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.
