Interactive Information Design

We study the interaction between multiple information designers who try to influence behavior of a set agents. When each designer can choose policies from compact statistical experiments with countable support, such games always admit subgame-perfect equilibria. produce public information, every equilibrium simple game in which messages coincides states is robust sense that it an larger and possibly infinite uncountable message sets. The converse true for class Markovian equilibria only. their own corporation agents, pure-strategy exist are characterized via auxiliary normal-form strategies outcomes induced by Bayes correlated her corporation.
