This casebook provides an overview of trade regulation, including an integrated discussion of the major antitrust guidelines from the Department of Justice and the Federal Trade Commission during the 1990s and significant antitrust process issues. The book's comparative law materials reflect expanded antitrust systems of other nations, and a series of economic essays and notes offer views on antitrust policy development. The casebook offers hypothetical problems throughout as a teaching aid. Highlights of the new edition include full integration of Supreme Court cases into appropriate sections of the casebook; important Court of Appeals and District Court opinions; important merger cases; increased attention on cases and scholarship relating to the intersection between antitrust and intellectual property; additional Department of Justice (DOJ) and Federal Trade Commission (FTC) guidelines; and an expanded section on extraterritorial reach and comity.
