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...

Do high taxes cause superstars to work less? We test this hypothesis using complete data on Hollywood movie stars' labor supply from 1927 to 2014. Changes to marginal tax rates in high tax brackets have no significant effect on the number of films a movie star makes each year. However, in years...

The largest tax-based social welfare programs in the US limit their benefits to taxpayers with labor market income. Eliminating these work requirements would better target transfers to the neediest families but risks attenuating tax-based incentives to work. We study changes in labor force...

We estimate the extensive and intensive margin labor supply response to the monthly Child Tax Credit disbursed in 2021 as a part of the American Rescue Plan Act. Using Current Population Survey microdata, we compare labor supply outcomes among households who qualify for varying relative...

College-educated mothers spend substantially more time in intensive childcare than less educated mothers despite their higher opportunity cost of time and working more hours. Using data from the 2010-2013 and 2021 waves of the Well-being Module of the American Time Use Survey, we investigate...

Billions of women still face legal barriers to economic inclusion, yet it is unclear whether lifting these barriers is sufficient to enhance their economic participation. We conduct a field experiment to quantify the impact of a major legal reform - the lifting of the Saudi women's driving ban -...

We investigate the influence of the growing trend of work-from-home (WFH) on new business formation, with a particular focus on the period surrounding the COVID-19 pandemic. At baseline, local new business entry is positively associated with the proportion of occupations amenable to telework in...

Headline estimates for the extent of work from home (WFH) differ widely across U.S. surveys. The differences shrink greatly when we harmonize with respect to the WFH concept, target population, and question design. As of 2025, our preferred estimates say that WFH accounts for a quarter of paid...

We show that Covid-19 illnesses persistently reduce labor supply. Using an event study, we estimate that workers with week-long Covid-19 work absences are 7 percentage points less likely to be in the labor force one year later compared to otherwise-similar workers who do not miss a week of work...

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...
