This article, analyzes the impact on consumer prices of the size and bias of price comparison search engines. we develop a model, related to Burdett and Judd (1983) and Varian (1980), and test experimentally several theoretical predictions. The experimental results confirm the model’s...

This study examines the evolution of prices in markets with Internet price-comparison search engines. The empirical study analyzes laboratory data of prices available to informed consumers, for two industry sizes and two conditions on the sample (complete and incomplete). Distributions are...

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...

In a four-treatment experiment, we test some of the hypotheses in García-Gallego et al. (2004) concerning competition among a number of firms of which some (or all) are indexed by a price-comparison engine facilitating buyers’ search process. In this paper, we isolate individual behavior from...
