The economic agent was previously assumed to be distinct from its environment and that nothing was forcing him to act on it. With the ecological crisis, every agent appears to be inserted into an environment, which he modifies in an irreversible way without even having decided to do so. This changes in depth the way in which economics can represent the agent and the optimal action: it is rationality itself that is modified in what we call "ecological rationality".
We analyse the current and possible ways forward in this consideration of climate and biodiversity by finance, highlighting the extent to which they may either contribute to and/or suffer from those environmental changes.
Nos résultats montrent que le niveau de divulgation climatique influence positivement la performance financière mesurée par le Market to Book et le Q de Tobin. Toutefois, on constate des différences importantes selon les pays.
We examine the efficiency of a subsidy to cattle farmers for setting aside land for natural ecosystem regeneration. We develop a partial equilibrium model of the cattle sector that integrates land use, greenhouse gas emissions, and animal feeding. We identify conditions under which the subsidy is the best alternative to these other second-best policies.
Le possible rejet du pacte vert aux élections européennes doit faire réfléchir à de nouvelles modalités de débattre et de décider du processus de la transition écologique, estime Jézabel Couppey-Soubeyran dans sa chronique pour Le Monde.
We study the macroeconomic impact of climate action policy that would allow France to reach its net zero objective by 2050. Contrary to the findings of a report commissioned by the French Prime Minister, our simulations show that these investments are likely to generate economic growth and reduce public debt.
Ce séminaire sera consacré aux enseignements qui peuvent être tirés de certains modèles macroéconomiques utilisés pour étudier l’impact des politiques climatiques et les problèmes de financement qui en résultent.
La Chaire Énergie et Prospérité et l'Institut Veblen organisent conjointement un cycle de séminaires consacrés au financement de la transition écologique.
La première séance, organisée le mercredi 29 mai, à Maison des sciences économiques (Paris 13), sera consacrée aux besoins de financements.
We document the relationship between rural–urban migration and energy poverty in South Africa. Our findings show that migrants to urban areas experience significant reductions in energy poverty, particularly in the use of traditional cooking fuels. Our study also explores energy poverty outcomes for both sending and receiving households, gender differences among migrants, and other amenities.
La chaire Énergie et Prospérité et le Cired organisent, à l'occasion de la sortie du livre Un nouveau contrat écologique d'Emmanuel Combet et d'Antonin Pottier, un débat avec les deux auteurs ainsi que Marc Fleurbaey et Thierry Pech.
