我们分析了社交网络中伙伴关系的形成。玩家在随机的时间需要帮助,并要求他们在网络中的邻居形成排他性的长期合作伙伴关系,以保证互惠互利。拒绝提供帮助会导致自动删除基础链接。只有当玩家面临最终被孤立的风险时,他们才同意在合作伙伴关系中提供第一个帮助。在均衡中,对于实现每一个最大匹配至关重要的参与者可以避免这种风险,并且比不重要的参与者享有更高的收益。虽然寻找伙伴的工作是分散进行的,并反映了当地的伙伴关系机会,但关键行为者的力量推动了每个网络有效地建立伙伴关系。平衡行为由底层网络的Gallai-Edmonds分解中的节点分类确定。
We analyze the formation of partnerships in social networks. Players need favors at random times and ask their neighbors in the network to form exclusive long‐term partnerships that guarantee reciprocal favor exchange. Refusing to provide a favor results in the automatic removal of the underlying link. Players agree to provide the first favor in a partnership only if they otherwise face the risk of eventual isolation. In equilibrium, players essential for realizing every maximum matching can avoid this risk and enjoy higher payoffs than inessential players. Although the search for partners is decentralized and reflects local partnership opportunities, the strength of essential players drives efficient partnership formation in every network. Equilibrium behavior is determined by the classification of nodes in the Gallai–Edmonds decomposition of the underlying network.
