Land use. Labor subject: RS Pharmacy and materia medica description: This paper examines how a radical technological innovation affects alliance formation of firms and subsequent network structures. We use longitudinal data of interfirm R&D collaborations in the biopharmaceutical industry in which a new technological regime is established. Our findings suggest that it requires radical technological change for firms to leave their embedded path of existing alliances and form new alliances with new partners. While new partners are mostly found through the firms’ existing network, we provide some insight into distant link formation with unknown partners, which contributes to our understanding of how ‘small-worlds’ might emerge publisher: Association pour le développement de la recherché en économie et en statistique date: 2007-12 type: Article type: PeerReviewed identifier: Phlippen, Sandra and Riccaboni, Massimo Radical innovation and network evolution.
