This volume collects papers that explore institutionalisation in contemporary transatlantic relations. Policy makers, lawyers, and political scientists reflect upon contemporary understandings of the process as an integration of regimes and orders from an EU perspective. The papers assess whether transatlantic relations in contemporary times form a changed study of global governance through its heightened emphasis upon institutionalisation. Coverage features a diversity of case studies of interest to a broad multi-disciplinary audience. In particular, it focuses upon two cutting-edge issues. The first concerns transatlantic data privacy rules that are emerging after the post-Edward Snowdon/ NSA/ PRISM revelations. The second looks at trade through the Transatlantic Trade and Investment Partnership (TTIP) Agreement. The contributors consider these case-studies from a variety of perspectives, honing in upon the dynamism, method, and high politics of transatlantic relations as it has evolved in recent times. They critically explore the common viewpoint that transatlantic relations have been historically considered to be quasi-institutionalised at best or, at most, law-light and institution-light. Is institutionalisation a useful meeting point for all disciplines? Does it explain regional integration meaningfully across subjects? Can institutionalisation serve as a nudge for accountability and good governance? Readers will find the answer to these questions and more inside this volume.
