Identification and Estimation of Outcome Response with Heterogeneous Treatment Externalities

Gender and Peer Effects on Performance in Social Networks

“…In particular, peer effects in our Sequential treatments are identified since by construction the reference groups' behavior is predetermined. Peer effects in our simultaneous networks are also identified since we show that our model satisfies Arduini et al (2016)'s conditions for identification under group heterogeneity.…”

“…to allow both the performance and the contextual peers effects to vary across genders. 5 Our model is inspired by Arduini et al (2016).…”

Gender Peer Effects Heterogeneity in Obesity

“…Our approach is related to the one developed in Arduini et al [2016]. In their paper, the authors focus on the identification and estimation of treatment response with heterogeneity using a network model.…”

“…Also, while their estimation approach focuses on a 2SLS method, we provide both 2SLS and GMM estimators, the latter exploiting quadratic moments. Moreover, while Arduini et al [2016] present Monte Carlo simulations of their approach, we provide an empirical application to peer effects heterogeneity in obesity.…”

“…Beside the study by Arduini et al [2016] discussed in the introduction, a growing number of researches have focused on issues raised by heterogeneity in peer effects. Many papers assume that individuals interact in a network composed of groups 10 and analyze the impact of gender proportion on the outcomes of male and female individuals (e.g.…”
