The global financial and economic crisis which started in 2008 has had devastating effects around the globe. It has caused a rethinking in different areas of law, and posed new challenges to regulators and private actors alike. One of the emerging issues is the apparent eclipse of boundaries between different legal disciplines: financial and corporate lawyers have to learn how public law instruments can complement their traditional governance tools; conversely, public lawyers have had to come to understand the specificities of the financial markets they intend to regulate. While commentary on financial regulation and the global financial crisis abounds, it tends to remain within disciplinary boundaries. This volume not only brings together scholarship from different areas of law (constitutional and administrative law, EU law, financial law and regulation), but also from a variety of backgrounds (academia, practice, policy-making) and a number of different jurisdictions. The volume illustrates how interdisciplinary scholarship belongs at the centre of any discussion of the economic crisis, and indeed regulation theory more generally. This is a timely exploration of cutting-edge issues of financial regulation.
