Baruffaldi, Stefano Horst; Byrski, Dennis; Gaessler, Fabian (2020). Fire and Mice: The Effect of Supply Shocks on Basic Science, Academy of Management Proceedings, 2020 (1). DOI

  • We study how a negative supply shock to research-related assets affects the production of scientific knowledge. In particular, we exploit the 1989 Morrell Park fire that destroyed a considerable share of the world's largest mice breeding facility, the Jackson Laboratory, and killed approximately 400,000 mice. This fire led to an unforeseen and substantial supply shortage in mice for the North American biomedical research community, which we can isolate at the strain and scientist level based on proprietary archival data. Using difference-in-differences estimations, we find that the scientific productivity of affected scientists decreases when measured in simple publication counts, but much less so when we adjust for the publications' quality. Moreover, affected researchers are more likely to initiate research that is unrelated to their previous work. This indicates that affected scientists switched research trajectories but maintained their scientific impact. In the aggregate, the temporary supply shortage of particular mice strains led to a permanent decrease in their usage among U.S.\ scientists. These results highlight the important role of supply chains in basic science."

  • The field of antimicrobials is considered to be facing a crisis. Increasing microbial resistance is creating a demand for new drugs, which however is not being matched by privately funded R&D. The reasons for this market failure are of a technical and economic nature. The present article analyzes what changes to IP- based incentives are conceivable in the European Union (EU) in order to address the antimicrobial crisis. Since the assessment of the suitability of the analyzed options depends on interdisciplinary research, this article also proposes a research agenda to be considered for the implementation of public policies in this field.

              • Prior literature has established a link between changes in market size and pharmaceutical innovation; whether a link exists with scientific research remains an open question. If upstream research is not responsive to these changes, the kinds of scientific discoveries that flow into future drug development could be disconnected from downstream demand. We explore this question by exploiting the effects of quasi-experimental variation in market size introduced by Medicare Part D. We find no causal relationship between market size and biomedical research in the decade following the implementation of Medicare Part D. While many factors have been shown to motivate scientists to conduct research, this result suggests that changes in market size provide no such incentive. We do find, however, limited support for a response by corporate scientists conducting applied research. Implications for pharmaceutical innovation policy are discussed.
