Despite the advantages of occupying brokerage positions in a collaboration network, such positions are considered to be ephemeral and unstable. Drawing on resource-dependence theory, I argue that the maintenance of a brokerage position is enhanced by the dependence asymmetry between the broker and the brokered alters. I test this idea on collaboration networks of creative artists in writing new and original songs for the Korean popular music (K-pop) industry where those who perform multiple roles possess more resources to share with others. From analyzing the drivers of bridge maintenance and of network closure, I find that brokerage positions occupied by multirole actors are more likely to be maintained, especially when brokered alters are single-role actors. In additional analyses, I find further support that the dependence asymmetry between the broker and brokered alters is responsible for the maintenance of brokerage positions.
