Abstract

We propose a model of price competition where consumers exogenously differ in the number of prices they compare. Our model can be interpreted either as a non-sequential search model or as a network model of price competition. We show that (i) if consumers who previously just sampled one firm start to compare more prices all types of consumers will expect to pay a lower price and (ii) if consumers who already sampled more than one price sample (even) more prices then there exists a threshold - the informational divide - such that all consumers comparing fewer prices than this threshold will expect to pay a higher price whereas all consumers comparing more prices will expect to pay a lower price than before. Thus increased search can create a negative externality and it is not necessarily beneficial for all consumers. © 2012 Elsevier Inc.
