SUMMARY:Economics and Finance Seminar: Carlos Serrano (HEC Paris)
DESCRIPTION:Acquiring Patents in Secret: Disclosure Timing in Markets for Technology \nMarkets for technology provide a vibrant channel through which firms purchase ownership rights to patented inventions. Although such transactions enable firms to secure access to intangible assets originating beyond their borders\, they also provide cues to competitors regarding the purchasing firm’s technological investments. This study explores the timing of strategic disclosure of patent acquisitions and the conditions under which firms trade the benefits of competitor deterrence through early recordation for those of secrecy through delayed disclosure. Using evidence on the lag between the execution and recording dates for US patents purchased by publicly traded corporations\, we predict and find earlier disclosure of patent acquisitions when the buyer works on related technologies and is better positioned to enforce the patents (i.e.\, is large and relatively litigious). As predicted by the model\, we also find that the buyer delays disclosure when the seller is a large firm\, suggesting that buyers take advantage of the seller’s ability to deter competitors while keeping the transaction secret. Additional analyses reveal that (a) regulatory changes reducing the value of keeping acquisitions of patent applications secret lead to shorter recording lags\, and (b) increases in the enforceability of business method and software patents further accelerate the voluntary recording of patent ownership changes. The study provides new evidence on the tradeoffs that innovating firms face when determining the timing of disclosure for patents they have purchased in technology markets. \n  \nRoom A406

SUMMARY:Internal Seminar: Omar Al-Humsi
DESCRIPTION:Redistributive Labor Income Taxation with Directed Technical Change in a Unionized Economy \nWhat are the implications of endogenous directed technical change for the design of redistributive income taxes in a unionized economy ? I study this within a general equilibrium framework featuring two types of labor that supply labor along the extensive margin. Wages are determined through union–firm bargaining\, while the direction of technology is chosen endogenously by profit‐maximizing firms\, following the directed technical change framework of Acemoglu (2007).\nRoom A406.

SUMMARY:Economics and Finance Seminar: Graziella Bertocchi (Università di Modena e Reggio Emilia)
DESCRIPTION:Family Planning and Ethnic Heritage: Evidence from Sub-Saharan Africa (with Arcangelo Dimico and Chiara Falco) \n\n\n\nUsing ethnographic\, ecological\, and folklore data for sub-Saharan Africa\, we investigate the role played by postpartum sexual abstinence\, an extensively documented practice that in preindustrial societies finds its biological justification as a means to safeguard child survival. We show that the duration of contemporary postpartum abstinence increases with that of ancestral postpartum sex taboos within a woman’s ethnic group; raises fertility; lengthens birth intervals though not sufficiently to meet recommended guidelines; is detrimental for children’s health; is associated with lower age at first birth and female disempowerment; and is adopted \nas a purification ritual\, out of respect of ancestral traditions.\n\n\n\n\n\n\n\n\n\n\n\n\nRoom A406

SUMMARY:Internal Seminar: Eddy Zanoutène
DESCRIPTION:Optimal Taxation of Undistributed Profits (with Etienne Lehmann) \n\n\n\nWe study the optimal combination of corporate and dividend taxes when retained earnings can be used to avoid taxation. We show that eliminating dividend taxes while raising the corporate income tax can increase total revenue without affecting investment. Our simulations indicate revenue gains of 0.1–0.5\% of GDP. In an infinite-horizon model\, the optimal policy sets dividend taxes to zero in every period. This result holds regardless of the welfare weights assigned to capitalists and workers.\n\nRoom A406

SUMMARY:Economics and Finance Seminar: Sylvain Carré (Paris 1)
DESCRIPTION:Title: Efficiency in DeFi Lending: Interest Rate Mechanisms and Liquid Staking\n\nAbstract: Liquid staking\, a notable recent innovation in decentralized finance (DeFi) allows to delegate and redeploy capital which was traditionally locked and has thus been promoted for its “capital efficiency” virtues. In the context of DeFi lending\, we build a tractable general equilibrium model to analyze two strategic interactions between investors\, which\, we show\, affect the performance of liquid vs traditional staking. We find that without a proper adjustment of the DeFi lending interest rate mechanism\, liquid staking can worsen efficiency even when there are no delegation costs. When the interest rate is optimally set\, a combination of mild delegation costs and limited investor competition can lead to the same conclusion. \n\n\n\n\n\n\n\n\n\n\n\nRoom A406

SUMMARY:Internal Seminar: Margaux Suteau (LSE)
DESCRIPTION:Empowering Parents in the Digital Age \nWhile economic research documents substantial negative effects of social media on youth outcomes\, the role of parents in mediating these effects remains largely unexplored. We propose digital parenting as a new form of human capital investment and test whether interventions can shift parents’ beliefs and practices\, as well as children’s outcomes. Drawing on a UK household longitudinal survey\, Understanding Society\, we first document that intensive social media use is associated with greater behavioural problems among children\, and that parenting styles predict children’s digital exposure. We then conduct our own longitudinal survey on 1\,800 UK parents\, and implement two randomized interventions: (i) an information treatment providing evidence on the risks of social media\, and (ii) a four-week video training on digital parenting strategies. The information treatment increased support for school no-phone policies by 47% relative to the control group mean and actual participation in follow-up training by 37%\, though it also raised parental anxiety by 20%. The video training generates suggestive evidence of improvements in parenting practices\, particularly communication strategies. Effects on children’s outcomes are modest but suggest reductions in screen time. Treatment effects vary substantially by parenting style: permissive parents respond most strongly to both interventions. These findings suggest that while providing information can effectively shift beliefs and\, to some extent\, practices\, it involves welfare trade-offs. \nRoom A406 \n

SUMMARY:Economics and Finance Seminar: Alexandre de Cornière (Toulouse School of Economics)
DESCRIPTION:Seller-Side Tying of Platform Services\, joint with Kinshuk Jerath and Greg Taylor\n\nThis paper analyzes the practice of seller-side tying in digital platforms\, where access to a core intermediation service is conditioned on the seller using ancillary services such as fulfillment or payment processing. We develop a model in which a monopoly platform intermediates transactions between consumers and competing sellers\, and can choose whether to force the sellers to tie a costly ancillary service to the core offering. Consumers value the ancillary service heterogeneously\, and seller adoption decisions generate vertical differentiation that affects market prices and consumer platform participation. We show that tying resolves under-adoption of the ancillary service\, increases competition between sellers\, and raises consumer surplus. In contrast\, a ban on tying or a structural separation of the platform reduces service adoption and harms consumers. These results differ from consumer-side tying where\, in our setting\, bundling the core and ancillary services is neither profitable for the platform nor beneficial to consumers. The efficiency rationale for seller-side tying is robust under multiple variations of our main model.\n\n\nRoom A406

SUMMARY:Internal Seminar: Linus Thierry Nana Noumi
DESCRIPTION:Measuring Differences of Opinion: Axiomatic Foundation\, Utility\, and Truthtelling\nUnderstanding how individuals and groups differ in their opinions and preferences is central to analyzing disagreement\, measuring polarization\, designing institutions\, and predicting collective outcomes. Yet comparing preferences requires more than observing how each person ranks alternatives–it requires a method for comparing preference orderings themselves. This paper develops a formal framework to infer how individuals might rank different preference orderings based solely on their observed preferences. We introduce a set of natural and behaviorally plausible axioms–Independence (I)\, Disagreement Aversion (DA)\, and Symmetry (S)–and show that they uniquely characterize a class of hyperpreference relations and their associated utility representations. We apply this framework to the study of aggregation mechanisms\, deriving necessary and sufficient conditions on utility structures that induce truthful preference reporting in equilibrium and guarantee efficiency. Our results yield new insights into strategyproof mechanism design under deep preference heterogeneity and clarify when differences of opinion can be meaningfully and reliably measured. \nRoom A406

SUMMARY:Economics and Finance Seminar: Gabrielle Fack (Dauphine University - PSL)
DESCRIPTION:The Effects of Affirmative Action on Targeted and Non-Targeted Students: Evidence from Low-Income Priorities in Paris High Schools » Gabrielle Fack (Université Paris Dauphine-PSL)\, Julien Grenet (Paris School of Economics)\, YingHua He (Rice University) \nSince 2008\, school choice in Paris has an income-based affirmative action component giving low-income students preferential treatment in high school admissions. This policy is implemented through a centralized school choice process that assigns students to public schools. Students’ priorities are determined by a point system that takes into account students’ academic performance and their district of residence. Low-income students\, who make up about 20 percent of high school freshmen\, receive in addition a large bonus that gives them full priority at all public high schools in their district. Using comprehensive administrative data\, we use the implementation of this bonus in 2008 as a natural experiment to examine the effects of income-based affirmative action on high school outcomes and college access for both targeted and non-targeted students. \nRoom A406.

SUMMARY:Internal Seminar: Javier Terrero (Paris-Saclay University)
DESCRIPTION:Who Gets Ahead? Comparative Evidence on Intragenerational Mobility from Administrative Microdata \n\n\nWe use administrative records from Austria\, Belgium\, Estonia and Spain to study income dynamics of working-age individuals over five years. Aggregate mobility indices often mask substantial variation in short-term income trajectories for individuals at different points of the distribution. By combining relative and absolute mobility metrics that can be aggregated at the percentile level\, we provide granular comparative evidence of intragenerational mobility both across countries and across socio-demographic groups. Our results show that cross-country differences in mobility patterns are particularly pronounced at the bottom and top of the distribution\, while outcomes in the middle are more alike. Large cross-country differences in relative income growth or rank advancement at the bottom often translate into only modest differences in absolute living standards\, underscoring the importance of considering different mobility metrics when comparing mobility across countries. Overall\, Estonia exhibits greater relative and absolute intragenerational mobility than the other three countries. Across demographic groups\, individuals with lower educational attainment and immigrants experience weaker mobility outcomes across the entire distribution in all countries. Women experience worse mobility outcomes at the bottom of the distribution\, although the gap narrows in the upper half in Belgium\, Estonia and Spain. Age and rural–urban differences vary by initial income position and are not consistent across countries.\n\nRoom A406

SUMMARY:Economics and Finance Seminar: Ylenia Brilli (Cà Foscari University of Venice)
DESCRIPTION:How raising the full retirement age affects women’s early retirement choices: insights from the interaction of two policies (with Elena Bassoli\, ETH Zurich) \nThis paper analyzes how a reform increasing statutory retirement age from 60 to 64 affected women’s incentives for early retirement. In Italy\, women can anticipate retirement at 57 (with 35 contribution years)\, but subject to an annuity penalization. Using Italian administrative data\, we compare women eligible for the early retirement scheme before and after the reform\, finding a small effect on women’s retirement age\, but a substantial negative effect on annuity. Effects are stronger for women with low labor market attachment or working full-time\, suggesting that reconciliation of paid and unpaid works is an important driver of early retirement choices. \nRoom A406

SUMMARY:Economics and Finance Seminar: Christian Hilber (LSE)
DESCRIPTION:Structural Density and Homeownership \nOne of the most salient stylized facts about homeownership is that multifamily units—typically located in more central parts of cities—are much less likely to be owner-occupied than single-family units. This fact is consistent with landlord production efficiency advantages associated with structural density\, arising from economies of scale and coordination frictions. To derive testable predictions and guide our empirical analysis\, we develop a simple modified monocentric city model that incorporates these efficiency advantages and spatial variation in structural density due to centrality and soil conditions. To identify the causal effect of structural density\, and to disentangle it from other determinants of homeownership\, we employ a novel instrumental variable (IV) strategy derived from the engineering literature\, exploiting differences in soil quality. Using data at the ward level in England and grid level in Germany\, our IV-estimates show that a ten–percentage-point increase in the share of multifamily housing reduces the local homeownership rate by about eight to nine percentage points. The magnitude of this effect aligns with observed spatial differences in homeownership within England and Germany (in-sample) and across Europe (out-of-sample). In England\, about half of the effect reflects sorting\, whereas in Germany sorting appears negligible. We provide direct evidence for our proposed mechanism and confirm our findings using an alternative empirical strategy based on a large European household panel.

SUMMARY:Internal Seminar: Markus Poschke (McGill)
DESCRIPTION:Skill Supply\, Firm Size\, and Economic Development \n\n\n\nThis paper harmonizes individual-level data on labor supply for 54 countries to document how firm size and the skill intensity of employment by firm size vary across countries. First\, it finds that the share of employment in large firms in high-income countries is more than three times larger than in low-income countries. Second\, it shows that across countries\, employees of large firms are more skilled than those of small firms. Third\, it documents that lower skill endowments in low-income countries affect employment in firms of different sizes asymmetrically: the skill intensity of employment is much lower in small firms in low-income countries than in high-income countries\, but only slightly lower in large firms. This evidence suggests that large firms rely particularly strongly on employing high-skill workers\, so that the low skill endowment of low-income countries limits the size of firms in these countries.

SUMMARY:Economics and Finance Seminar: Natacha Raffin (ENS Paris-Saclay)
DESCRIPTION:New fertility patterns: The role of human versus physical capital \n\n\n\n\n\nWe use an overlapping generations model with physical and human capital\, and two reproductive periods to explore how fertility decisions may differ in response to economic incentives in early and late adulthood. In particular\, we analyze the interplay between fertility choices—related to career opportunities—and wages\, and investigate the role played by work experience and investment in both types of capital. We show that young adults postpone parenthood above a certain wage threshold and that late fertility increases with human capital. The long run trend is either to converge to a low productivity equilibrium\, involving high early fertility\, investment in physical capital and relatively low income\, or to a high productivity equilibrium\, where households postpone parenthood to invest in their human capital and work experience\, with higher late fertility and higher levels of income. A convergence to the latest state would explain the postponement of parenthood and the mitigation or slight reversal of fertility decrease in some European countries in recent decades.

SUMMARY:Internal Seminar: Mohammad Lashkarbolookie
DESCRIPTION:Prosocial Disclosure and Contracts\n\nThis paper studies prosocial disclosure (e.g.\, ESG reporting) and prosocial contracts (e.g.\, sustainability-linked loans) in a multitasking principal–agent framework with limited liability and private agent types. The agent exerts costly effort on two tasks: one yielding an unverifiable outcome and another generating an outcome that can be verifiably disclosed at a cost. The agent’s private type captures their intrinsic utility over the outcomes\, which affects both parties’ gain from contracting on the verifiable information. The main result is the ambiguous effect of a mandatory disclosure regulation. While a disclosure mandate can enhance prosocial effort and welfare when the voluntary regime yields non-disclosure\, it can reduce welfare when full disclosure emerges voluntarily. In cases where voluntary disclosure is partial\, mandating disclosure can either improve or undermine contracting efficiency and welfare\, depending on the specification of agent types and the principal’s objective.

DESCRIPTION:An economic analysis of extra-territorial taxation\, joint with G. Zucman \n\n\n\nThis paper proposes an economic analysis of extraterritorial tax policy. We consider a country imposing top-up taxes to the foreign profits of multinational firms to ensure a minimum effective corporate tax rate. We analyze the incidence of this tax\, its domestic and global welfare effects\, and derive conditions for optimal unilateral policy in a flexible multinational monopoly model. We obtain four main results. First\, extraterritorial taxation generates additional tax revenues but leads to domestic price increases. When foreign profits are not taxed\, the tax revenue gains dominate consumer welfare losses even for small countries. Second\, when the foreign tax rate is positive\, welfare effects are ambiguous. The optimal extraterritorial rate rises with domestic market shares and falls with foreign tax rates. A large enough country (or coalition of countries) can top-up foreign taxes\, but a small country alone cannot overtax firms that are already heavily taxed abroad. Third\, taxing the undertaxed profits of foreign multinationals has generally better welfare effects than tariffs. Last\, revenue gains from extraterritorial profit taxation increase quadratically with country size. Extraterritorial tax collection turns the logic of tax competition on its head: large destination market countries (for which revenue gains typically swamp price increases) have incentives to tax the undertaxed profits of multinational firms\, which can lead to a race-to-the-top with corporate income tax rates.

SUMMARY:Economics and Finance Seminar: Catherine Roux (University of Basel)
DESCRIPTION:Spheres of Influence in Multigame Contact \n\nWe study the effect of multigame contact in asymmetric prisoner’s dilemma games. Players simultaneously play two games either with the same partner (multigame contact) or with different partners (single-game contact). Asymmetry arises because one game is more valuable to one player\, while the other game matters more to the other player. Efficiency requires coordination on “spheres of influence”: each player concedes in the game valued by the other in exchange for gains in their own priority game. Our experiments show that such equilibria enable players to realize the efficiency gains that theory predicts for multigame contact\, contrasting with earlier experimental studies that found no such gains. The results suggest that as firms expand across markets\, collusion may emerge through spheres of influence rather than market-by-market coordination.

DESCRIPTION:Gendering On The Confucian Clan: A Social Cost Perspective\n\n\n\n\nThis paper unbundles the role of the Confucian clan through a systems approach\, focusing on its long-lasting effects on women by shaping a traditional gender institution in China. Specifically\, we ask whether the Confucian clan\, as a risk-sharing institution\, perpetuates itself by reinforcing a patrilineal system through establishing gender-based norms and choice sets and confining women to the private sphere (inside the household)\, thereby compelling women to disproportionately bear the social costs. Using nationally representative survey data and an instrumental variable approach\, we find that the Confucian clan explains a significant portion of traditional gender norms\, and shapes a distinct choice set for men and women\, including earlier marriage\, son preference\, gender disparities in human capital formation\, and a traditional gender-based division of labor in both households and workplaces. In addition\, the effects on traditional gender norms persist among immigrants\, alleviating concerns about confounding influences from region-specific characteristics. Furthermore\, we find that when the Dibao program\, a minimum livelihood guarantee program in China\, replaces the Confucian clan’s role in risk sharing\, gender norms become more liberal and son preference diminishes.

DESCRIPTION:Tax Policy Design in a Globalized Economy: A Comparative Analysis of Destination and Origin Principles\n\n\nAbstract: This paper examines the optimal structure of commodity taxation in an open economy characterized by firm mobility and labor market segmentation. We develop a two-country general equilibrium model with monopolistic competition\, endogenous firm relocation\, and a dual labor market in which skilled workers earn flexible wages while unskilled workers face wage rigidity. Within this framework\, we compare the welfare implications of two competing tax principles: the destination principle (taxation at the point of consumption) and the origin principle (taxation at the point of production). Our central finding is the existence of a threshold condition: when the share of production income accruing to skilled labor exceeds 50%\, the origin principle Pareto dominates in a non-cooperative setting; otherwise\, the destination principle yields superior outcomes. This result offers a tractable\, empirically grounded decision rule based on observable labor market parameters and sheds new light on the design of international tax coordination mechanisms.

DESCRIPTION:Owning More of the Chain: Capital Subsidies and Firm-Level Upstream Shifts in China\n\nThis paper examines the causal effect of China’s capital-goods import subsidy on firms’ production organization from a global value chain perspective. Implemented through the Catalogue for the Guidance of Importing Technologies and Products\, the policy subsidized high-tech equipment to promote industrial upgrading and deeper GVC integration. A partial-equilibrium model shows that lower equipment rental rates reduce stage-specific marginal costs and expand firms’ span of integration\, with stronger effects in capital-intensive upstream stages. Guided by this framework\, the empirical analysis combines matched firm-product-year customs and production data in a difference-in-differences design around the 2008 rollout. Treated firms expanded their span of production stages\, with effects concentrated on upstream imports; on average\, the span increased by about 0.14 stages. Event studies show flat pre-trends\, placebo tests yield null effects\, and robustness checks confirm results. These findings demonstrate how targeted equipment subsidies can accelerate vertical upgrading and reposition firms within global value chains.

SUMMARY:Economics and Finance Seminar: Lisa Botbol (Monash)
DESCRIPTION:Applicant choice in the design of social housing allocations : Evidence from France\nAlthough social housing is prevalent in many developed countries\, there is no consensus over how to design allocation rules. Measuring the impact of a change in rules requires predicting how applicants will respond. In a context where rents are fixed\, application data scarce\, and allocation rules lack transparency\, disentangling an applicant’s preferences from their probability to receive an offer is challenging. This paper develops a dynamic framework which makes use of a novel\, comprehensive dataset of French social housing applications to separately identify preferences of applicants to social housing from their expectations over future offers and the allocation rules. This allows to compare the welfare impact of changes in the allocation rules. Results indicate that the current system favors households with French nationality\, and disadvantages precarious households like single mothers compared to the rest of the population. Counterfactual analysis suggests better targeting low-income households would significantly improve welfare. Mechanisms based on applicant waiting time like first-come-first-serve are shown to be welfare-reducing.

SUMMARY:Internal Seminar: Jean Toupouvogui
DESCRIPTION:Policy and inequality response to uncertainty shocks: A multi-country analysis\n \nThis paper investigates the effects of uncertainty shocks on public debt and inequality across 25 developed and emerging economies over an average period of 30 years\, using a structural vector autoregression (SVAR) framework. While uncertainty shocks are generally recessionary\, their macroeconomic and distributional effects vary significantly across income group. In emerging markets\, shocks propagate mainly through demand-driven channels\, triggering deeper and more persistent declines in output\, consumption\, and investment compared to advanced economies. Public debt increases in both groups\, but more sharply and durably in high-income countries\, reflecting stronger fiscal and monetary responses. Distributional effects diverge: income inequality tends to fall in advanced economies but rises in emerging markets\, particularly among low-income groups. In advanced economies\, wealth inequality increases as asset recoveries benefit the top. These asymmetries are closely linked to differences in public generosity—proxied by per capita transfers and subsidies—highlighting the role of fiscal capacity in shaping the macroeconomic and social consequences of uncertainty.
