This article tackles the particular issue of split-ticket voting, which has been largely overlooked in Belgian election studies thus far. We contribute to the literature by answering two particular research questions: (1) to what extent and (2) why do voters cast a different vote in the elections for the provincial council as compared to their vote in the elections for the municipal council?
The article draws on survey data collected via an exit poll in the ‘Belgian Local Elections Study’, a research project conducted by an inter-university team of scholars.
Our analysis shows that nearly 45% of the total research population cast a split-ticket vote in the local elections of 2018. However, this number drops to one out of four if we only consider a homogenous party landscape at both levels by excluding the numerous votes for ‘local’ lists (which occur mostly at the municipal level). This finding underlines the importance of accounting for the electoral and institutional context of the different electoral arenas in research on split-ticket voting in PR systems. In the Belgian context, split-ticket voting in 2018 also differed between the different parties and regions. Furthermore, it was encouraged by a higher level of education and familiarity with particular candidates. This candidate-centred and strategic voting was matched by party identification and the urban municipal context favouring straight-ticket voting. Other factors such as region, a rural municipal context and preferential voting seemed more relevant to determine voting for local parties than using the instrument of split-ticket votes as such.

Fiscal consolidation confronts federal states with a collective action problem, especially in federations with a tightly coupled fiscal regime such as Belgium. However, the Belgian federation has successfully solved this collective action problem even though it lacks the political institutions that the literature on dynamic federalism has identified as the main mechanisms through which federal states achieve cooperation across levels of government. This article argues that the regionalization of the party system, on the one hand, and the rationalization of the deficit problem by the High Council of Finance, on the other, are crucial to understand how Belgium was able to solve the collective action problem despite its tightly coupled fiscal regime and particularly high levels of deficits and debts. The article thus emphasizes the importance of compromise and consensus in reducing deficits and debts in federal states.
