3. The Nature and Importance of Warehousing
In 1999, $75 billion, or 0.8 percent of GDP was spent on warehousing.
The total supply of U.S. warehousing space in 1999 was 6.1 billion square feet, an increase from 1990 of 700 million square feet of space.
Warehousing provides time and place utility for raw materials, industrial goods, and finished products, allowing firms to use customer service as a dynamic value-adding competitive tool.
