Telecommunications have become the information highways of an increasingly service-based economy. With the acceleration of changes in technology and applications, they have begun to transform the traditional system of monopoly and its PTT administrations, giant institutions that have received little academic attention. This book, like its companion volume, Television in Europe, deals with the rise and decline of powerful monopolies in the telecommunications field, and dramatic changes that began to take place in the late 1980s. This book is the first comprehensive attempt to address the complicated economic and policy issues of European telecommunications. It describes the historical context in which national state-owned telecommunications monopolies emerged throughout Europe, explores the dynamics of change, and analyzes the forces which continue to transform the traditional PTT system. The discussion covers equipment supply, emerging value-added networks, and new telecommunications-related services within the framework of a detailed country-by-country analysis. It also explores over-arching issues which present special dilemmas for a Europe embarked on economic unification. This highly accessible and comprehensive study will be of interest to students and professionals in the areas of communications, economics, regulatory law, telecommunications engineering, media, and political science

Theoretical models based on the assumption that telecommunications is a natural monopoly no longer reflect reality. As a result, policymakers often lack the guidance of economic theorists. Competition in Telecommunications is written in a style accessible to managers, consultants, government officials, and others. Jean-Jacques Laffont and Jean Tirole analyse regulatory reform and the emergence of competition in network industries using the state-of-the-art theoretical tools of industrial organisation, political economy, and the economics of incentives. The book opens with background information for the reader who is unfamiliar with current issues in the telecommunications industry. The following sections focus on four central aspects of the recent deregulatory movement: the introduction of incentive regulation; one-way access (access given by a local network to the providers of complementary segments, such as long-distance or information services); the special nature of competition in an industry requiring two-way access (whereby competing networks depend on the mutual termination of calls); and universal service, in particular the two leading contenders for the competitively neutral provision of universal service: the use of engineering models to compute subsidies and the design of universal service auctions. The book concludes with a discussion of the Internet and regulatory institutions.
