This paper analyzes the quantitative role of idiosyncratic uncertainty in an economy in which rational agents vote on hypothetical social security reforms. We construct an Overlapping Generations economy in which individuals face idiosuncratic risk with respect to their labor productivity and...

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...
