Growing up inside the invisible frontier: the effect of gang’s territorial control on youth’s human capital accumulation (JMP).

How does the enforcement of gang’s territorial borders affects children’s and youth’s human capital accumulation? I explore this question in Medellín, Colombia. To be able to observe binding gang borders, I focus on a city-wide gang turf that happened during 2009-2012. I map the borders of one of the competing factions and perform a spatial regression discontinuity using geo-located individual level data on educational enrollment. I find that the probability of dropping out of high school is 7 p.p higher for teenage male students living inside the gang border than for students living only 150m outside of it. This discontinuity did not exist before the gang border become binding for non-gang members.
