This book provides a comprehensive overview of the economic and competition policy issues that buyer power creates. Drawing on economic analysis and cases from around the world, it explains why conventional seller side standards and analyses do not provide an adequate framework for responding to the problems that buyer power can create. Based on evidence that abuse of buyer power is a serious problem for the competitive process, the book evaluates the potential for competition law to deal directly with the problems of abuse either through conventional competition law or special rules aimed at abusive conduct. The author also examines controls over buying groups and mergers as potentially more useful responses to risks created by undue buyer power.
