Antitrust laws have been part of U.S. legislation since the Sherman Act of 1890, and the Clayton and Federal Trade Commission Acts of 1914. Does existing legislation provide a useful framework to check anti-competitive practices today? This week on EconoFact Chats, Dan Richards discusses the many forms of monopoly and monopsony power, how U.S. regulatory attitudes towards anti-trust have shifted, and what tools are available to address monopolistic practices today. Dan is a Professor of Economics at Tufts University.
