Focusing Law Enforcement When Offenders Can Choose Location

This paper explores the advantages of focusing law enforcement on some locations when offenders can choose locations. The substitutability of different crimes from the offender's perspective is established as the key variable determining whether asymmetric enforcement is socially desirable. When it is easy for offenders to substitute crimes, focused law enforcement can be preferable only when the act imposes more harm in one location than in another (e.g., speeding in a residential or industrial area).
