Public-Private Partnerships and Investment in Infrastructure

How can governments reap the potential benefits of public-private partnerships (PPPs) in the provision of infrastructure? Private sector involvement in the provision of public goods is long-standing, often relying on franchises or concessions. More recently, PPPs have risen in prominence, promising innovative solutions and a better allocation of inputs than traditional procurement with separate concessions. However PPPs are not without risks with the outcome depending on the identification of the most efficient bidder, the risk sharing between the public and private sector and the design of the contractual relationship. Furthermore, PPPs, particularly when they are used to circumvent budgetary constraints, present risks to government budgets by creating large contingent liabilities. Drawing on a discussion of the economics of PPPs in relation to infrastructure and questionnaire responses, synthetic indicators are used to assess how well-suited policy frameworks in the OECD are to benefit from PPPs. The results show marked heterogeneity across countries, suggesting there is scope to improve performance and gain expertise by considering other countries? experiences.
