Extracting, processing, and delivering energy requires energy itself, which reduces the net energy available to society and yields considerable socioeconomic implications. Yet, most mitigation pathways and transition models overlook net energy feedbacks.

Inflation and how to deal with it in France. A policy perspective from an empirical stock-flow model

2023
Authors :
Jacques Mazier, Luis Reyes, Chin Yuan Chong

Using an empirical stock-flow consistent (SFC) model for the French economy, we simulate an imported inflationary shock to emulate the current inflation situation and analyze the resulting macroeconomic impacts on the French economy. Two possible responses are considered: increased wage per capita so as to preserve workers’ purchasing power, increased margins by firms in order to restore their...

Enjeux climatiques et gouvernance d’entreprise : Analyse des indices FTSE100, HDAX et SBF120

2023
Authors :
Cécile Cézanne, Yves Kassi, Sandra Rigot

This article analyses the integration of climate issues into corporate governance. Based on data from the 2019 CDP survey, it shows that FTSE100, HDAX, and SBF120 companies use similar control and incentive mechanisms to ensure the transparency of climate information, despite some specificities related to their legal and institutional environments. The paper identifies some shortcomings and makes recommendations to...

Decarbonization with Induced Technical Change: Exploring the Niche Potential of Hydrogen in Heavy Transportation

2024
Authors :
Albin Kasser, Elodie Le Cadre Loret, Guy Meunier, Jean-Pierre Ponssard, Mures Zarea

Electric batteries and fuel cells (hydrogen) are competing technologies for the energy transition in heavy transportation. This paper shows that the existence of a market niche for fuel-cell electric buses (FCEBs) can be obtained depending on the values of a limited set of key parameters.

Unconventional monetary policy in an econometric SFC model of the French economy: Some lessons for financing the low-carbon transition

2023
Authors :
Jacques Mazier, Luis Reyes

Un modèle économétrique SFC de l'économie française est présenté pour étudier les effets des politiques monétaires non-conventionnelles et l'impact d'une version simple de la monnaie électronique banque centrale. Différentes formes de politiques monétaires non conventionnelles sont évaluées.

Dette publique et policy mix climatique : l’éclairage des modèles macroéconomiques stocks-flux cohérents

2023
Authors :
Jacques Mazier, Luis Reyes

This paper examines the contribution of SFC modelling to the definition of a green policy mix that would facilitate the implementation of a climate transition policy.

Technology Neutral vs. Technology Specific Procurement

2023
Authors :
Juan-Pablo Montero and Natalia Fabra

An imperfectly-informed regulator needs to procure multiple units of some good that can be produced with heterogeneous technologies at various costs. How should it optimally procure these units? We find that one size does not fit all: the preferred instrument depends on the costs of the available technologies, their degree of substitutability, the extent of information asymmetry,...

Green industrial policy, information asymmetry, and repayable advance

2023
Authors :
Guy Meunier, Jean‐Pierre Ponssard

Recent recovery plans, associated with the COVID‐19 pandemic and the energy transition, increased the funding available to finance innovative low‐carbon projects and called for an economic evaluation of their allocation. This paper analyzes the potential benefit of using repayable advance: a lump‐sum payment to finance the project that is paid back in case of...

What are the Drivers of Corporates’ climate transparency? Evidence from the S&P 1200 Index

2023
Authors :
Jeanne Amar, Samira Demaria et Sandra Rigot

Climate transparency through firms' disclosures is often considered a prerequisite for the redirection of investments toward low-carbon economy. In order to provide effective incentives to improve this transparency, it is therefore crucial to identify its drivers.
