Pursuant to the House Judiciary Committee’s request for information to aid its inquiry concerning the state of existing antitrust laws, Antitrust Economists, Legal Scholars, and Practitioners offer the following joint submission.
PPI Director of Technology Policy, Alec Stapp reviews the antitrust cases against IBM, AT&T, and Microsoft and discusses what we can learn from them today. He explains the relevant concepts necessary for understanding the history of market competition in the tech industry.
The purpose of this submission is to highlight some of the findings of the relevant scholarship to help to inform the ACCC’s work, and to highlight some of the problems that may arise during the course of the study, given the misconceptions about competition between advertising-funded digital platforms that are common in the media and popular debate today.
