Bioenergies from dedicated crops or wood have faced substantial criticisms due to their significant land requirements. Certain bioenergy pathways, such as biogas generated from crop residues, manure, or food waste, appear to be exempt from this criticism. However, these feedstocks are byproducts of agricultural activities that generate emissions not covered by current climate policies in...
This paper studies the long-term consequences of a zero-growth regime on the evolution of employment and unemployment, depending on the assumptions we can make concerning the evolution of the working population, labor productivity and working hours. These consequences are examined through three scenarios. This leads us to conclude that the goal...
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...
This paper explores the implications of ecosystemic macroprudential regulations on sustainability in an ecological PK-SFC framework. The results of the paper highlight the relevance of ecosystemic prudential regulation to tackle climate change and call for adopting a holistic approach to sustainability policies.
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...
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...
Ce séminaire porte sur la finance solidaire et la finance à impact qui sont considérées comme des modes de financement alternatifs ou complémentaires aux circuits financiers traditionnels. Il interroge en particulier l’évolution de ces deux types de finances au regard de leurs objectifs affichés, étant donné leur essor important depuis une quinzaine d’années.
This one-day workshop brings together researchers working on the design, evaluation, and impact of climate policies aimed at fostering the development and diffusion of low-carbon technologies. The presentations will cover a range of topics including the regulation of urban transport emissions, the integration of carbon dioxide removal into energy markets, the strategic adoption of...
