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 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...
