We assess the impact of large-scale fee elimination for secondary school girls in The Gambia on the quantity, composition, and achievement of students. The gradual rollout of the program across geographic regions provides identifying variation in the policy. The program increased access to...

Informal school fees – for uniforms, books, and other supplies – are substantial in developing countries, often several times formal tuition. We evaluate a scholarship program that alleviated informal fees for girls in a subset of Gambian secondary schools. The program is unique because it...

We provide the first evidence on the causal effect of border enforcement on the full spatial distribution of Mexican immigrants to the United States. We address the endogeneity of border enforcement with an instrumental variables strategy based on administrative delays in budgetary allocations...

We evaluate the impact of the Gambian hardship allowance, which provides a salary premium of 30-40% to primary school teachers in remote locations, on the distribution and characteristics of teachers across schools. A geographic discontinuity in the policy's implementation and the presence of...

Extreme weather induced by climate change can have major consequences for human health. In this study, I quantify the effect of tropical storm frequency and severity on mortality using objective meteorological data and the universe of vital statistics records from a large developing country,...

This paper studies two experiments of early childhood development programs in The Gambia: one increasing access to services, and another improving service quality. In the first experiment, new community-based early childhood development (ECD) centers were introduced to randomly chosen villages...

The types of workers recruited into teaching and their allocation across classrooms can greatly influence a country's stock of human capital. This paper considers how markets and non-market institutions determine the quantity, wages, skills, and spatial distribution of teachers in developing...

Researchers make hundreds of decisions about data collection, preparation, and analysis in their research. We use a many-analysts approach to measure the extent and impact of these decisions. Two published causal empirical results are replicated by seven replicators each. We find large...

Why is the proportion of women who study Economics so low? This study assesses whether students respond to messages about majoring in Economics, and whether this response varies by student gender. We conducted an experiment among more than 2,000 students enrolled in Economics Principles courses,...

We assess, via an experiment across 207 secondary schools, how a comprehensive teacher training program affects the delivery of a major entrepreneurship curriculum reform in Rwanda. The reform introduced interactive pedagogy and a focus on business skills in the country's required upper...
