Impact of social media influencers' credibility on millennial consumers' green purchasing behavior: a concept paper on personal and social identities

Purpose - The purpose of this paper is to provide the theoretical insights with regard to the green purchasing intention–behavior gap and the role played by social media influences in abating this gap. This paper takes into consideration a wider aspect with regard to the antecedents of behavioral intention through personal and social identities in place of the antecedents presented in the theory of planned behavior and social-identity theory. Furthermore, as the theories lack an explanation of how to reduce the intention–behavior gap, this paper also argues the source credibility model (SCM) in explaining the impact that social media influences can have on the behavioral gap. Design/methodology/approach - Hypothetical deductive method is proposed for this concept paper under the positivism research paradigm. Findings - Not applicable as this is a concept paper. However, the paper discusses the theoretical and managerial implications. Research limitations/implications - This is a concept paper. Yes this paper discusses the theoretical, managerial, and social/ecological implications. Practical implications - This paper highlights the relevance of consumers' personal and social identities when consumers make purchasing decisions regarding green products.
