Measuring Homophily in Scientific Collaboration

How to explain the rise of academic collaborations and why academics tend to bridge together have long been subjects of theoretical and empirical interest in social network research. In this paper, we aim to look at the work of academics working in the Institute of Health and Wellbeing (IHW) at the University of Glasgow between 2010 and 2017 and evaluate to what extent academics tended to co-author a paper and apply for funding together. One way to analyse the mechanisms that influence the formation of academic collaborations across scientific disciplines (e.g. Mental Health, Social Science for Health, Health Economics) is to model them through the use of exponential random graph models (ERGM). This article applies an ERG social selection model in order to predict how strongly the affiliation to a specific research group has influenced intra and cross-discipline collaborations among academics working at the Institute. Our results suggest that intradiscipline collaborations are still prevalent and also find that the homophily effect is less strong for crossing disciplinary boundaries research groups. Further theoretical and methodological implications are also discussed.
