In this paper, we explore the proposition that the optimal capital income tax is zero using an overlapping generations model. We prove that for a large class of preferences, the optimal capital income tax along the transition path and in steady state is non-zero. For a version of the model...

This paper studies the role of intangible capital investment in the timing of optimal capital income tax reforms. Within an infinitely lived worker-capitalist model as in Judd (J Public Econ 28:59-83, 1985), we consider two different economies: one in which capitalists devote physical...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

We develop a model for analyzing the sovereign debt crises of 2010 and 2011 in such European countries as Greece, Ireland, and Portugal. The government sets its expenditure-debt policy optimally given a fixed probability of a recovery in fiscal revenues. In doing so, the government can optimally...
