Die ökonomischen Implikationen einer verstärkten Migration deutscher Unternehmen nach Osteuropa und Asien werden derzeit intensiv diskutiert. Wichtige wirtschaftliche Akteure sind KMU des verarbeitenden Gewerbes, die zum einen Elemente komplexer Wertschöpfungsketten bilden, zum anderen...

This paper discusses the interdependencies that exist between vertically-linked industries in the (Spence-)Dixit-Stiglitz model of monopolistic competition. The main objective is to develop a concept for quantifying the magnitude of sectoral coherence in models of the New Economic Geography. It...

Die Biotechnologie, identifiziert als eine der strategischen Zukunftstechnologien, ist gekennzeichnet durch eine hohe Forschungsintensität mit breiten Anwendungsfeldern. Nach einer seit 2001 andauernden Konsolidierungsphase steht die Branche gegenwärtig vor neuen Herausforderungen: der...

This paper discusses a model of the New Economic Geography, in which the seminal core-periphery model of Krugman (1991) is extended by endogenous research activities. Beyond the common anonymous consideration of R&D expenditures within fixed costs, this model introduces vertical product...

This paper picks up the seminal model of Venables (1996) and provides a quantifying concept for the sectoral coherence in vertical-linkage models of the New Economic Geography. Based upon an alternative approach to solve the model and to determine critical trade cost values, this paper focuses...

This Paper takes a broader look at how vertical linkages can trigger the spatial agglomeration of economic activity in a ‘new economic geography’ (NEG) set-up. First, it formally establishes the key positive features of a wide class of vertical-linkage models without resorting to numerical...
