household. In a Malthusian world, this translated into lower population pressure, raising average wages by up to a quarter. The Black Death thus set into motion a virtuous circle of higher wages and fertility decline that underpinned Europe’s high per capita incomes. We demonstrate the...

Can infrastructure investment win "hearts and minds"? We analyze a famous case in the early stages of dictatorship - the building of the motorway network in Nazi Germany. The Autobahn was one of the most important projects of the Hitler government. It was intended to reduce unemployment, and was...

Social capital is often associated with desirable political and economic outcomes. This paper contributes to a growing literature on its "dark side". We examine the role of social capital in the downfall of democracy in interwar Germany. We analyze Nazi Party entry in a cross-section of cities,...

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...

While intermediate inputs account for more than half of a final product's value, intersectoral linkages have been ignored as a source of skill bias. Previous empirical studies have investigated skill demand at the worker-, firm-, and sector-level. This paper integrates intersectoral linkages and...

This paper analyzes how access to imported inputs affects firms in developing countries, where domestically produced high-quality inputs are relatively costly. We build an O-Ring type model with quality complementarity across input tasks, ranking tasks by their quality sensitivity. Because...

What determines whether a new technology will be adopted by a wide array of sectors throughout the economy, turning it into a General Purpose Technology (GPT)? We build a model of endogenous innovation in a setup with heterogenous sectors. These are connected via input-output linkages, so that...

Marriage is amongst the biggest decisions in life. In general, there is a tendency towards assortative matching – people marry others who are relatively similar to themselves. Intermarriage between different social, religious and ethnic groups in most societies is relatively rare (Blossfeld...

Major bubble episodes are rare events. In this paper, we examine what factors might cause some asset price bubbles to become very large. We recreate, in a laboratory setting, some of the specific institutional features investors in the South Sea Company faced in 1720. Several factors have been...
