Abstract : "Latent profile analysis (LPA) is carried out to identify different behaviour of firms in the European Union Emissions Trading System (EU ETS). The goal is to identify profiles based on firms' transaction activity and not considering other characteristics, thus without any a priori bias on the type of behaviour a firm may have. This is especially relevant in the current context of suspicion of speculation in the market. The aim is to contribute to the debate on the potential detrimental role played by certain actors. Firm transaction behaviour is summarised using centrality and popularity indicators stemming from network theory. Estimated indicators include degree, strength, betweenness and eigenvector centralities, harmonic closeness and PageRank. Based on these indexes, LPA is performed to investigate the existence of different firm profiles and identify them. Firm characteristics are then added as covariates to explore the determinants of belonging to a certain group. Visualisation of the transactions network along with the estimation of indicators reveal that the network is highly polarised around a handful of financial firms that play the role of intermediary for compliance firms. The LPA further leads to the identification of three relevant profiles, with notably a "popular" profile characterised by extreme centrality values. Firm regulatory status and sectoral activity seem to be playing a significant role in determining profile assignment."

Abstract: In this note, we investigate the effectiveness and the optimality of fiscal policies in the strategic bilateral exchange framework of Gabszewicz and Grazzini (JPET, 1999). We notably propose to test the robustness of the following result: endowment taxation with transfers can implement a first-best allocation in Cobb-Douglas, linear and CES strategic bilateral trade. Through an example in which the preferences of traders are represented by quasi-linear utility functions, we show that endowment taxation with transfers implements a Pareto-optimal allocation, while taxation without transfer does not. Indeed, the optimality of endowment taxation with transfers is robust for a larger class of utility functions, including the quasi-linear utility function, which is often used to represent the preferences of agents in public economics.

Abstract: In this paper, we focus on an overlooked determinant of business cycle synchronization namely the migration. We consider the African countries as sample over the period 1990-2019 subdivided in six periods of each five years. Rely on pooled OLS IV estimates, wefind a positive effect of migration intensity among African and ECOWAS countries on their output co-movement. Second we show that remittances channel usually tested in the literature also enhances synchronization.

Abstract : This paper contributes to the literature on fiscal policy and inflation. In particular, it estimates the effect of fiscal rules on inflation for a panel of 79 countries over the period from 1985 to 2021. To achieve this end, we use propensity score methods in order to deal with potential endogeneity issues. Our estimates show that the adoption of fiscal rules leads to a decline in inflation in the whole sample. Nevertheless when splitting according to different characteristics, we are unable to conclude for advanced countries and for countries whose central banks are not credible. These results are robust to different specifications.

Abstract : This paper examines the acceptability of different public policies aimed at limiting negative externalities. The paper explores the impact of experience from a policy trial, cultural worldviews, and the policy acceptability of bans and taxes. The authors conduct a laboratory experiment with participants facing a negative externalities game and introducing public policies in the form of taxation and quantity regulation policies. The participants are asked to vote for or against the implementation of the policy after experiencing a policy trial. The results indicate that acceptability varies across different policy instruments and that experience from a policy trial can influence acceptability. The study also finds that cultural worldviews impact the acceptability of different policies.

Abstract:
In this study, we use a lab experiment to investigate individuals' reactions to defeat. In an attempt to understand if men dislike competing with women, this study analyzes men's willingness to compete again, against a high-performing woman. Using a strategic method, our research seeks to elicit men’s and women’s behaviors in a repeated competition context. Meanwhile, we investigate different reactions when giving the participants hypothetical information about the points gap with their opponent. Our results show that men are more reluctant to compete against a man (than a woman) when being defeated by a large point gap. Women, on the other hand, do not base their decision to compete again on the gender of their opponent.

Abstract : Defining a fair and transparent measure of carbon leakage risk is primordial to effectively tackle carbon leakage without undercutting the impact of climate policies. This paper proposes a new approach to measure the risk of carbon leakage, and applies it to the steel and cement industries. The micro-founded hypothetical monopolist test (or SSNIP) is applied at a country-product level to delineate the relevant market for each of these industries. A gravity model is used to estimate technical substitution elasticities at the product level, from which own- and cross-price elasticities are derived and used as inputs in the hypothetical monopolist test. The results from this analysis point to steel markets being delimited at the national level, while the relevant market for cement seems to include several countries, including some outside the EU for clinker.

Abstract: The aim of this paper is to investigate the links between strategic metals - which are crucial in the transition to a low-carbon economy - and foreign investment flows. To this end, we consider a panel of 20 strategic metals and 110 countries over the 1997-2020 period. Using a battery of panel data estimations to ensure the robustness of our results, we find that there is no FDI-resource curse for the strategic metals production. Strategic metals have a very strong force of attraction on foreign investments, which has many implications for both the economic development and geopolitical weight of the different producing countries.

Abstract: "This paper analyses the impact of the low-interest rate environment on the profitability of 37 life insurance companies operating in France over the 2009-2018 period. Our empirical analysis suggests that Monetary Policy has a significant impact on profitability. This result holds after controlling for macroeconomic and financial conditions and different life insurers-specific characteristics. Accounting for the heterogeneity of life insurers, the paper sheds light on the asymmetrical impact for smaller companies. The article further examines the influence of the solvency position of life insurers on profitability and issues policy recommendations for regulators to mitigate the influence of the low-yield environment, particularly on smaller insurers."

Abstract: We construct indicators of the attention paid by US monetary policymakers to the international situation. We apply natural language processing techniques to minutes of the Federal Open Market Committee. We discuss the channels through which foreign economic conditions can impact US monetary policy and their relative importance in Fed discussion. By adding these text-based indicators to a standard forward-looking Taylor rule, we derive a quantitative measure of the external influences on decisions made by the US Federal Reserve. Our results show that when international matters are discussed at greater lengths, the Fed is more accommodating than what would be suggested by the Taylor Rule.

Abstract:
This paper sheds new light on law and finance in the post-crisis period by studying the impact of insolvency regimes on non-performing loans. Using a novel database on European transparency exercise data over 2015-2020, our results, based on fixed effects panel specifications, provide an innovative view of the impact of economic and institutional factors on the quality of banks’ loan portfolios. They confirm and capture more precisely the influence of economic cycle indicators like the GDP growth rate and unemployment and shed new light on the importance of the insolvency framework in discussions about loan quality. Unlike prior studies, the specification used, which varies destination at bank level, makes it possible to disentangle the impact of macro factors, institutional quality and bank characteristics. The impact of insolvency regimes, is found to be favourable for bank non-performing loans and, more broadly, for financial stability.

Abstract :
L’objectif dans ce papier a été de remédier au manque de la littérature en analysant le rôle de la migration bilatérale dans la stabilité du taux de change bilatéral et de dériver du modèle de régression des indices de Zone Monétaire optimale (ZMO) initialement développés par Bayoumi et al, 1997 pour un élargissement de la zone Union Economique Monétaire Ouest Africaine (UEMOA). Les résultats mettent clairement en évidence le rôle majeur joué par la migration bilatérale dans la stabilité du taux de change bilatéral et des indices qui diminuent au fil du temps pour les pays membres et non membres de la zone UEMOA. Ce qui traduit des signes de convergence mais tous les pays de la Zone Monétaire d’Afrique de l’Ouest (ZMAO) ne peuvent pas intégrer la zone UEMOA ou du moins participer à la monnaie unique car l’asymétrie est encore élevée pour certains pays.

Abstract :
This paper revisits the crucial issue of global imbalances and focuses on the determinants of the current account gaps between eurozone Member States. We conduct robust estimations of the current account balances for a panel of ten euro area economies and construct a measure that allows us to diagnose why some countries have started to diverge from the eurozone mean in the last two decades. Our findings show evidence of remaining differences in countries’ economic development, meaning that real macroeconomic convergence has failed in the zone. Price and cost competitiveness, as well as fiscal balances, have also participated in this growing macroeconomic divergence. Overall, while the European authorities cannot influence the part of the gaps due to demographic factors, the role of fiscal redistribution and investment at the euro area level could help achieve macroeconomic convergence..

Abstract:
Variable and renewable energy (VRE) sources lie at the core of the European energy decarbonating and independence strategy. A larger share of renewable generation requires flexibility options to cope with intermittency and production uncertainty. Among the flexibility solutions, energy storage has become increasingly interesting because of its versatility and recent high costs reductions. In this paper, we investigate the development potential of energy storage solutions as future dispatchable assets to compete with existing fossil fuel power plants. We propose a novel analysis in the light of the recent energy and geopolitical crisis, which might help the understanding of where Europe stands today in its path towards energy independence. We use a stochastic competitive optimization framework, calibrated on the current Western Europe power system, to derive the market value of new storage technologies and their impact on the price structure. We estimate the long-term equilibrium of flexibility capacities under different renewable horizons, CO2 prices and vehicle-to-grid (V2G) trajectories. We subsequently analyze incremental revenues and costs due to the presence of storage on the wholesale market and their distributions among renewable firms, conventional power plants and electricity consumers. We find evidence that, without additional support policies, the development of stationary storage remains moderate and located in a few countries of interest, mainly because of fierce competition from gas facilities. The contribution of V2G is predominant as it accounts for a large part of the new storage capacity. Finally, we highlight a detrimental effect of new storage on the revenues of fossil fuel power plants and a significant and positive effect on solar and wind revenues, making the case for a smart design of support public policies that integrates the transfers storage operates between market firms.
