This paper investigates the effect of entrepreneurs' personal income tax situations on their use of labor. We analyze the income tax returns of a large number of sole proprietors before and after the Tax Reform Act of 1986 and determine how the substantial reductions in marginal tax rates...

This paper provides careful estimates of the impact of removing the deductibility of state and local taxes by state andby income class. We show how deductibility affects marginal and average tax rates for both state and federal tax systems. One striking result is that combined federal income tax...

The two main workhorses of state tax systems are levies on sales and individual incomes. In this paper we develop and implement a coherent methodology for characterizing these systems. The measures thus generated are used to show how the various systems differ across states, and how they evolved...

The issue of tax-induced changes in labor supply behavior has been receiving increasing attention. Economic theory alone can say little about the impact of income taxation on labor supply because of the well- known conflict between income and substitution effects. Therefore, an enormous amount...

Does significant market power or the presence of large rents affect optimal income taxation, calling for greater redistribution due to tainted gains? Or perhaps less because of an additional wedge that distorts labor effort? Do concerns about inequality have implications for antitrust,...

Optimal policy rules--including those regarding income taxation, commodity taxation, public goods, and externalities--are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and...

This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation -- notably, raising revenue, redistributing income, and correcting externalities -- and the mapping between these functions and various...

Should the assessment of government policies, such as the provision of public goods and the control of externalities, deviate from first-best principles to account for distributive effects and for the distortionary cost of labor income taxation? For example, is the optimal extent of public goods...

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...

The marginal social value of income redistribution is understood to depend on both the concavity of individuals' utility functions and the concavity of the social welfare function. In the pertinent literatures, notably on optimal income taxation and on normative inequality measurement, it seems...
