The integration of world capital markets carries important implications for the design and impact of tax policies. This paper evaluates research findings on international taxation, drawing attention to connections and inconsistencies between theoretical and empirical observations. Diamond and...

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...

Recent theoretical work has argued that a small open economy should use residence-based but not source-based taxes on capital income. Given the ease with which residents can evade domestic taxes on foreign earnings from capital, however, a residence-based tax may not be administratively...

This paper examines how rules to determine the source of income internationally for tax purposes can have important effects on the form in which taxable income is reported and on the location of economic activity. In the case of U.S. law, two provisions are significant: allowing a portion of...

We study optimal taxation in a model with endogenous financial frictions, risky investment and occupational choice, where the distribution of wealth across entrepreneurs affects how efficiently capital is used. The planner chooses linear taxes on wealth, capital and labor income to maximize the...

This paper investigates empirically the effects of personal and corporate taxes on taxable interest rates and on the spread between taxable and tax-exempt rates. Two main sets of results emerge. First, we establish that the effective marginal investors in the Treasury bill market are households,...

Since the average tax rate on corporate capital income is very high, economists often conclude that taxes have caused a substantial fall in corporate investment, a movement of capital into noncorporate uses, and a fall in personal savings. The combined efficiency costs of these distortions are...

This paper reviews recent advances in the study of dynamic taxation, considering three main approaches: the dynamic Mirrlees, the parametric Ramsey, and the sufficient statistics approaches. In the first approach, agents' heterogeneous abilities to earn income are private information and evolve...

This paper explores how alternative assumptions about household portfolio behavior affect estimates of the revenue cost of excluding state and local government interest payments from the federal income tax base. Standard tax expenditure estimates assume that current holders of tax-exempt bonds...
