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.
The distribution of the footprint within a country is regularly computed using consumption data, and with the assumption that the footprint from a product category is proportional to the spending on that product. Here, we explore the limitations of this proportionality assumption.
Cette thèse met en évidence les relations complexes entre électrification, déforestation et développement économique dans les pays en développement.
In September 2020, the city of Bogotá introduced a major market-based reform to its odd-even driving restriction. The big winners of the reform are middle-income individuals who now use their cars more often, whereas the big losers are high-income individuals who now spend more time in traffic.
Adopting disruptive technologies for decarbonizing hard-to-abate industrial sectors requires experimentation through demonstration (pilot) projects. However, from an economic perspective, the potential long-term benefits and the difficulties in designing relevant public policies are not addressed in the standard valuations of those projects.
