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...

Firms’ embeddedness into knowledge networks has received much attention in the literature. However, little is known about the composition of firms’ ego-networks with respect to different types of proximities. Based on survey data of 295 firms in eight European regions, we show that the...

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...

Concepts like regional innovation systems, innovative milieu, and learning regions emphasize the positive contribution of intra-regional cooperation to firmsÕ innovation performance. Despite substantial numbers of case studies, the quantitative empirical evidence for this claim is thin. Using...

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 analyze the emergence and spatial evolution of the German laser systems industry. Regional knowledge in the related field of laser sources, as well as the presence of universities with physics or engineering departments, is conducive to the emergence of laser systems suppliers. The regional...

Over the past two decades, the notion of ÔemergenceÕ has attracted increasing attention and controversy across the social sciences, as par of a growing interest in the applicability of complexity theory to socio-economic-political systems. Within this context, as economic geographers, our...

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...
