Several frictions restrict the government's ability to tax assets. First, it is very costly to monitor trades on international asset markets. Second, agents can resort to nonobservable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high. This...

We develop a unifying framework for optimal income taxation in multi-activity economies with general production technologies. Agents are characterized by an N-dimensional skill vector that captures intrinsic abilities in N activities. The private return to each activity depends on individual...

Recent estimates of the marginal cost of public funds differ substantially. Some studies argue that the efficiency cost of taxation counter the welfare gain connected to redistribution of income. Hence, the efficiency cost of taxation should not be included as a cost of public goods provision....

This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of across-income heterogeneity in preferences, inheritances, income-shifting capabilities, and other sources. We study unrestricted tax systems on income and...

This paper introduces an index of tax optimality that measures the distance of a current tax structure from the optimal tax structure in the presence of public goods. In doing so, we derive a [0, 1] number that reveals immediately how far the current tax configuration is from the optimal one...

This paper studies the interstate effects of decentralized taxation and spending when individuals can work from home (WFH). Because WFH decouples population and employment, the analysis of tax impacts on state populations, employment levels, wages and housing prices is radically different than...

Taking a piecemeal tax reform approach to tax analysis in the spirit of Feldstein (1976), we establish a framework for assessing perturbations of the income tax schedule. It decomposes a reform into a change in tax level and a structural reform part. Focussing on the latter, the analysis singles...

The paper discusses the tax treatment of commuting where wages and housing cost vary across locations. An income tax distorts the locational choices of agents, who dislike commuting and have preferences for place of residence Wages, housing cost and commuting cost determine how subsidising or...
