We analyze the effect of a Chilean school reform that lengthened the school day from half to full-day shifts on the likelihood that adolescents engage in risky behaviors. By increasing the number of hours spent in school, the reform curtails opportunities to engage in risky behaviors that may...

This paper analyzes Thailand's 2001 healthcare reform, "30 Baht." The program increased funding available to hospitals to care for the poor and reduced copays to 30 Baht (~$0.75). Our estimates suggest the supply-side funding of the program increased healthcare utilization, especially among the...

Whether user fees for health services should be charged or abolished for the poor has recently been debated. This study examines the impact on child health status of removing user fees in South Africa. Our main innovation is to exploit plausibly exogenous variation in access to free health care,...

We report an experiment in 3,000 villages that tested whether incentives improve aid efficacy. Villages received block grants for maternal and child health and education that incorporated relative performance incentives. Subdistricts were randomized into incentives, an otherwise identical...

In this paper, we examine whether a friend or older sibling's teen pregnancy impacts one's own sexual behavior. We exploit high-frequency data on sexual activity from the National Longitudinal Study of Adolescent to Adult Health and the sharp timing of the end of a peer's pregnancy to analyze...

Firearm violence is a pervasive public health crisis in the United States, with significant numbers of homicides involving firearms, including indiscriminate shootings in public spaces. This paper investigates the largely unexplored consequences of stress induced by these attacks on newborn...

This paper uses birth records from California and mothers who move to quantify the absolute and relative importance of birth location in early-life health. Using a model that includes mother and location fixed effects, we find that moving from a below- to an above-median birth weight location...

Low-performing, high-poverty, public schools notoriously struggle to attract and retain good teachers. This paper studies a setting where independent organizations, including charities and businesses, take over the management of under-performing schools, while funding remains public. Exploiting...

In light of the recent rise in childhood obesity, the School Breakfast Program (SBP) and National School Lunch Program (NSLP) have received renewed attention. Using panel data on over 13,500 primary school students, we assess the relationship between SBP and NSLP participation and (relatively)...

I use the Medicare Part D prescription drug insurance market to examine the dynamics of firm interaction with consumers on an insurance exchange. Enrollment data show that consumers face switching frictions leading to inertia in plan choice, and a regression discontinuity design indicates...
