PLASTIC MONEY: A slang phrase for credit cards, especially when such cards used to make purchases. The "plastic" portion of this term refers to the plastic construction of credit cards, as opposed to paper and metal of currency. The "money" portion is an erroneous reference to credit cards as a form of money, which they are not. Although credit cards do facilitate transactions, because they are a liability rather than an asset, they are not money and not part of the economy's money supply.

MONOPOLISTIC COMPETITION, LONG-RUN ADJUSTMENT

A monopolistically competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each monopolistically competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminate economic profit or economic loss. The end result of this long-run adjustment is two equilibrium conditions--one for profit maximization, the other for zero economic profit.
