In many economic sectors - the digital industries being first and foremost - the market power of dominant firms has been steadily increasing and is rarely challenged by competitors. Existing competition laws and regulations have been unable to make markets more contestable. The book argues that a new competition tool is needed: market investigations. This tool allows authorities to intervene in markets which do not function as they should, due to market features such as network effects, scale economies, switching costs, and behavioural biases. The book explains the role of market investigations, assesses their use in the few jurisdictions where they exist, and discusses how they should be designed. In so doing, it provides an invaluable and timely instrument to both practitioners and academics.

This is the first book to provide a systematic treatment of the economics of antitrust (or competition policy) in a global context. It draws on the literature of industrial organisation and on original analyses to deal with such important issues as cartels, joint-ventures, mergers, vertical contracts, predatory pricing, exclusionary practices, and price discrimination, and to formulate policy implications on these issues. The interaction between theory and practice is one of the main features of the book, which contains frequent references to competition policy cases and a few fully developed case studies. The treatment is written to appeal to practitioners and students, to lawyers and economists. It is not only a textbook in economics for first year graduate or advanced undergraduate courses, but also a book for all those who wish to understand competition issues in a clear and rigorous way. Exercises and some solved problems are provided.

The most controversial area in competition policy is that of exclusionary practices, where actions are taken by dominant firms to deter competitors from challenging their market positions. Economists have been struggling to explain such conduct and to guide policy-makers in designing sensible enforcement rules. In this book, authors Chiara Fumagalli, Massimo Motta, and Claudio Calcagno explore predatory pricing, rebates, exclusive dealing, tying, and vertical foreclosure, through a blend of theory and practice. They develop a general framework which builds on and extends existing economic theories, drawing upon case law, discussions of cases and other practical considerations to identify workable criteria that can guide competition authorities to assess exclusionary practices. Along with analyses of policy implications and insights applied to case studies, the book provides practitioners with non-technical discussions of the issues at hand, while guiding economics students with dedicated technical sections with rigorous formal models.
