Abstract
Dual labor market theory, developed as an explanation of underemployment and poverty within the economy, may also be applied to the illicit economy of crime. Criminal careers are differentiated into a primary sector, with occupational stability, low failure rate, and high chances of advancement; and a secondary sector, with instability, high failure rate, and lack of "market" control. The attraction of criminal careers, the likelihood of incarceration, and the effects of law enforcement are best understood in these contexts
