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.
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 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.
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...
