扩散拍卖的再分配框架

A Redistribution Framework for Diffusion Auctions

Sizhe Gu, Yao Zhang, Yida Zhao, Dengji Zhao

摘要:

再分配机制设计的目的是在不影响真实性的前提下,将真实拍卖所得的收益重新分配给参与者。我们研究扩散拍卖的再分配机制,这是机制设计的新趋势[19]。扩散拍卖的一个关键特性是激励现有的参与者邀请新的参与者加入拍卖。因此,当我们设计再分配时,我们也需要保持这种激励。传统环境中现有的再分配机制的目标是修改真实机制的支付设计,例如维克瑞拍卖。在本文中,我们不关注一个特定的机制。相反,我们提出了一个一般的框架,重新分配的收入回到所有真实的扩散拍卖出售单一项目。该框架将原真实扩散拍卖视为黑盒,并不影响其真实性。该框架还可以分配回几乎所有的收入。

英文摘要:

Redistribution mechanism design aims to redistribute the revenue collected by a truthful auction back to its participants without affecting the truthfulness. We study redistribution mechanisms for diffusion auctions, which is a new trend in mechanism design [19]. The key property of a diffusion auction is that the existing participants are incentivized to invite new participants to join the auctions. Hence, when we design redistributions, we also need to maintain this incentive. Existing redistribution mechanisms in the traditional setting are targeted at modifying the payment design of a truthful mechanism, such as the Vickrey auction. In this paper, we do not focus on one specific mechanism. Instead, we propose a general framework to redistribute the revenue back for all truthful diffusion auctions for selling a single item. The framework treats the original truthful diffusion auction as a black box, and it does not affect its truthfulness. The framework can also distribute back almost all the revenue.
