Several European governments implemented a generalized gasoline subsidy in the face of inflation following the Ukrainian crisis. In contrast, reducing fossil fuel consumption is crucial to mitigate the current energy and climate crises. Fuel consumption for transport increases with income, making rich households the main beneficiaries of generalized subsidies. In this context, a thorough investigation of the nature of vulnerability to rising gasoline prices is needed to formulate targeted policies.
This PhD thesis focuses on a recent and rapidly spreading, but highly diverse phenomenon: the integration of climate and environemntal issues by central bankers. To do so, the author draws from different approaches in order to understand what drives (some) central banks to embrace this issue, why they do so and how.
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.
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.
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, and the costs of public funds.
The 2008 and Covid crises have led to increasing public debts and to the launching of unconventional economic policies. Thanks to a complete description of the balance sheets of the domestic and foreign agents, stock-flow consistent (SFC) modelling was well equipped to evaluate their economic consequences.

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 success.
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.
The cattle sector, both emissions- and land-intensive, represents a great opportunity for mitigation through reforestation. In this paper, we study the efficiency of land-use regulation. Our analytical results indicate that the subsidy is the best alternative policy to emissions tax, provided that the elasticities of land use and emissions to cattle feeding are close. Interestingly, we show that the optimal meat tax should integrate the carbon opportunity cost of land use.
