What determines citizens’ attitudes to municipal mergers?

To what extent can citizens’ attitudes to municipal mergers be explained by costs and benefits incurred by merging with a specific consortium of neighbouring units? To answer this question, we analyse data taken from a survey to citizens of 119 Norwegian local governments in the fall of 2019, merely a few months before the merger of their own unit with one or more neighbouring units was to be implemented as the result of a national local government reform decided over two years in advance. In line with previous studies, we find that citizens tend to prefer merging with wealthier neighbours rather than poorer ones. Moreover, we find that this preference is only observable among respondents in smaller units merging with one or more larger units. Furthermore, differentials in private wealth among the merging units appear to affect preferences more than public wealth. However, we did not find support for the theoretical assumption that citizens prefer mergers with units that are similar in terms of political and societal characteristics. Overall, our study suggests that concerns over local redistributive losses may impede support for mergers and, hence, increase the political costs of implementing comprehensive structural reforms.
