声誉溢价是否总是存在?——来自淘宝网的实证研究Does Reputation Premiums always Exit?——An Empirical Study from Taobao
钱炳,周勤
摘要(Abstract):
通过搜集淘宝网上Nokia N97手机的600个交易样本,就卖家声誉对商品价格的影响进行了实证研究。研究发现,卖家累积的声誉值与"声誉溢价"之间存在""型关系:在声誉建立的初始阶段,声誉值增加"溢价"减少;只有当声誉值累积到一定程度,声誉效应才会显现,即随着声誉值的增加,"溢价"效应开始显现。但是声誉对价格的影响较弱。卖家获得的差评对价格有十分显著的负面影响。研究还发现,网络交易中的声誉评价可能存在"噪声",从而导致声誉体系无法有效发挥作用。
