Information Technology and Productivity Growth Across Countries and Sectors
The extraordinary success of the U.S. economy and the parallel growth slowdown of the large European countries and Japan in the 1990s bear a simple rationale. The United States has eventually benefited from the effective adoption of information technologies. The introduction of the newly installed IT capital has not instead enhanced aggregate capital accumulation and TFP growth in Europe and Japan. At least on impact, IT capital has mainly displaced existing capital and methods of production rather than supplementing them. The limited growth-enhancing effects from information technologies in countries other than the United States have occurred in the IT-producing sectors, while the IT-using industries have contributed the bulk of productivity gains in the United States.
