社交网络上的组合拍卖元机制

Meta-mechanisms for Combinatorial Auctions over Social Networks

Yuan Fang, Mengxiao Zhang, Jiamou Liu, Bakh Khoussainov

AI总结:

本文提出元机制,将经典拍卖机制统一转换为社交网络环境下的机制并保留关键性质,首次解决单一意向买家与一般单调估值两类网络组合拍卖问题。

摘要:

近年来,已有大量研究致力于为投标人通过社交网络连接的拍卖场景设计机制。与该领域现有研究聚焦于特定拍卖场景(如单物品拍卖和多物品拍卖)不同,本文考虑以下问题:是否有可能设计一种方案,使得给定一个经典拍卖场景及其适配的机制 $\tilde{\mathcal{M}}$,能够在网络环境下生成一个保留 $\tilde{\mathcal{M}}$ 关键性质的机制?为回答这一问题,我们设计了元机制,提供了一种将经典模型中的机制统一转换为网络环境下机制的方法,并证明了我们的元机制能够保留所期望的性质。我们的元机制为网络环境下的组合拍卖场景提供了解决方案:(1)具有单一意向买家的组合拍卖;(2)具有一般单调估值的组合拍卖。据我们所知,这是首个在社交网络上设计组合拍卖的工作。

英文摘要:

Recently there has been a large amount of research designing mechanisms for auction scenarios where the bidders are connected in a social network. Different from the existing studies in this field that focus on specific auction scenarios e.g. single-unit auction and multi-unit auction, this paper considers the following question: is it possible to design a scheme that, given a classical auction scenario and a mechanism $\tilde{\mathcal{M}}$ suited for it, produces a mechanism in the network setting that preserves the key properties of $\tilde{\mathcal{M}}$? To answer this question, we design meta-mechanisms that provide a uniform way of transforming mechanisms from classical models to mechanisms over networks and prove that the desirable properties are preserved by our meta-mechanisms. Our meta-mechanisms provide solutions to combinatorial auction scenarios in the network setting: (1) combinatorial auction with single-minded buyers and (2) combinatorial auction with general monotone valuation. To the best of our knowledge, this is the first work that designs combinatorial auctions over a social network.
