Imprisonment and crime

Since 1972, the rate of incarceration in U.S. state and federal prisons has increased every year without exception from a rate of 96 prisoners per 100,000 population in 1972 to 504 prisoners per 100,000 in 2008 (BJS, 2008).1 Counting those housed in jails, the nation’s total incarceration rate has surpassed 750 per 100,000 (Liptak, 2008). Accompanying the 40-year increase in imprisonment has been a companion growth in corrections budgets from $9 billion in 1982 to $69 billion in 2006, which is a 660% increase (BJS, 2008). Much research has been done on the effect of this increase in incarceration on crime rates as well as on the social and economic costs of the ensuing fivefold increase in the nation’s imprisonment rate. The point of departure for this article is the recognition that sanction policies that reduce both crime and punishment have the desirable feature of avoiding not only the costs of crime but also the costs of administering punishment. As a theoretical matter, this observation is certainly not new and was recognized at least as long ago as Becker (1968). Of course, the policy question is whether, relative to the status quo, alternative policies exist that can achieve these simultaneous effects. In this article, we argue that it is a realistic possibility that crime, prison costs, and imprisonment numbers can be
