Unemployment and gang crime: Can prosperity backfire?

In this paper, we study how unemployment affects gang crime. We examine a model of criminal gangs and suggest that a substitution effect between petty crime and severe crime is at work. In the model, non-monetary valuation of gang membership is private knowledge. Thus, the leaders face a trade-off between less crime per member in large gangs and more crime per member in small gangs. A decrease in unemployment may result in a switch from a large gang that requires petty crime to a small gang that requires severe crime.
