In America as towns or villages appeared where some men could give most of their time to producing something besides food, local markets sprang up whither farmers came to ex change with village artisans. Every little country store in America is in some measure a market, where the merchant trades with the farmer, the townpeople with the merchant, and neighbors with each other. The larger cities become the great markets, toward which are sent all the surplus products of farms and of the mills in smaller cities to be distributed to the consumers.
§ 13. Communication and markets. Buyers and sellers need not be physically present at one place, but they must be in communication, so that there can be a common understand ing between them. In earlier times, however, there were no easy means of gathering information such as trade bulletins, newspapers, special commercial agencies, and no rapid means of transmitting intelligence, such as the steamship, the rail road, the postal service, the land telegraph, the ocean cable, and the wireless telegraph. The traders once had to be to gether at one place in order that each should know what the others were willing to do. All this is now changed and for
many purposes men in Paris, in New York, in London, and in Calcutta are separated by only a few moments for trading.
As a result of these changes, the old periodical fairs and markets have almost disappeared, and there has been a widen ing of the village-market to the markets of the province, of the nation, and finally of the world. While a part of every one's purchases continues to be made in the neighborhood, a greater and greater portion of the total business is done by traders that are widely separated and that are members of a world-market. Various products produced in the same locality may seek different markets. While the market for fruit and eggs may be in the village near the farmhouse, that for most of the wheat of the same farm may be in Liverpool.
§ 14. One price in a market. If the many buyers and sellers coming together at a market-place were to meet as isolated couples, without knowledge of the others, the trades would be made at a great variety of ratios, possibly no two trades at the same. But the coming together of buyers and sellers into a single trading group has a remarkable effect on the ratio at which the trades take place between individual buyers and sellers. So far as there is truly a meeting of minds,. all the trades taking place at any one time are at the same ratio. It is the essential proof of a true market that there is but one price at any moment. A complete or typical market may therefore be defined as a group of closely com municating traders whose valuations, however diverse before they meet, unite for a moment into a single price (as regards the goods actually traded). A typical market exists and a market price results when there is : (a) a group of buyers and sellers; (b) a judgment by each trader of both groups, as to the conditions of the market; (c) free bidding on both sides.
§ 15. Imperfect market conditions. When, however, these conditions are not fulfilled perfectly, different prices may exist at the same moment near each other. Retail and wholesale merchants may be purchasing goods in the same room at the same time at very different prices, but there are here two dis tinct and well recognized markets. Even within what is ordi narily the same market, differences may for brief times exist. On the occasion of a break in stocks, excited traders within ten feet of each other make bids that differ by thousands of dol lars; but the expression used to describe this explains the cause : "the market has all gone to pieces." The very essence of the idea of market is the meeting of minds in agreement on a price. Within a group of buyers and sellers thus meet ing, one price prevails at least for the moment. The more nearly the actual conditions approach to the ideal of a market, the less are prices fixed by individual higgling, and the more impersonal they become, the buyers and sellers being compelled to adjust their bids to the needs of the market, and being un able to vary them greatly one way or the other.
