摘要: 对eBay上一类网上英式拍卖,给出了设置保留价和不设置保留价时卖方期望收入的表达式,发现顾客总人数与顾客估价的最大偏差对卖方的期望收入起互补作用,并证明了卖方的期望收入都是补偿因子的严格递增的凹函数,当顾客足够多时,无保留价拍卖最优起始价产生的期望收入与含保留价拍卖最优保留价产和的期望收入相同.

关键词: 网上拍卖, 保留价, 起始价

Abstract: For an online English auction on eBay, this paper presents the expressions for the seller's expected revenue with or without the reserve price, and finds that the total number of bidders and the absolute difference between the upper bound and the lower bound of bidders' valuation are compensated with each other on the expected revenue. It is shown that the expected revenues are concave and strictly increase at the compensating rate, and that when bidders are enouth the maximum expected revenues almost remain the same whether or not the reserve price is set.

Key words: online auction, reserve price, starting price
