ABSTRACT This paper seeks to disentangle analytically the trends towards the subsidiarization of social policies in Europe addressing how the social policy reforms changed actors’ governance arrangements and altered the government scales involved over the last few decades. Following an introductory analysis of the main causes of the subsidiarization of social policies (sections 1 and 2), attention is devoted to the differences between welfare systems in Europe (section 3) and the way they influence the directions of change. The hypothesis is that, despite the fact that the subsidiarization of social policies is a converging rhetoric in most European countries’ social policy reforms, the impact of the process varies according to the specificities of the respective regulatory frames at the national or sub-national scales. This is exemplified in the final part of the paper (section 4) which considers the Italian case and the main critical dimensions that emerge through these processes.
