Capital Accumulation, Productivity and Growth
A consensus has emerged that the remarkable behavior of IT prices provides the key to the surge in US economic growth after 1995. The relentless decline in the prices of information technology equipment and software has steadily enhanced the role of IT investment. Productivity growth in IT-producing industries has risen in importance and a productivity revival is underway in the rest of the economy. The surge of IT investment in the United States after 1995 has counterparts in all other industrialized countries. It is essential to use comparable data and methodology in order to provide rigorous international comparisons. A crucial role is played by measurements of IT prices. The US national accounts have incorporated measures of IT prices that hold performance constant since 1985. Schreyer (2000) has extended these measures to other industrialized countries by constructing "internationally harmonized prices". The acceleration in the IT price decline in 1995 triggered a burst of IT investment in all of the G7 nations — Canada, France, Germany, Italy, Japan, the UK, as well as the US. These countries also experienced a rise in productivity growth in the IT-producing industries. However, differences in the relative importance of these industries have generated wide disparities in the impact of IT on economic growth. The role of the IT-producing industries is greatest in the US, which leads the G7 in output per capita.

Information Technology and the Japanese Economy
In this paper we compare sources of economic growth in Japan and the United States from 1975 through 2003, focusing on the role of information technology (IT). We have adjusted Japanese data to conform to U.S. definitions in order to provide a rigorous comparison between the two economies. The adjusted data show that the share of the Japanese gross domestic product devoted to investment in computers, telecommunications equipment, and software rose sharply after 1995. The contribution of total factor productivity growth from the IT sector in Japan also increased, while the contributions of labor input and productivity growth from the Non-IT sector lagged far behind the United States. Our projection of potential economic growth in Japan from for the next decade is substantially below that in the United States, mainly due to slower growth of labor input. Our projections of labor productivity growth in the two economies are much more similar.
Information technology and the world economy
The purpose of this paper is to analyze the impact of investment in information technology (IT) equipment and software on the recent resurgence in world economic growth. The crucial role of IT investment in the growth of the U.S. economy has been thoroughly documented and widely discussed. Jorgenson (2001) has shown that the remarkable behavior of IT prices is the key to understanding the resurgence of American economic growth. This behavior can be traced to developments in semiconductor technology that are widely understood by technologists and economists.
