论文摘要
在这项工作中，我们提出了一个战略网络形成模型，可预测多组结构的出现。个人决定根据这些联系带来的利益和成本来形成或删除链接；我们专注于链接形成的双边同意。外源系统指定了两组之间出现的协调问题的频率。我们对解决协调问题的结构感兴趣，尤其是通过桥接，冗余和共同成员互连链接的组结构。我们表征了某些结构稳定并研究其效率以及形成动力学收敛的条件。
In this work we present a strategic network formation model predicting the emergence of multigroup structures. Individuals decide to form or remove links based on the benefits and costs those connections carry; we focus on bilateral consent for link formation. An exogenous system specifies the frequency of coordination issues arising among the groups. We are interested in structures that arise to resolve coordination issues and, specifically, structures in which groups are linked through bridging, redundant, and co-membership interconnections. We characterize the conditions under which certain structures are stable and study their efficiency as well as the convergence of formation dynamics.
