This new edition casebook excels at communicating a sense of how antitrust law affects both business decisions and lawyerly practice. It addresses the initial difficulty that most students experience in understanding how the different statutes, doctrinal developments, and economic issues fit together to form a reasonably coherent picture. The authors achieve this by presenting a set of overview materials that provide a clear road map and useful perspectives. The Third Edition of Antitrust Law includes more lower court cases and more "real-world" material such as jury instructions. Although the text is sparing in its presentation of economic models, the authors have also integrated important economics into every part of the text. This casebook shows how a few simple models, as well as more general implications of social-science thinking, yield important insights and also wield much influence in antitrust jurisprudence. The Third Edition includes an expanded use of clarifying visual-aid exhibits to help students better understand complex issues in law as well as economics.
