This paper develops linear estimators for structural and causal parameters in nonparametric,nonseparable models using panel data. These models incorporate unobserved, time-varying, individual heterogeneity, which may be correlated with the regressors. Estimation is based on an approximation of...

This paper compares early childhood enrichment programs that promote social mobility for disadvantaged children within and across generations. Instead of conducting a standard meta-analysis, we present a harmonized primary data analysis of programs that shape current policy. Our analysis is a...

The Global Repository of Income Dynamics (GRID) is a new open-access, cross- country database that contains a wide range of micro statistics on income inequality, dynamics, and mobility. It has four key characteristics: it is built on micro panel data drawn from administrative records; it fully...

We measure the impact of the initial Indian national COVID-19 lockdown on digital activity using browser histories of 1,094 individuals, spanning over 31.5 million website visits on computers and mobile devices. Reflecting the predicted increase in the value of online activity, both men and...

In theory, unilateral divorce laws alter the private incentive to invest in human capital by permitting either spouse to initiate the division of the marital assets. Using several causal research designs we show that both men and women are less likely to attain a bachelor's degree in states with...

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 provide new evidence that cash transfers following the birth of a first child can have large and long-lasting effects on that child's outcomes. We take advantage of the January 1 birthdate cutoff for U.S. child-related tax benefits, which results in families of otherwise similar children...

The composition and quality of the child care workforce may be uniquely sensitive to changes in the complementarities between home production and market work. This paper examines whether the expansion of oral contraceptives and abortion access throughout the 1960's and 1970's influenced the...

This paper asks whether universal pre-kindergarten (UPK) raises parents' earnings and how much these earnings effects matter for evaluating the economic returns to UPK programs. Using a randomized lottery design, we estimate the effects of enrolling in a full-day UPK program in New Haven,...

We incorporate pollution exposure into Becker's "Quantity-Quality" (Q-Q) model of fertility and quantify how air pollution distorts individuals' fertility behaviors in China. We document a robust pattern in which increased pollution over time negatively affects the fertility of ethnic Han...
