We combine a natural experiment with administrative data from England and Wales to assess a key community correctional policy: post-release supervision. We find that supervision reduces re-offending in the first four weeks after prison release by 15%, in part due to the incapacitation of prolific offenders who are recalled to prison for violations of their probation terms. Supervision also causes a 5.5% reduction in re-offending three years after release. This effect persistence, which is even stronger for first-time prisoners, suggests that post-release supervision is a cost-efficient way to induces genuine behavioural change.
