本文研究了不带拟线性约束的单物品规范私人价值拍卖模型。我只假设投标人是风险厌恶和不可分割的好销售是一个正常的好。我表明,去除准线性会导致拍卖设计问题的质的不同解决方案。预期收益不再是最大化使用标准拍卖,分配良好的出价最高。相反,拍卖师通过使用一种机制,将物品分配给许多不同的投标人中的一个,每个投标人都有严格的正概率,从而更好地利用投标人的偏好。我引入了一个概率需求机制,把赢得不可分割的好像一个可分割的好在净供应的概率。在投标人足够多的情况下,它比任何标准拍卖都有更大的期望收益;在完全信息下,它实现了帕累托有效分配。
I study the canonical private value auction model for a single good without the quasilinearity restriction. I assume only that bidders are risk averse and the indivisible good for sale is a normal good. I show removing quasilinearity leads to qualitatively different solutions to the auction design problem. Expected revenue is no longer maximized using standard auctions that allocate the good to the highest bidder. Instead, the auctioneer better exploits bidder preferences by using a mechanism that allocates the good to one of many different bidders, each with strictly positive probability. I introduce a probability demand mechanism that treats probabilities of winning the indivisible good like a divisible good in net supply one. With enough bidders, it has greater expected revenues than any standard auction; and under complete information, it implements a Pareto efficient allocation.
