This paper investigates the impact of regional sectoral diversity on regional employment growth in Italy over the period 1991-2001. Assuming that externalities may be stronger between industries selling similar products or sharing the same skills and technology (i.e. related industries), we...

This paper makes an attempt to estimate the impact of regional variety and trade linkages on regional economic growth by means of export and import data by Italian province (NUTS 3) and sector (3-digit) for the period 1995-2003. Our results show strong evidence of related variety contributing to...

This paper analyzes the effects of the evolution of knowledge base in the manufacturing sectors on regional productivity growth. Knowledge is viewed as a heterogeneous asset, and an evolutionary perspective is adopted. The results of the empirical estimations corroborate the hypothesis that...

In this paper we contribute to the longstanding discussion on the role of knowledge to economic growth in a spatial context. We observe that in adopting the European policy strategy towards a competitive knowledge economy, The Netherlands is – as most European countries - mainly oriented...

This paper offers an evaluation of the output contribution of infrastructure. Drawing from a large data set of infrastructure stocks covering 88 countries and spanning the years 1960-2000, and using a panel time-series approach, the paper estimates a long-run aggregate production function...

This paper summarizes the theoretical arguments from evolutionary theory and ecological economics to put the trade-off between regional economic diversity and regional economic growth on stronger theoretical foundations. Hypotheses are tested using an empirical model that links regional economic...

Related variety is important to regional growth because it induces knowledge transfer between complementary sectors at the regional level. This is accomplished through three mechanisms: spinoff dynamics, labor mobility and network formation. They transfer knowledge across related sectors, which...

One of the most striking features of the world economy is that wealthy countries are clustered together. This paper theoretically and empirically explains a mechanism for this clustering by extending the Acemoglu and Ventura model so that it takes real geography into account. Countries close to...
