Japan’s Potential Growth in a World Perspective by Dale W. Jorgenson Harvard University http://post.economics.harvard.edu/faculty/jorgenson/ Presented at the RIETI Policy Symposium Determinants of Total Factor Productivity and Japan's Potential Growth: An International Perspective Tokyo, Japan July 25, 2006 Economic Growth in the Information Age INTRODUCTION: Prices of Information Technology THE INFORMATION AGE: Faster, Better, Cheaper! ROLE OF INFORMATION TECHNOLOGY: IT Prices and the Cost of Capital WORLD GROWTH RESURGENCE: IT Investment and Productivity Growth ECONOMICS ON INTERNET TIME: The New Research Agenda 1 THE INFORMATION AGE: Faster, Better, Cheaper! MOORE'S LAW: The number of transistors on a chip doubles every 12-24 months. (Itanium 2 Processor, released November 8, 2004, has 592 million transistors.) INVENTION OF THE TRANSISTOR: Development of Semiconductor Technology. THE INTEGRATED CIRCUIT: Memory Chips; Logic Chips. SIA Annual Report 2005: In 1978, a commercial flight between New York and Paris cost $900 and took seven hours. If the principles of Moore's Law were applied to the airline industry, that flight would now cost about a penny and take less than one second. 2 3 Source: No Exponential is Forever, Gordon Moore ftp://download.intel.com/research/silicon/Gordon_Moore_ISSCC_021003.pdf HOLDING QUALITY CONSTANT Matched Models and Hedonics SEMICONDUCTOR PRICE INDEXES: Memory and Logic Chips.
