Notes: Dependent variable is the average rank of maize yields calculated over the four seasons (short rain 14 to long rain 16). Controls include education, literacy, gender, age and age squared of the farmer, land and cattle ownership, size and quality of the house, household size, whether the farmer is the household head, household head’s gender, village fixed effects, and enumerator-assignment fixed effects. IRT is item response theory. LOC is locus of control. NC is noncognitive. Standard errors clustered at village level in parentheses. Significance: *p < 0.1, **p < 0.05, ***p < 0.01.
