The introduction explores the politics and political economy of austerity in comparative perspective, setting out the context of current austerity policies and discourse in Europe. It places the specific exploration of the dynamics and particularities of French austerity politics under Hollande within a broader context of changes since the 1980s to democratic institutions and electoral practices, the politics of European integration and the conditions of complex economic interdependence resulting from processes of deregulation, liberalisation and globalisation. It establishes the rationale behind the focus of the articles in this special issue on, firstly, the link between popular approval of elected politicians, democratic legitimacy and austerity; secondly, the politics and dynamics of state reform processes at the national and subnational levels which are integral to delivering on austerity-oriented commitments to reduce public expenditure; and thirdly, on the increasingly asymmetrical Franco-German relationship whose changing contours have major implications for the politics of austerity in Europe -notably facilitating the dominance of German ordo-liberal economic ideas at the heart of Eurozone crisis responses initiatives.
