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.

We can use production possibilities to illustrate unemployment, too.- Unemployment is the condition that exists when some available resources are NOT engaged in the production of goods and services.
- Unemployment is interpreted as any bundle that places the economy INSIDE the production possibilities curve.
- With unemployment we don't get as much production as with full employment.
- Unemployment is as any bundle, such as L, inside the curve.
- M is not attainable.
- Unemployment applies to all types of resources.

AGGREGATE DEMAND The total real expenditures on final goods and services produced in the domestic economy that buyers are willing and able to undertake at different price levels, during a given time period (usually a year). Aggregate demand, usually abbreviated AD, is an inverse relation between price level and aggregate expenditures. This is one half of the AS-AD (aggregate market) analysis. The other half is aggregate supply. Aggregate demand consists of four aggregate expenditures--consumption expenditures, investment expenditures, government purchases, and net exports--made by the four macroeconomic sectors--household, business, government, and foreign.
