Negative consumer value and loss leading

Résumé

Large retailers competing with smaller stores that carry a narrower range can exercise market power by pricing below cost for some of their products. Below-cost pricing arises as an exploitative device rather than a predatory device (e.g., Chen and Rey, 2012). Unlike standard textbook models, we show that positive consumer value is not required in these frameworks. Large retailers can sell products offering consumers a negative value. We use this insight to revisit some classic issues in vertical relations.
