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...

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 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 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....

A political miracle occurred when Germany was reunited, and at first glance an economic miracle has followed. Real incomes in the east have now reached the western level, and investment per capita has been much higher than in the west. However, every third deutschmark spent in the east has been...

This paper develops a theory of intergenerational exchange for generations that are either selfish or have non-dynastic altruism. The main building blocks of the theory are forward and backward intergenerational goods (FIGs and BIGs) and the relationship between them. A FIG is a transfer from...

Among the most important changes brought about by the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) is the imposition of time limits. In this paper, we analyze a simple model in which a potential welfare recipient chooses how to allocate her time-limited...

The purpose of the present note is to explore the structure of optimal income taxation/redistribution in an economy where the welfare of individuals depends in part on relative after-tax consumption, i.e., we specify individual welfare as a function of absolute and relative after-tax...
