As a consequence of World War II, Austria was divided into four different occupation zones for 10 years. Before tight travel restrictions came into place, about 11 percent of the population residing in the Soviet zone moved across the demarcation line. We exploit this large internal migration...

The East-West gap in the German population is believed to originate from migrants escaping the socialist regime in the German Democratic Republic (GDR). We use newly collected regional data and the combination of a regression discontinuity design in space with a difference-in-differences...

Populous communities often prefer more government involvement than less populous communities, but does community size per se affect citizens' preferences for government? Endogeneity commonly prevents testing for causal effects because (i) people can select into communities while (ii) government...

German separation in 1949 into a communist East and a capitalist West and their reunification in 1990 are commonly described as a natural experiment to study the enduring effects of communism. We show in three steps that the populations in East and West Germany were far from being randomly...

In this study we evaluate the role that Mediterranean Medieval trade with Africa and the Middle-East still plays today in Italian politics by shaping the attitudes towards migrants of individuals that live close to Medieval ports. Trade connections between Medieval ports and Muslim Africa and...

Based on official records from the former East German Ministry for State Security, we quantify the long-term costs of state surveillance on social capital and economic performance. Using county-level variation in the spy density in the 1980s, we exploit discontinuities at state borders to show...

This paper investigates the long-term consequences of mass refugee inflow on economic development by examining the effect of the first large-scale population resettlement in modern history. After the Greco-Turkish war of 1919-1922, 1.2 million Greek Orthodox were forcibly resettled from Turkey...

Creativity is often highly concentrated in time and space, and across different domains. What explains the formation and decay of clusters of creativity? In this paper we match data on thousands of notable individuals born in Europe between the XIth and the XIXth century with historical data on...

Migration contributes to the circulation of goods, knowledge, and ideas. Using community and individual-level data from Moldova, we show that the emigration wave that started in the late 1990s strongly affected electoral outcomes and political preferences in Moldova during the following decade...

High growth firms (HGFs) are important for job creation and considered to be precursors of economic growth. We investigate how product- and labor-market regulations, as well as the quality of regional governments that implement these regulations, affect HGF development across European regions....
