What policy mix for the ecological transition?

2024
Authors :
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...

Comment la dimension locale modifie le modèle d’affaires d’une entreprise. Cas des systèmes énergétiques locaux

Les défis rencontrés par les entreprises cherchant à concilier durabilité, création de valeur économique et respect des enjeux environnementaux et sociaux dans nos modèles actuels de consommation et de production sont complexes. Les modèles d’affaires durables émergent comme une solution, mais, selon les activités, leur mise en œuvre est entravée par divers obstacles, comme...

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

2025
Authors :
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

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...

Unravelling the Narratives of the Climate Finance

2024
Authors :
Hugues Chenet, Soline Ralite

Since the early 2000s, the public debate has gradually filled with normative proposals aimed at tackling the two-way climate finance challenge (how finance impacts climate stability and how finance can be impacted by climate change) – the “climate finance agenda”. Yet, although parts of this agenda are already discussed by the literature, scholars still...
