The Valuation of Information Technology Investments by Real Options Analysis

This study establishes a dynamic model under real options analysis to analyze the optimal timing decision of information technology (IT) investments when the output price for firms is stochastic and benefits of IT investments are arisen from the increasing output price, increasing sale, and cost savings. We derive the closed form expression of the timing of IT investments and furthermore prove that IT investments rise at an increasing rate in economic booms and fall in economic busts. This study finds that increasing (decreasing) price volatility will delay (advance) the timing of IT investments. Increasing IT investments, however, may not delay the timing of IT investments. In addition, the decreasing (increasing) efficiency and increasing (decreasing) depreciation of IT investments will delay (advance) the timing of IT investments.
