具有不可转移效用的双边匹配市场的竞争均衡

Competitive Equilibria in Two Sided Matching Markets with Non-transferable Utilities

Saeed Alaei, Kamal Jain, Azarakhsh Malekian

摘要:

我们考虑由具有不可转移效用的代理人组成的双边匹配市场;来自相对侧的代理人形成匹配对(例如,买方-卖方)并协商他们的数学条款,其中可能包括货币转移。竞争均衡是这个博弈的核心要素。我们提出了第一个组合的竞争均衡的特点,涉及到每个代理商在均衡的效用,其他代理商在一个严格的较小的市场,不包括该代理商的均衡效用,从而自动提供了一个建设性的证明竞争均衡在这样的市场中的存在。我们的特征还产生了一个组strategypproof机制分配不可分割的商品与非准线性公用事业,非常类似的维克雷克拉克格罗夫斯(VCG)机制的单位需求的买家。作为一个直接的应用程序,我们提出了一个组策略的福利最大化机制的广告拍卖,而不需要通常的假设,搜索引擎和广告商有一致的估计的点击率。

英文摘要:

We consider two sided matching markets consisting of agents with non-transferable utilities; agents from the opposite sides form matching pairs (e.g., buyers-sellers) and negotiate the terms of their math which may include a monetary transfer. Competitive equilibria are the elements of the core of this game. We present the first combinatorial characterization of competitive equilibria that relates the utility of each agent at equilibrium to the equilibrium utilities of other agents in a strictly smaller market excluding that agent; thus automatically providing a constructive proof of existence of competitive equilibria in such markets. Our characterization also yields a group strategyproof mechanism for allocating indivisible goods to unit demand buyers with non-quasilinear utilities that highly resembles the Vickrey Clarke Groves (VCG) mechanism. As a direct application of this, we present a group strategyproof welfare maximizing mechanism for Ad-Auctions without requiring the usual assumption that search engine and advertisers have consistent estimates of the clickthrough rates.
