“…Finally, this study confirms that there are more outsiders in the European periphery, particularly in Southern European countries, than in the core, and that in the European periphery labour market institutions and social protection systems tend to amplify rather than reduce socio-economic risks (Ferrera 1996 ; Schwander & Häusermann 2013 ). This result is relevant for at least two reasons: firstly, because, according to their intensity, new labour market divides may have had different political consequences in different European countries, contributing to explaining the emergence of varieties of populism (Caiani & Graziano 2019 ) and the different re-structuring of party systems in Europe (Hutter et al 2018 ); secondly, and relatedly, because this ‘double dualization’ of Europe—the second referring to socio-economic vulnerabilities in peripheral and core countries drifting apart (Heidenreich 2016 ; Palier et al 2018 )—by increasing European countries’ socio-economic divergence, may have enduring consequences for the process of European integration and, in particular, for the political feasibility of a more social Europe (Ferrera 2017 ).…”
