Abstract: | Governments across the world have introduced a variety of instruments to enhance private investors’ appetites for public–private partnership (PPP) projects. The use of such instruments has become a core component of development and growth policies, for example by the EU as part of the Junker Plan. This paper provides a comprehensive categorization of these instruments, the risks they target and their effects, at both the project and system level, to support policy-makers to design the most appropriate instruments to attract private capital into infrastructure development. |
