont les mieux payées en moyenne, la professionnalisation au sens strict – gérée et organisée par une ligue – n’y est pas à l’ordre du jour car la Fédération Française de Football (FFF), qui gère le football féminin de haut niveau, ne semble pas vouloir en abandonner la gouvernance. En Asie, la fédération japonaise a également créé une Ligue professionnelle de football féminin en 2021 et l’Australie, en 2019, a fait un grand pas vers cette structure. En Amérique du Sud, la professionnalisation du football féminin a débuté il y a quelques années mais c’est en Amérique du Nord que tout a commencé il y a vingt ans.

  • Measuring resilience to major life events Article dans une revue:

    There is great interest in understanding who in the population is resilient in the face of major life events, and who is not. In this paper we construct a revealed measure of adulthood psychological resilience by modelling individuals’ responses to ten adverse life events using a dynamic finite mixture regression model applied to 17 years of panel data. Our methodology accounts for non-random selection into events, and differences between individuals in anticipation, immediate response, and speed of adaptation. We find considerable heterogeneity in individuals’ responses to events such as major financial shocks, redundancy and bereavement. We also find that our measure of resilience is correlated with clinical measures of mental health, and that it significantly predicts the psychological response to out-of-sample events. The strongest predictor of our measure of resilience is internal locus of control, which is an individual’s belief that life outcomes are under their control.

    Risques écologiques, économiques, politiques et géopolitiques : nos sociétés n’ont jamais été aussi convaincues de s’acheminer vers une série de catastrophes quasiment inévitables. Face à ces dangers, les réactions sont de plusieurs natures. Certains tentent, par des discours prophétiques, de déclencher une mobilisation en pointant des risques particuliers. D’autres proposent une vision plus holiste du fonctionnement du monde qui intègre la possibilité des catastrophes, voire de l’apocalypse. Des groupes survivalistes tentent de se préparer dès à présent au monde postcataclysme. Des juristes proposent, pour les protéger, de donner des droits aux animaux, voire à la nature. Mais en majorité, les « décideurs » peinent à se mobiliser et les sociétés contemporaines semblent s’accommoder des menaces et des « poisons légaux » qu’elles s’infligent. Les études de cas réunies dans cet ouvrage collectif apportent des éclairages inédits aux interrogations d’un monde qui se sent en danger.

Some of the most important methodological advances to have recently been put forward in this field of research are presented. We focus not only on the need to pay particular attention to the accuracy of the estimated effects, but also on the requirement to replicate assessments, carried out by experimentation or quasi-experimentation, in order to distinguish false positives from proven effects.

    We study fairness in economies where humans consume one private good and one public good representing the welfare of other species. We show that a social evaluator cannot be egalitarian with respect to humans while always respecting humans’ unanimous preferences. One solution is to respect unanimous preferences only when doing so does not lead to a decrease in the welfare of other species. Social preferences satisfying these properties reveal surprising connections between concerns for other species, egalitarianism among humans, and unanimity: the latter two imply a form of dictatorship from humans with the strongest preference for the welfare of other species.

  • Market heterogeneity and the distributional incidence of soft-drink taxes: evidence from France Article dans une revue:

    Market heterogeneity may affect the distributional incidence of nutritional taxes if households sort by income across markets with different characteristics. We use scanner data to analyse the distributional incidence of the 2012 French soda tax on Exact Price Indices that measure consumer welfare from the price and availability of softdrinks at a local level. While the average pass-through was small-about 45 per cent-, tax incidence was significantly higher in low-income and less-competitive markets. Market heterogeneity ultimately has substantial distributional effects: it accounts for at least 33 per cent of the difference in welfare variation between low-and high-income consumers.

  • The ‘Eat Well @ IGA’ healthy supermarket randomised controlled trial: process evaluation Article dans une revue:

    Background Successful implementation and long-term maintenance of healthy supermarkets initiatives are crucial to achieving potential population health benefits. Understanding barriers and enablers of implementation of real-world trials will enhance wide-scale implementation. This process evaluation of a healthy supermarket intervention sought to describe (i) customer, retailer and stakeholder perspectives on the intervention; (ii) intervention implementation; and (iii) implementation barriers and enablers. Methods Eat Well @ IGA was a 12-month randomised controlled trial conducted in 11 Independent Grocers of Australia (IGA) chain supermarkets in regional Victoria, Australia (5 intervention and 6 wait-listed control stores). Intervention components included trolley and basket signage, local area and in-store promotion, and shelf tags highlighting the healthiest packaged foods. A sequential mixed-methods process evaluation was undertaken. Customer exit surveys investigated demographics, and intervention recall and perceptions. Logistic mixed-models estimated associations between customer responses and demographics, with store as random effect. Supermarket staff surveys investigated staff demographics, interactions with customers, and intervention component feedback. Semi-structured stakeholder interviews with local government, retail and academic partners explored intervention perceptions, and factors which enabled or inhibited implementation, maintenance and scalability. Interviews were inductively coded to identify key themes. Results Of 500 customers surveyed, 33%[95%CI:23,44] recalled the Eat Well @ IGA brand and 97%[95%CI:93,99] agreed that IGA should continue its efforts to encourage healthy eating. The 82 staff surveyed demonstrated very favourable intervention perceptions. Themes from 19 interviews included that business models favour sales of unhealthy foods, and that stakeholder collaboration was crucial to intervention design and implementation. Staff surveys and interviews highlighted the need to minimise staff time for project maintenance and to regularly refresh intervention materials to increase and maintain salience among customers. Conclusions This process evaluation found that interventions to promote healthy diets in supermarkets can be perceived as beneficial by retailers, customers, and government partners provided that barriers including staff time and intervention salience are addressed. Collaborative partnerships in intervention design and implementation, including retailers, governments, and academics, show potential for encouraging long-term sustainability of interventions.

  • Social Epistemology Chapitre d’ouvrage:

    Social epistemology studies knowledge in social contexts. Knowledge is ‘social’ when its holder communicates with or learns from others (Epistemology in groups), or when its holder is a group as a whole, literally or metaphorically (Epistemology of groups). Group knowledge can emerge explicitly, through aggregation procedures like voting, or implicitly, through institutions like deliberation or prediction markets. In the truth-tracking paradigm, group beliefs aim at truth, and group decisions at ‘correctness’, in virtue of external facts that are empirical or normative, real or constructed, universal or relativistic, etc. Procedures and institutions are evaluated by epistemic performance: Are they truth-conducive? Do groups become ‘wiser’ than their members? We review several procedures and institutions, discussing epistemic successes and failures. Jury theorems provide formal arguments for epistemic success. Some jury theorems misleadingly conclude that ‘huge groups are infallible’, an artifact of inappropriate premises. Others have defensible premises, and still conclude that groups outperform individuals, without being infallible.

  • Pension anticipée et épargne financière des ménages Article dans une revue:

    Depuis l’article pionnier de Feldstein (1974), l’impact d’un système de retraite sur le niveau d’épargne fait l’objet de nombreux travaux aux résultats parfois controversés. Selon l’hypothèse standard du cycle de vie, un individu qui anticipe une perte de niveau de vie à la retraite devrait, toutes choses égales par ailleurs, épargner davantage. C’est à cette question que nous nous intéressons ici. Pour cela, nous considérons que les individus anticipent de façon plus satisfaisante leur taux de remplacement (à partir de leur profil de salaires) qu’un montant de pension au moment du départ en retraite. Nous étudions alors les effets d’une variation anticipée de ce taux de remplacement sur l’épargne financière des ménages, en tenant compte à la fois des évolutions anticipées de carrière et des réformes des retraites. Nous mobilisons la vague2012 de l’enquête PAT€R portant sur la population française qui dispose de riches informations au niveau individuel sur les anticipations de pension. Nos estimations économétriques montrent qu’un plus faible (resp. plus élevé) taux de remplacement anticipé est relié, de façon significative, à un taux d’épargne financière plus élevé (resp. plus faible).

  • Competition between Public and Private Maternity Care Providers in France: Evidence on Market Segmentation Article dans une revue:

    The purpose of this paper is to investigate the potential for segmentation in hospital markets, using the French case where private for-profit providers play an important role having nearly 25% of market shares, and where prices are regulated, leading to quality competition. Using a stylized economic model of hospital competition, we investigate the potential for displacement between vertically differentiated public and private providers, focusing on maternity units where user choice is central. Building over the model, we test the following three hypotheses. First, the number of public maternity units is likely to be much larger in less populated departments than in more populated ones. Second, as the number of public maternity units decreases, the profitability constraint should allow more private players into the market. Third, private units are closer substitutes to other private units than to public units. Building an exhaustive and nationwide data set on the activity of maternity services linked to detailed data at a hospital level, we use an event study framework, which exploits two sources of variation: (1) The variation over time in the number of maternity units and (2) the variation in users’ choices. We find support for our hypotheses, indicating that segmentation is at work in these markets with asymmetrical effects between public and private sectors that need to be accounted for when deciding on public market entry or exit.

  • Homo moralis goes to the voting booth: coordination and information aggregation Pré-publication, Document de travail:

    This paper revisits two classical problems in the theory of voting-viz. the divided majority problem and the strategic revelation of information by majority vote-in the light of evolutionarily founded partial Kantian morality. It is shown that, compared to electorates consisting of purely self-interested voters, such Kantian morality helps voters solve coordination problems and improves the information aggregation properties of equilibria, even for modest levels of morality.

  • Crises de confiance ? Ouvrages:

    Il est communément acquis que la confiance est la vertu élémentaire de toute vie sociale : sans confiance, les conduites de nos semblables seraient imprévisibles et dangereuses, alors qu’elle permet d’anticiper leurs actions et réactions. Mais l’établissement de la confiance repose sur des dispositifs culturels, institutionnels, sociaux et, souvent, imaginaires et religieux. Or, force est de reconnaître que nos sociétés contemporaines sont perturbées par des crises de confiance aux manifestations très diverses : mise en cause des élites politiques, du savoir scientifique et de l’expertise, succès des théories du complot, etc. Dans le même temps, ces crises n’empêchent pas la construction d’autres modalités de la confiance. S’il importe donc d’analyser la manière dont elle est affaiblie, voire détruite, il faut aussi saisir la production continue de la confiance sous des formes nouvelles. Tel est l’objet de cet ouvrage collectif, qui réunit des contributions originales de chercheurs mobilisant nombre de disciplines des sciences humaines et sociales : histoire, anthropologie, psychologie, économie, sociologie, sciences politiques, sciences de la communication… Ces approches plurielles contribuent à éclairer un thème qui embrasse la totalité de la vie des sociétés et peut se décliner en de multiples questions et objets.

  • Party Preference Representation Pré-publication, Document de travail:

    Political parties are key actors in electoral democracies: they organize the legislature, form governments, and citizens choose their representatives by voting for them. How citizens evaluate political parties and how well the parties that citizens evaluate positively perform thus provide useful tools to estimate the quality of representation from the individual’s perspective. We propose a measure that can be used to assess party preference representation at both the individual and aggregate levels, both in government and in parliament. We calculate the measure for over 160,000 survey respondents following 111 legislative elections held in 38 countries. We find little evidence that the party preferences of different socio-economic groups are systematically over or underrepresented. However, we show that citizens on the right tend to have higher representation scores than their left-wing counterparts. We also find that whereas proportional systems do not produce higher levels of representation on average, they reduce variance in representation across citizens.

  • Does the Value per Statistical Life vary with age or baseline health? Evidence from a compensating wage study in France Article dans une revue:

    This paper provides an empirical assessment of the effects of age and baseline health on the Value per Statistical Life (VSL) by reporting the results of a compensating wage differential for occupational fatality risk in France. We exploit Constances, a novel population-based cohort that combines respondents’ full medical history, elicited using face-to-face interviews with physicians, with respondents’ work history, extracted from administrative records. Focusing on blue-collar males, aged between 20 and 59 years of age, we find an average VSL estimate of at least 6.5 million euros. Our results suggest that VSL decreases with age and with better baseline health.

  • Gig Workers During the COVID-19 Crisis in France: Financial Precarity and Mental Well-Being Pré-publication, Document de travail:

    We set out to explore how precarious workers, particularly those employed in the gig economy, balance financial uncertainty, health risks, and mental well-being. We surveyed and interviewed precarious workers in France during the COVID-19 crisis, in March and April 2020. We oversampled gig economy workers, in particular in driving and food delivery occupations (hereafter drivers and bikers), residing in metropolitan areas. These workers cannot rely on stable incomes and are excluded from the labor protections offered to employees, features which have been exacerbated by the crisis. We analyzed outcomes for precarious workers during the mandatory lockdown in France as an extreme case to better understand how financial precarity relates to health risks and mental well-being. Our analysis revealed that three weeks into the lockdown, 56% of our overall sample had stopped working and respondents had experienced a 28% income drop on average. Gig economy drivers reported a significant 20 percentage point larger income decrease than other workers in our sample. Bikers were significantly more likely to have continued working outside the home during the lockdown. Yet our quantitative analysis also revealed that stress and anxiety levels were not higher for these groups, and that bikers in fact reported significantly lower stress levels during the lockdown. While this positive association between being a biker and mental health may be interpreted in different ways, our qualitative data led to a nuanced understanding of the effect of gig work on mental well-being in this population group.

  • Les chartes d’engagements nutritionnels : une analyse économique de l’échec d’un pari théorique Article dans une revue:

    La mise en place du dispositif des chartes d’engagements volontaires de progrès nutritionnels marque un tournant de la politique française de santé nutritionnelle développée depuis 2001 au travers du Plan national nutrition santé (PNNS). La mise en place du PNNS marquait une renaissance des actions de prévention nutritionnelle qui, avec l’entrée dans l’abondance alimentaire, s’étaient peu à peu désintéressées de la population générale pour se focaliser sur des risques concernant des populations spécifiques (personnes âgées, femmes enceintes, etc.). Le PNNS s’appuyait sur un rapport d’expertise du Haut comité de la santé publique de juin 2000, qui hissait la politique de santé nutritionnelle au rang des politiques de lutte contre le tabagisme et l’alcoolisme et justifiait la transformation de l’alimentation en facteur de risque épidémiologique par des évolutions conjointes de l’offre alimentaire (du fait de l’industrialisation et de la mondialisation) et de la demande (les modes de consommation alimentaire) (Hercberg, Tallec, 2000). Alors que le rapport Hercberg-Tallec proposait explicitement d’utiliser des outils visant à réguler le marché afin de « contribuer à l’atteinte des objectifs de santé publique retenus », le premier PNNS (2001-2005) concentrait ses actions sur les seuls consommateurs [1] [1]Concernant l’offre alimentaire, le rapport proposait notamment… . Il s’agissait avant tout d’une politique d’éducation pour la santé, articulée autour de la popularisation des repères nutritionnels (« 5 fruits et légumes par jour ») et de leur diffusion via des campagnes d’information, générales ou ciblées. Par contraste, l’introduction des chartes dans le second PNNS visait à modifier l’offre alimentaire, en escomptant que quelques accords conclus avec des entreprises leaders incitent toutes les entreprises à modifier la qualité de leur offre.

  • Données brutes d’observation de la Convention citoyenne pour le climat Rapport:

    L’expérience de la Convention Citoyenne pour le Climat (CCC), dans laquelle 150 citoyen·nes tiré·es au sort ont travaillé pendant sept sessions de trois jours (plus deux à distance) d’octobre 2019 à juin 2020, et rendu leurs 149 propositions au Président de la République en juin 2020 pour parvenir à « réduire les émissions de gaz à effet de serre d’au moins 40 % d’ici 2030 dans un esprit de justice sociale », est un exercice démocratique inédit tant par son ambition que son ampleur. La CCC a fait l’objet d’un dispositif original de suivi. Suite à un appel à manifestation d’intérêt lancé début septembre 2019 par le Comité de gouvernance, une quarantaine de chercheuses et chercheurs se sont engagé·es individuellement ou par équipe dans l’observation directe de l’ensemble des modalités de travail de la CCC. Ce collectif très pluridisciplinaire a rassemblé des chercheuses et chercheurs en sciences sociales s’intéressant à l’objet même de la Convention – la réduction des émissions de gaz à effet de serre –, à ses modalités et à ses résultats en termes de politiques climatiques ou d’exercice démocratique, aux conditions sociopolitiques de son émergence et de prise en compte de ses résultats, à la capacité de citoyen·nes de juger d’arbitrages sur lesquels butent les politiques ou les expert·es, et aux modalités de leur délibération sur des changements de grande ampleur. L’observation directe des délibérations entre les citoyen·nes à chacune des tables de discussion était couplée avec une enquête quantitative par questionnaires, à chaque session, pour sonder les valeurs des citoyen·nes, leurs attitudes envers le changement climatique et leurs opinions sur des mesures de politique publique, et sur la qualité des échanges dans leur assemblée, avec quelques questions répétées pour saisir les changements dans la durée de la CCC. Dans un esprit d’ouverture des données de recherche au public, l’ensemble des données quantitatives collectées par ce collectif de chercheuses et chercheurs est rendu public. Ces données sont publiées en trois volumes : (A) Données brutes d’observation de la Convention citoyenne pour le climat. Volume A — Une « France en miniature ». Données sociodémographiques issues du tirage au sort (halshs-03910234), et, pour les données issues du dépouillement des questionnaires, (B) Données brutes d’observation de la Convention citoyenne pour le climat. Volume B — La représentativité de la CCC. Comparaison des réponses des citoyens à des questions posées dans des enquêtes nationales (halshs-03961042) et (C) Données brutes d’observation de la Convention citoyenne pour le climat. Volume C — Les réponses de la CCC session par session (ce volume C assemble huit livrets : un par session) (halshs-03961055). Il convient de garder à l’esprit qu’il s’agit de données brutes, sans analyse ni interprétation, elles n’ont donc en aucun cas valeur de résultats. Plusieurs analyses des chercheuses et chercheurs du collectif utilisant ces données ont été publiées en 2022 ou le seront en 2023, en particulier : (1) Giraudet L.-G. et al., 2022, « “Co-construction” in Deliberative Democracy: Lessons from the French Citizens’ Convention for Climate », Humanities and Social Sciences Communications, DOI:10.1057/s41599-022-01212-6, (2) Landemore H., Fourniau J.-M.

  • De la mesure de la qualité à son usage dans la régulation des systèmes de santé Article dans une revue:

    Dans tous les pays développés, la prise en compte de la qualité dans la régulation des systèmes de santé est au cœur des préoccupations des pouvoirs publics. La recherche de l’efficience, aussi nécessaire soit-elle, ne saurait en effet conduire à des ajustements à la baisse de la qualité des soins. La perspective d’utiliser des indicateurs de qualité dans la rémunération des producteurs fait aujourd’hui son chemin, d’autant que les progrès accomplis dans la mesure de la qualité permettent de disposer d’une vaste palette d’indicateurs. En matière de mesure, les évolutions marquantes à l’étranger sont la combinaison d’indicateurs de processus et de résultats d’une part, et d’autre part, le recueil de plus en plus fréquent de la perspective patient, tant pour l’appréciation des résultats de santé que pour l’expérience de la qualité des soins. Quant à la prise en compte explicite de la qualité dans les schémas de rémunération, elle est aujourd’hui effective, avec plus ou moins de succès, dans plusieurs pays à l’étranger. L’objet de cet article est de faire le point sur les développements récents à l’étranger et en France, concernant la mesure de la qualité des soins et sur les perspectives ouvertes par son usage en matière de rémunération des producteurs de soins.

  • Why corporate purpose matters Article dans une revue:

    After several decades in which shareholder value has been promoted as the mostrational goal a corporation should pursue, questions are being raised, doubts are arising, and criticism is becoming louder and louder. Among the alternatives to shareholder value that are emerging, the idea that managers should be attentive to the interests of all stakeholders is gaining ground. In this paper, three questions are ex-amined:• How could shareholder value be so successful? There must be economic mechanisms that make it a prominent option for the organization of the business sector.• What is the contribution of a productive firm to society and how can it be maximized? A firm does benefit many stake-holders, and it is possible to rigorously define the total benefit it brings to them.• How can the stakeholder approach be promoted and implemented concretely in a market economy that puts pressure on most firms to maximize profit rather than focusing on the total surplus generated?

  • Comment lutter contre la fraude fiscale ? Ouvrages:

    L’évasion fiscale est un sujet qui se dérobe aux outils de l’analyse économique traditionnelle. D’une part, comme toute activité illégale, l’évasion fiscale échappe à l’observation du chercheur en même temps qu’elle se dissimule aux autorités : l’analyse empirique de son ampleur, de ses déterminants et de la manière dont différents dispositifs l’affectent est nécessairement très limitée. D’autre part, sur le plan théorique, l’application simple du calcul coût-bénéfice auquel est supposé se livrer le contribuable « rationnel » conduit à un paradoxe : contrairement à une idée largement répandue, les bénéfices de l’évasion fiscale sont tellement élevés, et le risque de sanction est tellement faible, que l’on peut s’étonner qu’elle soit aussi peu pratiquée dans l’ensemble des économies développées. Plutôt que l’évasion fiscale, c’est donc la « soumission fiscale » qui en constitue le pendant, la disposition à payer l’impôt, qu’il convient d’expliquer pour en comprendre les déterminants. Le double défi que posent les décisions d’évasion fiscale à l’analyse économique n’a pu être relevé que très récemment, grâce à l’émergence, au cours des vingt dernières années, d’une nouvelle approche, l’économie comportementale, qui s’appuie sur la psychologie pour mieux comprendre les comportements économiques ; et, conjointement, d’une nouvelle méthode, l’économie expérimentale, qui permet d’étudier empiriquement les comportements économiques sur lesquels il est difficile de collecter des données convaincantes. Cet opuscule rend compte des résultats de ces travaux et présente un panorama des outils de politique fiscale qui s’en dégagent.

  • Messi, Ronaldo, and the Politics of Celebrity Elections: Voting for the Best Soccer Player in the World Article dans une revue:

    It is widely assumed that celebrities are imbued with political capital and the power to move opinion. To understand the sources of that capital in the specific domain of sports celebrity, we investigate the popularity of global soccer superstars. Specifically, we examine players’ success in the Ballon d’Or—the most high-profile contest to select the world’s best player. Based on historical election results as well as an original survey of soccer fans, we find that certain kinds of players are significantly more likely to win the Ballon d’Or. Moreover, we detect an increasing concentration of votes on these kinds of players over time, suggesting a clear and growing hierarchy in the competition for soccer celebrity. Further analyses of support for the world’s two best players in 2016 (Lionel Messi and Cristiano Ronaldo) show that, if properly adapted, political science concepts like partisanship have conceptual and empirical leverage in ostensibly non-political contests.

  • The Confidence Database Article dans une revue:

    Understanding how people rate their confidence is critical for the characterization of a wide range of perceptual, memory, motor and cognitive processes. To enable the continued exploration of these processes, we created a large database of confidence studies spanning a broad set of paradigms, participant populations and fields of study. The data from each study are structured in a common, easy-to-use format that can be easily imported and analysed using multiple software packages. Each dataset is accompanied by an explanation regarding the nature of the collected data. At the time of publication, the Confidence Database (which is available at https://osf.io/s46pr/) contained 145 datasets with data from more than 8,700 participants and almost 4 million trials. The database will remain open for new submissions indefinitely and is expected to continue to grow. Here we show the usefulness of this large collection of datasets in four different analyses that provide precise estimations of several foundational confidence-related effects.

  • Within-season dismissals of football managers: evidence from the French Ligue 1 Pré-publication, Document de travail:

    There have been many studies of the impact of manager turnover on club performance, especially in European leagues. The methodology used and the measures for performance do not seem to affect the results of the different studies. However, studies using a control group have generally had inconclusive results (Scelles and Llorca, 2019). Our paper examines the impact of within-season manager change on club performance using information from the French Ligue 1 over the period 1998-2018. The clubs that change their manager have different characteristics from clubs that do not. Some may be observed (as points before dismissal), and others remain unobservable in the data. We use an empirical method that takes observable differences between clubs into account (through exact matching) and corrects for unobserved characteristics (through difference-in-differences). Our results show that the overall effects of a change of manager on team performance are insignificant, except in the short term where they are positive and statistically significant for the majority at the 10 % level. Decomposing between home and away games, the effect is only positive and significant for home games, suggesting that this would be more the consequence of fan pressure (through satisfaction with a board decision) than any difference in quality between the old and the new manager.

  • Financial literacy and French behaviour on the stock market Pré-publication, Document de travail:

    This article looks back over the different dimensions of financial literacy: theoretical, methodological and empirical. First, the theoretical foundations of the notion of financial literacy are presented with reference to recent contributions by psychological or behavioural economics: “household finance” refers to the concept of financial literacy based on the empirical dead-ends of standard saver theory. This raises the question as to how to measure and evaluate it. Is the “standard” methodology, based on a few straightforward questions (interest calculations, notion of inflation and risk diversification), adequate or do other definitions need to be developed? As is often said, are the French really “useless at finance” ? Is their financial behaviour, in terms of their portfolio choices, affected by it ? And last but not least, how effective are economic education programmes and is a public financial literacy policy required?

  • Living in the Shadow of the Past: Financial Profiles and Well-Being Pré-publication, Document de travail:

    We here consider the link between individual financial profiles over time and well-being, as measured by life satisfaction. We in particular look at annual self-reported financial worsening and improvement information for over 25,000 individuals in Australian panel data from 2002 to 2017. We first find that satisfaction falls (rises) with a contemporaneous major financial worsening (improvement), with worsening having the larger influence. Second, the experience of these financial events in the past continues to be linked to current well-being. Last, only the order of financial-improvement spells relates to well-being: a given number of past years where finances deteriorated has the same association with current well-being whether the deterioration occurred in one continuous spell or was interrupted. We last show that these associations are heterogeneous over the distribution of well-being.

  • Generating comparative evidence on new drugs and devices before approval Article dans une revue:

    Fewer than half of new drugs have data on their comparative benefits and harms against existing treatment options at the time of regulatory approval in Europe and the USA. Even when active-comparator trials exist, they might not produce meaningful data to inform decisions in clinical practice and health policy. The uncertainty associated with the paucity of well designed active-comparator trials has been compounded by legal and regulatory changes in Europe and the USA that have created a complex mix of expedited programmes aimed at facilitating faster access to new drugs. Comparative evidence generation is even sparser for medical devices. Some have argued that the current process for regulatory approval needs to generate more evidence that is useful for patients, clinicians, and payers in health-care systems. We propose a set of five key principles relevant to the European Medicines Agency, European medical device regulatory agencies, US Food and Drug Administration, as well as payers, that we believe will provide the necessary incentives for pharmaceutical and device companies to generate comparative data on drugs and devices and assure timely availability of evidence that is useful for decision making. First, labelling should routinely inform patients and clinicians whether comparative data exist on new products. Second, regulators should be more selective in their use of programmes that facilitate drug and device approvals on the basis of incomplete benefit and harm data. Third, regulators should encourage the conduct of randomised trials with active comparators. Fourth, regulators should use prospectively designed network meta-analyses based on existing and future randomised trials. Last, payers should use their policy levers and negotiating power to incentivise the generation of comparative evidence on new and existing drugs and devices, for example, by explicitly considering proven added benefit in pricing and payment decisions.

  • Are French Football Fans Sensitive to Outcome Uncertainty Article dans une revue:

    The idea that competitive balance increases the utility of fans, and therefore their spending and the revenue of professional clubs, lies at the heart of sports economics in general and the economics of football in particular. This notion of competitive balance is often invoked to explain the decisions of professional leagues to change the rules of competitions or the distribution of TV rights. However, the empirical literature shows that the relationship between competitive balance and fan demand is far from obvious. In this paper, we examine the idea of competitive balance as perceived by football fans. In the case of Ligue 1, it is mainly explained by medium-and long-term uncertainty, while in the case of the Champions League it is more a matter of long-term suspense. But uncertainty over the outcome is far from being the only factor explaining the demand for football since around 30% of fans report that they would always be willing to attend or watch games even in the hypothetical case that there is no suspense left.

  • Feeling good or feeling better? Pré-publication, Document de travail:

    Can people remember correctly their past well-being? We study three national surveys of the British, German and French population, where more than 50,000 European citizens were asked questions about their current and past life satisfaction. We uncover systematic biases in recalled subjective well-being: on average, people tend to overstate the improvement in their well-being over time and to understate their past happiness. But this aggregate figure hides a deep asymmetry: while happy people recall the evolution of their life to be better than it was, unhappy ones tend to exaggerate its worsening. It thus seems that feeling happy today implies feeling better than yesterday. These results offer an explanation of why happy people are more optimistic, perceive risks to be lower and are more open to new experiences.

  • A Natural Experiment on Job Insecurity and Fertility in France Pré-publication, Document de travail:

    Job insecurity can have wide-ranging consequences outside of the labour market. We here argue that it reduces fertility amongst the employed. The 1999 rise in the French Delalande tax, paid by large private firms when they laid off workers aged over 50, produced an exogenous rise in job insecurity for younger workers in these firms. A difference-in-differences analysis of French ECHP data reveals that this greater job insecurity for these under-50s significantly reduced their probability of having a new child by 3.9 percentage points. Reduced fertility is only found at the intensive margin: job insecurity reduces family size but not the probability of parenthood itself. Our results also suggest negative selection into parenthood, as this fertility effect does not appear for low-income and less-educated workers.

    We propose strike mechanisms as a solution to the classical problem of Hurwicz and Schmeidler [1978] and Maskin [1999] according to which, in twoperson societies, no Pareto efficient rule is Nash-implementable. A strike mechanism specifies the number of alternatives that each player vetoes. Each player simultaneously casts these vetoes and the mechanism selects randomly one alternative among the unvetoed ones. For strict preferences over alternatives and under a very weak condition for extending preferences over lotteries, these mechanisms are deterministic-in-equilibrium. They Nash implement a class of Pareto efficient social choice rules called Pareto-and-veto rules. Moreover, under mild richness conditions on the domain of preferences over lotteries, any Pareto efficient Nash-implementable rule is a Pareto-and-veto rule and hence is implementable through a strike mechanism.

  • Financial Literacy in Western Europe Pré-publication, Document de travail:

    Si l’idée de familiariser les individus avec les outils de l’épargne n’est pas nouvelle, c’est surtout depuis le début des années 2000 que le concept moderne de littéracie financière s’est développé chez les économistes. La littérature dans ce domaine, essentiellement empirique, s’est depuis lors considérablement enrichie. C’est aussi à cette période que l’Organisation de coopération et de développement économiques(OCDE) a d’ailleurs lancé son programme d’éducation financière pour développer la culture financière des ménages. L’objectif de cet article est de décrire les programmes de culture financière et d’éducation financière en Europe occidentale:France, Allemagne, Italie, Espagne, Suisse et Pays-Bas. Un premier constat concerne la littéracie financière:à des degrés divers, les résidents de ces pays sont loin d’avoir une forte littéracie. Un deuxième constat concerne l’hétérogénéité de la littéracie financière. Dans tous les pays, la culture financière dépend de l’âge, de l’éducation et du sexe: elle est plus élevée chez les hommes, les personnes âgées et les diplômés. Certains déterminants semblent être plus spécifiques à la culture de chaque pays: l’opinion politique en France, le passé politique en Allemagne (Ouest vs.Est), la zone linguistique en Suisse… Enfin, il apparaît que les programmes d’éducation financière existent en Europe occidentale depuis le milieu des années 2000, probablement proposés de manière plus systématique dans les pays centralisés.

  • Who’ll stop lying under oath? Empirical evidence from tax evasion games Article dans une revue:

    Using two earned income/tax declaration experimental designs we show that only partial liars are affected by a truth-telling oath, a non-price commitment device. Under oath, we see no change in the number of chronic liars and fewer partial liars. Rather than smoothly increasing their compliance, we also observe that partial liars who respond to the oath, respond by becoming fully honest under oath. Based on both response times data and the consistency of subjects when several compliance decisions are made in a row, we show that partial lying arises as the result of weak preferences towards profitable honesty. The oath only transforms people with weak preferences for lying into being committed to the truth.

  • Inégalités socio-économiques et conceptions subjectives du bien-vieillir. Résultats d’une enquête quantitative Article dans une revue:

    Cet article s’intéresse aux conceptions subjectives du « bien-vieillir » chez les plus de 40 ans en France. Nous tentons de mettre au jour les facteurs explicatifs de ces conceptions, en prêtant une attention particulière au rôle du statut socio-économique. Pour cela, nous analysons des données issues d’une enquête quantitative originale menée en 2016 auprès d’environ 1730 adhérents d’une mutuelle. Dans l’ensemble, bien vieillir signifie surtout être satisfait de sa santé, de sa situation financière, de sa vie familiale et de son couple. Les conditions d’existence ont un retentissement sur les conceptions du bien-vieillir. En effet, dans les milieux plus favorisés, bien vieillir est plus souvent synonyme de bonne santé, de sociabilité et de projets, tandis que dans les milieux plus défavorisés, l’accent est davantage porté sur la satisfaction vis-à-vis du logement et de son environnement, ce qui pourrait renvoyer à des conditions d’habitat plus souvent insatisfaisantes et au « choix du nécessaire ».

  • Bien-être au travail – Ce qui compte Ouvrages:

    Le bien-être au travail ne se réduit pas à de simples facteurs individuels et psychologiques. Il tient largement à la structure des entreprises, à leur type de management et à leur climat social, qui peuvent aussi engendrer de grandes souffrances. En s’appuyant sur des recherches récentes, françaises et internationales, l’économiste Claudia Senik met au jour les sources profondes, parfois invisibles, d’un bien-être au travail dont l’impact sur la vie sociale et économique est considérable. Elle passe en revue tous les leviers dont les services de ressources humaines devraient s’emparer pour accroître l’épanouissement professionnel de leurs salariés : autonomie, perspectives de progression, valorisation symbolique des fonctions, transparence des modes de différenciation salariale, etc.

  • The Age U-shape in Europe: The Protective Role of Partnership Pré-publication, Document de travail:

    We here ask whether the U-shaped relationship between life satisfaction and age is flatter for those who are partnered. This is the case in cross-section EU-SILC data, where the drop in life satisfaction from the teens to the 50s is almost four times larger for the non-partnered than for the partnered, whose life satisfaction essentially follows a slight downward trajectory with age. However, the same analysis in three panel datasets (BHPS, SOEP and HILDA) reveals a U-shape for both marital groups, although still somewhat flatter for the partnered than for the non-partnered. We suggest that the difference between the cross-section and panel results reflects compositional effects: there is in particular a significant shift of the relatively dissatisfied out of marriage in mid-life. These composition effects will flatten the U-shape in age for the partnered in cross-section data.

  • Pension anticipée et épargne financière des ménages Article dans une revue:

    Depuis l’article pionnier de Feldstein (1974), l’impact d’un système de retraite sur le niveau d’épargne fait l’objet de nombreux travaux aux résultats parfois controversés. Selon l’hypothèse standard du cycle de vie, un individu qui anticipe une perte de niveau de vie à la retraite devrait, toutes choses égales par ailleurs, épargner davantage. C’est à cette question que nous nous intéressons ici. Pour cela, nous considérons que les individus anticipent de façon plus satisfaisante leur taux de remplacement (à partir de leur profil de salaires) qu’un montant de pension au moment du départ en retraite. Nous étudions alors les effets d’une variation anticipée de ce taux de remplacement sur l’épargne financière des ménages, en tenant compte à la fois des évolutions anticipées de carrière et des réformes des retraites. Nous mobilisons la vague 2012 de l’enquête PAT€R portant sur la population française qui dispose de riches informations au niveau individuel sur les anticipations de pension. Nos estimations économétriques montrent qu’un plus faible (resp. plus élevé) taux de remplacement anticipé est relié, de façon significative, à un taux d’épargne financière plus élevé (resp. plus faible).

  • Impact of Quality-based Procedures on orthopedic care quantity and quality in Ontario Hospitals Pré-publication, Document de travail:

    In 2012 the Ontario Ministry of Health introduced Quality-Based Procedures (QBPs), whereby for a selected set of medical interventions hospitals started to be reimbursed based on the price by volume formula, with the expectation that payments would be subsequently adjusted with respect to hospital performance on quality indicators. From the onset, unilateral hip and knee replacements were included in QBPs, whereas bilateral hip and knee replacements were added in 2014. In complement to QBPs, in 2012 the Health-Based Allocation Model (HBAM) was phased in allowing part of hospital funding to be tied to municipality-level patient and hospital characteristics. Using patient-level data from Canadian Discharge Abstract Database (DAD), we evaluate through a difference-in-difference approach the impact of QBPs/HBAM on the volume and quality of targeted procedures and other types of joint replacements plausibly competing for hospital resources. After controlling for patient, hospital and regional characteristics, we found a signi_cant decrease in acute length of stay associated to QBPs, as well as a marked shift towards patients being discharged home with/without post-operative supporting services. However, evidence with regards to spillover effects and quality improve ment across all joint replacement types is weak. Results are robust to various model specifications, and different estimation techniques, including matching methods and synthetic control groups.

  • A Happy Choice: Wellbeing as the Goal of Government Article dans une revue:

    In this article, we lay out the basic case for wellbeing as the goal of government. We briefly review the history of this idea, which goes back to the ancient Greeks and was the acknowledged ideal of the Enlightenment. We then discuss possible measures on which a wellbeing orientation could be based, emphasising the importance of acknowledging the political agency of citizens and thus their own evaluations of their life. We then turn to practicalities and consequences: how would one actually set up wellbeing-oriented decision-making and what difference should we expect from current practice? We end by discussing the current barriers to the adoption of wellbeing as the goal of government, both in terms of what we need to know more about and where the ideological barriers lay.

  • Undoing Gender with Institutions: Lessons from the German Division and Reunification Article dans une revue:

    Using the 41-year division of Germany as a natural experiment, we show that the German Democratic Republic’s gender-equal institutions created a culture that has undone the male breadwinner norm and its consequences. Since reunification, East Germany still differs from West Germany not only because of its higher female contribution to household income, but also because East German women can earn more than their husbands without having to increase their number of housework hours, put their marriage at risk or withdraw from the labour market. By contrast, the norm of higher male income, and its consequences, are still prevalent in West Germany.

  • Conditions of Existence and Subjective Perceptions of Retirement: Quantitative Evidence from France Pré-publication, Document de travail:

    This article explores subjective perceptions of retirement in France, using original quantitative data on the customers of a not-for-profit insurance company. The sample contains individuals aged 4084, who are either in the labour force (N=923) or retired (N=705). Perceptions of retirement are measured using closed questions on views of the retirement transition (these views can be positive, negative, or neutral) and definitions of retirement (retirement can be interpreted as a period of freedom, boredom, greater risk of precariousness, etc.). Using a number of different social indicators, we examine whether differences in social conditions translate into heterogeneous perceptions. We also investigate whether social differences in perceptions fade away with increasing age. Both working-age individuals and retirees generally have a positive view of the retirement transition and often define retirement as a period of freedom. Perceptions of retirement are shaped by social conditions: a higher level of education and income, greater wealth, better health, and stronger social involvement go hand in hand with rosier perceptions. Moreover, we uncover a strengthening of this social gradient with increasing age. Finally, perceptions are positively correlated with satisfaction in various domains, for retirees.

  • Compensating for Academic Loss: Online Learning and Student Performance during the COVID-19 Pandemic Pré-publication, Document de travail:

    The outbreak of the COVID-19 pandemic has led to widespread school shutdowns, and many schools have opted for education using online learning platforms. Using administrative data from three middle schools in China, this paper estimates the causal effects of online learning on student performance. Using the difference-in-differences approach, we show that online education improves students’ academic achievement by 0.22 of a standard deviation, relative to those who stopped receiving learning support from their school during the COVID-19 lockdown. All else equal, students from a school having access to recorded online lessons delivered by external higher-quality teachers have achieved more progress in academic outcomes than those accessing lessons recorded by teachers in their own school. We find no evidence that the educational benefits of distance learning differ for rural and urban students. However, there is more progress in the academic achievement of students using a computer for online education than that of those using a smartphone. Last, low achievers benefit the most from online learning while there is no significant impact for top students. Our findings have important policy implications for educational practices when lockdown measures are implemented during a pandemic.

  • Marriage as Insurance: Job Protection and Job Insecurity in France Pré-publication, Document de travail:

    Job insecurity is one type of risk that workers face on the labour market. As with any risk, individuals can choose to insure against it. We consider marriage as potential insurance against labour-market risk. The 1999 rise in the French Delalande layoff tax for older workers produced an exogenous rise in job insecurity for younger workers. A difference-in-differences estimation in panel data reveals that this greater job insecurity for the under-50s led to a significant rise in their probability of marriage, and especially with partners who had greater job security, consistent with marriage providing insurance on the labour market.

  • Taking a wellbeing years approach to policy choice Article dans une revue:

    Every day, policy makers must decide whether a policy is desirable. They do so by examining its impact on a range of outcomes. But the problem is how to aggregate these disparate outcomes. For example, as covid-19 cases rise again, some lockdown measures are gradually being reintroduced across the UK. These policy choices will lead to outcomes that are good (such as fewer deaths from covid-19, less commuting, better air quality) and some that are bad (unemployment, income losses, loneliness, domestic abuse). How can policy makers aggregate these disparate effects in order to arrive at an overall assessment? To do so requires a “common currency” with which to measure all the effects. The currency we propose is the change in years of human wellbeing resulting from the policy.

  • Comme les garçons ? L’économie du football féminin Ouvrages:

    Rien dans les 17 règles « conservées » par l’IFAB (International Football Association Board) depuis 1886 ne dit que les femmes ne peuvent pas jouer au football. Certaines sources documentent très tôt le premier match de football féminin, en 1881 à Édimbourg entre une sélection anglaise et une sélection écossaise. Pourtant l’histoire des femmes et du football est loin d’avoir été un long fleuve tranquille : s’il a eu ses heures de gloire après la Première Guerre mondiale, le football féminin est retombé dans l’anonymat jusqu’au milieu des années 1960 avant de redevenir aujourd’hui l’objet de beaucoup d’intérêts, non seulement sportifs, mais aussi politiques et économiques. Au-delà de son succès populaire dans les stades et à la télévision, la dernière Coupe du monde en France en 2019 a peut-être été un tournant dans l’histoire du football féminin. Pour l’instant, comparé à son homologue masculin, ce football demeure une toute petite « affaire » et il est sans doute trop tôt pour évaluer l’héritage économique de ce tournoi mondial. Cette étude vise à fournir des outils d’analyse et des données statistiques permettant de mieux comprendre l’écosystème du football féminin actuel et notamment d’éclairer la question du niveau de rémunération des footballeuses qui a fait polémique dans les médias. – – – – – – – – –

  • The Impact of Terrorism on Well-being: Evidence from the Boston Marathon Bombing Article dans une revue:

    A growing literature has concluded that terrorism affects the economy, yet less is known about its impact on individual welfare. This article estimates the impact of the 2013 Boston marathon bombing on well-being, exploiting representative daily data from the American Time Use Survey and Well-Being Supplement. Using a combined regression discontinuity and differences-in-differences design, with the 2012 Boston marathon as a counterfactual, we find an immediate reduction in well-being of a third of a standard deviation. In particular, happiness declined sharply and negative emotions rose significantly. While the effects do not persist beyond one week, they may entail adverse health and economic consequences.

  • Catastrophic climate change, population ethics and intergenerational equity Article dans une revue:

    Climate change threatens irreversible and dangerous impacts, possibly leading to extinction. The most relevant trade-off then may not be between present and future consumption but between present consumption and the mere existence of future generations. To investigate this trade-off, we build an integrated assessment model that explicitly accounts for the risk of extinction of future generations. Using the class of number-dampened utilitarian social welfare functions, we compare different climate policies that change the probability of catastrophic outcomes yielding an early extinction. We analyse the role of inequality aversion and population ethics. Low inequality aversion and a preference for large populations favour the most ambitious climate policy, although there are cases where the effect of inequality aversion on the preferred policy is reversed. This is due to the fact that a higher inequality aversion both decreases the welfare loss of reducing consumption of the current generation and also decreases the welfare gain of reducing the future risk of extinction.

    En France, l’organisation des régimes de retraite pourrait être considérablement transformée avec la mise en place progressive d’un système universel de retraite par points, sans modification de l’actuel financement par répartition, à compter de l’année 2022. Cette réforme systémique, qui a déjà obtenu une première validation par l’Assemblée nationale le 5 mars 2020 après que le gouvernement ait eu recours à l’article 49.3, a été suspendue dans la foulée par le Président Macron le 16 mars 2020 en raison de la crise de la Covid-19. En conséquence, le devenir de cette réforme centrale du quinquennat est incertain. Quoi qu’il en soit, cette dernière a replacé la question des retraites au cœur du débat public.

  • Anxiety Increases the Willingness the Willingness to Be Exposed to Covid-19 Risk among Young Adults in France Pré-publication, Document de travail:

    The COVID-19 outbreak has generated significant uncertainty about the future, especially for young adults. Health and economic threats, as well as more diffuse concerns about the consequences of COVID-19, can trigger feelings of anxiety, leading individuals to adopt uncertainty-reducing behaviours. We tested whether anxiety was associated with an increase in willingness to be exposed to the risk of COVID-19 infection (WiRE) using an online survey administered to 3,110 French individuals aged between 18 and 35 years old during the lockdown period (April 2020). Overall, 56.5% of the sample declared a positive WiRE. Unemployment was associated with a higher WiRE (+8.2 percentage points (pp); 95% CI +0.9-15.4 pp). One standard deviation increases in income (+1160€) and psychological state anxiety raised the WiRE by +2.7 pp (95% CI: +1.1-4.4 pp) and +3.9 pp (95% CI: +1.6-6.2 pp), respectively. A one standard deviation increase in perceived hospitalisation risk was associated with a -4.1 pp (95% CI: -6.2-2.1 pp) decrease in the WiRE. Overall, our results suggest that both the prospect of economic losses and psychological anxiety can undermine young adults’adherence to physical distancing recommendations. Public policies targeting young adults must consider both their economic situation and their mental health, and they must use uncertaintyreducing communication strategies.

Quand bien même la structure sociodémographique du mini-public constitué est proche de celle de la population générale – ce qui est le cas pour la Convention citoyenne pour le climat (CCC) –, le recrutement peut avoir sélectionné des citoyen·nes présentant des profils de préférences assez différents de la population.

  • Wealth and indebtedness of French households in 2015 Lessons from the European HFCS survey and international comparisons Article dans une revue:

    The success of Thomas Piketty’s 2013 book, Capital in the 21st Century, has put the theme of inequality at the heart of economic policy debates. In addition, the financial crisis of 2008 has changed the behavior of savers, who now favor prudence in their portfolio. Spatio-temporal comparisons of the distribution of wealth and its composition therefore appear essential for analyzing these public policy issues.The European Household Finance and Consumption Survey collects information on household wealth, revenue and consumption habits. Those data enable a better understanding of savings and indebtedness behaviors, as well as an evaluation of financial weaknesses and monetary policy effects.The 2014-2015 wave shows that the concentration of financial assets is higher than that of real estate. Risky and long-term savings are essentially held by wealthy households, but stockholdings remain low.On average, French households claim to have 268,000 euros of assets gross. Half are indebted, on average up to 37,000 euros. The decile of the richest French holds about 46% of the total wealth, the richest percentile, about 15%. Increasing indebtedness essentially concerns wealthy people. Hence, the household situation does not reveal any major risk on financial stability in France.

    This paper is a survey of what we learned from experiments about how innovations in the field of voting are received. Different experimental methods have been used: in the laboratory, on line and in situ. Preferences for voting rules are driven by self-interest, by a quest for simplicity and are also correlated with political attitudes. For most rules, voters show no cognitive barriers to their use, but for more complex rules, serious misunderstanding can appear.

  • The impact of road accidents on the professional trajectories of staff coming to the end of their careers, based on the Gazel cohort Article dans une revue:

    The objective of this paper is to evaluate the short- and medium-term impact of road accidents on the career paths of French electricity board employees (EDF-GDF), with special emphasis on those coming to the end of their professional careers, based on the Gazel cohort for the period 2002–2014. This study analyzes the adaptation strategies developed by firms and victims following such an exogenous shock. It sheds light on the ability of stakeholders to adjust, in a context marked by a political desire to reform retirement, in particular for special arrangements such as those of EDF-GDF. The Gazel database makes it possible to characterize the different types of road accidents in order to analyze their impacts on the changes in the careers paths of professionals coming to the end of their careers. The econometric strategy is based on the difference-in-differences method with propensity score matching. In total, 4,066 people were victims of road accidents during the study period. On average, victims were older, from lower socioeconomic groups, and were more likely to be male. The analysis shows that victims who suffer serious physical or material consequences exit the labor market earlier, likely due to a reclassification mechanism that offers the right to early retirement. Victims of road accidents whose health is not impacted face fewer changes to their career paths.

  • Préférences des ménages et demande d’actions dans la crise : France 2004-2014 Article dans une revue:

    Dans cet article, nous étudions les facteurs individuels expliquant la détention d’actions sous ses différentes formes, et leurs évolutions suite à la crise financière. Il existe trois principaux modes d’investissement dans les actions : acheter des titres en direct ; les acheter par l’intermédiaire de fonds communs de placement ; et enfin souscrire une assurance-vie liée à des fonds (contrats en unité de compte). Ces trois canaux n’impliquent pas les mêmes comportements. En effet, outre les caractéristiques de risque et de rendement, ils diffèrent par leurs coûts de transaction, leurs frais de gestion et leur fiscalité. En conséquence, il n’y a pas de raison a priori de considérer que les décisions de choix de portefeuille des ménages sur ces différents supports sont équivalentes et correspondent aux mêmes caractéristiques des individus. Les données suggèrent que la baisse régulière du taux d’actionnaires observée en France pendant la crise concerne aussi bien la détention directe qu’indirecte d’actions. Seule échappe à cette baisse la détention des contrats d’assurance-vie. Leur diffusion, croissante entre 2004 et 2014, ne peut cependant expliquer la moindre détention des autres produits-actions (pas d’effet de substitution). Les estimations économétriques permettent d’affiner l’analyse et d’identifier les caractéristiques spécifiques des actionnaires en fonction du support choisi : ceux qui investissent directement dans des actions sont plus riches, plus éduqués et relativement moins averses au risque ; ceux qui détiennent des fonds communs de placement sont un peu plus riches mais aussi plus averses au risque que les actionnaires en direct et ne sont pas plus éduqués ; enfin, pour les investissements en actions sur des contrats d’assurance-vie, la position dans le cycle de vie et la catégorie sociale jouent un rôle important, de même qu’une aversion au risque modérée et une préférence faible pour le présent. Les épargnants qui investissent dans des contrats d’assurance-vie le font davantage par prévoyance (financement de leur retraite par exemple) et ne recherchent pas forcément un rendement à court terme de leurs placements. L’information joue aussi un rôle prépondérant : la détention d’actions par les parents influence les décisions d’investissement des enfants. Enfin, une décomposition économétrique (Oaxaca-Blinder) permet de séparer les effets dus à l’évolution des caractéristiques de la population des effets dus aux changements des comportements sur la diminution du nombre d’actionnaires. Le fait que plus des deux tiers de l’effet global ne puisse pas être expliqué par les changements socio-démographiques met en évidence le fort impact de la crise sur les investissements en actions des ménages.

  • The Economics of Diet and Obesity: Understanding the Global Trends Chapitre d’ouvrage:

    In the last several decades obesity rates have risen significantly. In 2014, 10.8% and 14.9% of the world’s men and women, respectively, were obese as compared with 3.2% and 6.4% in 1975. The obesity “epidemic” has spread from high-income countries to emerging and developing ones in every region of the world. The rising obesity rates are essentially explained by a rise in total calorie intake associated with long-term global changes in the food supply. Food has become more abundant, available, and cheaper, but food affluence is associated with profound changes in the nutritional quality of supply. While calories have become richer in fats, sugar, and sodium, they are now lower in fiber. The nutrition transition from starvation to abundance and high-fat/sugar/salt food is thus accompanied by an epidemiological transition from infectious diseases and premature death to chronic diseases and longer lives. Food-related chronic diseases have important economic consequences in terms of human capital and medical care costs borne by public and private insurances and health systems. Technological innovations, trade globalization, and retailing expansion are associated with these substantial changes in the quantity and quality of food supply and diet in developed as well as in emerging and rapidly growing economies. Food variety has significantly increased due to innovations in the food production process. Raw food is broken down to obtain elementary substances that are subsequently assembled for producing final food products. This new approach, as well as improvements in cold chain and packaging, has contributed to a globalization of food chains and spurred an increase of trade in food products, which, jointly with foreign direct investments, alters the domestic food supply. Finally, technological advancements have also favored the emergence of large supermarkets and retailers, which have transformed the industrial organization of consumer markets. How do these developments affect population diets and diet-related diseases? Identifying the contribution of supply factors to long-term changes in diet and obesity is important because it can help to design innovative, effective, and evidence-based policies, such as regulations on trade, retailing, and quality or incentives for product reformulation. Yet this requires a correct evaluation of the importance and causal effects of supply-side factors on the obesity pandemic. Among others, the economic literature analyzes the effect of changes in food prices, food availability, trade, and marketing on the nutrition and epidemiological transitions. There is a lack of causal robust evidence on their long-term effects. The empirical identification of causal effects is de facto challenging because the dynamics of food supply is partly driven by demand-side factors and dynamics, like a growing female labor force, habit formation, and the social dynamics of preferences. There are several important limitations to the literature from the early 21st century. Existing studies cover mostly well-developed countries, use static economic and econometric specifications, and employ data that cover short periods of time unmarked by profound shifts in food supply. In contrast, empirical research on the long-term dynamics of consumer behavior is much more limited, and comparative studies across diverse cultural and institutional backgrounds are almost nonexistent. Studies on consumers in emerging countries could exploit the rapid time changes and large spatial heterogeneity, both to identify the causal impacts of shocks on supply factors and to document how local culture and institutions shape diet and nutritional outcomes.

  • Retirement and Unexpected Health Shocks Pré-publication, Document de travail:

    Is retirement good for your health? This article explores the impact of retirement on unexpected health evolutions. Using data from the annual Household, Income and Labour Dynamics in Australia survey (2001-2014), we construct measures of the mismatch between each person’s expected and actual health evolution (hereafter, “health shocks”). We find that after retirement, the probability of negative shocks decreases and the likelihood of positive health shocks increases, for both genders. These shocks translate into variations of life satisfaction in the same direction (i.e. unexpected positive health shocks increase life satisfaction). Other indicators of mental and physical health taken from the SF-36 vary in the same way, i.e. improve unexpectedly after retirement. By definition, health shocks are immune to the problem of reverse causality that could run from health to retirement. Hence, our findings are consistent with a positive impact of retirement on health.

  • Is cooking still a part of our eating practices? Analysing the decline of a practice with time-use surveys Article dans une revue:

    People now spend less time doing housework in general, and cooking in particular. So is cooking still a central feature of our daily eating practices? This article compares trends in household cooking durations in France and the USA in the period 1985–2010 using time-use surveys and practice theory. We ask how the association between cooking and eating at home has changed over time, and how it has contributed to the decline in the time spent on household cooking. Descriptive statistics show that US households spent 20 minutes less time per day cooking in 2010 than in 1985 (15 minutes less time per day in France). Linear regressions indicate that the association between cooking duration and the number of eating events at home has declined in the USA but not in France. The Blinder-Oaxaca decomposition method points to this fact as the primary reason for the change in cooking time in the USA; in France, decreased cooking time is accounted for primarily by changes in population characteristics. French and American food practices have followed gradually diverging trajectories, with cooking less a feature of eating practices – even at home – in the USA, whereas the association between eating and preparing food at home remains stable in France.

  • Born to Be Mild? Cohort Effects Don’t (Fully) Explain Why Well-Being Is U-Shaped in Age Chapitre d’ouvrage:

    The statistical analysis of cross-section data very often reveals a U-shaped relationship between subjective well-being and age. This paper uses 18 waves of British panel data to try to distinguish between two potential explanations of this shape: a pure life-cycle or aging effect, and a fixed cohort effect depending on year of birth. Panel analysis controlling for fixed effects continues to produce a U-shaped relationship between well-being and age, although this U-shape is flatter for life satisfaction than for the GHQ measure of mental well-being. The pattern of the estimated cohort effects also differs between the two well-being measures and, to an extent, by demographic group. In particular, those born earlier report more positive GHQ scores, controlling for their current age; this phenomenon is especially prevalent for women.

  • Impact d’un choc de santé sur les modes de vie, exploitation de la cohorte Gazel Article dans une revue:

    Dans cet article les auteurs étudient l’impact d’un « choc de santé », c’est-à-dire la survenue brutale d’un accident ayant entraîné un recours aux soins sur la consommation hebdomadaire de tabac, d’alcool ainsi que sur l’Indice de masse corporel (IMC). En utilisant un modèle à effets fixes et des données de panel provenant de la cohorte Gazel, les résultats montrent que le choc de santé a un impact significatif sur ces comportements de santé. Plus précisément, il induit une baisse significative et durable de la consommation de tabac et d’alcool pendant, respectivement, 5 ans et 3 ans, mais n’influence pas l’IMC. Ces résultats sont à mettre en exergue avec ceux des tentatives d’arrêt ou de diminution de la consommation de tabac qui durent, en moyenne, 2,4 mois. Ce qui est 25 fois moins long que la diminution effective suite à un choc de santé. Ainsi, les résultats montrent que subir un choc de santé est un déterminant majeur de la durée de réduction de la consommation de tabac.

    We here consider the relationship between the individual time profile of crime victimisation and sleep quality. Sleep quality worsens with contemporaneous crime victimisation, with physical violence having a larger effect than property crime. But crime history also matters, and past victimisation experience continues to reduce current sleep quality. Last, there is some evidence that the order of victimisation spells plays a role: consecutive years of crime victimisation affect sleep quality more adversely than the same number of years when not contiguous.

    Le mouvement des Gilets jaunes a introduit dans le débat public de nombreuses interrogations sur les inégalités territoriales. La présente Note vise à analyser les déterminants locaux du mécontentement d’une partie de la population. Nous étudions cinq caractéristiques des conditions de vie locale : l’emploi, la fiscalité locale, les équipements privés et publics, l’immobilier et le lien associatif. Nous mesurons l’évolution de ces dimensions au sein de chaque commune au cours des dernières années et analysons leur pouvoir prédictif sur trois symptômes du mal-être : la mobilisation des Gilets jaunes, la variation du taux d’abstention lors des élections présidentielles, ainsi que le mal-être déclaré par les citoyens.

  • Well-being through the Lens of the Internet Article dans une revue:

    We build models to estimate well-being in the United States based on changes in the volume of internet searches for different words, obtained from the Google Trends website. The estimated well-being series are weighted combinations of word groups that are endogenously identified to fit the weekly subjective well-being measures collected by Gallup Analytics for the United States or the biannual measures for the 50 states. Our approach combines theoretical underpinnings and statistical analysis, and the model we construct successfully estimates the out-of-sample evolution of most subjective well-being measures at a one-year horizon. Our analysis suggests that internet search data can be a complement to traditional survey data to measure and analyze the well-being of a population at high frequency and local geographic levels. We highlight some factors that are important for well-being, as we find that internet searches associated with job search, civic participation, and healthy habits consistently predict well-being across several models, datasets and use cases during the period studied.

  • The Social Cost of Carbon: Valuing Inequality, Risk, and Population for Climate Policy Article dans une revue:

    We analyze the role of ethical values in the determination of the social cost of carbon, arguing that the familiar debate about discounting is too narrow. Other ethical issues are equally important to computing the social cost of carbon, and we highlight inequality, risk, and population ethics. Although the usual approach, in the economics of cost-benefit analysis for climate policy, is confined to a utilitarian axiology, the methodology of the social cost of carbon is rather flexible and can be expanded to a broader set of social-welfare approaches.

  • The Economics of Diet and Obesity: Public Policy Chapitre d’ouvrage:

    The rise in obesity and other food-related chronic diseases has prompted public-health officials of local communities, national governments, and international institutions to pay attention to the regulation of food supply and consumer behavior. A wide range of policy interventions has been proposed and tested since the early 21st century in various countries. The most prominent are food taxation, health education, nutritional labeling, behavioral interventions at point-of-decision, advertising, and regulations of food quality and trade. While the standard neoclassical approach to consumer rationality provides limited arguments in favor of public regulations, the recent development of behavioral economics research extends the scope of regulation to many marketing practices of the food industry. In addition, behavioral economics provides arguments in favor of taxation, easy-to-use front-of-pack labels, and the use of nudges for altering consumer choices. A selective but careful review of the empirical literature on taxation, labeling, and nudges suggests that a policy mixing these tools may produce some health benefits. More specifically, soft-drink taxation, front-of-pack labeling policies, regulations of marketing practices, and eating nudges based on affect or behavior manipulations are often effective methods for reducing unhealthy eating. The economic research faces important challenges. First, the lack of a proper control group and exogenous sources of variations in policy variables make evaluation very difficult. Identification is challenging as well, with data covering short time periods over which markets are observed around slowly moving equilibrium. In addition, truly exogenous supply or demand shocks are rare events. Second, structural models of consumer choices cannot provide accurate assessment of the welfare benefits of public policies because they consider perfectly rational agents and often ignore the dynamic aspects of food decisions, especially consumer concerns over health. Being able to obtain better welfare evaluation of policies is a priority. Third, there is a lack of research on the food industry response to public policies. Some studies implement empirical industrial organization models to infer the industry strategic reactions from market data. A fruitful avenue is to extend this approach to analyze other key dimensions of industrial strategies, especially decisions regarding the nutritional quality of food. Finally, the implementation of nutritional policies yields systemic consequences that may be underestimated. They give rise to conflicts between public health and trade objectives and alter the business models of the food sector. This may greatly limit the external validity of ex-ante empirical approaches. Future works may benefit from household-, firm-, and product-level data collected in rapidly developing economies where food markets are characterized by rapid transitions, the supply is often more volatile, and exogenous shocks occur more frequently.

  • Truth Telling Under Oath Article dans une revue:

    Oath-taking for senior executives has been promoted as a mean to enhance honesty within and towards organizations. Herein we explore whether people who voluntarily sign a solemn truth-telling oath are more committed to sincere behavior when offered the chance to lie. We design an experiment to test how the oath affects truth-telling in two contexts: a neutral context replicating the typical experiment in the literature, and a « loaded » context in which we remind subjects that « a lie is a lie. » We consider four payoff configurations, with differential monetary incentives to lie, implemented as within-subjects treatment variables. The results are reinforced by robustness investigations in which each subject made only one lying decision. Our results show that the oath reduces lying, especially in the loaded environment-falsehoods are reduced by fifty percent. The oath, however, have a weaker effect on lying in the neutral environment. The oath did affect decision times in all instances: the average person takes significantly more time deciding whether to lie under oath.

  • Discounting and Intergenerational Ethics Chapitre d’ouvrage:

    The question of social discounting is central in intertemporal cost–benefit analysis that often shapes economists’ recommendations regarding climate policy. The practice of discounting has been the object of heated debates among economists and philosophers, revolving around the issue of intergenerational ethics. In this chapter, the authors review the different arguments for and against specific values of social discounting. The authors show that there are actually two different ethical issues at stake: (1) the question of impartiality (or equal treatment of all generations) and (2) the question of priority to the worse off (aversion to inequality in resources, capabilities, or welfare). These questions have emerged in the utilitarian approach and can be neatly separated in that case. They also have very different consequences for climate policy. The authors then argue that the question of social discounting is not confined to the utilitarian framework as it more generally describes the social value of income (or capability or welfare) transfers to future generations. Lastly, the authors discuss the many limitations of social discounting as a tool for policy analysis.

  • Who Got the Brexit Blues? The Effect of Brexit on Subjective Wellbeing in the UK Article dans une revue:

    We use the 2015–16 waves of the UK Household Longitudinal Study (Understanding Society) to look at subjective wellbeing around the time of the June 2016 EU membership Referendum in the UK (Brexit). We employ measures of both evaluative and affective wellbeing, namely life satisfaction and mental distress, respectively. We find that those reporting lower life satisfaction in 2015 were more likely to express a preference for leaving the EU in 2016, while mental distress was less predictive of pro‐Brexit attitudes. Post‐Referendum, those with Leave preferences enjoyed an increase in life satisfaction but there was no change in average life satisfaction in the overall sample. In contrast, the average level of mental distress increased in the sample post‐ Referendum, with no significant difference between those preferring to remain in or to leave the EU. We test the robustness of our results by considering a number of potential caveats, such as sample selection, unobserved individual fixed effects and the interval between interviews. Overall, our results suggest that levels of subjective wellbeing may be both a cause and a result of the 2016 Brexit vote.

    The paper analyses sequences of penalty kicks during football shoot-outs in French cup competitions. We consider in detail the psychological effects to which the kicker is subject: the fear of winning, the fear of losing, the expected outcomes and how much is at stake. Our main conclusion is that the performance (the probability of scoring) is negatively affected by both what is at stake (the impact of my scoring on the expected probability that my team will eventually win) and the difficulty of the situation (the ex ante probability of my team eventually losing). We find no advantage for the team that takes the first kick.

  • Measuring identity orientations for understanding preferences: a french validation of the aspects-of-identity questionnaire Article dans une revue:

    Concepts and results from the psychological research on identity may provide better under-standing of the formation and dynamics of economic preferences. In this perspective, we propose a French translation of the Aspect of Identity (AIQ-IV) psychometric questionnaire, which measures the orientation of subjective identity along personal, relational, public, and collective dimensions (Cheek and Briggs 1982, 2013). The psychometric validation study checks the internal consistency, as well as the four-dimensional factorial structure, of the questionnaire in a representative sample of French young adults (N=1,118). Exploratory and confirmatory factor analyses of item responses reveal a four-factor structure that corresponds to the personal, relational, public, and collective aspects of identity. Individual responses are found to be stable over time. In addition, while being moderately correlated with related psychological constructs (Self-esteem, Social Self-esteem, Self- consciousness), dimensions of the AIQ also predicts risk, time, and social preferences as measured by Likert scales and hypothetical choices.

  • Impulsivity is associated with food intake, snacking, and eating disorders in a general population Article dans une revue:

    Background Impulsivity is a psychological trait linked to health issues such as obesity. However, few studies have explored the relation between impulsivity, dietary intake, and eating disorders (EDs) in a general population. Objective The aim of this cross-sectional study was to assess whether impulsivity was associated with energy intake, food-group consumption, snacking, and risk of EDs. Design In 2014, 51,368 adult participants from the NutriNet-Santé Study completed the 11th version of the Barratt Impulsiveness Scale (BIS-11), which assesses impulsivity. Food-group consumption and diet quality were evaluated by using ≥3 self-reported 24-h dietary records (n = 35,830), whereas snacking behavior was evaluated by an ad hoc question (n = 48,562). Risk of EDs was assessed with the Sick-Control-One-Fat-Food Questionnaire (SCOFF), and categories of ED (restrictive, bulimic, hyperphagic, and other types of EDs) were determined with the Expali algorithm (n = 48,824). Logistic and linear regressions were used to analyze the associations between impulsivity and energy intake, food-group consumption, diet quality, snacking, and risk of EDs, taking into account sociodemographic and lifestyle factors. Results Positive associations were found between impulsivity and consumption of alcoholic beverages and appetizers, whereas negative associations were found for fruit and vegetables, meat and poultry, processed meat, dairy products, milk-based desserts, and starchy foods. Impulsivity was positively associated with energy intake and negatively associated with diet quality. Impulsivity was also positively associated with snacking (OR: 3.32; 95% CI: 2.99, 3.68) and risk of EDs (OR: 3.02; 95% CI: 2.74, 3.33). The strongest associations were found for bulimic disorders (OR: 4.38; 95% CI: 3.66, 5.23) and hyperphagic disorders (OR: 2.91; 95% CI: 2.56, 3.31). Conclusion Impulsivity was associated with food intakes, snacking, and risk of EDs and could be taken into account in the promotion of healthy eating behavior. This study was registered at clinicaltrials.gov as NCT03335644.

  • Does inequality matter for the consumption-wealth channel? Empirical evidence Article dans une revue:

    This paper studies the heterogeneity of the marginal propensity to consume out of wealth based on French household surveys. This heterogeneity is driven by differences in both wealth composition and wealth levels. We find a decreasing marginal propensity to consume out of wealth across the wealth distribution for all net wealth components. The marginal propensity to consume out of financial assets tends to be higher compared with the effect of housing assets, except at the top of the wealth distribution. The marginal propensity to consume out of housing wealth increases with debt pressure and depends on debt composition.

    Le « jugement majoritaire » est un mode de scrutin par évaluation qui choisit un candidat ayant la meilleure évaluation médiane. L’article est consacré à la question : que fait-on quand on choisit suivant la meilleure médiane ? Ce principe revient à déterminer quelle demi-population négliger pour satisfaire au mieux, dans le sens d’un compromis rawlsien, l’autre moitié. Il apparaît en contradiction avec la définition de la démocratie comme participation de tous, et non de la moitié de la population plus un. De plus, satisfaire au mieux la demi-population la plus facile à satisfaire n’est pas ce que produisent les règles de choix « majoritaires », respectant le principe de Condorcet. Ces règles tendent au contraire à promouvoir les solutions consensuelles, tout particulièrement dans les environnements politiques. Cela explique les résultats surprenants produits par le jugement majoritaire.

  • Undoing Gender with Institutions. Lessons from the German Division and Reunification Pré-publication, Document de travail:

    Social scientists have provided empirical evidence that « gender trumps money », meaning that gender norms can be more powerful than economic rationality in shaping daily arrangements between spouses. In particular, when they deviate from the « male breadwinner » norm, women react by « doing gender », i.e. overplaying their feminine role by increasing the number of housework hours that they accomplish. The risk of divorce also increases when a woman earns more than her husband. This paper shows that, however powerful, these norms are cultural and can be trumped by institutions. We use the 41-year division of Germany as a natural experiment and look at differences between East and West Lander in terms of gender behavior after the German reunification. As most countries of the socialist bloc, the former GDR had designed institutions that were much more gender equalizing than their counterpart in the former FRG. We show that these institutions have created a culture that keeps inuencing behavior up to the current period. In particular, East Germany differs from West Germany in the sense that a woman can earn more than her husband without « doing gender » and without putting her marriage at risk.

  • Market Heterogeneity and the Distributional Incidence of Soft-drink Taxes: Evidence from France Pré-publication, Document de travail:

    Market heterogeneity may affect the distributional incidence of soft-drink taxes if households sort by income across markets with different characteristics. We use the Kantar Worldpanel homescan data to analyse the distributional incidence of the 2012 French soda tax on Exact Price Indices (EPIs) that measure consumer welfare from the price, availability and consumption of Sugar-Sweetened Beverages (SSBs) at a local market level. After correcting prices for consumer heterogeneity in preferences, we find that the soda tax had a significant but small national average impact corres- ponding to a pass-through of approximately 40%. Producers and retailers set significantly higher pass-throughs in low-income, less-competitive and smaller markets and for cheaper but less popular brands. Market heterogeneity ultimately has substantial distributional effects, as it accounts for approximately 35% of the difference in welfare variation between low- and high-income consumers.

Il repose sur la réflexion théorique et sur de nombreuses expériences réalisées en collaboration avec le public, dans les bureaux de vote, en ligne ou en laboratoire. Certaines méthodes envisagées sont plus satisfaisantes que les systèmes actuels, et tendraient sans doute à favoriser les candidats consensuels.En s’interrogeant sur l’art difficile de la décision collective et sur ce que pourrait être notre démocratie, l’ouvrage porte un éclairage original sur ce qu’elle est actuellement, sur ses petits défauts comme sur ses failles plus profondes.

  • Language skills and homophilous hiring discrimination: Evidence from gender and racially differentiated applications Article dans une revue:

    This paper investigates the importance of ethnic homophily in the hiring discrimination process. Our evidence comes from a correspondence test performed in France in which we use three different kinds of ethnic identification: French sounding names, North African sounding names, and « foreign » sounding names with no clear ethnic association. Within the groups of men and women, we show that all non-French applicants are equally discriminated against when compared to French applicants. Moreover, we find direct evidence of ethnic homophily: recruiters with European names are more likely to call back French named applicants. These results show the importance of favoritism for in-group members. To test for the effect of information about applicant’s skills, we also add a signal related to language ability in all resumes sent to half the job offers. The design allows to uniquely identify the effect of the language signal by gender. Although the signal inclusion significantly reduces the discrimination against non-French females, it is much weaker for male minorities.

  • Inégalités socioéconomiques et conceptions subjectives du bien vieillir : Résultats d’une enquête quantitative Pré-publication, Document de travail:

    Cet article s’intéresse aux conceptions subjectives du « bien vieillir » chez les plus de 40 ans en France. Nous tentons de mettre au jour les facteurs explicatifs de ces conceptions, en prêtant une attention particulière au rôle du statut socioéconomique. Pour cela, nous analysons des données issues d’une enquête quantitative originale menée en 2016 auprès d’environ 1730 adhérents d’une mutuelle. Dans l’ensemble, bien vieillir signifie surtout être satisfait de sa santé, de sa situation financière, de sa vie familiale et de son couple. Les conditions d’existence ont un impact sur les conceptions du bien vieillir. En effet, dans les milieux plus favorisés, bien vieillir est plus souvent synonyme de bonne santé, de sociabilité et de projets, tandis que dans les milieux plus défavorisés, l’accent est davantage mis sur la satisfaction vis-à-vis du logement et de son environnement, ce qui pourrait renvoyer à des conditions d’habitat plus souvent insatisfaisantes et au « choix du nécessaire ».

  • Retirement and Unexpected Health Shocks Article dans une revue:

    Is retirement good for your health? We complement previous studies by exploring the effect of retirement on unexpected health evolution. Using panel data from the Household, Income and Labour Dynamics in Australia survey (2001-2014), we construct measures of the mismatch between individual expected and actual health evolution (hereafter “health shocks”). In our approach, reverse causation running from health shocks to retirement is highly unlikely, because we look at shocks that happen after retirement, and those shocks are, by definition, unanticipated. We find that retirement decreases the probability of negative shocks (by approximately 16% to 24% for men and 14% to 23% for women) while increasing the likelihood of positive shocks (by 9% to 14% for men and 10% to 13% for women). This result is robust to the use of different lead-lag structures and of alternative measures of health change. Our findings are thus consistent with a positive impact of retirement on health.

    We here use five rounds of Afrobarometer data covering more than 100,000 individuals over the 2004–2016 period to explore the link between individual self‐reported measures of living conditions and access to four basic needs. We not only consider own access to these needs, but also various indices of their deprivation, satisfaction and inequality. We find some evidence of comparisons to those who are better off and to those who are worse off, in terms of access to basic needs, in the evaluation of current living conditions. Overall, however, subjective living conditions are mostly absolute in African countries. There is notable heterogeneity by level of development, with the effect of lack of access to basic needs being more pronounced in poorer countries. Equally, comparisons to the better off are associated with better living conditions in poorer countries, suggesting the existence of a tunnel effect: this latter disappears with economic development.

  • A Psychometric Investigation of the Personality Traits Underlying Individual Tax Morale Article dans une revue:

    Why do people pay taxes? Rational choice theory has fallen short in answering this question. Another explanation, called “tax morale”, has been promoted. Tax morale captures the behavioral idea that non-monetary preferences (like norm-submission, moral emotions and moral judgments) might be better determinants of tax compliance than monetary trade-offs. Herein we report on two lab experiments designed to assess whether norm-submission, moral emotions (e.g. affective empathy, cognitive empathy, propensity to feel guilt and shame) or moral judgments (e.g. ethics principles, integrity, and moralization of everyday life) can help explain compliance behavior. Although we find statistically significant correlations of tax compliance behavior with empathy and shame, the economic significance of these correlations are low–—more than 80% of the variability in compliance remains unexplained. These results suggest that tax authorities should focus on the institutional context, rather than individual preference characteristics, to handle tax evasion.

  • Précis d’Économie Expérimentale Ouvrages:

    Ce Précis propose un panorama des méthodes expérimentales utilisées en sciences économiques. Ces méthodes ont été développées afin d’observer les comportements adoptés par les « agents économiques » dans des situations qui répliquent celles auxquelles s’intéresse l’économiste ; mais dans un environnement contrôlé. Sur cette base, les outils présentés dans ce précis permettent de tester les prédictions et le contenu empirique de la théorie économique, de faire émerger de nouveaux faits stylisés sur le fonctionnement de situations mal comprises par la théorie, ou encore d’informer l’élaboration des politiques publiques. Cette large palette d’objectifs explique que ces méthodes soient devenues très courantes en économie appliquée, et que leur usage se soit diffusé au-delà de l’économie à des domaines tels que le marketing, la gestion ou encore le management. L’ouvrage présente un traitement détaillé des principaux outils disponibles pour mesurer différents aspects des comportements économiques : les décisions individuelles dans le certain et dans l’incertain, les choix intertemporels, les interactions stratégiques, les préférences sociales et les mécanismes d’allocation de ressources. L’ouvrage présente également les critères méthodologiques qui permettent d’évaluer la pertinence théorique et empirique des données récoltées à partir de ces outils.

  • Jury Theorems Chapitre d’ouvrage:

    We give a review and critique of jury theorems from a social-epistemology perspective, covering Condorcet’s (1785) classic theorem and several later refinements and departures. We assess the plausibility of the conclusions and premises featuring in jury theorems and evaluate the potential of such theorems to serve as formal arguments for the ‘wisdom of crowds’. In particular, we argue (i) that there is a fundamental tension between voters’ independence and voters’ competence, hence between the two premises of most jury theorems; (ii) that the (asymptotic) conclusion that ‘huge groups are infallible’, reached by many jury theorems, is an artifact of unjustified premises; and (iii) that the (non-asymptotic) conclusion that ‘larger groups are more reliable’, also reached by many jury theorems, is not an artifact and should be regarded as the more adequate formal rendition of the ‘wisdom of crowds’.

  • A theory of Bayesian groups Article dans une revue:

    A group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever individual credences undergo Bayesian revision based on this information. To obtain a fully Bayesian group, one should often extend this requirement to non‐public or even private information (learnt by not all or just one individual), or to non‐representable information (not representable by any event in the domain where credences are held). I propose a taxonomy of six types of ‘group Bayesianism’. They differ in the information for which Bayesian revision of group credences is required: public representable information, private representable information, public non‐representable information, etc. Six corresponding theorems establish how individual credences must (not) be aggregated to ensure group Bayesianism of any type, respectively. Aggregating through standard averaging is never permitted; instead, different forms of geometric averaging must be used. One theorem—that for public representable information—is essentially Russell et al.’s central result (with minor corrections). Another theorem—that for public non‐representable information—fills a gap in the theory of externally Bayesian opinion pooling.

  • Quantifying the intangible impact of the Olympics using subjective well-being data Article dans une revue:

    Hosting the Olympic Games costs billions of taxpayer dollars. Following a quasi-experimental setting, this paper assesses the intangible impact of the London 2012 Olympics, using a novel panel of 26,000 residents in London, Paris, and Berlin during the summers of 2011, 2012, and 2013. We show that hosting the Olympics increases subjective well-being of the host city’s residents during the event, particularly around the times of the opening and closing ceremonies. However, we do not find much evidence for legacy effects. Estimating residents’ implicit willingness-to-pay for the event, we do not find that it was worth it for London alone, but a modest well-being impact on the rest of the country would make hosting worth the costs.

  • Intérêt des adhérents d’une mutuelle pour des services utilisant leurs données personnelles dans le cadre de la médecine personnalisée Pré-publication, Document de travail:

    Au cours d’une enquête quantitative menée en 2016 auprès de 1 700 adhérents d’une mutuelle, nous avons mesuré l’intérêt pour différents services qui seraient proposés par la mutuelle et utiliseraient les données personnelles dans une logique de médecine personnalisée. Les répondants sont à la fois préoccupés par la confidentialité de leurs données et intéressés par leur utilisation dans un but de suivi, de prédiction et de prévention. L’intérêt est plus marqué en cas de mauvaise santé et d’inquiétude pour les vieux jours. On observe un intérêt plus faible chez les individus dont la position sociale est plus élevée, peut-être du fait de leurs ressources matérielles et culturelles et de leur préoccupation vis-à-vis des risques liés à l’utilisation des données.

  • Conditions influencing the adoption of a soda tax for public health: Analysis of the French case (2005–2012) Article dans une revue:

    Although over 40 jurisdictions have adopted a tax on sugar-sweetened beverages (SSBs) for public health worldwide, it is still debated in many places. Policy processes can influence the prospect of an SSB tax, its design and its public health benefits. To get an insight into such processes, we undertook a case study of the soda tax enacted in France on the 1st of January 2012. Newspaper articles (2003–2013) and institutional documents (2007–2012) were identified using keywords and search engines. Qualitative data extraction and analyses were performed on a thematic and chronological basis, with guidance from Kingdon’s multiple streams theory (MST). Triangulation was enhanced by using complementary sources. This study shows that in August 2011, the French government surprisingly announced a €3.58 cent/L excise tax on SSBs, excluding juices with no added sugars and non-calorically sweetened beverages (NCSBs). As part of a large budgetary plan, the proposal aimed to reduce SSB consumption and raise revenue that was earmarked for health care. Several conditions contributed to opening a policy window: The announcement occurred in the context of severe budgetary deficits; soda tax scenarios had already been discussed at a high level; and the bill was supported by convinced political leaders. Subsequently, the tax successfully passed through the legislative process due to a series of unexpected events, but its public health rationale and design were weakened. The first event was the disorganised reaction by the food industry, despite their sharp opposition to the tax. The next event was the support of the soda tax that came from a majority of Deputies, provided that the revenues would serve another purpose: relieving wage costs in the farming sector. Finally, policy entrepreneurs favoured a compromise to make the tax politically acceptable and legally viable: The tax rate doubled, the scope was extended to NCSBs and revenues were split between health care and agriculture. This study sheds light on influence factors that could be taken into account by public health actors willing to influence soda tax policy processes.

  • Economic Insecurity and the Rise of the Right Pré-publication, Document de travail:

    Economic insecurity has attracted growing attention in social, academic and policy cir- cles. However, there is no consensus as to its precise de_nition. Intuitively, economic insecurity is multi-faceted, making any comprehensive formal de_nition that subsumes all possible aspects extremely challenging. We propose a simpli_ed approach, and character- ize a class of individual economic-insecurity measures that are based on the time pro_le of economic resources. We then apply our economic-insecurity measure to data on political preferences. In US, UK and German panel data, and conditional on current economic resources, economic insecurity is associated with both greater political participation (sup- port for a party or the intention to vote) and notably more support for parties on the right of the political spectrum. We in particular _nd that economic insecurity predicts greater support for both Donald Trump before the 2016 US Presidential election and the UK leaving the European Union in the 2016 Brexit referendum.

  • The causes and consequences of early-adult unemployment: Evidence from cohort data Article dans une revue:

    We here use the employment-history data from the British Cohort Study to calculate an individual’s total experience of unemployment from the time they left education up to age 30. We show that, conditional on current unemployment, this experience is negatively correlated with the life satisfaction that the individual reports at age 30, so that past unemployment scars. We also identify the childhood circumstances and family background that predict this adult unemployment experience. Educational achievement and good behaviour at age 16 both reduce adult unemployment experience, and emotional health at age 16 is a particularly strong predictor of unemployment experience for women. Both boys and girls reproduce on average their parents’ unemployment, so that adult unemployment experience is transmitted between generations. We uncover evidence of a social-norm effect: children from less-advantaged backgrounds both experience more adult unemployment but are less affected by it in well-being.

  • Preferences over income distribution: Evidence from a choice experiment Article dans une revue:

    Using a choice experiment in the lab, we assess the relative importance of different attitudes to income inequality. We elicit subjects’ preferences regarding pairs of payoff distributions within small groups, in a firm-like setting. We find that distributions that satisfy the Pareto-dominance criterion attract unanimous suffrage: all subjects prefer larger inequality provided it makes everyone weakly better off. This is true no matter whether payoffs are based on merit or luck. Unanimity only breaks once subjects’ positions within the income distribution are fixed and known ex-ante. Even then, 75% of subjects prefer Pareto-dominant distributions, but 25% of subjects engage in money burning at the top in order to reduce inequality, even when it does not make anyone better off. A majority of subjects embrace a more equal distribution if their own income or overall efficiency is not at stake. When their own income is at stake and the sum of payoffs remains unaffected, 20% of subjects are willing to pay for a lower degree of inequality.

  • A Broomean model of rationality and reasoning Article dans une revue:

    John Broome has developed an account of rationality and reasoning which gives philosophical foundations for choice theory and the psychology of rational agents. We formalize his account into a model that di¤ers from ordinary choice-theoretic models through focusing on psychology and the reasoning process. Within that model, we ask Broome s central question of whether reasoning can make us more rational: whether it allows us to acquire transitive preferences, consistent beliefs, non-akratic intentions, and so on. We identify three structural types of rationality requirements: consistency requirements, completeness requirements, and closedness requirements. Many standard rationality requirements fall under this typology. Based on three theorems, we argue that reasoning is successful in achieving closedness requirements, but not in achieving consistency or completeness requirements. We assess how far our negative results reveal gaps in Broome s theory, or de ciencies in choice theory and behavioural economics.

  • Measuring Well-Being and Lives Worth Living Pré-publication, Document de travail:

    We study the measurement of well-being when individuals have hetero- geneous preferences, including di_erent conceptions of a life worth living. When individuals di_er in the conception of a life worth living, the equivalent income can regard an individual whose life is not worth living as being better o_ than an individual whose life is worth living. In order to avoid that paradoxical result, we reexamine the ethical foundations of well-being measures in such a way as to take into account heterogeneity in the conception of a life worth living. We derive, from simple axioms, an alternative measure of well-being, which is an equivalent income net of the income threshold making lifetime neutral. That new well-being index always ranks an individual whose life is not worth living as worse-o_ than an individual with a life worth living.

  • Causal Inference and Impact Evaluation Article dans une revue:

    This paper describes, in a non-technical way, the main impact evaluation methods, both experimental and quasi-experimental, and the statistical model underlying them. In the first part, we provide a brief survey of the papers making use of those methods that have been published by the journal Economie et Statistique / Economics and Statistics over the past fifteen years. In the second part, some of the most important methodological advances to have recently been put forward in this field of research are presented. To finish, we focus not only on the need to pay particular attention to the accuracy of the estimated effects, but also on the requirement to replicate evaluations, carried out by experimentation or quasi-experimentation, in order to distinguish false positives from proven effects.

  • The Value of a Life-Year and the Intuition of Universality Pré-publication, Document de travail:

    When considering the social valuation of a life-year, there is a conflict between two basic intuitions: on the one hand, the intuition of universality, according to which the value of an additional life-year should be universal, and, as such, should be invariant to the context considered; on the other hand, the intuition of complementarity, according to which the value of a life-year should depend on what this extra life-year allows for, and, hence, on the quality of that life-year, because the quantity of life and the quality of life are complement to each other. This paper proposes three distinct accounts of the intuition of universality, and shows that those accounts either conflict with a basic monotonicity property, or lead to indifference with respect to how life-years are distributed within the population. Those results support the abandon of the intuition of universality. But abandoning the intuition of universality does not prevent a social evaluator from giving priority, when allocating life-years, to individuals with the lowest quality of life.

  • The impact of institution use on the wellbeing of Alzheimer’s disease patients and their caregivers Article dans une revue:

    In France, temporary institutionalization solutions for dependent elders have been encouraged since the early 2000s. They are targeting patients who are maintained at home, but may need temporary solutions to adjust the constraints of caregivers, e.g. to facilitate transitions between several informal care providers or to allow informal caregivers to leave for holidays. However, the influence of these solutions on dependent elders and their caregivers has not been explored yet. We use French longitudinal data (REAL.FR, 686 elders and their primary caregivers followed between 2000 and 2006) to explore the impact of institution placement on the wellbeing of both Alzheimer’s disease patients and their primary informal caregivers. The data distinguishes permanent placements in institution from temporary stays. Using fixed-effect models, we quantify the change in patients’ quality of life and caregivers’ burden of care following the placement of patients. We find that permanent and temporary stays are associated with a decrease in informal caregivers’ burden. However, only permanent stays lead to an improvement of patients’ quality of life. Hence, taken together, the results suggest that while long-run placements may maximize the wellbeing of all the members of a household (patient and caregiver), this is not necessarily the case of short-term placements.

  • The Incidence of Soft-Drink Taxes on Consumer Prices and Welfare: Evidence from the French ” Soda Tax Pré-publication, Document de travail:

    The behavioural impact and acceptability of soft-drink taxes depend crucially on their incidence on consumer prices and welfare across socio-economic groups and markets. We use KantarWorldpanel homescan data to analyse the incidence of the 2012 French soda tax on Exact Price Indices (EPI) measuring consumer welfare from the availability and consumption of Sugar-Sweetened Beverages (SSB) and Non-Calorically Sweetened Beverages (NCSB) at a local geographical level. The soda tax has had significant, similar but small impacts on the EPI of SSB and NCSB (+4%), corresponding to an aggregate pass-through of about 40%. Tax incidence was slightly higher for low-income and high-consuming households. Retailers set higher pass-throughs in low-income, less-competitive and smaller markets. They did not change their product assortments. The lack of horizontal competition in low-income markets had a sizeable effect on tax regressivity. Finally, the negative income gradient in tax incidence was offset by a positive gradient in expected health benefits.

  • Math, Girls and Socialism Pré-publication, Document de travail:

    This paper argues that the socialist episode in East Germany, which constituted a radical experiment in gender equality in the labor market and other instances, has left persistent tracks on gender norms. We focus on one of the most resilient and pervasive gender gaps in modern societies: mathematics. Using the German division as a natural experiment, we show that the underperformance of girls in math is sharply reduced in the regions of the former GDR, in contrast with those of the former FRG. We show that this East-West difference is due to girls’ attitudes, confidence and competitiveness in math, and not to other confounding factors, such as the difference in economic conditions or teaching styles across the former political border. We also provide illustrative evidence that the gender gap in math is smaller in European countries that used to be part of the Soviet bloc, as opposed to the rest of Europe. The lesson is twofold: (1) a large part of the pervasive gender gap in math is due to social stereotypes; (2) institutions can durably modify these stereotypes.

  • Transmitting “values” between generations: Like father, like son? Article dans une revue:

    This text offers a survey of the various studies concerning the degree of intergenerational wealth mobility. The set of measurements established by the various authors makes it possible to judge the magnitude of wealth inequality transmission in different societies. Beyond any material intergenerational transfers (inheritance and gifts), some studies take into account the transmission of other characteristics: Education, income, preferences, genes, etc. to explain the degree of mobility. Most econometric studies of intergenerational wealth mobility reveal that parents’ wealth has a significant effect on their offspring’s wealth. The extent of this immobility depends on the country, time period, and data used, but also on the levels of wealth. The intergenerational elasticity of wealth is probably higher among the rich (around 0.70), than in the rest of the population, where it rarely exceeds 0.50. In other words, having parents twice as rich as their generational average allows a child be 50% more wealthy compared to their own.

  • From degrees of belief to binary beliefs: Lessons from judgment-aggregation theory Article dans une revue:

    What is the relationship between degrees of belief and binary beliefs? Can the latter be expressed as a function of the former – a so-called “belief-binarization rule” – without running into difficulties such as the lottery paradox? We show that this problem can be usefully analyzed from the perspective of judgment-aggregation theory. Although some formal similarities between belief binarization and judgment aggregation have been noted before, the connection between the two problems has not yet been studied in full generality. We seek to fill this gap. This paper is organized around a baseline impossibility theorem, which we use to map out the space of possible solutions to the belief-binarization problem. Our theorem shows that, except in limiting cases, there exists no belief-binarization rule satisfying four initially plausible desiderata. Surprisingly, this result is a direct corollary of the judgmentaggregation variant of Arrow’s classic impossibility theorem in social choice theory.

    Le 26 octobre 1863 au Freemasons’ Tavern du Lincoln’s Inn Fields de Londres, dix-sept représentants des public schools anglaises se réunirent pour unifier les règles du football qui variaient alors d’un collège à l’autre. Ces représentants n’étaient pas conscients d’écrire l’un des chapitres importants de l’histoire populaire moderne. Treize représentants ont voté en faveur des treize lois qui unifièrent les règles du football association dont la règle 11 à l’origine de la discorde : “Un joueur ne peut passer la balle à un autre à la main” (les quatre votants contre participeraient ensuite à la création du rugby). Ces précurseurs imaginaient-ils qu’un siècle et demi plus tard, la terre entière assiste à une finale de la Coupe du monde ? Comment est-on passé d’une pratique sportive destinée à la formation des futures élites anglaises, ou en France à une pratique de patronage, à ce “business universel” ? Cet ouvrage s’intéresse au football de l’ère dite “post-moderne”, celle qui débute dans les années 1990 avec l’arrêt Bosman, l’explosion des droits TV, l’arrivée des milliardaires et des Etats dans l’univers du ballon rond. L’objectif est d’éclairer le débat sur l’argent du football en sortant des discours convenus. Le montant des transferts et des salaires des footballeurs durant l’été 2017 n’ont en effet pas manqué de susciter de fortes critiques et des commentaires catastrophistes : la “bulle” des transferts va exploser ; le “boom” économique du football mènera au “krach” et à la “crise” ; le modèle économique du football n’est pas “durable”… Ces critiques et ces craintes sont-elles fondées ? Est-ce vraiment la fin du football comme certains le prétendent ?

  • Association between time perspective, food choice motives, and food intake in a general population Article dans une revue:

    Improving food choices represents a major goal for the environment and public health. Consideration of future consequences (CFC) is a psychological construct that distinguishes individuals who adopt behaviors based on immediate needs and concerns from individuals who consider the future implications and consequences of their behavior. The objective of this study was to assess the association between CFC and indicators of dietary behaviors such as food choice motives, food intake, diet quality, and snacking. A sample of 50,955 participants from the NutriNet-Santé study completed the CFC-12 questionnaire. Food choice motives were assessed using a validated questionnaire regrouping 9 food choice motives. Food intake and diet quality (mPNNS-GS) were evaluated with of 24-h dietary records, and snacking frequency by using an ad-hoc question. Linear and logistic regressions adjusted for socio-demographic factors were performed. CFC was associated with all food choice motives (p<.0001), with the strongest associations observed for “environmental limitations” and “health” motives. CFC was also associated with intake of 13 out of the 16 food groups (p<.02). The strongest positive associations were found for fruits and vegetables and whole-grain products, while the strongest negative associations were found for alcohol and meat. Overall, CFC was positively associated with diet quality (p<.0001) and negatively associated with snacking frequency (p<.0001). Our data suggest that future-oriented individuals are concerned by their future individual health and also by more distal and altruistic environmental goals.

  • Sincere voting, strategic voting : A laboratory experiment using alternative proportional systems Chapitre d’ouvrage:

    Strategic voting is classically defined as voting for one’s second preferred option to prevent one’s least preferred option from winning when one’s first preference has no chance. Voters want their votes to be effective, and casting a ballot that will have no influence on an election is undesirable. Thus, some voters cast strategic ballots when they decide that doing so is useful.This edited volume includes case studies of strategic voting behavior in Israel, Germany, Japan, Belgium, Spain, Switzerland, Canada, and the United Kingdom, providing a conceptual framework for understanding strategic voting behavior in all types of electoral systems. The classic definition explicitly considers strategic voting in a single race with at least three candidates and a single winner. This situation is more common in electoral systems that have single-member districts that employ plurality or majoritarian electoral rules and have multiparty systems. Indeed, much of the literature on strategic voting to date has considered elections in Canada and the United Kingdom. This book contributes to a more general understanding of strategic voting behavior by taking into account a wide variety of institutional contexts, such as single transferable vote rules, proportional representation, two-round elections, and mixed electoral systems.

  • La dynamique des patrimoines des ménages selon l’âge et la génération en France et dans la zone euro Article dans une revue:

    Le vieillissement démographique, conséquence conjointe de la baisse de la fécondité et de l’allongement de la durée de vie, est susceptible d’influencer en amont les comportements d’épargne des ménages, notamment dans un contexte de réforme du système de retraite public et d’une politique « d’activation » des individus. Par ailleurs, le patrimoine d’une population vieillissante aura une structure particulière, vraisemblablement moins axée sur les actifs risqués. Une question sous-jacente concerne alors la disponibilité de ce patrimoine pour financer l’économie : c’est le sens de la réforme voulue par la récente loi Pacte, visant en particulier à orienter l’épargne retraite vers les produits de fonds propres (actions) plutôt que vers des produits de taux (fonds euros). Aussi, convient-il d’étudier en quoi le niveau et la structure du patrimoine diffèrent en fonction de l’âge et de la génération des ménages. Dans la mesure où ces choix sont également susceptibles de dépendre de l’environnement institutionnel (système de retraite notamment) et du corpus fiscal, portant à la fois sur les plus-values, les produits financiers mais aussi les successions, il importe d’inscrire cette réflexion dans un contexte international. Ce texte porte un éclairage particulier sur la France, mais propose donc des comparaisons avec les principales économies européennes. Les données montrent que la distribution du patrimoine, total ou financier, s’est déformée depuis 30 ans au profit des vieilles générations. Par ailleurs, depuis 2008, la structure de l’épargne des Français est de plus en plus prudente, de moins en moins tournée vers les actifs risqués. D’un point de vue macroéconomique, ces éléments appellent à une meilleure allocation de l’épargne des particuliers vers des produits davantage susceptibles de financer l’économie, un des objectifs de la récente loi Pacte.

  • Ownership and Hospital Behaviour: Employment and Local Unemployment Pré-publication, Document de travail:

    In this paper, we address two issues: i) how hospital employment changes with local unemployment, according to the type of hospital ownership, and ii) whether this relationship changed after the implementation of a pro-competitive reform that made hospitals more similar. A 2006-2010 French panel of 1,695 hospitals over five waves allows us to consider within-hospital employment changes. We first find that higher local unemployment is associated with greater employment in State-owned hospitals, but not for any other hospital ownership type: French local authorities then seem to respond to depressed local labour markets by increasing employment in State-owned hospitals.

Theoretically, the new reimbursement system should break the relationship between public-hospital employment and local unemployment.

However, in higher-unemployment areas, public-hospital employment remains 2 counter-cyclical. Poor local labour-market health then seems to trump financial incentives in determining employment in public hospitals.

  • Financial Literacy and Asset Behaviour: Poor Education and Zero for Conduct? Article dans une revue:

    Financial Literacy is a specific component of human capital which allows individual to deal with fundamental financial issues so as to take adequate financial decisions. After presenting the theoretical foundations of this notion, establishing its definition and reviewing the empirical literature, this paper presents recent studies about the link between financial literacy and financial decisions of the population in France using an original survey. The results suggest that financial literacy varies across the population. It is correlated with education but also with gender, age and political affiliation. This last point could reflect differences in opinion regarding the role of welfare state and individual responsibility. Finally, the link between financial literacy and some financial behaviors (the propensity to formulate a specific financial plan in the long run on the one hand and the propensity to own stocks on the other hand) is evaluated: in both cases positive correlations with financial literacy variables are found. We conclude with a reflection on the relative status of financial education to explain the investments of households and judge the effectiveness of training programs in the economic culture.

  • Front-of-pack Nutri-Score labelling in France: an evidence-based policy Article dans une revue:

    Since Oct 31, 2017, a front-of-pack labelling system named Nutri-Score (a synthetic information system based on colours and letters from green/A to red/E), allowing consumers to see and compare at a glance the nutritional value of pre-packaged foods is being implemented, on a voluntary basis, in France.1 Although some experts warned that the Nutri-Score might constitute an obstacle to EU trade,2 the measure appeared justified on public health grounds. The adoption of the Nutri-Score label was made after a lengthy 4 year process, during which intense lobbying by agro-industry opposed scientific evidence.

  • Unfairness at work: Well-being and quits Article dans une revue:

    We here consider the effect of the level of income that individuals consider to be fair for the job they do, which we take as measure of comparison income, on both subjective well-being and objective future job quitting. In six waves of German Socio-Economic Panel data, the extent to which own labour income is perceived to be unfair is significantly negatively correlated with subjective well-being, both in terms of cognitive evaluations (life and job satisfaction) and affect (the frequency of feeling happy, sad and angry). Perceived unfairness also translates into objective labour-market behaviour, with current unfair income predicting future job quits.

  • Les attentes en termes de services pour les seniors : le rôle de l’altruisme et de l’anticipation de la dépendance Article dans une revue:

    Dans le contexte du vieillissement de la population, cet article s’intéresse aux attentes en termes de nouveaux services qui pourraient faciliter le bien vieillir en France. À partir de données originales sur les adhérents d’une mutuelle, nous nous concentrons sur les attentes relatives à sept types de services (services liés à la vie sociale, à la santé et aux soins, entre autres) et étudions leurs déterminants. Nos analyses montrent que l’altruisme, la solidarité et l’anticipation de la dépendance jouent un rôle significatif dans ces attentes.

  • Ownership and hospital behaviour: Employment and local unemployment Article dans une revue:

    In this paper, we address two issues: i) how hospital employment changes with local unemployment, according to the type of hospital ownership, and ii) whether this relationship changed after the implementation of a pro-competitive reform that made hospitals more similar. A 2006–2010 French panel of 1695 hospitals over five waves allows us to consider within-hospital employment changes. We first find that higher local unemployment is associated with greater employment in State-owned hospitals, but not for any other hospital ownership type: French local authorities then seem to respond to depressed local labour markets by increasing employment in State-owned hospitals. After the full implementation of the pro-competitive reform hospital funding became based only on activity and no longer on some historical budget. Theoretically, the new reimbursement system should break the relationship between public-hospital employment and local unemployment. Our results reveal that the reform worked as expected in less-deprived areas: reducing employment and eliminating the correlation between local unemployment and State-owned hospital employment. However, in higher-unemployment areas, public-hospital employment remains counter-cyclical. Poor local labour-market health then seems to trump financial incentives in determining employment in public hospitals.

  • Les Français, le bonheur et l’argent Ouvrages:

    Bonheur, satisfaction dans la vie, confiance et optimisme : où en sont les Français ? Il existe une spécificité française en matière de bien-être et ce livre met en lumière plusieurs paradoxes.Les Français se disent moins heureux et plus pessimistes que la plupart des citoyens des autres pays européens ; ce mal-être concerne avant tout les questions économiques ; et c’est en France que la relation entre bonheur et argent est la plus forte. Ceci vient sans doute de leur défiance vis-à-vis des institutions : ne pouvant plus compter sur elles pour organiser leur destinée collective et les protéger contre les principaux risques de la vie, les Français se replieraient sur leurs ressources personnelles. Au malheur collectif s’oppose alors un bonheur privé.Mal-être et défiance se traduisent par un processus de polarisation politique, avec la montée de l’extrême droite notamment. Lors des dernières élections présidentielles, le vote en faveur d’Emmanuel Macron ou de Marine Le Pen a marqué le clivage entre optimistes et pessimistes. Quelle que soit sa postérité, le sursaut d’optimisme du mois de juin 2017 montre que, même si l’état d’esprit des Français est si ancien qu’il finit par se confondre avec une attitude culturelle, il n’est pas pour autant irréversible.

  • Demand For Stocks in the Crisis: France 2004-2014 Pré-publication, Document de travail:

    In this paper, we assess how the factors explaining the holdings of stocks have evolved through the financial crisis. We rely on the data collected in surveys conducted among French households during the period 2004-2014. There are three main modes for investing in stocks: buying shares directly; purchasing them through mutual funds; and finally taking out unitlinked life insurance. Obviously, these three ways to invest in stocks do not involve the same investment behaviours since, besides the risk and return characteristics, they differ in their transaction costs, management fees and taxation. As a result, there is no a priori reason to consider that portfolio choice decisions by households on these modes of stockownership are equivalent and correspond to the same individuals’ characteristics. We show that the holding of risky assets and of individual direct shares decreased during the period, and especially between 2009 and 2014. At the end of the period, the profile of direct equity holders was refocused towards profiles with greater risk tolerance. Other factors of direct stockholdings include: better education, gifts and inheritances, parents holding securities, singles, high-wealth households and high-income groups. Conditionally on holdings, the proportion of risky assets increases with risk tolerance and the holding of securities by parents. It also decreases at the end of the period. Our paper also shows that shareholders have gradually moved towards preferential ownership of shares in life insurance rather than direct share ownership, especially between 2009 and 2014. The estimation of a simultaneous model shows the specific characteristics of stockholders depending on the chosen support (direct, indirect or on life insurance): those who invest directly in stocks are richer, more educated and less risk averse; those who hold mutual funds are a little richer but more risk averse and do not appear the most educated; finally, for ownership in stocks on life insurance contracts, the position in the life cycle plays an important role as well as the social category.

  • Early Access Schemes and Pricing Strategies: A Case Study on Temporary Authorization for Use in France from 1994 to 2016 Article dans une revue:

    Early access schemes for pharmaceuticals have been increasingly implemented worldwide with the objective of satisfying unmet medical needs or facilitating market access for certain innovative drugs. It allows for pharmaceuticals which have not yet obtained their marketing authorization (MA) to be administered and reimbursed to a pre-defined population of patients. Under the French regulatory framework, this scheme consists in a window of unregulated prices, which stands in contrast with the system of administered prices for reimbursed pharmaceuticals. Our study aims at filling a gap in the literature by analyzing the French Temporary Authorization for Use (TAU) scheme since its implementation in 1994 up to 2016. This long time span allows to document and describe the TAU scheme and its impact on prices. In this article, we review the price difference between the freely set price under TAU and the post-MA price, after negotiation with the French Pricing Committee. Our main result shows that the 2007 regulatory change, which compelled pharmaceutical companies to reimburse the difference between the TAU price and the post-MA price, is significantly correlated with decreasing or stable post-MA-to-TAU price ratios.

  • Impact of Diagnosis Related Group Refinement on the Choice Between Scheduled Caesarean Section and Normal Delivery: Recent Evidence from France Pré-publication, Document de travail:

    Studying quasi-experimental data from French hospitals from 2010 to 2013, we test the effects of a considerable diagnosis related group (DRG) refinement that occurred in 2012. As a result, the reform had a direct impact on hospital-level financial incentives but did not immediately concern individual providers. Using a difference-in-differences approach, controlling for multiple patient, hospital and regional characteristics and allowing for hospital and year effects, we show that introducing new severity levels and clinical factors into the reimbursement algorithm had no significant effect on the probability of a scheduled C-section being performed. The results are robust to multiple formulations of financial incentives, to restricting the sample to bigger (>15%) DRG tariff incentive changes and to analyzing policy effects for individual years following the reform. Our results suggest that the DRG refinement did not lead to a transmission of hospital-level stimuli to midwifes and obstetricians. Our paper is the first study that focuses on the consequences of DRG refinement in obstetrics and develops an approach suitable for measuring monetary incentives in this setting.

  • Social Capital or Education: What Matters Most to Cut Time to Diagnosis? Pré-publication, Document de travail:

    Time to diagnosis, defined as the time span from first symptoms to final diagnosis, has received little if no attention, although it is perceived as highly variable across conditions, patients and countries and as a key determinant of health prognoses and outcomes. In this paper, we offer one of the first measures of time to diagnosis for four chronic conditions (bipolar trouble, Crohn disease, multiple sclerosis and psoriasis), and analyze the role played by patients education and social networks in explaining time to diagnosis. Adopting a patient’s perspective, we use self-reported data from an online open access questionnaire administered to a large French social network of patients with chronic conditions. Duration models are used to explain variations in time to diagnosis. Our findings suggest that social participation and social support indeed reduce the probability of experiencing longer time spans to diagnosis. But contrary to expectations, higher levels of education have the reverse effect. We further analyze these results by identifying differences in patients’ health care-seeking behavior: more educated patients tend to consult specialists first, which leads to longer time spans to diagnosis as they are less prone than GPs to referring patients to hospitals for additional tests, when needed. While our social networks findings support WHOs recommendations to enhance individual social capital, results on education provide support for reforms aimed at implementing GP referral systems.

  • The Economics of Malaria Prevention Chapitre d’ouvrage:

    Malaria is a potentially life-threatening disease transmitted through the bites of female anopheline mosquitos infected with protozoan parasites. Malaria remains one of the major causes of mortality by infectious disease: in 2015, there were an estimated 212 million cases and 429,000 deaths globally, according to the 2016 World Malaria Report. Children under 5 years in sub-Saharan Africa bear the greatest burden of the disease worldwide. However, most of these cases could be prevented or treated. Several methods are highly effective in preventing malaria: in particular, sleeping under an insecticide-treated mosquito net (ITN), indoor residual spraying (IRS), and taking intermittent preventive treatment for pregnant women (IPTp). Regarding treatment, artesiminin-based combination therapy (ACT) is recommended as first-line treatment in many countries. Compared with other actions, malaria prevention behaviors have some specific features. In particular, they produce public health externalities. For example, bed net usage creates positive externalities since bed nets not only directly protect the user, but also reduce transmission probabilities through reduction in the number of disease hosts, and in the case of ITNs, reduction of the vector itself. In contrast, ACT uptake creates both positive externalities when individuals with malaria are treated, and negative externalities in the case of overtreatment that speeds up the spread of long-run parasite resistance. Moreover, ITNs, IPTp, and ACTs are experience goods (meaning individuals only ascertain their benefits upon usage), which implies that current preventive actions are linked to past preventive behaviors. Malaria prevention and eradication produce unambiguous benefits across various domains: economic conditions, educational outcomes, survival, fertility, and health. However, despite the high private returns to prevention, the adoption of antimalarial products and behaviors remains relatively low in malaria-affected areas. A variety of explanations have been proposed for low adoption rates, including financial constraints, high prices, and absence of information. While recent studies highlight that all of these factors play a role, the main barrier to adoption is probably financial constraints. This finding has implications regarding the appropriate pricing policy for these health products. In addition, there is a shortage of causally identified research on the effect of cultural and psychological barriers to the adoption of preventive behaviors. The literature which does exist is from a few randomized control trials of few individuals in very specific geographic and cultural contexts, and may not be generalizable. As a result, there are still ample opportunities for research on applying the insights of behavioral economics to malaria-preventive behavior in particular. Moreover, little research has been done on the supply side, such as whether free or heavily subsidized distribution of prevention technologies is fiscally sustainable; finding effective methods to solve logistical problems which lead to shortages and ineffective alternative treatments to fill the gap; or training sufficient healthcare workers to ensure smooth and effective delivery. Given these gaps in the literature, there are still multiple fruitful avenues for research which may have a first-order effect on reducing the prevalence of malaria in the developing world.

  • Multiwinner approval rules as apportionment methods Article dans une revue:

    During the first round of the 2012 French presidential election, participants in an in situ experiment were invited to vote according to “evaluative voting”, which involves rating the candidates using a numerical scale. Various scales were used: (0,1), (-1,0,1), (0,1,2), and (0,1,…,20). The paper studies scale calibration effects, i.e., how individual voters adapt to the scale, leading to possibly different election outcomes. The data show that scales are not linearly equivalent, even if individual ordinal preferences are not inconsistent. Scale matters, notably because of the symbolic power of negative grades, which does not affect all candidates uniformly.

  • Savage’s Theorem Under Changing Awareness Article dans une revue:

    This paper proposes a simple unified framework of choice under changing awareness, addressing both outcome awareness and (nature) state awareness, and both how fine and how exhaustive the awareness is. Six axioms characterize an (essentially unique) expected-utility rationalization of preferences, in which utilities and probabilities are revised according to three revision rules when awareness changes: (R1) utilities of unaffected outcomes are transformed affinely; (R2) probabilities of unaffected events are transformed proportionally; (R3) enough probabilities ‘objectively’ never change (they represent revealed objective risk). Savage’s Theorem is a special case of the theorem, namely the special case of fixed awareness, in which our axioms reduce to Savage’s axioms while R1 and R2 hold trivially and R3 reduces to Savage’s requirement of atomless probabilities. Rule R2 parallels Karni and Viero’s (2013) ‘reverse Bayesianism’ and Ahn and Ergin’s (2010) ‘partition-dependence’. The theorem draws mathematically on Kopylov (2007), Niiniluoto (1972) and Wakker (1981).

  • In search of unanimously preferred income distributions. Evidence from a choice experiment Pré-publication, Document de travail:

    Using a choice-experiment in the lab, we look at preferences over pairs of income distributions within small groups in a firm-like setting. Is one type of distribution capable of attracting votes unanimously? It turns out that Pareto-dominance is the most important choice criterion: in binary choices over two distributions, all subjects prefer larger inequality when it makes everyone weakly better off. This is true,no matter whether income distribution is based on merit or luck. Unanimity only breaks once subjects’ positions within the income distribution are fixed and known ex-ante. However, even then, 75% subjects prefer Pareto-dominant distributions. This suggests that efficiency motives are of primary importance, more so than the origin of inequality.

  • Math, girls and socialism Article dans une revue:

    This paper argues that the socialist episode in East Germany, which constituted a radical experiment in gender equality in the labor market and other instances, has left persistent tracks on gender norms. We focus on one of the most resilient and pervasive gender gaps in modern societies: mathematics. Using the German division as a natural experiment, we show that the underperformance of girls in math is sharply reduced in the regions of the former GDR, in contrast with those of the former FRG. We show that this East–West difference is due to girls’ attitudes, confidence and competitiveness in math, and not to other confounding factors, such as the difference in economic conditions or teaching styles across the former political border. We also provide illustrative evidence that the gender gap in math is smaller in European countries that used to be part of the Soviet bloc, as opposed to the rest of Europe. The lesson is twofold: (1) a large part of the pervasive gender gap in math is due to social stereotypes; (2) institutions can durably modify these stereotypes.

  • Coordination with communication under oath Article dans une revue:

    We focus on the design of an institutional device aimed to foster coordination through communication. We explore whether the social psychology theory of commitment, implemented via a truth-telling oath, can reduce coordination failure. Using a classic coordination game, we ask all players to sign voluntarily a truth-telling oath before playing the game with cheap talk communication. Three results emerge with commitment under oath: (1) coordination increased by nearly 50 percent; (2) senders’ messages were significantly more truthful and actions more efficient, and (3) receivers’ trust of messages increased.

  • A mixed-utility theory of vote choice regret Article dans une revue:

    The paper builds upon an original pre- and post-election survey that we conducted before and after the 2015 Canadian election. Directly after Election Day, we asked Canadians for which party they voted, and whether they regret their choice. We find that 39% of them are not perfectly happy with their decision, and 4% even say that they made a bad decision. We show that the propensity to regret can be explained by a mixed-utility theory, whereby voters attempt to maximize a mixture of instrumental and expressive utilities. Our study contributes to the literatures on voting behaviour and political economy, which usually considers that voters are either instrumental or expressive, but not both at the same time.

    Studying a sample of recently published papers in the main Economics journals, I find that these American journals mostly publish work on American data, written by members of American universities. I argue that this state of affairs is not essentially because of a language problem, but is explained by the domination of US universities on the international academic market in Economics. This domination has thus direct consequences for the topics of research, and thus for the accumulation of knowledge, in Economics.

  • Impulsivity and consideration of future consequences as moderators of the association between emotional eating and body weight status Article dans une revue:

    Background: Emotional eating (EmE) is characterized by an over consumption of food in response to negative emotions and is associated with an increased weight status. Consideration of Future Consequences (CFC) or a low level of impulsivity could influence the association between EmE and weight status. The objective was to analyze the moderating influence of CFC and impulsivity on the relationship between EmE and BMI. Methods: A total of 9974 men and 39,797 women from the NutriNet-Sante cohort study completed the revised 21-item Three-Factor Eating Questionnaire to assess their EmE, the CFC questionnaire (CFC-12) to assess their level of time perspective, and the Barratt Impulsiveness Scale (BIS-11) to assess their impulsivity. Weight and height were self-reported each year over a median follow-up of 5.3 years. The associations between EmE and repeated measures of BMI were estimated by multiple linear mixed-effects regression models stratified by gender, tertiles of the CFC, or tertiles of the BIS-11, taking into account sociodemographic and lifestyle factors. Results: Overall, EmE was positively associated with BMI. CFC and impulsivity did not moderate the effect of EmE on changes of BMI per year, but quantitatively moderated the effect of EmE on overall BMI. In women, the strength of the association between EmE and weight status increased with CFC level. Difference of BMI slopes between a low and a high level of CFC was – 0.43 kg/m(2) (95% CI: -0.55, – 0.30) (p < .0001). In addition, the strength of the association between emotional eating and weight status increased with impulsivity level. Difference of BMI slopes between a low and a high level of impulsivity was + 0.37 kg/m(2) (95% CI: 0.24, 0.51) (p < .0001). In men, only individuals with a low CFC presented a stronger association of EmE with BMI. Conclusions: Impulsivity and consideration of future consequences moderated the association between emotional eating and body weight status. This study emphasizes the importance of taking into account psychological traits in obesity prevention.

  • Preparation for old age in France: The roles of preferences and expectations Article dans une revue:

    This article assesses the roles of preferences and expectations on preparation for old age, employing unique data on French individuals aged 50+ . The data do not only contain information on the general feeling to prepare for old age and on specific preparation activities in various domains, but also on risk and time attitudes, family and social altruism, and expected disability and longevity. Half of the sample reports preparing for old age. Future orientation emerges as an important predictor of preparation. While risk attitudes and altruism also matter for preparation, their effect may be less systematic across outcomes than that of general future orientation. Individuals who expect to become disabled or to live longer are more likely to prepare for old age. Policies promoting healthy aging should include messages targeting present-oriented individuals and try to make people more future-oriented.

  • Experimental Economics. Method and Applications Ouvrages:

    Over the past two decades, experimental economics has moved from a fringe activity to become a standard tool for empirical research. With experimental economics now regarded as part of the basic tool-kit for applied economics, this book demonstrates how controlled experiments can be a useful in providing evidence relevant to economic research. Professors Jacquemet and L’Haridon take the standard model in applied econometrics as a basis to the methodology of controlled experiments. Methodological discussions are illustrated with standard experimental results. This book provides future experimental practitioners with the means to construct experiments that fit their research question, and new comers with an understanding of the strengths and weaknesses of controlled experiments. Graduate students and academic researchers working in the field of experimental economics will be able to learn how to undertake, understand and criticise empirical research based on lab experiments, and refer to specific experiments, results or designs completed with case study applications.

  • Association between time perspective and organic food consumption in a large sample of adults Article dans une revue:

    Background: Organic food intake has risen in many countries during the past decades. Even though motivations associated with such choice have been studied, psychological traits preceding these motivations have rarely been explored. Consideration of future consequences (CFC) represents the extent to which individuals consider future versus immediate consequences of their current behaviors. Consequently, a future oriented personality may be an important characteristic of organic food consumers. The objective was to analyze the association between CFC and organic food consumption in a large sample of the adult general population. Methods: In 2014, a sample of 27,634 participants from the NutriNet-Santé cohort study completed the CFC questionnaire and an Organic-Food Frequency questionnaire. For each food group (17 groups), non-organic food consumers were compared to organic food consumers across quartiles of the CFC using multiple logistic regressions. Moreover, adjusted means of proportions of organic food intakes out of total food intakes were compared between quartiles of the CFC. Analyses were adjusted for socio-demographic, lifestyle and dietary characteristics. Results: Participants with higher CFC were more likely to consume organic food (OR quartile 4 (Q4) vs. Q1 = 1.88, 95% CI: 1.62, 2.20). Overall, future oriented participants were more likely to consume 14 food groups. The strongest associations were observed for starchy refined foods (OR = 1.78, 95% CI: 1.63, 1.94), and fruits and vegetables (OR = 1.74, 95% CI: 1.58, 1.92). The contribution of organic food intake out of total food intake was 33% higher in the Q4 compared to Q1. More precisely, the contribution of organic food consumed was higher in the Q4 for 16 food groups. The highest relative differences between Q4 and Q1 were observed for starchy refined foods (22%) and non-alcoholic beverages (21%). Seafood was the only food group without a significant difference.

  • Women’s employment and the decline of home cooking: Evidence from France, 1985–2010 Article dans une revue:

    We here investigate the extent to which labour-market changes explain the decline in the time spent home cooking by married women in France between 1985 and 2010. Using time use data and Oaxaca-Blinder decompositions, we find that rising women’s employment and observed wages together account for about 60% of the fall in the time married women spent cooking. We then use a semi-parametric matching technique to construct an implicit wage rate, which better reflects the change in labour-market incentives that individuals face. The rise in women’s implicit wages explains no more than 20% of the decline in their cooking time, while the wage of their partner has no effect. Changing labour-market incentives are thus far from being the main driver of the decline in home-cooking. We also find evidence that home cooking continues to be structured by the gendered social norm of the “proper family meal”.

    A “walk up” survey conducted in the city of Caen between the two rounds of the 2017 French presidential election shows that more than one elector in six would like to have changed their first-round vote. Some voters faced a dilemma between strategic and expressive voting. The analysis of their motivation reveals that both types of regrets were present: many respondents wished that they had voted more strategically, and just as many wished that they had voted less strategically. Many participants also considered that they would rather have cast a blank vote in the first round rather than choosing a particular candidate.

  • Dynamic effects of enforcement on cooperation Article dans une revue:

    In situations where social payoffs are not aligned with private incentives, enforcement with fines can be a way to sustain cooperation. In this paper we show, by the means of a lab experiment , that past fines can have an effect on current behavior even when no longer in force. We document two mechanisms: a) past fines affect directly individuals’ future propensity to cooperate; b) when fines for non cooperation are in place in the past, individuals experience higher levels of cooperation from partners and, consistent with indirect reciprocity motives, are in turn nicer towards others once these fines have been removed. This second mechanism is empirically prevalent and, in contrast with the first, induces a snowball effect of past enforcement. Our results can inform the design of costly enforcement policies.

Data on program, design, and economic characteristics were extracted using a predefined extraction form. The quality of the economic evaluations was appraised using the adjusted Consensus Health Economic Criteria List. Results: A total of 426 articles were identified and thirty-seven studies were selected. Eleven studies dealt with musculoskeletal and rheumatologic disorders, ten with cardiovascular diseases, six with neurological disorders, three with mental illnesses, three with cancers, and four with diabetes, respiratory diseases, or pelvic organ prolapse. In total, 60 percent of exercise programs were dominant or cost-effective. For musculoskeletal and rheumatologic disorders, 72 percent of programs were dominant or cost-effective while this was the case for 57 percent of programs for cardiovascular diseases using a nonsurgical comparator. Conclusions: There is clear evidence in favor of exercise-based programs for the treatment of musculoskeletal and rheumatologic disorders and, to a lesser extent, for the treatment of cardiovascular diseases. More research is needed to evaluate the cost-effectiveness of physical activity in the treatment of neurological disorders, mental illnesses, cancers, respiratory diseases, and diabetes/obesity.

  • Truth-telling under Oath Communication dans un congrès:

    Oath taking for senior executives has been promoted as a means to enhance honesty within and toward organizations. Herein we explore whether people who voluntarily sign a solemn truth-telling oath are more committed to sincere behavior when offered the chance to lie. We design an experiment to test how the oath affects truth telling in two contexts: a neutral context replicating the typical experiment in the literature, and a “loaded” context in which we remind subjects that “a lie is a lie.” We consider four payoff configurations, with differential monetary incentives to lie, implemented as within-subjects treatment variables. The results are reinforced by robustness investigations in which each subject made only one lying decision. Our results show that the oath reduces lying, especially in the loaded environment—falsehoods are reduced by 50%. The oath, however, has a weaker effect on lying in the neutral environment. The oath did affect decision times in all instances: the average person takes significantly more time deciding whether to lie under oath.

  • Votes for Women: Electoral Systems and Support for Female Candidates Article dans une revue:

    It is a well-established finding that proportional representation (PR) electoral systems are associated with greater legislative representation for women than single member systems. However, the degree to which different types of PR rules affect voting for female candidates has not been fully explored. The existing literature is also hampered by a reliance on cross-national data in which individual vote preferences and electoral system features are endogenous. In this study, we draw upon an experiment conducted during the 2014 European Parliament (EP) elections to isolate the effects of different PR electoral systems. Participants in the experiment were given the opportunity to vote for real EP candidates in three different electoral systems: closed list, open list, and open list with panachage and cumulation. Because voter preferences can be held constant across the three different votes, we can evaluate the extent to which female candidates were more or less advantaged by the electoral system itself. We find that voters, regardless of their gender, support female candidates, and that this support is stronger under open electoral rules.

  • Unfairness at Work: Well-Being and Quits Pré-publication, Document de travail:

    We here consider the effect of unfair income on both subjective well-being and objective future job quitting. In five waves of German Socio-Economic Panel data, those who perceive their labour income to be unfair have significantly lower subjective well-being, both in terms of cognitive evaluations (life and job satisfaction) and affect (the frequency of feeling happy, sad, angry and worried). Perceived unfairness also translates into objective labour-market behaviour, with current unfair income predicting future job quits.

  • Modelling Heterogeneity in the Resilience to Major Socioeconomic Life Events Pré-publication, Document de travail:

    Using a novel, dynamic finite mixture model applied to 12 years of nationally representative panel data, we explore individual heterogeneity in the total psychological response (our measure of resilience) to ten major adverse life events, including serious illness, redundancy and crime victimisation. Importantly, this model takes into account that individuals are not randomly selected into adverse events, that some events are anticipated in advance of their occurrence, and that the immediate psychological response and the speed of adaptation may differ across individuals. Additionally, we generate a ‘standardised event’ in order to document the distribution of general resilience in the population. We find considerable heterogeneity in the response to adverse events, with the total psychological loss of people with low resilience being several times larger than the average loss. We also find that resilience is strongly correlated with clinical measures of mental health, but only weakly correlated with cognitive and non-cognitive traits. Finally, we find that resilience in adulthood to some extent is predictable by childhood socioeconomic circumstances; the strongest predictor we identify is good childhood health.

  • Association between Impulsivity and Weight Status in a General Population Article dans une revue:

    The objective of this study is to examine the association between impulsivity and weight status in a large sample of the adult general population in France, and the influence of gender on this relationship. A total of 11,929 men and 39,114 women participating in the NutriNet-Santé cohort were selected in this cross-sectional analysis. The Barratt Impulsiveness Scale (BIS-11) was used to assess impulsivity. Weight and height were self-reported. The association between impulsivity and BMI was estimated using logistic regressions adjusted for socio-demographic and lifestyle factors. Individuals with high impulsivity levels (BIS-11 total score >71) were more likely to be obese (Odds Ratio (OR) = 1.80, 95% Confidence Interval (CI): 1.39, 2.33 in men; OR = 1.30, 95% CI: 1.15, 1.48 in women) compared to individuals in the average range of impulsivity. The strongest associations between impulsivity and obesity were observed in men, where highly impulsive participants were more likely to be class III obese (BMI > 40 kg/m²) (OR = 3.57, 95% CI: 1.86, 6.85). This large sample analysis supports the existence of a relationship between impulsivity and weight status and the importance of psychological factors in the prevention of obesity.

  • Probabilistic opinion pooling generalized. Part two: The premise-based approach Article dans une revue:

    How can several individuals’ probability functions on a given-algebra of events be aggregated into a collective probability function? Classic approaches to this problem usually require ‘event-wise independence’: the collective probability for each event should depend only on the individuals’ probabilities for that event. In practice, however, some events may be ‘basic’ and others ‘derivative’, so that it makes sense first to aggregate the probabilities for the former and then to let these constrain the probabilities for the latter. We formalize this idea by introducing a ‘premise-based’ approach to probabilistic opinion pooling, and show that, under a variety of assumptions, it leads to linear or neutral opinion pooling on the ‘premises’.

  • Globalisation and national trends in nutrition and health -a grouped fixed-effects approach to inter-country heterogeneity Pré-publication, Document de travail:

    Using a panel dataset of 70 countries spanning 42 years (1970-2011), we investigate the distinct effects of social globalisation and trade openness on national trends in markers of diet quality (supplies of animal proteins, free fats and sugar, average body mass index – BMI – and diabetes prevalence). Our key methodological contribution is the application of a grouped fixed-effects (GFE) estimator, which extends linear fixed-effects models. The GFE estimator partitions our sample into distinct groups of countries in order to control for time-varying unobserved heterogeneity that follows a group-specific pattern. We find that increasing social globalisation has a significant impact on the supplies of animal protein and sugar available for human consumption, as well as on mean BMI. Specific components of social globalisation such as information flows (via television and the Internet) drive these results. Trade openness has no effect on dietary outcomes or health. These findings suggest that the social and cultural aspects of globalisation should receive greater attention in research on the nutrition transition.

  • Fair management of social risk Article dans une revue:

    We provide a general method for extending social preferences defined for riskless economic environments to the context of risk and uncertainty. We apply the method to the problems of managing unemployment allowances (in the context of macroeconomic fluctuations) and catastrophic risks (in the context of climate change). The method guarantees ex post fairness and pays attention to individuals’ risk attitudes, while ensuring rationality properties for social preferences, revisiting basic ideas from Harsanyi’s celebrated aggregation theorem (Harsanyi, 1955). The social preferences that we obtain do not always take the form of an expected utility criterion, but they always satisfy statewise dominance. When we require social preferences to be expected utilities, we obtain a variant of Harsanyi’s result under a weak version of the Pareto principle, and a maximin criterion under a stronger Pareto requirement, whenever the ex post social ordering does not depend on people’s risk attitudes. We also show how non-expected utility individual preferences can be accommodated in the approach.

  • Household Labour Supply and the Marriage Market in the UK, 1991-2008 Article dans une revue:

    We document changes in labour supply, wage and education by gender and marital status using the British Household Panel Survey, 1991-2008, and seek to disentangle the main channels behind these changes. To this end, we use a version of Goussé, Jacquemet, and Robin (2016)’s search-matching model of the marriage market with labour supply, which does not use information on home production time inputs. We derive conditions under which the model is identified. We estimate different parameters for each year. This allows us to quantify how much of the changes in labour supply, wage and education by gender and marital status depends on changes in the preferences for leisure of men and women and how much depends on changes in homophily.

  • Paludisme et anémie des enfants en Afrique subsaharienne : effet de la distribution de moustiquaires Article dans une revue:

    Cet article évalue l’effet de différentes politiques de lutte contre le paludisme, et en particulier de la politique dite de « mise à l’échelle » de la distribution de moustiquaires, sur la probabilité d’anémie des enfants en Afrique subsaharienne. Les données combinent des informations individuelles sur plus de 150 000 enfants et leur famille, et des informations régionales sur l’intensité du paludisme avant le lancement des campagnes, pour seize pays, entre 2000 et 2014. La méthode utilisée est celle des doubles différences, qui teste si les politiques ont entraîné une baisse plus forte de l’anémie dans les régions où l’intensité du paludisme était plus élevée. Les résultats indiquent que la mise à l’échelle a un effet faible ou négligeable sur la probabilité d’anémie modérée ou sévère, tandis que les autres politiques n’ont pas d’effet significatif.

  • Happiness, income and poverty Article dans une revue:

    There is considerable evidence from a variety of sources to suggest that well-being is a function of relative income. These findings have been used to explain the Easterlin Paradox, whereby a rise in income for all does not lead to a rise in average happiness in a country (even though the cross section relationship between income and happiness is positive). This relativity of utility has led to calls for policy to focus away from GDP. I here first discuss some of the evidence that well-being is indeed relative in income, but then consider two relatively little-analysed issues to suggest that there may continue to be a role for GDP per capita in happiness-based policy: the inequality of subjective well-being, and the specific case of those in income poverty.

    Le 1er Juin 2017 JF Laslier Résumé Le « Jugement majoritaire » est un mode de scrutin par évaluation qui choisit le candidat ayant la meilleure évaluation médiane. L’article est consacré à la question : Que fait-on quand on choisit suivant la meilleure médiane ? Ce principe revient à déterminer quelle demi-population négliger pour satisfaire, dans le sens d’un compromis rawlsien, l’autre moitié. Il apparaît en contradiction avec la définition de la démocratie comme participation de tous, et non pas de la moitié de la population plus un. De plus, satisfaire au mieux la demi-population la plus facile à satisfaire n’est pas ce que produisent les règles de choix « majoritaires », c’est à dire respectant le principe de Condorcet ; ces règles tendent au contraire à promouvoir les solutions globalement consensuelles, tout particulièrement dans les environnements politiques. Ceci explique les résultats surprenants que tend à produire ce système.

  • Reaching consensus through approval bargaining Article dans une revue:

    In the Approval Bargaining game, two players bargain over a finite set of alternatives. To this end, each one simultaneously submits a utility function u jointly with a real number α; by doing so she approves the lotteries whose expected utility according to u is at least α. The lottery to be implemented is randomly selected among the most approved ones. We first prove that there is an equilibrium where players truthfully reveal their utility function. We also show that, in any equilibrium, the equilibrium outcome is approved by both players. Finally, every equilibrium is sincere and Pareto efficient as long as both players are partially honest.

  • The Long-Lasting Effects of Family and Childhood on Adult Wellbeing: Evidence from British Cohort Data Pré-publication, Document de travail:

    To what extent do childhood experiences continue to affect adult wellbeing over the life course? Previous work on this link has been carried out either at one particular adult age or for some average of adulthood. We here use two British birth-cohort datasets (the 1958 NCDS and the 1970 BCS) to map out the time profile of the effect of childhood on adult outcomes, including life satisfaction. We find that the effect of many aspects of childhood do not fade away over time, but are rather remarkably stable. In both birth cohorts child non-cognitive skills are the strongest predictors of adult life satisfaction at all ages. Of these, emotional health is the strongest. Childhood cognitive performance is more important than good conduct in explaining adult life satisfaction in the earlier cohort, whereas this ranking is inverted in the more recent BCS.

  • Early-life correlates of later-life well-being: Evidence from the Wisconsin Longitudinal Study Pré-publication, Document de travail:

    We use data from the Wisconsin Longitudinal Study (WLS) to consider the distal and proximal correlates of happiness and eudaimonia in later life. Even after controlling for proximal covariates, outcomes at age 18 (IQ score, parental income and parental education) remain good predictors of well-being over 50 years later. In terms of the proximal covariates, mental health and social participation are the strongest predictors of well-being. Although some factors are important in explaining both happiness and eudaimonia, there are notable differences between the two measures: well-being policy will thus depend to an extent on which measure is preferred.

  • Referenda Under Oath Article dans une revue:

    Herein we explore whether a solemn oath can eliminate hypothetical bias in a voting referenda, a popular elicitation mechanism promoted in non-market valuation exercises for its incentive compatibility properties. First, we reject the null hypothesis that a hypothetical bias does not exist. Second, we observe that people who sign an oath are significantly less likely to vote for the public good in a hypothetical referenda. We complement this evidence with a self-reported measure of honesty which confirms that the oath increases truthfulness in answers. This result opens interesting avenues for improving the elicitation of preferences in the lab and beyond.

  • Développements récents de l’économie comportementale et expérimentale : Introduction Article dans une revue:

    La méthode expérimentale a profondément influencé les développements récents de la sciencé economique. L’utilisation d’expériences, et son caractère quasi-systématiquè a partir des années 1990, a permis de développer uné evaluation empiriquè a la fois des hypothèses sur lesquelles repose l’analyse théorique (par exemple : combien d’acteurs sont nécessaires nécessairesà donner du sensàsensà la notion d’atomicité, qui se traduit empiriquement par des agents qui se comportent comme preneurs de prix ? Quel horizon temporel réplique la notion de jeu infiniment répété, dont la conséquence essentielle est de rendre les décisions contemporaines indépendantes desévénementsdesévénements futurs ?), mais aussi des prédictions de modèles spécifiques (l’´ equilibre offre-demande sur un marché, la formation des prix et l’allocation d’un bien dans le cadre d’une enchère). L’´ economie expérimentale a ainsi mis enévidenceenévidence la pertinence et la validité de certaines approches théoriques, malgré des hypothèses souvent très fortes sur les comportements individuels et sociaux, mais aussi leurs limites dans un certain nombre d’autres situations. Les deux lauréats du » Prix Nobel d’´ economie » (ou Prix de la Banque deSù ede en mémoire d’Alfred Nobel) dont la distinction fut explicitement motivée par leurs contributions expérimentales, illustrent parfaitement cette tension : les travaux de Vernon Smith montrent que, pour certaines institutions d’´ echanges bien définies, les marchés fonctionnent demanì ere très cohérente avec la théorie de la concurrence pure et parfaite, alors même que la plupart des hypothèses sous-jacentesàjacentesà cette théorie sont, au mieux, modérément satisfaites. A contrario, Daniel Kahneman, co-lauréat la même année, reçoit le prix pour la mise enévidenceenévidence de biais cognitifs et d’une tendance des individusàindividusà s’´ ecarter des canons de la rationalité mis en avant dans les modèles microéconomiques. Sur la base de cette tension et en lien trèstrèsétroit avec l’´ economie expérimentale, s’est développé un nouveau champ de recherche, l’´ economie comportementale, dont l’objectif est d’enrichir et amender l’approche théorique des décisions individuelles et sociales sur la base de régularités psy-chologiques. Il s’agit d’incorporer aux modèles canoniques les motivations non-monétaires et les inclinations moinségo¨ıstesmoinségo¨moinségo¨ıstes des individus, ou les raccourcis cognitifs sur lesquels ils peuvent se fonder, pour prendre leurs décisions ou encore d’´ eventuelles incohérences de com-portement.

    We here consider the cognitive and non-cognitive consequences on young adults of growing up with a mother who reported experiencing major financial problems. We use data from the Avon Longitudinal Study of Parents and Children to show that early childhood financial problems are associated with worse adolescent cognitive and non-cognitive outcomes, controlling for both income and a set of standard variables. The estimated effect of financial problems is almost always larger in size than that of income. Around one quarter to one half of the effect of financial problems on the non-cognitive outcomes seems to transit through mother’s mental health.

  • When experienced and decision utility concur: The case of income comparisons Article dans une revue:

    While there is now something of a consensus in the economics of happiness literature that income comparisons to others help determine subjective well-being, debate continues over the relative importance of own and reference-group income, in particular in research on the Easterlin paradox. The variety of results in this domain have produced some scepticism regarding happiness analysis, and in particular with respect to the measurement of reference-group income. We here use data from an original Internet survey in Japan to compare the relative-income results from happiness regressions to those from hypothetical-choice experiments. This kind of validation of experienced utility via direct comparison with decision utility remains rare in this literature.

  • What matters and how it matters: a choice-theoretic representation of moral theories Article dans une revue:

    This essay presents a new “reason-based” approach to the formal representation of moral theories, drawing on recent decision-theoretic work. It shows that any moral theory within a very large class can be represented in terms of two parameters: (i) a specification of which properties of the objects of moral choice matter in any given context, and (ii) a specification of how these properties matter. Reason-based representations provide a very general taxonomy of moral theories, as differences among theories can be attributed to differences in their two key parameters. We can thus formalize several distinctions, such as between consequentialist and nonconsequentialist theories, between universalist and relativist theories, between agent-neutral and agent-relative theories, between monistic and pluralistic theories, between atomistic and holistic theories, and between theories with a teleological structure and those without. Reason-based representations also shed light on an important but underappreciated phenomenon: the “underdetermination of moral theory by deontic content.”

  • Preparation for old age in France: The roles of preferences and expectations Pré-publication, Document de travail:

    This article assesses the roles of preferences and expectations on preparation for old age, employing unique data on French individuals aged 50+. The data do not only contain information on the general feeling to prepare for old age and on specific preparation activities in various domains, but also on risk and time attitudes, family and social altruism, and expected disability and longevity. Half of the sample reports preparing for old age. Future orientation emerges as an important predictor of preparation. While risk attitudes and altruism also matter for preparation, their effect may be less systematic across outcomes than that of general future orientation. Individuals who expect to become disabled or to live longer are more likely to prepare for old age. Policies promoting healthy aging should include messages targeting present-oriented individuals and try to make people more future-oriented.

  • Democracy for Polarized Committees: The Tale of Blotto’s Lieutenants Article dans une revue:

    In polarized committees, majority voting disenfranchises the minority. Allowing voters to spend freely a fixed budget of votes over multiple issues restores some minority power. However, it also creates a complex strategic scenario: a hide-and-seek game between majority and minority voters that corresponds to a decentralized version of the Colonel Blotto game. We offer theoretical results and bring the game to the laboratory. The minority wins as frequently as theory predicts, despite subjects deviating from equilibrium strategies. Because subjects understand the logic of the game — minority voters must concentrate votes unpredictably — the exact choices are of secondary importance, a result that vouches for the robustness of the voting rule to strategic mistakes.

  • Premature deaths, accidental bequests and fairness Pré-publication, Document de travail:

    While little agreement exists regarding the taxation of bequests in general, there is a widely held view that accidental bequests should be subject to a confi…scatory tax. We propose to reexamine the optimal taxation of accidental bequests in an economy where individuals care about what they leave to their offspring in case of premature death. We show that, whereas the conventional 100 % tax view holds under the standard utilitarian social welfare criterion, it does not hold under the ex post egalitarian criterion, which assigns a strong weight to the welfare of unlucky short-lived individuals. From an egalitarian perspective, it is optimal not to tax, but to subsidize accidental bequests. We examine the robustness of those results in a dynamic OLG model of wealth accumulation, and show that, whereas the sign of the optimal tax on accidental bequests depends on the form of the joy of giving motive, it remains true that the 100 % tax view does not hold under the ex post egalitarian criterion.

  • Pourquoi la demande d’actions baisse-t-elle pendant la crise ? Le cas français Article dans une revue:

    La crise économique a affecté les épargnants français, moins enclins à prendre des risques dans leurs comportements financiers. Comment expliquer ces changements ? La théorie standard fait dépendre les investissements des épargnants de trois déterminants fondamentaux : les ressources présentes ; les anticipations de rendement et de risque des actifs, mais aussi celles sur les revenus du travail ; et enfin les préférences de l’agent, notamment vis‑à‑vis du risque. Nous utilisons les données françaises du panel Pater réalisé en 2007 puis en 2009, 2011 et 2014. Nous montrons que la révision à la baisse des anticipations concernant les rendements espérés des actions et les chocs sur les ressources courantes contribue à expliquer que les placements des Français sont de moins en moins investis en actifs risqués. En revanche, les préférences à l’égard du risque sont restées stables. Cependant le retour à l’optimisme des épargnants en 2014 ne s’est pas traduit dans les faits puisque le nombre d’actionnaires a continué de diminuer. Une nouvelle énigme ?

  • Why does household demand for shares decline during the crisis? The French case Article dans une revue:

    The economic crisis has impacted French savers, now less willing to take risks in their financial decisions. What is the explanation behind these changes? According to “standard” theory, savers’ investments rest on three fundamental determinants: present resources; expected risk and returns on assets, as well as expectations on earned income; and lastly, individual preferences, especially risk preferences. We use French data from the Pater panel, a survey collected in 2007 and again in 2009, 2011 and 2014. We show that it is the downward adjustment in the expected return from shares and negative impacts on current resources that help explain why the French are investing less and less in risky assets. Risk preferences, however, have remained stable. In contrast, the resurgence in optimism shown by savers in 2014 did not play out in reality, as the number of shareholders has continued to decrease. A new puzzle to be solved?

  • The effect of ambient temperature shocks during conception and early pregnancy on later life outcomes Article dans une revue:

    A large body of research has recently shown that early life or in utero shocks, especially climatic shocks, may affect long-run human capital outcomes. Most of these effects are assumed to be biological – including poor nutrition during critical windows of fetal development, or through increased maternal stress. However, in addition to these biological effects, climatic conditions at the time of conception may also cause changes in parental behavior, not only affecting the mix of parents who conceive, but also the characteristics of the children once born. This paper explores whether increases in ambient temperature at the time of conception, while in utero, or after birth affect educational and health outcomes as adults. Using Census and Demographic and Health Survey data from sub-Saharan Africa, we show that individuals conceived during high temperatures have higher educational attainment and literacy. In addition, we find evidence of temperature effects at other times in utero, especially during the first trimester. We then explore the biological and behavioral mechanisms through which this effect may occur, including heat-induced changes in sexual behavior, differences in parental characteristics, and intensified fetal selection. We conclude that fetal selection is the most likely mechanism driving our result.

  • Marriage, Labor Supply, and Home Production Article dans une revue:

    We develop a search model of marriage where men and women draw utility from private consumption and leisure, and from a non-market good that is produced in the home using time resources. We condition individual decisions on wages, education, and an index of family attitudes. A match-specific, stochastic bliss shock induces variation in matching given wages, education, and family values, and triggers renegotiation and divorce. Using BHPS (1991–2008) data, we take as given changes in wages, education, and family values by gender, and study their impact on marriage decisions and intra-household resource allocation. The model allows to evaluate how much of the observed gender differences in labor supply results from wages, education, and family attitudes. We find that family attitudes are a strong determinant of comparative advantages in home production of men and women, whereas education complementarities induce assortative mating through preferences.

  • Drug price regulation Chapitre d’ouvrage:

    Drug prices are regulated in a legal framework that organizes the negotiation between pharmaceutical firms and a third-party payer responsible for healthcare reimbursement. This regulation aims at compensating for market failures associated with drug specificities. Explicit economic reasoning through the socalled health technology assessment framework is increasingly embedded in the institutional and administrative process of the evaluation procedure leading to market access, pricing and reimbursement for new drugs.

  • Reinforcement learning from comparisons: Three alternatives are enough, two are not Article dans une revue:

    This paper deals with two generalizations of the Polya urn model where, instead of sampling one ball from the urn at each time, we sample two or three balls. The processes are defined on the basis of the problem of finding the best alternative using pairwise comparisons which are not necessarily transitive: they can be thought of as evolutionary processes that tend to reinforce currently efficient alternatives. The two processes exhibit different behaviors: with three balls sampled, we prove almost sure convergence towards the unique optimal solution of the comparisons problem while, in some cases, the process with two balls sampled has almost surely no limit. This is an example of a natural reinforcement model with no exchangeability whose asymptotic behavior can be precisely characterized.

  • Ce que le vote par approbation révèle des préférences des électeurs français Article dans une revue:

    Cet article vise à déterminer une répartition, le long d’un axe politique, des candidats à l’élection présidentielle de 2012 qui soit fondée sur les opinions exprimées par les électeurs à travers une expérimentation de vote par approbation, plutôt que sur un positionnement a priori. L’axe endogène représentatif du paysage politique obtenu s’avère correspondre à un axe gauche-droite classique. Cependant, des analyses plus précises du comportement des électeurs remettent en cause l’hypothèse d’unimodalité des préférences politiques qui est généralement associée à cette structure. En particulier, l’attitude qui consiste à approuver simultanément des candidats situés des deux côtés de l’échiquier politique mais sans soutenir les candidats intermédiaires sur l’axe est largement répandue, et nettement plus fréquente chez les hommes que chez les femmes.

  • Probabilistic opinion pooling generalized. Part one: General agendas Article dans une revue:

    How can several individuals’ probability assignments to some events be aggregated into a collective probability assignment? Classic results on this problem assume that the set of relevant events – the agenda – is a-algebra and is thus closed under disjunction (union) and conjunction (intersection). We drop this demanding assumption and explore probabilistic opinion pooling on general agendas. One might be interested in the probability of rain and that of an interest-rate increase, but not in the probability of rain or an interest-rate increase. We characterize linear pooling and neutral pooling for general agendas, with classic results as special cases for agendas that are algebras. As an illustrative application, we also consider probabilistic preference aggregation. Finally, we unify our results with existing results on binary judgment aggregation and Arrovian preference aggregation. We show that the same kinds of axioms (independence and consensus preservation) have radically different implications for different aggregation problems: linearity for probability aggregation and dictatorship for binary judgment or preference aggregation.

  • Paludisme et anémie des enfants en Afrique subsaharienne : Effet de la distribution de moustiquaires Pré-publication, Document de travail:

    Cet article évalue l’effet de différentes politiques de lutte contre le paludisme, et en particulier de la politique dite de « mise à l’échelle » de la distribution de moustiquaires, sur la probabilité d’anémie des enfants en Afrique subsaharienne. Les données combinent des informations individuelles sur plus de 150000 enfants et leur famille, et des informations régionales sur l’intensité du paludisme avant le lancement des campagnes, pour 16 pays, entre 2000 et 2014. La méthode utilisée est celle des différences-en-différences, qui teste si les politiques ont entraîné une baisse plus forte de l’anémie dans les régions où l’intensité du paludisme était plus élevée. Les résultats indiquent que la mise à l’échelle a un effet faible ou négligeable sur la probabilité d’anémie modérée ou sévère, tandis que les autres politiques n’ont pas d’effet significatif.

  • Judgment aggregation and agenda manipulation Article dans une revue:

    When individual judgments (‘yes’ or ‘no’) on some propositions are aggregated into collective judgments, outcomes may be sensitive to the choice of propositions under consideration (the agenda). Such agenda-sensitivity opens the door to manipulation by agenda setters. I define three types of agenda-insensitivity (‘basic’, ‘full’, and ‘focal’) and for each type axiomatically characterize the aggregation procedures satisfying it. Two axioms turn out to be central for agenda-insensitivity: the familiar independence axiom, requiring propositionwise aggregation, and the axiom of implicit consensus preservation, requiring the respect of any (possibly implicit) consensus. As the paper’s second contribution, I prove a new impossibility theorem whereby these two axioms imply dictatorial aggregation for almost all agendas.

  • Fair retirement under risky lifetime Article dans une revue:

    A premature death unexpectedly brings a life and a career to their end, leading to substantial welfare losses. We study the retirement decision in an economy with risky lifetime and compare the laissez-faire with egalitarian social optima. We consider two social objectives: (1) the maximin on expected lifetime welfare, allowing for a compensation for unequal life expectancies, and (2) the maximin on realized lifetime welfare, allowing for a compensation for unequal lifetimes. The latter optimum involves, in general, decreasing lifetime consumption profiles as well as raising the retirement age. This result is robust to the introduction of unequal life expectancies and unequal productivities.

Tout d’abord, nous décrivons les expérimentations menées en laboratoire autour de trois aspects principaux : résultats agrégés selon le mode de scrutin, vote stratégique, paradoxe du vote. Nous abordons ensuite les expérimentations In Situ, typiques de l’étude expérimentale du vote, consistant à tester en marge d’élections officielles d’envergure des méthodes de vote alternatives. Nous étudions le protocole expérimental, deux enseignements généraux –l’accueil et les réactions des électeurs– ainsi que deux enseignements spécifiques –la comparaison des résultats agrégés et la description de l’offre politique telle que perçue par les électeurs.

L’article démontre, à partir de quelques exemples, l’apport de ces attitudes intellectuelles à la science politique.

  • Parents’ education and child body weight in France: The trajectory of the gradient in the early years Article dans une revue:

    This paper explores the relationship between parental education and offspring body weight in France. Using two large datasets spanning the 1991–2010 period, we examine the existence of inequalities in maternal and paternal education and reported child body weight measures, as well as their evolution across childhood. Our empirical specification is flexible and allows this evolution to be non-monotonic. Significant inequalities are observed for both parents’ education – maternal (respectively paternal) high education is associated with a 7.20 (resp. 7.10) percentage points decrease in the probability that the child is reported to be overweight or obese, on average for children of all ages. The gradient with respect to parents’ education follows an inverted U-shape across childhood, meaning that the association between parental education and child body weight widens from birth to age 8, and narrows afterward. Specifically, maternal high education is correlated with a 5.30 percentage points decrease in the probability that the child is reported to be overweight or obese at age 2, but a 9.62 percentage points decrease at age 8, and a 1.25 percentage point decrease at age 17. The figures for paternal high education are respectively 5.87, 9.11, and 4.52. This pattern seems robust, since it is found in the two datasets, when alternative variables for parental education and reported child body weight are employed, and when controls for potential confounding factors are included. The findings for the trajectory of the income gradient corroborate those of the education gradient. The results may be explained by an equalization in actual body weight across socioeconomic groups during youth, or by changes in reporting styles of height and weight.

  • Individual Well-Being and the Allocation of Time Before and After the Boston Marathon Terrorist Bombing Pré-publication, Document de travail:

    There is a small literature on the economic costs of terrorism. We consider the effects of the Boston marathon bombing on Americans’ well-being and time allocation. We exploit data from the American Time Use Survey and Well-Being Module in the days around the terrorist attack to implement a regression-discontinuity design. The bombing led to a significant and large drop of about 1.5 points in well-being, on a scale of one to six, for residents of the States close to Boston. The happiness of American women also dropped significantly, by almost a point, regardless of the State of residence. Labor supply and other time use were not significantly affected. We find no well-being effect of the Sandy Hook shootings, suggesting that terrorism is different in nature from other violent deaths.

  • Strategic Voting in Multi-Winner Elections with Approval Balloting: A Theory for Large Electorates Pré-publication, Document de travail:

    We propose a theory of strategic voting in multi-winner elections with approval balloting: A fixed number M of candidates are to be elected; each voter votes for as many candidates as she wants; the M candidates with the most votes are elected. We assume that voter preferences are separable and that there exists a tiny probability that any vote might be misrecorded. Best responses involve voting by pairwise comparisons. Two candidates play a critical role: the weakest expected winner and the strongest expected loser. Expected winners are approved if and only if they are preferred to the strongest expected loser and expected losers are approved if and only if they are preferred to the weakest expected winner. At equilibrium, if any, a candidate is elected if and only if he is approved by at least half of the voters. With single-peaked preferences, an equilibrium always exists, in which the first M candidates according to the majority tournament relation are elected. The theory is tested on individual data from the 2011 Regional Government election in Zurich.

  • Opportunist politicians and the evolution of electoral competition Article dans une revue:

    This paper studies a uni-dimensional model of electoral competition between two parties with two types of politicians. ‘Opportunist’ ones care only about the spoils of the office, and ‘militant’ ones have ideological preferences on the policy space. Opportunist politicians review their affiliations and may switch parties, seeking better election prospects. In this framework, we compare a winner-take-all system, where all the spoils of office go to the winner, to a proportional system, where the spoils of office are split among the two parties in proportion to their vote shares. We study the existence of short term political equilibria and the dynamics and stability of policies and of party membership decisions. In the long run, it is possible that proportional systems see opportunist politicians spread over all parties, but this situation is unstable in winner-take-all systems.

  • Économie expérimentale : comportements individuels, stratégiques et sociaux – Introduction Article dans une revue:

    Les vingt-cinq dernières années ont vu se populariser un renouveau des méthodes empiriques dans de nombreux domaines de l’analyse économique. Parmi celles-ci une place de plus en plus importante a été accordée à l’emploi de méthodes expérimentales, notamment comme outil empirique privilégié d’étude des nouvelles perspectives offertes par l’économie comportementale. L’élargissement des méthodes empiriques qui a suivi ce mouvement, l’accumulation de nombre de résultats significatifs a conduit l’Actualité Economique à proposer un panorama de cette littérature, non seulement pour en présenter les prémisses et en tirer un bilan intermédiaire mais également pour en présenter les perspectives. Au sens strict, les méthodes d’économie expérimentale emploient les principes de la méthode expérimentale, inspirée des sciences naturelles, pour évaluer les prédictions des modèles économiques en se concentrant plus particulièrement sur les comportements individuels. Les piliers sur lesquels s’appuie cette méthode sont traditionnellement au nombre de trois. Le premier pilier est constitué par le contrôle de l’environnement dans lequel se font les choix individuels. Dans une expérience de laboratoire, le chercheur essayer de contrôler le plus possible le contexte dans lequel les agents économiques prennent leurs décisions, afin d’isoler l’effet d’un traitement particulier. Typiquement, la méthode expérimentale permet de spécifier de manière fine et précise les institutions d’échanges et la forme des interactions sociales, les modes de présentation des choix et les échelles de réponse afin de contrôler au mieux l’environnement de choix. Le deuxième pilier est le contrôle de l’assignation aléatoire des participants dans différents traitements. Ce deuxième pilier est fondamental pour l’identification des effets de traitements et l’évaluation empirique sous-jacente qui en est espérée. Le troisième pilier, le plus contesté, repose sur la présence d’incitations monétaires assurant que les choix effectués en laboratoire sont associés à de réelles conséquences économiques.

  • How Do Households Allocate Their Assets? Stylized Facts from the Eurosystem Household Finance and Consumption Survey Article dans une revue:

    Using the first wave of the Eurosystem Household Finance and Consumption Survey (HFCS), a large micro-level data set on households’ balance sheets in fifteen euro-area countries, this paper explores how households allocate their assets. We derive stylized facts on asset participation as well as the portfolio shares of asset holdings and investigate the systematic relationships between household characteristics and asset holding patterns. Real assets make up the bulk of total assets. Whereas ownership of the main residence varies strongly between countries, the value of the main residence tends to be the major asset for homeowners and represents a signif- icant part of total assets in all countries. While almost all households hold safe financial assets, a low share of households holds risky assets. The ownership rates of all asset categories generally increase with wealth (and income). The significance of inheritances for homeownership and holding of other real estate is remarkable. We tentatively link differences in asset holding patterns across countries to differences in institutions.

    Do couples share the same values? The social sciences have mainly concentrated on comparing the socioeconomic characteristics of spouses, but rarely consider their attitudes to risk and time. In this paper, we use conventional measurements and an original method of scoring. We find that spouses are very similar in their savings preferences, even when we control for the individual characteristics. Our results suggest that most of this relationship comes from marital sorting. These conclusions are decisive in explaining the decision process within households and its implications for wealth inequalities between households since homogamy causes a divide in the population.

  • Adaptation to Poverty in Long-Run Panel Data Article dans une revue:

    We consider the link between poverty and subjective wellbeing and focus in particular on potential adaptation to poverty. We use panel data on almost 54,000 individuals living in Germany from 1985 to 2012 to show, first, that life satisfaction falls with both the incidence and intensity of contemporaneous poverty. We then reveal that there is little evidence of adaptation within a poverty spell: poverty starts bad and stays bad in terms of subjective well-being. We cannot identify any cause of poverty entry that explains the overall lack of poverty adaptation.

    There is mixed evidence in the existing literature on whether children are associated with greater subjective well-being, with the correlation depending on which countries and populations are considered. We here provide a systematic analysis of this question based on three different datasets: two cross-national and one national panel. We show that the association between children and subjective well-being is positive only in developed countries, and for those who become parents after the age of 30 and who have higher income. We also provide evidence of a positive selection into parenthood, whereby happier individuals are more likely to have children.

  • Economic Growth Evens Out Happiness: Evidence from Six Surveys Article dans une revue:

    In spite of the great U-turn that saw income inequality rise in Western countries in the 1980s, happiness inequality has fallen in countries that have experienced income growth (but not in those that did not). Modern growth has reduced the share of both the “very unhappy” and the “perfectly happy.” Lower happiness inequality is found both between and within countries, and between and within individuals. Our cross-country regression results suggest that the extension of various public goods helps to explain this greater happiness homogeneity. This new stylized fact arguably comes as a bonus to the Easterlin paradox, offering a somewhat brighter perspective for developing countries.

  • The Effect of Introducing a Minimum Price on the Distribution of Alcohol Purchase: A Counterfactual Analysis Article dans une revue:

    We use counterfactual analysis techniques to evaluate the impact of a $2 minimum unit price (MUP) on the distribution of Australian (Victorian) household off-trade alcohol purchases. Our estimates suggest that a $2 MUP significantly reduces the purchases of at-risk households by up to −0.92 [90% CI: −1.55, −0.28] standard drinks at the highest quantiles and has substantially less effect on households purchasing at light and moderate levels. A $2 MUP may reduce the proportions of male and female shoppers purchasing at the public health threshold of more than two standard drinks per household member per day by −3.03 [90% CI: −4.83, −1.22] percentage points (relative variation: −17%); and −1.85 [90% CI: −2.60, −1.10] percentage points (relative variation:−22%), respectively. Implementing an MUP on alcohol thus promises significant positive impacts on public health.

  • Performance and Inequality in Health: A Comparison of Child and Maternal Health across Asia Pré-publication, Document de travail:

    A country’s performance in health attainment refers to both its achievement (level) and its improvement (evolution) in the health domain. Studies on performance generally measure health attainment using the average health level of the population, and quantify health improvement employing the change in attainment over time. However this approach is flawed because the change in attainment does not satisfy good properties, on the one hand, and because health attainment should not only account for the average health level, but also for disparities in health in the population, on the other hand. We propose a solution to the first limitation by following the lead of Kakwani (1993), who uses achievement and improvement measures which are based on attainment measures and which satisfy important properties. For the second limitation, we extend the work of Kakwani and propose new definitions of attainment that account for the average health level but also for health inequalities in the population. Specifically, we focus on overall and social health inequalities and on the health of the poor. By including these new attainment variables into Kakwani’s indices, we generate new classes of achievement and improvement indices. Using data on 11 low and middle-income Asian countries in the twenty-first century, we highlight that child and maternal health have generally improved in recent decades, due to both an increase in the average health level and a decrease in inequalities.

  • Measuring Perceptions of Candidate Viability in Voting Experiments Chapitre d’ouvrage:

    The chapter examines perceptions of candidate viability in a series of voting experiments conducted in Lille, Montreal, and Paris. We show that: participants in these experiments are able to distinguish viable and non-viable candidates; these perceptions become clearer over time; and they affect vote choice. Moreover, we show that voters’ behavior is unaffected by whether they are asked (or not) about their perceptions of candidates’ chances of winning. We conclude that, for studying in details the determinants of voters’ choices, there is much to be gained in measuring, in a simple and direct manner, participants’ perceptions in voting experiments.

  • Addressing Europe’s democratic deficit: An experimental evaluation of the pan-European district proposal Article dans une revue:

    Many academics and commentators argue that Europe is suffering from a democratic deficit. An interesting proposal that has been put forward to address this problem is to elect some members of the European parliament in a pan-European district. In this article, we evaluate this proposal using an online experiment, in which thousands of Europeans voted on a pan-European ballot we created. We find that the voting behaviour of European citizens would be strongly affected by the presence or absence of candidates from their own country on the lists. If a pan-European district is created, our findings provide an argument in favour of using a closed-list ballot and establishing a maximum number of candidates from each country on the lists.

    Objectives. Social health inequalities remain a key policy challenge. The existing literature has not presented a synthetic view on the evolution of inequalities in physical development across childhood. We examine social disparities as children grow older using a range of different outcomes. Study design. Population-based secondary data analysis. Methods. We employ longitudinal data on British children ages 9 months to 12 years from the Millennium Cohort Study (N=13,811-18,987) and focus on multiple child physical measures: weight, BMI, overweight, fat mass, and waist circumference. Results. Higher family income is associated with lower BMI (for females), less body fat, and a smaller likelihood of overweight (for both genders) on average throughout childhood. When income is multiplied by three, the probability of overweight decreases by 2.8 (95% CI -0.041 to -0.016) percentage points for females and by 2.7 (95% CI -0.038 to -0.016) percentage points for males. Social inequalities in weight, BMI, overweight, and body fat significantly widen as children grow older, for both genders. For instance, for females, when income is multiplied by three, the probability of overweight decreases by 1.6 (95% CI -0.032 to -0.000) percentage points at ages 2-3, but by 8.6 (95% CI -0.112 to -0.060) percentage points at ages 10-12. Conclusions. The trajectory of social inequalities, which may reflect the cumulative effect of family socioeconomic status, is a precursor of inequalities in adulthood.

    Real economic commitment (or the lack of it) of others affects a person’s preferences to cooperate. But what if the commitment of others cannot be observed ex ante? Herein we examine how a classic non-monetary institution– a solemn oath of honesty –creates economic commitment within the public goods game. Commitment-through-the-oath asks people to hold themselves to a higher standard of integrity. Our results suggest the oath can increase cooperation (by 33%)– but the oath does not change preferences for cooperation. Rather people react quicker and cooperate, taking less time to ponder on the strategic free riding behavior.

  • Share capitalism and worker wellbeing Article dans une revue:

    We show that worker wellbeing is determined not only by the amount of compensation workers receive but also by how compensation is determined. While previous theoretical and empirical work has often been preoccupied with individual performance-related pay, we find that the receipt of a range of group-performance schemes (profit shares, group bonuses and share ownership) is associated with higher job satisfaction. This holds conditional on wage levels, so that pay methods are associated with greater job satisfaction in addition to that coming from higher wages. We use a variety of methods to control for unobserved individual and job-specific characteristics. We suggest that half of the share-capitalism effect is accounted for by employees reciprocating for the “gift”; we also show that share capitalism helps dampen the negative wellbeing effects of what we typically think of as “bad” aspects of job quality.

For instance, for females, when income is multiplied by 3, the probability of overweight decreases by 1.6 (95% CI −0.032 to −0.000) percentage points at ages 2–3 years, but by 8.6 (95% CI −0.112 to −0.060) percentage points at ages 10–12 years. Conclusions The trajectory of social inequalities, which may reflect the cumulative effect of family socioeconomic status, is a precursor of inequalities in adulthood.

  • Performance and Inequality in Health: A Comparison of Child and Maternal Health across Asia Chapitre d’ouvrage:

    A country’s performance in health attainment refers to both its achievement (level) and its improvement (evolution) in the health domain. Studies on performance generally measure health attainment using the average health level of the population, and quantify health improvement employing the change in attainment over time. However this approach is flawed because the change in attainment does not satisfy good properties, on the one hand, and because health attainment should not only account for the average health level, but also for disparities in health in the population, on the other hand. We propose a solution to the first limitation by following the lead of Kakwani (1993), who uses achievement and improvement measures which are based on attainment measures and which satisfy important properties. For the second limitation, we extend the work of Kakwani and propose new definitions of attainment that account for the average health level but also for health inequalities in the population. Specifically, we focus on overall and social health inequalities and on the health of the poor. By including these new attainment variables into Kakwani’s indices, we generate new classes of achievement and improvement indices. Using data on 11 low and middle-income Asian countries in the twenty-first century, we highlight that child and maternal health have generally improved in recent decades, due to both an increase in the average health level and a decrease in inequalities.

  • Individual Behavior under Evaluative Voting. A comparison between laboratory and In Situ experiments Chapitre d’ouvrage:

    This chapter compares two experimental methodologies for studying how individual voting behavior changes with respect to the choice of voting rule. We concentrate on different versions of Evaluative Voting. The results are based on two types of experimental protocol: a classical laboratory experiment with monetarily-induced preferences, and an in situ experiment run in parallel with the 2012 French presidential election. In the laboratory, individuals use the different rating scales in similar ways; but this is not the case in situ. The difference may be due to the different ways subjects interpret the proposed scales (in particular negative grades) when they concern real candidates. Finally, the chapter discusses what each method can teach us about voter behavior. Notably, we highlight behavior that is in contradiction with the tenets of strict rationality. This phenomenon, which is very widely observed in situ, and where it may be explained by a motive to express oneself, is also observed in the lab, where it is still to be explained.

  • Fluid intelligence and cognitive reflection in a strategic environment: evidence from dominance-solvable games Article dans une revue:

    Dominance solvability is one of the most straightforward solution concepts in game theory. It is based on two principles: dominance (according to which players always use their dominant strategy) and iterated dominance (according to which players always act as if others apply the principle of dominance). However, existing experimental evidence questions the empirical accuracy of dominance solvability. In this study, we study the relationships between the key facets of dominance solvability and two cognitive skills, cognitive reection and uid intelligence. We provide evidence that the behaviors in accordance with dominance and one-step iterated dominance are both predicted by one’s uid intelligence rather than cognitive reection. Individual cognitive skills, however, only explain a small fraction of the observed failure of dominance solvability. The accuracy of theoretical predictions on strategic decision making thus not only depends on individual cognitive characteristics, but also, perhaps more importantly, on the decision making environment itself.

  • Cognitive ability and the effect of strategic uncertainty Article dans une revue:

    How is one’s cognitive ability related to the way one responds to strategic uncertainty? We address this question by conducting a set of experiments in simple 2 × 2 dominance solvable coordination games. Our experiments involve two main treatments: one in which two human subjects interact, and another in which one human subject interacts with a computer program whose behavior is known. By making the behavior of the computer perfectly predictable, the latter treatment eliminates strategic uncertainty. We find that subjects with higher cognitive ability are more sensitive to strategic uncertainty than those with lower cognitive ability.

  • Reason-based choice and context-dependence: An explanatory framework Article dans une revue:

    We introduce a « reason-based » framework for explaining and predicting individual choices. The key idea is that a decision-maker focuses on some but not all properties of the options and chooses an option whose « motivationally salient » properties he/she most prefers. Reason-based explanations can capture two kinds of context-dependent choice: (i) the motivationally salient properties may vary across choice contexts, and (ii) they may include « context-related » properties, not just « intrinsic » properties of the options. Our framework allows us to explain boundedly rational and sophisticated choice behaviour. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts.

  • L’évasion fiscale est-elle un trait de personnalité ? Une évaluation empirique des déterminants psychologiques de la « morale fiscale ». Article dans une revue:

    Malgré un intérêt croissant pour les déterminants non-monétaires des comportements fiscaux (tax morale), la littérature récente apporte peu d’éléments empiriques sur le lien entre les caractéristiques de personnalité reliées à la moralité et la propension à l’évasion fiscale. Or de telles mesures sont nécessaires pour comprendre les canaux de transmission des dispositifs de lutte contre l’évasion fiscale. Pour pallier cette lacune, le présent article rend compte d’une expérience en laboratoire permettant d’observer à la fois les comportements de déclaration de revenu des participants et des mesures psychologiques issues de la littérature en psychométrie : soumission à la norme, empathie affective et cognitive, et propension à ressentir la honte et la culpabilité. Ces mesures sont combinées à l’aide d’une analyse en composantes principales afin d’en extraire les facteurs indépendants. Nos résultats montrent que la décision de frauder comme son intensité sont fortement liées à l’empathie affective, l’empathie cognitive et la dimension publique de la moralité (mesurée par la soumission à la norme et la propension à la honte). La propension à ressentir la culpabilité, en revanche, est sans effet. Surtout, le pouvoir explicatif global de ces mesures de moralité individuelles est relativement faible. Ce résultat remet en cause l’hypothèse d’une moralité fiscale intrinsèque, et met l’accent sur l’importance du contexte institutionnel pour comprendre les comportements d’évasion.

    The European Union has been actively supporting the development of regular physical activity for several health reasons [65] (COM 2007),. The Eurobarometer, published in 2013, provides statistics of sports participation and indicates that on average 58 % of Europeans engage in physical activity or sports. Nevertheless, the number of persons reporting never practicing sports or physical activity increased by 3 % since 2009 (39–42 %). In 2010, in France, two thirds of the population aged 15 and over report having practiced, over the last 12 months, one or more physical activities or sports at least once a week.

  • Electoral System and Number of Candidates: Candidate Entry under Plurality and Majority Runoff Chapitre d’ouvrage:

    We know that electoral systems have an effect on the number of competing candidates. However, a mystery remains concerning the impact of majority runoff. According to theory, the number of competing candidates should be equal (or only marginally larger) under majority runoff than under plurality. However, in real-life elections, this number is much higher under majority runoff. To provide new insights on this puzzle, we report the results of a laboratory experiment where subjects play the role of candidates in plurality and majority runoff elections. We use a candidate-only and sincere-voting model to isolate the effect of the electoral system on the decision of candidates to enter the election. We find very little difference between the two electoral systems. We thus re-affirm the mystery of the number of competing candidates under majority runoff.

  • Mentalism Versus Behaviourism in Economics: A Philosophy-of-Science Perspective Article dans une revue:

    Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people’s behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states.

  • Belief revision generalized: A joint characterization of Bayes’ and Je¤rey’s rules Article dans une revue:

    We present a general framework for representing belief-revision rules and use it to characterize Bayes’ rule as a classical example and Jeffrey’s rule as a non-classical one. In Je¤rey’s rule, the input to a belief revision is not simply the information that some event has occurred, as in Bayes’ rule, but a new assignment of probabilities to some events. Despite their differences, Bayes’ and Je¤rey’s rules can be characterized in terms of the same axioms: responsiveness, which requires that revised beliefs incorporate what has been learnt, and conservativeness, which requires that beliefs on which the learnt input is ‘silent’ do not change. To illustrate the use of non-Bayesian belief revision in economic theory, we sketch a simple decision-theoretic application.

  • Évaluation d’un programme d’activité physique adapté à des personnes âgées Rapport:

    Depuis 17 ans, l’entreprise sociale Siel Bleu développe et met en place des programmes d’activité physique adaptée aux personnes âgées en institution, dans le but de promouvoir un vieillissement actif, de prévenir les risques et les maladies chroniques liées au vieillissement et d’accompagner la dépendance. Siel Bleu intervient auprès de 80 000 bénéficiaires, dans 4000 établissements, et emploi 400 salariés. En 2012, Siel Bleu, avec l’appui de l’Union européenne et de Danone-Ecosystème, a mis en place un protocole d’évaluation portant sur un programme d’activité physique adapté destiné aux résidents de maisons de retraites : HAPPIER (Healthy Activity & Physical Program Innovations in Elderly Residences). Il s’agit de mesurer l’impact du programme sur la qualité de vie des résidents, ainsi que sur leurs facultés cognitives et physiques. Le protocole prévoyait également d’évaluer l’effet du programme sur la qualité de vie professionnelle du personnel soignant et encadrant. Les enjeux de ce protocole sont liés à l’importance grandissante de la prise en charge des personnes âgées et dépendantes par des résidences spécialisées, du fait de l’allongement de l’espérance de vie, notamment en Europe. Face à ce phénomène nouveau et massif, la qualité de vie des personnes âgées vivant en institution et le coût de leur prise en charge deviennent des questions de premier ordre. Dans ce cadre, on examine ici l’hypothèse d’un bénéfice de la pratique sportive sur l’état de santé moral et physique général des personnes âgées, ainsi que sur leur risque de chute, ces dernières constituant la source de problèmes de santé la plus grave et la plus fréquente chez les personnes âgées.

  • Mandatory labels, taxes and market forces: An empirical evaluation of fat policies Article dans une revue:

    The public-health community views mandatory Front-of-Pack (FOP) nutrition labels and nutritional taxes as promising tools to control the growth of food-related chronic diseases. This paper uses household scanner data to propose an ex-ante evaluation and comparison of these two policy options for the fromage blanc and dessert yogurt market. In most markets, labelling is voluntary and firms display fat labels only on the FOP of low-fat products to target consumers who do not want to eat fat. We here separately identify consumer preferences for fat and for FOP fat labels by exploiting an exogenous difference in legal labelling requirements between these two product categories. Estimates of demand curves are combined with a supply model of oligopolistic price competition to simulate policies. We find that a feasible ad valorem fat tax dominates a mandatory FOP-label policy from an economic perspective, but both are equally effective in reducing average fat purchases.

  • Social preferences in the online laboratory: a randomized experiment Article dans une revue:

    Internet is a very attractive technology for the implementation of experiments, both in order to obtain larger and more diverse samples and as a field of economic research in its own right. This paper reports on an experiment performed both online and in the laboratory, designed to strengthen the internal validity of decisions elicited over the Internet. We use the same subject pool, the same monetary stakes and the same decision interface, and control the assignment of subjects between the Internet and a traditional university laboratory. We apply the comparison to the elicitation of social preferences in a Public Good game, a dictator game, an ultimatum bargaining game and a trust game, coupled with an elicitation of risk aversion. This comparison concludes in favor of the reliability of behaviors elicited through the Internet. We moreover find a strong overall parallelism in the preferences elicited in the two settings. The paper also reports some quantitative differences in the point estimates, which always go in the direction of more other-regarding decisions from online subjects. This observation challenges either the predictions of social distance theory or the generally assumed increased social distance in internet interactions.

  • Attitudes to Income Inequality: Experimental and Survey Evidence Chapitre d’ouvrage:

    We review the survey and experimental findings in the literature on attitudes to income inequality. We interpret the latter as any disparity in incomes between individuals. We classify these findings into two broad types of individual attitudes toward the income distribution in a society: the normative and the comparative view. The first can be thought of as the individual’s disinterested evaluation of income inequality; on the contrary, the second view reflects self-interest, as individuals’ inequality attitudes depend not only on how much income they receive but also on how much they receive compared to others. We conclude with a number of extensions, outstanding issues, and suggestions for future research.

  • Discounting, risk and inequality: A general approach Article dans une revue:

    The common practice consists in using a unique value of the discount rate for all public investments. Endorsing a social welfare approach to discounting, we show how different public investments should be discounted depending on: the risk on the returns on investment, the systematic risk on aggregate consumption, the distribution of gains and losses, and inequality. We also study the limit value of the discount rate for very long term investments. We highlight the type of information that is needed about long-term scenarios in order to evaluate investments.

Cette corrélation peut s’interpréter selon deux chaînes causales qui font toutes deux appel à la santé des parents. Dans une première approche, le revenu familial améliorerait la santé des parents, qui elle-même influencerait positivement la santé des enfants. Dans une seconde approche, la santé des parents aurait un effet à la fois sur le revenu familial et la santé des enfants, créant par là-même une corrélation fallacieuse entre revenu et santé des enfants. L’effet des politiques publiques sur la santé des enfants sera différent selon les effets à l’oeuvre. Si le revenu des parents influence la santé des parents qui elle-même agit sur la santé des enfants, alors une politique qui augmente le revenu de certains ménages entraînera une amélioration de la santé des parents puis des enfants. Mais si la corrélation entre revenu et santé des enfants est fallacieuse, alors une politique de hausse de revenu ne se traduira pas par une amélioration de la santé des enfants. De plus, si la santé des parents a un effet causal sur la santé de leur progéniture, toute mesure permettant d’améliorer la santé des parents est susceptible de bénéficier également aux enfants. Cet article utilise les données de l’Enquête Santé et Protection Sociale de 1994-2008 pour étudier les relations entre le revenu familial et plusieurs aspects de la santé des enfants et des parents. Nos résultats suggèrent que le revenu a un impact sur la santé digestive et pondérale des enfants, indépendamment de l’effet de la santé des parents. Ce résultat pointe vers le rôle des conditions de vie dans les inégalités sociales de santé pendant l’enfance.

  • The EuroVotePlus experiment Article dans une revue:

    This paper reports on an online experiment that took place in several European countries during the three weeks before the 2014 elections for the European Parliament. We created a website where visitors could obtain information about the electoral rules used in different European Member States for this election. Participants were then invited to cast (simulated) ballots for the election according to three voting rules: closed list proportional representation, open list proportional representation with preferential voting, and open list proportional representation with cumulative voting and panachage. Participants were also invited to think about, and experiment with, the idea of electing some members of the European Parliament through pan-European party lists. The data gathered from this study enable researchers to consider the effects of electoral systems on outcomes in individual countries, and also to investigate the potential popularity and effects of Europe-wide European Parliament constituencies.

  • Adaptation and the Easterlin Paradox Pré-publication, Document de travail:

    Two behavioural explanations of the Easterlin Paradox are commonly advanced. The first appeals to social comparisons, whereby individual i compares her income (Yit) to a comparison income level earned by some other individual or group j (Y*jt). The second explanation is that of adaptation to higher levels of income. This is of the same nature, but here the individual’s current income is compared to her own income in the past (i.e. Yit is compared to Yit-τ, for some positive value or values of τ). The first of these explanations has attracted far more empirical attention than has the second. This is probably for data-availability reasons, as the investigation of the latter requires panel information. There is also a suspicion that large changes in Yit might be accompanied by a movement in some other variable that is also correlated with subjective well-being. We here review the empirical evidence that individuals do indeed compare current to past income, and then whether individuals adapt in general to aspects of their economic and social life. Last, we ask whether adaptation is in fact a viable explanation of the Easterlin Paradox.

  • Rising Aspirations Dampen Satisfaction Pré-publication, Document de travail:

    It is commonly-believed that education is a good thing for individuals. Yet its correlation with subjective well-being is most often only weakly positive, or even negative, despite the many associated better individual-level outcomes We here square the circle using novel Japanese data on happiness aspirations. If reported happiness comes from a comparison of outcomes to aspirations, then any phenomenon raising both at the same time will have only a muted effect on reported well-being. We find that around half of the happiness effect of education is cancelled out by higher aspirations, and suggest a similar dampening effect for income.

  • SWB as a Measure of Individual Well-Being Pré-publication, Document de travail:

    There is much discussion about using subjective well-being measures as inputs into a social welfare function, which will tell us how well societies are doing. But we have (many) more than one measure of subjective well-being. I here consider examples of the three of the main types (life satisfaction, affect, and eudaimonia) in three European surveys. These are quite strongly correlated with each other, and are correlated with explanatory variables in pretty much the same manner. I provide an overview of a recent literature which has compared how well different subjective well-being measures predict future behaviour, and address the issue of the temporality of well-being measures, and whether they should be analysed ordinally or cardinally.

  • Winning Big but Feeling no Better? The Effect of Lottery Prizes on Physical and Mental Health Article dans une revue:

    We use British panel data to determine the exogenous impact of income on a number of individual health outcomes: general health status, mental health, physical health problems, and health behaviours (drinking and smoking). Lottery winnings allow us to make causal statements regarding the effect of income on health, as the amount won by winners is largely exogenous. Positive income shocks have no significant effect on self-assessed overall health, but a significant positive effect on mental health. This result seems paradoxical on two levels. First, there is a well-known gradient in health status in cross-sectional data, and second, general health should partly reflect mental health, so that we may expect both variables to move in the same direction. We propose a solution to the first apparent paradox by underlining the endogeneity of income. For the second, we show that lottery winnings are also associated with more smoking and social drinking. General health will reflect both mental health and the effect of these behaviours and so may not improve following a positive income shock.

    Introduction. Dans le contexte du vieillissement de la population, il semble important de mieux comprendre comment les inégalités sociales de santé évoluent au cours de la vie. Cet article s’intéresse à la corrélation entre le statut socioéconomique et la santé et au changement de cette corrélation avec l’âge. Matériel-Méthodes. Les données proviennent de l’Enquête sur la Santé et la Protection Sociale entre 2004 et 2012. L’échantillon contient des individus âgés de 20 à 65 ans et compte environ 40000 observations. Le statut socioéconomique est mesuré par le niveau d’éducation et de revenu, tandis que la santé est quantifiée à l’aide de la variable de santé subjective. Les modèles économétriques régressent la santé sur le statut socioéconomique d’une part, et sur un ensemble de termes d’interaction entre le statut socioéconomique et les groupes d’âge d’autre part. Les régressions tiennent compte des caractéristiques démographiques des individus ainsi que de leur cohorte de naissance. Résultats. Le statut socioéconomique est positivement corrélé à l’état de santé. L’association entre revenu et santé commence par se renforcer au début de l’âge adulte, avant d’atteindre un palier, puis de décroître après 55 ans. Discussion-Conclusion. Les inégalités sociales de santé se renforcent, se stabilisent, puis s’affaiblissent à l’âge adulte en France. Ces changements pourraient trouver leur source dans les styles de vie et les conditions de travail.

    In several cantons in Switzerland the regional government, i.e. a set of governors who share the executive power in the canton, is elected according to an original voting rule, in which voters can vote for several candidates (up to a maximal number of votes). Up to some details, these elections are instances of what is known in Social Choice Theory as “Committee Approval Voting”. The paper makes use of data from a panel survey collected during the 2011 Zurich cantonal election to check whether a strategic voting theory is consistent with individual behaviour observed during that election. We show that roughly 70% of the individual decisions on candidates are consistent with our model of rational voting.

    This paper studies the heterogeneity of the marginal propensity to consume out of wealth using French household surveys. We find decreasing marginal propensity to consume out of wealth across the wealth distribution for all net wealth components. The marginal propensity to consume out of financial assets tends to be higher compared with the effect of housing assets, except in the top of the wealth distribution. Consumption is less sensitive to the value of the main residence than to other housing assets. We also investigate the heterogeneity arising from indebtedness and from the role of housing assets as collateral.

  • Strategic Voting under Committee Approval: A Theory Pré-publication, Document de travail:

    We propose a theory of strategic voting under “Commitee Approval”: a fixed-sized commitee of M members is to be elected; each voter votes for as many candidates as she wants, and the M candidates with the most votes are elected. We assume that voter preferences are separable and that there exists a tiny probability that any vote might be misrecorded. We show that best responses involve voting by pairwise comparisons. Two candidates play a critical role: the weakest expected winner and the strongest expected loser. Expected winners are approved if and only if they are preferred to the strongest expected loser and expected losers are approved if and only if they are preferred to the weakest expected winner. At equilibrium, if any, a candidate is elected if and only if he is approved by at least half of the voters. With single-peaked preferences, an equilibrium always exists, in which the first M candidates according to the majority tournament relation are elected.

Then it shows that this bargaining method ensures that both players obtain at least their average and median utility level in equilibrium. Finally it proves that, provided that the players are partially honest, the mechanism triggers sincerity and ensures that no alternative Pareto dominates the outcome of the game.

  • Wage comparisons in and out of the firm Article dans une revue:

    This paper looks at the association between wage satisfaction and other people’s pay, based on a matched employer–employee dataset. Three notions of reference wage appear to be being of particular importance: (i) the median wage level in one’s firm, (ii) the level of wage of similar workers in the region, and (iii) the top 1% wage in one’s firm. The first one triggers a signal effect, whereby all employees – especially young ones – whatever their relative position in the firm, are happier the higher the median wage in their firm, holding their own wage constant. The second and the third ones are sources of relative deprivation, i.e. workers’ satisfaction decreases with the gap between their own salary and these reference categories. These findings are based on objective measures of earnings as well as subjective declarations about wage satisfaction, awareness of other people’s pay and reported income comparisons.

  • Stubborn learning Article dans une revue:

    The paper studies a specific adaptive learning rule when each player faces a unidimensional strategy set. The rule states that a player keeps on incrementing her strategy in the same direction if her utility increased and reverses direction if it decreased. The paper concentrates on games on the square [0,1]×[0,1] as mixed extensions of 2×2 games. We study in general the behavior of the system in the interior as well as on the borders of the strategy space. We then describe the system asymptotic behavior for symmetric, zero-sum, and twin games. Original patterns emerge. For instance, for the “prisoner’s dilemma” with symmetric initial conditions, the system goes directly to the symmetric Pareto optimum. For “matching pennies,” the system follows slowly expanding cycles around the mixed strategy equilibrium.

  • Stockholding in France: the role of financial literacy and information Article dans une revue:

    We use an original household survey to study the links between stockholding, financial literacy and acquisition of financial information within the French population. Controlling for subjective expectations on stock market returns and for risk aversion, we find that stock market participation is positively related to basic financial literacy and financial information acquisition through the press reading and the family financial context during childhood. We also find that basic financial literacy is not correlated with the share of stocks in financial assets conditionally on stockownership, while the correlation with information acquisition is significant.

  • Les disparités sociales de santé perçue au cours de la vie : le cas de la France (2004-2012) Article dans une revue:

    Introduction – Dans le contexte du vieillissement de la population, il semble important de mieux comprendre comment les inégalités sociales de santé évoluent au cours de la vie. Cet article s’intéresse à la corrélation entre le statut socioéconomique et la santé perçue, et au changement de cette corrélation avec l’âge. Matériel et méthodes – Les données proviennent de l’Enquête sur la santé et la protection sociale (ESPS) entre 2004 et 2012. L’échantillon contient des individus âgés de 20 à 65 ans et compte environ 40 000 observations. Le statut socioéconomique est mesuré par le niveau d’éducation et de revenu, tandis que la santé est quantifiée à l’aide de la variable de santé subjective. Les modèles économétriques régressent la santé sur le statut socioéconomique d’une part, et sur un ensemble de termes d’interaction entre le statut socioéconomique et les groupes d’âge d’autre part. Les régressions tiennent compte des caractéristiques démographiques des individus ainsi que de leur cohorte de naissance. Résultats – Le statut socioéconomique est positivement corrélé à l’état de santé. L’association entre revenu et santé perçue commence par se renforcer au début de l’âge adulte, avant d’atteindre un palier puis de décroître après 55 ans. Discussion-conclusion – Les inégalités sociales de santé se renforcent, se stabilisent, puis s’affaiblissent à l’âge adulte en France. Ces changements pourraient trouver leur source dans les styles de vie et les conditions de travail.

  • Rising aspirations dampen satisfaction Article dans une revue:

    It is commonly believed that education is a good thing for individuals. Yet, its correlation with subjective well-being is most often only weakly positive, or even negative, despite the many associated better individual-level outcomes. We here square the circle using novel Japanese data on happiness aspirations. If reported happiness comes from a comparison of outcomes to aspirations, then any phenomenon raising both at the same time will have only a muted effect on reported well-being. We find that around half of the happiness effect of education is cancelled out by higher aspirations, and suggest a similar dampening effect for income.

  • Risk management, housing and stockholding Article dans une revue:

    This article investigates the possible explanations of the stockholding puzzle by focusing on housing and other uninsurable risks (associated with income, health and business). Taking the French household wealth survey (Patrimoine 2004, French National Statistical Institute), we find that the share of financial wealth invested in stocks depends on transaction and information costs, risk aversion, exposure to real estate risk and, to a lesser extent, labour market risk. These results are obtained by controlling for endogenous home ownership status.

  • Poverty Profiles and Well-Being: Panel Evidence from Germany Chapitre d’ouvrage:

    We consider the link between poverty and subjective well-being, and focus in particular on the role of time. We use panel data on 49,000 individuals living in Germany from 1992 to 2012 to uncover three empirical relationships. First, life satisfaction falls with both the incidence and intensity of contemporaneous poverty. Second, poverty scars: those who have been poor in the past report lower life satisfaction today, even when out of poverty. Last, the order of poverty spells matters: for a given number of years in poverty, satisfaction is lower when the years are linked together. As such, poverty persistence reduces well-being. These effects differ by population subgroups.

  • Hospital Employment and Local Unemployment: Evidence from French Health Reforms Pré-publication, Document de travail:

    We here ask whether French local authorities respond to depressed local labour markets by increasing employment in State-owned hospitals. We use 2006-2010 panel data to examine within-hospital employment changes: higher local unemployment is associated with greater employment in State-owned hospitals, but not for any other hospital type. Our data cover a reimbursement reform introducing competition between hospitals. This reform reduced public-hospital employment, but had no overall effect on the relationship between public-hospital employment and local unemployment. Further analysis shows that this continuing relationship is only found in higher unemployment areas, where public-hospital employment remained counter-cyclical.

  • Could French and Eurozone Savers Invest More in Risky Assets? Article dans une revue:

    During the crisis, French savers are turning even more towards safe, short-term assets or real estate and away from more risky and long-term financial investments. This state of affairs is a cause of concern to some analysts, who are looking for ways to encourage households to take more risks and put more of their savings into productive investment. Theoretical and statistical analysis show that this reluctance to invest in the stock market comes as much from the supply side – transaction costs in the broad sense, relatively unfavourable taxation that reduces the expected return – as from the demand side – lack of financial education among savers, aversion to risks perceived as being too high, exposure to other risks (income, unemployment, family, health, housing, human capital). In this article, after analyzing financial behaviours in France and Europe, we propose a number of propositions for redirecting savings towards more risky investments.

  • Social- and self-image concerns in fair-trade consumption Article dans une revue:

    Social interactions may alter the purchase of fair-trade food products by triggering social- or self-image concerns. We identify these concerns by eliciting the willingness-to-pay (WTP) premium for fair-trade vs. non-fair-trade chocolate of subjects under various conditions. We find that both social- and self-image matter: (i) subjects’ WTP premium for fair-trade is higher when their decisions are made public; and (ii) subjects revise this premium upward (downward) when their expectations about the premium of others increase (decrease). However, there are significant asymmetries. Making decisions public decreases the WTP for non-fair-trade chocolate rather than increases the WTP for fair-trade chocolate. Downward revisions of the premium are larger and more frequent than upward revisions.

  • Do High Consumers of Sugar-Sweetened Beverages Respond Differently to Price Changes? A Finite Mixture IV-Tobit Approach Article dans une revue:

    This study compares the impact of sugar-sweetened beverages (SSBs) tax between moderate and high consumers in Australia. The key methodological contribution is that price response heterogeneity is identified while controlling for censoring of consumption at zero and endogeneity of expenditure by using a finite mixture instrumental variable Tobit model. The SSB price elasticity estimates show a decreasing trend across increasing consumption quantiles, from −2.3 at the median to −0.2 at the 95th quantile. Although high consumers of SSBs have a less elastic demand for SSBs, their very high consumption levels imply that a tax would achieve higher reduction in consumption and higher health gains. Our results also suggest that an SSB tax would represent a small fiscal burden for consumers whatever their pre-policy level of consumption, and that an excise tax should be preferred to an ad valorem tax.

  • Retirement and the Marginal Utility of Income Pré-publication, Document de travail:

    The individual level of subjective well-being (SWB) has been shown to predict a number of future observable outcomes. Behaviour may however also be affected by the slope of SWB with respect to certain variables. We here use latentclass analysis to model both intercept and slope heterogeneity in the SWB-income relationship, and construct a continuous measure of the marginal utility of income. We show this marginal utility does predict future behaviour: those who value income more (who have a higher income elasticity of well-being) are less likely to retire. This correlation is found conditional on both the level of income and the level of well-being.

  • Citizens’ preferences about voting rules: self-interest, ideology, and sincerity Article dans une revue:

    This paper studies the determinants of citizens’ preferences for different electoral systems. We use data collected through a large internet-based quasi-experiment carried out during the 2012 French presidential election where we invited subjects to cast a vote for real candidates according to four voting rules: two-round (the official system), one-round, the alternative vote, and approval voting. After voting with each of the four voting rules, subjects were also asked to report which system they liked the most. We find that voters prefer systems that are beneficial to the candidate they prefer, that their preference for the official two-round system (weakly) depends on how they actually vote under this system, and that right-wing voters are more supportive of voting rules under which one can vote for only one candidate (one-round and two-round).

  • Early Maternal Employment and Non-cognitive Outcomes in Early Childhood and Adolescence: Evidence from British Birth Cohort Data Pré-publication, Document de travail:

    We analyse the relationship between early maternal employment and child emotional and behavioural outcomes in early childhood and adolescence. Using rich data from a cohort of children born in the UK in the early 1990s, we find little evidence of a strong statistical relationship between early maternal employment and any of the emotional outcomes. However, there is some evidence that children whose mother is in full-time employment at the 18th month have worse behavioural outcomes at ages 4, 7, and 12. We suggest that these largely insignificant results may in part be explained by mothers who return to full-time work earlier being able to compensate their children: we highlight the role of fathers’ time investment and alternative childcare arrangements in this respect.

  • Parents’ education and child body weight in France: The trajectory of the gradient in the early years Pré-publication, Document de travail:

    This paper explores the relationship between parental education and offspring body weight in France. Using two large datasets spanning the 1991-2010 period, we examine the existence of inequalities in maternal and paternal education and child reported body weight measures, as well as their evolution across childhood. Our empirical specification is flexible and allows this evolution to be non-monotonic. Significant inequalities are observed for both parents’ education – maternal (respectively paternal) high education is associated with a 7.20 (resp. 7.10) percentage points decrease in the probability that the child is reported to be overweight or obese, on average for children of all ages. The gradient with respect to parents’ education follows an inverted U-shape across childhood, meaning that the association between parental education and child body weight widens from birth to age 8, and narrows afterward. Specifically, maternal high education is correlated with a 5.30 percentage points decrease in the probability that the child is reported to be overweight or obese at age 2, but a 9.62 percentage points decrease at age 8, and a 1.25 percentage point decrease at age 17. The figures for paternal high education are respectively 5.87, 9.11, and 4.52. This pattern seems robust, since it is found in the two datasets, when alternative variables for parental education and reported child body weight are employed, and when controls for potential confounding factors are included. The findings for the trajectory of the income gradient corroborate those of the education gradient. The results may be explained by an equalization in actual body weight across socioeconomic groups during youth, or by changes in reporting styles of height and weight.

  • The EuroVotePlus experiment Article dans une revue:

    This paper reports on an online experiment that took place in several European countries during the three weeks before the 2014 elections for the European Parliament. We created a website where visitors could obtain information about the electoral rules used in different European Member States for this election. Participants were then invited to cast (simulated) ballots for the election according to three voting rules: closed list proportional representation, open list proportional representation with preferential voting, and open list proportional representation with cumulative voting and panachage. Participants were also invited to think about, and experiment with, the idea of electing some members of the European Parliament through pan-European party lists. The data gathered from this study enable researchers to consider the effects of electoral systems on outcomes in individual countries, and also to investigate the potential popularity and effects of Europe-wide European Parliament constituencies.

  • Aggregation theory and the relevance of some issues to others Article dans une revue:

    I propose a relevance-based independence axiom on how to aggregate individual yes/no judgments on given propositions into collective judgments: the collective judgment on a proposition depends only on people’s judgments on propositions which are relevant to that proposition. This axiom contrasts with the classical independence axiom: the collective judgment on a proposition depends only on people’s judgments on the same proposition. I generalize the premise-based rule and the sequential-priority rule to an arbitrary priority order of the propositions, instead of a dichotomous premise/conclusion order resp. a linear priority order. I prove four impossibility theorems on relevance-based aggregation. One theorem simultaneously generalizes Arrow’s Theorem (in its general and indifference-free versions) and the well-known Arrow-like theorem in judgment aggregation.

  • Discounting, beyond Utilitarianism Article dans une revue:

    Discounted utilitarianism and the Ramsey equation prevail in the debate on the discount rate on consumption. The utility discount rate is assumed to be constant and to reflect either the uncertainty about the existence of future generations or a pure preference for the present. The authors question the unique status of discounted utilitarianism and discuss the implications of alternative criteria addressing the key issues of equity in risky situations and variable population. To do so, they introduce a class of intertemporal social objectives, named Expected Prioritarian Equally Distributed Equivalent (EPEDE) criteria. The class is more flexible than discounted utilitarianism in terms of population ethics and it disentangles risk aversion and inequality aversion. The authors show that these social objectives imply interesting modifications of the Ramsey formula, and shed new light on Weitzman’s “dismal theorem”.

  • Wealth and Consumption: French Households in the Crisis Article dans une revue:

    Relying on an original household survey (PATER survey), we document how the 2008–9 crisis affected households’ wealth, expectations, and consumption plans in France. We then show that households experiencing losses relating to their housing or their financial wealth were more likely to change their plans by reducing consumption expenditure. Moreover, our results suggest a certain degree of heterogeneity in consumption reaction across individuals depending on their level of wealth, on the composition of their consumption basket, and on the type of shocks experienced (gains/losses). Besides the direct wealth effect, our results also provide evidence of the role played by changes in expectations on consumption plans (confidence channel).

  • Happiness and Economic Growth: Lessons from Developing Countries Ouvrages:

    This volume, arising from a PSE-CEPREMAP-DIMeco conference, includes contributions by the some of the best-known researchers in happiness economics and development economics, including Richard Easterlin, who gave his name to the ‘Easterlin paradox’ that GDP growth does not improve happiness over the long run. Many chapters underline the difficulty of increasing well-being in developing countries, including China, even in the presence of sustained income growth. This is notably due to the importance of income comparisons to others, adaptation (so that we get used to higher income), and the growing inequality of income. In particular, rank in the local income distribution is shown to be important, creating a beggar-thy-neighbour effect in happiness. Wealth comparisons in China are exacerbated by the gender imbalance, as the competition for brides creates a striking phenomenon of conspicuous consumption on the housing market. Policy has to be aware of these effects. This applies in particular to those who try to use self-reported subjective well-being in order to generate a ‘social subjective poverty line’, which is a key issue in developing countries. However, the news is not only bad from the point of view of developing countries. One piece of good news is that GDP growth often seems to go hand-in-hand with lower happiness inequality, and thereby reduces the risk of extreme unhappiness.

    Our paper investigates the relationship between family income and child health in France. We first examine whether there is a significant correlation between family income and child general health, and the evolution of this relationship across childhood years. We then study the role of specific health problems, access to health care, and supplemental health insurance coverage, in the income gradient in general health. We also quantify the role of income in child anthropometric measurements. Whenever possible, we compare our results for France with those obtained for other developed countries.

  • Mesurer les préférences des épargnants : comment et pourquoi (en temps de crise) ? Article dans une revue:

    Avec ses cinq vagues de 1998 à 2011 qui comportent une forte dimension de panel, le corpus de données Pater apporte des informations complémentaires aux enquêtes Patrimoine de l’Insee sur des aspects plus subjectifs et qualitatifs des comportements patrimoniaux. Chaque questionnaire inclut une série de mesures des préférences obtenues à l’aide de différentes méthodes. En dehors des mesures » usuelles » proposées par la littérature empirique, elles proviennent d’une approche originale, fondée sur une procédure de scoring, élaborée dès 1998 et perfectionnée depuis : des questions balayant divers domaines de la vie permettent d’évaluer des indicateurs ordinaux, synthétiques et cohérents concernant les attitudes de chaque enquêté à l’égard du risque et de l’incertain, son degré d’altruisme familial et la priorité qu’il accorde au présent. Les données conduisent à ne retenir dans chacune des cinq vagues qu’un » score » pour le risque et un pour l’altruisme, mais à distinguer deux scores distincts pour la priorité accordée au présent : le degré d’impatience sur le court terme et la préférence temporelle sur le long terme. Outre ce résultat robuste, notre méthode apparaît supérieure aux autres mesures de préférences tant en ce qui concerne les propriétés statistiques et les facteurs explicatifs des quatre scores identifiés, que les corrélations entre ces différents scores ou leurs effets sur le patrimoine et les demandes d’actifs. Permettant le suivi des mêmes épargnants dans la crise, les données Pater, comme d’autres sources, mettent en évidence une moindre appétence des Français à prendre des risques dans leur épargne ou leurs choix de portefeuille. Cependant, cette évolution des comportements ne s’explique pas par un changement des préférences des épargnants, qui sont restées statistiquement stables depuis juin 2007, mais tiendrait surtout à des anticipations de plus en plus sombres concernant le rendement et le risque des actifs financiers.

  • Wealth and happiness Article dans une revue:

    Does wealth accumulation impact subjective well-being? Within a country, household wealth has been shown to improve individual well-being by providing a safety net of protection against negative income shocks, by allowing current and expected consumption flows, and by its potential use as a collateral. At the aggregate level, direct evidence about the relationship between national wealth and happiness is almost non-existent, owing to data limitations and statistical identification problems. However, aggregate wealth impacts well-being indirectly, via positive channels, such as institutional quality and improvement in health, life expectancy, and education. Wealth also brings about negative environmental degradations and other damages. The stock of accumulated wealth is also likely to affect happiness indirectly, via its influence on the rate of GDP growth, because both the level of income flows and the rate of income growth have been shown to be factors of higher well-being.

    In spite of the great U-turn that saw income inequality rise in Western countries in the 1980s, happiness inequality has dropped in countries that have experienced income growth (but not in those that did not). Modern growth has reduced the share of both the « very unhappy » and the « perfectly happy ». The extension of public amenities has certainly contributed to this greater happiness homogeneity. This new stylized fact comes as an addition to the Easterlin paradox, offering a somewhat brighter perspective for developing countries.

  • Winning big but feeling no better? The effect of lottery prizes on physical and mental health Pré-publication, Document de travail:

    We use British panel data to determine the exogenous impact of income on a number of individual health outcomes: general health status, mental health, physical health problems, and health behaviours (drinking and smoking). Lottery winnings allow us to make causal statements regarding the effect of income on health, as the amount won by winners is largely exogenous. Positive income shocks have no significant effect on self-assessed overall health, but a significant positive effect on mental health. This result seems paradoxical on two levels. First, there is a well-known gradient in health status in cross-section data, and, second, general health should partly reflect mental health, so that we may expect both variables to move in the same direction. We propose a solution to the first apparent paradox by underlining the endogeneity of income. For the second, we show that lottery winnings are also associated with more smoking and social drinking. General health will reflect both mental health and the effect of these behaviours, and so may not improve following a positive income shock.

We then reveal that there is little evidence of adaptation within a poverty spell: poverty starts bad and stays bad in terms of subjective well-being. We cannot identify any causes of poverty entry which are unambiguously associated with adaptation to poverty.

  • Racial and Ethnic Disparities in Awareness of Cancer Genetic Testing Among Online Users: Internet Use, Health Knowledge, and Socio-Demographic Correlates Article dans une revue:

    The increased availability of genetic information online has led to growing concerns regarding health disparities among racial and ethnic groups and the need to examine the role of race/ethnicity in genetic testing awareness. Online users from a national representative sample were analyzed to explain the racial/ethnic differences in genetic testing awareness. The analysis indicated that health-related knowledge, online information-seeking behaviors, and information trust of the Internet were correlated with the prediction for awareness of online genetic testing information in different ethnic groups. The study also highlights these differences and identifies the priority ranking of the factors that reflect racial gaps. These findings suggest that the diversities in amount of trust of online information sources, education initiatives of health services, and knowledge of the existence of clinical trials and Centers for Disease Control and Prevention need to be considered more closely for racial/ethnic subgroups.

  • Social Interactions and Malaria Preventive Behaviors in Sub-Saharan Africa Pré-publication, Document de travail:

    This paper examines the existence of social interactions in malaria preventive behaviors in Sub-Saharan Africa, i.e. whether an individual’s social environment has an influence on the individual’s preventive behaviors. We focus on the two population groups which are the most vulnerable to malaria (children under 5 and pregnant women) and on two preventive behaviors (sleeping under a bednet and taking intermittent preventive treatment during pregnancy). We define the social environment of the individual as people living in the same region. To detect social interactions, we calculate the size of the social multiplier by comparing the effects of an exogenous variable at the individual level and at the regional level. Our data come from 92 surveys for 29 Sub-Saharan countries between 1999 and 2012, and they cover approximately 660,000 children and 95,000 women. Our results indicate that social interactions are important in malaria preventive behaviors, since the social multipliers for women’s education and household wealth are greater than one – which means that education and wealth generates larger effects on preventive behaviors in the long run than we would expect from the individual-level specifications, once we account for social interactions.

  • Education policies and health inequalities: Evidence from changes in the distribution of Body Mass Index in France, 1981-2003 Article dans une revue:

    This paper contributes to the debate over the effectiveness of education policies in reducing overall health inequalities as compared to public health actions directed at the less-educated. Recentered Influence Function (RIF) regressions are used to decompose the contribution of education to the changing distribution of Body Mass Index (BMI) in France, between 1981 and 2003, into a composition effect (the shift in population education due to a massive educational expansion), and a structure effect (a changing educational gradient in BMI). Educational expansion has reduced overall BMI inequality by 3.4% for women and 2.3% for men. However, the structure effect on its own has produced a 10.9% increase in overall inequality for women, due to a steeper education gradient starting from the second quartile of the distribution. This structure effect on overall inequality is also large (7.6%) for men, albeit insignificant as it remains concentrated in the last decile. Educational expansion policies can thus reduce overall BMI inequalities; but attention must still be paid to the BMI gradient in education even for policies addressing overall rather than socioeconomic health inequalities.

  • Compensating the dead Article dans une revue:

    An early death is, undoubtedly, a serious disadvantage. However, the compensation of short-lived individuals has remained so far largely unexplored, probably because it appears infeasible. Indeed, short-lived agents can hardly be identified ex ante, and cannot be compensated ex post. We argue that, despite those difficulties, a compensation can be carried out by encouraging early consumption in the life cycle. In a model with heterogeneous preferences and longevities, we show how a specific social criterion can be derived from intuitive principles, and we study the corresponding optimal policy under various informational assumptions.

    We review the findings in surveys and experiments from the literature on attitudes to income inequality. We interpret the latter as any disparity in incomes between individuals. We classify these contributions into two broad groups of individual attitudes to income distribution in a society: the normative and the comparative view. The first can be thought of as the individual’s disinterested evaluation of income inequality; on the contrary, the second view reflects self-interest, as individual’s inequality attitudes depend not only on how much income they receive but also on how much they receive compared to others. We conclude with a number of extensions, outstanding issues and suggestions for future research.

  • The French Unhappiness Puzzle: the Cultural Dimension of Happiness Pré-publication, Document de travail:

    This article sheds light on the important differences in self-declared happiness across countries of similar affluence. It hinges on the different happiness statements of natives and immigrants in a set of European countries to disentangle the influence of objective circumstances versus psychological and cultural factors. The latter turn out to be of non-negligible importance. In some countries, such as France, they are responsible for the best part of the country’s unobserved idiosyncratic source of unhappiness. French natives are less happy than other Europeans, whether they live in France or outside. By contrast, immigrants are not less happy in France than they are elsewhere in Europe, but their happiness fall with the passage of time and generations. I show that these gaps in self-declared happiness have a real emotional counterpart and do not boil down to purely nominal differences.

  • Heterogeneous reactions to heterogeneity in returns from public goods Article dans une revue:

    In many cases individuals benefit differently from the provision of a public good. We study in a laboratory experiment how heterogeneity in returns and uncertainty about the own return affects unconditional and conditional contribution behavior in a linear public goods game. The elicitation of conditional contributions in combination with a within subject design allows us to investigate belief-independent and type-specific reactions to heterogeneity. We find that, on average, heterogeneity in returns decreases unconditional contributions but affects contributions only weakly. Uncertainty in addition to heterogeneity reduces conditional contributions slightly. Individual reactions to heterogeneity differ systematically. Selfish subjects and one third of conditional cooperators do not react to heterogeneity whereas the reactions of the remaining conditional cooperators vary. A substantial part of heterogeneity in reactions can be explained by inequity aversion with respect to different reference groups.

  • Bequests and family traditions: the case of nineteenth century France Article dans une revue:

    Like father, like son: is the bequest behavior of children “inherited” from that of their parents? Most economic models (altruistic, paternalistic or exchange models) postulate that bequest behavior does not depend per se on parents’ behavior. Yet because of data limitations, few empirical studies have analyzed the link between bequests left and inheritances received. In this paper, we evaluate the effect of inheritance relative to lifetime income on the amount that individuals bequeath, in the case of France. This study uses original historical data including wealth genealogies covering the nineteenth and first half of the twentieth centuries for the Loire Inférieure département. Empirical evidence suggests that the propensity to bequeath is much greater for inheritance than for human resources: a deceased having inherited twice the average wealth leaves 35–60 % more to his own heirs that the average for his generation. In nineteenth century France, bequests are explained more by inheritance received than by personal savings per se.

Our results indicate that there are social interactions in malaria preventive behaviors in the form of social multipliers effects of women’s education and household wealth. The long-run effects of these characteristics on preventive behaviors at the regional level are larger than those apparent at the individual level.

  • Bien ou mal payés ? Ouvrages:

    Le salaire est une composante essentielle du niveau de vie. Son montant présente pour l’immense majorité des travailleurs un enjeu considérable. Comment les différents salariés perçoivent-ils à la fois le salaire qu’ils touchent et les écarts qui le séparent de celui des autres ? Portant sur les modalités subjectives de la perception des salaires ainsi que sur les critères de justice auxquels se réfèrent les individus pour évaluer leur montant, les deux grandes enquêtes dont est issu cet ouvrage mettent au jour les relations que les travailleurs entretiennent avec leur salaire ainsi que le sens qu’ils attribuent à leur rémunération. Un même questionnaire, l’enquête « SalSa » (« les salaires vus par les salariés »), a été administré à un échantillon de salariés des entreprises, privées et publiques, d’un côté, et à un échantillon de salariés de la fonction publique de l’autre. Il ressort de ces enquêtes que, du point de vue des salariés, le salaire ne se réduit jamais à une simple somme d’argent destinée à satisfaire des besoins. C’est aussi une façon de mesurer la valeur du travail accompli, sa reconnaissance par la société et donc la valeur de la personne elle-même, en soi mais aussi en relation avec les autres. C’est pourquoi la façon dont les individus connaissent, appréhendent et jugent leur rémunération et celle des autres est un élément essentiel pour comprendre les procédures de détermination et donc de négociation des salaires, mais aussi le sens que les individus attribuent à leur travail.

  • L’économie du bonheur Ouvrages:

    Nos sociétés ont fait du bonheur une idée neuve, un principe constitutionnel, presque un devoir. Le bonheur de l’individu est devenu l’objectif suprême des choix politiques. Mais peut-on mesurer quelque chose d’aussi subjectif et impalpable que le bonheur ? Depuis une trentaine d’années, les économistes ont tenté de relever ce défi. Ils ont fait le pari de mesurer le bonheur tel qu’il est ressenti et déclaré par les individus eux-mêmes. Leur enquête concerne plus particulièrement le rôle de la richesse. L’argent fait-il le bonheur ? La croissance rend-elle les gens plus heureux ? Dans le cas contraire, faut-il opter pour la décroissance ou, du moins, mesurer le bien-être au-delà du PIB ? Ce passionnant champ de recherches permet de comprendre pourquoi la France, pays objectivement riche, souffre d’un tel « déficit de bonheur ».

  • The French unhappiness puzzle: The cultural dimension of happiness Article dans une revue:

    This article sheds light on the important differences in self-declared happiness across countries of similar affluence. It hinges on the different happiness statements of natives and immigrants in a set of European countries to disentangle the influence of objective circumstances versus psychological and cultural factors. The latter turn out to be of non-negligible importance. In some countries, such as France, they are responsible for the best part of the country’s unobserved idiosyncratic source of unhappiness. French natives are less happy than other Europeans, whether they live in France or outside. By contrast, immigrants are not less happy in France than they are elsewhere in Europe, but their happiness fall with the passage of time and generations. I show that these gaps in self-declared happiness have a real emotional counterpart and do not boil down to purely nominal differences.

  • What Predicts a Successful Life? A Life-course Model of Well-being Article dans une revue:

    Policy makers who care about well-being need a recursive model of how adult life-satisfaction is predicted by childhood influences, acting both directly and (indirectly) through adult circumstances. We estimate such a model using the British Cohort Study (1970). We show that the most powerful childhood predictor of adult life-satisfaction is the child’s emotional health, followed by the child’s conduct. The least powerful predictor is the child’s intellectual development. This may have implications for educational policy. Among adult circumstances, family income accounts for only 0.5% of the variance of life-satisfaction. Mental and physical health are much more important.

  • Economic Growth Evens-Out Happiness: Evidence from Six Surveys Pré-publication, Document de travail:

    In spite of the great U-turn that saw income inequality rise in Western countries in the 1980s, happiness inequality has fallen in countries that have experienced income growth (but not in those that did not). Modern growth has reduced the share of both the “very unhappy” and the “perfectly happy”. Lower happiness inequality is found both between and within countries, and between and within individuals. Our cross-country regression results argue that the extension of various public goods helps to explain this greater happiness homogeneity. This new stylised fact arguably comes as a bonus to the Easterlin paradox, offering a somewhat brighter perspective for developing countries.

  • Consommation et patrimoine des ménages : au-delà du débat macroéconomique… Article dans une revue:

    L’impact de la valeur du patrimoine sur la consommation des ménages est en général étudié au niveau macroéconomique. L’analyse de cet effet richesse est particulièrement importante pour la politique économique dans le contexte récent de forte valorisation des actifs. Sur données agrégées, les estimations pour la France montrent qu’un euro de patrimoine supplémentaire entrainerait une augmentation de la consommation de 0,8 centime à 1 centime d’euro, cet effet s’avérant plus important pour le patrimoine financier que pour l’immobilier. Notre étude utilise les données de l’enquête Patrimoine 2010 pour évaluer ce même lien à partir de données individuelles. Elle s’appuie sur les différences de composition et de niveau de patrimoine pour identifier des hétérogénéités dans le comportement de consommation. Les résultats confirment que la propension marginale à consommer la richesse est globalement faible, de 0,5 centime d’euro par euro de richesse supplémentaire. Elle dépend cependant de la nature des actifs et présente de fortes non-linéarités le long de l’échelle des patrimoines. Ainsi, la propension marginale à consommer la richesse financière est de plus de 11 centimes par euro de richesse additionnelle pour les ménages dont le patrimoine net est inférieur à la médiane, alors qu’elle est nulle pour les ménages du décile le plus riche. Cet effet richesse est nettement moins élevé pour la résidence principale : 1,1 centime pour les patrimoines nets inférieurs à la médiane et 0,7 centime pour le décile le plus riche. Compte tenu de la concentration des patrimoines, l’effet richesse moyen reflète principalement le comportement des ménages les plus riches. Mais l’effet plus marqué qu’on observe pour les ménages moins aisés est un résultat à prendre en compte par les politiques monétaires et fiscales. Ces politiques n’auront pas le même impact sur la demande et la croissance selon les catégories d’actifs et les catégories de ménages qu’elles affecteront le plus.

  • What drives failure to maximize payoffs in the lab? A test of the inequality aversion hypothesis Article dans une revue:

    Experiments based on the Beard and Beil (1994) two-player coordination game robustly show that coordination failures arise as a result of two puzzling behaviors: (i) subjects are not willing to rely on others’ self-interested maximization, and (ii) self-interested maximization is not ubiquitous. Such behavior is often considered to challenge the relevance of subgame perfectness as an equilibrium selection criterion, since weakly dominated strategies are actually used. We report on new experiments investigating whether inequality in payoffs between players, maintained in most lab implementations of this game, drives such behavior. Our data clearly show that the failure to maximize personal payoffs, as well as the fear that others might act this way, do not stem from inequality aversion. This result is robust to varying the saliency of decisions, repetition-based learning and cultural differences between France and Poland.

  • Inégalités de patrimoine entre générations : les donations aident-elles les jeunes à s’installer ? Article dans une revue:

    En France, l’écart de patrimoine s’accroît entre les plus âgés et les plus jeunes qui, de plus, héritent de plus en plus tard. Différentes mesures fiscales ont tenté de pallier ce déséquilibre. En 2007, par exemple, l’abattement sur les transmissions vers les enfants a été multiplié par trois et porté à 150 000 euros. Depuis, il a été ramené à 100 000 euros. Plusieurs études montrent que les parents sont sensibles aux avantages fiscaux accordés aux donations. On peut néanmoins s’interroger sur l’impact de tels transferts : comment les donations, notamment précoces, sont-elles utilisées ? Cet article rappelle l’importance croissante que revêtent en France les transmissions et les inégalités patrimoniales entre les générations. Les données de l’enquête Insee Patrimoine 2010 permettent ensuite d’étudier l’impact des différentes formes de transmissions (entre vifs ou au décès) sur deux comportements clefs des jeunes générations : l’achat de la résidence principale et la création d’entreprise. Nous montrons que la probabilité de créer ou reprendre une entreprise est plus élevée lorsqu’une donation a été reçue mais ne l’est pas si un héritage a été perçu. La probabilité d’acheter son logement augmente, elle, avec ces deux formes de transfert. Nous proposons plusieurs mesures de l’intensité du lien entre transmissions et investissements. Ce dernier est plus fort lorsque le bénéficiaire du transfert est jeune. La hausse des prix de l’immobilier des années 2000 se serait accompagnée d’un renforcement du lien entre donation et achat du logement. Nous traitons enfin la question de l’effet causal de la donation : cette dernière favorise-t-elle la décision d’acquisition du logement ou accompagne-t-elle une décision déjà formée ? Nous utilisons le fait que la probabilité de recevoir une donation diminue avec la taille de la fratrie pour montrer que l’effet causal de la donation s’avère plus élevé que les effets jusqu’alors mis en évidence.

  • To vote or to abstain? An experimental test of rational calculus in first past the post and PR elections Article dans une revue:

    We test the rational choice model of turnout in the lab. We performed laboratory experiments in which participants had to decide whether to vote or not in a number of first past the post and proportional representation elections. We test the predictions of rational choice theory from three different angles: (i) First, we compare aggregate turnout with the Nash equilibrium predictions. (ii) Second, we compare individual decisions with those derived from a rational calculus and count the number of decisions which are consistent with the rational recommendation, and. (iii) Third, we determine, still at the individual level, whether, at the margin, people are more likely to vote as the expected payoff increases. The overwhelming thrust of the evidence is inconsistent with the rational calculus paradigm.

  • Introduction : Patrimoine et comportements d’épargne, les apports de l’enquête Patrimoine 2010 Article dans une revue:

    La parution de ce numéro spécial d’Économie et Statistique sur le patrimoine intervient au moment où le succès du livre de T. Piketty, Le capital au XXIe siècle, a réveillé l’intérêt du monde académique et du grand public pour la thématique de l’accumulation des richesses et l’enjeu que constitue la croissance des inégalités des patrimoines. La parution de ce numéro spécial tombe à point nommé pour une autre raison. La crise économique et financière que nous connaissons depuis 2008 n’a pas « épargné » les épargnants. Il est donc primordial d’étudier ce qui a changé dans leurs comportements patrimoniaux. Comme les précédents, parus respectivement en 1996, en 2005 et en 2008, ce quatrième numéro qu’Économie et Statistique consacre entièrement à l’analyse économique du patrimoine des ménages propose plusieurs articles qui, pour la plupart, prennent largement appui sur les données collectées par les enquêtes Patrimoine réalisées par l’Insee tous les 6 ans depuis 1986. Comme eux, il entend contribuer à l’économie du patrimoine des ménages, entendue comme cette partie de la discipline économique qui s’efforce de décrire les processus suivant lesquels les ménages accumulent (ou décumulent) de l’épargne, et dont l’importance s’est affirmée toujours davantage depuis trois décennies.

  • Judgment aggregation in search for the truth Article dans une revue:

    We analyse the problem of aggregating judgments over multiple issues from the perspective of whether aggregate judgments manage to efficiently use all voters’ private information. While new in judgment aggregation theory, this perspective is familiar in a different body of literature about voting between two alternatives where voters’ disagreements stem from conflicts of information rather than interests. Combining the two bodies of literature, we consider a simple judgment aggregation problem and model the private information underlying voters’ judgments. Assuming that voters share a preference for true collective judgments, we analyse the resulting strategic incentives and determine which voting rules efficiently use all private information. We find that in certain, but not all cases a quota rule should be used, which decides on each issue according to whether the proportion of ‘yes’ votes exceeds a particular quota.

  • Scoring rules for judgment aggregation Article dans une revue:

    This paper introduces a new class of judgment aggregation rules, to be called ‘scoring rules’ after their famous counterparts in preference aggregation theory. A scoring rule generates the collective judgment set which reaches the highest total ‘score’ across the individuals, subject to the judgment set having to be rational. Depending on how we define ‘scores’, we obtain several (old and new) solutions to the judgment aggregation problem, such as distance-based aggregation, premise- and conclusion-based aggregation, truth-tracking rules, and a generalization of the Borda rule to judgment aggregation theory. Scoring rules are shown to generalize the classical scoring rules of preference aggregation theory.

  • Discrimination à l’embauche selon l’origine et le genre : défiance indifférenciée ou ciblée sur certains groupes ? Article dans une revue:

    L’existence d’une discrimination raciale à l’embauche sur le marché du travail est désormais largement documentée dans la plupart des économies occidentales. Si ce phénomène est confirmé par différentes études pour le marché du travail français, les causes et les sources de cette discrimination restent quant à elles largement inconnues. Cet article présente les résultats d’une étude destinée à évaluer empiriquement les principales sources de discrimination à l’embauche en Île-de-France, en s’inspirant des développements récents de la littérature. Cette évaluation repose sur un envoi contrôlé de candidatures en réponse à des offres d’emploi postées sur des sites publics d’information. L’étude montre que la discrimination à l’embauche à l’encontre des candidats issus de l’immigration est de l’ordre de 40% en moyenne. Cette inégalité de traitement entre candidats affecte toutes les candidatures d’origine étrangère, indépendamment de l’origine du candidat, ce qui va à l’encontre de l’hypothèse d’une défiance ciblée à l’encontre de vagues particulières d’immigration. Sur la base de ces résultats, il semble donc que la question de la discrimination se pose bien plus en termes d’opposition entre le groupe majoritaire, « autochtone », et l’ensemble des individus issus de l’immigration, qu’en termes de difficultés spécifiques propres à certains groupes. En ce sens, les résultats confirment l’existence d’une « homéophilie » ethnique sous-jacente à la discrimination – c’est-à-dire d’une défiance indifférenciée de la part des employeurs à l’égard de tout candidat n’appartenant pas au groupe ethnique majoritaire. Ensuite, nos résultats indiquent que les candidatures féminines sont favorisées par rapport à leurs équivalents masculins et relativement moins affectées par la discrimination d’origine. Enfin, l’inclusion d’un signal explicite d’aisance linguistique sur la moitié des envois élimine toute discrimination liée à l’origine pour les candidatures féminines. L’effet d’un tel signal est en revanche plus faible sur la discrimination opérant entre candidatures masculines.

  • Allocation de l’épargne et investissement de long terme Ouvrages:

    L’épargnant navigue aujourd’hui sur une mer houleuse : crise financière et économique rendant l’environnement plus incertain, risque macroéconomique lié au devenir du système de protection sociale, réformes fiscales, politiques “d’activation de l’individu” cherchant à le rendre davantage responsable de son avenir… Conséquence, l’épargnant français privilégie aujourd’hui plus encore qu’hier les actifs sûrs et de court terme (augmentation des dépôts sur livrets, baisse de la collecte nette des assurances vie, etc.) et les biens immobiliers au détriment des investissements financiers risqués et de long terme. Cet état de fait inquiète certains acteurs qui cherchent les moyens d’inciter les ménages à prendre plus de risque et privilégier une épargne productive1. Avant d’entrer dans ce débat, nous ferons un “audit” statistique de la situation patrimoniale des épargnants français et européens. Pour cela, nous utiliserons toute la palette des données disponibles : aussi bien celles de la Comptabilité Nationale que celles des enquêtes auprès des ménages menées en coupe instantanée par l’Insee (enquêtes “Patrimoine”) et la Banque Centrale Européenne ou BCE (enquête HFCS). Ces données nous permettront de constater que cette “énigme de la prime de risque” sur les actifs financiers risqués n’est pas un phénomène purement français mais se généralise à la zone euro. Nous rappellerons ensuite les explications de ce “puzzle” empirique en chaussant les lunettes de l’économiste, qu’il soit plutôt adepte des théories orthodoxes ou de celles des comportementalistes : le manque d’appétence pour les placements boursiers tiendrait aussi bien à l’offre – coûts de transaction au sens large, fiscalité relativement peu avantageuse qui diminue le rendement espéré – qu’à la demande – manque d’éducation financière des épargnants, aversion au risque jugée trop élevée, exposition à d’autres risques (revenu, chômage, famille, santé, logement, capital humain). Si l’on se place du côté de la demande, les choix de portefeuille des individus dépendent de trois grandes composantes : leurs préférences (aversion au risque, préférence temporelle, etc.), leurs ressources plus ou moins disponibles ou risquées, et leurs anticipations concernant le rendement et le risque vis-à-vis du marché boursier et le revenu du travail. L’expérience “naturelle” que constitue la crise financière et économique actuelle offre un observatoire idéal pour juger de l’importance de chacun de ces facteurs. Les données longitudinales uniques des enquêtes PATER nous permettent d’étudier les réactions des épargnants durant la “grande récession”, de voir “ce qui a changé” pour expliquer la frilosité accrue des investisseurs : accroissement de l’aversion au risque, baisse des ressources, anticipations pessimistes ? Nous serons ainsi mieux à même de juger de la pertinence de certaines propositions visant à réorienter l’épargne vers des produits plus risqués.

  • Anti-terrorism policies and the risk of provoking Article dans une revue:

    Tough anti-terrorism policies are often defended by focusing on a fixed minority of the population who prefer violent outcomes, and arguing that toughness reduces the risk of terrorism from this group. This reasoning implicitly assumes that tough policies do not increase the group of ‘potential terrorists’, i.e., of people with violent preferences. Preferences and their level of violence are treated as stable, exogenously fixed features. To avoid this unrealistic assumption, I formulate a model in which policies can ‘brutalise’ or ‘appease’ someone’s personality, i.e., his preferences. This follows the endogenous preferences approach, popular elsewhere in political science and economics. I formally decompose the effect of toughness into a (desirable) deterrence effect and an (undesirable) provocation effect. Whether toughness is overall efficient depends on which effect overweighs. I show that neglecting provocation typically leads to toughness exaggeration. This suggests that some tough anti-terrorism policies observable in the present and past can be explained by a neglect of provocation.

  • Aggregating causal judgments Article dans une revue:

    Decision making typically requires judgments about causal relations: we need to know both the causal e§ects of our actions and the causal relevance of various environmental factors. Judgments about the nature and strength of causal relations often di§er, even among experts. How to handle such diversity is the topic of this paper. First, we consider the possibility of aggregating causal judgments via the aggregation of probabilistic ones. The broadly negative outcome of this investigation leads us to look at aggregating causal judgments independently of probabilistic ones. We do so by transcribing causal claims into the formal judgment-aggregation framework and applying some recent results in this field. Finally, we look at the implications for probability aggregation when it is constrained by prior aggregation of qualitative causal judgments.

En utilisant des données individuelles, nous montrons que ce constat ne concerne pas l’ensemble de la population : les couches aisées et plutôt âgées détiennent des produits risqués et de long terme de façon plutôt fréquente et importante. Par ailleurs, la prudence accrue des épargnants pendant la crise s’explique plus par des anticipations à la baisse (revenus, prix d’actifs boursiers, marché du travail) que par un accroissement de l’aversion au risque durant la crise.

  • Cultural Integration in France Chapitre d’ouvrage:

    The French Republican model appears as a polar case among the different cultural integration models. Dating back to the French Revolution and the Third Republic, France has a long secular tradition imposing restrictive attitudes on the expression of religious and cultural identity in the public sphere. There are, however, growing concerns that this model, despite its claimed egalitarianism and universalism, fails to integrate the new immigrant minorities. The most illustrative example is the 2004 ruling against the display of conspicuous religious symbols in school, mainly targeted at Muslim schoolgirls who wished to wear the hijab. The main consequence of this refusal to acknowledge any minorities has been an inability to know whether the reality of equality matches the rhetoric of perfect cultural integration. While views on national identity and the integration model are very strongly held in France, the evidence base is rather weak. The goal of this chapter is to fill this gap.

  • Preference Elicitation under Oath Article dans une revue:

    Eliciting sincere preferences for non-market goods remain a challenge due to the discrepency between hypothetical and real behavior and false zeros. The gap arises because people either overstate hypothetical values or understate real commitments or a combination of both. Herein we examine whether the traditional real-world institution of the solemn oath can improve preference elicitation. Applying the social psychology theory on the oath as a truth-telling-commitment device, we ask our bidders to swear on their honour to give honest answers prior to participating in an incentive-compatible second-price auction. The oath is an ancillary mechanism to commit bidders to bid sincerely in a second-price auction. Results from our induced valuation testbed treatments suggest that the oath-only auctions outperform all our other auctions (real and hypothetical). In our homegrown valuation treatments eliciting preferences for dolphin protection, the oath-only design induced people to treat as binding both their experimental budget constraint (i.e., lower values on the high end of the value distribution) and participation constraint (i.e., positive values in place of the zero bids used to opt-out of auction). Based on companion treatments, we show the oath works through an increase in the willingness to tell the truth, due to a strengthening of the intrinsic motivation to do so.

  • Obésité – Santé publique et populisme alimentaire Ouvrages:

    L’obésité n’est pas seulement un enjeu de santé publique. Son développement questionne notre modèle alimentaire et, au-delà, notre modèle de production agroalimentaire. Les industriels ne s’y sont pas trompés, cachant une défense de ce modèle productif sous les habits de la gastronomie et du plaisir gustatif. De fait, ce sont bien les arbitrages des consommateurs entre santé et plaisir qui, in fine, déterminent le succès ou l’échec des politiques d’alimentation et de santé nutritionnelle. Mais font-ils ces arbitrages de manière souveraine et pleinement responsable ? À cette question, centrale pour la construction d’une politique alimentaire cohérente, Fabrice Étilé répond par la négative. C’est bien l’environnement et l’offre alimentaire qu’il faut changer, et les comportements suivront. Dans cette perspective, il propose un ensemble de pistes d’action combinant étiquetage, fiscalité, régulation de l’environnement alimentaire et réforme des filières agroalimentaires.

  • Family income and child health in the UK Pré-publication, Document de travail:

    Recent studies examining the relationship between family income and child health in the UK have produced mixed findings. We re-examine the income gradient in child general health and its evolution with child age in this country, using a very large sample of British children. We find that there is no correlation between income and child general health at ages 0-1, that the gradient emerges around age 2 and is constant from age 2 to age 17. In addition, we show that the gradient remains large and significant when we try to address the endogeneity of income. Furthermore, our results indicate that the gradient in general health reflects a greater prevalence of chronic conditions among lowincome children and a greater severity of these conditions. Taken together, these findings suggest that income does matter for child health in the UK and may play a role in the intergenerational transmission of socioeconomic status.

  • Using or Hiding Private Information? An Experimental Study of Zero-Sum Repeated Games with Incomplete Information Article dans une revue:

    This paper studies the value of private information in strictly competitive interactions in which there is a trade-off between (i) the short-run gain of using information, and (ii) the long-run gain of concealing it. We implement simple examples from the class of zero-sum repeated games with incomplete information. While the empirical value of information does not always coincide with the theoretical prediction, the qualitative properties of the value of information are satisfied in the laboratory: (i) it is never negative, (ii) it decreases with the number of repetitions, (iii) it is bounded below by the value of the infinitely repeated game, and (iv) it is bounded above by the value of the one-shot game. In line with the theory, the empirical use of private information is almost complete when it should be, and decreases in longer interactions.

  • Poverty and Well-Being: Panel Evidence from Germany Pré-publication, Document de travail:

    We consider the link between poverty and subjective well-being, and focus in particular on the role of time. We use panel data on 42,500 individuals living in Germany from 1992 to 2010 to uncover four empirical relationships. First, life satisfaction falls with both the incidence and intensity of contemporaneous poverty. There is no evidence of adaptation within a poverty spell: poverty starts bad and stays bad in terms of subjective well-being. Third, poverty scars: those who have been poor in the past report lower life satisfaction today, even when out of poverty. Last, the order of poverty spells matters: for a given number of poverty spells, satisfaction is lower when the spells are concatenated: poverty persistence reduces well-being. These effects differ by population subgroups.

  • Learning, political attitudes and crises: Lessons from transition countries Article dans une revue:

    This paper illustrates the sensitivity of political attitudes to the business cycle. It shows how the 2008 economic crisis has reshaped individual support for democracy and market liberalization in post-transition countries. Pro-reform attitudes have lost ground between 2006 and 2010 in Central and Eastern European countries that were hit by a negative economic shock. By contrast, they have increased in the CIS. Although on average, individual exposure to the crisis is associated with lower support to democracy and markets, it drives the demand for liberal reforms among groups of the population that were most excluded from the political-economic system in place, the youth particularly, in countries that lag behind in terms of liberalization and, where institutions are corrupt. We propose an interpretation of these evolutions in terms of learning and updating of beliefs.

  • Financial Literacy and Financial Planning in France Article dans une revue:

    We study financial literacy in France using the PATER survey and following the Lusardi and Mitchell (2011c) approach. We find that some subpopulations are less financially literate than others: women, young and old people as well as less-educated people are more likely to face difficulties when dealing with fundamental financial concepts such as risk diversification and inflation and interest compounding. We also find some differences in financial knowledge depending on the political opinion of the respondents. Finally we show that these differences in financial knowledge are correlated with differences in the propensity to plan: people who score higher on the financial literacy questions are more likely to be engaged in the preparation of a clearly defined financial plan.

  • Measuring savers’ preferences how and why? Pré-publication, Document de travail:

    Measuring individual preferences of savers have two main motivations: to reduce the share of non-observed heterogeneity in explaining households’ wealth behaviors, and to construct more accurate tests of the theories of savings and portfolio choices. For France, we have constructed a unique data set, the PAT€R surveys (PATrimony and Preferences vis-à-vis Time and Risk), with the first survey made in 1998 by interview with Insee, and the following surveys conducted by Tns-Sofres via postal questionnaires: PAT€R-2002 focused on the transmission of preferences between parents and children; the three subsequent waves, PAT€R-2007-2009-2011, were conducted in May 2007 (before the crisis), June 2009 and November 2011, on more than 3600 households representative of the French population, with an important panel dimension – about 2000 households were interviewed at least twice, and nearly 1100 households were present in all three waves. Almost each survey replicates direct measures of risk attitudes as well as time preference found in the literature, such as the hypothetical lottery on income of Barsky et al. (1997), selfreported 0-to-10 scales concerning the willingness to take risks in various contexts (Dohmen et al., 2011), or even experimental measures. Yet these measures, based upon a limited number of questions, suffer from serious drawbacks that are analyzed in the paper. This is why we have developed an alternative method of scoring in order to measure three types of preferences, towards risk, time, and offspring (altruism) : synthetic and ordinal scores of preferences are derived from the responses given to a large number of (mainly) simple real-life questions covering different life domains of life (consumption, leisure, health, investments, work, retirement, family). No single question is satisfactory by itself, but the idea is that if a number of questions possess a common dimension, towards risk for instance, this dimension will be isolated by aggregating the replies, beyond framing effects, measurement errors, etc.: the score obtained will then show enough internal consistency, as measured by psychometric tests. Ultimately, the data will thus determine how many indicators – if any – should be introduced for each type of preference. On the five surveys, this scoring method has proved very consistent and robust. Derived from some 60 questions, one single score of preference towards risk was sufficient in each wave (with Cronbach’s alpha near 0.7). As regards time depreciation, two scores were each time necessary, marking the contrast between the short term and impulsive choices (« short-term impatience ») on the one hand, and the long term and more reasoned decisions « time preference » over the life cycle) on the other. One single score of altruism was retained. he contents of these four scores are very similar from one wave to the next, as well as their individual determinants, their individual correlation over time, the degree of correlation between scores, etc. Finally, the effect of these scores on the level and composition of wealth are similar across surveys, in line with theoretical predictions, and more significant than those obtained for alternate measures of preferences which suffer, moreover, from endogeneity biases.

  • Taxing more (large) family bequests: why, when, where? Pré-publication, Document de travail:

    There is a capital taxation puzzle in most developed countries. Since the 1960s, revenues from wealth transfer taxation have been especially low and decreasing as a percentage of GDP, even to the extent of disappearing in quite a number of cases; by contrast, lifetime wealth or capital taxation generates much higher revenues and shows no decreasing trend. The full tax puzzle is certainly not easy to explain. Many usual explanations of the aversion to wealth transfer taxation also imply limited lifetime capital taxation: they cannot justify the very strong collective preference for lifetime capital taxation observed in most countries. On the other hand, capital market imperfections may explain higher levels of lifetime capital taxation, but not the diverging trends of the two components of capital taxation. We think that a key explanatory factor of the tax puzzle in general and of the growing unpopularity of wealth transfer taxation in particular stems from the rising role of family values and links: the family appears to be the only safe investment nowadays in the face of risky globalized markets and the feared retrenchment of the welfare state. Any realistic reform must take this social and political constraint into account. Most reformist economists think that lifetime wealth or capital taxation could act as quite an efficient substitute for too unpopular taxes on wealth transfers. We offer an alternative solution which recommends heavier and more progressive taxation on family inheritances (only) while allowing for various legal loopholes to avoid the tax. It could hence prompt parents driven by family altruism to increase (early) inter vivos transfers to their progeny and people driven by social altruism to make more charitable gifts and bequests, and would bring in additional and welcome revenues.

  • Learning, Words and Actions: Experimental Evidence on Coordination-Improving Information Article dans une revue:

    We experimentally study an asymmetric coordination game with two Nash equilibria: one is Pareto-efficient, the other is Pareto-inefficient and involves a weakly dominated strategy. We assess whether information about the interaction partner helps eliminate the imperfect equilibrium. Our treatments involve three information-enhancing mechanisms: repetition and two kinds of individual signals: messages from partner or observation of his past choices. Repetition-based learning increases the frequencies of the most efficient outcome and the most costly strategic mismatch. Moreover, it is superseded by individual signals. Like previous empirical studies, we find that signals provide a screening of partners’ intentions that reduces the frequency of coordination failures. Unlike these studies, we find that the transmission of information between partners, either via messages or observation, does not suffice to significantly increase the overall efficiency of outcomes. This happens mostly because information does not restrain the choice of the dominated action by senders.

  • Prevention against equality? Article dans une revue:

    Common sense supports prevention policies aimed at improving survival prospects among the population. It is also widely acknowledged that an early death is a serious disadvantage, and that attention should be paid to the compensation of short-lived individuals. This paper re-examines the compatibility of those two concerns: prevention against early death and compensation for early death. We show that, under mild conditions, no social ordering on allocations can satisfy a concern for prevention and a concern for compensation. The reason is that if it is socially desirable to raise the number of survivors through prevention, it must also be, under costly prevention, desirable to deteriorate the living standards of the short-lived. We then explore two approaches to the prevention/compensation dilemma, and study the associated optimal allocation of resources.

  • Back to Baseline in Britain: Adaptation in the British Household Panel Survey Article dans une revue:

    We look for evidence of adaptation in wellbeing to major life events using eighteen waves of British panel data. Adaptation to marriage, divorce, birth of child and widowhood appears to be rapid and complete; this is not so for unemployment. These findings are remarkably similar to those in previous work on German panel data. Equally, the time profiles with life satisfaction as the wellbeing measure are very close to those using a twelve-item scale of psychological functioning. As such, the phenomenon of adaptation may be a general one, rather than being found only in German data or using single-item wellbeing measures.

  • Family income and child health in the UK Article dans une revue:

    Recent studies examining the relationship between family income and child health in the UK have produced mixed findings. We re-examine the income gradient in child general health and its evolution with child age in this country, using a very large sample of British children. We find that there is no correlation between income and child general health at ages 0-1, that the gradient emerges around age 2 and is constant from age 2 to age 17. In addition, we show that the gradient remains large and significant when we reduce the endogeneity of income. Furthermore, our results indicate that the gradient in general health reflects a greater prevalence of chronic conditions among low-income children and a greater severity of these conditions. Taken together, these findings suggest that income does matter for child health in the UK and may play a role in the intergenerational transmission of socioeconomic status.

  • Social comparisons, health and well-being Article dans une revue:

    Health and well-being are socially determined. One of the ways in which this comes about is via social comparisons with other individuals in the same personal, geographic or social networks, with the comparisons referring either to income or other aspects of economic and social life. The existence of such comparison effects with respect to income may help to explain the social gradient in health.

  • Inequality and bi-polarization in socioeconomic status and health: Ordinal approaches Pré-publication, Document de travail:

    Traditional indices of bi-dimensional inequality and polarization were developed for cardinal variables and cannot be used to quantify dispersion in ordinal measures of socioeconomic status and health. This paper develops two approaches to the measurement of inequality and bi-polarization using only ordinal information. An empirical illustration is given for 24 European Union countries in 2004-2006 and 2011. Results suggest that inequalities and bi-polarization in income and health are especially large in Estonia and Portugal, and that inequalities have significantly increased in recent years in Austria, Belgium, Finland, Germany, and the Netherlands, whereas bi-polarization significantly decreased in France, Portugal, and the UK.

  • Fair Retirement Under Risky Lifetime Pré-publication, Document de travail:

    A premature death unexpectedly brings a life and a career to their end, leading to substantial welfare losses. We study the retirement decision in an economy with risky lifetime, and compare the laissez-faire with egalitarian social optima. We consider two social objectives: (1) the maximin on expected lifetime welfare (ex ante), allowing for a compensation for unequal life expectancies; (2) the maximin on realized lifetime welfare (ex post), allowing for a compensation for unequal lifetimes. The latter optimum involves, in general, decreasing lifetime consumption profiles, as well as raising the retirement age, unlike the ex ante egalitarian optimum. This result is robust to the introduction of unequal life expectancies and unequal productivities. Hence, the postponement of the retirement age can, quite surprisingly, be defended on egalitarian grounds –although the conclusion is reversed when mortality strikes only after retirement.

  • For richer, for poorer”: savings preferences and choice of spouse Pré-publication, Document de travail:

    Do couples share the same values? The social sciences have mainly concentrated on comparing the socioeconomic characteristics of spouses, but rarely their preferences to risk and time. In this paper, we use conventional measurements and an original method. We find that spouses are very similar in their savings preferences, even when we control for the individual characteristics. These conclusions are decisive in explaining wealth inequalities between households, since homogamy causes a divide in the population. However, if the correlation between preferences and wealth is clear when measured at the household level, spouses with opposite attitudes tend to be richer for some parameters.

  • Childhood Sporting Activities and Adult Labour-Market Outcomes Pré-publication, Document de travail:

    We here ask whether sports participation at school is positively correlated with adult labour-market outcomes. There are many potential channels for this effect, although, as usual, identifying a causal relationship is difficult. We appeal to two widely-separated waves of Add Health data to map out the correlation between school sports and adult labour-market outcomes. We show that different types of school sports are associated with different types of jobs and labour-market insertion when adult. We take the issue of the endogeneity of sport seriously and use data on siblings in order to obtain estimates that are as close to unbiased as possible. Last, we compare the effect of sporting activities to that of other leisure activities.

  • Malaria prevalence, indoor residual spraying, and insecticide-treated net usage in Sub-Saharan Africa Pré-publication, Document de travail:

    This paper analyzes the effect of malaria prevalence and indoor residual spraying on the probability of sleeping under an insecticide-treated bed net in nine Sub-Saharan countries. Specifically, it examines whether bed net usage is elastic with respect to malaria prevalence and whether indoor residual spraying, which is a public intervention, crowds out bed net usage, which is a private behavior. Using data on individual bed net usage and household indoor residual spraying combined with local malaria prevalence, we show that malaria prevalence has a positive effect on bed net usage, but that bed net usage is inelastic with respect to malaria prevalence, with elasticity ranging from 0.42 for adult women to 0.59 for older children, in our preferred model. We also find that indoor residual spraying does not crowd out bed net usage. Instead, individuals who live in houses that were recently sprayed are more likely to use a bed net.

  • Wage Comparisons in and out of the Firm. Evidence from a Matched Employer-Employee French Database Pré-publication, Document de travail:

    This paper looks at the association between wage satisfaction and different notions of reference wage, based on a matched employer-employee dataset. It shows that workers’ satisfaction depends on otherpeople’s income in different ways. Relative income concerns are important, but we also find robust evidence of signal effects. For instance, workers are happier the higher the median wage in their firm, holding their own wage constant. This is true of all employees, whatever their relative position in the firm. This signal effect is stronger for young people and for women. These findings are based on objective measures of earnings as well as subjective declarations about wage satisfaction, awareness of other people’s wage and reported income comparisons.

    Our paper investigates the relationship between family income and child health in France. We first examine whether there is a significant correlation between family income and child general health, and the evolution of this relationship across childhood years. We then study the role of specific health problems, the use of health care services, and supplemental health insurance coverage, in the income gradient in general health. We also quantify the role of income in child anthropometric measurements. Whenever possible, we compare our results for France with those obtained for other developed countries.

  • Are « daddy’s boys » just as rich as daddy? The transmission of values between generations Article dans une revue:

    The influence of parents’ savings behaviour on that of their children has often been remarked. This paper attempts to explain this « poids d’Anchise » via a unique French dataset collected by DELTA and TNS-Sofres in 2002 (Pat€r survey), which contains both savings and subjective information for two or three generations of the same family. Parents’ and children’s risk and discounting preferences are significantly positively intergenerationally correlated. The correlation coefficients are around 0.25, so that the two preferences are nonetheless far from identical. In addition, the elasticity of children’s wealth with respect to that of their parents is around 0.22. This correlation is corrected for the influence of age on wealth, and concerns only co-existing generations, that is before the most significant intergenerational transfers have taken place. The analysis of the raw correlations with a series of explanatory variables reveals that over 40 % of this elasticity can be explained by the permanent incomes of the two generations. Each of education and preferences separately account for about 20 %, and previous intergenerational transfers for about 13 %. When permanent income is controlled for, the contribution of savings preferences is around 13 %. The transmission of preferences therefore plays a non-negligible role in the intergenerational transmission of wealth inequalities, but is far from being the most important factor.

  • Obésité : santé publique et populisme alimentaire Ouvrages:

    Les questions alimentaires voient rituellement s’affronter promoteurs de la santé publique et défenseurs du plaisir gustatif. Une telle mise en scène fait l’impasse sur la manière dont les consommateurs concilient habituellement plaisir et santé. En nous intéressant de près à cet arbitrage, nous voulons replacer les consommateurs au centre du débat public, en tant qu’objets mais aussi en tant qu’acteurs des politiques publiques d’alimentation et de santé. Nous sommes arrivés au terme d’une transition nutritionnelle et alimentaire marquée par une hausse continuelle de nos apports en calories, en graisses et en sucres, une demande croissante de produits transformés et cuisinés, un recours accru à la restauration hors du foyer, et un affaiblissement du modèle alimentaire français dans les jeunes générations. L’entrée dans l’ère de l’abondance alimentaire se paie par une explosion du surpoids et de l’obésité, avec des inégalités sociales qui révèlent les déterminants majeurs des arbitrages entre plaisir et santé. Les progrès technologiques de l’agro-industrie ont favorisé la mise sur le marché de produits peu chers, riches en graisses, en sucres et en sel ajoutés, apportant des satisfactions faciles. Pourquoi renoncer à ces promesses de plaisir « low cost » quand on a un horizon de vie bouché et des conditions d’existence peu réjouissantes ? Les efforts que nous faisons pour investir dans notre santé et dans notre corps, comme nous y invitent les campagnes de recommandations nutritionnelles, dépendent en premier lieu de ce que nous pouvons espérer y gagner. Pour autant, l’État ne doit pas abandonner toute ambition régulatrice en matière d’alimentation et de santé, au prétexte que le consommateur serait souverain et que l’offre se contenterait de satisfaire la demande. Car nos arbitrages entre plaisir et santé sont souvent imparfaits et erronés. Le marketing alimentaire nous conduit à manger plus que nous le souhaiterions. La consommation de produits gras et sucrés déforme notre goût et conditionne nos choix ultérieurs, à la manière d’une addiction. Notre environnement alimentaire fait finalement pencher la balance du côté du plaisir bien au-delà de ce qui suffirait à satisfaire nos intérêts. Une politique de régulation de l’environnement alimentaire pourrait s’appuyer sur quatre piliers : 1) un étiquetage nutritionnel utilisant le système des feux tricolores (vert-orange-rouge), fonction du profil nutritionnel des aliments, apposé sur la face avant des produits préemballés ; 2) une réallocation des aliments aux différents taux de TVA en fonction de leurs profils nutritionnels, avec un affichage saillant de la TVA ; 3) une régulation stricte des dispositifs marchands poussant à l’augmentation des quantités consommées (promotions, publicités à destination des enfants, etc.), et une régulation de l’architecture des choix dans les lieux d’achat et de restauration ; 4) une politique agro-industrielle favorisant la production d’aliments incorporant moins de graisses, de sucres et de sel ajoutés. Ce paquet de mesures se justife par les violations de la souveraineté du consommateur observées sur les marchés alimentaires. De telles prémisses peuvent être discutées. On peut également contester le droit de l’État à réguler ainsi l’environnement pour peser sur nos choix. Les différentes options politiques en présence mettent finalement en jeu des valeurs de liberté et de protection de la santé publique, mais aussi d’équité et d’efficacité économique. Pour trancher, il est urgent d’organiser en France un débat sur l’avenir que nous souhaitons pour notre alimentation. Puisqu’il s’agit de leurs arbitrages entre plaisir et santé, les consommateurs doivent être impérativement placés au centre du processus de délibération et de fabrication des politiques publiques, a!n que soit restaurée une forme de souveraineté collective sur nos choix alimentaires, à défaut d’une souveraineté individuelle.

  • La discrimination à l’embauche, Sur le marché du travail Français. Ouvrages:

    La discrimination est une question récurrente du débat public : l’insertion sur le marché du travail est-elle différente entre hommes et femmes ? Qu’en est-il des conditions d’emploi ? Les inégalités d’accès à ces ressources concernent-elles aussi les personnes issues de l’immigration ? Et surtout, ces différences observées sur le marché du travail sont-elles bien dues à une inégalité de traitement à l’encontre de ces différentes catégories de population ? Si oui, pour quelles raisons ? Répondre à ces questions va bien au-delà des seuls débats théoriques: l’identification des mesures appropriées pour créer les conditions d’une véritable égalité des chances nécessite de comprendre l’ampleur, les sources et les causes des comportements discriminatoires. Cet ouvrage propose un état des lieux des connaissances actuelles sur la nature, la mesure et l’ampleur de la discrimination à l’embauche sur le marché du travail français. Nous présentons ensuite les résultats d’une nouvelle étude destinée à explorer les sources de la discrimination observée. La méthode utilisée permet de comparer le succès relatif de différents candidats en fonction du groupe d’appartenance suggéré par leur identité. La première dimension que nous étudions concerne le rôle du favoritisme ethnique: la discrimination s’exerce-t-elle à l’encontre de minorités ethniques particulières et clairement identifiées, ou plus généralement à l’encontre de toute personne n’appartenant pas au groupe majoritaire ? Ensuite, nous croisons cette dimension ethnique avec le genre des individus, afin de mesurer non seulement les discriminations hommes/femmes mais aussi le rôle du genre dans les discriminations liées à l’origine. Enfin, nous évaluons l’influence de la maîtrise de la langue française sur les chances de succès des candidats issus de l’immigration. Les résultats de notre étude montrent que la discrimination à l’embauche à l’encontre des candidats issus de l’immigration est de l’ordre de 40%en moyenne : à profil de compétences égal, un candidat appartenant à cette catégorie de population doit envoyer près d’une fois et demie plus de candidatures pour être invité au même nombre d’entretiens d’embauche. Cette inégalité de traitement entre candidats affecte toutes les candidatures d’origine étrangère, indépendamment de l’origine du candidat, ce qui va à l’encontre l’hypothèse d’une défiance ciblée à l’encontre de vagues particulières d’immigration. En ce sens, la question de la discrimination se pose donc bien plus en termes d’opposition entre le groupe majoritaire, « autochtone » et l’ensemble des individus issus de l’immigration, qu’en termes de difficultés spécifiques propres à certains groupes. Loin de confirmer la discrimination de genre souvent discutée, nous observons un léger favoritisme en faveur des candidatures féminines, et ce pour l’ensemble des types d’emploi considérés. Ce résultat s’explique, en partie, par la tendance des employeurs de genre féminin à privilégier les candidats à l’embauche de même sexe. De plus, nos résultats indiquent que la discrimination d’origine affecte davantage les candidatures masculines que les candidatures féminines. L’ensemble de ces constats suggère que les attentes des employeurs en termes de compétences et d’adéquation à l’emploi varient fortement en fonction du genre des candidats issus de l’immigration. Cette hypothèse est confirmée indirectement par l’effet du degré de maîtrise du langage apparaissant dans les candidatures. La mention explicite de cette compétence suffit à faire disparaître la prime dont bénéficient les candidatures féminines françaises, et élimine toute discrimination d’origine dans cette catégorie de candidatures. En revanche, la maîtrise de la langue française ne réduit qu’à la marge le degré de discrimination liée à l’origine our les candidatures masculines. Cet effet différencié suggère que la discrimination à l’encontre des individus masculins issus de l’immigration recouvre une dimension bien plus vaste que les seules considérations liées au maniement de la langue française. Nous proposons pour conclure une discussion de l’efficacité attendue et des limites des dispositifs de lutte contre les discriminations à la lumière de ces résultats – anonymat des CV, programmes de discrimination positive. Une piste qui reste peu explorée consiste à agir sur les caractéristiques observables des candidats défavorisés, en instaurant par exemple un instrument de certification de la maîtrise de la langue française.

  • Corporate social responsibility and the economics of consumer social responsibility Article dans une revue:

    La diffusion de la Responsabilité sociale des entreprises (CSR) est conditionnée par les comportements d’achat des consommateurs. Nombre d’entre eux déclarent être favorables à la CSR et pourtant, la consommation responsable reste à un niveau faible. Cette revue de la littérature analyse deux barrières principales à la consommation responsable : la disponibilité-à-payer des consommateurs, qui dépend de leurs préférences sociales ; et l’asymétrie d’information entre les entreprises et les consommateurs. La littérature économique montre que les préférences sociales des consommateurs dépendent de leurs préoccupations en termes d’altruisme, d’image de soi et d’image sociale et que seuls les consommateurs avec des préférences sociales fortes et une utilité marginale du revenu faible (hauts revenus) sont enclins à acheter des produits CSR. Par ailleurs, les décisions d’achat dépendent de l’existence de labels qui identifient véritablement les produits CSR. Les politiques publiques peuvent promouvoir la responsabilité sociale des consommateurs à travers des programmes d’éducation et d’amélioration des considérations d’image de soi et d’image sociale, et une régulation précise des labels.

  • Money, Well-Being, and Loss Aversion: Does an Income Loss Have a Greater Effect on Well-Being Than an Equivalent Income Gain? Article dans une revue:

    Higher income is associated with greater well-being, but do income gains and losses affect well-being differently? Loss aversion, whereby losses loom larger than gains, is typically examined in relation to decisions about anticipated outcomes. Here, using subjective-well-being data from Germany (N = 28,723) and the United Kingdom (N = 20,570), we found that losses in income have a larger effect on well-being than equivalent income gains and that this effect is not explained by diminishing marginal benefits of income to well-being. Our findings show that loss aversion applies to experienced losses, challenging suggestions that loss aversion is only an affective-forecasting error. By failing to account for loss aversion, longitudinal studies of the relationship between income and well-being may have overestimated the positive effect of income on well-being. Moreover, societal well-being might best be served by small and stable income increases, even if such stability impairs long-term income growth.

  • L’apport de l’économie expérimentale dans l’élaboration des politiques publiques Article dans une revue:

    La capacité des expériences en laboratoire à inspirer l’élaboration et l’évaluation des politiques publiques a été reconnue très tôt dans l’histoire de son développement (Roth, 1988). Ce n’est que très récemment, pourtant, que cette question a émergé avec force dans les discussions académiques, notamment sous l’impulsion des travaux consacrés au paternalisme libéral. Cette doctrine d’élaboration des politiques publiques s’attache à redéfinir les principes libéraux de choix libres et décentralisés à la lumière des développements de l’économie comportementale – qui identifient les limites cognitives des choix rationnels. Nous proposons une introduction et un survol de ce courant de pensée, ainsi qu’un certain nombre d’exemples des conclusions de politique publique sur lesquelles il débouche. Nous confrontons ces arguments et ces conclusions à ceux d’une seconde branche de la littérature, qui s’efforce de restaurer les conditions d’un choix libre et éclairé à travers le développement d’institutions qui permettent aux individus de dépasser ces limites cognitives ; et/ou d’identifier les sources institutionnelles de ces limites de la rationalité, de manière à en circonscrire les effets. Nous concluons cette présentation par une discussion des complémentarités entre ces deux approches qui, bien que diamétralement opposées, fournissent une grille de lecture des liens qu’entretiennent l’économie comportementale et l’élaboration des politiques publiques.

La méthode expérimentale est conçue de manière à répliquer un environnement microéconomique prédéfini et observer le comportement d’individus réels interagissant au sein de cet environnement. Les comportements observés peuvent ainsi être confrontés aux prédictions théoriques des modèles sous-jacents. Cet article vise précisément à présenter un certain nombre d’illustrations issues de cette confrontation. La présentation aborde successivement la question de la validité du théorème de Coase, l’étude de la politique de la concurrence, l’efficacité des modes de résolution des litiges et l’analyse des comportements criminels.

  • Discriminations à l’embauche : quelle ampleur, quelles solutions ? Article dans une revue:

    La discrimination à l’embauche est aujourd’hui bien comprise, grâce aux travaux qui en mesurent l’ampleur et les causes à partir d’envois contrôlés de candidatures fictives. Ces résultats confirment que la discrimination constitue un handicap majeur pour les candidats issus de l’immigration : près de 40 % de chances en moins d’être convoqués à un entretien d’embauche. Mais loin de refléter une simple défiance à l’égard des individus issus de l’immigration, ces discriminations s’expliquent aussi largement par la difficulté pour un employeur à anticiper les caractéristiques d’un candidat issu d’un groupe différent du sien. Ces résultats ouvrent la voie à des nouveaux instruments de lutte contre les discriminations, qui consistent à améliorer l’information disponible sur les compétences du candidat.

  • Mandatory Labels, taxes and market forces : An empirical evaluation of fat policies Communication dans un congrès:

    The public-health community views the mandatory labelling and taxation of fat as promising tools to control the growth of food-related chronic disease. This paper is the first to propose an ex ante evaluation of these two policy options in an oligopolistic setting with differentiated products and heterogeneous demand. Using household scanner data on fromages blancs and dessert yogurts, we separately identify consumer preferences for fat and front-of-pack fat labels by exploiting an exogenous difference in legal labelling requirements between these two product categories. Demand estimates are then combined with a supply model to evaluate both policies. In the absence of any producer price response, making fat labels mandatory reduces the fat supplied to regular consumers in this market by 38%; an ad-valorem tax of 10% (5%) on the producer price of full-fat (half-skimmed) products has a similar impact. Allowing producer price reactions, however, yields much smaller effects: a 9% drop for the fat tax, and a fall of only 1:5% for mandatory labels. Producers thus neutralise up to 96% of the impact of mandatory labelling on demand, via large price cuts on products with large ex ante margins. This illustrates how market forces are largely able to defeat the intended effect of market-based public-health interventions.

  • Chapitre 9 : Rémunération mixte et comportement professionnel des spécialistes Chapitre d’ouvrage:

    Jusqu’en 1999, le mode de rémunération largement dominant chez les médecins spécialistes du Québec était la rémunération à l’acte. Ce mode permet le paiement de tout acte médical posé par un médecin, selon les tarifs en vigueur établis par le Ministère de la santé et des services sociaux (MSSS) et les fédérations médicales. Cependant, en septembre 1999, le MSSS et la Fédération des médecins spécialistes du Québec (FMSQ) se sont entendus sur la mise en oeuvre d’un nouveau mode de rémunération des activités en établissement des spécialistes: la rémunération mixte. Cette rémunération optionnelle combine salariat et rémunération partielle à l’acte. L’objectif de cette réforme consistait en particulier à augmenter le temps consacré aux patients ainsi que certaines tâches non rémunérées sous la rémunération à l’acte, tels l’enseignement et les tâches administratives. L’impact de la réforme est potentiellement très important puisqu’en 2010, près de 50% des médecins spécialistes avaient adhéré à ce nouveau mode de rémunération.

  • Prevention against equality? Pré-publication, Document de travail:

    Common sense supports prevention policies aimed at improving survival prospects among the population. It is also widely acknowledged that an early death is a serious disadvantage, and that attention should be paid to the compensation of short-lived individuals. This paper re-examines the compatibility of those two concerns: prevention against early death and compensation for early death. We show that, under mild conditions, no social ordering on allocations can satisfy a concern for prevention and a concern for compensation. The reason is that if it is socially desirable to raise the number of survivors through prevention, it must also be, under costly prevention, desirable to deteriorate the living standards of the short-lived. We then explore two approaches to the prevention / compensation dilemma, and study the associated optimal allocation of resources.

  • La taxation nutritionnelle comme outil de santé publique: justifications et effets attendus Article dans une revue:

    Cet article discute la littérature économique sur les politiques de taxation nutritionnelle. Il présente notamment les résultats empiriques relatifs à la taxation des boissons sucrées. L’analyse historique montre clairement les liens existants entre les évolutions des prix alimentaires et celles de la qualité du régime alimentaire moyen. La création d’une taxe nutritionnelle peut alors être motivée par le souci de protéger le consommateur, ou par la volonté de minimiser les coûts médicaux des excès alimentaires. En pratique, les consommateurs peuvent aisément opérer des substitutions entre aliments, et les firmes peuvent modifier le prix et la qualité de leurs produits. Ces réactions adaptatives sont susceptibles de neutraliser l’effet espéré d’une taxe, quel que soit son design : l’effet comportemental et l’impact sur la santé publique seront faibles, du moins à des niveaux conventionnels de taxation (entre 5 et 20 %). En revanche, la taxation reste un moyen de lever des recettes fiscales, qui doivent impérativement être affectées de manière équitable à des programmes de promotion de la santé nutritionnelle pour espérer susciter l’adhésion de la population.

  • The causes of happiness and misery Chapitre d’ouvrage:

    Chapter 3 discusses the causes of happiness and misery, based on 30 years of research on the topic. Both external and personal features determine well-being. Some of the important external factors include income, work, community and governance, and values and religion. More “personal” factors include mental and physical health, family experience, education, gender, and age. Many of these factors have a two-way interaction with happiness – physical health may improve happiness, while happiness improves physical health. An analysis of all these factors strikingly shows that while absolute income is important in poor countries, in richer countries comparative income is probably the most important. Many other variables have a more powerful effect on happiness, including social trust, quality of work, and freedom of choice and political participation.

  • You can’t be happier than your wife. Happiness gaps and divorce Article dans une revue:

    Based on three large panel surveys, this paper shows that happiness gaps between spouses are a good predictor of future divorce. The effect of happiness gaps is asymmetric: couples are more likely to break-up when the woman is the less happy partner. De facto, divorces appear to be initiated predominantly by women who are less happy than their husband. This asymmetry suggests that the effect of happiness gaps is grounded on motives of relative deprivation (i.e. comparisons of happiness between spouses) rather than on a preference for equal happiness.

  • The Great Happiness Moderation Pré-publication, Document de travail:

    This paper shows that within-country happiness inequality has fallen in the majority of countries that have experienced positive income growth over the last forty years, in particular in developed countries. This new stylized fact comes as an addition to the Easterlin paradox, which states that the time trend in average happiness is flat during episodes of long-run income growth. This mean-preserving declining spread in happiness comes about via falls in both the share of individuals who declare low and high levels of happiness. Rising income inequality moderates the fall in happiness inequality, and may even reverse it after some point, for example in the US starting in the 1990s. Hence, if raising the income of all does not raise the happiness of all, it will at least harmonize the happiness of all, providing that income inequality does not grow too much. Behind the veil of ignorance, lower happiness inequality would certainly be considered as attractive by risk-averse individuals.

  • Social- and Self-Image Concerns in Fair-Trade Consumption: Evidence from Experimental Auctions for Chocolate Pré-publication, Document de travail:

    Can social interactions be used to encourage the consumption of fair-trade products? Social interactions may alter purchase behavior by triggering either self-image concerns (when one sees others’ decisions without being seen) or social-image concerns (when everybody sees everyone else). A laboratory experiment is designed to identify separately these concerns, using real auctions for normal and fair-trade chocolate, controlling for taste and packaging differences. The analysis of the willingness-to-pay (WTP) for both types of chocolate reveals that both social- and self-image matter: subjects pay a higher premium for fair-trade chocolate when their decisions are made public. This premium is sensitive to information received about the premia paid by other subjects, even when decisions are private. The higher premium in public auctions results from a lower WTP for normal chocolate, rather than a higher WTP for fair-trade chocolate. Subjects are also much more sensitive to information about others’ choices that relaxes the moral or social norm constraining their own choice. We thus conclude that social interactions cannot be used to nudge consumers into fair-trade consumption, at least for ordinary products such as chocolate.

  • Mandatory labels, taxes and market forces: An empirical evaluation of fat policies Pré-publication, Document de travail:

    The public-health community views the mandatory labelling and taxation of fat as promising tools to control the growth of food-related chronic disease. This paper is the first to propose an ex ante evaluation of these two policy options in an oligopolistic setting with differentiated products and heterogeneous demand. Using household scanner data on fromages blancs and dessert yogurts, we separately identify consumer preferences for fat and front-of-pack fat labels by exploiting an exogenous difference in legal labelling requirements between these two product categories. Demand estimates are then combined with a supply model to evaluate both policies. In the absence of any producer price response, making fat labels mandatory reduces the fat supplied to regular consumers in this market by 38%; an ad-valorem tax of 10% (5%) on the producer price of full-fat (half-skimmed) products has a similar impact. Allowing producer price reactions, however, yields much smaller effects: a 9% drop for the fat tax, and a fall of only 1:5% for mandatory labels. Producers thus neutralise up to 96% of the impact of mandatory labelling on demand, via large price cuts on products with large ex ante margins. This illustrates how market forces are largely able to defeat the intended effect of market-based public-health interventions.

  • Signaling Corporate Social Responsibility: Third-Party Certification vs. Brands Pré-publication, Document de travail:

    For most consumers, Corporate Social Responsibility is a credence attribute of products, which can be signaled either through a label certified by a third party, or via unsubstantiated claims used as part of a brand-building strategy. These claims may, in theory, be regulated by reputation mechanisms and the awareness of NGOs and activists. We use an experimental posted-offer market with sellers and buyers to compare the impact of these signalling strategies on market efficiency. Both third-party certification and the possibility of CSRrelated brand building give rise to a separating equilibrium. However, only third-party certification clearly produces efficiency gains, by increasing CSR investments. In markets where reputation matters little, unsubstantiated claims can generate a ‘halo’ effect on consumers, whereby the latter are nudged into paying more for the same level of CSR investments by firms.

  • Indiscriminate Discrimination: A Correspondence Test for Ethnic Homophily in the Chicago Labor Market Article dans une revue:

    Numerous field experiments have demonstrated the existence of discrimination in labor markets against specific minority groups. This paper uses a correspondence test to determine whether this discrimination is due to prejudice against specific groups, or a general preference for the majority group. Three groups of identical fabricated resumes are sent to help-wanted advertisements in Chicago newspapers: one with Anglo-Saxon names, one with African-American names, and one with fictitious foreign names whose ethnic origin is unidentifiable to most Americans. Resumes with Anglo-Saxon names generate nearly one third more call-backs than identical resumes with non Anglo-Saxon ones, either African-American or Foreign. We take this as evidence that discriminatory behavior is part of a larger pattern of unequal treatment of any member of non-majority groups, ethnic homophily.

  • Taxer les héritages pour accroître la mobilité du patrimoine entre générations les inégalités entre générations Article dans une revue:

    De rendement limité et de plus en plus impopulaire, la taxation des héritages est souvent justifiée par un souci de justice sociale et de redistribution : inégalité des chances, revenu d’aubaine immérité, concentration et reproduction élevées des fortunes, etc. Dans un pays comme la France, marquée par un fort déséquilibre intergénérationnel en faveur des séniors, une autre justification de cet impôt est cependant possible, à savoir l’accélération, via la famille, de la circulation du patrimoine vers les jeunes générations. Une taxation plus forte et progressive des seuls héritages familiaux redonnerait un avantage fiscal aux donations aux enfants, plus souvent altruistes, ainsi qu’aux dons ou legs caritatifs. L’analyse historique et économétrique montre que la mesure serait efficace : les donations augmenteraient en conséquence et les réceptions précoces faciliteraient les projets patrimoniaux des enfants (acquisition du logement, création d’entreprise).

  • The value of diplomacy: Bilateral relations and immigrant well-being Pré-publication, Document de travail:

    Ce papier traite de la question de la valeur, en termes de bien-être, des bonnes relations entre pays, par le biais de l’analyse d’un groupe d’individus liés aux deux pays : les immigrés. Nous faisons appel à un indice de conflit et coopération calculé comme une somme pondérée du nombre de communiqués de presse entre deux pays. Cet indice est ensuite apparié à un échantillon d’immigrés en Allemagne dans les données du SOEP. Notre mesure des relations bilatérales varie donc non seulement dans le temps mais aussi entre immigrés venant de pays différents. Nous observons une relation positive et significative entre la satisfaction dans la vie des immigrés et la qualité des relations bilatérales entre le pays d’accueil et le pays d’origine. Cet effet est plus marqué pour les immigrés présents en Allemagne depuis plus longtemps et qui veulent y rester. Ce résultat témoigne de l’effet direct des relations internationales sur la qualité de la vie quotidienne des immigrés dans le pays d’accueil, un effet qui semble contradictoire avec l’hypothèse assimilation. L’effet de la diplomatie sur le bien-être est donc positive.

  • Democracy, Market Liberalization and Political Preferences Article dans une revue:

    This paper questions the conventional wisdom concerning the sequencing of political and economic reforms in developing countries. We exploit the specific situation of frontier-zones as well as the considerable regional variations in culture and economic development in the countries of Central and Eastern Europe and the former Soviet Union. We estimate the impact of market development and democratization on subjective political preferences. Taking advantage of a new survey conducted in 2006 by the European Bank for Reconstruction and Development and the World Bank in 28 post-transition countries, we find a positive and significant effect of democracy on support for a market economy, but no effect of market liberalization on support for democracy. Our results are robust to the use of various indices of market liberalization and democracy and alternative measures of political preferences.

  • Is happiness different from flourishing? Cross-Country Evidence from the ESS Article dans une revue:

    Il a souvent été reproché aux mesures subjectives du bonheur de privilégier une approche hédonique de l’existence, au détriment d’autres aspects essentiels de la vie humaine tels que l’épanouissement personnel, la signification de la vie, l’espace de choix et les opportunités ouvertes aux individus. Cet article compare différentes mesures de bien-être subjectif contenues dans une enquête auprès de 30 000 individus résidents dans 21 pays européens (European Social Survey) afin de vérifier la congruence entre les aspects hédoniques, eudaimoniques, cognitifs et émotionnels du bien-être. De fait, les mesures de bonheur, de satisfaction, de vitalité, de résilience, d’épanouissement et de capacité à fonctionner sont très fortement corrélées au niveau individuel. De plus, les mêmes facteurs expliquent ces différents aspects du bien-être. Cependant, la congruence n’est pas parfaite: ainsi les hommes se déclarent-ils en moyenne moins heureux mais plus satisfaits de leur vie et font-ils preuve d’un niveau d’épanouissement plus élevé que les femmes.

  • You can’t be happier than your wife. Happiness Gaps and Divorce Pré-publication, Document de travail:

    Cet article montre que plus la différence de bien-être subjectif entre conjoints est grande, plus leur risque de divorcer est élevé (en contrôlant pour le niveau de bien-être des conjoints). Même mesuré au cours de la première année de mariage, un écart de bien-être prédit un divorce ultérieur. Cette relation tient même pour les couples dont les deux membres sont identifiés comme étant plus heureux que dans une série de situations alternatives hors-mariage. Mise en évidence à l’aide de trois grandes enquêtes de panel, cette observation témoigne de l’importance des comparaisons de bien-être et de la notion d’utilité relative. Il est possible que la divergence de bien-être soit plus dangereuse lorsque les transferts d’utilité sont plus difficiles. Il est également possible que les mariages fondés sur un appariement sélectif soient plus stables. Mais cela n’explique pas entièrement notre découverte. En effet, une augmentation de l’écart de bien-être au cours du temps accroît également le risque de divorce. Enfin, l’effet mis en évidence est asymétrique: seuls les couples au sein desquels la femme est moins heureuse que l’homme sont menacés de dissolution. L’effet observé semble donc relever de comparaison de bien-être plutôt que d’une aversion pour l’inégalité (sans quoi les femmes plus heureuses divorceraient elles aussi). Cet argument n’a jamais été pris en compte dans les modèles économiques du mariage. Il est pourtant de nature à éclairer les choix individuels au sein de la famille et devrait être pris en considération par les mesures de politique publiques qui influencent les décisions individuelles, notamment d’offre de travail, susceptibles de faire diverger les niveaux d’utilité des conjoints.

  • The organisational commitment of workers in OECD countries Pré-publication, Document de travail:

    L’identification des salariés avec l’entreprise où ils travaillent, et l’effort qu’ils consacrent à leur travail, semblent être des variables clefs pour une meilleure compréhension de la productivité au travail, des salaires et du turnover. Dans cet article, nous faisons appel aux données ISSP de 1997 et 2005 afin de modéliser trois mesures de l’engagement des travailleurs par rapport à leur entreprises dans les pays de l’OCDE. Cet engagement est très variable selon les pays, et ces différences sont difficiles à expliquer par les caractéristiques des travailleurs ou des postes qu’ils occupent. Cependant, ces écarts sont corrélés avec certaines variables macroéconomiques. L’inflation et le chômage sont négativement corrélés avec nos mesures de l’engagement des salariés, alors que ces dernières sont positivement associées à des indices de liberté économique et sociale.

  • A model of non-informational preference change Article dans une revue:

    According to standard rational choice theory, as commonly used in political science and economics, an agent’s fundamental preferences are exogenously fixed, and any preference change over decision options is due to Bayesian information learning. Although elegant and parsimonious, such a model fails to account for preference change driven by experiences or psychological changes distinct from information learning. We develop a model of non-informational preference change. Alternatives are modelled as points in some multidimensional space, only some of whose dimensions play a role in shaping the agent’s preferences. Any change in these ‘motivationally salient’ dimensions can change the agent’s preferences. How it does so is described by a new representation theorem. Our model not only captures a wide range of frequently observed phenomena, but also generalizes some standard representations of preferences in political science and economics.

  • Stepping Off the Hedonic Treadmill: Individual Differences in Response to Marriage, Divorce, and Spousal Bereavement Article dans une revue:

    Theorists have long maintained that people react to major life events but then eventually return to a setpoint of subjective well-being. Yet prior research is inconclusive regarding the extent of interindividual variability. Recent theoretical models suggest that there should be heterogeneity in long-term stress responding (Bonanno, 2004; Muthén & Muthén, 2000). To test this idea, we used latent growth mixture modeling to identify specific patterns of individual variation in response to three major life events (bereavement, divorce, and marriage). A four-class trajectory solution provided the best fit for bereavement and marriage, while a three-class solution provided the best fit for divorce. Relevant covariates predicted trajectory class membership. The modal response across events was a relatively flat trajectory (i.e., no change). Nevertheless, some trajectories diverged sharply from the modal response. Despite the tendency to maintain preevent levels of SWB, there are multiple and often divergent trajectories in response to bereavement, divorce, and marriage, underscoring the essential role of individual differences.

  • Happy House: Spousal Weight and Individual Well-Being Article dans une revue:

    We use life satisfaction and Body Mass Index (BMI) information from three waves of the GSOEP to test for social interactions in BMI between spouses. Social interactions require that the cross-partial effect of partner’s weight and own weight in the utility function be positive. Using life satisfaction as a utility proxy, semi-parametric regressions show that the correlation between satisfaction and own BMI is initially positive, but turns negative after some threshold. Critically, this latter threshold increases with partner’s BMI when the individual is overweight. The negative well-being impact of own BMI is thus lower when the individual’s partner is heavier, which is consistent with social contagion effects in weight. However, this relationship may also reflect selection on the marriage market or omitted variables, and it is difficult to think of convincing instruments that would allow causality to be clearly established.

  • The Organisational Commitment of Workers in OECD Countries Article dans une revue:

    The degree to which workers identify with their firms, and how hard they are willing to work for them, would seem to be key variables for the understanding of both firm productivity and individual labour-market outcomes. This paper uses repeated cross-section ISSP data from 1997 and 2005 to consider three of measures of worker commitment. There are enormous cross-country differences in these commitment measures, which are difficult to explain using individual- or job-related characteristics. These patterns do, however, correlate with some country-level variables. While unemployment and inflation are both associated with lower commitment to an extent, economic and civil liberties are positively correlated with worker effort and pride in the firm.

  • La crise a-t-elle rendu l’épargnant plus prudent ? Article dans une revue:

    La crise économique et financière actuelle initiée en 2007 a connu différentes étapes marquées par plusieurs temps forts : crise dite des » subprimes » durant l’été 2007 après le dégonflement de la bulle immobilière américaine des années 2000, effondrement des marchés boursiers internationaux à l’automne 2008 faisant suite aux faillites de plusieurs établissements financiers américains, creusement des déficits publics dans de nombreux pays en 2009, les finances publiques ayant été fortement sollicitées par les gouvernements pour atténuer les effets de la récession. Comment l’épargnant a-t-il réagi à cette crise, face aux aléas boursiers, au durcissement des conditions de crédit et aux anticipations de baisse des prix des logements, aux perspectives économiques alarmistes relatives au pouvoir d’achat et au chômage ? Le taux d’épargne des fourmis françaises est resté à des niveaux élevés et a même augmenté en 2009. Parallèlement, la croissance de la consommation a fortement décru. Ailleurs en Europe, le taux d’épargne entre 2007 et 2009 a, de fait, augmenté presque partout, surtout dans les pays les plus touchés. Comment l’épargnant a-t-il » assimilé » ces évolutions ? En France plus particulièrement, la plupart des indicateurs macroéconomiques, mais également les enquêtes d’opinions montreraient que les comportements des ménages sont devenus plus prudents et plus prévoyants, la tendance étant de vouloir s’éloigner des investissements boursiers pour privilégier les placements plus sûrs, mais aussi de plus long terme.

  • Income and Happiness: Getting the Debate Straight Article dans une revue:

    Carol Graham (2011) asks a really good question: does higher income go with greater happiness and, if so, under which conditions? It is perhaps difficult to under-estimate how central the answer to this question is to Social Science. In particular, if well-being is indeed relative in income, then greater GDP per capita will not necessarily raise average well-being in an economy. Somewhat less feted, yet to my mind just as important, is the fact that income comparisons of the kind that Carol Graham is talking about have enormous implications for the analysis of individual well-being. In a nutshell, standard Economic analysis says that we will buy a good (or supply hours of work, or do whatever it is that we do) up until the marginal benefit from doing so, what we Economists call marginal utility, equals the marginal cost (the price of the good, or the value of the hour of leisure foregone). We typically think that such consumption is subject to the Law of decreasing marginal utility: the more of a good you have, the less you value having one more unit of it. This explains why we all, at some point, stop buying cars, eating ice cream, buying shirts, and earning income in general: the marginal utility from doing so just isn’t worth the marginal cost we have to pay. All well and good, but the kinds of comparisons that we are talking about here actually mount a serious challenge to this Law of decreasing marginal utility. If I compare to you, and you compare to me, then your buying an expensive car may increase my marginal utility of spending more on a new car. In general, my marginal utility of more income (or consumption) may rise with your income (or consumption). If this is the case, then your higher income will provide me with a greater incentive to increase my own income, which provides you with a greater incentive to increase your income, and so on ad infinitum. We are here then in the world of the rat race or the Arms Race. If I compare to you and you compare to me then the Law of decreasing marginal utility may well be weakened or indeed fail to hold at all. If so, we will all end up consuming too much, and not necessarily be any happier for it. Of course, the macroeconomic flipside of this is that greater income for all may not lead to greater happiness for all, as Dick Easterlin (1995) has pointed out. So these are very central questions indeed, from the points of view of understanding public policy and explaining individual consumption and labour-supply behaviours.1 They are well-worth studying, and indeed have led to what is now a considerable literature across the social sciences.

  • Do people always pay less than they say? Testbed laboratory experiments with IV and HG values Article dans une revue:

    Hypothetical bias is a long-standing issue in stated preference and contingent valuation studies – people tend to overstate their preferences when they do not experience the real monetary consequences of their decision. This view, however, has been challenged by recent evidence based on the elicitation of induced values (IV) in the lab and homegrown (HG) demand function from different countries. This paper uses an experimental design to assess the extent and relevance of hypothetical bias in demand elicitation exercises for both IV and HG values. For testbed purpose, we use a classic second-price auction to elicit preferences. Comparing the demand curve we elicit in both, hypothetical bias unambiguously (i) vanishes in an induced-value, private good context, and (ii) persists in homegrown values elicitation context. This suggests hypothetical bias in preference elicitation appears to be driven by « preference formation » rather than « preference elicitation ». In addition, companion treatments highlight two sources of the discrepancy observed in the HG setting: the hypothetical context leads bidders to underestimate the constraints imposed by their budget limitations, whereas the real context creates pressure leading them to bid « zero » to opt out from the elicitation mechanism. As a result, there is a need for a demand elicitation procedure that helps subjects take the valuation exercise sincerely, but without putting extra pressure on them.

  • Épargne et choix de portefeuille des ménages : approches micro et macroéconomiques Article dans une revue:

    La crise financière a rappelé le rôle majeur des comportements d’épargne et de placement des ménages dans les équilibres financiers. Par ailleurs, les investissements et l’allocation stratégique des actifs à long terme sont des enjeux clés pour les pays confrontés au vieillissement de leur population. La conférence internationale organisée par la Banque de France en mars 2011 a permis de dresser un état des lieux des évolutions des portefeuilles des ménages en Europe et aux États-Unis. Une attention particulière a été portée aux effets de la crise financière, à ses conséquences et aux défi s de long terme à relever pour les régulateurs, les banques centrales, les investisseurs institutionnels et financiers ainsi que les ménages eux-mêmes. Les travaux présentés font apparaître des effets contrastés de la crise selon les pays mais également au sein des populations. La perte moyenne en richesse nette a été massive, en particulier aux États-Unis, entre 2007 et 2009 et a concerné surtout les ménages les plus riches. Par ailleurs, certains ménages ont enregistré des gains sur la même période. Les pertes de richesse semblent avoir reflété essentiellement les évolutions des prix des actifs, les ménages ayant effectué peu de réallocations au sein de leurs portefeuilles. Les interventions ont également mis en avant le rôle majeur des actifs immobiliers dans le comportement d’épargne des ménages et dans la transmission des chocs de prix d’actifs. En outre, la question du financement à long terme a fait l’objet de plusieurs contributions. La question du rôle de la prévisibilité des rendements des actifs financiers pour l’allocation stratégique à long terme des actifs a été abordée. Enfin, face à l’accroissement de l’épargne placée sur les marchés financiers, conséquence de l’augmentation du niveau de vie, du développement des innovations financières et du renforcement des responsabilités individuelles pour le financement des besoins de long terme (retraite, santé, dépendance), les politiques d’éducation financière et l’information du public par les pouvoirs publics, mais aussi par les acteurs des marchés financiers, sont apparues comme essentielles.

Herein we explore how social psychology has affected one aspect of environmental economics: preference elicitation through survey work. We discuss social representation, social isolation, framing through cheap talk, and commitment theory through an oath.

  • La croissance du PIB rendra-t-elle les habitants des pays en développement plus heureux ? Article dans une revue:

    Ce texte s’interroge sur ce que les pays à bas revenu peuvent attendre de la croissance en termes de bien-être. Interprétant les données internationales disponibles, il observe que, conformément au paradoxe d’Easterlin, au sein d’un pays, les individus les plus riches se déclarent plus heureux ; les habitants des pays riches se déclarent plus heureux que ceux des pays pauvres ; mais sur le long terme, le bien-être moyen d’un pays ne semble pas s’élever avec le revenu national. En réalité, le lien dynamique entre croissance et bonheur reste vivement débattu ; la question est de savoir si le coefficient de corrélation entre les deux grandeurs peut être considéré comme négligeable ( » too small to matter « ). Les explications de la faible corrélation entre croissance du revenu et bien-être subjectif au cours du temps tiennent à la nature même de la croissance (par exemple les effets secondaires négatifs tels que la pollution) et à l’importance de phénomènes psychologiques tels que les comparaisons et l’adaptation. À cet égard, les données disponibles renferment deux enseignements importants : les comparaisons de revenu semblent bien affecter le bien-être subjectif, même dans les pays très pauvres ; cependant, l’adaptation est sans doute un phénomène plus spécifique aux pays riches. Nous pensons que les données disponibles ne permettent pas d’écarter l’idée que la croissance élèvera le bonheur dans les pays à faible revenu. D’une part, les analyses longitudinales internationales (qui conduisent à rejeter cette corrélation) reposent sur des mesures agrégées, qui sont moins fiables que les mesures individuelles (qui conduisent à valider cette corrélation). D’autre part, le développement est un processus qualitatif qui implique des décollages et des seuils. Or, les données révèlent que ces changements de régime s’accompagnent d’une évolution parallèle des mesures de satisfaction subjectives. Le cas des pays en transition est particulièrement remarquable à cet égard : les scores moyens de satisfaction dans la vie suivent étroitement l’évolution du PIB pendant les dix premières années environ du processus de transition, jusqu’à ce que le régime se stabilise. Si des mesures subjectives de bien-être étaient disponibles dans les pays à bas revenu, elles aideraient certainement à mesurer et suivre les différents stades et dimensions du processus de développement.

  • Schooling and smoking among the baby-boomers: an evaluation of the impact of educational expansion in France Article dans une revue:

    Post-war expansion of education in France transformed the distribution of schooling for the cohorts born between the 1940s and the 1970s. However, throughout this expansion the proportion with the highest levels of qualifications remained stable, providing a natural control group. We evaluate the impact of schooling on smoking, for the beneficiaries of the post-war expansion, by comparing changes in their outcomes across birth cohorts with changes within the control group. We uncover robust evidence that educational expansion contributed to a decline in smoking prevalence of 2.9 points of percentage for men and 3.2 points for women at the turn of the 21st century. Our results also suggest that the persistence of the schooling-smoking gradient is better explained by differences in the education-related opportunity costs of smoking than by differences in information about smoking dangers.

  • Public Employment and Political Pressure: The Case of French Hospitals Article dans une revue:

    This paper uses an unusual administrative dataset covering the universe of French hospitals to consider hospital employment: this is consistently higher in public hospitals than in not-for-profit (NFP) or private hospitals, even controlling for a number of measures of hospital output. NFP hospitals serve as a benchmark, being very similar to public hospitals, but without political influence on their hiring. Public-hospital employment is positively correlated with the local unemployment rate, whereas no such relationship is found in other hospitals. This is consistent with public hospitals providing employment in depressed areas. We appeal to the Political Science literature and calculate local political allegiance, using expert evaluations on various parties’ political positions and local election results. The relationship between public-hospital employment and local unemployment is stronger the more left-wing the local municipality. This latter result holds especially when electoral races are tight, consistent with a concern for re-election.

  • L’épargnant dans un monde en crise : ce qui a changé Ouvrages:

    La crise a affecté les comportements de l’épargnant : les ménages français se sont montrés en moyenne plus » prudents « , désirant épargner davantage dans des placements plus sûrs et à plus long terme, et limiter parallèlement leurs investissements risqués. Comment expliquer ce changement ? Les Français se sont-ils simplement adaptés au nouvel environnement économique et aux évolutions perçues dans leur situation personnelle : baisse anticipée des ressources ou des rendements d’actifs, exposition au risque plus élevée, etc. ? Ou bien la crise a-t-elle modifié la » psyché » même des individus, à savoir ici les préférences de l’épargnant en matière de risque et vis-à-vis du futur : manifeste-t-il une plus grande » aversion au risque » qu’hier ? En termes d’horizon décisionnel, l’épargnant est-il moins obnubilé par les échéances de court terme et plus soucieux de son avenir ? Bref, ses préférences sont-elles soumises aux aléas de la conjoncture économique et financière ? À cette question centrale, notre étude répond par la négative, concluant ainsi à la stabilité d’ensemble des préférences de nos compatriotes à l’égard du risque et du temps pendant la crise de 2008. Contrairement à une antienne à la mode, ce résultat qui peut surprendre révèle un épargnant » stoïque » dans la tourmente, pas plus averse au risque qu’auparavant.

  • Segregation, Entrepreneurship and Work Values: the Case of France Article dans une revue:

    This paper studies the interaction between labour market integration, « work values » and entrepreneurial capital inside minority communities. A simple model of labour market segmentation with ethnic capítal and endogenous transmission of cultural values inside a minority group is presented. It emphasizes the role of entrepreneurial capital as an important driver of labour market integration and as a promoter of meritocratic work values inside the community. The case immigrants in France is then empirically studied as an example. We show that the contrasted labour market outcomes and work values of immigrants from Maghreb versus Southern Europe are, statistically, totally explained away by their different levels of entrepreneurial capital.

  • Taxer les boissons sucrées pour lutter contre l’obésité ? Le point de vue de l’économie Article dans une revue:

    Depuis plusieurs décennies, on observe une forte progression de la consommation de boissons sucrées en France. Ceci s’explique notamment par la baisse du prix relatif de ces produits. Une augmentation des prix permettrait de freiner cette tendance. Une taxe sur les boissons sucrées peut atteindre cet objectif. Elle est en outre justifiée par la nécessité de limiter les coûts médicaux de l’obésité et du diabète, et par un souci de protection des consommateurs (en particulier les enfants). Une analyse économétrique des comportements d’achat des ménages révèle qu’une hausse de 1% du prix des boissons sucrées produirait une diminution de la consommation du même ordre (1%), sans effets de substitution délétères vers les boissons alcoolisées. En revanche, la taxe doit être très élevée pour avoir des effets significatifs en termes de santé publique.

  • Will GDP Growth Increase Happiness in Developing Countries? Communication dans un congrès:

    This paper asks what low-income countries can expect from growth in terms of happiness. It interprets the set of available international evidence pertaining to the relationship between income growth and subjective well-being. Conforming to the Easterlin paradox, higher income always correlates with higher happiness, except in one case: whether national income growth yields higher well-being is still hotly debated; essentially, the question is whether the correlation coefficient is “too small to matter”. The explanations for the small correlation between income growth and subjective well-being over time appeal to the nature of growth itself (e.g. negative side-effects such as pollution), and to the psychological importance of relative concerns and adaptation. The available evidence contains two important lessons: income comparisons do seem to affect subjective well-being even in very poor countries; however, adaptation may be more of a rich country phenomenon. Our stand is that the idea that growth will increase happiness in low-income countries cannot be rejected on the basis of the available evidence. First, cross-country time-series analyses are based on aggregate measures, which are less reliable than individual ones. Second, development is a qualitative process that involves take-offs and thresholds. Such regime changes are eye-visible through the lens of subjective satisfaction measures. The case of Transition countries is particularly impressive in this respect: average life satisfaction scores closely mirror changes in GDP for about the first ten years of the transition process, until the regime becomes more stable. If subjective measures of well-being were made available in low-income countries, they would certainly help measuring and monitoring the different stages and dimensions of the development process.

  • The emerging aversion to inequality Article dans une revue:

    This paper provides evidence of the changing attitudes to inequality during transition to the market in Poland. Using repeated cross-sections of the population, it identifies a structural break in the relationship between income inequality and satisfaction. Whereas in the first stage of the transition process, an increase in income inequality was interpreted by the population as a positive signal of wider opportunities, later in the transition period increased inequality became a factor in dissatisfaction with the country’s economic situation. This was accompanied by increasing public sentiment that the process of income distribution is flawed and corrupt.

  • Back to baseline in Britain: Adaptation in the BHPS Pré-publication, Document de travail:

    Ce papier utilise seize vagues de données de panel britanniques afin d’examiner le phénomène de l’accoutumance du bien-être aux événements majeurs de la vie. A l’exception du chômage, l’accoutumance aux autres événements (mariage, divorce, veuvage et naissance d’un enfant) est rapide et totale. Ces résultats britanniques sont très semblables aux résultats antérieurs obtenus sur données de panel allemandes. Le profil temporel du bien-être est très stable, que l’on mesure ce dernier par la « satisfaction dans la vie » ou par le stress psychologique. Le phénomène d’accoutumance semble avoir une portée générale, non spécifique aux données allemandes ou aux mesures simples de bien-être. Nous montrons également que le processus d’accoutumance n’est pas le même selon que les individus sont extravertis ou intravertis.

  • Boon or bane? Others’ unemployment, well-being and job insecurity Article dans une revue:

    The social norm of unemployment suggests that aggregate unemployment reduces the well-being of the employed, but has a far smaller effect on the unemployed. We use German panel data to reproduce this standard result, but then suggest that the appropriate distinction may not be between employment and unemployment, but rather between higher and lower levels of labour-market security, at least for men. Men with good job prospects, both employed and unemployed, are strongly negatively affected by regional unemployment. However, insecure employed men and poor-prospect unemployed men are less negatively, or even positively, affected. There is however no clear relationship for women. We analyse labour-market inequality and unemployment hysteresis in the light of our results.

Cette politique pourrait augmenter la vitesse de circulation du patrimoine entre les générations dans notre pays, qui se caractérise par un fort déséquilibre intergénérationnel, les patrimoines et les revenus des seniors ayant augmenté, alors que les conditions de vie des ménages des plus jeunes ont eu tendance à se détériorer.

    La qualité des relations entre individus est certainement une variable de première importance, non seulement en tant que dimension du bien-être individuel mais aussi en tant que déterminant du résultat de ces interactions. Ceci vaut notamment pour les relations sur le marché de travail, où l’on peut distinguer plusieurs types de relations: entre salariés, entre les salariés et leurs supérieurs, ou encore entre syndicats et entreprises. Ici nous nous concentrons sur la relation peut-être la plus centrale au sein de ce marché : celle entre le travailleur et l’entreprise, en faisant appel à des données relatives à 15 pays de l’OCDE.

  • Happy house: Spousal weight and individual well-being Pré-publication, Document de travail:

    Cet article propose de tester l’existence d’interactions sociales entre conjoints en matière d’indice de masse corporelle (IMC), en analysant l’effet de leurs deux IMC sur le bien-être de chacun. Pour ceci, trois vagues du German Socio-Economic Panel (GSOEP) sont utilisées. Des régressions semi-paramétriques montrent que l’IMC d’un individu est négativement corrélé à son bien-être au-delà d’un certain seuil. On remarque que ce seuil s’élève significativement lorsque l’IMC du conjoint augmente. Par conséquent, l’impact négatif de l’IMC individuel sur le bien-être est plus faible lorsque le conjoint est en surpoids ou obèse. Les incitations en matière de prise ou de perte de poids pourrait donc dépendre de l’IMC du partenaire, ce qui suggère l’existence d’effets d’interactions sociales. Cependant, des estimations par variables instrumentales montrent que cette relation n’est pas causale mais reflète plutôt l’existence d’effets de sélection sur le marché du mariage, avec la formation de couples homogames en matière de corpulence.

  • Who compares to whom? The anatomy of income comparisons in Europe Article dans une revue:

    This article provides unprecedented direct evidence from large-scale survey data on both the intensity (how much?) and direction (to whom?) of income comparisons. Income comparisons are considered to be at least somewhat important by three-quarters of Europeans. They are associated with both lower levels of subjective well-being and a greater demand for income redistribution. The rich compare less and are happier than average when they do, which latter is consistent with relative income theory. With respect to the direction of comparisons, colleagues are the most frequently-cited reference group. Those who compare to colleagues are happier than those who compare to other benchmarks.

    Ce manuel offre une présentation complète et approfondie des techniques économétriques les plus utilisées dans la pratique, allant du modèle linéaire et ses extensions aux techniques non-linéaires de traitement des données discrètes et censurées. Pour ce faire, les techniques présentées, et démontrées, sont systématiquement illustrées par des exemples sur données réelles ou la présentation de travaux de recherche consacrés à l’évaluation des politiques publiques (économie du travail, économie industrielle, etc). Un certain nombre de chapitres est en outre spécifiquement consacré aux outils d’évaluation des politiques publiques: estimateurs par différence, méthodes de score. Le parti pris de cet ouvrage est de mettre les problèmes d’identification au centre de la démarche économétrique. Un accent particulier est donc mis sur le lien entre la modélisation théorique, la spécification économétrique et la nature des données. L’ouvrage s’adresse ainsi non seulement à des étudiants de fin de premier cycle ou de deuxième cycle en économie, gestion ou école de commerce, mais également aux professionnels souhaitant approfondir leur connaissance des techniques mobilisées dans l’utilisation de l’économétrie à des fins d’évaluation.

  • Impact of acute health shocks on cigarette consumption: A combined DiD-matching strategy to address endogeneity issues in the French Gazel panel data Pré-publication, Document de travail:

    This paper investigates the relationship between an acute health shock, namely the first onset of an accident requiring medical care, and cigarette consumption, using the French Gazel panel data. To identify the causal effect of such shocks, we use a difference-in-differences approach combined with a propensity score. Results suggest that there is a significant effect running from the shock to the number of cigarettes smoked with impact duration of eight years after the shock. Individuals subject to such a shock smoke, on average, 2 cigarettes less (per week) than those not exposed to such a shock. Further, the findings show heterogeneous effects among smokers: heavy smokers are more likely to reduce tobacco consumption than occasional smokers.

  • Temperance in Stock Market Participation: Evidence from France Article dans une revue:

    We explore empirically whether earnings uncertainty and borrowing constraints deter households from the stock market, consistent with the predictions of theoretical studies of portfolio choice in the presence of uninsurable earnings. Since recent extensions highlight the importance of the correlation between earnings and financial risks, here we use a self-assessed proxy from the DELTA-TNS 2002 cross-sectional survey to empirically assess the impact. Although income risk does not affect the participation decision of households’ reporting a negative correlation, it does lower the participation of those who report a non-negative sign, consistent with economic theory predictions.

  • Compensating the dead? Yes we can! Pré-publication, Document de travail:

    Une mort précoce constitue, sans aucun doute, un dommage majeur. Cependant, la compensation des individus à vie courte est restée jusqu’à présent largement non explorée, principalement parce que cette compensation semble infaisable. En effet, les personnes à vie courte peuvent difficilement être identifiées ex ante, et ne peuvent plus être compensées ex post. Nous démontrons que, malgré les difficultés mentionnées ci-dessus, une compensation peut être réalisée, en encourageant la consommation au début du cycle de vie. Sur la base d’un modèle où la population présente des préférences hétérogènes et des longueurs de vie inégales, nous montrons qu’un critère social spécifique peut être dérivé à partir de principes intuitifs, et nous étudions la politique optimale correspondante sous divers contextes informationnels. Nous examinons enfin la robustesse de notre solution à diverses spécifications des préférences individuelles et à diverses politiques d’épargne.

  • Will GDP growth increase happiness in developing countries? Pré-publication, Document de travail:

    Ce texte s’interroge sur ce que les pays à faible revenu peuvent attendre de la croissance en termes de bien-être. Interprétant les données internationales disponibles, il observe que conformément au paradoxe d’Easterlin, plus le revenu est élevé, plus les individus se déclarent heureux, excepté dans un cas : le lien entre croissance de long terme du revenu national et augmentation du bien-être reste vivement débattu ; essentiellement, il s’agit de savoir si le coefficient de corrélation est trop faible pour être considéré comme significatif ( » too small to matter « ). Les explications de la faible corrélation entre croissance du revenu sur le long terme et bien-être subjectif tiennent à la nature même de la croissance (effets secondaires négatifs tels que la pollution) et à l’importance psychologique des phénomènes de comparaisons et d’adaptation. Les données disponibles contiennent deux enseignements importants : les comparaisons de revenu semblent bien affecter le bien-être subjectif, même dans les pays très pauvres ; cependant, l’adaptation est sans doute un phénomène plus spécifique aux pays riches. Nous pensons que les données disponibles ne permettent pas d’écarter l’idée que la croissance accroîtra le bonheur dans les pays à faible revenu. D’une part, les analyses longitudinales internationales reposent sur des mesures agrégées, qui sont moins fiables que les mesures individuelles. D’autre part, le développement est un processus qualitatif qui implique des décollages et des seuils. De tels changements de régime peuvent être suivis à la trace à travers les mesures de satisfaction subjectives. Le cas des pays en transition est particulièrement remarquable à cet égard : les scores moyens de satisfaction suivent étroitement l’évolution du PIB pendant les dix premières années du processus de transition, jusqu’à ce que le régime se stabilise. Si des mesures subjectives de bien-être étaient disponibles dans les pays à bas revenu, elles aideraient certainement à évaluer les différents stades et dimensions du processus de développement des pays à faible revenu.

  • Where Should We Live? Article dans une revue:

    One of the central topics in recent empirical work on subjective well-being is that of comparisons to a reference group, over a variety of domains of economic and social life. One such reference group is neighbours. Any resulting spatial spillovers that are identified have potential implications for the welfare-maximising degree of spatial segregation. In this paper, we summarise some recent findings with respect to geographical comparisons of income, unemployment, health and religion, and present some new results regarding spatial spillovers in marriage. The resulting predictions regarding spatial segregation differ sharply according to the domain under consideration. While work in this area remains very preliminary, subjective well-being data may well help to both identify spillovers from neighbours, and inform about individuals’ location decisions.

  • Work, jobs and well-being across the Millennium Pré-publication, Document de travail:

    Nous faisons appel à trois vagues de données de l’ISSP (1989, 1997 et 2005) afin de mesurer l’évolution de la qualité de l’emploi. En premier lieu nous soulignons que le chômage demeure l’une des causes les plus importantes des faibles niveaux de bien-être. Ensuite, l’importance relative accordée par les individus aux divers aspects du travail est restée plutôt stable dans le temps, bien qu’on note une certaine tendance à accorder plus de poids aux domaines les plus « sociaux » : les postes jugés utiles, et qui permettent d’aider les autres. Le principal résultat de notre analyse est que la qualité de l’emploi a rebondi entre 1997 et 2005, après avoir chuté dans la première moitié des années 90. Selon certaines estimations, la satisfaction au travail est plus élevée en 2005 qu’en 1989. En dernier lieu, le pourcentage de travailleurs indépendants a légèrement diminué selon les données de l’ISSP; néanmoins, le nombre de travailleurs qui expriment une préférence pour le travail indépendant est systématiquement trois ou quatre fois plus important que le nombre de travailleurs effectivement indépendants. Puisque les indépendants sont plus satisfaits de leur travail que les salariés, une interprétation de ces faits est que les barrières à l’entrée au travail indépendant sont devenues plus élevées.

Les individus plus religieux sont aussi plus satisfaits. Mais la religion d’autrui compte aussi: la satisfaction individuelle est corrélée positivement avec la religiosité moyenne dans la région. Cette relation tient aussi bien pour les individus religieux que pour les individus non-religieux. Nous trouvons également que la satisfaction des Protestants et des Catholiques est plus élevée quand ils habitent dans une région où leur religion est dominante, et que les Protestants sont plus satisfaits dans les régions où les Catholiques sont dominants Les retombées positives de la religion d’autrui ne s’expliquent pas par le capital social, le crime ou la confiance en autrui.

  • Food price policies and the distribution of body mass index: Theory and empirical evidence from France Pré-publication, Document de travail:

    Cette recherche examine l’effet des prix de 23 catégories de produits alimentaires sur la distribution de l’indice de masse corporelle (IMC) de la population adulte française, à partir de données d’achats pour l’alimentation à domicile (enquête TS-WorldPanel). A l’aide d’un modèle de choix rationnel intégrant des hypothèses physiologiques sur la dynamique du poids corporel, on montre que le niveau d’activité physique (NAP) de l’individu module les effets des prix sur son IMC. L’identification de ces derniers requiert alors une forme d’indépendance statistique entre le NAP, qui n’est pas observé, et les variables explicatives de l’IMC, en particulier le revenu. Sous cette condition, il est possible de simuler l’impact de diverses politiques de prix sur la distribution inconditionnelle de l’IMC dans la population. On trouve, en particulier, qu’une augmentation de 10% du prix des boissons sucrées non alcoolisées, des protéines panées, des desserts, des pâtisseries, des produits de grignotage et des plats préparés, associée à une diminution de 10% du prix des fruits et légumes au naturel réduirait la prévalence du surpoids et de l’obésité de 24% et de 33% respectivement, pour une économie en dépenses de soins qui représenterait 1,39% du total des dépenses médicales en 2004.

    Cet article étudie l’effet des prix de vingt-trois catégories d’aliments sur la distribution de l’indice de masse corporelle (imc) de la population adulte française, à l’aide des données de scanner du panel de ménages tns-WorldPanel. Les résultats de régressions quantiles indiquent que l’imc des femmes à risque pour le surpoids ou l’obésité a une élasticité négative aux prix des fromages, des huiles, des pâtisseries et desserts, et des plats préparés. L’imc des hommes à risque pour le surpoids a une élasticité négative aux prix des boissons non alcoolisées (hors eau) et des plats préparés. Si des politiques de prix visant simultanément plusieurs catégories de produits pourraient avoir des effets significatifs, nos résultats doivent donc être utilisés avec la plus grande prudence. En effet, l’inobservabilité de variables importantes, comme l’activité physique des individus, pourrait biaiser les résultats.

  • Job satisfaction and co-worker wages: status or signal? Article dans une revue:

    We use matched employer-employee panel data to show that individual job satisfaction is higher when other workers in the same establishment are better-paid. This runs counter to substantial existing evidence of income comparisons in subjective well-being. We argue that the difference hinges on the nature of the reference group. Here we use co-workers. Their earnings not only induce jealousy but also provide a signal about the worker’s own future earnings. In our data, this positive future earnings signal outweighs any negative status effect. This phenomenon is stronger for men and in the private sector but weaker for those nearer retirement.

  • My Father was right”: The transmission of values between generations Pré-publication, Document de travail:

    En France, l’influence des comportements patrimoniaux des parents sur celui de leurs enfants a souvent été mise en évidence. Comment expliquer alors ce « poids d’Anchise » ? Dans cet article, nous utilisons une enquête originale française et unique initiée par le Delta et TNS-Sofres en 2002 dans laquelle nous disposons à la fois d’informations patrimoniales et subjectives pour deux générations. En rapprochant les préférences vis-à-vis de l’épargne des parents et des enfants concernant leurs attitudes face au risque et à l’avenir, nous obtenons des corrélations intergénérationnelles significatives, de l’ordre de 0,25 qui ne justifient cependant pas une similarité parfaite. Par ailleurs, l’élasticité de la richesse des enfants par rapport à celle de leurs parents se situe autour de 0,22. Cette mesure est corrigée des effets d’âge et concerne les patrimoines de deux générations coexistantes, c’est-à-dire avant que le gros des transferts intergénérationnels ait eu lieu. Plus de 40% de cette élasticité peut être expliqué (directement ou indirectement) par les niveaux de revenu permanent des deux générations. Les niveaux d’éducation et les préférences y contribuent chacun pour un cinquième, les transferts intergénérationnels déjà effectués pour 13%. La contribution des goûts de l’épargnant est encore de 13% lorsque l’on tient compte également des revenus permanents. Même si elle n’est pas la seule, la transmission des préférences joue donc un rôle non négligeable dans la transmission des inégalités de patrimoine.

  • Job security and job protection Article dans une revue:

    We construct indicators of the perception of job security for various job types in 12 European countries using individual data from the European Community Household Panel (ECHP). We then consider the relation between reported job security and OECD summary measures of Employment Protection Legislation (EPL) strictness on the one hand, and Unemployment Insurance Benefit (UIB) generosity on the other. We explicitly recognize that insecure types may attempt to self-select into more secure jobs. After modeling this selection, we find that workers feel most secure in permanent public sector jobs, least secure in temporary jobs, with permanent private sector jobs occupying an intermediate position. We also find that perceived job security in both permanent private and temporary jobs is positively correlated with UIB generosity, while the relationship with EPL strictness is negative: workers feel less secure in countries where jobs are more protected. These correlations are absent for permanent public jobs, suggesting that such jobs are perceived to be by and large insulated from labor market fluctuations.

  • Economic satisfaction and income rank in small neighbourhoods Article dans une revue:

    We contribute to the literature on well-being and comparisons by appealing to new Danish data dividing the country up into around 9,000 small neighbourhoods. Administrative data provides us with the income of every person in each of these neighbourhoods. This income information is matched to demographic and economic satisfaction variables from eight years of Danish ECHP data. Panel regression analysis shows that, conditional on own household income, respondents report higher satisfaction levels when their neighbours are richer. However, individuals are rank-sensitive: Conditional on one’s own income and neighbourhood median income, respondents are more satisfied as their percentile neighbourhood ranking improves. A ten percentage point rise in rank (i.e., from 40th to 20th position in a 200-household cell) is worth 0.11 on a 1-6 scale, which is a large marginal effect in satisfaction terms.

  • Measuring well-being across Europe: description of the ESS well-being module and preliminary findings Article dans une revue:

    It has become customary to judge the success of a society through the use of objective indicators, predominantly economic and social ones. Yet in most developed nations, increases in income, education and health have arguably not produced comparable increases in happiness or life satisfaction. While much has been learned from the introduction of subjective measures of global happiness or life satisfaction into surveys, significant recent progress in the development of high-quality subjective measures of personal and social well-being has not been fully exploited. This article describes the development of a set of well-being indicators which were included in Round 3 of the European Social Survey. This Well-being Module seeks to evaluate the success of European countries in promoting the personal and social well-being of their citizens. In addition to providing a better understanding of domain-specific measures, such as those relating to family, work and income, the design of the Well-being Module recognises that advancement in the field requires us to look beyond measures which focus on how people feel (happiness, pleasure, satisfaction) to measures which are more concerned with how well they function. This also shifts the emphasis from relatively transient states of well-being to measures of more sustainable well-being. The ESS Well-being Module represents one of the first systematic attempts to create a set of policy-relevant national well-being accounts.

  • Immigration and natives’ attitudes towards redistribution: evidence from the european social survey Article dans une revue:

    Does immigration reduce natives’ support for the welfare state? Evidence from the European Social Survey (2002/2003) suggests a more qualified relation. For Europe as a whole, there is only weak evidence of a negative association between the perceived presence of immigrants and natives’ support for the welfare state. However, this weak average relationship masks considerable heterogeneity across countries. We distinguish two channels through which immigration could affect natives’ support for the welfare state: a pure dislike of immigrants and concerns about the economic consequences of immigration. We find that natives who hold both negative views react much more negatively to a given perceived share of immigrants than natives who hold neither view. However, there is no clear pattern concerning the relative importance of the two channels. Finally, we find that natives who hold either of these negative views of immigrants tend to be less supportive of the welfare state independently of the perceived presence of immigrants.

  • Valuing jobs via retirement: European evidence Pré-publication, Document de travail:

    Si la valeur du travail relativement au chômage a été au centre de nombre de travaux, il n’en va pas de même pour la valeur du travail par rapport à la retraite. Nous exploitons deux bases de données de panel européennes afin de montrer dans un premier temps que le bien-être psychologique (mesuré par les indices EURO-D et GHQ) des individus ne varie quasiment pas lorsque ceux-ci prennent leur retraite. Cette variation est toutefois très hétérogène selon le type d’emploi occupé avant la retraite d’un individu à un autre. Certains gagnent à s’arrêter de travailler tandis que d’autres voient leur bien-être se dégrader considérablement à la retraite et préféreraient donc probablement continuer à travailler. Nous pensons que les résultats de ces analyses peuvent être utiles aux politiques visant à encourager la participation des seniors au marché du travail.

  • Who compares to whom? The anatomy of income comparisons in Europe Pré-publication, Document de travail:

    Cet article repose sur une information inédite et « directe » concernant les comparaisons de revenu et les groupes de référence auxquels les individus se comparent. Une majorité d’européens considèrent les comparaisons au revenu d’autrui comme un élément important de leur satisfaction vis-à-vis de leur propre revenu. Les comparaisons réduisent leur bien-être subjectif et suscitent une demande de redistribution des revenus. Le groupe de référence le plus répandu est constitué par les collègues de travail. Les comparaisons à ce groupe sont également les moins nocives pour le bien-être. Les comparaisons aux amis sont ainsi à la fois plus rares et beaucoup plus délétères. Cet ensemble d’observations est compatible avec des effets informationnels à la Hirschman, dans la mesure où les groupes de références professionnels sont ceux qui sont les plus susceptibles de constituer non seulement une aune de comparaisons, mais aussi une source d’information sur les perspectives offertes à un individu.

  • Peut-on dire que les Français sont malheureux ? Pré-publication, Document de travail:

    Les Français se déclarent moins heureux que la plupart des Européens. Yann Algan et Pierre Cahuc (2007) ont suggéré que cette insatisfaction prenait sa source dans l’absence de confiance qu’ils s’accordent les uns aux autres, ainsi qu’aux institutions de leur pays. Sans vouloir exclure cette interprétation, il est important de noter que des enquêtes de plus en plus nombreuses montrent que l’insatisfaction des Français revêt une grande généralité, au-delà de la question de la confiance ; elle culmine en ce qui concerne le monde du travail. Il apparaît également que la France ne constitue pas un cas isolé mais que sa position est partagée par d’autres pays tels que l’Italie, l’Allemagne et le Portugal. S’agit-il d’un artefact lié à la manière de répondre à ce type de questions ou peut-on identifier des domaines dont lesquels les Français sont particulièrement insatisfaits ? Cet article apporte des éléments de réponse à l’aide d’une enquête européenne réalisée en vue de ces questions.

  • Analyse économique de la criminalité Chapitre d’ouvrage:

    L’ouvrage propose une introduction aux méthodes et problématiques du courant Law & Economics. Né aux États-Unis au début des années 1960, celui-ci a trouvé son origine dans les travaux d’économistes de l’Université de Chicago qui tentaient d’appliquer les instruments usuels de l’analyse économique à des domaines jusqu’alors relativement peu explorés par les économistes, comme les choix constitutionnels, les droits de propriété, les accidents ou les activités « illégales ». Depuis lors, les questions abordées se sont très largement diversifiées, touchant à tous les domaines du droit. Méthodologiquement, le courant s’est enrichi des avancées de la discipline économique, intégrant les apports de la théorie des jeux, de l’économétrie ou de l’économie expérimentale, dans un souci de dialogue constant entre économistes et juristes. L’ouvrage rend compte de ces développements en réalisant un compromis entre le manuel et le handbook. Il fournit tout d’abord une introduction aux modèles de référence explorant trois grandes matières juridiques (la responsabilité, les conflits, la criminalité), et propose ensuite des synthèses de littérature sur des questions plus spécifiques débattues dans la période récente (les relations entre finance et droit de l’entreprise, l’économie du droit du divorce ou du droit du travail, l’apport de la méthode expérimentale) ou sur des problématiques plus exploratoires (la question de la production des normes juridiques). Les abondantes références bibliographiques permettent de revenir aux sources d’un domaine encore récent et/ou de s’orienter vers des questions qui n’ont pas été abordées ici.

  • Welfare, Well-Being and Immigration in Europe: Evidence from the European Social Survey N°spécial de revue/special issue:

    Does immigration reduce natives’ support for the welfare state? Evidence from the European Social Survey (2002/2003) suggests a more qualified relation. For Europe as a whole, there is only weak evidence of a negative association between the perceived presence of immigrants and natives’ support for the welfare state. However, this weak average relationship masks considerable heterogeneity across countries. We distinguish two channels through which immigration could affect natives’ support for the welfare state: a pure dislike of immigrants and concerns about the economic consequences of immigration. We find that natives who hold both negative views react much more negatively to a given perceived share of immigrants than natives who hold neither view. However, there is no clear pattern concerning the relative importance of the two channels. Finally, we find that natives who hold either of these negative views of immigrants tend to be less supportive of the welfare state independently of the perceived presence of immigrants.

Nous commençons par recenser les travaux qui évaluent la pertinence empirique du monde sans friction décrit par le théorème de Coase, dans lequel l’environnement juridique se limite à allouer les droits de propriété. Nous nous intéresserons ensuite à l’analyse expérimentale des règles de droit qui régissent les règles de concurrence. Les deux derniers thèmes retenus sont consacrés à des situations de déviation à l’égard du droit ou des engagements pris: les dispositions juridiques de résolution des conflits ainsi que les procédures de négociation, puis les comportements criminels et leur répression.

  • Relative income, happiness, and utility: An explanation for the Easterlin paradox and other puzzles Article dans une revue:

    The well-known Easterlin paradox points out that average happiness has remained constant over time despite sharp rises in GNP per head. At the same time, a micro literature has typically found positive correlations between individual income and individual measures of subjective well-being. This paper suggests that these two findings are consistent with the presence of relative income terms in the utility function. Income may be evaluated relative to others (social comparison) or to oneself in the past (habituation). We review the evidence on relative income from the subjective well-being literature. We also discuss the relation (or not) between happiness and utility, and discuss some nonhappiness research (behavioral, experimental, neurological) related to income comparisons. We last consider how relative income in the utility function can affect economic models of behavior in the domains of consumption, investment, economic growth, savings, taxation, labor supply, wages, and migration.

  • Does Resorting to Online Dispute Resolution Promote Agreements ? Experimental Evidence Article dans une revue:

    This paper presents an experiment performed to test the properties of an innovative bargaining mechanism (called automated negotiation) used to resolve disputes arising from Internet-based transactions. The main result shows that the settlement rule tends to chill bargaining as it creates incentives for individuals to misrepresent their true valuations, which implies that automated negotiation is not able to promote agreements. However, this perverse effect depends strongly on the conflict situation. When the threat that a disagreement occurs is more credible, the strategic effect is reduced since defendants are more interested in maximizing the efficiency of a settlement than their own expected profit. The implications of these results are then used to discuss the potential role of public regulation and reputation mechanisms in Cyberspace.

The findings are as follows: (i) Such an experiment is feasible, and very well accepted by voters. (ii) The principle of approval voting is easily understood and accepted. (iii) Within the observed political context, compared to the official first-round vote, approval voting modifies the overall ranking of candidates. (iv) The candidates Le Pen and Chirac, more than the others, were able to convert approval votes into official first-round votes.

  • Never the same after the first time: The satisfaction of the second-generation self-employed Pré-publication, Document de travail:

    Plusieurs études ont montré que les travailleurs indépendants sont généralement plus satisfaits que les salariés. Dans cette étude, nous contribuons à la littérature existante de deux façons. Premièrement, nous mobilisons les données françaises de l’enquête ECHP et les données anglaises du BHPS afin d’étudier en détail les différences de satisfaction selon les différents domaines de satisfaction (condition de travail, revenu, sécurité de l’emploi, durée du travail). Nos résultats montrent, en contrôlant par la profession, que les travailleurs indépendants sont généralement plus satisfaits que les salariés de leurs conditions de travail et de leur salaire. Ils sont, au contraire, moins satisfaits que les salariés concernant la sécurité de l’emploi. Deuxièmement, nous étudions les différences de satisfaction entre les travailleurs indépendants de première et seconde générations (ceux dont les parents sont également travailleurs indépendants). Nos résultats indiquent que les travailleurs indépendants de première génération sont généralement plus satisfaits que ceux de seconde génération. Une première explication réside dans le fait que les transferts intergénérationnels permettent de relâcher la contrainte de participation au travail indépendant. Une deuxième explication repose sur le postulat selon lequel la satisfaction est relative et que les individus comparent leur situation sur le marché du travail à celle de leurs parents.

  • Keynesian hospitals? Public employment and political pressure Pré-publication, Document de travail:

    En France, les hôpitaux publics ont une densité de personnel hospitalier plus élevée que celui des établissements privés (à but lucratif ou participant au service public – PSPH). Ce constat reste vrai après contrôle de l’activité hospitalière. Parallèlement, le nombre d’employés dans les établissements publics est positivement corrélé au taux de chômage local. Cette corrélation n’apparaît plus lorsque l’on s’intéresse aux établissements privés. L’objet de ce papier est d’étudier le sens du lien entre la densité du personnel hospitalier et les facteurs sociaux. A partir d’indicateurs obtenus en sciences politiques, nous étudions l’impact du positionnement social des partis politiques et des résultats aux élections locales sur le nombre d’employés dans les établissements de santé. Il apparaît que la relation entre la densité de personnel des établissements publics et le taux de chômage local est d’autant plus fort que la municipalité élue est de Gauche. Ce résultat est accentué lorsque l’issue de l’élection fut incertaine (un second tour serré).

  • Mon père avait raison” : la transmission des valeurs entre les générations Pré-publication, Document de travail:

    En France, l’influence des comportements patrimoniaux des parents sur celui de leurs enfants a souvent été mise en évidence. Comment expliquer alors ce « poids d’Anchise » ? Dans cet article, nous utilisons une enquête originale française et unique initiée par le Delta et TNS-Sofres en 2002 dans laquelle nous disposons à la fois d’informations patrimoniales et subjectives pour deux générations. En rapprochant les préférences vis-à-vis de l’épargne des parents et des enfants concernant leurs attitudes face au risque et à l’avenir, nous obtenons des corrélations intergénérationnelles significatives, de l’ordre de 0,25 qui ne justifient cependant pas une similarité parfaite. Par ailleurs, l’élasticité de la richesse des enfants par rapport à celle de leurs parents se situe autour de 0,22. Cette mesure est corrigée des effets d’âge et concerne les patrimoines de deux générations coexistantes, c’est-à-dire avant que le gros des transferts intergénérationnels ait eu lieu. Plus de 40% de cette élasticité peut être expliqué (directement ou indirectement) par les niveaux de revenu permanent des deux générations. Les niveaux d’éducation et les préférences y contribuent chacun pour un cinquième, les transferts intergénérationnels déjà effectués pour 13%. La contribution des goûts de l’épargnant est encore de 13% lorsque l’on tient compte également des revenus permanents. Même si elle n’est pas la seule, la transmission des préférences joue donc un rôle non négligeable dans la transmission des inégalités de patrimoine.

  • Lags and leads in life satisfaction: A test of the baseline hypothesis Article dans une revue:

    We look for evidence of habituation in twenty waves of German panel data: do individuals tend to return to some baseline level of well-being after life and labour market events? Although the strongest life satisfaction effect is often at the time of the event, we find significant lag and lead effects. We cannot reject the hypothesis of complete adaptation to marriage, divorce, widowhood, birth of child and layoff. However, there is little evidence of adaptation to unemployment for men. Men are somewhat more affected by labour market events (unemployment and layoffs) than are women but in general the patterns of anticipation and adaptation are remarkably similar by sex.

  • Immigration and natives’ attitudes towards the welfare state: Evidence from the European Social Survey Pré-publication, Document de travail:

    Est-il vrai que l’immigration réduit l’adhésion des citoyens à la redistribution des revenus ? En nous appuyant sur les données de l’enquête European Social Survey (2002/2003), nous observons une association négative mais faible entre le poids des immigrés perçu par les « natifs » et le soutien de ces derniers à l’Etat-providence. En revanche, la demande de redistribution semble bien dépendre des attitudes vis-à-vis des immigrés. Nous distinguons deux canaux reliant potentiellement ces dispositions : d’une part un « goût » éventuel pour la mixité et d’autre part des motifs purement économiques (réciprocité et intérêt personnel). Chacun de ces canaux réduit la demande de redistribution des individus. Chez les individus qui expriment à la fois une aversion pour le mélange avec les immigrés et une inquiétude concernant les conséquences économiques de l’immigration, la demande de redistribution est particulièrement sensible à la présence des immigrés telle qu’ils la perçoivent subjectivement.

  • Les Français sont-ils prudents ? Patrimoine et risque sur le marché du travail Article dans une revue:

    Constituer une réserve contre les circonstances imprévues « , voilà comment Keynes (1936) commençait sa liste des » huit motifs principaux, ou raisons de caractère subjectif, qui poussent les individus à s’abstenir de dépenser leur revenu « . Cette épargne de précaution — notamment contre les aléas des ressources futures — modélisée trente ans plus tard par Leland (1968), Sandmo (1970) ou Drèze et Modigliani (1972) et renouvelée par Kimball (1993), a toujours été une des motivations principales avancées pour expliquer l’accumulation du patrimoine, à côté de la préparation de la retraite et de la transmission intergénérationnelle. La quantification de la prudence des épargnants face au risque de revenu futur a fait l’objet d’une abondante littérature empirique, cependant loin d’aboutir à un consensus. Pour résumer, d’un côté les méthodes de simulation calibrant (sur données réelles de revenu) des modèles théoriques de cycle de vie pour expliquer l’épargne des ménages aboutissent à un chiffre de l’ordre de 50 % pour la part du patrimoine de précaution dans le total, alors que de l’autre, les travaux économétriques proposent une fourchette allant de 1 % à 20 %. Ces dernières évaluations semblent plus raisonnables puisqu’en d’autres termes, quantifier le motif de précaution au-delà de 50 % signifierait que la moitié des inégalités de patrimoine pourrait être expliquée uniquement par la prudence des épargnants. L’objectif de notre travail est de quantifier le motif de précaution des épargnants français face à des risques portant sur leurs revenus futurs à partir des données de l’enquête Patrimoine 2004 de l’Insee. Les mesures de ces aléas sont subjectives, directement anticipées par un membre du ménage pour les cinq années futures. Elles concernent soit la probabilité de perdre son emploi, soit les évolutions possibles du revenu. Au final, le motif d’épargne de précaution apparaît limité chez les Français.

  • How populist democracy promotes market liberalization Pré-publication, Document de travail:

    A l’aide d’une enquête récente couvrant 28 pays anciennement socialistes, nous mettons en évidence une relation de causalité entre démocratie et adhésion au marché. Notre stratégie d’identification repose sur la restriction de l’échantillon aux habitants des zones-frontières intégrées. Ces derniers partagent en effet le même héritage historique en termes de valeurs et d’attitudes vis-à-vis du marché et de la démocratie, ainsi que la même expérience concrète du marché. Le mécanisme proposé repose sur le fait que les agents, hostiles à l’inégalité engendrée par la transition vers le marché, acceptent l’approfondissement des réformes à condition de pouvoir compter sur le gouvernement pour corriger en partie les inégalités de revenus. La démocratie joue ici le rô le d’un mécanisme d’engagement de l’Etat en faveur d’une intervention sur la répartition des revenus. Cependant, la démocratie formelle n’est pas suffisante pour garantir la crédibilité du gouvernement aux yeux de ces agents. La qualité des institutions, mesurée par la confiance des agents dans le gouvernement, est une condition nécessaire à leur adhésion au marché.

  • Measuring well-being across Europe: Description of the ESS Well-being Module and preliminary findings Pré-publication, Document de travail:

    Il est courant de juger le succès d’ une société par le biais d’indicateurs objectifs, le plus souvent économiques ou sociaux. Cependant, le progrès en termes d’éducation, de santé ou de revenu n’a peut-être pas produit l’augmentation de bien-être que l’on aurait espéré. Bien que l’analyse de la satisfaction dans la vie ou du bonheur soit très instructive, il serait sans doute utile d’introduire d’autres mesures de bien-être dans le débat. Cet article décrit le développement d’un volet d’indicateurs de bien-être inclus dans la vague 3 du European Social Survey (ESS). Ces questions tentent de mesurer le bien-être personnel et social des individus dans les pays européens. L’intérêt de ce volet est double. Dans un premier temps, il fournit des mesures de bien-être dans les domaines précis, tels que la famille, le travail et la santé. Ensuite, il dépasse la simple mesure hédonique (bonheur, plaisir, satisfaction) en proposant des mesures de la manière dont les individus vivent leur vie (functioning). En tant que tel, les indices qui en résultent concernent plutôt le bien-être soutenable que des états transitoires. Le volet de questions de l’ESS est l’une des premières tentatives de créer un ensemble de mesures de bien-être au niveau individuel et national.

  • Ambition and jealousy: Income interactions in the ‘Old Europe versus the ‘New’ Europe and the United States Article dans une revue:

    Using individual-level data from a large number of countries, this paper examines how self-reported subjective well-being depends on own income and reference income, where reference income is defined as the income of one’s professional peers. It uncovers a divide between ‘old’–low-mobility–European countries on the one hand, and ‘new’ European post-Transition countries and the United States on the other. The relative importance of comparisons (‘jealousy’) versus information (‘ambition’) seems to depend on the degree of mobility and uncertainty in the considered countries.

  • Direct evidence on income comparisons and their welfare effects Pré-publication, Document de travail:

    Exploitant une enquête conduite en 2006 par la BERD dans 28 pays en transition (LITS), cet article tente de mettre en évidence l’importance des comparaisons de revenu et leur effet sur le bien-être subjectif des agents. Il évalue également le poids relatif de différentes aunes de comparaison. Il apparaît que les comparaisons dans le temps sont plus importantes que les comparaisons statiques. Les catégories de références internes sont plus importantes que les groupes de référence externes. Enfin, les comparaisons à des groupes précis ont davantage d’impact que le rang subjectif d’un individu au sein de la hiérarchie sociale. L’effet le plus remarquable en terme de bien-être provient de la détérioration du niveau de vie des enquêtés par rapport au passé, ainsi que du fait de connaître une évolution moins favorable que d’anciens camarades de classes ou d’anciens collègues. Une interprétation possible est que les comparaisons sont d’autant plus puissantes qu’elles sont interprétées par les agents en termes d’occasions saisies ou manquées.

Ces données correspondent à une partition du pays en 9000 petites zones géographiques. Les sources administratives nous renseignent sur le revenu de chaque individu au sein de ces zones de voisinage. Nous apparions cette information régionale à des données individuelles comportant des variables de satisfaction économique ainsi que des variables socio-démographiques : les huit vagues de l’ECHP au Danemark. Dans les régressions de panel, les individus font état d’un niveau de satisfaction plus élevé quand leurs voisins sont plus riches. Cependant, ils sont sensibles au rang. Contrôlant pour le revenu individuel et le revenu du voisinage, les individus dont le rang dans le voisinage est plus élevé sont plus satisfaits. Une augmentation de rang de dix points (par exemple, de la 40ème à la 20ème position dans un voisinage de 200 personnes) induit une augmentation de satisfaction de 0,11 points sur une échelle de 1 à 6.

    Monitoring is typically included in economic models of crime thanks to a probability of detection, constant across individuals. We build on recent results in psychology to argue that comparative optimism deeply affects this standard relation. To this matter, we introduce an experiment involving proper incentives that allow a measurement of optimism bias. Our experiments support the relevance of so-called comparative optimism in decision under risk. In the context of illegal activities, our results provide a guide into costless devices to undermine fraud, through well-designed information campaigns.

En revanche, l’effet du chômage local sur le bien-être de ceux qui occupent des emplois précaires et des chômeurs à l’avenir plus sombre est moins négatif, voire positif.

  • Physicians’ Multitasking and Incentives: Empirical Evidence from a Natural Experiment Article dans une revue:

    We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation system, combining a xed per diem with a partial (relative to the traditional fee-for-service system) fee for services provided. We combine panel survey and administrative data on Quebec physicians to evaluate the impact of this change in incentives on their practice choices. We highlight the dierentiated impact of incentives on various dimensions of physician behaviour by considering a wide range of labour supply variables: time spent on seeing patients, time devoted to teaching, administrative tasks or research, as well as the volume of clinical services and average time per clinical service. Our results show that, on average, the reform induced physicians who changed from FFS to MC to reduce their volume of (billable) services by 6.15% and to reduce their hours of work spent on seeing patients by 2.57%. Their average time spent per service increased by 3.58%, suggesting a potential quality-quantity substitution. Also the reform induced these physicians to increase their time spent on teaching and administrative duties (tasks not remunerated under the fee-for-service system) by 7.9%.

  • Policy Analysis in the health-services market: accounting for quality and quantity Article dans une revue:

    We provide a theoretical and empirical framework for evaluating the eects of policy reforms on physician labor supply. We argue that any policy evaluation must account for both the quality and the quantity of services provided. The introduction of quality into the analysis has implications for both the theoretical and empirical analysis of labor supply, and consequently policy evaluation. In particular, endogenous quality choices introduce non- linearities into the budget constraint since the marginal return to an hour of work depends on the quality of services provided. We illustrate by considering a particular example: the recent reform in compensation contracts for specialist physicians in the province of Quebec (Canada). Prior to 1999, most Quebec specialist physicians were paid fee-for-service con- tracts; they received a piece rate for each clinical service provided. In 1999, the government introduced a mixed remuneration system, under which physicians received a base (half-daily or daily) wage, independent of services provided, and a reduced fee-for-service. Moreover, the government allowed physicians to choose their contract. We derive theoretical results for the eect of the reform on the quantity and quality of services supplied by analyzing « local » prices and virtual income. We propose discretizing the choice set as an empirical approach to policy evaluation in the presence of non-linear budget constraints.

  • Job satisfaction and co-worker wages: Status or signal? Pré-publication, Document de travail:

    Ce papier utilise des données appariées entre salariés et entreprises afin de montrer que les individus font état de niveaux de satisfaction au travail plus élevés quand les autres salariés de la même entreprise sont mieux payés. Ce résultat va à l’encontre d’une littérature importante sur le bien-être individuel qui a plutôt mis en exergue des comparaisons de revenu. Nous suggérons que la différence entre ces résultats provient de la nature du groupe de référence. Ici nous considérons des collègues au travail, dont le salaire peut induire un sentiment de jalousie, mais également informer l’individu sur son salaire futur potentiel. Le fait que le coefficient estimé sur le salaire des collègues soit positif montre que l’effet positif du signal l’emporte sur l’effet négatif du statut. Ce phénomène se trouve surtout pour les hommes et dans le secteur privé.

  • Measuring health polarization with self-assessed health data Article dans une revue:

    This paper proposes an axiomatic foundation for new measures of polarization that can be applied to ordinal distributions such as self-assessed health (SAH) data. This is an improvement over the existing measures of polarization that can be used only for cardinal variables. The new measures of polarization avoid one difficulty that the related measures for evaluating health inequalities face. Indeed, inequality measures are mean based, and since only cardinal variables have a mean, SAH has to be cardinalized to compute a mean, which can then be used to calculate an inequality measure. In contrast, the new polarization measures are median based and hence do not require to impose cardinal scaling on the categories. After deriving the properties of these new polarization measures, we provide an empirical illustration using data from the British Household Panel Survey that demonstrates that SAH polarization is also a relevant question on empirical grounds, and that the polarization measures are adequate to evaluate polarization phenomena whereas inequality measures are not adequate in these cases.

  • It wasn’t me, it as them!” A study of social influence in risky behaviour by adolescents Article dans une revue:

    Many years of concerted policy effort in Western countries has not prevented young people from experimenting with cigarettes, alcohol and marijuana. One potential explanation is that social interactions make consumption « sticky ». We use detailed panel data from the Add Health survey to examine risky behavior (the consumption of tobacco, alcohol and marijuana) by American adolescents. We find that, even controlling for school fixed effects, these behaviors are correlated with lagged peer group behavior. Peer group effects are strongest for alcohol use, and young males are more influential than young females. Last, we present some evidence of non-linearities in social interactions.

  • Should market liberalization precede democracy? Causal relations between political preferences and development Pré-publication, Document de travail:

    Cet article tente de discerner des relations de causalité entre démocratie et marché en distinguant contexte et préférences. Il s’agit de savoir si le développement du marché favorise le soutien à la démocratie et, inversement, si le développement de la démocratie est propice à l’adhésion des citoyens au marché. Ce travail s’appuie sur une nouvelle enquête, Life in Transition Survey, conduite en 2006 par la BERD dans 26 pays en transition. Notre stratégie d’identification repose sur l’exploitation de la situation particulière des zones-frontalières présentes au sein de l’enquête. Nos résultats suggèrent que la démocratie est favorable à la demande de marché tandis que le développement du marché ne conduit pas è une plus forte demande de démocratie. L’argument relativiste selon lequel la préférence pour la démocratie est un effet endogène du développement économique n’est donc pas validé par nos données.

  • Conditions de collecte et santé subjective : analyse sur données européennes Pré-publication, Document de travail:

    Il est banal de dire que la santé subjective, la mesure la plus répandue dans les questionnaires, est sujette à divers biais de mesure. Une question en suspens reste de déterminer en quoi l’information recueillie dépend des conditions de collecte, ces dernières variant considérablement entre les pays et les enquêtes. Dans cet article, on a fait appel à un dispositif quasi-expérimental présent dans la base de données SHARE afin d’étudier deux effets du mode de collecte : le placement de la question de santé déclarée dans le questionnaire ; et la formulation des modalités de réponse proposées. Nous trouvons que les deux effets sont significatifs. L’effet de placement est particulièrement homogène. Dans tous les pays de l’échantillon, les individus enquêtés déclarent en moyenne des niveaux de santé subjective supérieurs après avoir répondu à un questionnaire détaillé de santé. Nous avons pu également mettre en évidence que les variables de santé fonctionnelle mobilité et limitations quotidiennes, sociales et sensorielles étaient mieux discriminées lorsque la variable de santé déclarée se trouvait après le questionnaire détaillé. L’effet moyen de formulation est fort, et moins homogène que l’effet de placement : il varie notamment en fonction des pays.

  • Ambition and jealousy. Income interactions in the « Old » Europe versus the « New » Europe and the United States Pré-publication, Document de travail:

    Cet article tente de vérifier la conjecture selon laquelle la répartition du revenu affecte le bien-être des individus de manière différente suivant le degré de mobilité et d’incertitude qui caractérise leur environnement économique. L’accent est mis sur le lien entre satisfaction subjective et revenu du groupe de référence professionnel. Une analyse micro-économétrique portant sur plus d’un million d’observations permet de mettre en évidence une différence transatlantique dans la perception subjective des inégalités, c’est-à-dire une opposition entre les économies stabilisées de la « vieille Europe » d’une part, et les environnements plus mouvementés de la « nouvelle Europe » (centrale et orientale) et des Etats-Unis d’autre part.

  • La croissance rend-elle heureux ? La réponse des données subjectives Pré-publication, Document de travail:

    Le recours aux données subjectives permet d’analyser le lien entre revenu et bien-être individuel. Depuis le paradoxe d’Easterlin, de nombreux travaux ont essayé d’expliquer pourquoi au niveau agrégé, la croissance du revenu national ne semblait pas nécessairement entraîner celle du bien-être. L’ensemble de travaux empiriques présentés ici mettent au jour des phénomènes de comparaison de revenu, d’adaptation et d’anticipations qui, se compensant, rendent parfois invisible le lien agrégé entre croissance et bonheur. Au total, cet ensemble de travaux montre que les individus évaluent leur situation à l’aune de leurs aspirations ; celles-ci jouent un rôle favorable ou néfaste, selon qu’elles sont perçues comme potentiellement réalisables ou non.

    This paper is dedicated to the empirical exploration of the welfare effect of expectations and progress per se. Using ten waves of the Russian Longitudinal Monitoring Survey, a panel household survey rich in subjective variables, the analysis suggests that for a given total stock of inter-temporal consumption, agents are more satisfied with an increasing time-profile of consumption: they seem to have a strong « taste for improvement ».

  • Temperant portfolio choice and background risk: evidence from France Pré-publication, Document de travail:

    Dans cet article, nous nous intéressons aux comportements de tempérance des investisseurs qui veut que leur demande d’actifs risqués diminue avec le risque revenu (substitution des risques) et les contraintes de liquidité. Les modèles de portefeuille plus récents ont également mis l’accent sur l’importance de la corrélation entre le risque revenu et celui du portefeuille financier. Les données de l’enquête DELTA-TNS 2002 nous ont permis de tester ces modèles en utilisant une variable proxy pour la corrélation anticipée des risques. Alors que le risque revenu n’influence pas la demande d’actions des ménages qui anticipent une corrélation négative, son impact est négatif pour ceux qui voient une corrélation positive ou nulle. Ce résultat est conforme aux prédictions de la théorie.

  • Segregation, entrepreneurship and work values: the case of France Pré-publication, Document de travail:

    Cet article analyse l’interaction entre l’intégration au sein du marché du travail, l’attachement au travail et le capital social propre à chaque minorité « ethnique ». Nous présentons un modèle de segmentation du marché du travail au sein duquel les différentes minorités sont pourvues d’un certain réseau d’entrepreneurs qui joue un rôle central dans l’accès à l’emploi et la transmission de l’attitude vis-à-vis du travail. Nous illustrons cette analyse grâce à une enquête française contenant de nombreuses questions relatives à l’importance subjective du travail et au sein de laquelle la population immigrée est délibérément sur-représentée. En première analyse, les données révèlent une différenciation forte au sein des immigrés de première et seconde génération, du point de vue de l’accès à l’emploi et du rapport subjectif au travail selon qu’ils sont issus d’Afrique du Nord ou d’Europe du Sud. Ces caractéristiques diffèrent également de celles des Français non issus de l’immigration (depuis deux générations). Outre les explications classiques en termes de différence culturelle et de discrimination, l’analyse statistique montre que ces différences sont totalement expliquées par l’importance du réseau d’entrepreneurs local propre è chaque minorité.

  • Inégalités patrimoniales et choix individuels : des goûts et des richesses Ouvrages:

    L’objectif principal de cet ouvrage est, à partir d’un questionnement multiforme, de proposer une méthode originale de mesure des préférences des épargnants français vis-à-vis du risque et du temps. Les enjeux soulevés sont nombreux. À quoi attribuer les inégalités de patrimoine : aux différences de goûts des individus ou au fonctionnement même des marchés? Peut-on » profiler » l’épargnant selon ses préférences, des têtes brûlées aux bons pères de famille, afin de mieux le conseiller dans sa gestion patrimoniale? Le Français est-il à ce point incompétent ou si peu informé pour préparer sa retraite qu’il faille au nom d’un paternalisme nouveau, » l’éduquer » financièrement à l’épargne? Autant de questions auxquelles ce livre tente d’apporter des réponses… (présentation éditeur)

  • Conditions de collecte et santé subjective : analyse sur données européennes Article dans une revue:

    La santé auto-déclarée, la mesure de santé la plus répandue dans les questionnaires, ne constitue qu’un reflet biaisé de l’état de santé réel. Mais il est difficile d’isoler et d’évaluer ces biais. En particulier, en quoi l’information recueillie dépend-elle des conditions de collecte, ces dernières variant considérablement entre les pays et les enquêtes ? Le dispositif présent dans la base de données Share permet d’étudier deux effets du mode de collecte : le placement de la question de santé déclarée dans le questionnaire et la formulation des modalités de réponse proposées. Les deux effets comptent : le niveau moyen de santé, la distribution des états de santé et les liens de la santé avec d’autres variables sont modifiés lorsque l’on change les conditions de collecte. L’effet de placement est homogène : dans tous les pays de l’échantillon, les individus déclarent en moyenne des niveaux de santé déclarée supérieurs après avoir répondu à un questionnaire détaillé portant sur leur état de santé réel, à ceux indiqués quand la question est posée avant. Les répondants semblent également accorder une plus grande importance à la dimension fonctionnelle de la santé mobilité et limitations quotidiennes, sociales et sensorielles lorsque la variable de santé déclarée se trouve après le questionnaire détaillé. La formulation des modalités de réponse proposées aux enquêtés modifie également la mesure de la santé auto-déclarée. Par exemple, la Suède apparaît comme le pays le plus sain (sur dix pays) avec une première formulation, alors qu’elle passe au cinquième rang avec une seconde. De plus, nous avons pu montrer que la formulation sélectionnée par la Rand Corporation dans le cadre de son questionnaire Short Form 36, généralisée depuis dans la plupart des questionnaires anglo-saxons, n’était pas plus discriminante, en termes de santé réelle, que la formulation généralement utilisée dans les questionnaires de santé d’Europe continentale.

  • Contrôle des activités illégales en présence d’un biais d’optimisme Article dans une revue:

    Le contrôle est l’un des instruments majeur de répression des activités illégales. Cette dimension est intégrée aux analyses économiques du crime sous la forme d’une probabilité de détection et fondée seulement sur l’aversion au risque. La psychologie cognitive montre que la perception des probabilités peut elle-même varier d’un individu à l’autre. Cet article propose une analyse expérimentale de ce type d’erreur de perception, qualifiée de biais d’optimisme, à partir d’une série de choix entre une activité légale et une activité illégale. Les traitements expérimentaux évaluent la mesure dans laquelle les modalités de contrôle peuvent, à probabilité donnée, influencer les biais d’optimisme. Les résultats suggèrent que les politiques de communication de lutte contre les activités frauduleuses doivent favoriser la perception idiosyncrasique du risque.

  • Effort and comparison income: Survey and experimental evidence Pré-publication, Document de travail:

    Cet article compare les données de l’enquête ISSP et celles issues d’un test expérimental d’un jeu d’échange de dons, afin d’identifier l’effet du statut et du revenu relatif sur l’effort au travail. Nous observons un effet important du revenu d’autrui sur les décisions d’effort individuelles dans les deux bases de données. Le rang de l’individu dans la distribution des revenus a un impact plus important sur l’effort que le revenu moyen des autres, ce qui sugg&àgrave;re que les comparaisons sont davantage ordinales que cardinales. Nous montrons en outre que, contrôlant pour le revenu et le rang personnel, l’étendue de la distribution des revenus au sein du groupe de référence compte, l’effort individuel étant d’autant plus élevé que le revenu est éloigné du bas de la distribution. Enfin, l’effort est aussi affecté par les comparaisons inter-temporelles : ceux qui ont per&ccdelil;u des revenus plus importants ou ont béféficié d’un rang plus élevé dans le passé exercent un effort plus faible à revenu courant donné.

  • Income and happiness: Evidence, explanations and economic implications Pré-publication, Document de travail:

    Il existe une importante littérature micro-économétrique qui démontre une corrélation positive et significative entre revenu et bien-être individuel. Or, le paradoxe célèbre de Richard Easterlin souligne que le bonheur moyen au niveau national n’a pas évolué depuis de nombreuses années, et ce malgré une expansion spectaculaire en termes de PNB par tête. Nous affirmons que les questions sur le bonheur utilisées dans les enquêtes sont de bonnes mesures d’utilité, et nous expliquons le paradoxe par les comparaisons de revenu. Ces comparaisons s’effectuent soit par rapport à un groupe de référence (comparaisons sociales), soit par rapport à soi-même dans le passé (habituation). Nous passons en revue les résultats économétriques, expérimentaux et neurologiques cohérents avec les comparaisons de revenu, et signalons les implications qui en découlent pour de nombreux domaines de recherche en économie.

  • A note on unhappiness and unemployment duration Pré-publication, Document de travail:

    Plusieurs analyses ont démontré que le chômage réduisait le bien-être individuel, mais le rôle de la durée du chômage dans cette relation reste ambigu. Ce papier fait appel aux données provenant de trois panels européens ; ces données longitudinales nous permettent de distinguer le phénomène psychologique d’habituation au chômage d’un effet statistique de composition (où les chômeurs les plus malheureux seraient plus susceptibles de sortir du chômage plus vite). L’analyse économétrique des données de panel ne conforte pas l’hypothèse d’habituation au chômage.

  • The curved relationship between subjective well-being and age Pré-publication, Document de travail:

    Cet article réagit à un courant de recherche récent sur le bien-être et l’âge, dont deux exemples importants sont Mroczek et Kolarz (1998) et Mroczek et Spiro (2005). Nous présentons de nouveaux résultats, à partir de données de panel britanniques. Nous signalons aussi, peut être à l’insu de nombreux de psychologues, l’existence d’une importante littérature en économie montrant une relation en forme de U entre bien-être subjectif et âge. Les résultats de cet article confirment cette relation en forme de U. Notre conclusion générale est que nous devrions essayer de rendre cohérentes les conclusions des travaux économiques et psychologiques; malgré des différences de style, économistes et psychologues ont beaucoup à apprendre les uns des autres.

  • Born to be mild? Cohort effects don’t explain why well-being is U-shaped in age Pré-publication, Document de travail:

    L’analyse statistique des données en coupe transversale fait apparaître une relation en U entre bien-être subjectif et âge. Dans ce papier, l’analyse de quatorze vagues de données de panel permet de distinguer entre un effet de cycle de vie et un effet fixe de cohorte qui dépend de l’année de naissance. Une analyse en panel avec effets fixes fournit toujours une relation en forme de U entre bien-être subjectif et âge. Cette relation en U est plus plate pour la satisfaction dans la vie que pour le mesure GHQ de stress mental. Le profil des effets de cohorte n’est pas le même ni pour les deux mesures de bien-être ni, à un moindre degré, pour les différents groupes démographiques. Les individus nés plus tôt font état d’un niveau du bien-être plus élevé et ce, indépendamment de leur âge actuel. Ce résultat se remarque plus particulièrement pour les femmes.

  • Individual preferences and the distribution of wealth Pré-publication, Document de travail:

    A partir d’un sous-échantillon de l’enquête « patrimoine 1998 » de l’Insee, nous avons construit 5 paramètres de préférence individuelle : l’attitude à l’égard du risque (aversion, prudence…), le taux de préférence pour le présent, le degré d’impatience àcourt terme et le coefficient d’altruisme familial ou non. Les effets de ces indicateurs de préférences sur les montants de patrimoine sont-ils significatifs et conformes aux prédictions des modèles microéconomiques d’épargne ? Etre plus prudent ou plus prévoyant augmente le montant de la richesse détenue. L’altruisme familial va aussi de pair avec une fortune plus élevée. Le patrimoine des ménages apparaît donc bien sous sa dimension plurielle : réserve de précaution, épargne pour les vieux jours et transmission pour les siens. Par contre, on observe sans surprise que le degré d’impatience, indicateur composite de réactions à court terme, n’a pas d’effet sur le niveau de l’accumulation, et qu’il en va de même pour l’altruisme « non familial ». Le gain explicatif obtenu avec les scores de préférence peut paraître modeste : du fait de l’extrême concentration des fortunes, l’hétérogénéité non observée n’est pas fortement réduite. Reste que, quantitativement, les effets de ces variables subjectives sont loin d’être négligeables, notamment pour la préférence temporelle : entre individus « extrêmes » (i.e. entre le plus « myope » et le plus prévoyant de l’échantillon), les écarts de patrimoine estimés vont ainsi de 1 à 10. Et une décomposition des inégalités de patrimoine à l’aide de l’indicateur de Theil montre que les paramètres de goûts pertinents ont un pouvoir explicatif supérieur à des variables comme l’origine sociale, le diplôme, le type de ménage, la taille d’agglomération, la présence de contraintes de liquidité ; seuls les facteurs explicatifs de référence (âge, revenu, CSP, héritage) font mieux.

  • Risk and time preferences: saver types Pré-publication, Document de travail:

    Selon la théorie de cycle de vie, le consommateur/épargnant maximise, sous diverses contraintes, une fonction d’utilité définie sur son horizon de vie: le comportement de ce dernier dépendra alors de paramètres de préférence personnels, soit de ses attitudes à l’égard du risque et du temps. Dans ce cadre, tout est fait pour séparer ces préférences (« aversion » et autres attitudes) à l’égard du risque, γ, de celles à l’égard du temps (préférence pour le présent), δ, en les caractérisant par des paramètres définis indépendamment. Paradoxalement, les prédictions de la plupart des modèles vont dépendre de manière cruciale de l’interaction entre les deux séries de paramètres : savoir seulement que l’individu est « risquophile », ou bien « myope » n’apporte qu’une connaissance limitée ; savoir qu’il est les deux à la fois renseigne bien davantage sur ses décisions d’épargne et de composition du patrimoine. On peut alors caractériser le comportement prédit pour quatre types d’agents : les bons pères de famille (γ élevé, δ faible), les entreprenants (γ faible, δ faible), les têtes brûlées (γ faible, δ élevé), les cigales prudentes (γ élevé, δ élevé). Une enquête récente de l’INSEE (« Patrimoine 1997 ») conforte la validité empirique des prédictions dans le cas de la France. A travers plus de 80 questions balayant divers domaines de la vie, on a construit pour chaque enquêté, sous forme de « scores » qualitatifs, des indicateurs relatifs de son attitude à l’égard du risque et de son degré de prévoyance à long terme. Comme prévu, le croisement des deux paramètres de préférence offre les conclusions les plus intéressantes. L’analyse économétrique du montant et de la composition du patrimoine accorde un pouvoir explicatif appréciable aux paramètres introduits en combinaison. Toutes choses égales d’ailleurs, les « bons pères de famille » accumulent sensiblement plus que les autres ; à l’inverse, les têtes brûlées détiennent moins de produits d’épargne-retraite que les autres, et la détention d’actions apparaît significativement la plus faible dans le groupe des cigales prudentes.

  • Deliver us from evil: religion as insurance Pré-publication, Document de travail:

    Ce papier souligne le rôle de la religion en tant qu’assurance contre les effets des événements négatifs de la vie sur le bien-être, et les implications économiques et sociales qui en découlent. Nous utilisons deux bases de données afin de mettre en évidence une relation positive entre religion et bien-être subjectif ainsi qu’un effet d’assurance de la religion. Les croyants de toutes les dénominations sont moins touchés psychologiquement par le chômage ; les Catholiques et les Protestants sont protégés contre les effets psychologiques négatifs de la séparation maritale. En revanche, bien que les Protestants soient protégés contre les effets du divorce, les Catholiques en souffrent plus que les non-croyants. Ces résultats ne découlent pas de l’endogénéité de la religion. Conformément à ces résultats sur le bien-être, on montre que les croyants sont plutôt opposés au divorce et à la création d’emplois pour les chômeurs par le gouvernement. Les chômeurs religieux sont également moins susceptibles de rechercher un emploi. Dans les données de panel, la satisfaction dans la vie des religieux est plus stable, comme impliquerait une assurance. Enfin, nous suggérons que la protection fournie par la religion contre le chômage peut remplacer l’assurance sociale : effectivement, allocations chômage et religiosité sont négativement corrélées en Europe.
