9. Market for Crime Prevention Demand or Marginal Social Benefit: additional benefit from provision an extra unit of a public good Supply or Marginal Social Cost: additional cost of providing an extra unit of a public good

10. Optimal Level of Crime Prevention If we under-supply: MSB > MSC. It is beneficial to provide more crime prevention If we over-supply: MSC > MSB. It is beneficial to provide less crime prevention Optimal level of education: where D=S or MSB = MSC

13. Economic Cost-Benefit of Crime Costs –Loss of resources for crime prevention, apprehension, and judicial systems –Opportunity costs of resources used in crime prevention, apprehension, and judicial systems –Loss of income, both the criminal and victim –Expenditures on medical goods and services to treat the victim Benefits –Employment and income creation from prevention, apprehension, and judicial systems
