Prison Rehabilitation Programs: Efficiency and Targeting

Increasing evidence suggests that incarceration can improve inmates' social reintegration under certain circumstances. Yet, the mechanisms through which incarceration may lead to successful rehabilitation remain largely unknown. This paper finds that participation in social rehabilitation programs can significantly reduce recidivism only when inmates are evaluated by an assessment tool which allows to identify their criminogenic needs. This suggests that targeting criminogenic needs is crucial for successful rehabilitation. We also find that inmates with a high risk score or who exhibit procriminal attitudes benefit little from participation. To control for selection, we instrument participation with program availability at the time and place of incarceration. We also use a coefficient stability approach to test for omitted variable biases. Both approaches yield similar results.
