Are policies from over a century ago that addressed concerns about large trusts like Standard Oil and the American Tobacco Company appropriate today? Or does the source of the market power of high-tech companies like Meta and Alphabet require a new paradigm? Naomi Lamoreaux joins EconoFact Chats to discuss the historical shifts in anti-trust policy from the late 19th and early 20th century to today, and the ongoing tension between rewarding innovation and curtailing anticompetitive activities. Naomi is a senior research scholar at the University of Michigan Law School, and the Stanley B. Resor Professor Emeritus of Economics, and Professor Emeritus of History at Yale University.
