Worlds, families, regimes: Country clusters in European and OECD area public policy

This article focuses on the notion that the policies and politics of states and nations constitute distinct worlds or clusters. We begin by examining the concept of clustering as it has emerged in the literature on policy regimes and families of nations. We then address a series of empirical questions: whether distinct worlds persist in an era of policy convergence and globalisation, whether policy antecedents cluster in the same ways as policy outcomes and whether the enlargement of the EU has led to an increase in the number of worlds constituting the wider European polity. Our main conclusions are that country clustering is, if anything, more pronounced than in the past, that it is, in large part, structurally determined and that the EU now contains a quite distinct post-Communist family of nations.
