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.

Lesson 3: Scarcity | Unit 4: College Cost
|
Page: 12 of 17
|
An example of the opportunity cost of attending college.- Tuition, fees, textbooks, sliderule, etc. ($932.71 per semester) is an explicit opportunity cost.
- The opportunity cost is all other things that you could have bought with this money-fuzzy dice, hot fudge sundaes, a used Ford Pinto, music CDs.
- The tuition cost of your college degree is the added up over all semesters ($7,461,68).
However, the TOTAL COST actually goes well beyond this explicit $7,461,68 payment, since there are other costs that don't involve a money payment:- By attending school you have foregone alternative activities like working.
- Unearned income, $15,000 per year, $60,000 for four years, is an extremely important implicit opportunity cost of a college education.
- Implicit opportunity costs need not have a dollar value attached.
- The foregone satisfaction from activities like watching television or sleeping, are also implicit opportunity costs.

DEADWEIGHT LOSS The decrease in the sum of consumer surplus and producer surplus that results from the imposition of a tax. When a tax drives a wedge between demand price and supply price it disrupts what otherwise would be an efficient market equilibrium. Inefficiency arises because while a portion of the sum of consumer and producer surplus is merely transferred to government, a portion of this sum also disappears. The part that disappears is the deadweight loss and is an indicator of the inefficiency of the tax.
