In the field of antitrust, the freedoms to contract and compete can and do contradict. Profit-maximizing companies desire perfectly competitive input markets to minimize their costs, but want monopolistic markets for their outputs to maximize their profits. Consequently, they have strong incentives to undermine competition in their output markets. In a world without antitrust laws, many companies would thus eliminate competition by using their freedom to contract, either by entering into legally enforceable agreements which fix prices or divide up markets, or by merging and acquiring rivals to gain market control. Therefore, guaranteeing and safeguarding companies' abilities to compete comes at the cost of restricting their freedoms to contract. The states role in this task is a delicate one though: government intervention itself necessarily limits the economic freedom of individuals and firms, and limiting the freedom of contract has potentially detrimental effects on economic activity as well. Hence, antitrust policy must find the right balance between the two freedoms of competition and contract, allowing competition to flourish while upholding the contractual freedoms necessary for a functioning market. The policies in the U.S. and Europe used to protect competition with per se rules, setting clear boundaries for the freedom to contract where it interfered with the freedom to compete. Over the past decades, improvements in economic analysis provided measurable dimensions for 'competition' through measures like efficiency and welfare. With these new and complex economic tools, the aim of an antitrust policy moved away from an 'indirect' mechanism which provided and enforced a strict framework of negative per se rules within which the competitive process was allowed to happen. The current policies directly aim at promoting welfare by attempting to 'balance' the welfare effects of individual business practices, permitting contracts or mergers with benign effects and prohibiting contracts with detrimental effects on welfare in potentially every case. These economic insights have promoted a better understanding of the competitive process and contributed to improved antitrust rules. However, in the actual enforcement of antitrust laws, recent developments caused by the influence of economic analysis have had a detrimental impact on antitrust policy in both the U.S. and the EU. First, it increased the discretion of competition authorities, lowering legal certainty for companies and increasing the potential for wrong decisions. Second, it gave companies incentives to waste resources on rent seeking activities by using economic analyses to demonstrate efficiencies in complicated and timely investigations and litigation. And third, the predominant use of economic analysis has massively increased the costs of enforcement. This thesis is the first one to depict these negative effects caused by recent developments and shows that a policy with clear limitations through proposed per se rules would be superior for it would eliminate the illustrated negative effects.

In this outstanding new book Professor Keith Hylton and his collaborators examine what antitrust law has become over the past ten years, a time in which economic analysis has become its undisputed core. What has become of the old antitrust doctrine, what are the new issues for the immediate future? This book brings together the leading experts to examine this silent revolution at the core of US domestic policy. Mark Grady, UCLA School of Law, US Hylton s Antitrust Law and Economics brings together many of the best authors writing in antitrust today. Their essays range widely, covering proof of agreement under the Sherman Act, group boycotts, monopolization and essential facilities, tying and other vertical restraints, and merger policy. The writing is clear, accessible but still technically sophisticated and comprehensive. This book represents the best in contemporary antitrust scholarship, by authors who understand and are able to communicate the centrality of economic analysis to antitrust. No antitrust lawyer, serious antitrust student, or antitrust economist should be without this book. Herbert Hovenkamp, University of Iowa College of Law, US This comprehensive book provides an extensive overview of the major topics of antitrust law from an economic perspective. Its in-depth treatment and analysis of both the law and economics of antitrust is presented via a collection of interconnected original essays. The contributing authors are among the most influential scholars in antitrust, with a rich diversity of backgrounds. Their entries cover, amongst other issues, predatory pricing, essential facilities, tying, vertical restraints, enforcement, mergers, market power, monopolization standards, and facilitating practices. This well-organized and substantial work will be invaluable to professors of American antitrust law and European competition law, as well as students specializing in competition law. It will also be an important reference for professors and graduate students of economics and business.

A substantially revised and updated new edition of the leading text on business and government, with new material reflecting recent theoretical and methodological advances; includes further coverage of the Microsoft antitrust case, the deregulation of telecommunications and electric power, and new environmental regulations. This new edition of the leading text on business and government focuses on the insights economic reasoning can provide in analyzing regulatory and antitrust issues. Departing from the traditional emphasis on institutions, Economics of Regulation and Antitrust asks how economic theory and empirical analyses can illuminate the character of market operation and the role for government action and brings new developments in theory and empirical methodology to bear on these questions. The fourth edition has been substantially revised and updated throughout, with new material added and extended discussion of many topics. Part I, on antitrust, has been given a major revision to reflect advances in economic theory and recent antitrust cases, including the case against Microsoft and the Supreme Court's Kodak decision. Part II, on economic regulation, updates its treatment of the restructuring and deregulation of the telecommunications and electric power industries, and includes an analysis of what went wrong in the California energy market in 2000 and 2001. Part III, on social regulation, now includes increased discussion of risk-risk analysis and extensive changes to its discussion of environmental regulation. The many case studies included provide students not only pertinent insights for today but also the economic tools to analyze the implications of regulations and antitrust policies in the future.The book is suitable for use in a wide range of courses in business, law, and public policy, for undergraduates as well at the graduate level. The structure of the book allows instructors to combine the chapters in various ways according to their needs. Presentation of more advanced material is self-contained. Each chapter concludes with questions and problems.

One might mistakenly think that the long tradition of economic analysis in antitrust law would mean there is little new to say. Yet the field is surprisingly dynamic and changing. The specially commissioned chapters in this landmark volume offer a rigorous analysis of the field's most current and contentious issues. Focusing on those areas of antitrust economics that are most in flux, leading scholars discuss topics such as: mergers that create unilateral effects or eliminate potential competition; whether market definition is necessary; tying, bundled discounts, and loyalty discounts; a new theory of predatory pricing; assessing vertical price-fixing after Leegin; proving horizontal agreements after Twombly; modern analysis of monopsony power; the economics of antitrust enforcement; international antitrust issues; antitrust in regulated industries; the antitrust-patent intersection; and modern methods for measuring antitrust damages. Students and scholars of law and economics, law practitioners, regulators, and economists with an interest in industrial organization and consulting will find this seminal Handbook an essential and informative resource.

Antitrust law regulates economic activity but differs in its operation from what is traditionally considered "regulation." Where regulation is often industry-specific and involves the direct setting of prices, product characteristics, or entry, antitrust law focuses more broadly on maintaining certain basic rules of competition. In these lectures Michael Whinston offers an accessible and lucid account of the economics behind antitrust law, looking at some of the most recent developments in antitrust economics and highlighting areas that require further research. He focuses on three areas: price fixing, in which competitors agree to restrict output or raise price; horizontal mergers, in which competitors agree to merge their operations; and exclusionary vertical contracts, in which a competitor seeks to exclude a rival. Antitrust commentators widely regard the prohibition on price fixing as the most settled and economically sound area of antitrust. Whinston's discussion seeks to unsettle this view, suggesting that some fundamental issues in this area are, in fact, not well understood. In his discussion of horizontal mergers, Whinston describes the substantial advances in recent theoretical and empirical work and suggests fruitful directions for further research. The complex area of exclusionary vertical contracts is perhaps the most controversial in antitrust. The influential "Chicago School" cast doubt on arguments that vertical contracts could be profitably used to exclude rivals. Recent theoretical work, to which Whinston has made important contributions, instead shows that such contracts can be profitable tools for exclusion. Whinston's discussion sheds light on the controversy in this area and the nature of those recent theoretical contributions. Sponsored by the Universidad Torcuato Di Tella

This book provides a thorough treatment of the economic theory that guides and motivates the design and enforcement of American antitrust laws. Along with a comprehensive analysis of both horizontal and vertical antitrust issues, economic theory is used to evaluate antitrust policy through theexamination of relevant legislation and landmark cases. Theory is discussed through its relation to policy issues, and in turn, the role of theory in the development of new policy is examined.
