We compute the Bayesian- Nash equilibrium of both games, the ex-ante expected profits and the ex-post profits of each firm. We see that, in the price competition, even though only one firm produces in equilibrium, all firms have a positive ex-ante expected profit.engIndustrial organizationGame theoryOligopoly modelsUncertaintyconference object10.1063/1.3515587
