Dealing with general economic theory, other than employment theory, the book discusses the theory of pure and monopolistic competition - with a special emphasis upon welfare aspects. Beginning with an analysis of the consumer and of the individual firm, the main stress is nevertheless placed on the analysis of the economic system as a whole.

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.

Many parts of the world are currently experiencing the outcome of processes of economic integration, globalization and transformation. Technological advances in telecommunications and in transport facilities have opened up new possibilities for contracts and exchanges among regions. External effects among regions have increased in importance. As a result, competition among regions has intensified. Except some pioneering work by regional scientists and scholars of public finance and economics, the phenomenon of regional competition has yet to attract the attention it warrants, despite its importance for policy-making. The present volume is intended to remedy this neglect by providing high-level contributions to the three main topics of the book, the theory of regional competition, methods of analysis of regional competition and policies of regional competition

For the past two decades, Michael Porter's work has towered over the field of competitive strategy. On Competition, Updated and Expanded Edition brings together more than a dozen of Porter's landmark articles from the Harvard Business Review. Five are new to this edition, including the 2008 update to his classic "The Five Competitive Forces That Shape Strategy," as well as new work on health care, philanthropy, corporate social responsibility, and CEO leadership. This collection captures Porter's unique ability to bridge theory and practice. Each of the articles has not only shaped thinking, but also redefined the work of practitioners in its respective field. In an insightful new introduction, Porter relates each article to the whole of his thinking about competition and value creation, and traces how that thinking has deepened over time. This collection is organized by topic, allowing the reader easy access to the wide range of Porter's work. Parts I and II present the frameworks for which Porter is best known--frameworks that address how companies, as well as nations and regions, gain and sustain competitive advantage. Part III shows how strategic thinking can address society's most pressing challenges, from environmental sustainability to improving health-care delivery. Part IV explores how both nonprofits and corporations can create value for society more effectively by applying strategy principles to philanthropy. Part V explores the link between strategy and leadership
