不耐烦购买者的最优定价方案

Optimal Pricing Schemes for an Impatient Buyer

Yuan Deng, Jieming Mao, Balasubramanian Sivan, Kangning Wang

摘要:

耐心的卖家旨在向不耐烦的买家出售商品(即,一个随着时间的推移而折扣效用的人)。买方将在市场上停留一段时间$T$,她的私人价值来自一个公开的分配。卖方的收入最优定价曲线((价格,时间)对序列)是什么?随机化在这里有帮助吗?收益最优定价曲线在多项式时间内可计算吗?我们在本文中回答这些问题。我们给出了一个有效的算法计算收入最优定价曲线。我们表明,定价曲线,张贴在每个时间点的价格,让买家选择她的效用最大化的时间购买,是收入最优的一类更广泛的顺序彩票机制。即,允许销售者在每个时间点张贴彩票菜单的机制不能获得比定价曲线更高的收入。我们还表明,甚至更广泛的一类机制,允许菜单的彩票自适应设置,可以赚取严格高于定价曲线的收入,收入差距可以大到买方的价值分布的支持大小。

英文摘要:

A patient seller aims to sell a good to an impatient buyer (i.e., one who discounts utility over time). The buyer will remain in the market for a period of time $T$, and her private value is drawn from a publicly known distribution. What is the revenue-optimal pricing-curve (sequence of (price, time) pairs) for the seller? Is randomization of help here? Is the revenue-optimal pricing curve computable in polynomial time? We answer these questions in this paper. We give an efficient algorithm for computing the revenue-optimal pricing curve. We show that pricing curves, that post a price at each point of time and let the buyer pick her utility maximizing time to buy, are revenue-optimal among a much broader class of sequential lottery mechanisms. I.e., mechanisms that allow the seller to post a menu of lotteries at each point of time cannot get any higher revenue than pricing curves. We also show that the even broader class of mechanisms that allow the menu of lotteries to be adaptively set, can earn strictly higher revenue than that of pricing curves, and the revenue gap can be as big as the support size of the buyer's value distribution.
