Measuring Criminal Spillovers: Evidence from Three Strikes.

California's Attorney General was pleased to announce that "An unintended but positive consequence of 'Three-Strikes' has been the impact on parolees leaving the state¿.The growth in the number of parolees leaving California is staggering." Law enforcement officers in other states were presumably less pleased. A displaced criminal is a benefit to California but a cost to other states. If such criminal spillovers are important, law enforcement will over-invest in policies that encourage displacement. We test whether California's three-strikes law led to significant criminal spillovers. [ABSTRACT FROM AUTHOR]
