This paper analyses the impact of the introduction of an Earning or Learning reform on youth crime in Queensland, Australia. The 2006 reform increased learning and reduced earning as school participation rose post-reform, while teen employment fell. Empirical analysis of detailed administrative data reveals that criminal offending fell significantly after enactment of the reform. For males, violent, property and drug crime all declined, while the main effect for females was a significant fall in property crime. The property and drug crime falls are underpinned by a significant incapacitation effect, with some evidence of a persistent crime reduction for young men and women at later ages. Crime reduction is concentrated in significant falls in the likelihood of ever offending by marginal individuals, rather than lower criminality among recalcitrant persistent offenders.
