1 What is the New Economy? Tokyo June 29-30, 2007 By Dale W. Jorgenson, Mun Ho, Jon Samuels, and Kevin Stiroh Harvard University, Resources for the Future, Johns Hopkins University, and the Federal Reserve Bank of New York

2 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 AMERICAN GROWTH RESURGENCE: IT Investment and Productivity Growth ECONOMICS ON INTERNET TIME: The New Research Agenda

3 THE INFORMATION AGE: Faster, Better, Cheaper! MOORE (1998): "If the automobile industry advanced as rapidly as the semiconductor industry, a Rolls Royce would get half a million miles per gallon, and it would be cheaper to throw it away than to park it." INVENTION OF THE TRANSISTOR: Development of Semiconductor Technology. THE INTEGRATED CIRCUIT: Memory Chips; Logic Chips. MOORE'S LAW: The number of transistors on a chip doubles every months(pentium 4, released November 20,2000, has 42 million transistors).

10 ROLE OF INFORMATION TECHNOLOGY: Growth of Output. OUTPUT SHARES OF IT: Computers, Communications Equipment, Semiconductors, and Software. OUTPUT CONTRIBUTION BY TYPE: Computers, Communications Equipment, Semiconductors, and Software. OUTPUT CONTRIBUTION OF IT: IT-Producing, IT-Using, and Non-IT Value Added.

11 4.0 Value Added Shares of Information Technology by Type, Share of Current Dollar GDP Computers Communications Equipment Electronic Components Software and Computer Services Total IT

12 0.8 Industry Contributions to Value Added Value added weighted contributions of industry value added Annual Contribution (%) Computers Communications Equipment Electronic Components Software and Computer Services

13 4.50 Industry Contributions to Value Added Growth Value added weighted contributions of industry value added Annual Contribution (%) Non-IT Industries IT-Using Industries IT-Producing Industries

14 Comparison of Production Possibility Frontier and Aggregate Production Function Annual Growth (%) Aggregate Production Function Value-Added Aggregate Production Possibility Frontier Value-Added

15 ROLE OF INFORMATION TECHNOLOGY: Contribution of Capital Input. INPUT SHARES OF IT: Computers, Communications Equipment, and Software. CAPITAL CONTRIBUTION: IT versus Non-IT Capital Services.

16 IT Share of Capital Input, Share of Current Dollar GDP

17 Capital Input Contribution of Information Technology 2.50 Annual percentage growth rates, weighted by income shares Annual Contribution (%) Non-IT Capital Services IT Capital Services

18 GROWTH IN THE NEW MILLENNIUM: IT Investment and Productivity Growth. TOTAL FACTOR PRODUCTIVITY: IT-Producing, IT-Using, and Non-IT Production. SOURCES OF U.S. ECONOMIC GROWTH: Capital Input, Labor Input, and TFP. AVERAGE LABOR PRODUCTIVITY GROWTH: Capital Deepening, Labor Quality, TFP.

19 1.60 Industry Contributions to Productivity Growth Domar weighted productivity Non-IT Industries IT-Using Industries IT-Producing Industries

23 ECONOMICS ON INTERNET TIME: The New Research Agenda. The Solow Paradox -- we see computers everywhere but in the productivity statistics -- versus the Information Age. Equity Valuations and Growth Prospects: accumulation of intangible assets versus irrational exuberance. Widening Wage Inequality:capital-skill complementarity versus skill-biased technical change. Modeling IT and the semiconductor industry: permanent versus transitory contributions to economic growth.
