International agreements on competition law and policy are notoriously difficult to implement. This collection of essays examines the complexities involved when the issues of international coordination and harmonization of competition law and policy are considered. Presenting an analysis of the debate surrounding cooperation and convergence, a number of key factors are examined. These include the impact of differing antitrust laws across borders on trade and investment, the effects on competition policy of international strategic alliances, mergers and acquisitions, the trade-off between firm privacy and antitrust needs in coordinating information flow across borders. The final section of the book addresses major policy themes in the context of how to proceed in the future.
