The income of Puerto Rican affiliates of U.S. corporations is essentially untaxed by either Puerto Rico or the U.S. This lowers the tax penalty on real investment there, and also makes it attractive to shift reported taxable income from the U.S. parent corporation to the Puerto Rican affiliate....

The standard analysis of the optimal international tax policy of a small country typically assumes that the country either imports or exports capital, but does not do both. This paper considers the situation in which a small country both exports and imports capital and can alter its tax on one...

In 1992, the income tax withholding tables were adjusted so that withholding was reduced. A typical worker received an extra $28.80 in take-home pay per month in March through December 1992, to be offset by a lower tax refund in 1993. The change in withholding amounted to 0.5 percent of GDP....

At the end of 1983 Gallup polls showed that 52 percent of Americans thought that the probability of a world war in the next 10 years was 50% or higher; by 1989 the percentage had dropped to 29%. Fear of war of this pervasiveness is bound to have an effect on decisions about present versus...

It is often claimed that multinational firms avoid taxes by shifting income from high-tax to low-tax countries. Using a five year panel of data for two hundred large U.S. manufacturing firms, we find that U.S. tax liability, as a fraction either of U.S. sales or U.S. assets, is related to the...

We investigate the optimal rate structure of an income tax system that is constrained to have only two brackets, plus a demogrant. We find that, in a two-class economy, Pareto efficient tax schedules feature at least one marginal tax rate equal to zero, and that the marginal tax rate may be...

In this paper we develop some simple models of optimal tax and tariff policy in the presence of global corporations that operate in an imperfectly competitive environment. The models emphasize two important differences in the practical application of tax and tariff policy - tax, but not tariff,...

This paper examines a newly available six-year panel of tax return data to see what light it sheds on the tax elasticity of capital gains realizations. Panel data are a particularly valuable source of evidence for this question, because they can help to distinguish short-run from long-run...

The resource cost of operating the income tax system is large, totaling as much as seven to eight percent of revenue raised. One source of this cost is the system of itemized deductions, which can require extensive record keeping and calculation. This paper estimates the resource cost of...

For most parameter values, increased randomness about how much taxable income an auditor would assess leads to higher reported income and more revenue, When reducing randomness is costly, optimality requires some randomness in assessed taxable Income. Even if reducing randomness g costless,...
