In a recent paper, we analyzed the self-assembly of a complex cooperation network. The network was shown to approach a state, where every agent invests the same amount of resources. Nevertheless, highly-connected agents arise that extract extra-ordinarily high payoffs while contributing comparably little to any of their cooperations. Here, we investigate a variant of the model, in which highly-connected agents have access to additional resources. We study analytically and numerically whether these resources are invested in existing collaborations, leading to a fairer load distribution, or in establishing new collaborations, leading to an even less fair distribution of loads and payoffs.
