This revised and updated Research Handbook on European State Aid Law brings together established academics and practitioners to provide a wide-ranging coverage of the field. Incorporating political science, economics and the law in its analysis, it provides a strong overview of the salient issues in State aid law and policy. Chapters address the significance of State aid to various aspects of the political and legal systems of the Member States, including taxation, the financial sector, and the interplay between EU rules on State aid, free movement and public procurement. The Research Handbook further examines the application of the State aid rules to major sectors of the EU economy and introduces brand new themes for State aid analysis, such as arbitration, social services and the impact of Brexit. Featuring theoretical explorations and empirical studies, this Research Handbook will be crucial reading for scholars and researchers of EU State aid law, especially those searching for new avenues of research. It will also be a useful reference point for officials in national governments and the European Commission who are engaged in the State aid approval process. Judges hoping to expand their knowledge of EU State aid law and policy will also benefit from this insightful Research Handbook.
