摘要
网上一口价拍卖作为网上拍卖的创新模式,打破了固定拍卖结束时间的局限因而得到广泛应用。网上一口价拍卖有3种比较典型的方式,投标者的决策决定了拍卖的最终结果,也是拍卖理论研究的重点之一。在独立的私有估价模型下,分别对这3种拍卖方式的顾客投标策略进行研究,结果表明,在固定一口价中,估价高于一口价的投标者的最优选择是及早选择一口价;在临时一口价中存在一个均衡点,使估价高于此均衡点的投标者及早选择一口价是最优的;持久一口价中存在一个门限函数和一个均衡点,使估价满足门限函数或高于均衡点的投标者及早选择一口价是最优的。
Online auctions with a buyout price, as an innovation modes of Internet auction, are applying widely because of breaking the limitation of fixed time ending. There are some forms of huyout price, among which fixed huyout price, temporary huyout price and permanent huyout price, are most typical. The decisions of bidders often make the final result of auction certain and are also one of the important aspects to study for scholars. The paper studies the bidders＇ strategies in different three forms of huyout price under the situation of independent private value. The results show that the bidder who thinks the value is higher than the buyout price is to use huyout price early in fixed huyout auction; there is an equilibrium point which makes the bidder with higher value than huyout price choose the huyout option early in temporary huyout auction ; and in permanent huyout auction＇ a threshold function and an equilibrium point are present, The best strategy is to choose the huyout option for bidder whose value meets the threshold function or the need of the equilibrium.
