MARKET STRUCTURE: The manner in which a market is organized, based largely on the number of firms in the industry. The four basic market structure models are: perfect competition, monopoly, monopolistic competition, and oligopoly. The primary difference between each is the number of firms on the supply side of a market. Both perfect competition and monopolistic competition have a large number of relatively small firms selling output. Oligopoly has a small number of relatively large firms. And monopoly has a single firm.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who is always ready and willing to help others. Family and friends have no understanding of your inner self, but neither do you. Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway trying to buy either a coffee cup commemorating yesterday or a replacement remote control for your television. Be on the lookout for telephone calls from long-lost relatives. You should consider shopping at stores or businesses beginning with the letter K, but do not buy any products with a serial number or product code containing the number 456851. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).
Is this You?
As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.
This isn't me! What am I?

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.

Scraping Up The POLLUTIONOne of Shady Valley's featured factories is Mona Mallard's Duct Tape Industries. It's the world's leading producer of duct tape -- that shiny, seemingly omnipresent, cloth-like tape that's used for everything EXCEPT ventilation ducts. Mona Mallard's Duct Tape Industries also employs thousands of voting, taxpaying Shady Valley residents. The amount of campaign money, legal and otherwise, contributed by Mona Mallard herself to Shady Valley politicians is, well, incalculable. All of this means that our little pedestrian exploration through the backlot dumping ground of Mona Mallard's Duct Tape Industries main production plant puts us on very, VERY sensitive turf. The reason, of course, is that the duct tape plant has been discarding sticky, toxic, gooey junk onto the ground. This is a potentially hazardous situation, not only because this sticky, toxic, gooey junk appears to be leaking into the Shady Valley River, but because a Mona Mallard's Duct Tape Industries security guard is headed in our direction. Rather than confront this guard, I suggest we spend our time exploring the problems of pollution. RUN!
