THE VALUE OF PRIVATE INFORMATION IN MONOPOLY*
研究了垄断卖家在何种情况下有动机允许潜在买家获取更多关于自身偏好的私人信息，发现当支付意愿密度对数凹且边际成本凸时，卖家希望付费群体整体知情但个体对自身偏好无知。
We investigate a basic question about a monopoly with incomplete information: when does the seller have an incentive to allow potential buyers to acquire more private information about their tastes for the seller's product? Under plausible conditions such as log‐concave density of willingness‐to‐pay and convex marginal cost, the seller prefers that the paying customers be well informed as a group but be left in the dark regarding their individual tastes.
