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.

INFORMATION

The transfer of knowledge from one person to another. Information is a flow concept. It requires someone (or something) to do the sending and someone to do the receiving. Information is a valuable commodity that provides benefits, but also incurs an opportunity cost to produce, meaning information is never perfect or complete. The existence of asymmetric information (some have more information than others) gives rise to the problems of adverse selection, moral hazard, and the principal-agent problem.

In the Middle Ages, pepper was used for bartering, and it was often more valuable and stable in value than gold.
