The Resurgence of Growth in the Late 1990s: Is Information Technology the Story?
研究了20世纪90年代后期美国劳动生产率回升的原因，发现信息技术资本使用激增和计算机生产效率提升解释了约三分之二的生产率加速增长。
The growth of U.S. labor productivity rebounded in the second half of the 1990s, after nearly a quarter century of sluggish gains. We assess the contribution of information technology to this rebound, using the same neoclassical framework as in our earlier work. We find that a surge in the use of information technology capital and faster efficiency gains in the production of computers account for about two-thirds of the speed-up in productivity growth between the first and second halves of the 1990s. Thus, to answer the question posed in the title of the paper, information technology largely is the story.
