摘要：We examine the pattern of information technology (IT) capital adjustment using data from U.S. industries. Using the gap between actual and desired IT capital stocks, we estimate the shape of the adjustment cost function in IT investment. Both ordinary least squares and nonparametric regression estimates support irreversibility in IT investment.
