How the increased trade openness and correspondingly higher marginal propensity to import explains the lower efficiency of economic policy in the context of economic openness. Using an empirical stock-flow consistent model for the French economy (SFC FR), we analyze the macroeconomic impacts of these policies through a series of macroeconomic shocks.
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...
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.
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.

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.

Electric batteries and fuel cells (hydrogen) are competing technologies for the energy transition in heavy transportation. This paper shows that the existence of a market niche for fuel-cell electric buses (FCEBs) can be obtained depending on the values of a limited set of key parameters.
Several European governments implemented a generalized gasoline subsidy in the face of inflation following the Ukrainian crisis. In contrast, reducing fossil fuel consumption is crucial to mitigate the current energy and climate crises. Fuel consumption for transport increases with income, making rich households the main beneficiaries of generalized subsidies. In this context, a thorough...
Cette note tente de définir les contours de la planification écologique nécessaire en s’appuyant notamment sur les expériences passées et récentes. Seront successivement analysés (1) les obstacles à la transition écologique qu’il convient de surmonter, (2) les leçons des expériences de planification passées et récentes et (3) les pistes permettant de réinventer la planification française pour promouvoir la...
Dans une note à paraître prochainement dans la Revue de l'Energie, Guy Meunier et Jean-Pierre Ponssard montrent : (i) Que la définition d’un indicateur dynamique de coût d’abattement, évaluant le déploiement d’une technologie décarbonée en substitution d’une technologie carbonée, est une approche plus complète que celle des coûts d’abattement traditionnels , et qu’elle débouche sur une préconisation d’accélération des programmes...
