Disease and Gender Gaps in Human Capital Investment: Evidence from Niger's 1986 Meningitis Epidemic

American Economic Review 2017 107(5), 530-535 open access
This paper examines whether disease burdens, especially prevalent in the tropics, contribute significantly to widening gender gaps in educational attainment. We estimate the impact of sudden exposure to the 1986 meningitis epidemic in Niger on girls' education relative to boys. Our results suggest that increases in meningitis cases during epidemic years significantly reduce years of education disproportionately for primary school-aged going girls in areas with higher meningitis exposure. There is no significant effect for boys in the same cohort and no effects of meningitis exposure for non-epidemic years. Our findings have broader implications for climate-induced disease effects on social inequality.

Federal Crop Insurance and the Disincentive to Adapt to Extreme Heat

American Economic Review 2015 105(5), 262-266 open access
Despite significant progress in average yields, the sensitivity of corn and soybean yields to extreme heat has remained relatively constant over time. We combine county-level corn and soybeans yields in the United States from 1989-2013 with the fraction of the planting area that is insured under the federal crop insurance program, which expanded greatly over this time period as premium subsidies increased from 20 percent to 60 percent. Insured corn and soybeans are significantly more sensitive to extreme heat that uninsured crops. Insured farmers do not have the incentive to engage in costly adaptation as insurance compensates them for potential losses.
