Biography

Prof. Hsieh obtained his Ph.D. degree of Economics from the Ohio State University at 2013 and is currently an Assistant Professor in the Department of Economics at the Chinese University of Hong Kong.  His research interests span over labor economics, health economics, and social networks. In particular, he works on endogenous selection issues inherited in social interaction studies. For example, when studying peer effect on school outcomes such as academic performances or health-related behaviors, e.g., smoking, drinking, etc., based on school friendships, the estimate of peer effect will be upward biased because students self-choose their friends. To correct this bias, he proposes a latent variable approach to control individual unobservables which affect both friendship decisions as well as school outcomes. The simulation and empirical results show that this latent variable approach is effective in removing the bias. Besides, he also studies empirical network formation. He develops an empirical network formation model to accommodate various important features from observed network data, such as homophily in characteristics, behaviors, as well as link dependence. He applies the model to study formation of students' friendship networks and firms' R&D networks.
