Abstract: Mobility of researchers is a key driver of knowledge diffusion, innovation, and international collaboration. While prior research highlights the role of networks in shaping migration flows, the extent to which personal and institutional ties influence the direction of scientific mobility remains unclear. This study leverages large-scale digital trace data from Scopus, capturing complete mobility trajectories, co-authorship networks, and collaboration histories of 172,000 authors. Using multinomial logistic regressions and discrete choice modelling, we systematically assess the effects of first- and second-order co-authorship ties and institutional linkages on scholars’ mobility outcomes, focusing on their first career move. Our findings demonstrate that not only first-, but also second-order co-authorship ties — connections to a scholar’s collaborators’ collaborators — are a strong predictor for the direction of a move. Scholars with extensive individual professional networks, as well as those migrating abroad, are more likely to move along individual ties. In contrast, those from prestigious institutions, as well as those moving nationally, tend to follow institutional routes more often. Discrete choice models further confirm that both individual and institutional ties increase the probability of moving to specific research institutions, with individual connections being more influential than institutional ones. This research provides empirical evidence for the role that individual and institutional connections play in shaping high-skilled labour mobility. Furthermore, it has important implications for migration theory and policy, emphasising the need to support national and international collaborative networks, both individual and institutional, to foster scientific exchange.
