This detailed book focuses on the development of competition law institutions and contains case studies that examine this against the backdrop of the debate around global convergence of competition law and the limits imposed by particular national circumstances.Five of the chapters examine the development of competition law regimes in a diverse range of countries: Mexico, Hungary, South Africa, Thailand (with comparative remarks on South Korea) and Zambia. The remaining chapters examine the role of multinational institutions, particularly the International Competition Network, and the practice of and potential for regional competition law arrangements. The majority of the authors are seasoned practitioners of competition law, all of whom acknowledge the importance of convergence, while simultaneously demonstrating the limits imposed by divergent national circumstances. This carefully edited collection is a companion volume to Enforcing Competition Rules in South Africa, an account of the development of competition law institutions in South Africa, authored by David Lewis and published by Edward Elgar.Building New Competition Law Regimes will be of particular benefit to scholars, teachers and practitioners of competition law. It will also be of interest to development studies scholars, teachers and practitioners and to specialists in the countries that are the subjects of the case studies.
