RAND Europe was commissioned by the UK Ministry of Justice to evaluate the world's first Social Impact Bond (SIB), an innovative payment-by-results mechanism to fund public services. Implemented in a prison in Peterborough in eastern England, this first SIB aimed to reduce reoffending by prisoners who have served short custodial sentences. The third and final report from RAND's evaluation provides evidence and key lessons on the operation of this funding model, informing the possible development and roll-out of SIBs in other policy areas and in other parts of the UK.
