摘　　要：在网络拍卖里(如eBay),有三种主要的交易制度,一是一口价,二是一般的拍卖,三是立即购买拍卖(auction with buy-it-now).本文利用一个简单的理论,说明这三种制度,其实是卖家在同一个最适化问题下的三种不同的解.换句话说,eBay里,卖家对上述三种上架方式的策略选择,可以在一个统一的理论模型下去内生化(endogenize).其中的关键在于底价及立即购买价之间的相对关系,尤以底价的角色最重要.在这个理论下,本文证明这三种交易制度下的底价的相对大小,有一个固定的排序.我们利用eBay的iPod上架数据,来证实这个排序.In the online auctions(such as eBay), there are three main listing formats for the sellers: Posted price, general auctions, and auctions with buy-it-now. This paper adopts a simple theoretical model to show that these three formats are actually three different solutions of seller’s same optimization problem. In other words, the seller’s listing strategy on eBay can be endogenized in a unified theoretical model. The key determinant is the relative relationship between the reserve price and the buyit-now price, especially the role of the reserve price. Under this theory, the relative value of the reserve price in these three formats has a fixed order. We use eBay’s iPod listing data to verify and confirm this order.
