Ausgangspunkt dieser Arbeit ist die Behauptung, dass der migrationspolitische Diskurs zu wenig auf die internationale Integration von Gütermärkten Bedacht nimmt. Die Debatte wird weitgehend arbeitsmarktökonomisch geführt, wobei der sogenannte immigration surplus für das Zuwanderungsland und...

Eastern enlargement of the EU promises gains, but also imposes fiscal costs on incumbent countries. A sensitive issue concerns immigration, jobs and wages. We address these issues in a general equilibrium framework, both analytically and through numerical simulations. Analytical results identify...

International fragmentation, or outsourcing, is often referred to as a distinctly novel feature in today's global economy. First observed in the US-Mexican context, the phenomenon is increasingly catching policy makers' attention also in Europe. As barriers between east and west are...

A distinctive feature of the present wave of economic globalization is that the principle of world-wide arbitrage is increasingly applied to individual components of value added chains, rather than final goods. The result is a phenomenon called outsourcing, or international fragmentation....

Import competition from China is pervasive in the sense that for many good categories, the competitive environment that US firms face in these markets is strongly driven by the prices of Chinese imports, and so is their pricing decision. This paper quantifies the effect of the...

Economic globalization causes an increasing international fragmentation (disintegration) of value-added-chains, whereby firms outsource components of production to foreign markets. There is a high level of concern about unwelcome distributional effects. This paper provides a theoretical...

I develop a generalized factor price frontier which incorporates endogenous adjustment of international fragmentation in multistage production, allowing for a continuum of stages. This allows us to address fragmentation, not only as an exogenous event, but also as an integral part of endogenous...

This paper suggests spatial models as an alternative to the Armington approach to model bilateral trade. While the use of spatial models has been accepted for decades, they are rarely chosen for such analyses. However, problems inherent in the application of the Armington approach can be...

How does intranational factor mobility shape the welfare effects of a trade shock? I provide evidence that during WWI, a demand shock emanated from belligerent countries and affected neutral Spain. Within Spain, labor predominantly reallocated locally, while the most affected provinces...
