Séminaires
Groupe de travail Comportement
Le Groupe de travail Comportement offre un cadre régulier et convivial dans lequel un membre du groupe Comportement peut présenter des stratégies empiriques envisagées afin qu’elles puissent être discutées de façon informelle avant leurs mises en œuvre (protocole d’expérience, design d’enquête, etc).
Le Groupe de travail Comportement des UMRs CNRS, PjSE et CES se réunit chaque mois, soit le jeudi à Jourdan avant le séminaire Comportement, soit le vendredi à la Maison des Sciences Economiques avant le séminaire Economie et Psychologie. Si vous souhaitez présenter un projet en cours ou un article, contactez Liza Charroin (liza.charroin chez univ-paris1.fr) et Margherita Comola (margherita.comola chez psemail.eu).
Ce séminaire bénéficie d’une aide de l’État gérée par l’Agence Nationale de la Recherche au titre du programme d’Investissement d’avenir portant la référence
ANR-17-EURE-0001.

- DAGORN Etienne (INED) : The Roots of Gendered Behaviour : online experiment with teachers
- RésuméEvidence shows that teachers interact differently with boys and girls, grade them differently and provide different feedback and career advice. These gendered teaching practices have significant effects on boys' and girls' school achievement and educational choices, especially in scientific subjects where strong gender stereotypes prevail. However, little is known about the behavioral roots of such gendered practices. We first develop a theoretical model to rationalize teachers' potential gendered behaviour. We then empirically test those mechanisms using an online experiment with secondary education teachers from several subjects. Teachers are asked to evaluate fictitious school transcripts for which we randomly change the information displayed, namely the student's gender (to measure the extent of their gendered practices). Then, they are invited to play a set of gender-blind and gender-revealed dictator games (to measure gender identity) and to take an implicit association test (to measure gender implicit biases). The preliminary results will be presented during the talk.

- RésuméOur research project aims to understand consumers' attitudes towards second-hand goods, specifically related to image concerns in the clothing industry, through two connected survey experiments. The first survey investigates if there is a negative perception of buyers of second-hand clothes. The second survey aims to improve people's negative perception of second-hand clothes by presenting them with unbiased opinions from the first survey and asking them to choose between vouchers for first or second-hand clothes.

- KLOPFENSTEIN Aurélien : Cognitive Barriers to Impact Investing
- RésuméSustainable investing has been gaining traction as a means to speed up the environmental transition. Recent theoretical work highlights that a sustainable investor looking to maximize their impact should focus not just on their own stocks' emissions, but should also internalize the whole market's emissions – following a broad mandate. Sustainable investors should therefore coordinate with other fellow sustainable investors, as well as with the market as a whole. The goal of this project is to explore behavioral barriers to broad-mandate investing. In a first experiment, we find that some market structures make broad-mandate investing very counterintuitive for investors, irrespective of their preferences. Further experiments are planned in order to identify the precise cognitive mechanism at play

- MAYAUX Damien (PSE) : Utility and Contrast in Evidence Accumulation Models
- RésuméCombining response times to choice data helps reveal preferences when decision-makers make mistakes. Evidence accumulation models, such as the Decision Diffusion Model (DDM) or the Linear Ballistic Accumulator, generate a joint distribution of choice and response times given a set of alternatives and their utility. These models have been shown to fit equally well empirical data for a given choice set. However, they generate diverging predictions about the effect of changing the utility of an alternative. In this paper, I clarify theoretically how utility enters these models and how they can be used for revealing preferences. I characterize evidence accumulation models by their range – the set of all distributions that can be generated - and their contrast - the extent to which increasing the utility of one alternative slows down the choice of another. Evidence accumulation models have a similar range, but disagree on the contrast. One implication is that all these models would be equally suitable for revealing preferences if their contrast was properly calibrated.. I propose a tractable framework for this aim and give general conditions under which it is applicable. I illustrate my theoretical results with simulated data from a DDM model.

- FERNANDEZ-URBANO Roger : How Locus of Control Predicts Subjective Well-being and its Inequality: The Moderating Role of Social Values
- RésuméPrevious research has established the central role of an individuals' locus of control (LoC) in influencing subjective well-being. However, earlier studies have predominantly omitted an exploration of potential moderating factors at the country-level and have rarely delved into the influence of LoC on an important yet often-overlooked dimension of well-being—namely, subjective well-being inequality. Addressing these gaps, this study examines the association between individuals' LoC and subjective well-being, considering both the mean and inequality aspects. Additionally, it explores the moderating influence of country’s social values, particularly the individualism-collectivism dimension. Utilizing data from the Integrated Values Survey, comprising 170,000 individuals across 37 countries from 1996 to 2022, our study confirms a strong positive relationship between LoC and subjective well-being while also unveiling a strong negative relationship with subjective well-being inequality. Moreover, it demonstrates that country’s social values exert significant moderation effects on the relationship between LoC and subjective well-being, affecting both the mean level and inequality aspects, albeit in opposing directions. By employing the Oaxaca-Blinder decomposition, our findings support the importance of structural effects. Understanding how increasing LoC shapes people’s wellbeing in a society holds implications for policymaking and contributes to ongoing discussions on collective choice and inequality

- SCHÜTZ Rafael : The limits to universalism
- RésuméSurveys, ballot measures, donations, and consumer spending alike reveal a growing concern for the welfare of animals. What is driving this phenomenon? Does it follow a general shift toward more universalist attitudes, or are social preferences for humans and animals substitutes? I propose a representative survey experiment to measure the distribution, interdependence, and determinants of universalist attitudes toward various human or animal out-groups. Attitudes would be elicited in two ways: (1) via previously validated hypothetical money allocation tasks between an in-group member and an out-group representative; (2) by allowing respondents to make donations to NGOs that focus on a specific out-group. Subjects would be randomly exposed to a narrative about a direct, positive interaction between an in-group member and an out-group member. This would allow to study the role of perceived distance to the out-group in shaping other-regarding preferences

- LAGO RODRÍGUEZ Manuel Estevo : Unraveling Gender Norms: The power of information provision on the preferential promotion of women
- RésuméIn this paper, we study whether variations in gender norms and, significantly, separating the effects of 1st and 2nd order beliefs can affect attitudes towards the preferential promotion of women to senior-level positions. We examine whether providing information on what others believe to be socially acceptable (2nd order) and information that may change personal beliefs (1st order) impacts attitudes towards promoting women. To the best of our knowledge, this is the first paper that aims to disentangle the causal effect of 1st and 2nd order beliefs separately in the context of gender norms

- VARDAXOGLOU Laurence (PSE) : Effect of misinformation on voting in the laboratory
- SAVEY Lily
- RésuméFor health-related matters, being misinformed leads individuals to make bad decisions. In politics, it is less obvious. Although misinformation has been shown to influence voting decisions, this is not necessarily a deviation from rational voting. An individual might indeed be tricked into a non-rational voting decision, or motivated to opt for the candidate who maximises the utility of their vote. Our aim is to explore the extent to which different kinds of misinformation obstruct rational voting. We propose to study rational voting in the laboratory, as it allows us to control for important factors that are inevitably imprecisely measured using survey data.

- WEBB Duncan (PSE) : Silence to Solidarity: Using Group Dynamics to Reduce Anti-Transgender Discrimination in India
- RésuméDiscrimination is often believed to be the result of deep-seated prejudice against a minority, or of beliefs that can only change upon the revelation of new information. But social context — in particular, how people behave differently in groups — may be a more important determinant of discrimination than traditional theories of discrimination suggest. This paper shows that involving majority-group members in a group discussion and hiring decision can sharply reduce hiring discrimination against a stigmatized minority. I focus on discrimination against the transgender community in India, a highly visible and economically vulnerable group. In a control condition, participants on average sacri?ce almost double their daily food expenditure to avoid selecting a transgender individual to deliver food to their home. But if they were earlier involved in a group discussion and collective hiring decision with two of their neighbours, they no longer discriminate at all, even when making subsequent choices in private. This effect is stronger than the effect of informing people about the legal rights of transgender people, and the reduction in discrimination partially persists until around 1 month later. The results appear to be driven by the emergence of a strong pro-trans norm in the groups, supported by pro-social reasons for selecting transgender workers that persuade others to discriminate less.

- MAYAUX Damien (PSE) : Welfare effects of salient marketing cues
- RésuméOnline marketplaces are full of salient-yet-ambiguous marketing cues that steer consumers towards specific items. Platforms enjoy great freedom in choosing how cues look like (visual design) and which products they are assigned to (attribution mechanism). I study in an online choice experiment the effect of some visual design / attribution mechanism pairs on consumer choice and welfare. My main hypothesis is that, for some visual designs that are overtly positive - a golden thumb, a green circle - participants tend to follow blindly the cue no matter if it is assigned on good or bad items, while for some other visual designs that are salient but less positive - a blue road sign or a message in black font with capital letters - participants perform better than without the cue when it is on the best items and comparably to this baseline otherwise.

- ZAPPALÀ Guglielmo (PSE) : Drought exposure and accuracy: Motivated reasoning in climate change beliefs
- RésuméDespite scientific consensus, there is no unanimity among citizens in the beliefs about climate change. Understanding how people form beliefs about climate change and what drives their interpretation of climatic events is essential, especially in developing countries and among agricultural communities, who may most suffer from climate change consequences. Using survey data from rural households in Bangladesh matched with objective drought data, this paper studies how long-term average drought exposure and short-term deviations shape belief formation and accuracy in recollecting past drought events. In order to further investigate how agents interpret these past drought events, I use an instrumental variable approach to test and validate that individuals are subject to confirmation bias. The results show that the probability of overestimating the number of past drought events and the intensity with which individuals overestimate are significantly biased in the direction of their prior beliefs. The findings highlight the need of models that account for behavioral factors such as confirmation bias and motivated reasoning to study climate change preference formation, and its implications for effective communication.

- RésuméThis paper analyzes the incentives that arise within an organization when communication is restricted to a particular network structure (e.g., a hierarchy). We show that restricting communication between the principal and agents may create incentives for the agents to misbehave when transmitting information and tasks throughout the organization. Such incentives can render the principal's most preferred outcome infeasible and therefore introduces a trade off between the cost of communication borne by the principal and the benefit of curbing incentives to deviate induced by the communication structure. To remedy this issue, we provide necessary and sufficient conditions on the topology of the network of communication such that restricting communication to a particular network does not restrict the set of outcomes that the principal could otherwise achieve. In this sense, we show that for any underlying incentives and any outcome available when communication is unrestricted, there exists a (finite) communication scheme restricted to a particular network that implements this outcome (i.e., does not induce agents to misbehave in the communication phase) if and only if that network satisfies our conditions.
