This paper analyzes the trade of information between a data buyer and a data seller. The data buyer faces a decision problem under uncertainty and seeks to augment his initial private information with supplemental data. The data seller is uncertain about the willingness-to-pay of the data buyer due to this private information. The data seller optimally oﬀers a menu of (Blackwell) experiments as statistical tests to the data buyer. The seller exploits diﬀerences in the beliefs of the buyer’s types to reduce information rents while limiting the surplus that must be sacriﬁced to provide incentives.
