PPI: The abbreviation for Producer Price Index, which is an index of the prices domestic producers receive from selling their output. THE Producer Price Index is actually one of several producer price indexes compiled and published monthly by the Bureau of Labor Statistics (BLS). THE Producer Price Index reported regularly in the media is actually the Producer Price Index for All Commodities. Other members in the family of producer price indexes include an array of broad, composite indexes (including finished consumer goods, capital goods, and crude materials); indexes that track the prices received by producers in virtually every major production industry in the country (including lumber, iron and steel, household furniture, and passenger cars); and price indexes for thousands of specific products. In total, the producer price index family includes well over 10,000 separate indexes.

LONG-RUN AVERAGE COST CURVE, DERIVATION

The long-run average cost curve is the envelope of an infinite number of short-run average total cost curves, with each short-run average total cost curve tangent to, or just touching, the long-run average cost curve at a single point corresponding to a single output quantity. The key to the derivation of the long-run average cost curve is that each short-run average total cost curve is constructed based on a given amount of the fixed input, usually capital. As such, when the quantity of the fixed input changes, the short-run average total cost curve shifts to a new location.
