Using the airline industry as a case study, this course will explore a number of cutting-edge antitrust issues including (1) new approaches to collusion (such as price fixing through public statements to analysts and using algorithms to set prices), (2) how to evaluate efficiency claims in analyzing mergers and acquisitions in network industries, (3) how to assess challenges to single-firm exclusionary practices (such as predatory pricing and capacity expansions) in network industries, and (4) re-examining the consumer welfare standard that has dominated antitrust for almost 50 years. This course is open to students who have taken or are taking the basic antitrust course.
