COMPETITION AMONG THE FEW: A market with a small number of sellers (or buyers), such that each seller (or buyer) has some degree of market control. Many think of this type of competition when the term competition arises (the other type is competition among the many). This sort of competition leads to intense rivalry where each participant achieves their objective only by beating the others. I call this track-meet competition. In a track race among a handful of competitors, like a 100 meter sprint, the winner is the fastest of THIS GROUP.

ASYMMETRIC INFORMATION

Information is not equally available to everyone. Asymmetric information results because efficient information search inevitably stops short of compete information. Some people obtain more benefits from information than others, are willing to incur higher search costs, and thus end up knowing more. Or they incur lower information search costs and have easier access to the information. In a market, sellers tend to have more information about the good than buyers. Asymmetric information gives rise to adverse selection, moral hazard, and the principal-agent problem. These problems can be lessened through signalling and screening.

[What's This?]

Today, you are likely to spend a great deal of time strolling around a discount warehouse buying club trying to buy either a case of blank recordable DVDs or a pair of red goulashes with shiny buckles. Be on the lookout for defective microphones.
Your Complete Scope

This isn't me! What am I?

Three-forths of the gold mined each year is used to manufacture jewelry.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover."

-- Mark Twain
