演講摘要 : A data seller offers a dynamic payment schedule for a sequence of experiments to a privately informed buyer. Different buyer types face different expected costs for the same payment schedule because of their different beliefs. This payment gap can be optimized to reduce information rent. Dynamic mechanisms can strictly increase seller revenue compared to the optimal static mechanism, and in some environments can even extract full surplus. We obtain a full characterization of optimal dynamic mechanisms, which can take the simple form of one binary experiment at each stage. Payments are back-loaded, and experiments become progressively more informative over stages.
