The OECD Principles for Public Governance of Public-Private Partnerships provide concrete guidance to policy makers on how to make sure that Public-Private Partnerships (PPP) represent value for money for the public sector. In concrete terms, the Principles will help ensure new projects add value and stop bad projects going forward. They provide guidance on when a PPP is relevant – e.g. not for projects with rapidly changing technology such as IT, but possibly for well known generic technology such as roads. They focus on how you need to get public sector areas aligned for this to work: institutional design, regulation, competition, budgetary transparency, fiscal policy and integrity at all levels of government.
