This book provides edited selections of primary source material in the intellectual history of competition policy from Adam Smith to the present day. Chapters include classical theories of competition, the U.S. founding era, classicism and neoclassicism, progressivism, the New Deal, structuralism, the Chicago School, and post-Chicago theories. Although the focus is largely on Anglo-American sources, there is also a chapter on European Ordoliberalism, an influential school of thought in post-War Europe. Each chapter begins with a brief essay by one of the editors pulling together the important themes from the period under consideration.
