His research focuses on developing new empirical structural models and estimation methods to understand the forward-looking, strategic, learning, state-dependent, and boundedly rational behavior of consumers and firms under complex environments (including rational inattention and exploration–exploitation problems). He has applied these techniques to study the demand for prescription drugs and nursing homes, new technology adoption decisions, choice of payment methods, information spillovers, late-mover advantages, firm adaptation to concept drift, video game demand, consumer stockpiling, online support groups, and integrated marketing communications. His latest research investigates how information friction affects critical decisions, such as consumer search behavior in complex settings and the mechanisms through which AI systems may amplify misinformation.
