为什么竞争性市场会趋向于一级价格拍卖?

Why Do Competitive Markets Converge to First-Price Auctions?

Renato Paes Leme, Balasubramanian Sivan, Yifeng Teng

摘要:

我们考虑一个设置中,投标人参与多个拍卖由不同的卖家,并优化他们的出价为\emph{aggregate}拍卖。我们通过制定卖家之间的博弈来分析这种设置,卖家的策略是选择一个拍卖来运行。我们的分析旨在揭示展示广告市场格局的最新变化:在这里,广告交易所(卖家)早些时候主要运行第二价格拍卖,随着时间的推移,他们转向了第一价格拍卖的变体,最终谷歌的广告交易所在2019年转向了第一价格拍卖。我们的模型和结果提供了一个解释,为什么第一价格拍卖发生在这样的竞争市场的自然均衡。

英文摘要:

We consider a setting in which bidders participate in multiple auctions run by different sellers, and optimize their bids for the \emph{aggregate} auction. We analyze this setting by formulating a game between sellers, where a seller's strategy is to pick an auction to run. Our analysis aims to shed light on the recent change in the Display Ads market landscape: here, ad exchanges (sellers) were mostly running second-price auctions earlier and over time they switched to variants of the first-price auction, culminating in Google's Ad Exchange moving to a first-price auction in 2019. Our model and results offer an explanation for why the first-price auction occurs as a natural equilibrium in such competitive markets.
