Swiss municipalities that voted on a municipal merger project since the year 2000; source: Strebel, M.A. (2025). “The political economy of territorial integration referendums,” Territory, Politics, Governance 13(3): 344–364.
Under which circumstances do municipalities decide to merge with other municipalities? And what do these territorial reforms deliver? These are the guiding questions of my Ambizione project, funded by the Swiss National Science Foundation, in which I study the causes and consequences of territorial reforms in Switzerland. Since the new millennium, 25% of all Swiss municipalities have disappeared from the map and more than half of them have voted on a municipal merger project they were involved in. I have built a comprehensive dataset of all these popular votes that have been held in Swiss municipalities since the year 2000 (N > 1,500). In combination with other municipal-level data, this dataset allows to assess which kinds of municipalities are predominantly participating in and implementing municipal mergers. Using staggered difference-in-differences and regression discontinuity designs, the main focus of the project is to study the impact of these institutional reforms on the quality of governance and democracy in the affected territories. A lay summary of the project can be found in the research database of the Swiss National Science Foundation.
