Title : The Two Faces of Open Innovation: NetworkExternalities and Learning

Author(s) : Muge Ozman

Abstract : In this paper I differentiate between two types of benefits of open innova- tion. Network externalities e¤ect happens when open innovation increases the participation of one group of users which increases the value of adoption for another group of users. Learning e¤ect happens when economic actors increase their knowledge through access to external sources of knowledge. I investigate how each effect can be dominant depending on nature of products, by drawing upon previous research in product modularity. In addition I discuss the fac- tors which will strengthen or weaken the e¤ects of each dimension. The main variables which influence learning are, tacitness of knowledge, technological op- portunities, appropriability of knowledge and turbulence. Network externalities e¤ect can be strengthened by increased user innovation.
