英文文献作者：John Kennes,Daniel le Maire,Sebastian Roelsgaard
英文文献摘要：
This paper offers expected revenue and pricing equivalence results for canonical models of pricing and matching. The equivalence of these models is centered on the assumption that there are large numbers of buyers and sellers and the assignment of buyers within a submarket of sellers is random. Therefore, the distribution of buyers to sellers is approximated by the Poisson distribution. The list of canonical matching models includes the models developed by Burdett and Judd (1983), Shimer (2005), and McAfee (1993). In the Burdett and Judd (1983) model, buyers post prices and the equilibrium features price dispersion because identical buyers play mixed strategies. In the Shimer (2005) model, sellers post a vector of prices corresponding to different buyer types. In equilibrium, all identical buyers pay the same price. In the McAfee (1993) model, equilibrium pricing is determined by simple second price auctions. McAfee’s model also features price dispersion, because the number of bidders at each auction is stocastic.
本文给出了定价与匹配规范模型的期望收益与定价等价结果。这些模型的等价性集中于假设有大量的买家和卖家，以及买家在一个由卖家组成的次级市场中的分配是随机的。因此，买卖双方的分布近似于泊松分布。典型的匹配模型包括Burdett和Judd(1983)、Shimer(2005)和McAfee(1993)开发的模型。在Burdett和Judd(1983)模型中，由于相同的买家采取混合策略，买方后价格和均衡具有价格离散特征。在Shimer(2005)模型中，卖方发布了一个对应于不同买家类型的价格向量。在均衡中，所有相同的买家支付相同的价格。在McAfee(1993)模型中，均衡定价是由简单的二次价格拍卖决定的。McAfee的模型还具有价格离散的特点，因为每次拍卖的竞标者数量都是股票。
