In the wake of World War II, the United States devoted considerable resources to building a liberal economic order, which Washington believed was necessary to preserving not only prosperity but also peace after the war, and antitrust was a cornerstone of that policy. This fascinating book shows how the United States sought to impose its antitrust policy on other nations, especially in Europe and Japan.

The book presents a modern approach to understanding U.S. antitrust law, illuminating the economic analysis that dominates modern antitrust analysis in a straightforward way that minimizes technical jargon and makes the underlying economic concepts accessible to a broad audience. The cases are carefully edited to present the facts and issues clearly and succinctly, with the focus on extensive questions that probe those issues and show how to apply modern antitrust economic analysis to them. The result is a book that is quite compact, fewer than 800 pages, but covers the full waterfront of antitrust issues and generates plenty of multi-layered points and ideas to fill a class. Throughout the book incorporates important Supreme Court antitrust cases and agency guidelines. The merger section focuses on modern agency practices and merger theories, and selected cases that illustrate them, rather than on outdated Supreme Court cases that no longer describe current merger enforcement.

This newly updated casebook provides an historical fromework showing how modern antitust law has developed across time, giving students a basis for projecting the direction that it is moving and what older arguments still have applicability. This edition includes new cases such as Trinko, Empagran and the continuing story of Microsoft. The text also gives more treatment to merger practice and a practitioner's need to consider the international implications of a client's conduct .
