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.

AGGREGATE SUPPLY SHIFTS Changes in the aggregate supply determinants shift both the short-run aggregate supply curve and the long-run aggregate supply curve. The mechanism is comparable to that for market supply determinants and market supply. There are two options--an increase in aggregate supply and a decrease in aggregate supply. An increase in resource quantity or quality or a decrease in resource price shifts one or both of the aggregate supply curves to right. A decrease in resource quantity or quality or an increase in resource price shifts one or both of the aggregate supply curves to left.
