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 consumer 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
research.
