Energy Poverty has a justice dimension: comparing Bolivia, Côte d’Ivoire, and France

2024
Auteurs :
Anna Creti, Alpha Ly et Maria-Eugenia Sanin.

Energy poverty is a multidimensional issue, as demonstrated by a comparison between two low-income countries, Bolivia (BOL) and Côte d’Ivoire (CIV), and a high-income European country, France (FRA). These three countries represent different stages of access and energy poverty. The findings highlight the importance of considering affordability in efforts to ensure universal energy access, to...

2025
Auteurs :
Aubert, N., Couppey-Soubeyran, J., Didier, R., Dufrêne, N., Hollandts, X., Lagoarde-Ségot, 1 T., Le Quang, G., Le Poder, L., Massa, I., Mathieu, A., Peters, A., Ponsot, J.F., Revelli, C., Scialom, L., Sersiron, A., Toure, S., Van Weeren, M.

The report attempts to respond to the UN Secretary-General's recent call for "innovative approaches and bold policy decisions" to tackle the SDGs (UN, 2023). It attributes the existing finance gap to the unrealistic assumptions of the dominant macroeconomic paradigm, which it proposes to replace with new assumptions that are better able to address the...

Groundwater, climate change and conflict: Empirical Evidence from Africa

2024
Auteurs :
Mathieu Couttenier, Remi Jedwab, Lucile Laugerette

Groundwater plays a critical role in supporting economic activities in Africa, particularly in regions affected by climate change-induced water scarcity. This study examines the economic implications of groundwater in relation to conflict dynamics in these regions. The findings underscore the need for developing equitable water management strategies to mitigate conflict and promote sustainable
development...

What policy mix for the ecological transition?

2024
Auteurs :
Esther Jeffers, Dominique Plihon

This article looks at how to make fiscal, monetary and prudential policies greener in order to address the massive financing needs and major risks associated with climate change.

Starting with the observation, based on the recent experience of the financial and health crises, that the separate and independent implementation of monetary and fiscal policies undermines...

Long-term sustainability of zero-growth capitalism: activity, employment and unemployment according to different modes of income distribution

2025
Auteurs :
Laurent Cordonnier, Jacques Mazier

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 modèles IAMs et leurs limites

Auteurs :
Alain Grandjean

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...

Sustainable economic policies: exploring the effects of sustainability-linked money creation

2024
Auteurs :
Augustin Sersiron, Jézabel Couppey Soubeyran, Thomas Lagoarde-Ségot

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...

Agricultural Productivity Growth and Deforestation in the Tropics

2024
Auteurs :
Mathieu Couttenier, Sebastien Desbureaux, Raphael Soubeyran

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...
