Corruption and support for decentralisation

Existing explanations of individual preferences for decentralisation and secession focus on collective identity, economic considerations and party politics. This paper contributes to this literature by showing that preferences for fiscal and political decentralisation are also driven by concern about the quality of government in the face of corruption. It makes two claims. Firstly, information on national-level corruption decreases satisfaction with national politicians, and subsequently increases preferences for decentralisation and secession. Secondly, information on regional-level corruption pushes citizens of highly corrupt regions to prefer national retrenchment and unitary states. The effects of this political compensation mechanism crosscut national identities and involve regions that are not ethnically or economically different from the core. We test our argument using a survey experiment in Spain and confirm its cross-national generalisability with data from the European Values Study.     

Systemic polarisation and spatial voting

The controversy between proximity and directional models of issue voting has not been settled. Instead of appointing an ultimate winner, this article explores the conditioning impact of the level of systemic polarisation and provides evidence that proximity is a more relevant determinant of voter behaviour in less polarised systems, whereas there is a centrifugal and directional dynamic in more polarised contexts. By so doing, the article shows how a largely forgotten notion – namely Sartori's idea of the spatial elasticity of the political spectrum – leads to different spatial viewpoints. In distinguishing between party (supply side) and voter (demand side) polarisation, this framework provides a comprehensive picture about the conditions that turn a centripetal electoral dynamic into a purely centrifugal one.
