Human capital in the inner city

Black males in the United States are exposed to tremendous violence at young ages: In the NLSY97 26 percent report seeing someone shot by age 12, and 43 percent by age 18. This paper studies how this exposure to violence and its associated social isolation affect education and labor market outcomes. I use Elijah Anderson?s ethnographic research on the ?code of the street? to guide the specification of a model of human capital accumulation that includes street capital, the skills and knowledge useful for providing personal security in neighborhoods where it is not provided by state institutions. The model is estimated assuming either selection on observables or dynamic selection with permanent unobserved heterogeneity. Counterfactuals from these estimated models indicate that exposure to violence has large effects, decreasing the high school graduation rate between 6.1 and 10.5 percentage points (20 and 35 percent of the high school dropout rate) and hours worked between 3.0 and 4.0 hours per week (0.15 and 0.19 s).
