Abstract

This chapter surveys seven decades of theorizing about European Union policy-making and policy processes. It begins with a discussion of theories of European integration, including neo-functionalism, intergovernmentalism, liberal intergovernmentalism, institutionalism, constructivism, and postfunctionalism. It then considers the increasing number of studies that approach the EU through the lenses of comparative politics and comparative public policy, focusing on the federal or quasi-federal aspects of the EU and its legislative, executive, and judicial politics. It finally explores the vertical and horizontal separation of powers in the EU and concludes by looking at the ‘governance approach’ to the EU, with emphasis on multi-level governance and EU policy networks, Europeanization, and the question of the EU’s democratic deficit.
