Persuading an inattentive and privately informed receiver

This paper studies the persuasion of a receiver who accesses information only if she exerts costly attention effort. A sender designs an experiment to persuade the receiver to take a specific action. The experiment affects the receiver's attention effort, that is, the probability that she updates her beliefs. Persuasion has two margins: an extensive (effort) and an intensive (action). The receiver's utility exhibits a supermodularity property in information and effort. By leveraging this property, we establish an equivalence between experiments and persuasion mechanisms \`a la Kolotilin et al.~(2017). In applications, the sender's optimal strategy involves censoring favorable states.
