Regulatory competition within Europe and internationally, operates in several fields with different outcomes. This book offers a comparative legal and economic analysis of corporate, securities and competition law, exploring the reasons behind such differences. The book's conceptual framework covers the most relevant drivers of competition, including legal actors' incentives, channels of competition and governance design. It shows how the different drivers and institutional designs are shaping competitive interactions, drawing relevant conclusions for both general and field specific regulatory policy. Providing a comparative analysis of regulatory competition in three legal fields, this book will be a valuable resource for researchers and academics in law, economics and political science, as well as policymakers - legislator, regulator, judiciary - at both national and European levels.
