We contrast memory-based and stimulus-based choices, using dual-process theories such as Kahneman and Frederick’s system 1/system 2 dichotomy. Systems 1 and 2 are conceptualized as distinct modes of thought, the former automatic and affective, the latter controlled and deliberate. Cognitive load impedes system 2, yielding greater reliance on system 1. In memory-based choice, consumers must maintain relevant options in working memory. Thus, memory-based choices are associated with greater cognitive load than stimulus-based choices. Indeed, we find that memory-based choices favor mmediately compelling, affect-rich system 1 options, whereas stimulus-based choices favor affect-poor options whose attractiveness emerges from deliberative system 2 thought.

Dynamic pricing practices by sellers in response to segment and individual-level differences have been made more feasible as internet buyer behavior increases. While benefits from these pricing practices can accrue to sellers and buyers, the potential for (un)fairness perceptions to mitigate these advantages is important. In an effort to investigate these issues, this article reports the results of three studies that examine the effects of seller-, consumer-, time-, and auction-based price differences on perceived price fairness and purchase satisfaction. The findings underscore the potential negative effects associated with price differences from dynamic pricing practices.
