The Value of Public Information in Monopoly
证明，向单一买家销售的非线性定价垄断者，总是倾向于承诺公开披露与买家估值相关的信息，即使买家价值影响卖家的机会成本时也成立。
The logic of the linkage principle of Milgrom and Weber (1982) extends to price discrimination. A non-linear pricing monopolist who sells to a single buyer always prefers to commit to publicly reveal information affiliated to the valuation of the buyer. This is also valid when the value of the buyer affects the opportunity cost of the seller.
