This paper exploits a unique ongoing experiment to analyze the effects of early rearing conditions on physical and mental health in a sample of rhesus monkeys (Macaca mulatta). We analyze the health records of 231 monkeys which were randomly allocated at birth across three rearing conditions:...

Pediatricians should consider the costs and benefits of preventing rather than treating childhood diseases. We present an integrated developmental approach to child and adult health that considers the costs and benefits of interventions over the life cycle. We suggest policies to promote child...

We report on a large randomized controlled trial of hospital insurance for above-poverty-line Indian households. Households were assigned to free insurance, sale of insurance, sale plus cash transfer, or control. To estimate spillovers, the fraction of households offered insurance varied across...

We present evidence on the health impacts and mechanisms of a large expansion in non-contributory health insurance in Mexico. The Seguro Popular (SP) was rolled out in 2002-2010 across municipalities, providing exogenous variation in access to health services without co-pays. Our intent-to-treat...

Building on early animal studies, 20th-century researchers increasingly explored the fact that early events - ranging from conception to childhood - affect a child's health trajectory in the long-term. By the 21st century, a wide body of research had emerged, incorporating the original "Fetal...

An open question in the literature is whether families compensate or reinforce the impact of child health shocks. Discussions usually focus on one dimension of child investment. This paper examines multiple dimensions using household survey data on Chinese child twins whose average age is 11. We...

Birth weight is the most widely used indicator of neonatal health, mainly because it is routinely recorded in birth registries. But are better measures available? We use unique data including fetal ultrasounds to show that more specific measures of the fetus and of the newborn are more...

Birth weight is the most widely used indicator of neonatal health. It has been consistently shown to relate to a variety of outcomes throughout the life cycle. Lower birth weight babies have worse health and cognition from childhood, lower educational attainment, wages, and longevity. But what's...
