The quality of the authors is unparalleled, which explains the sophistication of the book....the book provides an excellent integrated legal and economic analysis of UK merger assessment. Such an analysis is necessary. In addition, the analysis of the different types of markets where a merger can induce unilateral effects provides significant practical insights in the treatment of such effects. Furthermore, the analysis of public interest mergers as well as the analysis of OFT and CC administrative processes, is detailed and complete, something not found in many similar works....this book provides a comprehensive understanding of the merger control enforcement in the UK, and is an invaluable practical guide for practitioners, policy makers, as well as academics in the fields of competition policy in the UK.
