Some state and local governments are experimenting with new “pay-for-performance” contracts – sometimes called social impact bonds (SIBs) – to promote social innovation. In a SIB, the government contracts with an outside provider to achieve a measurable social goal (like reducing recidivism among juvenile offenders), private impact investors finance the program’s upfront costs, and the government promises a return to them if the program’s targets are achieved.
一些州和地方政府正在试验以“按表现付酬”合同——有时被称为社会影响债券（social impact bond，SIB）——促进社会创新。在SIB安排中，政府与外部供应商签订合同，后者需要实现可测量的社会目标（如降低青少年犯罪的再犯率），前期成本由私人影响力投资者提供融资，政府则承诺在计划目标实现后给予回报。
