MARKET SHARE: The fraction of an industry's total sales accounted for by a single business. In general, market share is a "first-guess" indicator of a firm's market control. If, for example, a company has a market share of 100 percent (that is, a monopoly), then you can rest assured it has a substantial amount of market control. A company with a 25 percent market share has less, but still notable, market control. In fact, when you get right down to the bottom line, the phrase "market share" is only worth mentioning for oligopolistic firms with a significant degree of market control. There really is no market control for a monopolistically competitive firm with a 0.00000001 percent market share.

PURPLE SMARPHIN
Your compete MICRO*scope for today

You are the type of person who has an exceedingly organized mind, but a somewhat cluttered life. Family and friends worry that some day you will leave home in the morning, deep in thought, and end up in another state. Today, you are likely to spend a great deal of time at an auction trying to buy either storage boxes for your winter clothes or several magazines on time travel. Be on the lookout for crowded shopping malls. You should consider shopping at stores or businesses beginning with the letter T, but do not buy any products with a serial number or product code containing the number 231104. Your preferred shopping venue is the Internet. Your special symbol is the exclamation point (!).


Is this You?

As a Purple Smarphin, you are the brightest and most intelligent person you know. And that goes for shopping, too. You know exactly what you want. You know exactly what it costs. You know exactly when and where to buy. But, of course, shopping is only one of the many activities that attracts your intellectual attention. You shop when you need to and buy if have to, but shopping is not the end all of your life.


This isn't me! What am I?
COLLUSION

A usually secret agreement among competing firms in an industry (primarily oligopoly) to dominate the market, control the market price, and otherwise act like a monopoly. The reason for the secrecy is that such behavior is illegal in the United States under antitrust laws. Collusion can take one of two forms. Explicit collusion occurs when two or more firms in the same industry formally agree to control the market. Implicit collusion occurs when two or more firms in the same industry control the market through informal, interdependent actions. Collusion is one of two ways oligopoly firms cooperate to avoid competition. The other is through mergers.

The Economics Of Dueling POLITICAL VIEWS

There seems to be a disturbance on the steps of the Shady Valley City Hall. Why it's the twins, Donna and Rhonda, engaged in yet another of their long-running, and overly heated, political arguments. Donna, you see, is a devoted Democrat and Rhonda is a rigid Republican. They haven't found much to agree on since, well, come to think of it they've never agreed on anything. In their current debate, Donna is making a strident case for stricter regulation of the banking industry and Rhonda is championing the virtues of free enterprise. I had better hitch up my jogging pants and intervene before their argument comes to blows -- again. While I do, let's ponder the source of differing political views.
