Partial Identification in Entry Games (written with Rohit Kumar)

• We provide a method for the estimation and the inference for static entry games with complete information. Because of the presence of multiple equilibria, the identification problem is complicated and in many cases would lead to a loss of point identification. However, because of the boundedness of the missing information (here the selection mechanism in the regions of multiple equilibria), we can prove that the identified set is bounded. Additionally, the identified set may not be convex, but the set of choice probabilities, implied by the model, corresponding to each parameter in the identified set is convex. We use this convexity to provide a sharp charactrization of the identified set using support functions. Our framework allows for general forms of heterogeneity without making equilibrium selection assumptions.
