This book grew out of a seminar on "Strengthening Public Investment and Managing Fiscal Risks from Public-Private Partnerships" that took place in Budapest during March 7-8, 2007. The seminar was jointly organized and sponsored by the International Monetary Fund, the Hungarian Ministry of Finance, and the International Center for Economic Growth, European Center (ICEG-EC). The idea for this book resulted from several factors: a significantly oversubscribed event that forced us to decline a large number of applicants owing to capacity constraints, the high quality of the contributions by the various presenters, and, finally, the excellent discussions that took place.
