We analyze optimal dynamic taxation when labor supply is indivisible, as in Hansen (1985) and Rogerson (1988). Markets are complete, and an employment lottery determines who works. The consumer can buy insurance to diversify this extrinsic income uncertainty. The optimal wage tax is zero in both...

How should aggregate public expenditures be traded off against their financing costs? We incorporate public expenditures into a standard neoclassical growth setup with model policy choice as made by a government choosing tax rates and spending so that the resulting competitive equilibrium...

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...

In a dynamic optimizing model with costly tax collection, a tax cut by one nation creates positive externalities for the rest of the world if initial public debt stocks are positive. By reducing tax collection costs, current tax cuts boost the resources available for current private consumption,...

We study a setting with search frictions in the marriage market and with incomplete contracting inside the family. Everyone prefers a partner that has a high income and is a perfect emotional match, but compromises must often be struck. A high-income earner may abstain from marrying a low-income...

The Ramsey optimal taxation theory implies that the tax rate on capital income should be zero in the long run. This result holds even if the social planner only cares about workers that do not hold assets, or if the planner only cares about any other group in the economy. This paper demonstrates...

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

In the coming decades, the share of people in working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby-boom generation retires. I find that if debts are instead maintained at the current levels, welfare...

This Paper analyses the optimal timing of taxes on capital income. We show that the celebrated result that taxes should front-loaded with an initially high tax followed by a discrete jump to the steady state is knife-edge, hinging on capital having a constant depreciation rate. An empirically...

We characterize optimal redistribution in a dynastic family model with human capital. We show how a government can improve the trade-off between equality and incentives by changing the amount of observable human capital. We provide an intuitive decomposition for the wedge between human-capital...
