This paper analyzes empirically the coalition formation of local governments. We introduce a novel econometric strategy involving choice based sampling from a spatial network to allow for multi-partner mergers in our empirical analysis. We apply our method to recent municipality mergers in...

We use data for 198121 candidates and 1351 random election outcomes to estimate the effect of incumbency status on future electoral success. We find no evidence of incumbency advantage using data on randomized elections. In contrast, regression discontinuity design, using optimal bandwidths,...

We analyze free-riding behavior by Finnish municipalities prior to municipal mergers. The merger process creates a temporary common pool problem, which arises because of a delay from the initial merger decision to the actual merger. Using a difference-in-differences strategy, we find large...

We test whether voters are rational in the sense that their decision to vote depends on its expected impact on the election outcomes. By using exogenous variation in pivotal probabilities that arise at population thresholds determining council sizes in Finnish municipal elections, we provide the...
