Abstract: | Shelf-based scarcity in the form of relative stocking level depletion significantly affects consumer preferences (van Herpen et al. 2009). While both popularity and quality inferences are induced by stocking-level depletion, this paper demonstrates that popularity (rather than quality) inferences are the primary driver of the effect. Shelf-based scarcity is shown to have an impact in the presence of other signals, such as brand names and quality ratings, which indicates its effect may be widespread. However, its effect on preferences is greatly decreased by the presence of strong prior preferences and/or price promotions, indicating that shelf-based scarcity is likely to affect choices when consumers lack strong prior preferences and under conditions where price promotions are either not present or are similar across alternatives. |
