We build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work. We find that changes in taxes have large aggregate effects on hours of...

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....

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...

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...

We develop and estimate a static model of labor supply that can account for two robust features of the cross-sectional distribution of usual weekly hours and hourly wages. First, usual weekly hours are heavily concentrated around 40 hours, while at the same time a substantial share of total...

We study business cycle fluctuations in heterogeneous-agent general equilibrium models that feature both intensive and extensive margins of labor supply. A nonconvexity in the mapping between time devoted to work and labor services combined with idiosyncratic shocks generates operative extensive...

I analyze two extensions to the standard model of life cycle labor supply that feature operative choices along both the intensive and extensive margin. The first assumes that individuals face different continuous wage-hours schedules. The second assumes that all work must be coordinated across...

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...

Commonly used frictional models of the labor market imply that changes in frictions have large effects on steady state employment and unemployment. We use a model that features both frictions and an operative labor supply margin to examine the robustness of this feature to the inclusion of a...

We develop a simple model featuring search frictions and a nondegenerate labor supply decision along the extensive margin. The model is a standard version of the neoclassical growth model with indivisible labor with idiosyncratic shocks and frictions characterized by employment loss and...
