I am looking for existing research indicating that in some cases, bridging and/or brokerage may cause economic disadvantages for individuals, particularly when or if there are strong network subgroups which may "penalize" brokers for associating with other groups.I am very familiar with Burt's work on brokerage, but my primary takeaway from it is that occupying brokerage positions is thought to be a source of social capital expected to generate benefits. I am looking for theoretical and/or empirical evidence that suggests the opposite - i.e., people who broker are significantly less productive (economically), particularly when/if there are strong network subgroups that may cause brokers (defined as individuals who bridge these network subgroups) to be socially ostracized for associating with other groups.If anyone can point me in the direction of existing research (in any field) that sheds light on this sort of effect, it would be much appreciated.Thank you in advance for your time,Michele Barnes-MautheMichele Barnes-MautheResearch Assistant, PhD CandidateJoint Institute for Marine and Atmospheric ResearchDepartment of Natural Resources and Environmental ManagementUniversity of Hawaii at ManoaInterested in marine resource management?
