VARIABLE INPUT: An input whose quantity can be changed in the time period under consideration. This should be immediately compared and contrasted with fixed input. The most common example of a variable input is labor. A variable input provides the extra inputs that a firm needs to expand short-run production. In contrast, a fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive. This is, by the way, the law of diminishing marginal returns.

Fact 2: Our Subjective ValuesUpon 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?)
