Payment by Results

Payment by Results is a financial mechanism that ties remuneration to measurable outcomes, linking compensation to performance indicators, targets, or deliverables. It is used across sectors to align incentives among funders, providers, and beneficiaries, and has been adopted by a variety of institutions, projects, and governments to drive efficiency, accountability, and innovation. Practitioners, evaluators, and policymakers debate its design, measurement, and impacts amid diverse political, organizational, and fiscal contexts.

Overview

Payment by Results schemes connect payments to predefined results such as outputs, outcomes, or impact, and often involve contracts, grants, or procurement arrangements administered by entities like the World Bank, European Commission, United Nations, United States Agency for International Development, and national ministries. Variants include performance-based contracting used by National Health Service (England), results-based financing piloted by Gavi, the Vaccine Alliance and Global Fund to Fight AIDS, Tuberculosis and Malaria, and social impact bonds developed with partners such as Goldman Sachs, Social Finance UK, and municipal governments like New York City and London. Implementation brings together actors such as multilateral agencies, bilateral donors, philanthropic organizations including the Bill & Melinda Gates Foundation and Rockefeller Foundation, as well as research institutions like RAND Corporation, Brookings Institution, and International Monetary Fund.

Historical development

Origins trace to 19th-century administrative reforms in the United Kingdom and fiscal practices of the Ottoman Empire and British Empire, evolving through public administration reforms associated with figures such as Frederick Winslow Taylor and management movements tied to Herbert A. Simon. Twentieth-century developments involved procurement innovations in United States Department of Defense contracting and performance budgeting advocated by administrations like Franklin D. Roosevelt’s New Deal and metrics pushed during the Reagan administration. The 1990s and 2000s saw diffusion through initiatives from Organisation for Economic Co-operation and Development and neoliberal policy networks involving think tanks like American Enterprise Institute and Cato Institute, with notable applications by Chile’s social policies and Rwanda’s health sector reforms. The recent decade features impact investing trends shaped by forums such as the World Economic Forum and legal instruments influenced by the European Court of Auditors.

Models and mechanisms

Common models include per-unit payments used by agencies such as Centers for Medicare & Medicaid Services; pay-for-performance schemes exemplified by NHS England’s Quality and Outcomes Framework; conditional cash transfers modeled after Bolsa Família in Brazil and Prospera in Mexico; and advance market commitments promoted by Gavi, the Vaccine Alliance. Contractual mechanisms range from fee-for-service procurement in United States federal contracting to outcome-payments in development projects financed by World Bank’s Development Impact Bonds and social impact bonds arranged with investors like Barclays and UBS. Measurement mechanisms draw on evaluation designs from researchers at Harvard University, University of Chicago, London School of Economics, and Massachusetts Institute of Technology, employing randomized controlled trials used in studies by Abhijit Banerjee and Esther Duflo and quasi-experimental methods popularized by Angus Deaton.

Applications by sector

In health, pay-for-performance has been trialed in programs linked to World Health Organization recommendations and in national systems such as NHS England and Rwanda Ministry of Health, affecting providers like Mayo Clinic and Kaiser Permanente. In education, performance contracts have been used in districts including Chicago Public Schools and charter networks such as KIPP and funders like Gates Foundation have supported outcome-based grants. In international development, results-based financing has been deployed in projects funded by Foreign, Commonwealth & Development Office and administered alongside United Nations Development Programme initiatives; in social services, programs in New York City and Melbourne have used social impact bonds. Infrastructure and environmental projects involve mechanisms similar to payment-by-results in renewable procurement auctions influenced by International Renewable Energy Agency and carbon finance arrangements under frameworks linked to United Nations Framework Convention on Climate Change.

Economic and empirical evidence

Empirical literature includes evaluations published by Journal of Health Economics, American Economic Review, and Quarterly Journal of Economics examining effects on quality, cost, and equity. Meta-analyses from institutions like Cochrane Collaboration and working papers from National Bureau of Economic Research assess heterogenous impacts found in studies of Brazil’s Bolsa Família, Rwanda’s health payments, and India’s conditional cash transfers. Theoretical work builds on principal-agent models from Michael Jensen and William Meckling and contract theory by Oliver Hart and Bengt Holmström, while behavioral critiques reference findings by Daniel Kahneman and Richard Thaler.

Implementation challenges and criticisms

Critics include researchers and NGOs such as Amnesty International and Oxfam raising concerns about perverse incentives, gaming, and measurement distortions observed in audits by bodies like United Kingdom National Audit Office and studies by Transparency International. Other challenges documented by scholars at Princeton University and Yale University involve attribution problems, transaction costs highlighted by OECD reports, and equity implications examined in analyses by UNICEF and World Health Organization. Legal and ethical critiques cite cases adjudicated in national courts including Supreme Court of the United States and European Court of Human Rights where contractual obligations conflicted with statutory duties.

Policy and regulatory considerations

Policymakers in institutions such as European Commission, United States Congress, and national parliaments must design safeguards including robust monitoring by agencies like General Accounting Office and independent evaluation by organizations like Independent Evaluation Group at the World Bank. Regulatory frameworks intersect with procurement law exemplified by the WTO Government Procurement Agreement, data protection regimes such as General Data Protection Regulation enforcement in European Union, and public finance rules overseen by International Monetary Fund advice. Best practice guidance from World Bank, OECD, and United Nations emphasizes transparency, stakeholder engagement involving civil society groups like Human Rights Watch, and alignment with strategic plans of ministries such as Ministry of Finance (United Kingdom) and U.S. Department of Health and Human Services.
