Heterogeneous effects of violence on student achievement: Evidence from Colombia

Abstract

AbstractIn this paper, I study the causal relationship between violence and human capital accumulation. Due to a power vacuum left in conflict zones of Colombia after the 2016 peace agreement, large spikes in violence were reported in the municipalities of the country dominated by the rebel group FARC. I compare student test scores in municipalities that experienced the increase in violence to the ones that did not, before and after the national peace agreement. I find that a 10% increase in the homicide rate reduces average high school test scores by approximately 0.03 standard deviations. However, this impact is greater in the case of poor students who suffered a reduction of about 0.1 standard deviations per subject area, equivalent to 3.3 percentage points out of the final score. I also consider heterogeneity by gender finding a slightly larger negative impact on female students. This disparate effect on women and on the poorest students adds new evidence to the literature on the effects of armed conflict on learning outcomes.
