Between 1967 and 1974, a bilateral treaty increased circular labor migration from Malawi to South Africa by 200%, bringing over 53 million USD in earnings into origin communities. A deadly migrant worker plane crash in 1974 ended these flows and led to migrant repatriation. We study how this...

We provide new evidence of one channel through which circular labor migration has long run effects on origin communities: by raising completed human capital of the next generation. We estimate the net effects of migration from Malawi to South African mines using newly digitized Census and...

Drought is Africa's most prevalent natural disaster and is becoming an increasingly common source of income shocks around the world. This paper presents new evidence from Africa that droughts are an important component of long run variation in health human capital. I use Census data to estimate...

Drought is Africa's primary natural disaster and a pervasive source of income risk for poor households. This paper documents the long-run health effects of early life exposure to drought and investigates an important source of heterogeneity in these effects. Combining birth cohort variation in...

The direct benefits of infrastructure in developing countries can be large, but if new infrastructure induces in-migration, congestion of other local publicly provided goods may offset the direct benefits. Using the example of rural household electrification in South Africa, we demonstrate the...

Cellular technologies have become increasingly important in the developing world; infrastructure for mobile networks has expanded dramatically over the past two decades giving access to remote areas without previous phone service. Despite this expansion, relatively little is known about the...

The spread of the HIV/AIDS epidemic is still fueled by ignorance in many parts of the world. Filling in knowledge gaps, particularly between men and women, is considered key to preventing future infections and to reducing female vulnerabilities to the disease. However, such knowledge is arguably...
