We use a unique data set detailing the financial activities of a drug-selli
ng street gang to analyze gang economics. On average, earnings in the gang
are somewhat above the legitimate labor market alternative. The enormous ri
sks of drug selling, however, more than offset this small wage premium. Com
pensation within the gang is highly skewed, and the prospect of future rich
es, not current wages, is the primary economic motivation. The gang engages
in repeated gang wars and sometimes prices below marginal cost. Our result
s suggest that economic factors alone are unlikely to adequately explain in
dividual participation in the gang or gang behavior.
