Knowledge networks are important to understand learning in industry clusters but surprisingly little is known about what drives the formation, persistence and dissolution of ties. Applying stochastic actor-oriented models on longitudinal relational data from a mature cluster in a medium-tech...

This paper investigates the embeddedness of European regions in different types of inter-regional knowledge networks, namely project based R&D collaborations within the EU Framework Programmes (FPs), co-patent networks and co-publication networks. Embeddedness refers to the network positioning...

This paper investigates the embeddedness of European regions in different types of inter-regional knowledge networks, namely project based R and D collaborations within the EU Framework Programmes (FPs), co-patent networks and co-publication networks. Embeddedness refers to the network...

The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidized...

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...

This paper empirically explores relations between network positions in knowledge networks andtrust. In social network theory the closure argument and the gossip argument describe thisrelation. These two arguments do not distinguish between different dimensions of trust. In thispaper we estimate...
