Pigou Meets Wolinsky: Search, Price Discrimination, and Consumer Sophistication

Abstract

We study the competitive effects of personalized pricing in horizontally differentiated markets with search frictions. We integrate the possibility of first degree price discrimination into the classic Wolinsky (1986) framework of consumer search. If all consumers are rational, personalized pricing leads to higher consumer surplus if and only if there are no search frictions. If all consumers are unaware that firms price discriminate, i.e. are naive as in Eyster and Rabin (2005), this result is reversed: Personalized pricing improves consumer surplus unless search costs are prohibitive.
