From a macro perspective, inventor networks are characterized by rather stable structures. However, the high levels of fluidity of inventors and their ties found in reality contradicts this macro pattern. In order to explain these contradicting patterns, we zoom in on the intermediate group...

From a macro perspective, inventor networks tend to generate remarkably stable structures over time. At the same time, we observe highly dynamic processes at the micro level, in terms of inventor entries and exits as well as formations and terminations of collaborative relationships between...

This paper reviews the empirical evidence concerning the regional emergence of innovative new businesses. It is argued that analyses using aggregate data that focus on the regional level and do not account for career patterns of innovative founders are of limited value in guiding policy that is...

We analyze the spatial diffusion of laser-technology in Germany during the early phase of development, between 1960 and 2005. Research in this new technological field began in a few larger centers and then spread to other regions. In the early years, a large firm of the electronics industry...
