^ 02^ 27 UNDERSTANDING ECONOMICS T^hat is the basic idea of the American eco- ’’ nomic system? The basic idea is called the market principle. We can best illustrate this principle by thinking about a single business transaction. Mrs. Jones goes to a supermarket to-buy groceries. At the bakery counter she sees several kinds of loaves of bread— at different prices. She chooses one and puts it in her cart. After making her other purchases she goes to the checkout counter where a cashier totals her purchases and she pays for them. The store manager didn’t know Mrs. Jones would buy that loaf of bread. Neither did the bakery which sold the bread to the supermarket chain. Nor did the flour-milling firm which sold the flour to the bakery. The same is true of others whose acts led up to Mrs. Jones’ final purchase. None of them knew who would buy the final product in that chain of transactions. What did they know? jp^IRST OF ALL, EACH BUSINESSMAN involved knew ^ there was a “market” for his goods. He knew roughly what quantity he could sell and at what price. He knew there was, in economic terms, a demand for what he had to sell. While he did not necessarily know who would buy his output, he knew there were buyers—and he had a pretty good estimate of the price at which they would be will ing to buy. But the whole chain of transactions was vol untary. Together they brought about an organiza- THE MARKET PRINCIPLE tion of actions which wound up with a new loaf of bread in Mrs. Jones’ kitchen. We call this organiz ing principle the “market system.” One of the main features of this system is that business transactions are voluntary. Buyers, like Mrs. Jones, purchase what they want at prices they are willing to pay. Sellers, like the supermarket, sell the kinds of goods they think buyers will want, at prices which reward them for their services as sup pliers. In other words, the goods which suppliers bring to market are intended to match buyeys’ wants: supply is created to meet demand. —One of a series, based on the discussion course, understanding economics, published by Chamber of Commerce of the United States.
