HERFINDAHL INDEX: A measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

BEIGE MUNDORTLE
Your compete MICRO*scope for today
You are the type of person who is a little bit dull, a little bit boring, a little bit lusterless, a little bit unexciting, but otherwise likeable. Family and friends often forget your birthday, your telephone number, your address, and whether or not you actually exist. Today, you are likely to spend a great deal of time at a flea market looking to buy either a how-to book on meeting people or clothing for your pet iguana. Be on the lookout for pencil sharpeners with an attitude. You should consider shopping at stores or businesses beginning with the letter V, but do not buy any products with a serial number or product code containing the number 226135. 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?

PERFECT COMPETITION, REALISM Perfect competition is an idealized market structure that does NOT exist in the real world. While some real world industries might come relatively close to one or two of the four key characteristics of perfect competition, none matches all four sufficiently that they can be declared PERFECTLY competitively. Some industries come close on the large number of small firms and the identical product characteristics. A few industries have relatively good, although not perfect, information about prices and technology. However, almost all industries fall far short of the perfect mobility characteristics.

Stealing A Few Moments For CRIMELike most consumers, workers, and taxpayers, I engage in market exchanges for a lot of stuff -- food, labor, shelter, entertainment, confectionery products. But as I wandered through the peaceful community of Shady Valley, U. S. of A., I entered a "market" that I would have rather avoided. That's right, as the title indicates, I exchange some crime. I was mugged -- relieved of several valuable possessions -- right in front of the Shady Valley police station. I did the selling and my mugger did the "buying." While my part in the exchange was involuntary, the mugger's part was quite voluntary. In fact, the perpetrator of this crime acted much like any consumer headed to Natural Ned's Nursery and Garden Center in search of a creeping juniper. Let's see why?
