The introduction of prenatal sex-detection technologies in India has led to a phenomenal increase in abortion of female fetuses. This paper examines the impacts of this on girl relative to boy mortality rates after birth, using data from 1973-2005. The analysis finds a narrowing of the gender...

We investigate restructuring of the health system in Brazil motivated to operationalize universal health coverage. Using administrative data from multiple sources and an event study approach that exploits the staggered rollout of programmatic changes across municipalities, we find large...

Historically, improvements in the quality of municipal drinking water made important contributions to mortality decline in wealthy countries. However, water disinfection often does not produce equivalent benefits in developing countries today. We investigate this puzzle by analyzing an abrupt,...

We analyze long-term impacts of the 1967-1970 Nigerian Civil War, providing the first evidence of intergenerational impacts. Women exposed to the war in their growing years exhibit reduced adult stature, increased likelihood of being overweight, earlier age at first birth, and lower educational...

We estimate impacts of exposure to an infant health intervention trialled in Sweden in the early 1930s using purposively digitised birth registers linked to school catalogues, census files and tax records to generate longitudinal microdata that track individuals through five stages of the...

Twin births are often construed as a natural experiment in the social and natural sciences on the premise that the occurrence of twins is quasi-random. We present new population-level evidence that challenges this premise. Using individual data for more than 18 million births (more than 500,000...

In this study we examine the passage of a reform to in-vitro fertilization (IVF) procedures in Sweden in 2003. Following publication of medical evidence showing that pregnancy success rates could be maintained using single rather than multiple embryo transfers, the single embryo transfer (SET)...
