Die wichtigste Frage der Raumwirtschaftstheorie lautet: Welches sind die Ursachen für die Entstehung, den Bestand und die Wandlungen räumlicher Wirtschaftsstrukturen? Zu den markantesten Strukturen gehören zweifellos Agglomerationen, die nicht auf natürliche Ursachen zurückgeführt werden...

In standard models of New Economic Geography the overall regional price index in the centre is lower than in the periphery, because trade in manufacturing imposes transportation costs whereas trade in agriculture is assumed to be costless. Since real world observations suggest higher overall...

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...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

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...
