论文摘要
本文考虑了在不可转移实用程序（NTU）下的二元网络形成的半参数模型。 NTU经常出现在需要双边同意的现实社会互动中，但本质上会引起加性不可分割性。我们展示了如何使用一种新的方法来消除模型中未观察到的单个异质性，而无需可分离性，我们称之为逻辑差异。关键思想是构建涉及基于多元单调性的未观察到异质性的两个相互排斥限制的交集的事件。我们提供一致的估计器并通过模拟分析其性能，并将我们的方法应用于Nyakatoke风险共享网络。
This paper considers a semiparametric model of dyadic network formation under nontransferable utilities (NTU). NTU arises frequently in real-world social interactions that require bilateral consent, but by its nature induces additive non-separability. We show how unobserved individual heterogeneity in our model can be canceled out without additive separability, using a novel method we call logical differencing. The key idea is to construct events involving the intersection of two mutually exclusive restrictions on the unobserved heterogeneity, based on multivariate monotonicity. We provide a consistent estimator and analyze its performance via simulation, and apply our method to the Nyakatoke risk-sharing networks.
