We study the evolution of prices in markets assisted by price-comparison engines. We use laboratory data obtained under two industry sizes and two conditions concerning the sample (complete, incomplete) of prices available to informed consumers. Distributions are typically bimodal. One of the two modes, corresponding to monopoly prices, tends to increasingly attract prices over time. The second one, corresponding to interior prices, presents a decreasing trend. Monopoly pricing can be used as an insurance against more competitive (but riskier) behavior. In fact, subjects earning low profits due to interior pricing in the past are more likely to choose monopoly pricing.
