We investigate the stability of cooperative relationships between inventors and consequences for the characteristics and patent productivity of the respective regional innovation systems (RIS). The empirical analysis is for nine German regions over a period of 15 years. We find a rather high...

The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...

We investigate the regional emergence of new information technology start-ups in Germany.

Literature suggests that location should matter for R&D activities. However, attempts to empirically detect differences in innovation activity between regions have so far been rather unsuccessful. Using a unique data set which contains comparable information about manufacturing enterprises in...

This paper investigates interregional differences in cooperative behavior of manufacturing establishments in the field of research and development (R&D). The empirical analysis for eleven European regions reveals a number of significant differences between these regions in the propensity to...
