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...

We perform a characterization of Colombia's industrial exports for the 1990-2010 period. We contrast the commonly used classification of exports (traditional vs. nontraditional) to that of Lall's (2000), which is based on the technological component of exports, stressing the advantages of the...

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...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selection into trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting firms takes a gravity form, such that the extensive margin is also affected by...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

How do firms' financial constraints, which restrict their borrowing, dynamically impact exports? This paper finds that after controlling for the endogeneity of financial constraints, constrained firms are less likely to export, and relaxing financial constraints leads to an increase in exports....
