It is widely believed that the presence of a large informal sector increases the efficiency cost of social programs - transfer and social insurance programs - in developing countries. We evaluate such claims for policies that have been heavily studied in countries with low informality -...

The Department of Homeland Security estimates that 11.4 million undocumented persons reside in the United States. Congress and President Obama are considering a number of proposals to regularize the status of the undocumented population and provide a "path to citizenship." Any future change in...

We provide the first systematic account of summer declines in women's labor market activity. From May to July, the employment-to-population ratio among prime-age US women declines by 1.1 percentage points, whereas male employment rises; women's total hours worked fall by 9.8 percent, more than...

We study the effects of job-protected leave policies on intergenerational mobility, long-run child outcomes, and parental decisions (labor market, investments in children, and fertility). We merge rich sources of historical information on family leave policies across the United States since 1973...

Employment and participation rates for US prime age women rose steadily during the second half of the 20th century. In the last 30 years, however, those rates stagnated, even as employment and participation rates for women in other industrialized countries continued to rise. I discuss the role...

We provide the first estimates of the negative impact of exposure to extremely high temperatures during pregnancy on mothers' labor market outcomes. We employ individual-level survey data from China and leverage plausibly exogenous fluctuations in heat exposure within cities. The results...

Full days worked at home account for 28 percent of paid workdays among Americans 20-64 years old, as of mid 2023, according to the Survey of Working Arrangements and Attitudes. That's about four times the 2019 rate and ten times the rate in the mid-1990s that we estimate in time-use data. We...

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...

This paper examines the multigenerational impact of children and whether the public provision of formal childcare lessens the earnings and employment impacts of children. We find that the arrival of a firstborn reduces employment and earnings of mothers and employment of grandmothers. Studying a...

This paper is about the nonparametric regression of a choice variable on a nonlinear budget set under utility maximization with general heterogeneity, i.e. in the random utility model (RUM). We show that utility maximization and convex budget sets make this regression three dimensional with a...
