We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

We analyze an oligopolistic market where a domestic and a foreign firm are engaged in a takeover battle for a domestic competitor. Any merger or acquisition (M&A) must be approved by a welfare maximizing domestic competition agency which may or may not be prone to "economic patriotism". A...

We address the effects of wages on employment growth on the basis of a theoretical model from which cost and demand effects can be derived. In the empirical analysis we take a highly disaggregated perspective and apply a newly developed shift-share regression technique on an exhaustive and very...

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...

We analyze how globalization has affected the sectoral anatomy of regional growth in Germany over the period 1978-2008. The aggregate German economy is characterized by a secular decline of manufacturing and a rise of modern service industries. This trend– also known as Petty's law – is not...

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...

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 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 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...
