Income shocks and education: How coffee price booms affect schooling in Rwanda (currently under review at the Journal of Development Economics)

This  paper provides novel evidence on the short and long term effects of coffee price booms on schooling outcomes in Rwanda. Exploiting the exogeneity of international coffee prices and spatial variation in coffee cultivation intensity across Rwanda, I show that children are more likely to attend school when coffee prices are high and complete more years of schooling by the age of 18. I provide evidence that income effects are the main mechanism and dominate increased opportunity costs of schooling. However, educational gains are concentrated among households near privately operated washing stations, rather than households near cooperatives, suggesting that privately managed washing stations transmit income gains differently to local households than cooperatives. For privately operated stations, smaller station sizes, rather than differences in coffee quality, explains the observed effects. Overall, my findings highlight important heterogeneity in how commodity booms translate into educational gains in exporting countries.

The Human Capital Costs of Violent Teachers (R&R at the Economics of Education Review)

This paper provides evidence on the effect of violent teachers on human capital formation. I combine panel data from multiple cohorts of primary students in rural Malawi with detailed information on their teachers’ violent behavior during class, including physical, emotional and sexual violence. To tackle the potential endogeneity of teacher violence, I apply a difference-in-differences strategy with staggered treatment and estimate a value-added model that includes teacher fixed effects and lagged student's test scores. My results suggest that violent teachers reduce successful grade progression by 30 percentage points and math scores by 15 percentage points over an academic year. Early secondary students show the highest effects. I do not find any significant effects on English and Chichewa test scores.
