Abstract

This paper presents an updated estimation of the total factor productivity (TFP) of the U.S. economy following the two preceding empirical studies, Basu et al. (2001) and Burnside et al. (1995). Based on these two estimation approaches, both of which carefully handle the potential estimation bias stemming from cyclical utilization, we verified that the TFP growth in the late 90s was, to some extent, higher than that in the 80s. Further, our estimation results support the following views; (i) the effect of the higher growth of TFP on the level of output was permanent, however, (ii) the acceleration of growth rate of output was transitory in the sense that the TFP growth rates after 1999 turn out to be nearly the same as those in the 80s and early 90s.

Key Words:
TFP, New Economy, capital utilization
