SUMMARY:Internal Seminar: Ubaid ur Rehman
DESCRIPTION:U.S. Monetary Policy Spillovers to Emerging Equity Markets \nThis paper examines the transmission of U.S. monetary policy shocks to stock return volatility in emerging economies. It develops a small open economy DSGE framework as a proof of concept for the propagation mechanism\, showing how foreign monetary shocks can affect exchange rates\, borrowing conditions\, inflation\, and real activity\, with implications for equity market volatility. The empirical analysis uses daily return data for 14 emerging market stock indices and models volatility with a GJR-GARCH specification. The baseline results indicate that U.S. monetary policy developments are associated with significant changes in emerging market volatility\, while the asymmetric specification allows for differential responses across tightening and easing episodes. The analysis is then extended to incorporate high-frequency monetary policy surprises\, providing additional evidence that market volatility responds not only to policy changes themselves but also to the information content of U.S. monetary policy announcements. \nSalle des Congrès at MIR.

SUMMARY:Internal Seminar: Eddy Zanoutene
DESCRIPTION:Title:\nDistortions for Nothing – Optimal Taxation of (Un)distributed Profits \nAbstract:\nWe study the optimal taxation of corporate and dividend income when entrepreneurs can use retained earnings to reduce their tax burden. We show that eliminating dividend taxes while increasing the corporate income tax (CIT) to keep investment unchanged raises total tax revenue. Our simulations suggest net revenue gains of 0.1-0.4% of GDP. In an infinite-horizon model\, the optimal policy sets dividend taxes to zero in every period. As the discount factor approaches one and when the planner values only workers’ welfare\, the optimal steady-state CIT converges to a standard inverse elasticity rule. \nRoom A406.

SUMMARY:Economics and Finance Seminar: Bertrand Garbinti (CREST)
DESCRIPTION:Abstract : Using exhaustive administrative wealth and income tax data\, we study a French wealth tax reform that scaled back information disclosure requirements below a certain wealth threshold. We develop a dynamic bunching approach that permits estimating the average response to the reform\, the share of compliers (bunchers) and the LATE. Reported wealth declines sharply in response to the reform and annual wealth growth rates are on average 20% lower among affected taxpayers. This decline appears due to increased evasion facilitated by the lower disclosure requirements. By contrast\, the elasticities to tax rates estimated are very small and insignificant. Responses to disclosure requirements are ten times larger than behavioral responses to kinks in the tax rates. To offset the revenue losses induced by the simplified reporting regime\, the government would need to increase the effective wealth tax rate paid by the bunchers by 22.5%. Together\, these results illustrate the critical role of information disclosure policies in shaping taxpayers’ behavior and tax revenues. \nRoom A406

SUMMARY:Economics and Finance Seminar: Levent Celik (Leicester School of Business)
DESCRIPTION:Stimulating Efforts by Coarsening Information and Prize Design (joint with Fabio Michelucci) \n  \nWe study a principal who jointly designs an information disclosure rule and a prize structure to maximize total effort in a two-agent contest. Agents are uncertain about their own ability and their opponent’s ability. The principal commits to a public disclosure rule — a mapping from ability profiles to messages — and chooses a general output-contingent prize schedule. We show that the optimal prize takes a simple form: a joint success prize k (awarded when both agents succeed) and a sole success prize m (awarded when only one succeeds)\, with no reward for joint failure. Moreover\, pure prizes always dominate mixed prizes: the optimal prize is always either k-only or m-only. This result reflects a fundamental economic distinction: k rewards joint success\, so incentives are stronger when the opponent is more likely to succeed — making effort choices strategic complements — while m rewards sole success\, so incentives are weaker when the opponent is more likely to succeed — making effort choices strategic substitutes. Under k-only\, the optimal disclosure progressively pools ability profiles into a single anonymous message. Under m-only\, the optimal disclosure reveals asymmetric profiles to induce the high-ability agent to exert. The optimal regime switches between k and m depending on the budget\, the success probabilities\, and the ability distribution. \nRoom A406

SUMMARY:Internal Seminar: Gustave Kenedi
DESCRIPTION:Title : Teacher Value Added and Higher Education Choices \nAbstract : We study the role of teachers in shaping students’ higher education choices in France. Focusing on “principal” teachers\, we estimate their value added across a range of outcomes capturing students’ post-secondary decisions\, drawing on administrative data on higher education choices from 2012 to 2022. The data allow us to observe a rich set of characteristics for each student\, which we use to address sorting and recover credible value-added estimates. Preliminary results suggest that principal teachers play an important role in shaping the higher education choices students make. \nRoom A406

SUMMARY:SITES-AICC conference 2026: Development and Climate Mitigation/Adaptation
DESCRIPTION:The Conference in Development and Climate Economics is jointly organised by SITES\, AICC and the Fondazione Tor Vergata of the University of Rome Tor Vergata. It will be held at Villa Mondragone\, Frascati\, Rome\, Italy\, from May 27th to 29th\, 2026 \n\n\n\n\n\n\n\n\n\n\n\nThe accelerating climate crisis poses complex and uneven challenges for societies across the globe. Understanding how climate change interacts with economic development\, institutional capacity\, technological progress\, and social well-being is now one of the most urgent and intellectually demanding tasks for researchers and policymakers alike. This conference brings together leading scholars\, practitioners\, and international institutions to advance frontier knowledge on the intertwined agendas of development and climate change mitigation and adaptation. \nWe invite contributions that deepen our theoretical and empirical understanding across a broad range of interconnected themes  such as climate economics\, governance\, and global policy; development\, poverty reduction\, and inequality; energy transition\, technological innovation\, and the green economy;  human capital\, institutions\, and societal resilience; urban–rural dynamics\, infrastructure\, and sustainable land and water systems; historical perspectives on development and climate. \nBy fostering dialogue across economics\, social sciences\, environmental studies\, history\, engineering\, and public policy\, the conference aims to generate actionable insights that can guide effective climate mitigation and adaptation strategies globally. We particularly welcome interdisciplinary approaches\, innovative methodologies\, and policy-relevant research capable of informing international cooperation and advancing a just and sustainable development agenda. \nMore information on the website of the conference.

SUMMARY:Internal Seminar: Anderson Vil (PSE)
DESCRIPTION:The Household Demand for Leisure\, the Price of Time and the Full Cost of Children: A Structural Model and Evidence from the PSID \nAbstract:\nWe propose a novel approach to estimating the full cost of children – the sum of monetary and time costs – by endogenizing the price of parental time rather than assuming it is equal to the parents’ wage rate. In this approach\, the price of time depends on how parents perceive their time with children\, whether as a leisure-like activity or more as a labor-like activity. We then develop a simplified collective model of leisure demand for working couples\, incorporating individual preferences and childcare technology\, and estimate it using 2019 PSID data. This allows us to recover the price of parental time and the full cost of children. We find that mothers perceive 44% of their childcare time as labor\, compared to 35% for fathers. Our results also highlight that a substantial portion of the full cost of children is non-monetary. \n  \nRoom A406.

SUMMARY:Economics and Finance Seminar: Radek Stefanski (University of St Andrews)
DESCRIPTION:Fiscal Fragmentation and the Evolution of Global Misallocation \nResource misallocation is central to development\, yet distortions are typically unobserved. We measure and characterise the evolution of a major source of global misallocation using more than a century of field-level data on production\, inputs\, and tax payments in a single sector — the global oil and gas industry. Distortions are substantial: the world’s current output could be produced with far fewer real resources if inputs were allocated to equalise pre-tax marginal products across fields. Because our data span more than a century\, we directly observe the emergence of this misallocation. We find that dispersion in wedges across countries has risen sharply since 1970\, driven by the divergence of sovereign fiscal regimes\, while dispersion within firms has remained flat. We call this pattern fiscal fragmentation. Embedding the measured wedges in a model of entry and production\, we quantify its aggregate cost: fiscal fragmentation accounts for around two-thirds of the sector’s total allocative inefficiency\, and operates almost entirely on the intensive margin. \n\nRoom A406

SUMMARY:Internal Seminar: Béatrice Boulu-Reshef
DESCRIPTION:Algorithmic Transparency and Portfolio Choices: Field Evidence (with Alexis Direr and Mehdi Louafi) \nThis paper studies whether profile-based explanations influence investors’ acceptance of algorithmic risk recommendations in a randomized controlled trial embedded directly in the platform’s interface of a leading French robo-advisor. Users were assigned either to see graphical explanations of the drivers underlying their recommended risk score and associated portfolio or to receive the standard interface with no explanation. Our results\, obtained in a real-world setting with actual clients of a FinTech\, do not support the adherence gains from increased transparency that are widely anticipated in the literature. We find a heterogeneous treatment effect as profile-based explanations lead to a greater downward deviation among desktop users who have already deviated to safer-than-recommended portfolios\, but this pattern disappears once users’ experience of the platform is taken into account. We observe non-causal evidence in both conditions that behavior is shaped primarily by the digital context and experience: phone and first-time users are more likely to accept the portfolio recommendation than desktop and returning users. While such transparency-enhancing profile-based explanations are informative\, they are not a universal lever for adherence\, suggesting that explanation design should be tested and tailored across device types and users’ experience. \nRoom A406.

SUMMARY:Internal Seminar: Dong Ook Choi (Sangmyung University)
DESCRIPTION:Title : News Selection by News Aggregators and Incentives for Newspapers to Invest in Journalism: The Case of South Korea \nAbstract:\nWe study news selection by two prominent Korean news aggregators. For this purpose\, we collect all online news articles of 52 national newspapers from South Korea for the year 2015\, along with all the articles posted on the homepages of the two aggregators\, whose joint share of news traffic was around 80%. We apply text analysis to the collected news articles to group them by topic through a clustering process and measure their degree of copying from preceding news content within each topic cluster. Using this data\, we calculate the originality rate of each article\, along with other quality factors such as article length\, the presence of bylines\, and whether the title includes breaking news or exclusive label. We first study selection of news topics (i.e.\, news clusters) by the two aggregators and find that the probability of selection increases with the size of the cluster\, the number of newspapers which contribute articles\, the average originality of articles and the average length of articles. We also find that on average\, the 10.8th article within a specific cluster is the first to be selected by the aggregators. We then study selection of news articles by the aggregators and find that articles with higher originality\, longer length\, and exclusiveness are more likely to be selected. Surprisingly\, we find that the rank of an article in terms of the time order it is posted is unrelated to its selection probability. These results suggest that there is little premium for being the first to break a news story\, which seriously undermines Korean newspapers’ incentive to invest in journalism. We provide an explanation based on incomplete information about importance of topics and short-termism. \nRoom A406.

SUMMARY:Economics and Finance Seminar: Quang Vuong (New York University)
DESCRIPTION:Differentiated Products with Endogenous Choice Sets \nThis paper extends the equilibrium model of Berry\, Levinsohn and Pakes (BLP\, 1995) by endogeneizing the consumers’ choice sets. We introduce an entry stage preceding the Bertrand pricing game where firms choose which products to offer. We show that the demand and cost parameters are identified under selectively offered products. We then propose a semiparametric modification of the BLP estimator that accounts for the endogeneity of the choice set. A Monte Carlo study shows the inconsistency of the usual estimators and the good performance of our estimator in finite samples. \nRoom A406

SUMMARY:Internal Seminar : Mariona Segú
DESCRIPTION:This paper studies the impact of increasing minimum contract length on tenant stability and rental market outcomes. We exploit a 2019 reform in Spain that extended rental contracts from three to five years for individual landlords and to seven years for corporate landlords\, using the universe of rental agreements in Catalonia (2016–2024) and a regression discontinuity design around the reform date. We find a strong increase in contract length for both landlord types\, with no significant effects on rents\, contract volume\, or short-term contracts for individual landlords\, who represent most of the market. Some short-run adjustments appear for corporate landlords\, but they are confined to a one-week anticipation period. In the medium run\, longer contracts increase tenant stability\, driven by fewer renewals with the same tenant among individual landlords and lower market exit among corporate landlords. Overall\, extending contract duration enhances tenure security without generating substantial adverse effects on prices or supply. \nRoom A406.

SUMMARY:Economics and Finance Seminar: Etienne Le Rossignol (Namur University)
DESCRIPTION:In-Group—Out-Group Trust: Origins and Consequences \n\n\nWhy do societies differ in the breadth of trust they extend beyond the in-group? This paper argues that historical mobility\, specifically\, the ecological and institutional demands of transhumant pastoralism\, shaped long-run variation in the scope of trust. Combining global data from 104 countries\, individual-level surveys\, and within-country evidence from Kyrgyzstan and Africa\, we show that ancestral reliance on transhumant pastoralism predicts higher trust in in-group members relative to out-group members. We then uncover the mechanism using a newly assembled Atlas of Transhumance Routes: the effect is significantly stronger along flatter\, more “horizontal” routes that historically generated recurrent encounters with other pastoralists under weak external enforcement. These routes intersect more ethnic boundaries\, and the intensity of such encounters amplifies the transhumance-trust relationship\, especially where interactions involved competing pastoral groups. A natural experiment\, the 2011 partition of Sudan\, which abruptly obstructed long-standing migration corridors\, shows that conflict rises sharply along historical routes once mobility becomes constrained. Finally\, we show that a narrower scope of trust constrains organizational hierarchies: firms in historically pastoral regions rely less on objective promotion criteria and remain smaller. Together\, the results highlight the enduring cultural and economic consequences of historical mobility.

SUMMARY:Internal Seminar: Zijun Cheng
DESCRIPTION:China Shock and the Internal Organization of Firms: Evidence from French Business Groups \nThis paper studies how French business groups reorganize in response to China’s rise in global trade. Combining firm- and group-level data on ownership links\, foreign affiliates\, trade exposure\, and occupations\, we examine both domestic adjustments in management structure and changes in the international organization of firms. We construct exposure measures based on pre-shock industry composition and show that more exposed groups reallocate managerial resources within France and adjust their foreign affiliate networks. These patterns suggest that trade shocks reshape not only production and employment\, but also the internal organization of business groups. The findings highlight the role of business-group restructuring in mediating the domestic effects of globalization. \nRoom A406.

SUMMARY:Economics and Finance Seminar: Hugo Lhuillier (Columbia University)
DESCRIPTION:The Local Root of Wage Inequality \nWages are on average higher in larger cities\, yet the real earnings of low-wage workers are lower. Using French administrative data\, I document two novel facts. Large cities concentrate high-paying jobs\, while low-paying jobs are everywhere. The reallocation of workers across jobs spurs faster wage growth in larger cities. I propose a framework that rationalizes these facts. Productive employers agglomerate in large cities to maximize their size. Fiercer competition steepens the local ladder\, and workers accept lower real earnings anticipating future wage growth. After estimating the model\, I find that housing-adjusted unemployment benefits amplify spatial disparities but raise aggregate welfare. \nRoom A406
