[ Ezrachi and Stucke] make a convincing argument that there can be a darker side to the growth of digital commerce. The replacement of the invisible hand of competition by the digitized hand of internet commerce can give rise to anticompetitive behavior that the competition authorities are ill equipped to deal withVirtual Competition displays a deep understanding of the internet world and is outstandingly researched. -- Burton G. Malkiel * Wall Street Journal * Traditional competition law is about firms and their activities. The great insight underpinning Ezrachis and Stuckes book is that, in a digital world, competition law will be mostly about algorithms and big data because these are the forces that now determine what happens in online marketplaces. The book focuses on three particular areas in which anticompetitive and manipulative behavior is possible and, in some cases, already evident Ezrachi and Stucke dig deep into the ways in which algorithmic and big-data analytics combine to produce behaviors and outcomes that areor could betroubling for society. They then go on to discuss the extent to which existing competition law and legal precedents mayor may notbe able to address abuses Ezrachi and Stucke have made a convincing case for the need to rethink competition law to cope with algorithmic capitalisms potential for malfeasance. -- John Naughton * The Observer * We owe the authors our deep gratitude for anticipating and explaining the consequences of living in a world in which black boxes collude and leave no trails behind. They make it clear that in a world of big data and algorithmic pricing, consumers are outgunned and antitrust laws are outdated, especially in the United StatesWe can hope the ideas discussed in Virtual Competition get on the political agenda. -- Barry Nalebuff * Science * A fascinating book about how platform internet companies (Amazon, Facebook, and so on) are changing the norms of economic competition. Virtual Competition: The Promise and Perils of the Algorithm-Driven Economy argues that these companies, with their immense data advantage, are effectively making their own rules in the marketplace, beating back new market entrants, and disadvantaging customers. -- Ben Schiller * Fast Company * From price-comparison algorithms to phone operating systems, technology has altered competitive commerce. Lawyers Ariel Ezrachi and Maurice E. Stucke question the democratic consequences of this dual-edged power. * Nature * This highly readable and authoritative account sets out the ways that platforms have replaced the invisible hand with a digitized onea hand that is human-engineered, subject to corporate control and manipulation, and prone to charges of unlawfulnessIt is becoming increasingly apparent that widespread deployment of algorithmic tools can intensify, rather than reduce, the chasm between the wealthy and the vulnerable. This is the issue Ezrachi and Stucke address as behavioral discriminationOverall, they argue, this is corrosive to social welfare, because the more vulnerable among us end up paying more. The authors assessment of where this is heading is of the most sober kind: absent legal intervention, perfect discrimination will likely become the new norm. -- Julia Powles * Times Higher Education * This is a groundbreaking, critical worka major contribution to the field of competition law. -- Frank Pasquale, author of The Black Box Society Ezrachi and Stucke provide a compelling analysis challenging the orthodoxy that modern technology empowers consumers. Their findings will send a shiver down the spine of consumers, businesses, public policy makers and anyone working in the competition field. Virtual Competition is a fast-paced, mind-boggling thriller that you cant put down; a thriller in which we are all set to be the victim. -- Alan Giles, Saïd Business School, University of Oxford Virtual Competition provides an intriguing and provocative look at the potential dark side of big data and big analytics. The debate over digital competition is just beginning, and Ezrachi and Stucke have laid down a marker that is likely to capture wide attention. -- Jonathan Levin, Stanford Graduate School of Business Ezrachi and Stuckes insights into data-driven opportunities, collusion scenarios, discrimination, and frenemies will help authorities distinguish between true efficiencies and anti-competitive problems, and ensure that most enforcement at least keeps up with technological developments. Forward-thinking competition authorities can use these insights proactively to help craft government policies that ensure that innovation and competition are real, while problems are addressed quickly and thushopefullyremain virtual. -- Philip Marsden, Inquiry Chair, Competition and Markets Authority A thought-provoking, clearly written examination of the coming effects on markets and competition of computer algorithms, big data, big analytics, and super-platforms, drawing on real-life examples, on neoclassical and behavioral economics, and on the authors deep understanding of U.S. and EU competition law. -- Harry First, New York University School of Law Equal measures computer science, law, economics, and behavioral science, this book will appeal to all four groups and introduce the concepts in a very enjoyable way. Whether people shop online, on their phones, or in stores, companies track them. What they buy, where they shop, when they shop, and how they shop can all be analyzed by retailers, who can then offer different products, coupons, and discounts. Retailers not only collect and analyze this data but also sell the data and analysis to other companies, sometimes including their competitors. This book delves into the privacy and regulatory complications of this data and analysis. Though readers may be taken aback by just how much information is collected about their shopping habits, this book describes in detail how retailers and marketers use ambivalence to privacy to market products and services at prices consumers are willing to pay. -- J.
