3 Economic Growth in the Information Age INTRODUCTION: Prices of Information Technology 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

4 THE INFORMATION AGE: Faster, Better, Cheaper! MOORE'S LAW: The number of transistors on a chip doubles every 24 months. (The Tukwila Processor to be released later in 2008 will have more than two billion transistors.) 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. INVENTION OF THE TRANSISTOR: Development of Semiconductor Technology. THE INTEGRATED CIRCUIT: Memory Chips; Logic Chips.
