In this paper, we study the formation of network ties between firms along the life cycle of a creative industry. We focus on three drivers of network formation: i) network endogeneity which stresses a path-dependent change originating from previous network structures, ii) five forms of proximity...

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...

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...

There is consensus among scholars and policy makers that knowledge is one of the key drivers of long-run economic growth. It is also clear from the literature that not all knowledge has the same value. However, too often in economic geography and cognate fields we have been obsessed with...

Although informal knowledge networks have often been regarded as a key ingredient behind the success of industrial clusters, the forces that shape their structure and dynamics remain largely unknown. Drawing on recent network dynamic models, we analyze the evolution of business and technical...

The importance of network structures for the transmission of knowledge and the diffusion of technological change has been emphasized in economic geography. Since network structures drive the innovative and economic performance of actors in regional contexts, it is crucial to explain how networks...

This paper investigates the impact of scientific relatedness on knowledge dynamics in biotech at the city level during the period 1989-2008. We assess the extent to which the emergence of new research topics and the disappearance of existing topics in cities are dependent on their degree of...

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...

Increasing attention had been given recently to understand how networks affect organizational performance in innovation studies. Surprisingly, underlying mechanisms of their evolution have been more neglected, and still remain unclear. This lack of interest is denounced today by recent papers...
