Traditional grants are not the only way to fund prevention. This lesson introduces Social Impact Bonds (SIBs) and “Pay for Success” models, where private investors fund interventions and governments repay them only if specific outcomes are achieved.

We explore the mechanics of this model and the rigorous understanding of “payable outcomes” required to make it work.

Practice quiz

Question 1
In a Social Impact Bond (SIB) or ‘Pay for Success’ arrangement, who provides the upfront capital that funds the intervention?
- The government agency that ultimately wants the outcome
- Private investors who are repaid only if outcomes are achieved
- The beneficiaries of the program through user fees
- A traditional foundation grant disbursed at kickoff
Question 2
Why is a rigorous understanding of ‘payable outcomes’ essential to making a Social Impact Bond work?
- Because investors need clearly measurable triggers that determine whether and how much they get repaid
- Because the IRS requires outcome definitions for tax-exempt bond status
- Because beneficiaries vote on which outcomes count
- Because outcomes determine the interest rate set by the Federal Reserve
Reflection 3
Explain in your own words how a Social Impact Bond shifts risk compared to a traditional prevention grant.
