This handbook brings together an international roster of competition law scholars and practitioners to address the issue of sanctions in competition law from all angles. Covering nineteen jurisdictions around the world, the book analyzes the theoretical foundations and practice of sanctioning competition law infringements and, most importantly, cartels. Contributors include a range of experts drawing on criminal law, company law, labor law, human rights, and law and economics, to determine what sanctions are available as a matter of positive law against corporations and individuals, including fines and other criminal, administrative, and civil law sanctions; whether law enforcers are using these sanctions effectively; and if new sanctions - including individual sanctions - should be introduced.
