Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this paper, we show that this trade-promoting effect of language...

We investigate whether time-persistent cultural borders impede economic exchange across regions of the same country. To measure cultural differences we evaluate, for the first time in economics, linguistic micro-data about phonological and grammatical features of German dialects. These data are...

Ever since Sjaastad (1962), researchers have struggled to quantify the psychic costs of migration. We monetize psychic cost as the wage premium for moving to a culturally different location. We combine administrative social security panel data with a proxy for cultural difference based on...

Does it matter if you speak with a regional accent? Speaking immediately reveals something of one's own social and cultural identity, be it consciously or unconsciously. Perceiving accents involves not only reconstructing such imprints but also augmenting them with particular attitudes and...

The German economy exhibits rising service and declining manufacturing employment. But this decline is much sharper in import-competing than in export-oriented branches. We first document the individual-level job transitions behind those trends. They are not driven by manufacturing workers who...

We develop a theory of a firm in an environment with incomplete contracts. The firm's headquarter decides on the complexity, the organization, and the global scale of its production process. Specifically, it decides: i) on the mass of symmetric intermediate inputs that are part of the value...

Why are better educated and more risk-friendly persons more mobile across regions? To answer this question, we use micro data on internal migrants from the German Socio- Economic Panel (SOEP) 2000-2006 and merge this information with a unique proxy for region-pair-specific cultural distances...

Using comprehensive data for German establishments (1999-2008), we estimate plant-level production functions to analyze if “cultural diversity” affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate regional labor force where the...

We analyze the effects of the unprecedented rise in trade between Germany and "the East" – China and Eastern Europe – in the period 1988-2008 on German local labor markets. Using detailed administrative data, we exploit the cross-regional variation in initial industry structures and use...

Recent studies indicate that firms often outsource standard and simple tasks, while keeping complex and important inputs inside their boundaries. This observation is difficult to reconcile with the property rights approach of the firm, which suggests that important components should be...
