    Persuasion of Interacting Receivers
    (Elsevier, 2026-05-08) Zeng, Yishu
    This paper investigates how to persuade multiple interacting receivers under arbitrary equilibrium selection and when receivers’ preferences may exhibit psychological traits. Our main result characterizes the conditions under which the sender can categorize information using partitions and then disclose partition-related information without altering the equilibrium outcome. This finding broadens the traditional direct approach based on the revelation principle, which categorizes messages solely by equilibrium actions. Consequently, our results support a generalized direct approach, which we apply to study information disclosure in fostering fairness within groups where members may demonstrate altruistic behaviors.

    Derandomization of Persuasion Mechanisms
    (Elsevier, 2023-07-04) Zeng, Yishu
    We consider a setting where one sender can communicate with several privately informed receivers through a persuasion mechanism before the receivers play a game. We show that for any potentially randomized persuasion mechanism, under certain conditions, there is an effectively equivalent deterministic persuasion mechanism, and these two mechanisms have the same set of equilibria. We exhibit the usefulness of our result in an information disclosure application, where our technique helps to derive the optimal persuasion mechanism. Overall, this paper provides a rationale for the fact that persuasion mechanisms are often deterministic in practice.
