The book explains the purpose of competition policy, introduces the reader to key concepts and techniques in competition law and provides insights into the numerous different issues that arise when analysing market behaviour. Describing the law in its economics and market context, the chapters particularly consider the competition law implications of business phenomena, including distribution agreements, licences of intellectual property rights, cartels, joint ventures and mergers. The book assimilates a wide variety of resources, including judgments, decisions, guidelines and periodical literature. The text has been updated to include the changes to UK law introduced by the Consumer Rights Act 2015, including the reform of collective actions. It also considers the Directive on Antitrust Damages Actions and other measures designed to facilitate private enforcement of competition law. The book also discusses for the first time the application of competition law to price signalling, algorithmic collusion and other atypical cartel activities; it also incorporates extensive new case law and decisional practice at EU and UK level.
