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.

VERIFICATION

The hypothesis-testing step of the scientific method in which the hypothesized implication of a theory is compared against real world events and data. This verification can provide support or refutation of the hypothesis. Enough support enables a hypothesis to become a principle. Refutation calls into question the theory implying the hypothesis. In either event, further analysis is indicated.
