I present the first database of historical local population figures for all Germany. The German Local Population Database (GPOP) includes total population in 1871, 1910, 1939, 1946, 1961, 1987, 1996, 2011, and 2019 for the universe of all German municipalities, counties, and states at consistent...

We show that migrating extremists shape political landscapes toward their ideology in the long run. We exploit the unexpected division of the state of Upper Austria into a US and a Soviet occupation zone after WWII. Zoning prompts large-scale Nazi migration to US occupied regions. Regions that...

Voter turnout has declined in many industrialized countries, raising the question of whether electoral institutions increase voter turnout. We exploit an electoral reform in the Austrian state of Burgenland as a natural experiment to identify the causal effect of opening hours of polling...

Do citizens legislate different tax policies than parliaments? We provide quasi-experimental evidence for causal effects of direct democracy. Town meetings (popular assemblies) replace local councils in small German municipalities below a specific population threshold. Difference-in-differences,...

We examine how populist governments influence political culture and economic outcomes. Some Austrian communities are governed by far-right populist mayors, directly elected by a majority of voters. We exploit close elections and find that the electorate becomes more polarized under populist...

Party performance in state and federal elections is highly interdependent. Federal elections impact regional voting dynamics and vice versa (electoral externalities). We quantify the extent of simultaneous electoral externalities between two layers of government. We apply vector autoregressions...

We examine the extent to which political scandals influence trust in electoral institutions in established Western democracies. The second ballot of the 2016 Presidential election in Austria needed to be repeated because of inconsistencies in individual electoral districts (scandal districts)....

We study whether long-gone but activated history can shape social attitudes and behavior even after centuries. We exploit the case of the sieges of Vienna in 1529 and 1683, when Turkish troops pillaged individual municipalities across East Austria. In 2005, Austrian right-wing populists started...

Spatial inequalities in publicly provided goods such as health care facilities have substantial socio-economic effects. Little is known, however, as to why publicly provided goods diverge among urban and rural regions. We exploit narrow parliamentary majorities in German states between 1950 and...

We examine whether compulsory voting influences habit-formation in voting. In Austria, some states temporarily introduced compulsory voting in national elections. We exploit border municipalities across two states that differ in compulsory voting legislation using a difference-in-differences and...
