There are two general ways in which the
term "market" is used in economics. First, a market is thought of as a formal or
informal organization of buyers and sellers who conduct trades in particular
commodities or services. The market may be located at a geographical meeting
place, such as your friendly neighborhood bookstore or shopping center (a retail
market). A market may be organized over wide areas connected through phones or
computer terminals. Although the trading room of the New York Stock Exchange is
located in New York City, buyers and sellers who actively participate in this
market may conduct their trades from distant locations. This description is the
institutional way of looking at a market. The second meaning of the word "market" is used in formal economic models. Here the equations that explain the demand and supply of a commodity such as money are sometimes grouped together. The reasons for supplying and holding money are thought to be specific enough to warrant separate equations. This is an abstract way to think of the money market. New financial assets are traded in primary markets. Financial assets that are resold are waded in secondary markets. Firms that specialize in trading either new or reissued financial assets are called primary secondary dealers, respectively. |
