摘要
考虑网上拍卖与传统拍卖相比的特性,包括竞标者随机到达,末尾抢标效应,拍卖平台的存在和收费,以及多物品多批次,系统地研究多物品网上拍卖中的一些重要问题.结果表明,竞标者估值离差越大的商品越适合通过拍卖来进行销售,但前提是网络用户基础必须要达到一定规模;在统一分析框架下,分别求解了卖者最优的公开保留价格和隐藏保留价格,并证明了隐藏保留价格能给卖者带来更多的期望利润;在考虑到拍卖平台和卖者目标不一致的条件下,研究表明降低陈列费增加佣金比例的同时缩短拍卖的持续时间有利于设计出激励相容的最优拍卖机制;由于在一次拍卖中拍卖的物品数量并非越多越好,分别在单批次和多批次拍卖下求解了卖者在单批次中应该拍卖的最优批量.
