International Collaboration in Higher Education Research: A Gravity Model Approach

Scientometrics (2021)


Although geographical distance has become less relevant in coauthorship for monodisciplinary fields such as economics, mathematics, and physics, little is known about international collaboration in multidisciplinary fields such as higher education. This paper studies collaboration patterns in higher education research using the Scopus database with the application of the gravity model. The results show that the intensity of collaboration is negatively associated with geographical distance and positively associated with linguistic commonality but these findings differ significantly between various world regions. European scholars appear to give preference to linguistically proximate partners over geographical neighbours. Although English is the lingua franca in science, language is not a significant factor for the formation of collaboration for North American and Asian researchers. These findings have policy implications for fostering multidisciplinary research in international partnerships.

The Effect of the Bologna Reform on the Graduate Labor Market

Under review (2022)

[Slides] [Video]

The Bologna reform is the largest education reform of the 21st century in Europe. In 2011, this reform shortened the duration of undergraduate programs by one year and reduced the content of the curricula in Russia. Using this reform as a natural experiment, I find no adverse effect of a 20% reduction in the length of higher education on employment. The reform has also no negative effects on wages for graduates who worked less during their studies. A possible mechanism of no adverse effects is that students could compensate for the loss of their human capital by investing more time in studying.
