We model the evolution of infrastructure networks as a preferential attachment process. We assume that geographical distance and country borders provide barriers to link formation in infrastructure networks. The model is validated against empirical data on the European Internet infrastructure...

Cluster policies have been recently called into question in the aftermath of several empirical evidences. Disentangling how market and network failures arguments play together in cluster policy design, we look for more robust micro foundations of network structuring in clusters. Our aim is to...

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...

The debate on Russia’s innovation performance has paid little attention to the role of geography. This paper addresses this gap by applying an ‘augmented’ regional knowledge function approach to examine the territorial dynamics of innovation in Russia. The empirical results suggest that...

The paper investigates the diversified patterns of outsourcing in the Lombardy region and relates them to the probability of introducing product and process innovation. Based on a large firm-level survey, we show that outsourcing processes are strongly regionally embedded and that offshoring is...

The paper develops an evolutionary framework of regional resilience with a primary focus on the structural properties of local knowledge networks. After a presentation of the network-based rationales of growth and structuring of clusters, we analyze under which structural conditions a regional...

The economic geography literature assumes that large leading firms (technology gatekeepers)(TGs) with high absorptive capacity and high-intensity R&D expenditures, shape the district learning process. However, there is an absence in the literature of a dynamic analysis of the role of the TG....

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...

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...

What is meant by entrepreneurship, innovation and economic growth is often not clear or very idiosyncratic. This paper starts with a discussion of the nature of entrepreneurship and its relation to innovation. The second section provides an overview of theory and empirical research on the...
