This text organizes cases over four periods: a 25-year period from 1890 to 1914, in which most of today's issues were foreshadowed; a 25-year period from 1915 to 1939, in which the 'rule of reason' forced courts to investigate the actual consequences of business practices; a 35-year period from 1940 to 1975, in which the per se rule and industry concentration provided the predominant models for analysis; and the modern period of over 40 years, which is a synthesis of the second and third periods. The new Seventh Edition describes the many major changes in antitrust law and policy that the present leaders of the FTC and the Antitrust Division at the Department of Justice are attempting to make and includes questions after many of the modern cases that require students to evaluate those proposed changes. The new edition includes all of the important recent court opinions, including the Supreme Court's opinions in Ohio v. American Express and NCAA v. Alston and the D.C. Circuit's opinion in U.S. v. AT&T.
