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...

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 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...

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 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...

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...

Research and development (R&D) is a common process in for-profit organizations. Despite the benefits, it is not routinely practiced in nonprofit organizations, in part because it is difficult to identify the effects of programs that are designed to involve individuals over long periods of time....

Recently the software industry has experienced fundamental changes in market structure through the entry of open source competitors, e.g. Linux's entry into the operating systems market. In a simple model we examine the effects of such a change in market structure from monopoly to duopoly under...

In response to increasing health expenditures and a high number of physician visits, the German government introduced a copayment for ambulatory care in 2004 for individuals with statutory health insurance (SHI). Because persons with private insurance were exempt from the copayments, this health...

Open source software (OSS) is a public good. A self-interested individual would consider providing such software, if the benefits he gained from having it justified the cost of programming. Nevertheless each agent is tempted to free ride and wait for others to develop the software instead. This...
