Beyond Identities: Political Determinants of Support for Decentralization in Contemporary Spain

Support for decentralization has generally been considered an outcome derived from the existence of regional or subnational identities. A recent complementary explanation has highlighted the role of politics to create regionally orientated support. We combine these two explanations by studying what determines the support for decentralization in Spain, an almost unique case where these two approaches can be tested. Using a hierarchical model, we show that in those regions without a different subnational identity, some citizens develop regionally orientated support because of their wish to bring the administration closer to the citizens and because their preferred party is pushing for further decentralization. In addition, we highlight the importance of considering decentralization as an outcome derived from party dynamics, which are able to shape political attitudes towards decentralization.
