In this Appendix, we allow the receiver to make a choice among multiple actions. We characterize the implementable receiver's interim utilities and show that the sender can generally implement a strictly larger set of the receiver's interim utilities by persuasion mechanisms than by experiments. We also formulate the sender's optimization problem and show that the sender can achieve a strictly higher expected utility by persuasion mechanisms than by experiments.
