This paper examines the difference in productivity between union and nonunion contractors in the construction industry over a sample of 83 commercial office buildings and another sample of 68 elementary and secondary schools. The popular belief that the building trades unions reduce productivity...

Previous studies using micro data to estimate the impact of unions on productivity in construction in the early 1970's have found productivity to be higher for union than nonunion contractors in the private sector. The validity of these studies has been questioned in light of the declining...

This paper examines the effect of unions on efficiency by estimating cost function systems over three different sets of construction projects. The results show that union contractors have greater economies of scale. This gives them a cost advantage in large commercial office buildings, but in...

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...
