Moral identity and engagement in sustainable consumption

Purpose This study aims to identify the effects of moral identity on consumer engagement in sustainable consumption, and discover any moderating gender effects. The authors deploy regret and identity theories to propose hypotheses and explain research findings. Design/methodology/approach Data collection was via online survey, and analysed using partial least squares structural equation modelling to test hypotheses. Findings Symbolization and internalization dimensions of moral identity are positively associated with five dimensions of engagement. Moreover, the relationship between moral identity and specific dimensions of engagement in sustainable consumption is stronger among males than females. Originality/value This study suggests a novel mechanism in a hitherto under-researched area in the sustainability and moral identity literature, viz. consumer engagement in sustainable consumption when moral identity is present. This research also adds to current knowledge regarding gender effects in the link between the symbolization and internalization dimensions of moral identity and engagement in sustainable consumption.
