Résumé : This article contributes to the study of poverty in data-deprived countries by providing a comprehensive assessment of poverty in Lebanon, which has had an unusual sequence of crises since October 2019. We build (i) monetary-based measures using income and expenditures, (ii) two deprivation-based measures, named Base MPI and Augmented MPI, with the latter capturing missing dimensions of institutional and socio-emotional deprivations, and (iii) a measure of perceived poverty. Our analysis draws on unique primary data collected in 2023 through a nationally representative survey of 2,402 households. Our results indicate headcounts of 31% (income-based) and 30% (expenditure-based). Multidimensional poverty is less widespread than existing estimates indicate, and measures based solely on functionings underestimate its extent. The Base MPI headcount is 26.6%, rising to 34% when institutional and socio-emotional deprivations are included (Augmented MPI). Poverty is subject to a significant upward perception gap: depending on the poverty measure used, 40% to 47% of households consider themselves poor, while they are not identified as such. Our findings point to substantial inequality in both income and expenditure, at 63% and 54%. Using publicly available pre-crisis household data from 2018, we find that multidimensional poverty increased significantly and the perception gap widened by threefold in the aftermath of the crisis.

Résumé : To counter carbon leakage that could jeopardize its Net Zero strategy by 2025, the European Commission adopted, through the CBAM regulation, a pricing mechanism for imported emissions coupled with the phasing out of free allowances on its carbon market (EU-ETS). The speed of this phasing out, which will be complete by 2034, raises questions about its impact on industrial activity within the European Union. To address these questions, this article adapts the standard model of monopolistic competition used in international economics in two ways. First the model is extended by incorporating a non-zero price super-elasticity of demand in the spirit of Klenow and Willis (2016). It results in a variable carbon cost-through that depends on the price of the good. Second, the model is extended to a value chain with an upstream sector with heterogeneous firms covered by the carbon market and a downstream sector that is not covered. It allows for the integration of four types of carbon leakage: i) substitution in the domestic market; ii) substitution in foreign markets; iii) reshuffling along the value chain iv) relocation of activities. The last type of leakage is tackled with by distinguishing between short-term and long-term equilibrium, leveraging the result that the Coase principle of independence no longer holds in the long run. The model is calibrated on pre-CBAM data for the steel value chain with steel production as the upstream sector and the automotive industry as the downstream sector. Simulations are then implemented to compare the official CBAM regulation with an alternative scenario without the phasing out of free allowances. Whatever the scenario considered, drastic changes in the structure of the upstream sector are expected, with both an increase in the total domestic production level and a drop in the average carbon intensity. It is also shown that the phasing out of free allowances mainly increases the aggregate domestic prices of the upstream and downstream goods and reduces the production level of the domestic downstream sector. In contrast, the impacts on the production of the upstream sector are limited.

Résumé: In this presentation, we introduce and discuss new formulations of stochastic volatility models that extend both the classical stochastic volatility model and the logGARCH model. These formulations enhance the flexibility and explanatory power of both models in capturing volatility dynamics. We present several probabilistic properties, including strict stationarity, second-order stationarity, and the existence of higher-order moments. We also describe the parameter estimation procedures for each model. Finally, we assess the performance of these formulations through applications to financial series.

Paper

Abstract : This paper examines how participation in global value chain (GVC) influences domestic CO₂ emissions embodied in China’s manufacturing exports via industrial backward linkages (industrial dependence), structural backward linkages (resource reallocation, rarely studied in literature), and forward linkages combined with GVC position (upgrading). Using a dynamic panel of 16 manufacturing industries from 2000–2018 and a bias-corrected fixed-effects estimator, we find that backward linkages significantly increase emissions through scale and reallocation effects, with an industrial inverted-U pattern. In contrast, forward linkages and upstream GVC positioning consistently reduce emissions by facilitating the diffusion of technology, upgrading, and cleaner production. China’s unique dual GVC structure, where carbon-intensive downstream assembly coexists with low-carbon upstream upgrading, suggests that GVC integration does not automatically lower emissions; the reduction of domestic CO2 emissions depends critically on industrial capacity for upgrading and innovation, which are essential for achieving China’s 2030 peak and 2060 carbon neutrality targets.

Résumé : The paper evaluates the effects of R&D place-based policies implemented by regional governments. We constructed a unique database that provides detailed information on direct R&D support from France’s leading Auvergne-Rhône-Alpes Region from 2009 to 2021, while controlling for national direct and indirect R&D support policies. Using a staggered event study design, we assess the policy's impact on firm-level employment, turnover, exports, and financial performance. The econometric results reveal that innovative firms experience a gradual increase in turnover and employment after receiving regional support, with a more pronounced effect emerging approximately eight years later. Additionally, our findings highlight interaction effects between different instruments and government levels.

Résumé : In many industries, platforms compete with incumbents that are open to all consumers, whereas platforms require user affiliation. Consequently, platforms face two layers of competition: for the market, to attract users, and in the market, to compete with incumbents. We develop a dynamic model integrating these layers, showing that as platform affiliation grows, in the market competition intensifies, pushing incumbents toward more aggressive pricing. Conversely, for the market competition diminishes, reducing the platform’s incentive to compete aggressively. This interplay generates dynamic pricing behavior that can be non-monotonic over time, capturing the shifting incentives driving platform-incumbent competition across both dimensions.

Résumé : Despite France’s 2015 Energy Transition Law aiming to cut municipal waste by 10%, waste increased by 6% (2009–2021). Better waste sorting and recycling are key to reducing the environmental impact of the waste management system and transitioning toward circular-economy societies. Household participation is crucial, influenced by socio-economic factors, individual motives, and public policies like unit-based pricing (UBP). While UBP can reduce waste and improve sorting, its effectiveness remains largely debated. This study assesses UBP acceptability in France using a Discrete Choice Experiment (DCE) and examines the role of behavioral incentives (nudges and boosts) in shaping this acceptability. Respondents are divided into three groups: a control group, a nudge group (exposed to a video on waste consequences), and a boost group (receiving sorting guidance). Preliminary results (n=300) show a limited impact of interventions on UBP acceptability, which we approximate using WTP/WTA measures. Respondents favor door-to-door collection for unsorted waste and reject weight-based UBP, preferring deposit-based systems. Despite this, households generally support UBP for environmental and cost-related reasons.

Résumé : This paper develops a framework for decomposing inequality of opportunity into racial stratification and social class components. We derive novel dominance conditions that enable robust rankings of joint distributions of income and birth circumstances, and develop additional dominance criteria for restricted classes of indices reflecting either pro-poor or meritocratic perspectives. Our framework includes an estimation approach and statistical tests for these stochastic dominance conditions, ensuring practical application with survey data. Using Health and Retirement Study data, we analyze inequality of opportunity in earnings among aging U.S. populations between 2010-2020. While social class-based inequality decreased for certain classes of indices, the racial stratification component increased, driving overall rising inequality of opportunity.

Résumé : This paper investigates the impact of noisy news shocks about aggregate Total Factor Productivity (TFP) on business cycle dynamics. We begin by proposing a simple semi-parametric statistic that combines moment conditions between noisy signals and present or future changes in TFP to estimate the noise-to-signal ratio and the impulse response function (IRF) of news shocks to TFP. Building on this first-step, we develop a multi-step procedure, based on local projection, to estimate the IRFs of both news and noise shocks and evaluate their respective contributions to business cycle fluctuations. Simulation experiments confirm the robustness of the procedure in a general setting. Finally, applying the method to U.S. data, we find that noise in TFP plays a minor
role in explaining business cycle variations.

Résumé: Cet article examine les cycles politico-budgétaires régionaux lors des élections nationales dans les pays et régions de l'Union Européenne entre 1995 et 2022, en mettant l'accent sur le rôle des règles fiscales nationales et supranationales. Nous trouvons des preuves solides que les élections nationales sont associées à une augmentation des dépenses publiques régionales et à une réduction des taux d'imposition sur le revenu et la richesse. Tandis que des règles fiscales strictes contraignent efficacement les cycles politico-économiques liés aux dépenses, elles encouragent simultanément la manipulation par le biais de la fiscalité. Cet effet est observé dans presque tous les pays européens, tant au niveau national que régional, avec des variations selon les systèmes électoraux et politiques spécifiques. Nous montrons également que les gouvernements de droite s'engagent dans des PBC opportunistes à la fois liés aux dépenses publiques et à la fiscalité, tandis que les gouvernements de gauche se concentrent principalement sur des manipulations fiscales. De plus, les gouvernements de gauche nouvellement élus adoptent une politique fiscale conservatrice, tandis que les gouvernements de droite maintiennent généralement le status quo fiscal.

Résumé: This paper investigates the donor's choice of climate aid and its impact on global environmental quality and the donor and recipient countries' economic development, in a context where the recipient government may misallocate aid. We adopt a two-country and two-period model in which the aid donor choice is motivated by interest and altruism, while the recipient government allocates this aid between environmental action and its interest, decides on tax effort and public spending. Our analytical framework leads to the following points. First, at the political-economic equilibrium, the tax effort in the recipient country decreases with the amount of aid received, resulting in reduced tax revenue, while the misallocation of climate aid decreases with the recipient government’s concerns for environmental quality and population welfare. Second, the optimal aid chosen by the donor increases with its income, its concerns for the global environmental quality, and the efficiency of the recipient's environmental policy, but decreases with the recipient's initial income. Third, when accounting for climate aid and environmental policies, the global environmental quality is improved with the environmental concern of the population in both countries, the efficiency of the environmental policy in the recipient country, and the donor's altruism degree. Finally, our results indicate that climate aid policy is always GDP and welfare-improving for the recipient despite the aid misallocation, while this positive effect is subject to conditions for the donor.

Résumé : We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn‐ and soybean‐producing counties in the United States over the period 1997- 2022. Using self-reported farmland value data from the Agricultural Census and county-level pollution classifications provided by the Environmental Protection Agency, we employ a difference-in-differences
event-study design—incorporating inverse probability weighting and doubly robust estimators—to estimate the causal effect of regulatory interventions. Our primary analysis contrasts “non-attainment” counties, which failed to meet the National Ambient Air Quality Standards for PM2.5, with those that consistently maintained compliance. We further assess heterogeneous treatment effects by extending our analysis with a triple-difference specification comparing counties with high versus low fertilizer use. Additionally, we employ the recentered influence function to conduct an unconditional quantile analysis across the entire distribution of farmland values. Our estimates indicate an 8.80–8.94% decline in farmland values in “non-attainment” counties in response to the enforcement of PM2.5 standards, suggesting
that the economic costs of the prescribed standards were capitalized into farmland values, particularly in regions with higher fertilizer use. However, this impact was not uniform, with more pronounced effects
observed among counties at the lower end of the farmland value distribution.

Résumé : This paper explores the implications of ecosystemic macroprudential regulations on sustainability in an ecological PK-SFC framework. We first discuss the link between banks and global warming; and present the case for connecting prudential regulation with planetary boundaries. We then report a set of simulations suggesting that in the short run, such ecosystemic prudential regulations could effectively green banks’ balance sheets, credit flows, and curtail brown investment, at the cost, however, of significant short-run losses. In the longer run, the induced green transition appears to set the economy on a more sustainable pathway, to decrease inflationary pressures, and to maintain real GDP at the baseline level, with distributional effects favourable to wage-earners. These results highlight the relevance of ecosystemic prudential regulation to tackle climate change and call for adopting a holistic approach to sustainability policies.

Résumé : Contrary to donor countries’ declarations, actual climate assistance received is deemed incomplete by recipient countries. Without a clear definition or standardized accounting method for climate-related assistance, donor countries have considerable leeway in self-reporting their contributions to the OECD and the United Nations. Several case studies have raised doubts about whether the declared projects genuinely qualify as climate initiatives. In this paper, we assess the climate-relevancy of climate aid projects reported between 2002 and 2018 by donor countries using the OECD-DAC Creditor Reporting System database. First, we estimate the share of projects wrongly reported as climate-relevant through a textual analysis with Python programming and complementary hand-coding. We find that out of the 63,195 projects reported as climate-relevant by donor countries, nearly half (48.6%) were not climate-related. Second, using country-level data for 28 donor countries from 2002 to 2018, we estimate the factors that may affect the miscoding of climate projects. Preliminary descriptive results suggest that budget constraints, governments' environmental preferences and electoral preferences could explain the extent of over-reporting.

Résumé : Conflicts in fragile states disrupt governance, resource mobilization, and service delivery, yet their micro-level impact on local state capacity is under-explored. This paper examines how violent conflicts affect the capacity of local governments to raise revenue and allocate resources for public services, using Burkina Faso as a case study due to its recent political instability and escalating conflicts. We construct a commune-by-year dataset covering all 351 communes over 15 years, combining data on public finance, conflict, and economic activities. A key innovation is the inclusion of planned revenues and expenditures, allowing us to assess how conflicts alter local fiscal expectations and performance. Using event studies and shift-share instruments based on gold resources and prices, we find that conflict-affected communes miss revenue and expenditure targets by 6 and 5 percentage points, respectively. This is driven by drops in locally generated revenues and reduced spending on operations and staff. Investment targets also fall short as expected central government grants fail to arrive, deepening fiscal deficits. The weakened local fiscal capacity lasts long after conflicts subside, highlighting challenges in post-conflict recovery.

Résumé : Enhanced capacities and performance of algorithms enable economic agents to delegate an increasing part of their decisions to algorithms. A distinctive feature of these algorithms is their velocity, i.e. their ability to make a decision at a rapid pace as compared to human decision-making. For a firm, pricing is a key strategic decision that needs to be frequently updated and for which algorithms’ velocity can be profitably exploited. In this paper, we study to what extent the use of a rapid algorithm facing a human decision-maker can be employed as a commitment device by a firm in a pricing context. For that, we consider a theoretical two-period model based on an Hotelling framework. Preliminary results suggest that the market outcome resulting from this setting is characterized by softer competition as compared to a situation in which a firm can only manually adjust its price.

Résumé : La désindustrialisation prématurée de la plupart des économies émergentes et en développement est l'un des faits stylisés les plus frappants de ces dernières décennies. Dans cet article, nous montrons que le choix d'un régime de change fixe accélère ce phénomène. En nous appuyant sur un panel de 146 pays développés, émergents et en développement sur la période 1974-2019, nous montrons que les régimes de change fixes ont eu un effet négatif, significatif et robuste sur la taille du secteur manufacturier - les pays en développement étant les plus touchés par le coût industriel d'un tel régime. L’estimation de modèles de gravité montre que l'impact des régimes de change fixe passe par le canal du commerce. En particulier, ces régimes ont maintenu les pays à faible productivité relative dans un état de dépendance structurelle vis-à-vis des importations de produits manufacturés, au détriment de l'émergence d'un secteur manufacturier local fort.

Résumé: Nous proposons une évaluation de la réforme de l’assurance-chômage mise en œuvre le 1er octobre 2021, qui modifie le calcul du Salaire Journalier de Référence (SJR) servant de base de calcul à l’allocation journalière d’assurance chômage. La modification de cette méthode de calcul est double : la période de référence de calcul (PRC) a été allongée de 12 mois à 24 mois et le calcul se base non plus seulement sur les jours travaillés, mais sur les jours calendaires de la période de référence. Nous mettons en évidence plusieurs effets qui peuvent être résumés par deux résultats principaux. En premier lieu, la réforme a réduit le SJR des allocataires ayant des contrats non contigus durant leur PRC, d’environ 11 euros en moyenne, se traduisant par une diminution importante de leur allocation journalière d’assurance chômage. Par ailleurs, le RSA ou la prime d’activité n’ont pas permis de compenser cette baisse. En second lieu, les effets espérés sur le retour à l’emploi - qui avaient été à l’origine de cette réforme - ne semblent pas s’être produits. Certes, la durée de retour à l’emploi s’est raccourcie pour les allocataires ayant eu un parcours fragmenté, mais les contrats obtenus ne sont pas plus pérennes, que ce soit en termes de durée de contrat ou de nature du contrat de travail retrouvé.

résumé : In this paper, we study the effect of strong pessimism on individuals' willingness to pay for insurance. We provide a new behavioral explanation of one of the most important paradoxes for the economics of insurance. Despite being risk averse, most individuals have willingness to pay for insurance that is lower than the expected loss. We show that the lack of trust in insurance companies produces strong pessimism: the decision maker may believe that the insurer will not honor the contract if a disaster occurs. As a consequence, strong pessimism works in the opposite direction of risk aversion and reduces the demand for insurance.

résumé : This article addresses the growing gap between qualitative data on prices and money in France around World War II, and the available CPI. It gathers archival price data to calculate a new CPI for 1938-1949, incorporating both official and black-market prices. The study demonstrates the adequacy of available sources and the robustness of the new CPI, both in its construction and when compared to contemporary analyses. Three key findings are that France did not experience exponential price acceleration; that dictatorship (1940-1944) was no more effective at price control than democracy (1945-1949); and that the 1944-1945 wage increases had a minor impact on inflation, questioning the price-wage loop explanation of France’s post-war inflation.

Résumé : This paper proposes a decomposition approach for health concentration curves. Decomposing changes in health concentration curves gives additional insight compared to decomposing a single index such as the health concentration index. First, the results would be valid for a comprehensive set of indices. Second, and more importantly, it allows for identifying heterogeneous effects along socioeconomic ranks. We use inverse propensity weighting for the overall decomposition. We use multiple recentered influence function regressions on a grid of points to identify the impact of specific covariates. We weight these regressions by the inverse propensity score of the observations to correct for errors due to departure from linearity. The paper also derives the expressions of the recentered influence functions of the relative and absolute health concentration curves since the literature does not offer the expression of these recentered influence functions. We offer an empirical illustration using information on cigarette consumption from the National Health Interview Survey of 2000 and 2020.

résumé : The contact hypothesis posits that interaction with outgroup members can reduce prejudice and improve intergroup relations. While the overall effects of contact have been found to be positive, some studies have found null or even negative effects. We aim to contribute to the understanding of the scope conditions of contact interventions, by singling out the effects of a common component of all existing contact interventions, namely bilateral discussions. Contact is found to be effective in increasing interethnic trust toward the individuals met during the intervention, in line with previous results from longer interventions. However, the results do not generalize to the collective level. Our heterogeneity analyses fail to find evidence of heterogeneity in the treatment effect.

Abstract : This paper proposes a general framework to measure power in market games: the power of an agent over an outcome is understood as the sensitivity of that outcome to counterfactual variations in the agent's preferences. On the one hand, this allows to generalise the Lerner index of pricing power, overcoming some of its limits and extending it to measure the power of a firm not only over its price, but also over its product type, over its competitors' profit or its power to discriminate. On the other, it allows to analyse power under perfect competition, shedding light on the unequal distribution of consumer sovereignty.

Résumé : Nous étudions les perturbations dues à l’introduction d’une nouvelle technique dans une économie en croissance régulière. Hicks (1974) désigne par traverse la trajectoire conduisant à un nouveau sentier régulier, la nouvelle technique étant caractérisée par le remplacement d’une machine « rassise » par une machine « moderne ». La dynamique dépend des caractéristiques des deux machines. L’analyse de Hicks se fonde sur un modèle néo-autrichien et montre que les conditions d’existence d’une traverse de plein emploi sont restrictives. Nous simplifions et étendons le travail de Hicks et effectuons un parallèle avec celui de Pasinetti (1981, 1993) sur la dynamique structurelle, qui aborde un problème similaire dans un autre cadre théorique. La question des effets d’une innovation technologique sur l’emploi et les salaires remonte au moins à Ricardo (1817), passe au XXème siècle par Schumpeter et les nouvelles théories de la croissance, et reste plus que jamais d’actualité.

résumé :This paper identifies the determinants of OECD Environmental Policy Stringency (EPS) index using a panel of 21 European countries for the period 2009-2019. If there is a large literature on the macroeconomic, political, and social determinants of EPS, the people's attitudes or preferences toward environmental policies is still burgeoning. Thus, the main goal of this paper is to estimate the effects of people's awareness regarding environmental issues on the EPS indicator. Due to the endogeneity of preferences, we have applied an instrumental variable framework to estimate our empirical model. Our most important result is to show that individual environmental preferences do have a positive and significant effect on the level of EPS indicator once the endogeneity bias has been taken into account : on average, a rise in individual preferences of 10% in a country will increase its EPS indicator by at least 1.85%. Our results have important policy implications.

Résumé : The oligopoly equilibrium proposed by Cournot [1838] and the non-cooperative equilibrium presented by Nash [1950a, 1951] display strong similarities. More precisely, it is often considered that the Cournotian notion is a particular case of the general Nashian concept. This paper primarily argues that this conventional wisdom is incomplete and disputable, as Cournot actually raises three relevant points that are absent or implicit in Nash’s papers. First, the strategic rationality is clearly specified as reactive by Cournot, while Nash does not explicitly state that strategies are chosen as ‘best replies’. Second, disequilibrium coordination is tackled by Cournot through a process of alternate replies, while Nash defines a purely static concept of equilibrium. Third, the oligopolistic equilibrium is shown as inefficient by Cournot, while the frequent suboptimality of the strategic equilibrium is not treated by Nash. On a secondary note, this paper shows that the two first mentioned original Cournotian traits were not forgotten in the established corpus of microeconomics, as they were integrated in the making of the strategic equilibrium, sometimes explicitly named “Cournot-Nash equilibrium”, which arose as the main equilibrium concept of the post-Walrasian microeconomics starting in the 1970s.

résumé: Echoing recent policies implemented in Seattle and Portland, we examine perceptions of the fairness of the first-come, first-served (FCFS) rule in the context of discrimination in the rental housing market. We use two original hypothetical survey experiments in which a rental agent is confronted with the discriminatory preferences of his landlord clients. A sample of 2,835 respondents representative of the US population was asked about which choice was the best, from a moral point of view: to allocate rental units exclusively to the non-discriminated group, exclusively to the discriminated group, or to whichever group applied first (FCFS rule). Factorial manipulations included in the design are, in Experiment A, the income effect of implementing the FCFS rule for the rental agent, who risks losing his landlord clients if he/she rents to the discriminated tenants and, in Experiment B, contextual effects (peer effects and social norms aligned with or divergent from the FCFS rule). Consistent with the literature, we find that the FCFS rule ranks high among other normative principles, but that its income impact has a causal effect on the support it receives from respondents. We also find that both peer effects and social norms have a causal effect on the support for the FCFS rule, with social norms having a stronger effect. Finally, we find that the respondents who are likely to experience discrimination are the least likely to support the FCFS rule.

résumé: La présentation s'appuie sur deux études. D'une part, il s'agit d'une étude empirique fondée sur une expérience de choix discrets avec près de 600 agriculteurs vietnamiens visant à mesurer comment des facteurs de marché et des facteurs hors marché peuvent influencer leurs préférences en matière d'adoption de pratiques d'agriculture biologique. Nos résultats suggèrent que les contrats de vente (avec des prix flexibles ou garantis), la formation et le soutien technique des agriculteurs, la présence des agriculteurs biologiques et, en particulier, celle des agriculteurs leaders officiels en agriculture biologique sont des facteurs encourageant les agriculteurs à se convertir à l'agriculture biologique. D'autre part, en nous intéressant uniquement au facteur de leadership, nous proposons une modélisation théorique à 2 agents, un agriculteur leader et un agriculteur suiveur (follower). Le leader, possédant une information privée sur la productivité de la technologie de production biologique, décide en premier, la part de sa surface de terre consacrée à la production biologique (le reste étant en agriculture conventionnelle). Le follower observe cette action et décide à son tour son engagement dans cette production. Les agriculteurs (leader et follower) peuvent coopérer sur la base d'une négociation à la Nash. Ce modèle théorique est par la suite confronté à des données expérimentales collectées également au Vietnam. Nos premiers résultats tendent à valider les conclusions de notre modèle théorique.

résumé :
This paper investigates the effects of dissent in ECB meetings on asset prices and the formation of policy expectations, based on a novel index of dissent. Using intraday data, we exploit a particular feature of the ECB communication framework for identification: policy decisions are announced in a press release, but dissent is revealed during the press conference later that day. We document that dissent – both expansionary and restrictive – has a negative effect on stock prices and acts as an uncertainty shock. We provide evidence that expansionary dissent pushes down ex ante policy expectations and contributes to more positive monetary surprises.

résumé :
We study how global value chain participation causally affects productivity at the firm level. We utilize an extensive dataset encompassing firms from countries of different income levels over the period 2006-2021, together with matching approaches to control for endogeneity. Our primary finding underscores that the simultaneous coordination of importing and exporting activities within a single firm leads to an increase in labor productivity. Positive effects on TFP are significant only within the subgroup of firms in the less developed countries and those operating in low-tech industries. Increased capital intensity appears as a plausible explanation of labor productivity gains. We also find higher innovation propensity, quality enhancements, and labor-cost reductions for two-way traders as channels through which GVC participation influences firms' technical change. The lower responsiveness of TFP in advanced countries can be explained by the different nature of technical change for firms operating closer to the world technology frontier.

Abstract : Nous définissons le concept de Couverture Politique Opportuniste de la Banque Centrale (CPOBC) qui correspond à une modification opportuniste de la popularité des partis politiques imputable à la couverture médiatique de la politique monétaire. Plus précisément, nous supposons que le traitement médiatique de la politique monétaire dans la presse a un impact significatif sur la popularité des partis politiques nationaux avant les élections. Afin d’étudier l’existence de ce concept, nous mobilisons des côtes de popularité mensuelles de 6 partis politiques allemands sur la période allant de janvier 2005 à décembre 2021. Par la suite, nous mesurons la couverture médiatique à travers une analyse textuelle sur plus de 26.000 articles de presse provenant de 6 journaux allemands. Enfin, nous estimons des fonctions de popularité pour ces partis politiques allemands au sein desquels nous introduisons nos mesures textuelles en interaction avec une variable muette prenant la valeur 1 le mois précédent une élection. Notre analyse met en évidence l’existence de ces CPOBCs en Allemagne le mois précédent une élection fédérale ou le mois précédent une élection européenne. Ce résultat est robuste à l’utilisation d’un modèle SUR, la définition de périodes pré-électorales différentes, la mise en place de deux analyses de sentiment, l’utilisation de données issue de Google Trends et la prise en compte de l’intérêt de l’opinion publique pour les membres de la BCE. De plus, il semble que l’existence des CPOBCs dépend de l’idéologie des journaux étudiés.

Abstract : In this paper, we trace the rise of heterogeneous household models in mainstream macroeconomics from the turn of the 1980s to the early 2000s, when these models evolved into an identifiable and consistent literature. We show that different communities across the US and Europe considered heterogeneous agents for various reasons and developed models that differed in their theoretical and empirical strategies. Minnesota economists primarily focused on incorporating stochastic heterogeneity into general equilibrium models. Other researchers refined growth models or tried to find alternatives to the permanent income hypothesis, leading them to explore more structural heterogeneity. We also document the computational challenges that some of these communities faced, how they gradually became aware of each other's work, and how they faced criticisms from macro- and microeconomists, many of them trained in European countries and dissatisfied with the theoretical and empirical aggregation strategies underlying these models.

Abstract: Empirical evidence shows that men and women make different educational choices and hold different types of occupations. In this paper, we study the case of medical studies in France: a very competitive field in which there are today more women than men and where high gender imbalances in terms of medical specialty choices are observed. We investigate the determinants of the gender gap of specialty choices that takes place at the end of the 6th year of medical studies after taking a national exam that rank the students allowing them to sequentially choose a specialty from the available residency positions. We confirm that women perform less and thus have a more constrained specialty choice set than men. The taste for competition largely explains this gender gap. We also show that even when facing the same choice set, women choose different specialties than men and that is mainly because women have different tastes for specialties amenities.

Résumé: Most macroeconomic models, both fully structural models as well as SVAR models, view economic outcomes as the product of a combination of endogenous and exogenous dynamic forces. In particular, the exogenous forces are generally modeled as a set of linearly independent dynamics processes. In this paper we begin by showing that this dual dynamic structure is sufficient to identify the entire set of structural impulse responses inherent to any such model. No extra restrictions are necessary. We then use this observation to suggest how it can be used to evaluate common SVAR restrictions (impact restrictions, long-run restrictions and proxy-VAR), as well as help transpire the role of cross-equation restrictions inherent to more structural models.

Résumé : In this paper, we propose a new threshold model to deal with the asymmetry and leverage effect in the volatility of financial time series. Our model generalizes the classical threshold stochastic volatility model. By introducing a new flexible and smooth regime-switching mechanism, we avoid the sudden jump in the log-volatility imposed by the classical model. More precisely, we propose a new threshold model that we call Buffered Threshold Stochastic Volatility (BTSV) model. After the definition of our model, we derive a sufficient condition for the strict stationarity of the model. Then, we develop a Sequential Monte Carlo method to estimate the parameters. Next, we analyse the performance of the proposed method through a simulation study. Finally, we apply our new methodology to model the Honeywell International Inc and Standard and Poor Composite 500 stock market indices. This empirical analysis shows that BTSV model is a competitive alternative for the asymmetry modelling in financial returns analysis.

résumé :
Depuis le milieu des années 1990, le primat de la baisse des dépenses publiques et les politiques d’offre fondées sur le contrôle des salaires et la réduction des coûts de production se sont imposés, accentuant les critiques à l’égard de la fiscalité. Le résultat de ce mouvement est particulièrement visible du côté des entreprises dont les prélèvements obligatoires, après avoir augmenté au cours de la période 2009-2013 connaissent depuis une réduction sensible et rapide qui contraste avec la hausse ininterrompue et marquée des taux des ménages (Plane & Sampognaro, 2015). En dépit de cette situation, les différentes organisations professionnelles françaises, plus que celles d’autres pays de l’OCDE, ont contribué à renforcer ce mouvement en arguant du poids de la fiscalité des entreprises, en général, et des impôts dits « de production », en particulier, qui figurent parmi les plus élevés d’Europe (DG Trésor, Rapport économique, social et financier - PLF pour 2020, p. 174).
Les entreprises, notamment au niveau national via leurs fédérations représentatives, se plaignent de la charge que la fiscalité locale fait peser sur leur bilan et marges financières. La fiscalité locale est présentée comme un frein au développement et surtout à la réindustrialisation du pays sans qu’il y ait de mise en perspective avec les biens et services collectifs que ces impositions locales permettent de financer...

Résumé : Fuel taxes being very unpopular, most environmental policies in the automobile sector consists in subsidies, standards, or feebates. A major drawback to the effectiveness of such policies is that they only affect new cars. However, the interaction between first-hand and second-hand markets has not been documented yet. This paper investigates how environmental taxes on new cars affect prices in the used-car market. Focusing on the French feebate on new vehicles, I use a unique data set from the leading French car-selling platform. I find a statistically significant effect of taxes on the prices of used cars. This pass-through to used car prices fades after one to two years. On the contrary, I do not find any effect of subsidies on low-emission vehicles on used car prices. These results indicate that sellers of relatively young polluting cars manage to pass the taxes they paid at registration to buyers in the used car markets. They also indicate that subsidies do not significantly decrease prices in second-hand markets. More generally, these preliminary findings bring new perspectives to the evaluation of the effectiveness and distributive effects of environmental policies in the automobile sector.

Résumé : We exploit the exogenous variation in the timing and intensity of storms in island countries to estimate the storms' effect on the extent of democracy. Using a rich panel dataset spanning the period 1950–2020, our difference-in-differences estimations, which allow multiple treatments over time, indicate that storms trigger autocratic tendencies in island countries by reducing the Polity2 score by about four percent in the following year. These findings resonate with our simple dynamic game-theoretical model, which predicts that governments move towards autocracy by placating citizens with post-disaster assistance in response to citizens’ insurgency threat in the absence of relief, giving rise to the political regime of “storm autocracies”. Our results survive a battery of robustness analyses, randomization tests, potential spatial biases, and other falsification and placebo checks.

Résumé : The commitment of companies to the transition process to a low carbon, circular and sustainable economy in France relies, alongside other regulatory instruments, on mandatory public disclosure of information. Several laws have been passed in the 2000s that contribute to increase both the quantity and verifiability of available information. In this ongoing study, we provide a qualitative analysis of companies environmental and climate reporting in the lights of developments in disclosure legislation. We detail an NLP pipeline used to create and analyze a dataset of about 120k pages of publicly available reports from 27 French companies over 12 years. We highlight that, despite the legislation influenced companies discourse towards greater compliance, firms have heterogeneous practices regarding public disclosure of information.

Résumé : Renewable energy communities involve various agents who decide to jointly invest in renewable production units and storage. This paper examines how these communities interact with the energy system and can decrease its overall cost. First, we show that a renewable energy community cancontribute positively to welfare if the electricity produced by the investment is consumed close to its place of production, i.e. if the community has a high degree of self-consumption. Second, our analysis identifies the condition on prices and grid tariffs to align the community's interest with welfare maximization. We also show that some of these grid tariffs do not have a negative impact on non-members of the community and could therefore limit potential distributional issues. Third, we argue that various internal organization of the renewable energy communities are feasible. The internal organization impacts the distribution of benefits among members but not the global efficiency of the community.

Résumé: We investigate whether the International Criminal Court (ICC), launched in 2002, effectively deters ruling leaders and criminal groups under its jurisdiction from engaging in egregious violence against civilians. We exploit killings data from a panel of 176 countries over the period 1989-2019 and estimate Interactive Fixed Effects models to control for the endogeneity of the ratification process. ICC jurisdiction has negative effects on violence committed by non-governmental forces in high-risk countries, previously characterized by civil violence and weak institutions. The evidence regarding violence by governments is more mixed, a pattern that is consistent with the institutional fragility of the Court.

Résumé : This study contributes to the literature seeking to test the pollution haven’s hypothesis (PHH), by focusing on the influence of environmental policy on the location’s decision of cross-border Mergers and Acquisitions (M&As). To this end, we build an original database for M&As for 34 host countries, 100 source countries, 54 sectors during the period 1995-2015. An important contribution of the study is to implement a structural gravity approach that accounts for omitted bias, border effects and simultaneity bias. This is the first study applying this method to bilateral FDI at the sector level. Our aim is to test whether laxer environmental regulation may favour inward M&As in general or in more polluting sectors in particular. Our preliminary results confirm that more stringent environmental policies make countries less attractive to foreign investors planning to invest through M&As. This especially the case, as expected, when sectors of destination contaminate more than the average as measured by greenhouse gases emissions per employee. Finally, the effect of more stringent environmental policy does not significantly affect the amount invested (intensive margin).

Résumé : Cette présentation a pour objectif de faire le point sur le Mécanisme d’Ajustement Carbone aux Frontières (MACF) dont la Commission Européenne a décidé le démarrage sous forme transitoire à partir de 2023 dans le cadre de son Green Deal. La présentation replace dans un premier temps le MACF dans le contexte plus large de la politique climatique de l’UE, en soulignant notamment comment il s’inscrit dans l’évolution de long terme du marché du carbone européen, l’EU-ETS. Dans un second temps, les modalités du MACF, telles que connues à ce jour, sont présentées et analysées. Dans un troisième temps, la capacité du MACF à faciliter l’accélération de la décarbonation de l’économie européenne en s’appuyant sur l’EU-ETS est discutée et une première évaluation qualitative est proposée.

Résumé: Ce papier fournit une nouvelle mesure de capital humain qui s’appuie sur les enquêtes PISA et PIAAC, et les années moyennes de scolarité. La nouvelle mesure est une moyenne pondérée par cohorte des scores PISA antérieurs (représentant la qualité de l'éducation) de la population en âge de travailler et des années moyennes de scolarité correspondantes (représentant la quantité d'éducation). Contrairement à la littérature existante, les poids relatifs de chaque composante ne sont ni imposés ni calibrés mais directement estimés. Le papier constate que l'élasticité du stock de capital humain par rapport à la qualité de l'éducation est trois à quatre fois plus grande que par rapport à la quantité d'éducation. La nouvelle mesure a un lien étroit avec la productivité, le potentiel de gains de productivité étant beaucoup plus important quand ils résultent d’une amélioration de la qualité plutôt que de la quantité du capital humain. L'ampleur de ces gains potentiels de PGF est comparable à une amélioration standardisée similaire de la réglementation des marchés de produits, mais les effets se matérialisent avec des délais beaucoup plus longs. Le papier montre, à travers l'exemple de l'enseignement pré-primaire, comment simuler l'impact d'une réforme particulière de la politique éducative sur le capital humain et la productivité.

Using survey-based monthly oil price expectations, we measure ex-ante oil risk premiums for 3- and 12-month horizons over a period of thirty years. We show that these premiums, which are particularly appropriate to analyzing investors’ decision-making, are nearly uncorrelated with the ex-post premiums usually employed in the literature where the expected price is replaced by the ex-post realized price. We consider a simple portfolio choice model from which each risk premium can be expressed as the product of the risk price and the expected variance of oil returns, both of these components depending on time and horizon. A two-horizon model of risk premiums, where the risk prices are represented as stochastic unobservable components and the expected variances as weighted averages of actual and past instantaneous variances, is estimated using the Kalman filter methodology. We find that the representative investor is mostly risk seeking at the short horizon and mostly risk averse at the long horizon. The prevalence of risk-aversion when oil market is bullish and of risk seeking when it is bearish is consistent with the predictions of the prospect theory. A dominant upward sloping term structure of ex-ante oil risk premiums is evidenced over our extended period. Our oil risk prices are shown to depend on economic and oil market-related factors.
