Cross-national policy convergence: concepts, approaches and explanatory factors

Abstract:

Although there is an increasing number of studies on policy convergence (in recent years especially in the context of Europeanization and globalization research), we still have a rather limited understanding of this phenomenon. This deficit can be not only traced back to a lack of empirical findings, but is also the result of the heterogeneous and partially inconsistent theoretical literature on policy convergence. Although policy convergence constitutes a central concept in comparative public policy, it is not always consistently used and mixed up with related but not equivalent concepts. It is thus a basic objective of this paper to clarify the analytical relationship between policy convergence and related concepts used in the literature. Moreover, different approaches for the assessment and measurement of policy convergence will be presented. The paper concludes with a brief discussion of causes of policy convergence.
