Increasingly, EU market regulation measures have been introduced in the pursuit of economic justice and welfare. This book illustrates how regulation can help to prevent the abuse of dominance, in particular the abuse of public capital by the state. Comprehensive and interdisciplinary, this book presents the theory of regulation in a highly accessible manner. It explains that whilst the state's ability to make major investments, compete with the private sector and target subsidies may be necessary in supporting infrastructure, the wasteful allocation of public monies can also do immense harm by crowding out private investments, distorting private incentives, and helping to foreclose markets. Against this background, Christian Koenig and Bernhard Von Wendland discuss the strengths and weaknesses of EU regulation in the area of competition in the Internal Market, considering both private and public economic activities and market interventions and providing further analysis in light of global competitive pressures. Contemporary and practical, this book will appeal to academics, students and practitioners interested in regulation both in and outside of the EU. Decision-makers, lawmakers and politicians will also benefit from its strong focus on better law making and regulation in order to promote social welfare.
