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.

DEMAND SHOCK: A disruption of market equilibrium (that is, a market adjustment) caused by a change in a demand determinant and a shift of the demand curve. A demand shock can take one of two forms--an Demand Increase or a Demand Decrease. An increase in demand is seen as a rightward shift of the demand curve and results in an increase in equilibrium quantity and an increase in equilibrium price. A decrease in demand is a leftward shift of the demand curve and results in a decrease in equilibrium quantity and a decrease in equilibrium price.

MARGINAL COST

The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. It is found by dividing the change in total cost (or total variable cost) by the change in output. Marginal cost is one of four cost concepts used in short-run production analysis. The other three are average total cost, average fixed cost, and average variable cost.
