Since a long time price elasticities of demand form part of the standard toolkit of competition analysis. It is an economic concept measuring the responsiveness of the demand for different goods and services to changes in their prices and is widely used in market definition exercises and horizontal merger control. However, although most antitrust practitioners believe to be familiar with the concept, there are some fundamental characteristics of elasticities stemming from the theory of consumer behavior, which are virtually absent from the antitrust literature and many practitioners are hardly aware of. The purpose of this article is to draw the attention to these properties and to underscore their importance for competition analysis.

"Antitrust law has very rarely been used by workers to challenge anticompetitive employment practices. Yet recent empirical research shows that labor markets are highly concentrated, and that employers engage in practices that harm competition and suppress wages. These practices include no-poaching agreements, wage-fixing, mergers, covenants not to compete, and misclassification of gig workers as independent contractors. This failure of antitrust to challenge labor-market misbehavior is due to a range of other failures-intellectual, political, moral, and economic. And the impact of this failure has been profound for wage levels, economic growth, and inequality. In light of the recent empirical work, it is urgent for regulators, courts, lawyers, and Congress to redirect antitrust resources to labor market problems. This book offers a strategy for judicial and legislative reform"--

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.

Management and legal counsel of foreign companies operating in China as well as those outside China with Chinese business desperately need to keep up with the fast-paced antitrust developments in the most dynamic market in the world. The author of this book, Becky Koblitz, is a seasoned antitrust lawyer for a major U.S. law firm in Beijing. She has decades of legal experience as a prosecutor at the Antitrust Division of the U.S. Department of Justice, as well as in-house counsel for a German subsidiary of a major American real estate development company and as a lawyer at law firms globally. Her rich experience in the U.S., Europe and China, now often regarded as the three centers of global antitrust, makes her the perfect candidate to write a book on China's antitrust development. Her book is a quick read that tells what there is to know about China's antitrust enforcement and includes practical advice and examples for the various aspects of antitrust: dealing with competitors, dealing within the supply chain, mergers, etc. She writes in a straight-forward language such that non-antitrust lawyers can get beyond stock phrases like "illicit price coordination," "abuse of dominance," or "unilateral effect." Her book is a valuable and practical "cookbook" for antitrust compliance training and beyond. Another feature of the book is that it provides both legal and economic perspectives on antitrust analysis in China, which is important given that economic analysis is increasingly adopted by China's antitrust agencies and the Chinese courts. Thus understanding the logic and methodology behind economic analysis as applied to Chinese cases is key to conducting proper antitrust legal analysis that is tailored to the Chinese context. To write a book on the burgeoning antitrust enforcement and practice for the constantly evolving Chinese market is a real challenge. The trick, and it is not as easy as you would think, is to write simple declarative sentences, understandable to the antitrust layman, and at the same time not lose the rigor of antitrust analysis. I think this relatively short book is a remarkable achievement in meeting such a challenge, but I invite you to judge for yourself.
