Before revision:  By leveraging on the notion of one-player Bayesian Correlated Equilibrium in Bergemann and Morris (  2016) , we provide a tractable characterisation of the sharp identified set and discuss inference under minimal assumptions on the amount of information processed by the decision maker and under no assumptions on the rule with which the decision maker resolves ties.
