Studies have shown that within-domain compensatory consumption can successfully repair the damaged self, but other research indicates that it can undermine self-control because such consumption causes self-threat rumination that impairs self-regulatory resources. This paper aims to identify a boundary condition that reconciles and explains these contradictory findings.

The authors conducted three experiments to show that within-domain compensatory consumption undermines self-control, but only in some situations. They test a boundary condition (i.e. type of connections between within-domain products and self-threat domain) for the effects of such consumption on self-threat rumination and self-control.

This paper demonstrates that within-domain (but not across-domain) compensatory consumption induces rumination and reduces subsequent self-control, but only when the product’s connection to the self-threat domain is made explicit through brand names or slogans. When the connection is merely implicit, rumination and self-control deficits are not observed.

Consumers may seek certain products to bolster threatened aspects of their self-concept. Marketing tactics that explicitly highlight connections to such self-aspects can lower a consumer’s self-control resulting in stronger purchase intent, while at the same time hindering the possibility of self-concept repair. Managers need to be wary of ethical concerns.

This research qualifies the existing findings by presenting “type of product connection” as a key determinant of within-domain compensatory consumption’s impact on self-control. Researchers need to be conscious of the type of products (explicitly vs implicitly connected to the self-threat domain) they use in compensatory consumption studies, because this may influence their findings.

This study aims to follow a rigorous approach to identify, critically analyze and synthesize 75 papers published from 2000 to 2022.

The study presents a systematic literature review on identity expressiveness (IE), clarifying and expanding what is currently known about the concept.

To synthesize current knowledge on IE, the study uses the overarching framework of antecedents-phenomenon-consequences, using this same framework to identify gaps and future research directions. The findings show individual and brand-related factors such as the need for uniqueness and anthropomorphism as antecedents of IE, and eWOM/WOM, impulse purchases and upgrading to more exclusive lines as consequences of IE.

The study contributes to theory by synthesizing and mapping current understanding of the state of knowledge on the concept of IE while highlighting gaps in the extant literature and paving future research directions for scholars in the field.

The study offers useful insights for practitioners, broadening marketers’ actionable options in identity-based marketing. Marketers can use insights from this study to inform marketing strategy and communication campaigns for different types of brands.

To the best of the authors’ knowledge, this study is the first of its kind and offers an integrative review of the current literature on IE, thus enhancing understanding of the concept, its antecedents and consequences. The study also contributes to knowledge by highlighting future research priorities for researchers in this field of enquiry.
