Although the effect of monetary sunk costs on decision-making is widely discussed, research is still fragmented, and results are sometimes controversial. One reason for this incomplete picture is the missing differentiation between the effect of sunk costs on utilization and progress decisions and its respective moderators. This article presents the results of a meta-analytic review of 98 effect sizes of the sunk-cost effect, with special emphasis on the decision-specific influence of moderators. The results show clear evidence that the sunk-cost effect emerges, though its effect size and the influence of the moderators are contingent on the respective decision type. In particular, we find support for the idea that the sunkcost effect is attenuated by time in utilization decisions. The results also reveal that older adults are less likely to fall prey to the sunk-cost effect than younger adults.

Personalized dynamic pricing (PDP) involves dynamically setting individual-consumer prices for the same product or service according to consumer-identifying information. Despite its profitability, this pricing provokes strong negative fairness perceptions, explaining why managers are reluctant to implement it. This research provides important insights into the effect of two PDP dimensions (price individualization level and segmentation base) on fairness perceptions and the moderating role of privacy concerns. The results of two experimental studies indicate that consumers perceive individual prices as less fair than segment prices. They also evaluate location-based pricing as less fair than purchase history-based pricing. Consumer privacy concerns moderate these effects.

Purpose – The purpose of this paper is to elaborate on the differences between price partitioning and drip pricing with regard to their influence on price recall, purchase intentions and fairness perceptions. In many industries, sellers advertise low prices and reveal other surcharges sequentially as the customer goes through the buying process. To date, little is known about how these sequential, or drip-pricing, techniques influence consumer behavior. Design/methodology/approach – The study is based on an experimental between-subjects design (N = 95) with two groups. The data collection was conducted with a mixed scenario/stimuli-based online survey for a virtual travel agent. Findings – The findings reveal that underestimation of the total price of an offering is significantly weaker when prices are presented sequentially rather than partitioned. In addition to reduced purchase intentions, drip pricing may negatively affect fairness perceptions when consumers feel deceived by the seller. Originality/value – The study replicates findings of previous research on price partitioning but is one of the first empirical studies to examine the influence of sequence in price presentations. With this focus, the study opens up new avenues for pricing research.

Purpose – In drip pricing, companies advertise low prices for products or services and then tack on additional surcharges later in the purchase process. This tactic has not only become popular for airlines but also for other online services, such as retailers and telecommunication companies. Despite the widespread use of drip pricing in the marketplace, little is known about its effects on consumer behavior. The purpose of this paper is to compare the effects of drip pricing with those of price partitioning. Specifically, it elaborates on perceived value, perceived deception, purchase intentions, and the moderating effect of price consciousness. Design/methodology/approach – The paper develops a conceptual framework and tests four hypotheses with an experimental study on a purchase decision for a continental flight booked through an online travel agent. The experiment is based on a between-subjects design with two groups (n=130). The data are analyzed with multivariate statistics and structural equation modeling. Findings – The findings reveal that drip pricing for service offerings leads to inferior results compared with partitioned pricing in terms of perceived value, perceived deception, and, ultimately, purchase intentions. The findings also indicate that the effects differ depending on the customer’s price consciousness. Originality/value – The study draws from previous studies on partitioned pricing and replicates their findings. However, it is one of the first studies to elaborate on moderators and mediators of the consequences of drip pricing in a service context.
