There is increasing recognition that the existence of clusters can only be understood when studying their dynamics over time (Audretsch and Feldman 1996; Pouder and St. John 1996; Swann et al. 1998; Maggioni 2002; Brenner 2004; Iammarino and McCann 2006; Menzel and Fornahl 2010; Ter Wal and Boschma 2011). In fact, clusters...

This paper investigates whether related variety, among other types of spatial externalities, affected regional growth in Spain at the NUTS 3 level during the period 1995-2007. We found evidence that related variety matters for growth across regions, especially when measured with the assistance...

We study localization, urbanization, and Jacobs' externality effects on plant survival inSweden (1970-2004). We focus on two questions: (1) do agglomeration externalities changewith the age of plants? (2) using new information about the relatedness among industries,what is the role of...

This paper investigates the extent to which merger and acquisition activity contributed to the spatial clustering of the Dutch banking industry in Amsterdam. This analysis is based on a unique database of all banks in the Netherlands that existed in the period 1850-1993. We found that spatial...

This paper investigates by means of USPTO patent data whether technological relatedness was a crucial driving force behind technological change in 366 U.S. cities from 1981 to 2010. Based on a three-way fixed effects model, we find that the entry probability of a new technology in a city...

Despite theoretical and empirical advances, the proximity framework has remained essentially static in that the given proximity between actors explains the extent to which they interact in knowledge networks and profit from such interactions. We propose a dynamic extension of the proximity...

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...

Who introduces structural change in regional economies: Entrepreneurs or existing firms? And do local or non-local firms and entrepreneurs create most novelty in a region? Using matched employer-employee data for the whole Swedish workforce, we determine how unrelated and therefore how novel the...
