Erhao Xie is a Principal Researcher in the Banking and Payments Department (BAP). He develops novel methods to estimate game theoretic models. He also uses these tools to study firm competition in the real world and players’ choices in experiments. He obtained his PhD in Economics from the University of Toronto.

Nonparametric Identification of Incomplete Information Discrete Games with Non-equilibrium BehaviorsThis paper jointly relaxes two assumptions in the literature that estimates games. These two assumptions are the parametric restriction on the model primitives and the restriction of equilibrium behaviors. Without imposing the above two assumptions, this paper identifies the primitives of the game.
Inference in Games Without Nash Equilibrium: An Application to Restaurants’ Competition in Opening HoursThis paper relaxes the Bayesian Nash equilibrium (BNE) assumption commonly imposed in empirical discrete choice games with incomplete information. Instead of assuming that players have unbiased/correct expectations, my model treats a player’s belief about the behavior of other players as an unrestricted unknown function. I study the joint identification of belief and payoff functions.
