Structural Inequality in Collaboration Networks

Abstract

Abstract Recent models of scientific collaboration show that minorities can end up at a disadvantage in bargaining scenarios. However, these models presuppose the existence of social categories. Here, we present a model of scientific collaboration in which inequality arises in the absence of social categories. We assume that all agents are identical except for the position that they occupy in the collaboration network. We show that inequality arises in the absence of social categories. We also show that this is due to the structure of the collaboration network and that similar patterns arise in two real-world collaboration networks.
