Studies that integrate online consumers’ trust toward the e-vendor with key constructs from technology acceptance models draw on one-dimensional or second-order conceptualizations of trust to explain shopping behavior. However, marketing and consumer research supports that a richer understanding of behavior, in particular relational behavior, is gained when trust is decomposed into three dimensions. Using Gefen, Karahann and Straub’s (2003) integrated website response model as a theoretical foundation, this research investigate the relationships between three dimensions of trust (consumers’ beliefs about the e-vendor’s integrity, benevolence and competence) and two key constructs from technology acceptance models (perceived ease of use and perceived usefulness of commercial websites) to explain online consumers’ intentions to engage in a business relationship with the e-vendor. The empirical results show the superiority of the tri-dimensional trust model over the one-dimensional one.
