We investigate the causal impact of equity market liberalizations in the period 1980‐1997 on sectoral export performance across 91 countries. The increased availability of external finance has boosted trade of industries that intensively use relationship‐specific inputs, and lowered exports...

We develop a general equilibrium model of international trade with heterogeneous firms, where countries can invest into basic research to improve their technological potential. These research investments tighten firm selection and raise the average productivity of firms in the market, thereby...

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...

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...

The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a novel framework to address this question at three...

During the last decade there have been marked changes in the composition of the non-native workforce in the German labour market. In particular there has been a notable increase in the diversity of nationalities of which the foreign workforce is composed. In this paper we investigate the effects...
