Is there an Exclusionary Effect of Retroactive Price Reduction Schemes?

Lisa Bruttel (Department of Economics, University of Konstanz, Germany) asks Is there an Exclusionary Effect of Retroactive Price Reduction Schemes?

ABSTRACT: This paper presents an experiment on the loyalty enhancing effect potentially created by retroactive price reduction schemes. Such price reductions are applied to all units bought in a certain time frame if the total quantity passes a given threshold. Close to the threshold, the marginal price the buyer pays for the missing units up to the threshold is very low. A dominant firm can use this effect to exclude potential rivals from competition, which is why some jurisdictions consider retroactive discounts as unlawful. This study shows that there in fact is a loyalty enhancing effect of retroactive discounts and how it relates to risk preferences and loss aversion.
