Government termination in multilevel settings. How party congruence affects the survival of sub-national governments in Germany and Spain

Past studies on government survival in parliamentary democracies have been limited to national governments. However, most societies live in a multilevel polity where different policies are decided at distinct governmental layers. So far, the conditions triggering sub-national governments’ termination have remained unexplored. Our paper makes a twofold contribution to the literature. First, we explicitly focus our analysis on the sub-national government level. Second, we expand the analytical scope by assuming a multilevel setting, in which the survival of sub-national governments is dependent on both the party composition of the national government (vertical congruence) and their sub-national peers (horizontal congruence). We test the impact of both congruence measures on the early termination risk of regional governments. Our analysis is complemented by including “traditional” factors from national government termination literature, such as structural attributes of governments and their bargaining environment, into empirical modelling. Analysing a novel dataset on 494 regional governments in Germany and Spain we find that the risk of sub-national government termination is related to varying levels of vertical congruence. Furthermore, we find interesting explanatory variation between the two countries with regard to the effect size of economic performance, regional authority and congruence.
