Over the past fifteen years, the optimal enforcement of EU competition law has become a major concern. This book contains a unique collection of articles by lawyers and economists on current issues in the public and private enforcement of competition law. Public enforcement has been strengthened in numerous ways – for example, through the introduction of a leniency programme and a substantial increase in fines for competition law violations. At the same time the EU Commission has been promoting private enforcement – for example, by developing a legal framework that grants victims of EU antitrust law infringements access to compensation. The contributions in this book address a range of topics in the area of competition law enforcement, including the role of fines and leniency programmes in public enforcement; access to evidence and the quantification of damages in private enforcement; and the interaction between public and private enforcement of competition law in Europe.
