Ganong on Rehabilitation, Incapacitation, and Aging

Peter Ganong has posted Rehabilitation, Incapacitation, and Aging: Evidence from Georgia on SSRN.  Here is the abstract: 

In April 1993, Georgia instituted new parole guidelines that led to longer prison terms for parole-eligible offenders. This paper shows that an extra year of prison reduces the three-year recidivism rate by 6 percentage points (14 percent); and the benefits of preventing this crime are likely outweighed by the costs of this additional incarceration. 

I develop a new econometric framework to jointly estimate the effects of rehabilitation, incapacitation, and aging in reducing crime. Estimates of incapacitation effects using existing methodologies are biased upward by at least a factor of two because they focus on a short time horizon.

When I directed the evaluation unit for the Oklahoma Department of Corrections, we discovered that the effect of sentence length and time served on later recidivism varied by the offenders' risk/need assessment scores. Low and moderate risk/need offenders did worse with longer sentences and times served while high risk/need offenders had the patterns described in this paper, which would not be surprising given the parole changes. Caution should be applied in asserting that a given increase in time served results in less recidivism for ALL offenders, which is how this research will be used. It wasn't true in Oklahoma and I doubt it's true in Georgia.
