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
économique et financier.
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 as the limitations of our findings.
The publication aims at anwsering the following questions :
This paper advances the issue about the richest people contributing disproportionately to the increase in CO2 emissions, and thus to global warming by providing robust econometric validity. The method aims at. examining the effect of wealth accumulation on carbon emissions. Our regression estimates support the hypothesis that wealth concentration significantly increases carbon inequality and accounts for nearly 20% of the CO2 emissions of the richest people.
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 correlation between fertilizer price growth and deforestation, particularly in regions with high market potential. Our results highlight that protected areas do not mitigate the adverse effects of fertilizer price growth on deforestation.
We analyze the effects of power constraints on manufacturing firms’ TFPR. Statistically, the power constraints treatment variable is not random for the firms. Power constraints negatively and significantly affect firm-level TFPR. Average productivity 11% lower for exposed firms compared to unexposed firms. The acquisition of backup generators or investment in R&D mitigates this effect.
This paper investigates the impact of electrification on household practices related to deforestation in Côte d’Ivoire, specifically focusing on the expansion of arable farms and the use of biomass fuels.
Looking at the relationship between electrification and the expansion of arable farms inspired by Angelsen and studying data from the latest four waves of the household Living Standards Measurement Surveys (1998, 2002, 2008, and 2015), we find that increased access to electricity significantly reduces both the average size of arable farms and the collection of firewood from forests.
Chaque année, le CEPII publie dans la collection » Repères » des analyses inédites des grandes questions économiques mondiales. L’économie mondiale tourne peut-être la page de la Covid-19 ainsi que celle de l’inflation, mais va devoir apprendre à se relever de chocs d’offre, de la géopolitique au climat, appelés à se multiplier, et à naviguer dans un environnement où la sécurité économique redessine le cadre des échanges internationaux. En Europe, en Chine et dans le reste du monde.
Alors que notre époque est marquée par l’urgence climatique, la transition écologique peine à s’enclencher. L’ouvrage plaide pour concerter la transition écologique et engager l’ensemble de la société dans la construction d’un avenir commun. Semblable à un processus constituant, ce changement d’approche vise à construire un nouveau contrat écologique, un compromis de société qui décloisonne les questions sociales, économiques et écologiques.
