In this paper, I aim to assess the influence of spatial mobility of knowledge workers on the formation of ties of scientific and industrial collaboration across European regions. Co-location has been traditionally invoked to ease formal collaboration between individuals and firms. Tie formation...

What makes special the geography of the clusters of creative industries (CI)? This paper considers the symbolic knowledge-base and the preference for location in urban spaces observed in those clusters. The study avoids classic research designs based on synthetic knowledge bases and...

This study explores the worldwide spatial evolution of scientific knowledge production in biotechnology in the period 1986-2008. We employ new methodology that identifies new key topics in biotech on the basis of frequent use of title worlds in major biotech journals as an indication of new...

This paper provides a theoretical and political critique of how the concept of resilience has been applied to places. It is based upon three main points. First, the ecological concept of resilience is conservative when applied to social relations. Second, resilience is externally-defined by...

We investigate the persistence of levels of self-employment and new business formation in different time periods and under different framework conditions. The analysis shows that high levels of regional self-employment and new business formation tend to be persistent for periods as long as 80...

Although increasing attention is paid to the resilience of regions to economic shocks, theoretical and empirical insights in the determinants of regional resilience are still limited. This paper aims to make a first step in quantifying regional resilience. Using a model, we explore how three...

This paper examines the extent to which the distinct settlement pattern of migrants arriving in the US during the big migration waves of the late 19th and early 20th centuries has left a legacy on the economic development of the counties where they settled and whether this legacy can be traced...

Despite the growing number of studies, still little is known about how network structures and proximity relations between linked actors evolve over time. Arguments are put forward for the existence of co-evolution dynamics between different types of proximity configurations within networks. An...

U.S. patent data and patent citations are used to build a measure of knowledge relatedness between all pairs of 438 major patent classes in the USPTO. The knowledge relatedness measures, constructed as the probability that a patent in class j will cite a patent in class i, form the links of a...

This paper analyzes the emergence of new technology-based sectors at the regional level. We focus on the specific case of nanotechnology as representative of an industry based on a technology still in infancy whose evolution can be reliably traced on the basis of filed patent submissions. We...
