This paper examines the competitive effects of reorganizing a network industry's vertical structure. In this industry, an upstream monopolist operates a network used as an input to produce horizontally differentiated final products that are imperfect substitutes. Three potential pitfalls of restructuring integrated network industries are analyzed: (i) double marginalization, (ii) underinvestment, and (iii) vertical foreclosure. The paper studies the net effect of restructuring on retail prices and cost-reducing investment and discusses policy implications.

This paper examines the effects of introducing competition into monopolized network industries on prices and infrastructure quality. Analyzing a model with reduced-form demand, we first show that deregulating an integrated monopoly cannot simultaneously decrease the retail price and increase infrastructure quality. Second, we derive conditions under which reducing both retail price and infrastructure quality relative to the integrated monopoly outcome increases welfare. Third, we argue that restructuring and setting very low access charges may yield welfare losses, as infrastructure investment is undermined. We provide an extensive analysis of the linear demand model and discuss policy implications. -- infrastructure quality ; deregulation ; investment incentives ; access charges ; regulation

New industries are emerging; others are disrupted; old barriers are crumbling, while new ones are rising. This book seeks to better understand the challenges facing industries, networks, businesses and management during periods of industry structuring and restructuring. Comprising a series of contributions from experts in the field, the book addresses key questions about the opportunities and threats posed by these times of turmoil, including: How do existing industries sustain their competitiveness in such difficult times? How do networks stave off threats from new technologies? How do emerging and incumbent companies survive when growth is not an option? And how should companies be governed during periods of industry structuring and restructuring? In answering these questions, the contributors provide an overview of the strategies that industries, networks, businesses and managers are currently deploying in order to adapt to chaotic conditions and to enhance business profitability. Their responses make a distinctive contribution to scholarly thought and management practice.

'To learn about how economic and institutional forces have shaped the network industries and policies towards them, read the first part of the book. To discover their impacts on particular industries, read the second part. And to find out what has happened in particular countries, read the third part. I think anyone interested in network industries should read all of it! The book's structure allows for many interesting comparisons across countries and sectors.' Richard Green, University of Birmingham, UK 'This is a very useful and comprehensive guide to reforms in network industries in communications, energy, transport and water. It is organized by generic topic, sector and region. Its authors are acknowledged experts. I am confident that this Handbook will be a widely read and valuable resource for many years.' Martin Cave, London School of Economics, UK 'Quite an accomplishment, this Handbook provides by far the most comprehensive overview of the role of the private sector and competition in infrastructure industries, with thoughtful surveys of each of the major infrastructure sectors and of the key regions and countries.' José Gómez-Ibáñez, Harvard University, US In recent decades, all infrastructures have undergone significant restructuring. This worldwide phenomenon is often labelled 'liberalization' and although expectations were high with respect to lower prices, greater efficiency and innovation, the expected gains have not always been fully realized. This extensive, state-of-the-art Handbook provides a comprehensive overview of the various experiences of liberalization across different sectors, regions and disciplines. The multidisciplinary approach focuses on the economic, political and institutional aspects of liberalization as well as, to a lesser extent, on technological issues. As such, it constitutes a unique contribution, as this broad overview is often lost in the sector specific, country-focused and purely disciplinary approaches prevalent in the current literature. Sectors explored include telecoms, the Internet, energy and transport, whilst the truly global perspective incorporates unique case studies from an array of developed and developing countries including the US, China, India and the EU. The International Handbook of Network Industries will become the definitive volume for academics researchers and students of economics, political science and law interested in infrastructure regulation. It will also prove a valuable guide to practitioners and policy-makers involved in liberalization and competition.

Restructuring brings market incentives into formerly monopolized network industries and raises a host of questions about whether the carrot of profit seeking can be disciplined by the stick of competition. In the telephone industry access pricing is an issue, and major problems are illustrated. In the electricity industry other problems are described and possible solutions are briefly sketched.
