摘要本研究考虑一个网络形成模型，其中每一对代理策略性地决定链接状态。我们的模型允许代理商在链接形成的倾向中具有未观察到的组异质性。对于模型估计，我们提出了一个三步最大似然方法，其中潜在的群体结构估计使用二进制分割算法在第二步。作为一个实证说明，我们专注于国际免签旅行的网络数据。研究结果表明，网络形成行为存在显著的战略互补性和一定程度的异质性。
Abstract This study considers a network formation model in which each dyad of agents strategically determines the link status. Our model allows the agents to have unobserved group heterogeneity in the propensity of link formation. For the model estimation, we propose a three-step maximum likelihood method, in which the latent group structure is estimated using the binary segmentation algorithm in the second step. As an empirical illustration, we focus on the network data of international visa-free travels. The results indicate the presence of significant strategic complementarity and a certain level of degree heterogeneity in the network formation behavior.
