In Integrating Europe: Informal Politics and Institutional Change the author explains why the European Union (EU) member states actively surrender policy-making power to supranational authorities in unconventional ways. In light of the general antipathy toward giving up national sovereignty inEuropean societies--even where "pro-European" sentiment thrives, why do national governments allow the creation of any new EU laws or policies whose effects they cannot keep under their general control? Why do EU member states allow any sovereignty transfer to occur outside of inter-governmentaltreaties, which are the only legitimate EU bargains found in the EU's formal sphere? Deploying the tools of rational choice institutionalist theory, the author argues that informal bargains struck between the EU's primary organizational actors - the European Council, European Commission, andEuropean Parliament - have paradoxically resulted in increased integration. As the EU is an ideal laboratory for testing different institutionalist hypotheses for explaining institutional change, the author focuses on the ongoing competition to alter the EU rules that allocate power, and, with anapproach that allows for feedback loops among agents and structures, makes an argument that flies in the face of realist and intergovernmentalist theories. While some have shed light on the importance of informal dynamics in the legal sphere of the EU, this book does the same for the policy-makingsphere.
