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...

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...

Services sectors' agglomeration in the European Union, its development over time, its driving factors and dynamic tendencies will be empirically investigated in this study. Locational gini coefficients are computed taking EU-KLEMS data for 14 European countries covering 22 services sectors over...

This paper provides empirical evidence on the relationship between exports, and in particular export diversity, and regional growth in a developing country context. Using export data for 19 sectors from 354 subnational (magisterial) districts of South Africa, we construct various measures of...

The paper studies the impact of migration policy liberalisation on international labour migration in the enlarged EU in a structural NEG approach. The liberalisation of migration policy would induce additional 1.80 - 2.98 percent of the total EU workforce to change their country of location,...

In this paper the authors develop an innovative 21 sector computable general equilibrium model of Armenia to assess the impact on Armenia of a Deep and Comprehensive Free Trade Agreement (DCFTA) with the EU, as well as further regional or multilateral trade policy commitments. The authors find...

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...
