There has been vast interest in the distribution of city sizes in an economy, but this research has largely neglected that cities also differ along another fundamental dimension: age. Using novel data on the foundation dates of more than 10,000 American cities, we find that older cities in the...

We characterize the equilibrium and optimal resource allocations in a general equilibrium model of monopolistic competition with multiple asymmetric sectors and heterogeneous firms. We first derive general results for additively separable preferences and general productivity distributions, and...

Headquarters and their specialized component suppliers have a vital interest in establishing long-term collaborations. When formal contracts are not enforceable, such efficiency-enhancing cooperations can be established via informal agreements, but relational contracts have been largely ignored...

This paper addresses the impact of rising international trade exposure on individual earnings profiles in heterogeneous worker-establishment matches. We exploit rich panel data on job biographies of manufacturing workers in Germany, and apply a high-dimensional fixed effects approach to analyze...

Using comprehensive data for German establishments, we estimate plant-evel production functions to analyze if cultural diversity affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate labor force of the region where the plant is located....

We develop a theory of a firm in an incomplete contracts environment which decides on the complexity, the organization, and the global scale of its production process. Specifically, the firm decides i) how many intermediate inputs are simultaneously combined to a final product, ii) if the...

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...

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

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 trade...

In this paper, we consider a dynamic search-and-matching problem of a firm with its intermediate input supplier. In our model, a headquarter currently matched with a supplier, has an interest to find and collaborate with a more efficient partner. However, supplier switching through search and...
