La transition écologique mérite un nouveau contrat social

2023
Authors :
Emmanuel Combet

L’Europe subit depuis 2021 des chocs douloureux sur les prix des énergies qui résultent du cumul de plusieurs facteurs. Ce contexte d’énergie rare et chère est douloureux, mais il donne un signal politique et économique fort : il souligne l’importance de diversifier les approvisionnements pour assurer notre sécurité énergétique et l’intérêt d’une sobriété pour réduire nos...

Crop prices and deforestation in the tropics

2023
Authors :
Nicolas Berman, Mathieu Couttenier, Antoine Leblois, Raphael Soubeyran

Understanding the mechanisms of deforestation is necessary in order to slow or arrest its progress. To accomplish this requires rigorously estimating the demand for deforestation. We contribute to this endeavor by estimating the effect of crop prices on the demand for conversion of land from forest to agriculture in the tropics during the 21st...

Coordination of sectoral climate policies and life-cycle emissions

2023
Authors :
Quentin Hoarau and Guy Meunier

The present paper addresses the issue of sectoral policy coordination, especially when Pigovian carbon pricing is unavailable. It analyzes the optimal allocation of mitigation effort among two vertically connected sectors, an upstream (e.g. electricity) and a downstream (e.g. transportation) one.

Les Futurs en transition : les scénarios

2021-2023
Authors :
Emmanuel Combet

L’ADEME a souhaité soumettre au débat quatre chemins “types” cohérents qui présentent de manière volontairement contrastée des options économiques, techniques et de société pour atteindre la neutralité carbone en 2050. Ce travail a été conduit de 2019 à 2021 et n'est pas remis en cause par les conflits actuels majeurs, bien au contraire. 

Extending the limits of the abatement cost

2021
Authors :
Guy Meunier, Jean-Pierre Ponssard

The paper examines the relevant cost benefit framework for state agencies investigating the potential of local projects to mitigate climate change. We propose a new metric that incorporates into the analytical framework the dynamic interactions between the project and its continuation.

Quantifying GHG emissions enabled by capital and labor: Economic and gender inequalities in France

2023
Authors :
Antonin Pottier, Gaëlle Le Treut

Many studies have investigated the carbon footprint of households. Here we open a new field by discussing the emissions that individuals enable by providing labor and capital to companies, using the framework of income-based (downstream) responsibility. Our results show that inequalities in emissions do not strongly interact with economic inequality. Yet they are gendered...

Over-allocation profits and competition issues in the steel industry

2023
Authors :
Maria-Eugenia Sanin, Sylvain Sourisseau

Sectors that are considered to be subject to international competition under the European Emission Trading Scheme (EU-ETS) still benefit from free allocation of European Allowances (EUAs). Herein we study one of those beneficiaries: the crude steel industry. Our findings suggest the EU-ETS has failed to provide incentives for decarbonization in this sector.

There’s no price signal !

2023
Authors :
Ivar Ekeland, Wolfram Schlenker, Peter Tankov, Brian Wright

We address the long-standing challenge of adding optimal exploration to the classic Hotelling model of a non-renewable resource. We prove that a frontier of critical levels of proven reserves exists, above which exploration ceases, and below which it proceeds at infinite speed.

Attractiveness of Clean Energy Stocks in Europe: The importance of shocks in oil and gas prices

2023
Authors :
Maria Eugenia Sanin, Ayşegül Uçkun Özkan

This article identifies supply and demand shocks in the oil and gas market using monthly data (from January 2008 to December 2021) and explores their impact on clean energy stock returns in Europe. Our results show that a negative gas supply shock positively affects clean energy stocks, while a negative shock in global oil supply does not have...

Access to electricity and children well-being: new evidence from Rwanda

2023
Authors :
Lucien Vignawou Ahouangbe, Ahmed Tritah

In this study, we analyse how access to electricity affects children’s well-being in Rwanda through the allocation of their time in the different activities of domestic production and their leisure time.
