Governance Arrangements for Local Sustainable Business Models: The Case of Local Energy Systems

2024
Authors :
Johanna Ayrault, Farah Doumit, Franck Aggeri

Despite extensive research on sustainable business models and the development of various tools to facilitate their implementation, barriers persist particularly concerning the governance of a local ecosystem of actors. We identify that a facilitating public policy framework combined with internal institutional, strategic and operational drivers linked to the governance of local ecosystems is crucial...

Les modèles IAMs et leurs limites

2024
Authors :
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
Authors :
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...

Sustainable economic policies: exploring the effects of ecosystemic macroprudential regulations

2024
Authors :
Thomas Lagoarde-Ségot, Gaëtan Le Quang , Laurence Scialom,

This paper explores the contribution of ecosystemic macroprudential regulations to the sustainable development goals in an ecological PK-SFC framework. The results highlight the importance of a paradigm shift in prudential regulation in the fight against climate change.

Agricultural Productivity Growth and Deforestation in the Tropics

2024
Authors :
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...

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...

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.

Inequality and social unrest in India

2023
Authors :
Mathieu Couttenier, Jeremy Laurent-Lucchetti and Lore Vandewalle

We show that inequality triggers social unrest in rural India. We develop a theoretical framework where social unrest is rationally used by civilians to oppose (unfair) surplus sharing by the elite. 

Do French firms follow a transparent or climate-friendly path?

2021
Authors :
Jeanne Amar, Samira Demaria, Sandra Rigot

Our analysis of the Climate Risks and Opportunities Index (CRORI) and the CDP climate score reveal a parallel improvement of these indices with different sectoral disparities over the 2015–2019 period. While our results are encouraging, they need to be put into perspective because these firms are still far from being carbon neutral.
