The next three questiоns rely оn the fоllowing аssumptions: Recаll thаt the economic goal of criminal law is to minimize the sum of: (1) the social cost of the crimes that are committed (the SCCC), and (2) the cost of catching, trying, and punishing the offenders who are caught (the CTPO). Suppose that a crime has a social cost of $10,000 each time it is committed. Every time an offender is caught, he or she is tried, convicted, and imprisoned. The cost of catching, trying, and punishing each offender who gets caught is $100,000. A city is considering hiring additional police dedicated to detecting this crime. The change would increase the fraction of offenders who get caught from 15% to 20%. Suppose this increase in detection would result in a decrease in the number of crimes committed from 1,000 a year to 800 a year. What effect would hiring the additional police have on the social cost of crimes committed (the SCCC)?
