A. Work Performed
Data Collection and Database Construction
We constructed an original dataset named RETE (Repertorium Eruditorum Totius Europae), covering over 83,000 academic scholars active between 1000 and 1800. The scholars were identified from 669 published historical sources, including membership lists from more than 350 European universities and academies. Unlike previous studies focusing on a handful of famous scientists, we include both prominent and lesser-known individuals based on institutional affiliations, not retrospective fame.
Each scholar’s career has been traced geographically and temporally, providing detailed data on institutional affiliations, fields of expertise, and in many cases, their publications as catalogued in modern library holdings.
Historical Reconstruction of Institutions
We systematically compared European universities and academies with similar institutions across the world (e.g. madrasas, Confucian academies, Nalanda monastery). This comparative analysis highlighted that only in Europe did universities develop as legally autonomous corporate entities, which we argue was a crucial enabler of academic freedom, mobility, and intellectual persistence.
Development of Human Capital Measures
A core innovation of the project is a methodology to quantify human capital historically. In the absence of earnings data, we constructed a human capital index based primarily on scholarly output, using publication presence in library databases (VIAF). Though imperfect, this approach allows us to track and compare the evolution of academic quality over time and space.
Conceptual and Theoretical Advances
Drawing on economic theory, we have linked academic meritocracy, mobility, and institutional autonomy with broader developmental outcomes. For instance, we investigate how factors like censorship, religious conflict, and nepotism affected knowledge production. We also explore how universities contributed to the emergence of a pan-European academic market, with Latin as a lingua franca and credentials that allowed scholars to teach across institutions (licentia ubique docendi).
B. Main Results Achieved
1. Europe’s unique institutional design—specifically, the legal autonomy of universities and academies—played a foundational role in creating resilient, self-governing knowledge institutions. These characteristics contrast with institutions elsewhere, which lacked legal personhood and thus remained more fragile or state-dependent.
2. Merit-based recruitment and scholarly mobility were essential features of the European academic system. We observe that highly productive scholars were also highly mobile, contributing to knowledge diffusion and cross-pollination of ideas across regions.
3. Despite occasional ideological interference, notably during religious conflicts and censorship episodes (e.g. the Index of Prohibited Books), the academic system overall facilitated the emergence and diffusion of scientific knowledge.
4. Our data show that upper-tail human capital—i.e. the presence of highly productive individuals in science and medicine—was strongly correlated with urban growth and development, suggesting that premodern academia had tangible economic effects.
5. Finally, preliminary network analyses of academic affiliations confirm that the Protestant Reformation created a significant structural break in European academic networks, reducing mobility between Protestant and Catholic institutions. Nonetheless, science continued to develop robustly in both domains, albeit via different institutional pathways.
