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.

Production
- The first unit of this lesson, Short-Run Production, begins our study by introducing a few basic concepts underlying production, especially short run, long run, fixed input, and variable input.
- In the second unit, Production Measures, we take a look the three standard measures of production -- total product, average product, and marginal product.
- The third unit, Product Curves, then presents graphical relations for these three measures -- total product curve, average product curve, and marginal product curve.
- In the fourth unit, Long-Run Production, we examine the role returns to scale play in long-run production.
- The fifth and final unit, Supply, then closes this lesson by previewing the importance of production to the supply decisions by firms.s
