SUMMARY:Arthur SILVE (U. of Laval)  - "Migration and Cultural Change (avec Hillel Rapoport et Sulin Sardoschau)"
DESCRIPTION:Séminaire Microéconomie : Tous les mercredis\n Heure : 12h15 – 13h30 \nDate : 21 septembre 2022 \nSalle : 3001 \nArtur Silve (U. de Laval) – “Migration and Cultural Change (avec Hillel Rapoport et Sulin Sardoschau)” \n  \nCV  : We propose a novel perspective on migration and cultural change by asking both theoretically and empirically – and from a global viewpoint – whether migration makes home and host countries culturally more similar. Our theoretical model derives distinctive testable predictions as to the sign and direction of cultural convergence for various compositional and cultural diffusion mechanisms. We use the World Value Survey for 1981-2014 to build time-varying measures of cultural similarity for a large number of country pairs and exploit within country-pair variation over time. Our results support migration-based cultural convergence\, with cultural remittances as its main driver. \n  \nOrganisateurs :\n Julien COMBE (Pôle d’Economie du CREST) \n​​Roxana FERNANDEZ (Pôle d’Economie du CREST) \n​​Matias NUNEZ (Pôle d’Economie du CREST) \nCommanditaires :\n CREST \n

SUMMARY:Gauthier VERMANDEL (Dauphine & X ) "Environmental Subsidies to mitigate Transition Risk". "
DESCRIPTION:The Macroeconomics Seminar:\nTime: 12:15 pm – 13:30 pm\nDate: 26th of September 2022 \nRoom 3001 \nGauthier VERMANDEL (Dauphine & X ) “Environmental Subsidies to mitigate Transition Risk”. \nAbstract : We explore the role of public subsidies in mitigating the transition risk associated with a climate-neutral objective by 2060. We develop and estimate an environmental dynamic stochastic generalequilibrium model for the world economy featuring an endogen ous market structure for green products. We show that public subsidies\, financed by a carbon tax\, are an efficient instrument to promote firm entry into the abatement goods sector by fostering competition and lowering the selling price of such products. We estimate that the subsidy\, optimally distributed between startups at 60% and existing companies at 40%\, will save nearly $2.9 trillion in GDP each year by 2060. \nJoint work : Eric Jondeau (Univ of Lausanne)\, Grégory Levieuge (Banque de France)\, Jean-Guillaume Sahuc (Banque de France) \nOrganizers:\nGregory CORCOS (Ecole Polytechnique et CREST) \nSponsors:\nCREST \n

SUMMARY:Eddie Aamari  (Sorbonne University) "Statistical Query Complexity of Manifold Estimation"
DESCRIPTION:Statistical Seminar: Every Monday.\nTime: 3:45 pm – 5:00 pm\nDate: 26 of September 2022\nPlace: Amphi 200 \nEddie Aamari (Sorbonne University) “Statistical Query Complexity of Manifold Estimation” \nAbstract: In this talk\, we study the multi-task learning problem that aims to simultaneously analyze multiple datasets collected from different sources and learn one model for each of them. We propose a family of adaptive methods that automatically utilize possible similarities among those tasks while carefully handling their differences. We derive sharp statistical guarantees for the methods and prove their robustness against outlier tasks. Numerical experiments on synthetic and real datasets demonstrate the efficacy of our new methods. \n  \nOrganizers:\nCristina BUTUCEA (CREST)\, Alexandre TSYBAKOV (CREST)\, Karim LOUNICI (CMAP) \, Jaouad MOURTADA (CREST)\nSponsors:\nCREST-CMAP \n
