Scientific rewards for biomedical specialization are large and persistent

Gaétan Jean A de Rassenfosse, Kyle William Higham, Orion B Penner

Background While specialization plays an essential role in how scientific research is pursued, we understand little about its effects on a researcher's impact and career. In particular, the extent to which one specializes within their chosen fields likely has complex relationships with productivity, career stage, and eventual impact. Here, we develop a novel and fine-grained approach for measuring a researcher's level of specialization at each point in their career and apply it to the publication data of almost 30,000 established biomedical researchers to measure the effect that specialization has on the impact of a researcher's publications. Results Using a within-researcher, panel-based econometric framework, we arrive at several important results. First, there are significant scientific rewards for specialization-25% more citations per standard deviation increase in specialization. Second, these benefits are much higher early in a researcher's career-as large as 75% per standard deviation increase in specialization. Third, rewards are higher for researchers who publish few papers relative to their peers. Finally, we find that, all else equal, researchers who make large changes in their research direction see generally increased impact. Conclusions The extent to which one specializes, particularly at the early stages of a biomedical research career, appears to play a significant role in determining the citation-based impact of their publications. When this measure of impact is, implicitly or explicitly, an input into decision-making processes within the scientific system (for example, for job opportunities, promotions, or invited talks), these findings lead to some important implications for the system-level organization of scientific research and the incentives that exist therein. We propose several mechanisms within modern scientific systems that likely lead to the scientific rewards we observe and discuss them within the broader context of reward structures in biomedicine and science more generally.

Technology Protectionism and the Patent System: Evidence from China

Gaétan Jean A de Rassenfosse, Emilio Raiteri

Governments have strong incentives to allow their inventors to free ride on foreign technologies. They can achieve this result by discriminating against foreigners in the patent system-by refusing to grant foreigners a patent for their inventions. International patent law treaties forbid this practice, which may lower the global innovation incentives and may hurt international trade. Using data on half a million inventions submitted to the Chinese patent office, we find robust evidence of anti-foreign bias in the issuance of patents in 'strategic' technology areas. Foreigners are about fifty per cent more likely to be refused a strategic patent than locals.

Modern patent systems are slow, inefficient, expensive, and may result in outcomes that actively harm technological progress. This paper proposes a substantive re-think of these systems and lays a foundation upon which practical solutions can be built. Many solutions proposed in the past, such as prior-art bounties, outsourced examination, and dynamic fee setting, have gone unheeded due to the cost of administering them and the rigidity of the patent system. We explore how distributed ledger technologies (DLTs) enable these major changes by altering the way stakeholders are able to interact with the patent records system. We find that transitioning to a DLT-based patent records system can enable many previously suggested improvements to current patent systems in a flexible, scalable, and transparent manner. The case for such a transition is strengthened when jointly considering the complex but common roots of problems facing modern patent systems, rather than a balkanised set of technical solutions to address each issue independently. Noting that a DLT-based system is not a panacea, we also provide comment on the political, legal, and organisational challenges that must be overcome for such changes to be implemented at scale.
