This paper studies optimal fiscal policy in a climate economy model with heterogeneous agents and distortionary taxes on labor and capital income. We derive optimal tax rules and show how they are modified relative to first-best and relative to the case without heterogeneity. We also explore...

An original method to find the shape of favored redistributions is presented, which is in turn used to assess the political acceptability of the optimal tax theory. Two surveys have been conducted in 2016 to quantify French preferences for income redistribution. In the first survey, respondents...

I intend to include a consideration apparently omitted by the optimal tax theory, at least as exposed in the seminal paper [#Saez2001]: demand side. Indeed, according to Keynesianism, as the marginal propensity to save of rich households is significantly above that of poor ones, a redistribution...

Livestock is known to play a significant role in climate change and to negatively impact global nitrogen cycles and biodiversity. However, economically efficient policies for regulating meat production and consumption are under-researched. In the absence of first-best policy instruments for the...

Imperfect altruism between generations may lead to insufficient capital accumulation. We study the welfare consequences of taxing the rent on a fixed production factor, such as land, in this setting. We prove that taxing the rent is welfare-enhancing as it increases capital investment. This...

Financing productive public capital through distortionary taxes typically creates a trade-off: the optimal investment is determined as a compromise between efficiency-enhancing public investment and perturbing market efficiency, but is never socially optimal. In contrast, such a trade-off can...
