Alan Greenspan was puzzled by the data on his computer screen. Capital expenditures in high technology were rising sharply, unemployment was declining, prices were holding steady and profits were rising. At the same time, the Labor Department’s statistics showed that productivity had decreased by one percent during the second quarter. Greenspan did not agree with the productivity data. He found the missing link in the Survey of Current Business from the Bureau of Labor Statistics, Woodward [44], which indicated that business inventories were shrinking significantly while the economy was growing. This suggested that new computer technology was allowing just-in-time orders. Instead of stocking products weeks or months in advance, businesses could keep detailed track of what was needed and order within days, while competitive pressures were forcing quality control. Greenspan eventually became convinced by this argument and voiced it publicly in the State of the Economy address before the Committee on Ways and Means, U.S. House of Representatives, January 20, 1999.
