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. 

Economic policy efficiency and recovery in an open economy

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

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.

Economic rationality, ecological rationality and the orientation issue

2023
Authors :
Hadrien Lantremange

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...

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.

This thesis highlights the complex relationships between electrification, deforestation, and economic development in developing countries.

Pricing Congestion to Increase Traffic: The Case of Bogotá

2024
Authors :
Juan-Pablo Montero, Felipe Sepúlveda, Leonardo J. Basso

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.
