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:
Lessons for Europe
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.
Transistor Density on Micro Processors and Memory Chips
HOLDING QUALITY CONSTANTMatched Models and Hedonics
SOFTWARE:
Prepackaged, Custom, and Own-Account.
SEMICONDUCTOR PRICE INDEXES:
Memory and Logic Chips.
COMPUTER PRICE INDEXES:
The BEA-IBM Collaboration.
COMMUNICATIONS EQUIPMENT:
Terminal, Switching, and Transmission.

ECONOMICS ON INTERNET TIME: Lessons for Europe.
• Modeling IT and the semiconductor industry: permanent versus transitory contributions to economic growth.
•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.
