In the past few years, Latin American countries have taken giant steps to reposition their competition authorities in the global antitrust arena, granting them much greater autonomy both domestically and internationally. This is an updated edition of the first book that offered an in-depth analysis of this complex scenario. The first part of the book includes more general chapters written by leading experts on a variety of relevant topics analyzed at a regional level such as the issues emerging with the digital economy and on the special field of the information and communications technology industry, as well as chapters on broad regional trends, on the working of competition law in countries with regulated markets and in the cluster of Central American countries, among others. At the heart of the presentation are nine chapters detailing the competition regimes of the most active national jurisdictions in the region—Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Paraguay, Peru, and Uruguay. Written by practicing experts with considerable hands-on experience in their respective countries, each of these chapters provides a comprehensive description and explanation of the evolution, current state, and prospects for antitrust in the country. Topics addressed in the country analysis encompass the following and more: relevant institutions and legislation; cartel investigations; unilateral conduct policies; merger review; international coordination; enforcement; and remedies. Each chapter includes an analysis of relevant case law, allowing the reader to gauge the positions, views, and tendencies of each competition law regime. The contributors also pay attention to the specificities and idiosyncrasies that are so important for a correct understanding of the practical realities of competition policy and enforcement. With its wide-ranging and in-depth approach, this book provides an incomparable analysis of a challenging region poised to become increasingly important in the international recognition and enforcement of antitrust law. It is in this sense an essential guide for lawyers, economists, corporations, academics, and government officials interested in understanding where competition law is, and where it is going to, in Latin America.
