(A) structural inequality in higher education system: a comparative study on economics and physics department

Abstract

The number of research collaborations has more than tripled over the past 15 years, and this trend is expected to continue as researchers come together to solve global problems. Analyzing the movements of high-skilled labors, such as researchers, is an important topic in political science, research policy. In this thesis, we consider the mobility and collaboration of researchers as an analysis of the complex network on institutional level. We conduct a quantitative study of the hierarchy of educational institutions and their privileges by analyzing the collaboration network of higher education institutions across borders and the professor appointment network together. In particular, we investigated the impact of privileges of prestigious institutions, focusing on economics and physics, on professor appointment networks or collaborative networks through regression and exponential random graph models. Based on these results, we analyzed the differences in network characteristics by department and looked at the characteristics of nodes that cause the network to be created.
