Alexandra Hennessy examines an area of Europeanization that has been largely ignored by political analysts: the development of an internal market for workplace pensions. This book offers an analysis of what is at stake in workplace pension reforms, tracing how different states approached them and how national political economy models have shaped actors' bargaining strategy at the EU level. Employing statistical analysis, formal modelling, and in-depth case study research, Hennessy highlights the role of informal signalling and communication processes in designing a common pension market. This book offers a theoretical framework that accounts for historical institutionalism, informal signalling processes and discourse in the Europeanization of workplace pensions – a must-read for students of comparative social and public policy, comparative politics and European politics.
