Information Suppression in Bayesian Persuasion

A sender is seeking approval from the receiver(s). He conducts experiments to two receivers with identical preferences sequentially. The first receiver can approve, reject, or delay the decision to the next receiver while the second receiver must approve or reject. Upon delay, the first receiver can communicate his information to the second receiver or hide it. This chance of information suppression creates the incentive to delay when the second receiver is naive -- interpreting the absence of communication as the absence of information. Facing this incentive, the sender discloses more information to the first receiver to induce immediate action when delay is very costly, and discloses less information so that the first receiver may delay when delay is not so costly. And in the former possibility, the first receiver is better off than the static game and has a positive value of persuasion
