’Sometimes when I read edited volumes, I start thinking: have these contributors ever spent a day in the same room, discussing what brings them together and ultimately gives the reader the image of a genuine collective project? I am delighted to see that this collection on the conditions for the emergence of common political order in Europe is entirely coherent, compelling, and delivered in very attractive ways. Jarle Trondal has assembled a world team of researchers at the University of Agder in Kristiansand - This is the product of an integrated group of researchers that shares a vision and a progressive research agenda. The book tackles very big questions that define institutional and organizational analysis: how do common institutions emerge, develop and possibly decline or retrench? And what are the effects of multi-level, variable institutional orders in Europe? The volume is strong on explanation and empirically rich, taking us on a journey via the European public administration, the effects of institutions for accountability like the European Parliament and the European Ombudsman, and the many recombinant forms of regional and municipal cooperation in Europe, cutting across borders and national institutions. There will be huge interest for this volume across public administration, international relations, comparative regionalism, European integration, and institutional analysis.’
