This paper investigates the role played by firms' managerial skills in the heterogeneous reaction of exporters to common exogenous changes in their international competitiveness (here captured by changes in the real exchange rate). Relying on a simple theoretical framework, we show that firms with better managerial skills have higher profits, market power, and are able to adapt their markup more when faced with a competitiveness shock. We test this prediction relying on detailed firm-product-destination level export data from France for the period 1995-2007 matched with specific information on the firms' share of managers. Our findings show that managerial intensive firms have larger exporter price elasticity to real exchange rate variations. The effect is not trivial: in the wake of a depreciation, exporters whose management intensity is one standard deviation higher than the average, increase their prices by 51% to 73% more than the average exporter. This finding is robust to controlling for the alternative explanations suggested by the previous literature to explain the heterogeneous pass-through of firms.

Using monthly firm-level exports and imports over 1993–2020, we uncover four facts: (i) deviations of large exporters from the average growth rate explain a large share of aggregate fluctuations; (ii) an important source for these deviations is the top exporters’ higher loadings on common shocks; (iii) the stronger reaction of the top 1% exporters to the GFC and Covid crises contributed to the export collapses; (iv) a higher elasticity to large demand shocks, not a different exposure to global value chain shocks, contributes to this stronger reaction. The results show that idiosyncratic reactions of large firms to common shocks matter for aggregate export fluctuations, and are especially relevant for the trade collapses of the 2008/2009 crisis and the Pandemic.

This paper introduces a causal machine learning approach to investigate the impact of the EU-Canada Comprehensive Economic Trade Agreement (CETA). We propose a matrix completion algorithm on French customs data to obtain multidimensional counterfactuals at the firm, product and destination levels. We find a small but significant positive impact on average at the product-level intensive margin. On the other hand, the extensive margin shows product churning due to the treaty beyond regular entry-exit dynamics: one product in eight that was not previously exported substitutes almost as many that are no longer exported. When we delve into the heterogeneity, we find that the effects of the treaty are higher for products at a comparative advantage. Focusing on multiproduct firms, we find that they adjust their portfolio in Canada by reallocating towards their first and most exported product due to increasing local market competition after trade liberalization. Finally, multidimensional counterfactuals allow us to evaluate the general equilibrium effect of the CETA. Specifically, we observe trade diversion, as exports to other destinations are re-directed to Canada.

In an increasingly uncertain environment, firms are differently exposed to shocks and may or may not bear the costs of reorganizing their value chain by reshoring or offshoring. This paper is based on a survey of French firms on the decision to reorganize part of their value chain between January 2018 and December 2020, in order to study the prevalence and the modalities of such reorganizations. Such decision turn out to be rare, carried out by firms with a higher share of skilled workers, in manufacturing rather than in services, and dominated by multinational firms. Although high-skilled firms reorganize more, the reorganized business functions are less skillintensive and more intensive in routine tasks. Activities that are more intangibles-intensive are more likely to be reorganized within the firm. Finally, apart from reshoring in France, activities that are offshored are located close to France. India, which combines low average wages with a large pool of highly skilled labour, receives a disproportionate share of skill-intensive activities.

Can NGOs contribute to the implementation of Labor Laws in a developing country? We exploit as a quasi-natural experiment the renegotiation of the Generalized System of Preferences (GSP) between the US and Indonesia in 1994, which induced the Indonesian government to raise the level of the legal minimum wage. Using data from Indonesian manufacturing firms, a diff-in-diff analysis and an event study show that the activism of workers’ rights groups helped increase firm-level average wages up to the minimum-wage level, not only inside but also outside the export sector. Labor NGO activism helped to implement the new minimum wage standards in a country that lacked strong governmental institutions.

We analyse how the combination of firm-level financial fragility and country-level financial constraints affect productivity growth in France, Italy and Spain. We first show that, although high leverage weighs on firm-level productivity in all three countries, more leveraged firms seem to suffer more from financial constraints only in Italy. In a second step, we show that this apparent specificity of Italian firms is related to the relatively short maturity of their debt. These results highlight the importance of liquidity constraints during periods of financial stress such as the Global Financial Crisis of 2008 or the European sovereign debt and banking crisis of 2011-13.

We study how technology adoption and changes in global value chain (GVC) integration jointly affect labor shares and business function specialization in a sample of 14 manufacturing industries in 14 European countries in 1999–2011. Increases in upstream, forward GVC integration directly reduce labor shares, mostly through reductions in fabrication, but also via other business functions. We do not find any direct effects of robot adoption; robotization affects labor only indirectly, by increasing upstream, forward GVC integration. In this sense robotization is “upstream-biased”. Rapid robotization in China shaped robotization in Europe and, therefore, relative demand for labor there.

Les conséquences économiques et environnementales des politiques françaises de transition énergétique doivent s’envisager dans le cadre d’une économie ouverte. Tout d’abord, le rythme des efforts et les modalités de la décarbonation de l’activité économique sont en partie dictés au niveau européen, comme dans le cas du marché de quotas d’émission pour les industries hautement émissives. Mais surtout, l’Accord de Paris inscrit l’effort français au sein d’une variété d’engagements nationaux de décarbonation, tant en termes d’ambition que d’instruments mis en œuvre pour y parvenir. Cette diversité des efforts et instruments au niveau international contribue à déterminer les effets économiques des choix faits en matière de politiques climatiques adoptées au niveau européen et français. Ce rapport propose un tour d’horizon synthétique de cette dimension internationale des politiques de transition énergétique. En dépit d’éléments communs, notamment leur objectif final de réduction de l’empreinte carbone de l’activité économique, les politiques climatiques des différents pays sont hétérogènes, qu’il s’agisse de leur ambition – à savoir le niveau de leurs engagements en termes de décarbonation – ou des politiques (prix, réglementations, subventions ou crédits d’impôt) mises en œuvre. Il est dès lors illusoire de tenter de réduire les effets de cette hétérogénéité à une métrique commune de l’effort de chaque pays, comme le serait un équivalent prix des mesures réglementaires ou incitatives en place dans les différents pays.

To meet the targets of the EU’s Fit for 55 package, the European Commission proposed in July 2021 to implement a Carbon Border Adjustment Mechanism (CBAM) to replace free allocation of Emission Trading System (ETS) allowances for the most trade-exposed emitting industries. CBAM aims to prevent carbon leakage and restore a level playing field in high-emitting industries. Its design, as voted by the European Council in March 2022, by the Parliament in June, and ultimately amended by a provisional agreement between the Council and the European Parliament in December 2022, raises several issues. This paper aims to quantify the economic and environmental impacts of different choices regarding this design. Simulations are based on a dynamic general equilibrium model representing imperfect competition, input–output relations, greenhouse gas emissions, the endogenous price of emission quotas and the presence of free allocation of allowances. We show that CBAM is effective in reducing carbon leakage. But its design increases the price of carbon in the European Emissions Trading Scheme. Competitiveness losses in export markets are expected for downstream sectors that are not covered by the CBAM, as well as for European exporters of high-emitting industries, even in the presence of rebates.

International trade contributes directly to global greenhouse gas emissions, as the carbon content of high-emission products is priced differently in different countries. This phenomenon is termed carbon leakage. Thus, not putting a price on carbon is theoretically equivalent to an export subsidy, although that would be difficult to challenge in the context of multilateral trade law. Leakage can be alleviated by pricing the carbon embedded in imported products through a border carbon adjustment (BCA), be it a tax, a carbon tariff, or a regulation requiring the purchase of emissions allowances. The design of a BCA is a compromise between environmental effectiveness in preventing leakage, economic effectiveness in preserving competitiveness and ensuring acceptability, technical feasibility of the implementation, and World Trade Organization compatibility. An import-limited BCA is more effective than free emissions allowances in reducing leakage, but it does not preserve the export competitiveness of the country imposing it.

This paper explores the economic impacts of preferential trade agreements, conditional on their level of ambition. It clusters 278 agreements, encompassing 910 provisions over 18 policy areas and estimates the trade elasticity for the different clusters. These elasticities are used in a series of general-equilibrium counterfactual situations for endowment economies, revealing that deepening existing agreements (the intensive margin of regional integration) could boost world trade by 3.9 percent and world GDP by 0.9 percent. The expected gains from deepening agreements within or across regions vary depending on the initial depth of agreements and the size of regional markets.

This article investigates the effect of shocks to the occupational structure of exporting firms induced by the introduction of technical barriers to trade (TBTs) in importing countries. We rely on specific trade concerns data to identify trade‐restrictive TBT measures, combined with matched employer‐employee data for French exporters over the period 1995–2010, and information on the product‐destinations served by each exporter. Controlling for time‐invariant firm/occupation fixed effects and for time‐varying sector/occupation shocks, the 2SLS estimates show that exporting firms adapt to the imposition of TBTs at destination by increasing the share of managers at the expense of blue collars, white collars and other professionals.
