Childhood vaccines can increase population growth in the short term by improving the survival rates of young children. Over the long run, reductions in child mortality rates are associated with lower demand for children and fertility rates (known as “demographic transition”). Vaccines can...

This paper presents the first estimates of the causal effect of facilities for prenatal sex diagnosis on the sex ratio at birth in India. It conducts a triple difference analysis across cohort, birth order and sex of previous births. Treated births are those that occur after prenatal sex...

The demographic transition the move from a high fertility/high mortality regime into a low fertility/low mortality regime is one of the most fundamental transformations that countries undertake. To study demographic transitions across time and space, we compile a data set of birth and death...

Response rates to important surveys used in social science research have been falling precipitously over the last few decades, raising questions about the representativeness of the resulting data and the quality of evidence that comes from it. We examine how partisan preferences influence...

This paper assesses the causal impact of greater market access on demographic transition during the latter half of the 19th century in the United States. We construct new measures of fertility changes and measures of railroad access at the county level from 1850 1890. We are able to document...

This paper analyzes the impact on age group wage differentials in a setting of imperfect labor substitution at different ages (years) of working life. We examine the wage prospect of assuming medium, high, and low levels of fertility during the population projection period (2020-2090). Main...

This study explores the effects of imbalances in the sex ratio, and their impact on intra-household bargaining, on both the quantity and the quality of children. We first present the theoretical model of intra-household bargaining in the presence of conflicting family goals within a couple, and...
