SUMMARY:Séminaire: Chloé Lecoq (U. Panthéon-Assas)
DESCRIPTION:Séminaire d’économie de Bordeaux\n  \nChloé Lecoq\n (Université Paris Panthéon Assas\, CRED) \n  \n« Legally Binding Energy Solidarity: the Green Transition-Equity Trade-off in the EU »\ncoécrit avec E. Paltseva (Stockholm School of Economics\, SITE) \n \n« As electricity systems become more interconnected and reliant on variable renewable energy\, cross-border solidarity rules act as risk-sharing mechanisms shaping both crisis outcomes and ex ante investment incentives. We develop a model of interconnected countries facing stochastic supply shortages and compare two solidarity designs used in EU energy law: a capacity-based rule (electricity)\, where support depends on the assisting country’s capacity\, and a loss-based rule (gas)\, where support is tied to the affected country’s shortage. These rules generate a fundamental scale–parity trade-off. The loss-based rule increases aggregate green investment but amplifies cross-country disparities\, while the capacity-based rule reduces disparities at the cost of lower investment. We show that the optimal rule depends on asymmetries in endowments and supply risks: with moderate asymmetries\, loss-based solidarity dominates\, whereas with large or concentrated asymmetries\, capacity-based rules can dominate by limiting divergence and moral hazard. \nSimulations calibrated to EU data illustrate how solidarity design can shape both the speed and distribution of the green transition. »\n \n \n*** changement de salle : salle H1-102\n \n \n \n– Séminaire organisé par le programme 4 / BSE –\n \n  \n>> pour assister au séminaire via Zoom\, contacter julie.vissaguet@u-bordeaux.fr \n\n \nAgenda > Tous les événements\n\n \n  \n  \n
