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.
Using an empirical stock-flow consistent (SFC) model for the French economy, we simulate an imported inflationary shock to emulate the current inflation situation and analyze the resulting macroeconomic impacts on the French economy. Two possible responses are considered: increased wage per capita so as to preserve workers’ purchasing power, increased margins by firms in order to restore their...

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...
Il n’est pas certain que l’expérience terrestre soit heureuse, comme il n’est pas certain que les hommes aient le désir de la faire durer. Il se pourrait ainsi que la répugnance à la condition terrestre soit la première raison de l’inaction écologique.
The cattle sector, both emissions- and land-intensive, represents a great opportunity for mitigation through reforestation. In this paper, we study the efficiency of land-use regulation. Our analytical results indicate that the subsidy is the best alternative policy to emissions tax, provided that the elasticities of land use and emissions to cattle feeding are close. Interestingly,...
Our analysis of the Climate Risks and Opportunities Index (CRORI) and the CDP climate score reveal a parallel improvement of these indices with different sectoral disparities over the 2015–2019 period. While our results are encouraging, they need to be put into perspective because these firms are still far from being carbon neutral.
