This book provides a critical analysis of damages claims for the infringement of EU competition law by combining a theoretical with a practical perspective. The work focuses on the relevant EU framework, focusing on the recently adopted directive, examining all aspects of EU law that may be relevant to damages claims (whether brought by a consumer or not), including an analysis of the rarely examined causation aspects, alternative dispute resolution, as well as private international law instruments. The book also delves into the economic underpinnings of claims for damages, including optimal enforcement theory and damages and the legal standards of liability, the evaluation of damages for cartels, exploitative conduct and exclusionary conduct. The interaction between damages claims and public enforcement, as well as issues relating to multi-jurisdictional enforcement and damages claims are also explored in this work.
