Intertemporal pricing and price discrimination: a semiparametric hedonic analysis of the personal computer market
用半参数模型分析个人电脑的跨期定价，检验厂商是否对高端产品实行差别定价，发现组件定价存在非线性效应，且优质厂商仅对最先进产品收取溢价。
Abstract We apply a smooth coefficient semiparametric model to a unique high‐frequency data set to examine the intertemporal pricing of personal computers. Furthermore, we test whether firms charge differential component prices for their top performance personal computers and whether premium firms charge both a premium for all their computers and a premium for their top performance ones. We find nonlinear effects in the pricing of personal computer components. We also find that firms in general do not charge differential prices for the components of their top performance computers. In addition, high‐quality firms charge higher premia only for their most advanced products. Copyright © 2006 John Wiley & Sons, Ltd.
