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.

  • A trough is the turning point between a contraction and an expansion.
  • A trough is the lowest level reached by the economy before an expansion begins, the dark before the dawn.
  • Turning points are important because they are the transition from bad to good of good to bad.
  • A turning point might not be identified until well after it has happened.

BARTER ECONOMY

An economy that trades goods and services predominately using barter exchanges rather than money. Barter economies predated the invention of money, emerging out the early stage of self-sufficiency before giving way to the use of commodity money. However, barter economies occasionally surface in modern times, especially when the public loses confidence in the monetary unit during a government crises or a period of hyperinflation.

[What's This?]

Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway hoping to buy either a large, stuffed kitty cat or a cross-cut paper shredder. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
