The government fragmentation hypothesis (GFH) states that coalition governments spend more than single-party governments due to an underlying common pool problem. Using a large panel data set on 604 local governments in the German state of Baden-Württemberg for the 1994-2014 period, I test the...

Signature requirements are often used as hurdles to prevent overuse of public referenda. We evaluate the causal effect of lowering signature requirements on the number of observed citizen initiatives. Based on municipality-level data for Germany, we make use of legislative changes at specific...

In many countries, important features of municipal government (such as the electoral system, mayors' salaries, and the number of councillors) depend on whether the municipality is above or below arbitrary population thresholds. Several papers have used a regression discontinuity design (RDD) to...

We study political determinants of municipality amalgamations during a boundary reform in the German state of Brandenburg, which reduced the number of municipalities from 1,489 to 421. The analysis is conducted using data on the political decision makers as well as fiscal and socio-economic...

This paper estimates the effect of political power on tax policies in municipal councils under a proportional election system. The main challenge in estimating the causal effect of parties on policy is to isolate the effect of power from underlying voter preferences and the selection effect of...

Do incumbents in an election have an advantage, and if so, are these advantages heterogeneous across parties or government and opposition? We first present a theoretical discussion on the possible heterogeneity of incumbency effects in a pure two-party system. Then, we estimate the incumbency...

This paper explores the interdependency of political institutions from the voter's perspective. Specifically, we are interested in three questions: (1) Does the partisan identity of the local mayor influence the voter's decision in the subsequent town council election?; (2) Does this partisan...

Theoretical work based on social identity theory and in-group favoritism predicts that increased population diversity (e.g., due to immigration) reduces support for redistributive public policies. In this article, we add to the empirical literature testing this prediction in three ways. First,...

This paper provides empirical evidence on the party incumbency advantage in mayoral elections in Germany. Using a regression discontinuity design on a data set of about 25,000 elections, I estimate a causal incumbency effect of 38-40 percentage points in the probability of winning the next mayor...

This paper explores the interdependency of political institutions from the voter's perspective. Specifically, we are interested in: (1) Does the partisan identity of the mayor influence the voter's decision in the subsequent town council election?; (2) Does this partisan identity influence the...
