The rapid growth of private participation in infrastructure (PPI) in developing countries during the 1990s was followed by a subsequent decline in investments and the re-negotiation and cancellation of some prominent projects. This has lead to controversy as to the impact and the future of PPI.This report attempts to explain the factors behind the growth and decline of PPI, its impact and the policy lessons that have been learnt from this experience. It concentrates on the experience with the private provision of infrastructure over the last 15 years.'Private Participation in Infrastructure in Developing Countries' assesses the impact that the private provision of infrastructure has had on service delivery. Finally, this book reviews the main policy lessons that can be drawn, and what governments need to do moving forward if they are to ensure that the supply of infrastructure services does not become an impediment to growth.
