Titre : Optimal Fiscal Policy in a Second-Best Climate-Economy model with Heterogeneous Agents

Résumé : This paper studies optimal fiscal policy in a climate-economy model with heterogeneous agents. When individualized lump-sum taxation is not available, distortionary taxes on labor and capital income are levied to provide redistribution. The optimal pollution tax rule is then a modified Pigouvian formula that accounts for tax distortions, with the sign of this adjustment varying over time. In a quantitative analysis where the climate model is calibrated to DICE and the fiscal system to the one of the U.S., we show that tax distortions have a negligible effect on the optimal carbon tax, but inequalities reduce it by 4% in the baseline. Optimal carbon taxation generates moderately negative but progressive welfare effects in the 21st century, large positive but regressive effects thereafter.
