The Foundations of Antitrust: Events, Ideas, and Doctrines approaches antitrust in a novel way to provide students and practitioners with a foundation for analyzing antitrust issues in the twenty-first century. The book is organized around events, ideas, and doctrines, rather than practices or cases. Part I examines developments in the economy prompting antitrust law, as well as the public policy debates, presidential politics, legislation, and the landmark cases of the formative era. Part II explores ideas that shaped antitrust policy, including early economic thought and the Chicago School. Part III examines the core doctrines of antitrust law, their common law antecedents, the application of antitrust to today's tech giants, and the global reach of U.S. antitrust law. Gregory J. Werden is retired from his position as Senior Economic Counsel in the Antitrust Division of the U.S. Department of Justice.
