This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

This paper investigates the impact of financial incentive programs, which have become an increasingly common component of welfare programs. We review experimental evidence from several such programs. Financial incentive programs appear to increase work and raise income (lower poverty), but cost...

A substantial literature addresses the design of transfer programs and policies, including the negative income tax, other means-tested transfers, the earned income tax credit, categorical assistance, and work inducements. This work is largely independent of that on the optimal nonlinear income...

The Self-Sufficiency Project (SSP) is a large scale social experiment being conducted in Canada to evaluate the effects of an earnings supplement (or subsidy) for long-term welfare recipients who find a full-time job and leave income assistance. The supplement is available to single parents who...

Various authors, notably Eaton and Rosen (1980a) and Varian (1980), have proposed that income taxation may be justified to some extent on the ground that it serves as social insurance against uncertainties in labor income. They assume that private insurance is unavailable. primarily because of...

In this paper we compare the implications of a symmetric information contracting model and a dynamic labor supply model for changes in individual earnings and hours over time. The critical distinction between these models is whether earnings represent optimal consumption or payment for current...

When wage contracts are relatively short-lived, rent sharing may reduce the incentives for investment since some of the returns to sunk capital are captured by workers. In this paper we use a matched worker-firm data set from the Veneto region of Italy that combines Social Security earnings...

Substantial evidence suggests that savings behavior may depart from neoclassical optimization. This article examines the implications of raising the savings rate - whether through social security, retirement plans, or otherwise - for labor supply, where labor supply is determined by behavioral...

Immigration is often viewed as a proximate cause of the rising wage gap between high- and low-skilled workers. Nevertheless, there is controversy over the appropriate framework for measuring the presumed effect, and over the magnitudes involved. This paper offers an overview and synthesis of...

Myopia is increasingly believed to be a significant determinant of behavior and also plays a central role in justifications for social security and policies toward the taxation of capital. It is important, however, to account for labor supply effects, particularly in light of the preexisting...
