Consumer Acceptance and Use of Information Technology: Adding consumption theory to UTAUT2

This paper studies IT acceptance in a consumer context. It firstly takes economics factors into consideration, and proposes a theoretical model by incorporating consumption theory into UTAUT2 (which studies consumer acceptance by extending UTAUT). The consumption theory, which is prominent in Economics but not yet applied in IS, provides explanation for consumers' acceptance of technology. Consumption theory suggests income (absolute income, relative income, and permanent income) to be critical to consumers’ intention. Our plan is to show that economic perspectives should be considered in analyzing consumers' acceptance and use of information technology, and empirically that the extended UTAUT2 with Consumption theory provides better explanatory value than UTAUT2 without the Consumption Theory, and generate theoretical and managerial implications for future
