Consider an observed binary regressor D and an unobserved binary variable D*, both of which affect some other variable Y. This paper considers nonparametric identification and estimation of the effect of D on Y , conditioning on D* = 0. For example, suppose Y is a person's wage, the unobserved D...

This paper develops a model that allows for heterogenous contemporaneous peer effects among different types of agents who are endogenously selected into different peer groups. Using our framework, we characterize the reduced-form coefficient in the peer effect literature and show that it is a...

Despite extensive literature on peer effects, the role of peers on personality skill development remains poorly understood. We fill this gap by investigating the effects of having disadvantaged primary school peers, generated by random classroom assignment and parental migration for employment....
