MARGINAL COST: The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost indicates how much total cost changes for a give change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (remember total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. Marginal cost, usually abbreviated MC, is found by dividing the change in total cost (or total variable cost) by the change in output.

BEIGE MUNDORTLE
Your compete MICRO*scope for today

You are the type of person who could be mistaken for a piece of furniture or perhaps a rock. Family and friends do not seek out your advice on fashion, politics, the economy, computer technology, or much of anything else. Today, you are likely to spend a great deal of time lost in your local discount super center trying to buy either a video game player or an AC adapter that won't fry your computer. Be on the lookout for florescent light bulbs that hum folk songs from the sixties. You should consider shopping at stores or businesses beginning with the letter R, but do not buy any products with a serial number or product code containing the number 573906. 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?
DISCOUNT RATE

The interest rate charged by the Federal Reserve System (the Fed) for loans to commercial banks, which in principle can be used as a means of a controlling the money supply. An increase in the money supply can be achieved when the Fed lowers the discount rate. A decrease in the money supply can be achieved when the Fed raises the discount rate. The discount rate, which is set by Federal Reserve Banks, subject to approval by the Board of Governors, is used more to signal changes in monetary policy rather than to actually control the money supply. The discount rate is one of the three monetary policy tools that the Fed can use, in principle, to control the money supply. The other two are open market operations and reserve requirements.

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?)
