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...

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 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...

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...

Economic geography has developed a stronghold analysing how geography impacts innovation. Yet, despite increased interest in networks, a critical assessment of the role of geography in the evolution of networks is still lacking. This paper juxtaposes geographical proximity with the network of...
