Interaction of the underdog with equality and scarcity

Purpose The purpose of this paper is to investigate the moderating roles of equality and scarcity on the impact of underdog brand positioning on consumer purchase intentions. Beyond testing the relationship between underdog brand positioning and purchase intentions (Study 1), the study examines how the equality perception affects consumer choices on underdog brands (Study 2) and how the reasons for product scarcity influence purchase intentions of consumers with prosocial orientations (Study 3). Design/methodology/approach A research model is developed, depicting the impact of underdog brand positioning on purchase intentions via social value orientations and scarcity types. The conceptual model is validated using moderation process modeling and data for which are collected through sets of structured questionnaires analyzed through PROCESS modeling in SPSS. Findings The findings support that compared with top dog brand positioning, underdog brand positioning has a greater impact on consumers’ purchase intentions, and consumers with prosocial orientations generate greater purchase intentions than consumers with proself orientations. In addition, the demand-caused product scarcity also moderates the relationship between underdog brand biography and purchase intentions. Originality/value The study contributes to the ongoing research on brand positioning by examining the associations between equality perception and purchase intentions in the context of underdog brand biography. The study also shows the value of demand-caused scarcity as a moderator of the underdog brand–purchase intention linkage.
