This book provides a balanced presentation of international trends in infrastructure regulation and financing. Based on recent developments in microeconomic theory, it comprehensively discusses the role of the state and the private sector in infrastructure provision. As well as a thorough overview of the relevant theoretical issues, the authors carefully examine national experiences of private participation in infrastructure. In particular, they explore sectoral restructuring in the electricity, telecommunications, water and transport sectors. The book includes case studies from both Argentina and the UK, and places a particular focus on Germany which, for a developed country, is a peculiar latecomer in terms of infrastructure sector reform. Well argued and rich in new insights, this book offers a meticulous and informative analysis of current trends in infrastructure privatization and deregulation. Among the authors are well-known specialists as well as younger researchers who provide a fresh perspective on the issue. The book will be of interest and relevance to researchers, academics, policymakers and international organizations interested in regulation and the modernization of infrastructure both in developed and developing countries.
