We analyze more than 70 million scientific articles to characterize the gender dynamics of commercializing science. The 15-25% gender gap we report is explained neither by the quality of the science nor its ex-ante commercial potential, and is widest among papers with female last authors (i.e., lab heads) when publishing high-quality science. We verify this in a subset of approximately 30,000 “twin” discoveries, for which papers we hand-code the gender of every PI. Results hold whether we define twins via adjacent co-citation or identical biological sequence and structure.

What drives this gap? Prior literature pointed to supply-side factors including reluctance on the part of women to patent or otherwise engage in commercial activity, but we cannot recover evidence for these. Rather, demand-side factors appear to play a key role. First, no gender gap is apparent when women self-commercialize their own discoveries instead of cooperating with existing firms. Second, the gender gap is larger at firms with a higher percentage of male inventors. Third, an increase in accessibility of scientific articles during the Obama administration does not close but rather widens the gender gap. Fourth, consistent with bias we find that discoveries by women that are cooperatively commercialized are of greater value, both using a crude proxy for “marginal” discoveries as well as when instrumenting for the likelihood of cooperative commercialization.
