The impact of self-efficacy, ease of use and usefulness on e-purchasing: An analysis of experienced e-shoppers

The objective of the present research is to study the Internet purchasing behaviour of consumers who are experienced with the channel, employing a dual perspective for the analysis: (1) present e-purchasing behaviour and (2) future repurchasing behaviour measured through repurchasing intentions. On the basis of this approach, we attempt to understand the effect of perceived self-efficacy, ease of use and usefulness on both types of behaviour and the links between them. Furthermore, the research includes other variables related to Internet experience, extracted from models widely tested in the literature. These variables, namely, acceptance, frequency of use and satisfaction with the Internet, act as antecedents of e-purchasing behaviour and permit a deeper analysis of the consumer. The results obtained show that self-efficacy and usefulness are important perceptions in explaining the behaviour of experienced consumers, while ease of use does not have a significant influence.
