Does it matter for municipal fiscal policies which party controls the mayorship in municipal government? The bulk of the existing evidence says no. But there are a variety of theoretical reasons to believe that mayoral partisanship should affect municipal policy outcomes. In this paper, we examine this question using data on nearly 1000 elections in medium and large cities over the past 60 years. In contrast to previous work, we find that mayoral partisanship has a significant impact on the size of municipal government. Overall, Democratic mayors spend more than Republican mayors. The bulk of this additional spending comes on roads, housing, libraries, and interest. We find a modest impact of mayoral partisanship on city tax levels. However, Democratic mayors issue substantially more debt than Republican ones. They also spend much more to service interest on debt. Our findings show that mayoral partisanship matters for city policy. Moreover, our findings add to a growing literature indicating that the constraints imposed on city policymaking do not prevent public opinion and elections from having a meaningful impact on municipal policy.
