Ariel Ezrachi is the Slaughter and May Professor of Competition Law and a Fellow of Pembroke College, Oxford. He serves as the Director of the University of Oxford Centre for Competition Law and Policy. Ezrachi is the co-author, editor, and co-editor of numerous books including Virtual Competition: The Promise and Perils of the Algorithm Driven Economy, EU Competition Law: An Analytical Guide to Leading Cases, and most recently Competition Overdose: How Free Market Mythology Transformed Us From Citizen Kings to Market Servants (Harper Business).

In his recent book, told through a captivating exposé, Ezrachi and co-author Maurice E. Stucke show through vivid examples how society overprescribed competition as a solution and when unbridled rivalry hurts consumers, kills entrepreneurship, and increases economic inequality. These two free-market thinkers diagnose the sickness caused by competition overdose and provide remedies that will promote sustainable growth and progress for everyone, not just wealthy shareholders and those at the top.

Ezrachi develops training and capacity building programs in competition law and policy for the private and public sectors, including training programs for European judges endorsed and subsidized by the European Commission. He regularly presents to audiences across the globe on matters relating to competition, digitalism, and capitalism.

Praise for Competition Overdose:

“Stucke and Ezrachi’s analysis of the nature of competition is refreshingly non-ideological and counterintuitive. Their idea that competition can be either toxic or noble—all depending on how governments structure markets—is something so clear that it’s remarkable it’s taken us decades to recognize the wisdom of it. This is a must-read for anyone interested in how to use public policy to harness the competitive drive for the public good.”
--Chris Hughes, cofounder of Facebook

“Entertaining and thought-provoking, Competition Overdose fiercely articulates the raw, hard truth behind the toxic aspects of competition.”
--Tommaso Valletti, professor of economics at Imperial College London and Chief Competition Economist (2016–2019), European Commission

“Anything, in the wrong dosage, can be poisonous. Competition Overdose takes a sacred cow of contemporary western thought—that ‘more competition is always good’—and reveals that while competition can be noble, it can also be toxic. An engaging and compelling read that will make you think differently about situations we all deal with every day.”
--Tim Wu, professor at Columbia Law School, contributing opinion writer for the New York Times, and author of The Master Switch and The Attention Merchants

“A must-read for anyone concerned about the future of our economy and society, Competition Overdose provides a no-nonsense analysis of how toxic competition can be bad for competitors, consumers, workers, and society overall. The authors highlight the abuses of this ideology and remind us that we, as citizens and consumers, can exercise our power by choosing products, based on our values.”
--Monique Goyens, director general of BEUC, The European Consumer Organisation

Competition Overdose is probably the most important book to be published on the subject since The Antitrust Paradox hit bookshelves in 1978. It is destined to transform how governments across the world think about the role of competition in domestic and international policy for decades to come. Stucke and Ezrachi are the new rock stars of competition policy.”
--Ali Nikpay, partner at Gibson Dunn & Crutcher

“This beautifully written book helps us rethink economic principles from the ground up. As any good chemist knows, what can be helpful or harmless in small doses is deadly in excess. While technocrats push competition as a cure to all economic ailments, Stucke and Ezrachi deliver a dose of reality: cutthroat schemes to kneecap rivals, manipulate customers, and exploit workers harm far more than they help. Read this book for a brilliant account of the proper place of competition (and ethics) in society.”
--Frank Pasquale, law professor at University of Maryland and author of The Black Box Society

“Stucke and Ezrachi examine a multitude of perversities in today’s society—colleges striving to recruit applicants they likely will reject, supermarkets stocking hundreds of varieties of jam, travel deals stuffed with hidden fees—and provide a unifying explanation: a misalignment of competition. Their book illuminates how competition can go wrong, and how individuals, businesses, and the government can set it right.”
--Jonathan Levin, dean of Stanford Graduate School of Business
