Network industries comprise a large sector of the US economy. This text shows that public policy concerns are not accidental, because such industries often embody two major and widely recognized forms of potential market failure: significant economies of scale, and externalities.

Although the airline, railroad, telecommunications, and electric power industries are at very different stages in adjusting to regulatory reform, each industry faces the same critical public policy question: Are policymakers taking appropriate steps to stimulate competition or are they turning back the clock by slowing the process of deregulation? This volume addresses that issue and identifies the next steps that policymakers should take to enhance public welfare in the provision of these services. Each chapter identifies the central policy issues that have arisen in each industry as it undergoes transformation to a deregulated environment. The authors reveal the flaws in the residual regulations and make the case for faster and more comprehensive deregulation. A concluding chapter identifies how interest groups continue to exert influence on regulatory agencies and on Congress, potentially undermining deregulation. The papers included here were initially presented in December 1999 at a conference sponsored and organized by the AEI–Brookings Joint Center for Regulatory Studies.

For close to 100 years, America's surface freight industries, primarily rail and trucking, operated under the protective wing of the U.S. government. In 1980 Congress, finding vast inefficiencies in the two industries, substantially deregulated both, opening them at last to market competition. Deregulation has brought with it many changes—for firms within the industries, for their labor force, and for shippers and their customers. Clifford Winston, Thomas M. Corsi, Curtis M. Grimm, and Carol A Evans provide a comprehensive evaluation of the effect of the deregulation legislation on the rail and trucking industries. According to the authors, deregulation has made substantial progress in solving the two most vexing problems of the surface freight transportation industry—excessive rates in the trucking industry and insufficient returns on investment in the rail industry. Competition and efficiency have returned to both industries, and although the labor force in each has suffered wage and job losses, shippers and their customers have gained roughly $20 billion a year in benefits. The authors recommend policies that would continue to promote competition and the efficient use of highway and railway infrastructure.

Have you ever wondered how your telephone company or Internet service provider can give you access to almost all people in the world, or how electricity suppliers can compete with each other if there is only one electric supply line passing through your street? This Element deals with the economics and public regulation of such network industries. It puts particular emphasis on the specific economic concepts used for analyzing them and on the regulatory reform movement and the compatibility of regulation and competition. Worldwide most of these industries have changed dramatically in recent years, telecommunications in particular. Network industries mostly exhibit economies of scale in production and similar economies in consumption. Both of these properties cause market power problems that often require industry-specific regulation. However, due to technological and market changes network policies have moved on from end-user regulation to wholesale regulation and in some cases to deregulation.

'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.

The unique challenges associated with understanding network industries requires insights from a range of disciplinary perspectives, namely economics, engineering, law, and political science. This book analyzes the de- and re-regulation of the network industries and the regulatory challenges these industries will face in the future. Network industries are characterised by economics that entail limiting effects on competition and market creation, and the book highlights the drivers behind their liberalization as well as the inherent need for regulation as liberalization unfolds. By way of an historical approach, the author offers insights into the distinctive approaches between Europe and North America in the past whilst also presenting the pervasive role digitalization increasingly comes to play. A concise overview of the state of thinking about the network industries, this book will be vital reading for researchers, advanced students and practitioners.

This paper discusses how antitrust law and regulatory rules should be applied to network industries. In assessing the application of antitrust in network industries, we analyze a number of relevant features of network industries and the way in which antitrust law and regulatory rules can affect them. These relevant features include (among others) network effects, market structure, market share and profits inequality, choice of technical standards, relationship between the number of active firms and social benefits, existence of market power, leveraging of market power in complementary markets, and innovation races. We find that there are often significant differences on the effects of application of antitrust law in network and non-network industries.
