MARKETS and MARKET STRUCTURES

Text B

The term market, as used by economists, is an extension of the ancient idea of a market as a place where people gather to buy and sell goods. In former days part of a town was kept as the market or marketplace, and people would travel many kilometres on special market-days in order to buy and sell various commodities.

Today, however, markets such as the world sugar market, the gold market and the cotton market do not need to have any fixed geographical location. Such a market is simply a set of conditions permitting buyers and sellers to work together.

In a free market, competition takes place among sellers of the same commodity, and among those who wish to buy that commodity. Such competition influences the prices prevailing in the market. Prices inevitably fluctuate, and such fluctuations are also affected by current supply and demand.

Whenever people who are willing to sell a commodity contact people who are willing to buy it, a market for that commodity is created. Buyers and sellers may meet in person, or they may communicate in some other way: by telephone or through their agents. In a perfect market, communications are easy, buyers and sellers are numerous and competition is completely free. In a perfect market there can be only one price for any given commodity: the lowest price which sellers will accept and the highest which consumers will pay. There are, however, no really perfect markets, and each commodity market is subject to special conditions. It can be said, however, that the price ruling in a market indicates the point where supply and demand meet.

Although in a perfect marketcompetition is unrestricted and sellers are numerous, free competition and large numbers of sellers are not always available in the real world. In some markets there may only be one seller or a very limited number of sellers. Such a situation is called a monopoly, and may arise from a variety of different causes. It is possible to distinguish in practice four kinds of monopoly.

State planning and central control of the economy often mean that a state government has the monopoly of important goods and services. Some countries have state monopolies in basic commodities like steel and transport, while other countries have monopolies in such comparatively unimportant commodities as matches. Most national authorities monopolize the postal services within their borders.

A different kind of monopoly arises when a country, through geographical and geological circumstances, has control over major natural resources or important services, as for example with Canadian nickel and the Egyptian ownership of the Suez Canal. Such monopolies can be called natural monopolies.

They are very different from legal monopolies, where the law of a country permits certain producers, authors and inventors a full monopoly over the sale of their own products.

These three types of monopoly are distinct from the sole trading opportunities which take place because certain companies have obtained complete control over particular commodities. This action is often called «cornering the market» and is illegal in many countries. In the USA anti-trust laws operate to restrict such activities, while in Britain the Monopolies Commission examines all special arrangements and mergers which might lead to undesirable monopolies.
