The present research examines the interactive effect of impulsivity and indulgence opportunity on consumers’ indulgent consumptions. Further, we investigate the psychological mechanisms through which this interactive effect occurs. Specifically, we propose that impulsive (vs. non-impulsive) consumers are less likely to intend to engage in indulgent consumption when they are exposed to an opportunity to indulge (i.e., when they contemplate whether to consume a tempting item) as opposed to when they are not exposed to the indulgence opportunity. The results of Study 1 showed that impulsive consumers, in the presence of an indulgence opportunity (compared to its absence), exhibit a reduced likelihood of engaging in subsequent indulgent consumptions. For non-impulsive consumers, however, there is no difference in indulgent consumptions based on the presence and absence of an indulgence opportunity. The results of Study 2 demonstrate that the interactive effect of impulsivity and indulgence opportunity on indulgent consumptions is mediated by goal conflict and negative affect, in a sequential manner. Based on these findings, we provide theoretical and practical implications for consumers interested in minimizing self-control failure and for policy makers interested in facilitating desirable consumer behaviors.
