'A creative, informative, and highly readable narrative... The book consists of four sections dealing in turn with (1) the law and economics of antitrust policy; (2) the problem of collusion; (3) the question of exclusionary practices; and (4) the difficulties of enforcement... This is a provocative work that judiciously raises pertinent questions about our antitrust policy.'-Robert J. Steamer, Perspective

Markets run on information. Buyers make decisions by relying on their knowledge of the products available, and sellers decide what to produce based on their understanding of what buyers want. But the distribution of market information has changed, as consumers increasingly turn to sources that act as intermediaries for information—companies like Yelp and Google. Antitrust Law in the New Economy considers a wide range of problems that arise around one aspect of information in the marketplace: its quality. Sellers now have the ability and motivation to distort the truth about their products when they make data available to intermediaries. And intermediaries, in turn, have their own incentives to skew the facts they provide to buyers, both to benefit advertisers and to gain advantages over their competition. Consumer protection law is poorly suited for these problems in the information economy. Antitrust law, designed to regulate powerful firms and prevent collusion among producers, is a better choice. But the current application of antitrust law pays little attention to information quality. Mark Patterson discusses a range of ways in which data can be manipulated for competitive advantage and exploitation of consumers (as happened in the LIBOR scandal), and he considers novel issues like “confusopoly” and sellers’ use of consumers’ personal information in direct selling. Antitrust law can and should be adapted for the information economy, Patterson argues, and he shows how courts can apply antitrust to address today’s problems.

From the man who coined the term "net neutrality" and who has made significant contributions to our understanding of antitrust policy and wireless communications, comes a call for tighter antitrust enforcement and an end to corporate bigness.

The stated purpose of antitrust laws is to protect competition and the public interest. But do such laws actually restrict the competitive process, harming consumers and serving the special interests of a few politically-connected competitors? Is antitrust law a necessary defense against the predatory business practices of wealthy, entrenched corporations that dominate a market? Or does antitrust law actually work to restrain and restrict the competitive process, injuring the public it is supposed to protect? This breakthrough study examines the classic cases in antitrust law and demonstrates a surprising gap between the stated aims of antitrust law and what it actually accomplishes in the real world. Instead of protecting competition, this book asserts, antitrust law actually protects certain politically-favoured competitors. This is an essential work for anyone wishing to understand the limitations and problems of contemporary antitrust actions.
