We develop a quantitative theory of mortality trends and population dynamics. We emphasize diseases as causes of death and individuals' decisions to reduce their mortality by adopting, at some cost, a modern health-related technology. Adoption confers a dynamic externality: Adoption becomes...

We exploit a spatial discontinuity in the coverage of an agricultural extension program in Uganda to causally identify its effects on malaria. We find that eligibility for the program reduced the incidence of malaria by 8.8 percentage points, with children and pregnant women experiencing most of...

Malaria still claims a heavy human and economic toll, specifically in sub-Saharan Africa. Even though the causality between malaria and poverty is presumably bi-directional, malaria plays a role in the economic difficulties of the region. This article provides an analysis of the economic...

Using data from a randomised experiment in Kenya, we estimate the causal effect of social networks on technology adoption. In this experiment, farmers were invited to information sessions about the use of Tissue Culture Banana (TCB), an in vitro banana cultivation technology. We find that an...
