Raising the Speed Limit: U.S. Economic Growth in the Information Age
研究了1990年代末美国经济表现优异的原因，发现产出增长加速近两个百分点，主要归因于资本积累、工时增加和全要素生产率增长，其中信息技术驱动的生产率加速最为显著。
This paper examines the underpinnings of the successful performance of the US economy in the late 1990s. Relative to the early 1990s, output growth has accelerated by nearly two percentage points. We attribute this to rapid capital accumulation, a surge in hours worked, and faster growth of total factor productivity. The acceleration of productivity growth, driven by information technology, is the most remarkable feature of the US growth resurgence. We consider the implications of these developments for the future growth of the US economy.
