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 study investigates the relationship between labour market externalities and regional growth based on real labour flows. In particular, we test for the importance of labour mobility across so-called skill-related industries. We make use of a sophisticated indicator that measures the degree...

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...

We study the resilience of cities by analyzing their relative capacity to sustain the production of technological knowledge in the face of adverse events. Using patent applications in 366 Metropolitan Statistical Areas in the United States from 1975 to 2002, we analyze the vulnerability and...

Klepper’s theory of industry clustering based on organizational reproduction and inheritance through spinoffs challenged the Marshallian view on industry clustering. The paper provides an assessment of Klepper’s theoretical and empirical work on industry clustering. We explore how ‘new’...

The development of new industries demands access to local capabilities. Little attention has yet been paid to the role of spillovers from neighbor regions for industrial diversification, nor has the role of network linkages between neighbor regions been investigated. As the spread of...

This paper investigates the impact of related variety on regional employment growth in Finland between 1993 and 2006 by means of a dynamic panel regression model. We find that related variety in general has no impact on growth. Instead, after separating related variety among low-and-medium tech...

How do regions diversify over time? Inspired by recent studies, we argue that regions diversify into industries that make use of capabilities in which regions are specialized. As the spread of capabilities occurs through mechanisms that have a strong regional bias, we expect that capabilities...

In this paper, we analyze the geography of knowledge spillovers in biotech by investigating the way in which knowledge ties are organized. Following a relational account on knowledge spillovers, we depict knowledge networks as complex evolving structures that build on pre-existing knowledge and...
