Federalism and Social Policy focuses on the crucial question: Is a strong and egalitarian welfare state compatible with federalism? In this carefully curated collection, Scott L. Greer, Heather Elliott, and the contributors explore the relationship between decentralization and the welfare state to determine whether or not decentralization has negative consequences for welfare. The contributors examine a variety of federal countries, including Spain, Canada, and the United Kingdom, asking four key questions related to decentralization: (1) Are there regional welfare states (such as Scotland, Minnesota, etc.)? (2) How much variation is there in the structures of federal welfare states? (3) Is federalism bad for welfare? (4) Does austerity recentralize or decentralize welfare states? By focusing on money and policy instead of law and constitutional politics, the volume shows that federalism shapes regional governments and policies even when decentralization exists.
