The Second Edition builds on the strengths of the first with complete updating of all cases, text, Notes, and Sidebars, taking into account the latest developments and commentary. It includes expanded economic coverage, a thoroughly revised chapter on dominant firm conduct, a thoroughly revised chapter on distribution restraints that comprehensively addresses the Supreme Court's Leegin decision, revised and expanded treatment of the analysis of competitor collaborations and joint ventures, updating of the state-of-the art conspiracy and merger chapters, and increased attention to international and comparative developments. Some older cases have been reduced to notes in favor of newer cases that better reflect current trends in antitrust analysis. Problems and skills exercises have also been refreshed and augmented. Figures and charts have been updated and will be made available in PowerPoint form on the TWEN Author's Forum.
