Optimal tax theory has diffculty rationalizing high marginal tax rates at the upper end of the income distribution. In this paper, I construct a model of optimal income taxation in which agents' preferences are interdependent. I derive a simple expression for optimal taxes that accommodates...

We derive a general optimal income tax formula when individuals respond along both the intensive and extensive margins and when income effects can prevail. Individuals are heterogeneous across two dimensions: their skill and their disutility of participation. Preferences over consumption and...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We study Pareto optimal tax and education policies when human capital upon labor market entry is endogenous and individuals face wage uncertainty. Though optimal labor distortions are history-dependent, i.e. depend on income and education, simple policy instruments can yield the desired...

This paper surveys possible motivations for having a net wealth tax. After giving a short overview over the state of wealth taxation in OECD countries, we discuss both popular arguments for such a tax, as well as economic arguments. It is argued that classical normative principles of taxation...

We study optimal tax and educational policies in a dynamic private information economy, in which ex-ante heterogeneous individuals make an educational investment early in their life and face a stochastic wage distribution. We characterize labor and education wedges in this setting analytically...

This paper develops a simulation model in order to examine the effectiveness of state attempts at redistribution under a variety of migration elasticity assumptions. Key outputs from the simulation include the impact of tax-induced migration on state revenues, excess burden, and fiscal...

Income tax systems in some countries follow primarily schedular models that classify income by type, match it with deductions from the same class, and compute a separate tax on each class. The United States income tax uses a global tax model under which it taxes citizens and permanent residents...

We study the optimal design of means-tested transfers and progressive income taxes. In a simple analytical model, we demonstrate an optimally negative relation between transfers and income-tax progressivity due to efficiency and redistribution concerns. In a rich dynamic model, we quantify the...

Since 1980, there has been a steady increase in earnings inequality alongside rapid technological growth in the U.S. economy. To what extent does technological change explain the observed increase in earnings dispersion? How does it affect the optimal progressivity of the tax system? To answer...
