This book combines practical guidance and theoretical background for analysts using empirical techniques in competition and antitrust investigations. Peter Davis and Eliana Garcés show how to integrate empirical methods, economic theory, and broad evidence about industry in order to provide high-quality, robust empirical work that is tailored to the nature and quality of data available and that can withstand expert and judicial scrutiny. Davis and Garcés describe the toolbox of empirical techniques currently available, explain how to establish the weight of pieces of empirical work, and make some new theoretical contributions. The book consistently evaluates empirical techniques in light of the challenge faced by competition analysts and academics--to provide evidence that can stand up to the review of experts and judges. The book's integrated approach will help analysts clarify the assumptions underlying pieces of empirical work, evaluate those assumptions in light of industry knowledge, and guide future work aimed at understanding whether the assumptions are valid. Throughout, Davis and Garcés work to expand the common ground between practitioners and academics.

We propose a method for bounding the demand elasticity in growing, homogeneous-product markets that requires only minimal data -- market price and quantity over a time span as short as two periods. Reminiscent of revealed-preference arguments using choices over time to bound the shape of indifference curves, we use shifts in the equilibrium over time to bound the shape of the demand curve under the assumption that growing demand curves do not cross. We apply the method to assess the effectiveness of the antitrust remedy in the 1952 Du Pont decision, ordering the incumbent manufacturers to license their patents for commercial plastics. Commentators have suggested that the incumbents may have preserved the monopoly outcome by gaming the licensing contracts. The upper bounds on demand elasticities that we compute are significantly less than 1 in many post-remedy years. Such inelastic demand is inconsistent with monopoly, suggesting the remedy may have been effective.

This article extends antitrust analysis to two-sided markets in which a virtual monopolist competes with local bricks-and-mortar dealers. The discussion examines the market power of an Internet market maker as well as an Internet matchmaker. The analysis shows that equilibrium in a two-sided market can be characterized as a one-sided market in which transaction demand depends on the bid-ask spread of the central market maker. This allows for a straightforward extension of critical demand elasticity and critical loss analysis from one-sided markets to two-sided markets, with antitrust tests based on the hypothetical monopolist's bid-ask spread. Antitrust analysis of a one-sided market also carries over to a two-sided market with a matchmaker where antitrust tests are based on the sum of participation fees.

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.

"The economic expert has become a central figure in virtually every antitrust litigation or merger matter, and the importance of econometrics has increased significantly. A basic understanding of econometric principles has now become almost essential to the serious antitrust practitioner. This volume is designed to introduce lawyers to the theoretical and practical issues of econometrics, providing necessary tools for working effectively with economic experts on both sides of a matter." -- from the Foreword, p. xv.
