There have been major shifts in the framework of social policy and welfare across Europe. Adopting a multi-level, comparative and interdisciplinary approach, this book develops a critical analysis of policy change and welfare reform in Europe. The book applies a dynamic and change oriented perspective to shed light on policy changes that are often poorly understood in the welfare literature, and contributes to a further development of the theoretical and conceptual frameworks for understanding social change. Using citizenship as a focus, several dimensions of change are analysed simultaneously: changes in the discipline of social policy itself; the changing character of social problems; changes in social policy and citizenship; and the emergence of new forms of social integration. The book also speculates on how different dimensions of change are interlinked.
