Abstract
Firms have been increasingly using social commerce platforms to engage with customers and support their brand value co-creation. While social commerce is now bringing a variety of benefits to business, it has also challenged marketing ethics surrounding online consumer privacy. Drawing on the trust-commitment theory, we develop a model that aims to create an ethical and trustworthy social commerce community for brand value co-creation by examining the impacts of online consumer privacy concerns (namely privacy risk and privacy control) and social interaction constructs (namely consumer-peer interaction and collaborative norms) on consumers' psychological reactions. Using an empirical study, we find that: (1) privacy risk, privacy control, and collaborative norms significantly influence consumers' trust; (2) consumer-peer interaction and collaborative norms are positively related to relationship commitment; and (3) relationship commitment and trust positively affect consumers' brand value co-creation in the context of social commerce. Theoretical and practical implications are discussed.
