This report, produced by Godeke Consulting and supported by the Rockefeller Foundation, explores the landscape of potential social impact bond (SIB) investors to determine how to build a sustainable market for SIBs that can leverage capital from a diverse set of investors to deliver better social outcomes to poor and vulnerable people. Researchers spoke with more than ninety investors and other stakeholders over an eight-month period of time, and have highlighted distinct investor insights that can inform the systems and structures needed to build a healthy market to finance SIBs.Delivering improved social and environmental conditions at scale will require more money than public dollars, philanthropy and civil society contributions can provide. In the current economy, as most major American cities and states are facing staggering budget deficits, taxpayers and politicians are not willing to risk their dollars for testing programs that are not a guaranteed success. In addition, publicly funded attempts to help poor or vulnerable populations are often remedial, ineffective and expensive. In the meantime, there are prevention-focused interventions with proven efficacy that are not being identified, taken up and scaled by government or that require more capital than governments can provide upfront. As a result, poor or vulnerable populations in the U.S. are not receiving the critical services they need.Access the full report here.
