WHOLESALE PRICE INDEX: 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.
