GRESHAM'S LAW: A principle stating that bad money drives good money out of circulation. For this law to apply an economy clearly needs two types of money, one considered good and the other considered bad. Good and bad money in this context has nothing to do with the propensity to torture small animals or attempts at world domination. Good and bad are based on the official value in exchange versus value in use. Gold and silver, which were both used as money in the U.S. Economy in the 1800s, provides an illustration. Silver took on the role of "bad money" because it was relatively less value in use than gold. As such, people used silver as everyday money and stockpiled, or hoarded, gold. The silver bad money drove the gold good money out of circulation.

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.

[What's This?]

Today, you are likely to spend a great deal of time watching the shopping channel hoping to buy either a T-shirt commemorating last Friday (you know why) or a rotisserie oven that can also toast bread. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
