        Abstract: In the sense of Spence (1973), education sends a signal to the labor market which helps to reveal the ability of former students. Delayed graduation is usually perceived as a negative signal, leading to lower wages and employment rates. This paper tests for the presence of heterogeneous effects of the signal sent by delayed graduation in higher education (post-high school diploma). These effects are measured on the rate of employment and average wages at individuals’ entry into the labor market. I analyze if the heterogeneous structure of the effects is conditional on individuals’ characteristics such as diploma, social origin, or gender. I use the generalized random forest algorithm with an instrumental setting to estimate individual Conditional Average Treatment Effects. In line with the literature, I find a negative effect of delayed graduation on the rate of employment. However, this effect is heterogeneous across individuals, ranging from -60% to -10%. As expected I find a subgroup with negative treatment effects on average wages, but also individuals benefiting from delayed graduation with a positive treatment effect. The individual treatment effects on monthly average wages range from -350€ to around 200€. Gender does not affect the heterogeneous effects on the rate of employment but does influence the effects on average wages. Study duration and field affect both indicators. The social origin (parents’ occupation) also plays a crucial role in determining the individual treatment effect on the rate of employment and average wages.

        Abstract: The International Criminal Court (ICC) was launched in 2002 with the purpose of fighting impunity and deterring the commission of international crimes. In this paper, we investigate whether the ICC effectively deters ruling leaders and criminal groups under its jurisdiction from engaging in egregious violence against civilians. We exploit civilian killings data from a panel of 176 countries over the period 1989-2019 during which 123 countries incrementally decided to ratify the Rome Statute and recognize the jurisdiction of the ICC, while others never did. Due to the strong suspicion of endogeneity of the ratification process, we rely on flexible panel data models with interactive fixed effects to account for potentially complex country-specific trends. We find no evidence of any deterrence in the full sample of countries. However, we find that the probability and intensity of civilian killings by non-governmental forces decreases quite substantially after ratification in high-risk countries, i.e. countries that were marked by civil violence and weak institutions in the 1990s. Conversely, civilian killings by governmental forces appear unaffected by the ICC even in high-risk countries, a pattern that is consistent with the institutional fragility of the Court.

        Abstract: An increase in the legal limit of THC has de facto opened the market for light cannabis in many European countries. CBD products are attractive to consumer given their content of CBD which is a non-psychoactive compound. Despite the hype of this market, there is a substantial lack of information on consumers’ attitudes and motivations toward CBD products. Through an ad-hoc online survey, the first cross-national study was performed to investigate the characteristics of French and Italian users of light cannabis. The survey moves from a previous data collection conducted in Switzerland identifying the mechanisms behind the substitution effect and consumption preferences and focusing on flowers as the main mode of consumption. The results indicate that one out of three CBD users substitute other substances. The reduction in consumption is more prevalent for regular cannabis, tobacco and medications (about one out of 6 users), than for alcohol. CBD use helps to reduce alcohol consumption mostly among older males with a long experience with CBD. Whereas sublingual oils are more likely to be used to substitute medicines, smoking flowers is the favourite mean of substitution for tobacco and regular cannabis. Consumers who substitute regular cannabis show a preference for a diversification of varieties, which does not occur among those who substitute tobacco. Overall, the motivations behind consumption determine differential preferences across CBD consumers. This calls for a rethinking of the most adequate distribution channels for specific CBD products based on the purpose of use. The goal should be to maximize access by providing a differential degree of quality and taxation across the different supply channels based on the expected externality.

        • Adham JaberESG performance and fiscal sustainability: An empirical assessment in advanced economies

        Abstract: We document the Environmental, Social and Governance (ESG) performance impact on fiscal sustainability. Using data on 24 OECD countries from 1998-2015 we assess the impact of extra-financial performances, created using a two-step Principal Component Analysis, on the fiscal reaction function and the fiscal space. First, we find robust evidence that countries under fiscal pressure tend to underperform in ESG and that ESG performance can be a burden on fiscal policies. Second, we compute a time-varying fiscal space and show that overall ESG performance increases fiscal space. Methodologically, we show that complex fiscal space values resulting from solving the model provide crucial information in assessing fiscal sustainability and they should not be ignored. For this purpose, we provide 3 different scenarios to deal with complex numbers in an empirical framework.

          Does Trust Influence Social Expenditures? Evidence from Local Governments

          Discutant(e) : Marc Arthur Diaye (Prof. des Universités, CES Paris 1)

          Abstract : We document that trust has a positive impact on the generosity of welfare spending. Our analysis relies on a unique dataset including detailed budgetary data of more than 2,000 Italian municipalities. Compared wit previous contributions based on cross-country data, our approach reduces the risk of omitted variable bias and measurement errors. Furthermore, drawing on Italy’s rich political history, we are able to use an instrumental variables strategy that addresses the possible endogeneity of trust.

            Bones, Bacteria and Break Points:The Heterogeneous Spatial Effects of the Black Death and Long-Run Growth

            Noel Johnson, U. George Mason (en coll. avec Remi Jedwab et Mark Koyama)

            Discutant : Hillel Rapoport, PSE

            Abstract : The Black Death killed about 40% of Europe’s population between 1347-1352. Historical studies suggest that this mortality shock played a major role in shifting Europe onto a path to sustained economic growth. Using a novel dataset that provides information on spatial variation in plague mortality at the city level, as well as a range of controls and various identification strategies based on the spread of the epidemic, we explore the short-run and long-run impact of the Black Death on city growth. We find evidence for aggregate convergence. On average, cities recovered their pre-plague population within two centuries. However, there was considerable heterogeneity in the response to the shock, hence local divergence. The Black Death led to an urban reset: cities with better geographical and non-geographical endowments did relatively well, while other cities collapsed. In particular, our results emphasize the importance of trading networks in explaining urban recovery. Furthermore, the Black Death led to the creation of new cities in areas that were relatively less urbanized before it hit. Our analysis thus suggests that the Black Death may have permanently affected the spatial distribution and aggregate level of economic activity, potentially contributing to long-run growth in Europe.

            Warfare’s ecological footprint: A Synthetic Control (SCM) approach with data from the Falkland Islands (avec S. Panel)

            Antoine Pietri (Ministère de la Défense) (en coll. avec S. Panel)

            Discutant : Luigi Moretti (CES, Paris 1)

            Warfare has been found to have detrimental impacts on biodiversity due to its long-lasting economic and social consequences. Yet, much less is known about the amount of biodiversity loss directly resulting from the use of military technology. This paper analyzes the environmental consequences of one of the largest aerial and naval conflict of the late 20st century, namely the 1982 Falklands War. The fact that the conflict was unrelated to environmental issues, did not spill over to neighboring countries, and did not relapse afterwards, allows us to circumvent identification issues that commonly affect comparative studies on the ecological footprint of warfare. As an indicator of the marine ecosystem status, we analyze population trends of king penguins breeding at the Falkland Islands and six other sub-Antarctic colonies over a thirty-year period (1965-1995). We use the Synthetic Control method – a method that was explicitly designed for small-N comparative studies – in order to build ``counterfactual'' Falkland Islands whose characteristics closely resemble those of the Falklands before the war and allows us to approximate the trends of the outcome variable in the absence of the war. We find tentative evidence that the war led to a short-term increase in king penguins’ population growth. However, this effect is offset by a higher rate of breeding failures during the war, resulting in a delayed adult population decrease. We find no evidence of lasting effects.

            Résumé : Cet article propose une analyse des deux moteurs du développement territorial : les processus de production et de gouvernance. Il examine leurs caractéristiques, leur fonctionnement et le rôle qu’ils jouent dans la mise en place des mécanismes de développement. Les modalités de création des innovations territoriales de différentes natures (technologiques, organisationnelles, sociales et institutionnelles) sont également étudiées. Le texte commence par un bilan de littérature et d’expériences sur les notions de gouvernance et de production au niveau territorial, suivi par une analyse de leurs modalités de fabrication des innovations territoriales. Pour finir, les mécanismes du développement territorial sont décrits sous forme de schémas, en s’appuyant sur trois options possibles : la loyauté ou la coopération, la prise de parole ou la concurrence, l’exit spatial ou la délocalisation.

            Civic Engagement and State Provision of Public Goods: An Experiment

            Abstract:  Effective states solve the problem of financing the provision of public goods by mandating contributions in the form of taxes and imposing penalties for non-compliance. However, government might tax and provide public goods accountably only if enough citizens are civically engaged. We study the voluntary cooperative underpinnings of the accountable sanction-imposing state by conducting a two-level public goods experiment in which civic engagement can build a sanction scheme to solve the first order public goods dilemma. We find that when civic engagement costs are low relative to the benefits of public good provision, the overall dilemma problem is tractable, though it is never privately profitable to civically engage. In addition to a small average cost-to-benefit ratio, local social interaction among participants boosts cooperation.

            Abstract : We provide a new measure of work motivation and show that motivation shapes the effects of team incentives and observation by peers on performance. In particular, we measure motivation to work hard as the deviation from the money-maximizing benchmark in a real-effort experiment. While we find that average output increases in response to team incentives and observation, we find that highly motivated workers do not respond. The reason is that highly motivated workers already work hard and increasing effort even further is very costly to them.

            Elections systems, the beauty premium in politics, and the beauty of dissent

            Heinrich Ursprung (U. Konstanz, Germany) ( en coll. Niklas Potrafke)

            We ask three questions. First do election systems differ in how they translate physical attractiveness of candidates into electoral success? Second, do political parties strategically exploite the "beauty premium" when deciding on which candidates to nominate and third do elected MPs use their beauty premium to reap some independance their party? Using the German election system that combines first past the post election with party list proportional representation our results show that plurality élections provide more scope for translating physical attractiveness into electoral success than proportional representation. Whether political parties strategically use the beauty premium to optimize their electoral objectives is less clear. Physically attractive MPs, however, allow thenselves to dissent more often, i.e. they vote more often against the party line than their less attractive peers.

            Moral disagreements in Business. An exploratory introduction 

            Marian Eabrasu, South Champagne Business School

            Springer, sept 2018

            Abstract: This book disassembles the moral assessment of business practices into its constituent parts to identify and clarify the four key concepts that form the basis of important moral disagreements in business: ‘personhood,’ ‘ownership,’ ‘harm,’ and ‘consent.’ ‘Moral bottom lines’ are those fundamental concepts in business ethics that ultimately account for our most resilient moral claims and unsurpassable convictions, and exploring them provides essential insights into the grounds on which we disagree in business ethics. This analysis is useful for students in business school looking to understand fundamental moral disagreements in business and for practitioners interested in connecting practice with their own moral intuitions. The book also challenges scholars of business ethics by arguing that we can reduce business ethics disagreements to these four issues.

            The Politics of Experimentation: Political Competition and Randomized Controlled Trials
            Michael T. Dorsch, Central European University. Budapest (co-auteurs : Cristina Corduneanu-Huci et Paul Maarek)

            This paper provides an analysis of the political factors that might affect the location of Randomized Controlled Trial (RCT) experiments in public policy. We first review some of the potential supply and demand-side channels of site selection, and then focus on the role of domestic political competition in determining when decision makers are interested in policy learning. We argue that more competitive political environments, where incumbents face a higher probability of losing power, strengthen the incentives of bureaucrats and politicians to run RCTs. We also introduce a unique data set on development RCTs that we have compiled. Over a cross-national panel and a panel of Indian states, we find that RCTs testing accountability interventions or involving the government as a partner are more likely to occur in politically competitive jurisdictions. Other types of field experiments are less sensitive to context. Results are statistically robust to estimation with instrumental variables, alternative specifications, and on larger datasets of development RCTs. We suggest that the political context matters for when, where, and with which partners policy RCTs happen.
