Infectious Diseases and Conventional Discrimination

Abstract

This study examines the formation of conventional discrimination against patients with infections. In the model, one expert, Doctor, receives a signal and recommends to either "exclude'' or "accommodate'' patients, and the individuals decide to "evade'' or "accept'' patients in a coordination game with two strict Nash equilibria. An equilibrium concept E-BRD is defined utilizing best response dynamics. The combination of Doctor's recommendation and the dynamic process gives rise to the unique selection of Pareto dominant equilibrium in expectation; however, discrimination arises ex post given Doctor's recommendation of "exclude.''
