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

THE INFORMATION AGE:Faster, Better, Cheaper!

MOORE'S LAW: The number of transistors on a chip doubles every 18-24 months(Pentium 4, released November 20,2000, has 42 million transistors).

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.

SEMICONDUCTOR PRICE INDEXES:

Memory and Logic Chips.

 COMPUTER PRICE INDEXES:
