Les pratiques de mobilité des Français. Graphiques de novembre 2024 issus d’une analyse avec Fabien Perez (SDES) à partir des données de l’enquête mobilité des personnes (EMP) de 2019.
Despite extensive research on sustainable business models and the development of various tools to facilitate their implementation, barriers persist particularly concerning the governance of a local ecosystem of actors. We identify that a facilitating public policy framework combined with internal institutional, strategic and operational drivers linked to the governance of local ecosystems is crucial...
Cette note a pour but de présenter de manière synthétique les modèles mathématiques utilisés aujourd’hui par la communauté des économistes du climat et leurs limites. Ces modèles sont utilisés à la fois pour dimensionner les mesures à prendre pour limiter le changement climatique et pour évaluer les impacts du changement climatique sur le système...

This paper explores the potential contribution of Sustainability-linked Money Creation (SMC) to sustainable economic policies. Our simulations suggest that, in comparison to a baseline scenario, SMC issues could potentially constitute an anti-inflationary, counter-cyclical green transition policy, that increases biomimetic resilience and contains income and wealth inequalities. We finally discuss the policy implications, as well...
We analyze the impact of agricultural productivity growth on tropical deforestation. Our dynamic model of forest-to-farmland, addressing the Jevons’ paradox and Borlaug hypothesis, predicts that rising agricultural productivity, reflected by declining fertilizer price growth, has an ambiguous effect on deforestation. Using tropical forest loss data (2000-2022) and fertilizer price variations, we find a negative...
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...

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.
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...
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.
