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...

The paper investigates how competition between two multiproduct downstream firms in vertical relationships affects horizontal relationships: competitor collaboration and performance difference. When the upstream market consists of exclusive suppliers, the efficient firm may have incentive for...

The literature on "Innovation Systems" is divided into several directories. Dif- ferences occur through the definition of the system's borders. This paper intro- duces a methodology how to differentiate between regional and technological effects of cooperative innovation activities and analyzes...

In the literature there is a controversy about the relevance of the spatial dimension in innovation collaboration. We examine the link between the spatial composition of group members and group characteristics which are important for performing innovation projects. To this end, we introduce a...

The paper compares academic and corporate patents in Germany to shed light on the geographical distribution of the inventors. The residences of the inventors show different patterns in the two datasets. Furthermore, we analyze the spatial distance between inventors for patents invented in...

Spatial proximity is assumed in the literature to be a prerequisite and trigger for cooperation and, subsequently, innovation. This paper examines conceptually the role of proximity between actors for cooperation activities. Using theories and findings from social psychology and combining them...

This paper explores the drivers of inter-firm R&D collaborations in a particular type of innovation network, the technological districts created in Italy under a specific public policy to promote innovation. The empirical analysis used an original database containing information on research...

The role of geographical proximity in fostering connections and knowledge flows between innovative actors ranks among the most controversial themes in the research of innovation systems, regional networks and new economic geography. While there is ample empirical evidence on the constituent...

This paper studies the impact of collaboration on research output. First, we build a micro-founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...

The authors develop an agent-based model to reproduce the size distribution of R&D alliances of firms. Agents are uniformly selected to initiate an alliance and to invite collaboration partners. These decide about acceptance based on an individual threshold that is compared with the utility...
