How persistent are cultural traits? This paper uses data on anti-Semitism in Germany and finds continuity at the local level over more than half a millennium. When the Black Death hit Europe in 1348-50, killing between one third and one half of the population, its cause was unknown. Many...

We present new data documenting medieval Europe's "Commercial Revolution'' using information on the establishment of markets in Germany. We use these data to test whether medieval universities played a causal role in expanding economic activity, examining the foundation of Germany's first...

The paper introduces a framework for studying the hierarchy of growth factors, from deep to more immediate. The specific setting we examine is 18th and 19th century Germany, when institutional changes introduced by reforms and transportation improvements converged to create city growth. We...

I estimate two factor models of Swiss exchange rates during the FirstWorldWar. I have data for five of the primary belligerents: Britain, France, Italy, Germany, and Austria-Hungary. At the outbreak of the war, these nations suspended convertibility of their currencies into gold with the promise...

We study the link between fiscal austerity and Nazi electoral success. Voting data from a thousand districts and a hundred cities for four elections between 1930 and 1933 shows that areas more affected by austerity (spending cuts and tax increases) had relatively higher vote shares for the Nazi...

Using novel microdata, we document an unintended, first-order consequence of the Protestant Reformation: a massive reallocation of resources from religious to secular purposes. To understand this process, we propose a conceptual framework in which the introduction of religious competition shifts...

Can autocracies win electoral support by showcasing economic competence? We analyze a famous case – the building of the Autobahn network in Nazi Germany. Using newly collected data, we show that highway construction was effective in boosting popular support, helping to entrench the Nazi...

Historical accounts suggest that Jewish émigrés from Nazi Germany revolutionized U.S. science. To analyze the émigrés' effects on chemical innovation in the U.S. we compare changes in patenting by U.S. inventors in research fields of émigrés with fields of other German chemists. Patenting...

This paper investigates whether compulsory licensing – which allows governments to license patents without the consent of patent-owners – discourages invention. Our analysis exploits new historical data on German patents to examine the effects of compulsory licensing under the US...

Fiscal deficits, elevated debt-to-GDP ratios, and high inflation rates suggest hyperinflation could have potentially emerged in many European countries after World War I. We demonstrate that economic policy uncertainty was instrumental in pushing a subset of European countries into...
