Are mobile researchers more productive and cited than non-mobile researchers? A large-scale study of Norwegian scientists19 sep 2013
The scientific performance of mobile and non-mobile researchers is analysed using publication and citation indicators in a study of more than 11,000 Norwegian university researchers. Two types of mobility are investigated: change of workplace during the scientific career and mobility from an academic institution granting the highest degree to another work place for the scientific career. The study shows that mobile researchers tend to have slightly higher publication and citation rates than other researchers, but the results are not unambiguous. Regression analyses where demographic characteristics of the researchers were accounted for removed most of the independent effect that mobility may have on publication and citation measures. There is currently a strong science policy focus on the beneficence of research mobility. However, this study indicates that mobility has marginal effects on research performance measured bibliometrically.
