Abstract: In a private private information structure, agents' signals contain no information about the signals of their peers. We study how informative such structures can be and characterize those that are Pareto optimal, in the sense that it is impossible to give more information to any agent without violating privacy. In our main application, we show how to optimally disclose information about an unknown state under the constraint of not revealing information about a correlated variable.
