This paper investigates the determinants of co-inventor tie formation using micro-data on genomic patents from 1990 to 2006 in France. We consider in a single analysis the relational and proximity perspectives that are usually treated separately. In order to do so, we analyse the determinants of...

Despite the diffusion of communication tools and boundary spanning technologies, knowledge flows in innovation processes retain a distinct localized nature in many industries and geographical clusters emerge as critical areas to foster technological diffusion. In this paper we focus on the role...

Markets for knowledge are increasingly important to innovation, competitive advantage, and economic growth. This paper examines five distinct markets through which knowledge can be exchanged: the market for codified knowledge (licensing), the market for tacit knowledge (alliances), the market...
