LONG-RUN AVERAGE COST CURVE: 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 (usually abbreviated LRAC) 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.

BEIGE MUNDORTLE
Your compete MICRO*scope for today
You are the type of person who pursues life to the moderate because its just too much effort to be extreme. Family and friends call you when they need a flat tire changed, but not when they want to attend the theater. Today, you are likely to spend a great deal of time watching infomercials trying to buy either a solid oak entertainment center or a remote controlled ceiling fan. Be on the lookout for vindictive digital clocks with revenge on their minds. You should consider shopping at stores or businesses beginning with the letter Q, but do not buy any products with a serial number or product code containing the number 124563. Your preferred shopping venue is discount super centers. Your special symbol is the period (.).
Is this You?
As a Beige Mundortle, you are somewhat dull, somewhat boring, somewhat lusterless. You don't particularly care and you don't really care that you don't care. You know that you have a somewhat drab, lackluster life, and that's just fine with you. You shop when you need to, buy what you have to, and get on with your life. It's just another day, another expenditure. You don't really care to spend a lot of time shopping, but you don't really care to spend a lot of time doing much of anything. Life goes on. So what? Who cares?
This isn't me! What am I?

TOTAL VARIABLE COST Cost of production that does change with changes in the quantity of output produced by a firm in the short run. Total variable cost is one part of total cost. The other is total fixed cost. Variable cost depends on the level of output. If a firm produces more output, then variable cost is greater. If a firm produces no output, then variable cost is zero. A cost measure directly related to total variable cost is average variable cost.

Fact 6: Our Unknown EconomyDr. Nova Cain, DDS, has her office in the mini-mall just north of city hall. You know the sort of mini-mall. It has a branch of Interstate OmniBank, Smilin' Ted's All-Comers Insurance Agency, an auto parts store, a branch of the public library, and four chiropractors. Dr. Cain's location near the Shady Valley City Hall is most fortunate. One of my back molars is beginning to shoot sharp pains through my eyeball, into my brain, and out the back of my head. I've been meaning to stop by for a cleaning and check up, but, well, the thought of sharp needles and high-speed drills grinding away large portions of my teeth convinced me that other activities were more important. Now, however, just as we're trying to trek through the complexities of the economy, that back molar has decided to throb incessantly. It's best if I stop in and let the kind and (hopefully) gentle Dr. Cain check it out. Guess what? ROOT CANAL!
