How Gender Differences in Informal Networking Result in Unequal Access to Interorganizational R&D Projects

Women are underrepresented in interorganizational research & development (R&D) projects. This affects the innovativeness of such projects, the representation of female perspectives in the design of innovations and the career opportunities of women. Such projects often emerge from preceding interorganizational R&D projects and are particularly successful when they do so. We argue that instrumental networking in ongoing projects is constitutive for the formation of such follow-up collaborations and, further, that stereotypical gender roles hinder women’s participation in instrumental interactions with their current project partners. Hence, we assume that unequal opportunities to participate in follow-up projects can be attributed to women’s lesser involvement in instrumental networks. Empirically, we test our argument using data on 2746 directed and weighted personal relationships across 24 interorganizational R&D projects. We show that instrumental interactions are crucial for who initiates follow-up projects with which current partner. Furthermore, we can show that the low participation of women in these activities can be better explained by gender roles than by gender homophily. In doing so, we reveal an important cause of women's under-representation in R&D.
