ZERO-SUM GAME: A situation in which a fixed amount is divided up among the winners and losers. In a zero-sum game the wins equal the losses. Many stock market, or financial market, exchanges are zero-sum. One person buys low and sells high, while another buys high and sells low. The wealth in such transactions are merely transferred from one person to another. "Productive" market transactions, in contrast, are not zero-sum. The act of producing goods and services from resources that are consumed to satisfy wants and needs results in a net gain to society.

KINKED-DEMAND CURVE ANALYSIS

An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.

The Wide, Wide World Of FOREIGN TRADE

Two blocks directly south of the Mega-Mart Discount Emporium we'll find that Natural Ned's Nursery and Garden Center is having a grand opening celebration. I'd like to saunter over to check out their sundials -- a valuable, and long sought after acquisition for my backyard garden. In fact, Natural Ned's Nursery and Garden Center has a new shipment of sundials imported from the sundial capital of the world -- the Republic of Northwest Queoldiola. If I'm going to get a sundial, I should get the best, right? Northwest Queoldiola produces the finest, least expensive, and most technologically advanced sundials in the world. However, Mega-Mart Discount Warehouse Super Center has an ample supply of good old American-made sundials. They're a little more expensive and not quite as good, but they're made in the U. S. of A. by good old Americans. What a dilemma!

BLUE PLACIDOLA
[What's This?]

Today, you are likely to spend a great deal of time at a flea market looking to buy either 500 feet of telephone cable or a package of 4 by 6 index cards, the ones with lines. Be on the lookout for crowded shopping malls.

This isn't me! What am I?

Junk bonds are so called because they have a better than 50% chance of default, carrying a Standard & Poor's rating of CC or lower.
