Functionalism in ecology and economics: Epistemological affinities and temptations

2024
Authors :
Hadrien Lantremange

This article reviews the epistemological debates about functionalism in ecology. While identifying current area of scientific validity, t emphasizes, in particular, that functionalism depends on the system examined and remains inapplicable wherever singularity prevails. 

Climate change and biodiversity loss: new territories for financial authorities

2024
Authors :
Hugues Chenet

We analyse the current and possible ways forward in this consideration of climate and biodiversity by finance, highlighting the extent to which they may either contribute to and/or suffer from those environmental changes.

Mitigating greenhouse gas emissions from the cattle sector: land-use regulation as an alternative to emissions pricing

2023
Authors :
Maxence Gérard, Stéphane De Cara, Guy Meunier

We examine the efficiency of a subsidy to cattle farmers for setting aside land for natural ecosystem regeneration. We develop a partial equilibrium model of the cattle sector that integrates land use, greenhouse gas emissions, and animal feeding. We identify conditions under which the subsidy is the best alternative to these other second-best policies.

Macroeconomic policy evaluation in an SFC econometric model: the case of the investment program for climate action in France

2024
Authors :
Chin Yuan Chong, Jacques Mazier, Luis Reyes

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.

Leaving the hearth you know: Internal migration and energy poverty

2024
Authors :
Johanna Choumert-Nkolo, Leonard le Roux

We document the relationship between rural–urban migration and energy poverty in South Africa. Our findings show that migrants to urban areas experience significant reductions in energy poverty, particularly in the use of traditional cooking fuels. Our study also explores energy poverty outcomes for both sending and receiving households, gender differences among migrants, and other amenities.

Challenges in measuring the distribution of carbon footprints: The role of product and price heterogeneity

2024
Authors :
Mathias André, Alexandre Bourgeois, Emmanuel Combet, Matthieu Lequien, Antonin Pottier

The distribution of the footprint within a country is regularly computed using consumption data, and with the assumption that the footprint from a product category is proportional to the spending on that product. Here, we explore the limitations of this proportionality assumption.

Emerging consensus on net energy paves the way for improved integrated assessment modeling

2023
Authors :
Louis Delannoy, Matthieu Auzanneau, Baptiste Andrieu, Olivier Vidal, Pierre-Yves Longaretti, Emmanuel Prados, David J. Murphy, Roger W. Bentley, Michael Carbajales-Dale, Marco Raugei, Mikael Höök, Victor Court, Carey W. King, Florian Fizaine, Pierre Jacques, Matthew Kuperus Heun, Andrew Jackson, Charles Guay-Boutet, Emmanuel Aramendia, Jianliang Wang, Hugo Le Boulzec, Charles A.S. Hall

Extracting, processing, and delivering energy requires energy itself, which reduces the net energy available to society and yields considerable socioeconomic implications. Yet, most mitigation pathways and transition models overlook net energy feedbacks.

Inflation and how to deal with it in France. A policy perspective from an empirical stock-flow model

2023
Authors :
Jacques Mazier, Luis Reyes, Chin Yuan Chong

Using an empirical stock-flow consistent (SFC) model for the French economy, we simulate an imported inflationary shock to emulate the current inflation situation and analyze the resulting macroeconomic impacts on the French economy. Two possible responses are considered: increased wage per capita so as to preserve workers’ purchasing power, increased margins by firms in order to restore their...

Enjeux climatiques et gouvernance d’entreprise : Analyse des indices FTSE100, HDAX et SBF120

2023
Authors :
Cécile Cézanne, Yves Kassi, Sandra Rigot

This article analyses the integration of climate issues into corporate governance. Based on data from the 2019 CDP survey, it shows that FTSE100, HDAX, and SBF120 companies use similar control and incentive mechanisms to ensure the transparency of climate information, despite some specificities related to their legal and institutional environments. The paper identifies some shortcomings and makes recommendations to...

Decarbonization with Induced Technical Change: Exploring the Niche Potential of Hydrogen in Heavy Transportation

2024
Authors :
Albin Kasser, Elodie Le Cadre Loret, Guy Meunier, Jean-Pierre Ponssard, Mures Zarea

Electric batteries and fuel cells (hydrogen) are competing technologies for the energy transition in heavy transportation. This paper shows that the existence of a market niche for fuel-cell electric buses (FCEBs) can be obtained depending on the values of a limited set of key parameters.
