In the United States, child support guidelines sometimes generate surprising and presumably unintentional child support amounts, especially in situations with extended visitation, shared parenting, and half-siblings. These are consequences of the ad-hoc mathematical formulas that are in common...

Using data on over 420,000 first time Dutch mothers, we examine the effects of postpartum antidepressant use on a wide range of maternal outcomes including further treatment for severe mental illness, labor market outcomes, and family formation. We exploit rules which state that Dutch general...

How does one's place of residence affect individual behavior and long-run outcomes? Understanding neighborhood and place effects has been a leading question for social scientists during the past half-century. Recent empirical studies using experimental and quasi-experimental research designs...

Using every major nationally-representative dataset on parental and non-parental care provided to children up to age 6, we quantify differences in American children's care experiences by socioeconomic status (SES), proxied primarily with maternal education. Increasingly, higher-SES children...

Using data from all those born in a single week in 1958 in Britain we track the consequences of short pain and chronic pain in mid-life (age 44) on health, wellbeing and labor market outcomes in later life. We examine data taken at age 50 in 2008, when the Great Recession hit and then five years...

We report the labor market effects of the Jamaica Early Childhood Stimulation intervention at age 31. The study is a small-sample randomized early childhood education stimulation intervention targeting stunted children living in the poor neighborhoods of Kingston, Jamaica. Implemented in...

We studied the effect of marijuana liberalization policies on perinatal health with a multiperiod difference-in-differences estimator that exploited variation in effective dates of medical marijuana laws (MML) and recreational marijuana laws (RML). We found that the proportion of maternal...

Books shape how children learn about society and social norms, in part through the representation of different characters. To better understand the messages children encounter in books, we introduce new artificial intelligence methods for systematically converting images into data. We apply...

This study examines the effect of a tightening of the U.S. air-quality standard for lead in 2009 on the relocation of battery recycling to Mexico and on infant health in Mexico. In the U.S., airborne lead dropped sharply near affected plants, most of which were battery-recycling plants. Exports...

The Clean Water Act (CWA) significantly improved surface water quality, but at a cost exceeding the estimated benefits. We quantify the effect of the CWA on a direct measure of health and incorporate health benefits into a cost-benefit analysis. Using a difference-in-differences framework, we...
