Market-Based deployment of Engineered Carbon Dioxide Removal Technologies in Europe
N° 165 – February 2026 [ RECHERCHE ]
Romain Presty
The article develops a multi-country equilibrium model to assess how engineered carbon removals (BECCS and DACCS) can be integrated into the EU Emissions Trading System (ETS). The goal is to understand what this implies for volumes, prices, technology mix, and the geographic distribution.

Explaining Green Excess Returns in the Stock Market: A Five-Factor Model Approach
N° 162 – February 2025 [ RECHERCHE ]
Wang Heda, Arash Farnoosh and Tang Jingyea
The study examines stocks in the new energy, energy-saving, and environmental protection industries to explain green excess returns in the case of Chinese stock market. The green four-factor model is constructed by introducing the green factor based on the Fama-French three-factor model. Empirical results show that this model better explains the risk-return of green concept stocks compared to the three-factor model by verifying the existence of green excess returns, though its explanatory power still needs improvement. Therefore, the study uses stock turnover rate and the firm's return on investment as indicators of the sentiment factor and the efficiency factor, respectively, from the perspectives of green investment sentiment in behavioral finance and positive externalities in microeconomics. The green five-factor model is then constructed by introducing the green sentiment factor and green efficiency factor. Empirical results show that the green five-factor model better interprets the risk-return of green concept stocks compared to the three-factor model and the green four-factor model, with the green sentiment factor and green efficiency factor having a significant positive effect on the return of green concept stocks.

The Performance of China Green Funds around the COVID-19: A Comparative Study with Black Funds and Conventional Funds
N° 161 – December 2024 [ RECHERCHE ]
Wang Heda, Arash Farnoosh and Wang Zhen
The analysis covers 102 green funds, 64 black funds, and 434 conventional funds in China, comparing their performance over 93 sample intervals from November 2015 to July 2023. The performance of green and black funds is significantly higher than that of conventional funds over the entire sample period, primarily due to the greater impact of COVID-19 on the industries in which conventional funds invest. Notably, green funds outperform black funds. When dividing the sample period at the onset of COVID-19, it is found that conventional funds generally outperform green and black funds before the pandemic, while green and black funds significantly outperform conventional funds during COVID-19. After COVID-19, as the state promotes economic recovery, conventional funds again outperform green and black funds. Overall, the performance of green funds gradually improves over time, with increased investment in large-cap and growth stocks.

The rise and fall of Neoliberalism: an ecological and regulationist analysis of France (1960-2022)
N° 160 – June 2024 [ RECHERCHE ]
Alban Pellegris and Victor Court
In this article, we enrich Regulation Theory with metrics from ecological economics: thermodynamic efficiency, exosomatic metabolic rate and the weight of energy expenditure relative to GDP. Then, we use this framework to analyze French capitalism since 1960.
