OLIGOPOLY, CONCENTRATION: Oligopoly is a market structure that contains a small number of relatively large firms, meaning oligopoly markets tend to be concentrated. A small number of large firms account for a majority of total output. Concentration unto itself is not necessarily bad, but it often leads to inefficient behavior, such as collusion and nonprice competition. Concentration is measured in three ways--market share, concentration ratio, Herfindahl index.

PURPLE SMARPHIN
Your compete MICRO*scope for today
You are the type of person who thinks of shopping as a necessity, but not the most important thing that you will do today. Family and friends treat you as a walking encyclopedia, which is okay with you. Today, you are likely to spend a great deal of time flipping through the yellow pages trying to buy either a remote controlled World War I bi-plane or a wall poster commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for malfunctioning pocket calculators. You should consider shopping at stores or businesses beginning with the letter J, but do not buy any products with a serial number or product code containing the number 589009. 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?

ASSUMPTION An initial condition or statement of a model or theory that sets the stage for an analysis by abstracting from the real world. Assumptions are important to economic analysis. Some assumptions are used to simplify a complex analysis into more easily manageable parts. Other assumptions are used as control conditions that are subsequently changed to evaluate the consequences.

Laying The Groundrules On REGULATIONOur journey has brought us to the "Rs," which means, among other things, that my feet are trifle bit sore. Fortunately, we've also found ourselves at the front door of the Good Time Pharmacy. (Isn't coincidence wonderful?) My quick shopping trip for a pair of cushioned insoles, analgesic rub, and an ankle wrap is lengthened, however, by crossing paths with the normally quiet Stella von Steincamp. Stella, the pharmacist and proprietor of the Good Time Pharmacy, has taken the opportunity of our meeting to voice a rather vehement complaint over a new Shady Valley city government pharmaceutical regulation mandating the use of disposable rubber gloves when preparing and dispensing medicine. She is livid! Her primary complaint (among several) is that the cost of this regulation will send her pharmacy onto a short path into bankruptcy. In the interest of maintaining pharmaceutical services for the residents of Shady Valley, I think, would should explore this topic of government regulation.
