我们开发了一个模型，该模型表明，在纳什均衡，嵌入在网络中的每个人的结果是成比例的，他/她的卡茨-Bonacich中心性措施。这一措施考虑到每个人的直接和间接朋友，但对他/她的远亲的重视程度较低。然后，我们使用非常详细的青少年友谊网络数据集将模型与数据结合起来。我们发现，在控制可观察到的个人特征和不可观察的网络特定因素后，Katz-Bonacich中心性的标准差增加使学生的学校表现增加了7%以上的标准差。
We develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to his/her Katz-Bonacich centrality measure. This measure takes into account both direct and indirect friends of each individual, but puts less weight to his/her distant friends. We then bring the model to the data using a very detailed dataset of adolescent friendship networks. We show that, after controlling for observable individual characteristics and unobservable network specific factors, a standard deviation increase in the Katz-Bonacich centrality increases the pupil school performance by more than 7% of one standard deviation.
