his paper studies the adoption of clean technology in an oligopolistic setting, focusing on carbon capture and storage (CCS) in the cement sector. Firms can choose between two technologies: a carbon- intensive ("dirty") technology and a low-carbon ("clean") one.
Globally, the transport sector is the second-largest source of CO2 emissions, with private road transportation accounting for the majority of these emissions. In this study, we use a structural model and a novel dataset of the French new and used car markets to estimate the determinants of private car demand and price sensitivity. Our findings...
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.
The world economy is not anymore a multipolar world, but clearly tends towards a bipolar one since the global trade war launched by Donald Trump with a major confrontation between US and China. For the future the four European scenarios presented are unequally likely or desirable.
This article examines the financial performance of French solidarity-based investment funds, also known as "90-10 funds", which combine 90% responsible listed assets and 10% solidarity assets from Social and Solidarity Economy (SSE) enterprises.
Hydrogen valleys, which integrate renewable energy sources, hydrogen infrastructure, and end-use applications, play a crucial role in decarbonizing industrial energy hubs. However, the large-scale deployment of hydrogen is constrained by limited renewable electricity availability and high technology costs. A key insight from our analysis is that the merit order of hydrogen end-uses is dynamic, evolving...
Grass-based beef cattle production systems are generally perceived as beneficial to the environment. However, the climate impact of grass-based systems compared to systems based on energy-dense feeds remains controversial. The findings highlight potential trade-offs between climate goals and other sustainability objectives (e.g., biodiversity, animal welfare).
The recent inclusion of second-hand EV subsidies in several countries raises questions about their economic rationale. Contrary to conventional thinking, we show that while subsidies for second-hand EVs are often justified on equity grounds, they also improve efficiency as they influence the equilibrium composition of the vehicle fleet.
This paper studies climate-related central bank communication using a novel dataset containing 35,487 speeches delivered by 131 central banks from 1986 to 2023. It employs natural language processing techniques to identify and trace the evolution of key climate-related narratives centred around (i) green finance, and (ii) climate-related financial risks. Equity returns of "green" firms outperform those of "dirty" firms...

La crise climatique est source de risques financiers désormais reconnus comme porteurs d’incertitudes multiples, et susceptibles de détériorer l’équilibre du système comme celui de ses acteurs.
Ce séminaire sera l’occasion d’aborder plusieurs questions stratégiques soulevées par les risques climatiques tant pour les banques que pour les autorités de tutelle.
