Pay for success contract

What Is a Pay for Success Contract?

A pay for success contract (PFS) is an innovative funding model within the realm of social finance where payments are made only if predefined social outcomes are achieved. Unlike traditional contracts that pay for services rendered, regardless of their effectiveness, a pay for success contract links payment directly to measurable results¹⁵, ¹⁶. This contractual arrangement typically involves a government entity as the "outcome payer," private investors who provide upfront capital to fund social interventions, and service providers who deliver the actual programs¹⁴. The goal of a pay for success contract is to incentivize efficient and effective delivery of social programs by shifting financial risk transfer from the public sector to investors¹³.

History and Origin

The concept of pay for success contracts, often known interchangeably as social impact bonds (SIBs), emerged from the United Kingdom in the late 2000s. The world's first social impact bond was launched by Social Finance UK in 2010. This pioneering initiative aimed to reduce recidivism among short-sentenced prisoners leaving HMP Peterborough¹¹, ¹². Investors provided the upfront funding for rehabilitation services, and the UK Ministry of Justice agreed to repay them, with a return, only if reoffending rates were reduced by a specified percentage. This model was designed to tackle persistent social problems by encouraging innovation and accountability in service delivery. Following its initial success and growing interest, the pay for success framework began to expand globally, with countries like the United States adopting similar approaches in subsequent years¹⁰.

Interpreting the Pay for Success Contract

Interpreting a pay for success contract primarily involves evaluating whether the agreed-upon outcomes have been achieved and to what extent. Success is not measured by the delivery of services themselves, but by the tangible, measurable improvements in the target population⁹. For example, in a contract designed to reduce homelessness, success would be measured by the number of individuals securing stable housing for a specified period, rather than merely the number of shelter nights provided.

A critical component is the role of an independent evaluator, who rigorously assesses whether the specified performance metrics have been met. This ensures objectivity and provides credible data on the program's effectiveness. The interpretation also extends to understanding the financial implications for all parties: for the government, it signifies whether they are paying for proven results and potentially realizing long-term savings; for investors, it determines their return on investment; and for service providers, it validates the efficacy of their interventions and may unlock future funding opportunities.

Hypothetical Example

Consider a hypothetical pay for success contract aimed at improving kindergarten readiness for at-risk children in a specific community.

Problem Identification: The local government agencies identify that a significant percentage of children from low-income families enter kindergarten without basic literacy and numeracy skills, leading to higher future special education costs.
Intervention & Funding: A non-profit organization, specializing in early childhood development, proposes an evidence-based home-visiting program. Private investors provide $5 million in upfront capital to the non-profit to run this program for 300 children over three years.
Outcome Definition: The contract stipulates that the government will pay the investors if at least 70% of participating children demonstrate readiness for kindergarten, as measured by a standardized assessment administered by an independent evaluator. The payment structure includes a principal repayment plus a bonus for exceeding the 70% threshold, capped at a certain amount.
Implementation & Evaluation: The non-profit implements the program, providing services. After three years, the independent evaluator conducts the assessments.
Outcome Payment: If 75% of the children meet the kindergarten readiness benchmark, the government pays the investors their initial $5 million plus an agreed-upon return, reflecting the successful outcome and the avoided future special education costs. If the target is not met, investors receive less or none of their capital back, demonstrating the risk transfer inherent in the pay for success contract model.

Practical Applications

Pay for success contracts are increasingly applied across various social sectors where measurable outcomes and long-term societal benefits can be identified. These include:

Criminal Justice: Reducing recidivism rates for former prisoners through employment training and rehabilitative services. The first social impact bond in the UK focused on this area at HMP Peterborough⁸.
Early Childhood Development: Improving school readiness, preventing child abuse and neglect, and reducing the need for special education services⁷.
Homelessness: Providing supportive housing and integrated services to chronically homeless individuals to reduce emergency service utilization and improve stability.
Public Health: Addressing issues such as diabetes prevention, maternal and child health, and substance abuse treatment⁶.
Workforce Development: Enhancing employment outcomes for hard-to-employ populations, which can lead to reduced reliance on public assistance⁵.

These applications highlight the shift from paying for services to paying for results, fostering greater accountability and innovation in the delivery of public services. The Urban Institute provides further insights into various Pay for Success projects launched across the United States in areas like early childhood education and chronic homelessness.⁴

Limitations and Criticisms

Despite their potential, pay for success contracts face several limitations and criticisms. One significant concern is the high transaction costs associated with their development and implementation³. Structuring these complex financial instruments requires extensive legal, financial, and evaluation expertise, which can be costly and time-consuming, potentially making them less suitable for smaller projects.

Another critique revolves around the difficulty of accurately measuring and attributing complex social outcomes. For some interventions, establishing clear cause-and-effect relationships and isolating the program's impact from other factors can be challenging. There are also concerns about the potential for "cherry-picking," where service providers might select easier-to-serve populations to ensure the achievement of targets, inadvertently excluding those most in need². Additionally, critics point to the risk that a focus on quantifiable, short-term performance metrics could lead to a neglect of broader, more profound, but harder-to-measure, long-term impacts. Cases of overstated results, such as initial findings from an early education program in Utah, have also drawn scrutiny, raising questions about data integrity and reporting.

Pay for Success Contract vs. Social Impact Bond

The terms "pay for success contract" and "social impact bond" are often used interchangeably, but there is a subtle distinction. A pay for success contract (PFS) is the broader contractual framework where payment from a government or outcome funder is contingent on achieving specific, measurable social outcomes. It is an overarching concept for outcomes-based funding.

A social impact bond (SIB) is a specific type of pay for success contract that introduces an additional layer: private investors provide the upfront capital to fund the intervention. In an SIB, if the program achieves its targets, the government repays these investors their principal plus a return, typically from the savings generated or other designated funds. If the outcomes are not met, the investors bear the financial loss. This structure facilitates impact investing by connecting financial returns to social improvements. While all social impact bonds are pay for success contracts, not all pay for success contracts are structured as social impact bonds; some may involve direct contracts with service providers without an intermediary investor¹.

FAQs

Q: Who participates in a pay for success contract?
A: Typically, three main parties are involved: an "outcome payer" (often a government agencies or philanthropy), service providers who deliver the intervention, and private investors (in the case of a social impact bond) who provide upfront funding. An independent evaluator also plays a crucial role in assessing outcomes.

Q: What are the main benefits of a pay for success contract?
A: Benefits include shifting financial risk from the public sector, encouraging innovation in social service delivery, promoting evidence-based policies, and ensuring public funds are spent on programs that demonstrate measurable results. It also provides an opportunity for impact investing.

Q: Are pay for success contracts guaranteed to save money?
A: No. While a core aim is to achieve cost savings for the government through effective prevention or intervention, there is no guarantee. Payments are made only if specified outcomes are met, which transfers the financial risk to investors in a social impact bond structure. If the program fails to achieve results, the government pays less or nothing, but the intended societal improvement and potential savings may not materialize.
