Social impact bonds are a promising new approach to government financing of social service programs. By combining performance-based payments and market discipline, pay-for-success contracts using social impact bonds have the potential to improve results, overcome barriers to social innovation, and encourage investments in cost-saving preventive services.
Established with support from the Rockefeller Foundation, the Harvard Kennedy School’s social impact bond technical assistance lab (SIB Lab) conducts research on how governments can foster social innovation and improve the results they obtain with their social spending. An important part of our research model involves providing pro bono technical assistance to state and local governments implementing pay-for-success contracts using social impact bonds. Through this hands-on involvement, we gain insights into the barriers that governments face and the solutions that can overcome the barriers. By engaging current students and recent graduates in this effort, we are able to provide experiential learning as well. Over the past year, the SIB lab has helped Massachusetts and New York become the first US state governments to develop pay-for-success contracts using social impact bonds.
