Abstract

We analyse how privacy regulations affect information transmission when a platform observes a sensitive and a nonsensitive signal. If privacy is sufficiently important, restrictions that prohibit conditioning on the sensitive signal or require sufficient statistics can eliminate information transmission. When the platform must elicit the sensitive signal from a privacy-concerned sender, the optimal policy endogenously satisfies one or the other requirement depending on parameters.
