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.
