We analyze information and knowledge transfer in a sample of 16 German regional innovation networks with almost 300 firms and research organizations involved. The results indicate that strong ties are more beneficial for the exchange of knowledge and information than weak ties. Moreover, our...

Previous empirical research has established that science appears to stimulate the widespread diffusion of knowledge. The exact mechanism through which science catalyzes knowledge flow, however, remains somewhat ambiguous. This paper investigates whether the observed knowledge diffusion...

We analyze the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. Our central hypothesis states that technologies which become more...

We provide some of the first rigorous evidence on performance spillovers and social network in the workplace. The data we use are rather extraordinary - weekly data for rejection rates (proportion of defective output) for all weavers in a firm during a 12 months (April 2003-March 2004) period,...

Analysing the relationship between firms' openness to external knowledge and their innovation performance is nothing new. What is new is studying how this relationship fares in latecomer economic contexts such as Nigeria, and that is the focus of this paper. Using unique micro-level innovation...

We explore the evolution of the structure and performance of a social network in a population of individuals who search for local optima in diverse and dynamic task environments. Individuals choose whether to innovate or imitate and, in the latter case, from whom to learn. The probabilities of...

This paper adopts sociometric analysis to explore the process of knowledge acquisition and diffusion in clusters of firms. By comparing the knowledge systems of two clusters selected for being at different stages of their development path, this study shows that the knowledge system of the...

The objective of this paper is to analyse the dynamics of networks in which new knowledge emerges and through which it is exchanged. Our conjecture is that the structure of a network cannot be divorced from the dynamics of the knowledge underpinning its activities. In so doing we look beyond...

Dieses Paper fasst die ersten Ergebnisse des Forschungsprojektes Wissenstransfer in Deutsch-Türkischen Innovationsnetzwerke (TGIN) im Kontext der Europäischen Union zusammen. TGIN eröffnet eine neue Perspektive auf die deutsch-türkische Beziehungen, indem es die ökonomischen Win-Win...

This study investigates mechanisms of tie formation in an interorganizational network generated by the mobility of employees between organizations. We analyze a data set that contains information on all organizations in the Stockholm metropolitan area between 1990 and 2003. We show that the...
