Through tax evasion, through the labour-leisure choice or in other ways, taxpayers reduce the tax base in response to an increase in the tax rate. The process is commonly-believed to generate a humped Laffer curve with a revenue-maximizing tax rate well short of 100%. That need not be so. In the...

We characterize an optimal redistributive pension scheme when individuals face temptation, but can exert costly self-control (as in Gul & Pesendorfer, 2001; 2004). Our results challenge the common wisdom that forced savings tend to reduce individuals' mental cost of self-control. In our model,...

Important as it is for public policy, there is still no consensus about the size of the revenue-maximizing tax rate at the top of the Laffer curve. The purpose of this essay is not to supply a correct rate, but to identify difficulties in doing so. 1) Estimates of the revenue-maximizing tax rate...

It is well-known that cash-flow business taxes with full loss-offset, and their present-value equivalents, are neutral with respect to firms' investment decisions when firms are riskneutral and there are no distortions. We study the effects of cash-flow business taxation when there is bankruptcy...

We characterize optimal income taxation and unemployment insurance in a search-matching framework where both voluntary and involuntary unemployment are endogenous and Nash bargaining determines wages. Individuals differ in utility when voluntarily unemployed (non-participants in the labour...

Despite the fact that all developed economies levy broadly-based indirect taxes alongside direct taxes, little theory is devoted to explaining the direct-indirect tax mix. Our purpose is to show that if different taxes have different evasion characteristics, some optimal tax mix emerges...

Evasion and time inconsistency have been prominent concerns in recent discussions capital income taxation, both theoretical and applied. This paper establishes a link between them, suggesting a potentially useful role for evasion additional to those previously identified: by committing to...

Using the standard nonlinear income taxation framework with heterogeneity of preferences, this paper examines the optimality of workfare as a screening tool. It is assumed that workfare does not serve as a human capital investment, participation is mandatory, and administrative costs are...

We examine whether minimum wages can fulfill a useful role as part of an optimal nonlinear income tax scheme. In this setting, governments cannot observe household abilities, only their incomes. Redistributing according to income, the government is constrained by a set of incentive constraints....

Redistribution programs are constrained because those not working may be either unable to work, voluntarily unemployed or involuntarily unemployed. The inability to distinguish among these three cases inhibits the targeting of transfers to those most in need. Enabling the government to monitor...
