利用面板数据识别同伴效应

Identification of Peer Effects using Panel Data

Marisa Miraldo, Carol Propper, Christiern Rose

摘要:

我们提供了新的识别结果的面板数据模型与同行的影响,通过未观察到的个人异质性。研究结果适用于一般的网络结构,管理同行的相互作用,并允许相关的影响。识别取决于一个有条件的平均限制,需要随着时间的推移,群体之间的个人外源流动性。我们将我们的方法应用于外科医生医院年数据,以研究癌症锁孔手术的接受情况,发现在同一医院执业的其他外科医生的平均个体异质性的积极影响

英文摘要:

We provide new identification results for panel data models with peer effects operating through unobserved individual heterogeneity. The results apply for general network structures governing peer interactions and allow for correlated effects. Identification hinges on a conditional mean restriction requiring exogenous mobility of individuals between groups over time. We apply our method to surgeon-hospital-year data to study take-up of keyhole surgery for cancer, finding a positive effect of the average individual heterogeneity of other surgeons practicing in the same hospital
