Information technology investments and firm value

Our objective in this paper is to develop a firm value model to assist IT managers and researchers in understanding the multiple effects that IT investments have on firm value. This firm value approach adds to the process-oriented approach through simultaneous evaluation of all of the factors that affect firm value. It is crucial for IT professionals to recognize the complex and diverse implications of IT investments on firm value. The implications of the firm value approach include forcing IT managers to think in terms of both industry and company-specific effects of IT investments, to consider both the magnitude and duration of competitive advantage due to IT investments, and the implications of the effect that IT investments have on risk and its relation to firm value. We demonstrate an application of the firm value framework by evaluating a major stream of research in MIS-event studies of IT investment announcements.
