理悦CEMA·知与行系列研讨会:Distributional robust auction design

发布日期:2023-06-05

主题:Distributional robust auction design

报告人:杨湘黔,湖南大学经济与贸易学院

摘要:A single unit of a good is sold to one of a group risk-neutral bidders whose privately-known values are drawn independently from an identical distribution. The seller only has limited information about the value distribution and believes that the value distribution is designed by Nature adversarially to minimize revenue. In addition, the seller knows that bidders play undominated strategies. For the two-bidder case, we construct a strong maxmin solution, consisting of a mechanism, a value distribution, and an equilibrium in undominated strategies, such that neither the seller nor Nature can move revenue in their respective preferred directions, even if the deviator can select the new equilibrium in undominated strategies. The mechanism and value distribution solve a family of maxmin mechanism design and minmax information design problems, regardless of how an equilibrium in undominated strategies is selected. The maxmin mechanism is a second-price auction with a random reserve price. For arbitrary number of bidders, a second-price auction with a random reserve price remains a maxmin mechanism among a subclass of dominant-strategy mechanisms.
