Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

The South African old-age social pension has been much studied by both researchers and policy makers, in part for the larger lessons that might be learned about behavioral responses to cash transfers in developing countries. In this paper, we quantify the labor supply responses of prime-aged...

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...

The labor supply and other work incentive effects of welfare programs have long been a central concern in economic research. Work has also been an increasing focus of policy reforms in the U.S., culminating with a number of major policy changes in the 1990s whose intent was to increase...

This paper argues that a key aspect of the US labor market is the presence of time-varying heterogeneity across nonparticipants. We document a decline in the share of nonparticipants who report wanting to work, and we argue that that decline, which was particularly strong in the second half of...

We estimate a dynamic model of employment, human capital accumulation - including education, and savings for women in the UK, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy. We find substantial elasticities for labor supply and particularly for lone...

We document a robust negative relationship between mean annual hours in an occupation and the dispersion of annual hours within that occupation. We study a unified model of occupational choice and labor supply that features heterogeneity across occupations in the return to working additional...

We examine patterns of work in the U.S. from 1973-2018 with the novel focus on days per week, using intermittent CPS samples and one ATUS sample. Among full-time workers the incidence of four-day work tripled during this period, with over 8 million more full-time workers on four-day weeks. The...

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....

Educational subsidies are frequently justified as a method of altering the income distribution. It is thus natural to compare education to other tax-transfer schemes designed to achieve distributional objectives. While equity-efficiency trade-offs are frequently discussed, they are rarely...
