主讲内容:

我们提出了一个新的解决方案概念，涉及到由Chew和Wang（2021年）对Savage（1954年）的商人例子中隐含的知识的肯定原则（STP）的形式化促进的Weak Dominance。这个解决方案的概念介于Weak Dominance和Li（2017）的Obvious Dominance之间，并完善了STP促进的Obvious Strategyproofness（OSP-STP）的机制设计的相应概念。我们进一步研究了OSP-STP的启示原则，以及在此原则下，延迟接受和顶级交易周期机制的实施，以及同步上升组合拍卖。

We propose a new solution concept involving Weak Dominance facilitated by Chew and Wang’s (2021) formalization of the sure-thing principle (STP) with knowledge implicit in Savage’s (1954) businessman example. This solution concept is intermediate between Weak Dominance and Li’s (2017) Obvious Dominance and refines the corresponding concept for mechanism design of a STP-facilitated Obvious Strategyproofness (OSP-STP). We further study the revelation principle for OSP-STP and the implementation, under this principle, of the Deferred Acceptance and Top Trading Cycle mechanisms, along with the Simultaneous Ascending Combinatorial Auction.
