The series aims to cover topical policy issues in economics from a largely European perspective. The books in this series are the products of the papers and intensive debates that took place during the seminars hosted by CESifo, an international research network of renowned economists organized jointly by the Center for Economic Studies at Ludwig-Maximilians- Universität, Munich, and the Ifo Institute for Economic Research. All publications in this series have been carefully selected and refereed by members of the CESifo research network. Introduction Economic analysis now plays a crucial role in formulating antitrust policy (referred as competition policy in Europe) across the Atlantic, and courts have endorsed a central role for economic theory and empir- ical analysis in rendering their decisions. For instance, economic con- cepts are widely adopted in the U.S. Merger Guidelines, and the recent discussion of European merger reform also mirrors this trend, with more emphasis on economics-based merger enforcement. In addition, antitrust court cases are increasingly argued with sophisticated eco- nomic analysis by all parties concerned. In major cases such as Eastman Kodak Co. v. Image Technical Services, Inc. and the US v. Microsoft, both plaintiffs and defendants made extensive use of game theory, the eco- nomics of information, and transaction cost economics in advancing their arguments.1 The need for sophisticated economic reasoning is reflected in the substantial presence of economists in antitrust agencies and major consulting firms. Two U.S. antitrust agencies, the Department of Justice and the Federal Trade Commission, each employ fifty to sixty PhD-level economists headed by Chief Economists who are usually respected academics. As part of the reform process, the European Commission also recently created the position of Chief Economist. Against this background, this book brings together a panel of spe- cialists to discuss the conceptual and empirical issues involved in the formulation and enforcement of competition policy. The chapters in the book reflect the wide range of issues in antitrust analysis and provide a broad picture of recent developments by discussing the current state of the art and identifying avenues for further research. The first set of three chapters deals with theoretical issues that have played important roles in recent antitrust cases such as Eastman Kodak Co. v. Image Technical Services, Inc., et al., the Visa and MasterCard
