Purpose - While researchers have argued that multicultural marketplaces are conceptually different from other types of marketplaces, the marketing literature has only recently begun to develop multicultural perspective studies, and very little research has been done to examine intergroup complexities in consumption contexts (Demangeot et al., 2015). The purpose of this study is to fill this research gap by developing and empirically testing a research model to examine the effects of socio-political constructs and intergroup-based emotional variables on consumer decisions to consume cross-ethnic products. Design/methodology/approach - A questionnaire designed to assess the effects of socio-political constructs and intergroup-based emotional variables on consumer decisions to consume cross-ethnic products was developed and administered to 294 students at a Midwestern US university. The data were analysed using partial least squares structural equation modelling (PLS-SEM) techniques. Findings - Results indicate that all path coefficients are significant. Social dominance, intergroup anxiety and intergroup experience were found to be important predictors of intergroup tolerance and, importantly, intergroup tolerance was found to significantly affect consumer attitude toward cross-ethnic products. Research limitations/implications - In terms of limitations and future research implications, this research suffers from inherent limitations associated with self-reported survey research in a limited geographic region. Accordingly, study respondents may not be representative of consumers across the nation or the world, the respondents may not have understood the questions in the intended manner, and reported intentions may not reflect actual behaviour. This study was conducted among college students, but other target segments may have different intergroup experiences and perceptions of ethnic products. Practical implications - Findings from this research suggest that firms offering ethnic products can increase crossover consumption appeal by implementing marketing communication programmes that integrate cultural forums and event tactics to promote positive intergroup experiences and tolerance among their multicultural customers. Social implications - Regarding policy implications, public policymakers and social thinkers may use the findings of this study as a prism to better explicate intercultural dealings among multicultural consumers. The contention of this study about public policy implications is supported by Neal et al.' s (2013) perspectives on how consumption situations can serve as a lens for explicating intergroup emotions in multicultural marketplaces. Originality/value - This is one of only a few studies in marketing to assess the effects of socio-political constructs in a consumption context. This is the first known study to underscore the importance of intranational ethnic differences and assess the effects of socio-political and intergroup-based emotional variables on attitude to consume ethnic products, specifically.
