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 17 million births in 72 countries, we...

We investigate women's fertility, labor and marriage market responses to large declines in child and maternal mortality that occurred following a major medical innovation in the US. In response to the decline in child mortality, women delayed childbearing and had fewer children overall. Fewer...

We analyse impacts of the rising labor force participation of women on the gender wage gap. We formulate and structurally estimate an equilibrium model of the labor market in which the elasticity of substitution between male and female labor is allowed to vary depending on the task content of...

There has been a phenomenal global increase in the proportion of women in politics in the last two decades, but there is no evidence of how this influences economic performance. We investigate this using data on competitive elections to India's state assemblies, leveraging close elections to...

Raising women's political participation leads to faster maternal mortality decline. We estimate that the introduction of quotas for women in parliament results in a 9 to 12% decline in maternal mortality. In terms of mechanisms, it also leads to an 8 to 11% increase in skilled birth attendance...

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...

We suggest how contemporary global institutions shaping the development, pricing and distribution of vaccines and drugs may be modified to deliver large improvements in health. To support a justice argument for such modification, we show how the current global economic order may contribute to...

We leverage introduction of the first antibiotic therapies in 1937 to examine impacts of pneumonia in infancy on adult education, employment, disability, income and income mobility, and identify large impacts on each. We then examine how racial segregation in the pre-Civil Rights Era moderated...

This paper investigates why children work by studying the wage elasticity of child labour supply. Incorporating subsistence constraints in to a model of labour supply, we show that a negative wage elasticity favours the hypothesis that poverty compels work whereas a positive wage elasticity...
