Dr. John Connor is an economist and expert witness, recognized as a world authority on price-fixing cartels. He has provided expert testimony in litigation involving industrial economics and antitrust issues, providing analysis of economic damages resulting from anticompetitive business conduct. He has studied the market structure of the dairy industry, supply factors influencing milk prices, and demand characteristics for dairy products generally. He has performed analysis to define and evaluate proposed relevant product markets in antitrust and unfair competition matters involving wholesale grocery products, milk and dairy products, aftermarket automotive sheet metal parts, and natural gas. He has analyzed and estimated the amount of victim restitution following alleged market collusion involving electrical capacitors. His expertise has been applied in price-fixing matters involving lysine, citric acid, niacin, choline chloride, corn sweeteners, bulk vitamins, methionine, smokeless tobacco, cigarettes, sorbates, methyl methacrylate, fed cattle, insulated steel heating pipes, EPDM synthetic rubber, air cargo, and grocery wholesaling.

Dr. Connor is the author of 19 books and monographs and more than 600 other scholarly publications in economics and law. His research has been cited in more than 75 law-review articles, and in five court decisions. His book Global Price Fixing received two national writing awards in 2002 and 2003; new editions were released in 2007 and 2008. A review of the book in the Journal of Economic Literature described it as “…an invaluable reference for those with a deep interest in the economics of cartels, and a very readable and accessible narrative…on international cartels.”

After research posts at the University of Wisconsin and the Economic Research Service of the USDA, Dr. Connor joined Purdue University’s Department of Agricultural Economics in 1983, where he taught industrial and antitrust policy. As a Professor at Purdue, his research focused on international cartels, corporate strategies, price formation, performance outcomes, and the interplay of private decision making with antitrust law and other public policies that influence competition, primarily in the food manufacturing and distribution industries. Since the 1990s, Dr. Connor’s research has emphasized empirical studies of the conduct of international price-fixing cartels in many industries and world-wide antitrust enforcement.

In 2009, his lifetime achievements were recognized when he was awarded the title of Fellow, the highest honor of the Agricultural and Applied Economics Association. In June 2014, he was awarded the Alfred E. Kahn Research Award for Lifetime Achievement by the American Antitrust Institute. Dr. Connor’s current project, the Optimal Deterrence of Cartels, employs the traditional Beckerian legal-economic approach, where he demonstrates that under-deterrence is the norm and over-deterrence is rare. Dr. Connor is Senior Fellow in the American Antitrust Institute, and he consults for government antitrust authorities and law firms in cartel cases. Appointed by the U. S. Department of Justice in December 2013, Dr. Connor serves as a United States representative to the International Competition Network’s Cartel Working Group.
