Science, social networks and spillovers
Author: Sorenson, Olav ; Singh, JasjitINSEAD Area: StrategyIn: Industry and Innovation, vol. 14, no. 2, June 2007 Language: EnglishDescription: p. 219-238.Type of document: INSEAD ArticleNote: Please ask us for this itemAbstract: Although prior empirical research has established that science appears to stimulate the widespread diffusion of knowledge, the exact mechanism through which science catalyzes information flow remains somewhat ambiguous. This paper considers whether the observed knowledge diffusion associated with science-based innovation stems from the norm of openness and incentives for publication, or whether scientists maintain more extensive and dispersed social networks that facilitate the dissemination of tacit knowledge. Our analysis supports the former mechanism: we use patent citation patterns to track the movement of knowledge, and find that science-based innovations diffuse more rapidly and widely, even after controlling for the underlying social networks of researchers as measured using information on prior collaborations. We also find that publication and social networks act as substitutes in the diffusion of knowledge.| Item type | Current location | Call number | Status | Date due | Barcode | Item holds |
