On this episode of Ruled by Reason, Emily Bridges of the Food and Agriculture Impact Project has a wide-ranging discussion with antitrust scholar Peter Carstensen about the role of information exchange in restricting competition in agricultural markets, focusing on how the DOJ’s case against Agri-Stats addresses that threat.

After covering the oligopolistic nature of many agricultural markets (2:45), the two do a deep dive on why information exchange can be so harmful to competition (11:04). Professor Carstensen explains how the law on information exchange has evolved and how that history has led to unfortunate ambiguity about the applicable standard (17:10).

Professor Carstensen then explains why information exchange has been a particular problem in agricultural markets. He describes how recent cases in this area, including both private actions and the DOJ’s case against the information aggregator, Agri-Stats, can play an important role in clarifying and strengthening enforcement against unjustified information exchanges (27:20). The discussion concludes with some thoughts about what we can expect from current trends in litigation over illegal information exchanges (48:50).
