This innovative and popular casebook focuses on teaching antitrust through the best legal precedents available. It emphasizes current judicial opinions and includes dissents where relevant to help students grasp the issues. The notes reflect a balanced approach to the competing ideologies of left, right, and center--confronting their defects and presenting their strengths. Professors who are strongly committed to a particular ideology should find plenty of material to criticize or, alternatively, to illustrate their view. The ninth edition of the casebook is being published on the 40th anniversary of the publication of the inaugural edition of this leading antitrust casebook. Specific updates for this edition include: Updates on the cyclical nature of antitrust endorsement theories and trends, with a focus on the Biden administration, including a return to a progressive neo-Brandeis antimonopoly approach concerning increased economic power and its effect on concentration in the marketplace affecting consumers and workers and leading to inequality in society and ultimately democracy.
