Natural resources have driven both growth and conflict in modern Africa. We model the interaction of parties engaged in potential conflict over such resources. The likelihood of conflict depends on both the absolute and relative resource endowments of the parties. Resources fuel conflict by...

We show that psychological well-being in adulthood varies substantially with circumstance in early life.  Combining a time series of real producer prices of cocoa with a nationally representative household survey in Ghana, we find that a one standard deviation rise in the cocoa price in early...

We estimate the effects of higher quality healthcare usage on health, labor supply and schooling outcomes for sick individuals in Tanzania. Using exogenous variation in the cost of formal sector healthcare to predict treatment choice, we show that using better quality care improves health...

Self-selection into healthcare options on the basis of severity likely biases estimates of the effects of healthcare choice on health outcomes. Using an instrumental variables strategy which exploits exogenous variation in the cost of formal-sector care, we show that using such care to treat...

Models of the agricultural household have traditionally relied on assumptions regarding the complementarity or substitutability of family labor inputs. We show how data on time allocations, health shocks and corresponding treatment choices can be used to test these assumptions. Data from...

Smallholder agricultural commodity suppliers in developing countries are often vulnerable to global commodity price fluctuations. Using panel data on farmers from an area of Tanzania where most farmers grow coffee, this study finds that global coffee prices matter for household outcomes, through...

In 1924, The Morton Salt Company began nationwide distribution of iodine-fortified salt. Ac- cess to iodine, a key determinant of cognitive ability, rose sharply. We compare outcomes for cohorts exposed in utero with those of slightly older, unexposed cohorts, across states with high versus low...
