DECREASING-COST INDUSTRY: A perfectly competitive industry with a negatively-sloped long-run industry supply curve that results because expansion of the industry causes lower production cost and resource prices. For a decreasing-cost industry the entry of new firms, prompted by an increase in demand, causes the long-run average supply curve of each firm to shift downward, which decreases the minimum efficient scale of production.

ORANGE REBELOON
Your compete MICRO*scope for today

You are the type of person who takes great pride in being different, in being a contrarian, in being unlike everyone else. Family and friends no longer accompany you when shopping due to constant bickering with the store clerks. Today, you are likely to spend a great deal of time calling an endless list of 800 numbers hoping to buy either a velvet painting of Elvis Presley or a wall poster commemorating yesterday. Be on the lookout for strangers with large satchels of used undergarments. You should consider shopping at stores or businesses beginning with the letter U, but do not buy any products with a serial number or product code containing the number 393863. Your preferred shopping venue is flea markets. Your special symbol is the backslash (\).


Is this You?

As an Orange Rebeloon, you are very much the rebel and the contrarian. It is your nature to go against the grain. When everyone else is buying, you sell. When everyone else is selling, you buy. You go against the trends. You disdain fashion. If it's hot, you're not. You would march to your own drummer and dance to your own tune, if doing so wasn't so trite and conventional.


This isn't me! What am I?
KINKED-DEMAND CURVE ANALYSIS

An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.

Conserving Our NATURAL RESOURCES

Mona Mallard Duct Tape Industries, the world's a leading producer of duct tape (that all-purpose, omni-present, shiny gray tape), is located right here in Shady Valley. Perhaps you've heard that they recently developed a new-fangled form of duct tape that's certain to revolutionize duct tape as we know it. This revolutionary development has, however, created a "situation" that we, pedestrian explorers of the economy, should consider. Mona Mallard's new duct tape uses "quagliminium," a relatively limited mineral found only in the quaint and courteous Republic of Northwest Queoldiola. Prior to this duct tape development, quagliminium had only one use, as lubricant for OmniStraight shoestring straighteners. The Northwest Queoldiolan supplies were sufficient to lubricate shoestring straighteners well into the year 3000. As a duct tape input, though, quagliminium deposits will be exhausted in a scant 50 years. Should we, could we, allow Mona Mallard to exhaust the supply of quagliminium? If they do, how will future generations lubricate their shoestring straighteners? Should we call for a moratorium on quagliminium use?
