N2 - The purpose of this paper is twofold: The first is to examine the information technology (IT) capital investments (including software) and capital stock of the USA and Japan, not merely in the 1990s but from the long-ran historical viewpoint and compare the process of IT Revolution of the two countries, using the data from 1974 to 1998. The second is to check how those investments are justifiable, by calculating the marginal benefits and costs of IT related investments in the USA and Japan. We find that while the USA shows a tendency to overinvest in IT capital relative to non-IT capital throughout the observation period, the opposite is the case in Japan.
