Competing Persuaders in Zero-Sum Games

Understand

We study Bayesian Persuasion with multiple senders who have access to conditionally independent experiments (and possibly others).

• Senders have zero-sum preferences over information revealed.
• We characterize when any set of states can be pooled in equilibrium and when all equilibria are fully revealing.
• The state is fully revealed in every equilibrium if and only if sender utility functions are `globally nonlinear'.
