Current theories of information technology (IT) usage do not include the role of managerial incentives and control mechanisms in motivating individual IT usage behavior. Drawing on agency theory in the microeconomics literature, this paper develops a principal-agent model (PAM) of intraorganizational IT usage which addresses this issue. This model is empirically validated using data collected from a laboratory experiment. PAM and TAM (technology acceptance model) variables are then combined within a TPB (theory of planned behavior) framework to propose an integrated model of IT usage. A comparison of the explanatory power of PAM, TAM, and the integrated model indicates that explanation of IT usage can be increased by adding incentives and control as additional determinants of behavioral intention, over and above the attitudinal variables in TAM.
