A new paper in Higher Education Quarterly by Andrey Lovakov, Maria Yudkevich and Olga Alipova
This paper studies the publication productivity of inbreds and non‐inbreds among Russian academics. The authors did not find any difference in current publication productivity of inbreds and non‐inbreds. However, they found a difference in the cumulative publication productivity: non‐inbreds are being more productive on an individual level throughout their careers.
