We study the origins of adult mental health using early life income fluctuations.  Combining a time series of real producer prices of cocoa with a nationally representative household survey in Ghana, we show that a one standard deviation rise in the cocoa price in early life decreases the...

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...

Self-selection into healthcare options biases estimates of the effects of healthcare on health outcomes. We exploit exogenous variation in the cost of formal-sector care to show that the use of such care improves short-term health outcomes for acutely ill children in Tanzania. Better...

In 1924, The Morton Salt Company began nationwide distribution of iodine-fortified salt. Access 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...

We study the effects of accessing better healthcare on the schooling and labor supply decisions of sick children in Tanzania. Using variation in the cost of formal-sector healthcare to predict treatment choice, we show that accessing better healthcare decreases length of illness and changes...

We test whether living through conflict in childhood changes political beliefs and engagement. We combine data on the location and intensity of conflicts since 1945 with nationally representative data on political attitudes and behaviors from 17 sub-Saharan African countries. Exposure from ages...

A key prediction of dynamic labor demand models is that firing restrictions attenuate firms' employment responses to economic fluctuations. We provide the first direct test of this prediction using data from India. We exploit the fact that rainfall fluctuations, through their effects on...

We test whether early-life war exposure influences later-life political engagement in Africa.  We combine data on the location and intensity of conflicts since 1954 with nationally representative data on political attitudes and behaviors from 17 sub-Saharan African countries.  Exposure from...

I show that malaria misdiagnosis, common in resource-poor settings, decreases the expected effectiveness of an important new therapy--since only a fraction of treated individuals have malaria--and reduces the rate of learning via increased noise. Using pilot program data from Tanzania, I exploit...
