This article addresses the modern optimal tax progressivity literature, which clarifies the key
role of the behavioral response to taxation and accounts for the incomes of the superrich …

Using a quantitative model that features technical progress in automation and endogenous
skill choice, we show that, given the current US tax system, a sustained fall in automation …

I study the optimal taxation of robots, other capital, and labor income. I show that it is optimal
to distort robot adoption. The robot tax (or subsidy) exploits general-equilibrium effects to …

We study the incidence of nonlinear labor income taxes in an economy with a continuum of
endogenous wages. We derive in closed form the effects of reforming nonlinearly an …

How are optimal taxes affected by superstar phenomena? To answer this question, we
extend the Mirrlees model to incorporate an assignment problem in the labor market that …

We study reforms of nonlinear income tax systems from a political economy perspective. We
present a median voter theorem for monotonic tax reforms, reforms so that the change in the …

This paper analyses optimal corrective taxation and optimal income redistribution. The
Pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to …

In an ideal world, governments would be able to completely verify all relevant economic
outcomes and characteristics of taxpayers at zero cost. In such a world, non-distortionary …

We develop a framework to study optimal sector-specific taxation, where each agent
chooses an occupation by comparing her skill differential with the tax burden differential …

We study the immigration policy that maximizes the welfare of the native population in an
economy where the government designs an optimal redistributive welfare system and …
