In economic analyses of the effects of tax policies, one commonly encounters discussions of the equivalence of apparently different policies, where equivalence is defined as the policies having the same impact on fundamental economic outcomes. These related tax policies may differ in many...

We examine a prominent justification for capital income taxation: goods preferred by those with high ability ought to be taxed. In an environment where commodity taxes are allowed to be nonlinear functions of income and consumption, we derive an analytical expression that reveals the forces...

An important proposition in the theory of efficient taxation is that, if capital income is taxed, all types of capital income should be taxed at the same rate. This conclusion has motivated extensive empirical analysis of the tax rates on different types of capital income. It has also been the...

This paper explores the characteristics of individual portfolio holdings in a world economy with a unified securities market where there are many countries, each with its own tax rates and inflation rate. When nominal interest is taxable but income to equity owners is tax exempt in all...

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...

-sigma(s) T(s)c(deltaX(s)), where T(s) measures the present value of the taxes that would be paid on a unit of investment in a riskless project with the same expected depreciation rate and tax treatment as capital invested in period s, X(s), while c(X(s)) represents the certainty equivalent to...

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...

An important result due to Atkinson and Stiglitz (1976) is that differential commodity taxation is not optimal in the presence of an optimal nonlinear income tax (given weak separability of utility between labor and all consumption goods). This article demonstrates that their conclusion holds...
