LRAC CURVE: The common abbreviation for the long-run average cost curve, which is a curve depicting the per unit cost of producing a good or service in the long run when all inputs are variable. The long-run average cost curve can be derived in two ways. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. at different output levels. The more common method, however, is as an envelope of an infinite number of short-run average total cost curves. Such an envelope is base on identifying the point on each short-run average total cost curve that provides the lowest possible average cost for each quantity of output. The long-run average cost curve is U-shaped, reflecting economies of scale (or increasing returns to scale) when negatively-sloped and diseconomies of scale (or decreasing returns to scale) when positively sloped. The minimum point (or range) on the LRAC curve is the minimum efficient scale.

BROWN PRAGMATOX
Your compete MICRO*scope for today

You are the type of person who is always ready and willing to help others. Family and friends occasionally strap large packages to your back for no apparent reason. Today, you are likely to spend a great deal of time searching for a specialty store hoping to buy either a birthday gift for your grandfather or a pleather CD case. Be on the lookout for poorly written technical manuals. You should consider shopping at stores or businesses beginning with the letter H, but do not buy any products with a serial number or product code containing the number 300638. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).


Is this You?

As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.


This isn't me! What am I?
CONSUMER PRICE INDEX

An index of prices of goods and services typically purchased by urban consumers. The Consumer Price Index (CPI) is compiled and published monthly by the Bureau of Labor Statistics (BLS), using price data obtained from an elaborate survey of 25,000 retail outlets and quantity data generated by the Consumer Expenditures Survey. The CPI is one of two key price indexes used as a measure of the price level and to estimate the inflation rate. The other is the GDP price deflator. The CPI is also officially designated as the Consumer Price Index for All Urban Consumers (CPI-U). Another noted price index is the Producer Price Index (PPI).

Fact 2: Our Subjective Values

Upon leaving Scarcity Stan's Bakery Shoppe and Confectionery Palace our pedestrian's excursion drops into Mega-Mart Discount Warehouse Super Center. A quick tour of this mecca of mass production -- lasting no more than three days -- is likely to reveal within the 20 gadzillion square feet of floor space a number of sales racks, shelves, and tables filled with merchandise marked down for clearance. A prominently displayed sign on one sales rack boldly declares that the regular $24.99 price has been drastically reduced, for this week only, to $3.98. What a bargain! What a sale! We have the chance -- "for a limited time only" -- to get stuff valued at $24.99 for only $3.98! With a bargain like this, how can we lose?

It's easy to lose, if you don't understand the concept of value. Most of us have several "bargains" stored away in the attic, closet, or garage that never have seen, and probably never will see, anything resembling use. What seemed like a great "bargain" at the store, does nothing but occupy space at home. (By the way, does anyone have use for a distributor cap for a 1949 Ford?)
