Building on anthropological evidence, we develop a model of intra-household decision making on fertility and child survival within the framework of the collective household model. We carry out a test of the implications of this framework with data from Demographic and Health Surveys in rural...

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...

Twin births are often used to instrument fertility to address (negative) selection of women into fertility. However recent work shows positive selection of women into twin birth. Thus, while OLS estimates will tend to be downward biased, twin-IV estimates will tend to be upward biased. This is...

Twin births are often construed as a natural experiment in the social and natural sciences on the premise that their occurrence is quasi-random. We present new population-level evidence challenging this premise. Using data on about 18 million births in 72 countries, we find that maternal...

Expansion in access to public infrastructure can have varied, micro-level impacts. In this paper, we use quasi-random access to rural paved roads through a large-scale road-construction program in India to study how road access impacts fertility decisions and investments in child health. We find...

The introduction of prenatal sex-detection technologies in India has led to a phenomenal increase in abortion of female fetuses. We investigate their impact on son-biased fertility stopping behavior, parental investments in girls relative to boys, and the relative chances of girls surviving...

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...
