This paper investigates the causal relationship between women's schooling and fertility by exploiting variation generated by the removal of school fees in Ethiopia. The increase in schooling caused by the reform is identified using both geographic variation in the intensity of its impact and...

In developing regions, significant increases in primary school enrollment are often generated by large national level programs, which could simultaneously promote overcrowding and reductions in education quality. In a difference-in-differences framework, this paper exploits geographic variation...

To combat rising item non-response in household surveys for some continuous variables, surveys are increasingly supplementing these questions with categorical responses or “unfolding brackets.” This survey technique is particularly prevalent in health surveys. Using data from four different...

The Silk Roads were a decentralized network of trade routes that connected ancient cities across Eurasia. Goods, ideas, people, and technology moved along the roads for over 1,500 years. Using a detailed georeferenced map of the entire trade network, this paper finds that areas within 50 KM of...

This paper investigates the relationship between women's education and fertility by exploiting a 1985 policy change in Kenya that lengthened primary school by one year.
