Serbian Academics Abroad

Emigration of Serbian Scientists

The emigration of Serbian scientists translates into a considerable cost for the country. The material cost of education is compounded by the lost opportunity and reduction in scientific productivity. This project investigates how migration and international collaboration impact the productivity of the Serbian academic community.

Data for this project were collected through Microsoft Academic - a web search engine for academic publications. More than 200 million papers were queried to identify Serbian academics. "Serbian academic" is a person who published at least one scientific paper, and who is affiliated with one of the five largest Serbian public universities: University of Belgrade, University of Novi Sad, University of Niš, University of Kragujevac, and State University of Novi Pazar. "Serbian academic migrant" is a person who authored a publication as a member of a Serbian institution but then published another in affiliation with a foreign institution. This method of identification underestimates the number of researchers - it does not identify Serbian students and early-stage researchers who left the country without publishing a paper or Serbian-born researchers who completed their education abroad and were never affiliated with a Serbian university. Nevertheless, the method is effective for estimating migration trends. Finally, a "collaboration" is a co-authorship between a domestic and foreign academic.

Key Findings

We identified a total of 11,372 researchers with Serbian affiliation for the period from 2000 to 2020. Of that number, 977, or 8.6%, were identified as migrants. About 93% of migrants did not publish a paper with a Serbian author after leaving the country, suggesting that communication between a migrant and Serbian scientific community ends once a migrant leaves the country.

We found a statistically significant difference in output between researchers at the Serbian public universities and Serbian academic migrants. On average, a migrant will publish 2.3 papers more per year than their Serbian counterpart. In addition, there is a statistically significant increase in the publishing record of domestic scientists who collaborate with foreign scientists. On average, more collaborative authors publish 1.9 papers per year more than less collaborative authors.

Additionally, there are several concerning trends. First, the number of scientific papers published annually in Serbia has had very modest growth in the last 8 years and has even decreased in 2017 and 2018. Second, the productivity of physics, engineering, and mathematics is continuously declining, which has a negative effect on the young researchers entering the field. Third, year-by-year numbers in some disciplines erratically fluctuate, suggesting a lack of stability and continuity of funding.
