An economic explanation of the nationalization of electoral politics

The literature on the nationalization of electoral politics focuses on the institutional characteristics of political regimes and the structure and organization of social cleavages. We argue that the nationalization of electoral politics is also driven by economic performance. Economic perturbations increase vote transfers from large (and highly nationalized) parties to small (and weakly nationalized) parties. Permissive electoral systems exacerbate the influence of economic performance on nationalization. Pooled cross-sectional time-series regression analysis is conducted on data from 43 countries and 475 elections between 1950 and 2012. The party-level mechanisms are shown through a closer look at Austria, Portugal and Ireland.The authors acknowledge financial support from the Spanish Minister of Economy and Competitiveness (CSO2013-40723-C2-1-R and CSO2013-47023-C2-2-R)
