【摘要】We consider a model of Bayesian persuasion with spillovers. A sender produces information to persuade a receiver to take an action with external effects. We consider how government interventions, including corrective taxes and subsidies, affect social welfare. In addition to internalizing externalities, government interventions affect social welfare through an informational channel. Subsidies to the sender's preferred action incentivize the sender to produce less information, but taxes on the sender's preferred action incentivize the sender to produce more information. Because of such an informational effect, the optimal corrective subsidies and taxes may be different from the Pigouvian level. In some cases, social welfare is maximized with no government intervention.
