WPI: The abbreviation for Wholesale Price Index, which is an index of the prices paid by retail stores for the products they would ultimately resell to consumers. The Wholesale Price Index, abbreviated WPI, was the forerunner of the modern Producer Price Index (PPI). The WPI was first published in 1902, and was one of the more important economic indicators available to policy makers until it was replaced by the PPI in 1978. The change to Producer Price Index in 1978 reflected, as much as a name change, a change in focus of this index away from the limited wholesaler-to-retailer transaction to encompass all stages of production. While the WPI is no longer available, the family of producer price indexes provides a close counterpart in the Finished Goods Price Index.

SERVICE

Activities that provide direct satisfaction of wants and needs without the production of tangible products or goods. Like the related term good, a service is produced using society's resources and represents a fundamental aspect of the economy. Limited resources are used to produce the services that satisfy unlimited wants and needs in an ongoing effort to address the problem of scarcity.

This isn't me! What am I?

Mark Twain said "I wonder how much it would take to buy soap buble if there was only one in the world."
"There is a way to look at the past. Don't hide from it. It will not catch you - if you don't repeat it."
