Consumer behavior towards on-net/off-net price differentiation

This paper explores how consumers react towards price differentiation between on-net and off-net calls in mobile telecommunications – a pricing policy that is common in many mobile telecommunications markets. Based on a survey of 1044 students it is demonstrated that some consumers may suffer from a "price differentiation bias", i.e., a fair number of consumers may overestimate the savings that result from reduced on-net and/or off-net charges, as they do not appear to weigh the prices with the probabilities of placing off-net and on-net calls. This may help to explain why it have been the smaller operators in various countries who have introduced on-net/off-net price differentiation. The paper also discusses the implications that such a consumer bias may have for market competition.
