1. Monopoly gets its power from political, economic, and commercial sources. A political monopoly derives its power of control from a special grant from the government, forbidding others to engage in that business. The typical political monopoly is that conferred by a crown patent bestowing the exclusive right to carry on a certain business. A second kind is that conferred by a patent for invention, or the copyright on books, the object of which is to stimulate invention,, research, and writing by giving the full control and protection of the government to the inventor and writer or their assignees. In this case the privilege is socially earned by the monopolist; it is not gotten for nothing. Moreover, the patent is limited in time, expires and becomes a social possession. A third kind is a government monopoly for purposes of revenue. In France, the government controls the tobacco trade, and the high price charged for tobacco makes the monopoly yield a large income. A fourth kind are public franchises for public service, as street-railways, lights, gas, waterworks, etc. These are granted to private capitalists to induce them to invest capital in something which has public utility.

The sources of monopoly power.

Political monopoly.

Economic monopoly.

Economic monopoly arises when the ownership of scarce natural agents, as mines, land, water-power, comes under the control of one man or one group of men who agree on a price. Economic monopoly is a result of private property that is undesigned by the government or by society. It is exceptional, considering the whole range of private property, but it is important. The oil-wells embracing the main sources of the world's supply have come under one control. One corporation may control so many of the richest iron-mines of the country as to be able to fix a price different from that which would result under competition. Coal-mines, especially those of some peculiar and limited kind, such as anthracite, appear to become easily an object of monopolization. Economic monopoly merges into political monopolies, such as patents and franchises. Private property is a political institution designed to further social welfare, and only rarely is any particular property a monopoly. Private control of great natural resources doubtless would have been prohibited had it been foreseen.

Commercial monopoly.

Commercial monopoly, variously called contractual, organized, or capitalistic monopoly, arises where men unite their wealth to control a market, to overpower or intimidate opposition, and to keep out or limit competition by the mere Magnitude of their wealth. These various kinds so merge into each other that they cannot always be distinguished in practice. A patent may help a capitalistic monopoly in getting control of a market; great wealth may enable a company to get control of rare natural resources.

2. Monopolies may, for special purposes, be classified also as selling and buying, producing and trading, lasting and temporary, general and local. The terms selling and buying monopoly explain themselves, though the latter conflicts with the etymology. Under conditions of barter the selling and the buying monopoly would be the same thing in two aspects. A selling monopoly is by far the more common, but a buying monopoly may be connected with it. A large oil-refining corporation that sells most of the product may by various methods succeed in driving out the competitors who would buy the crude oil. It thus becomes practically the only outlet for the oil product, and the owners of the land thus must share their ownership with the buying monopoly by accepting, within certain limits, the price it fixes. The Hudson Bay Company, dealing in furs, had practically this sort of power in North America. Many instances can be found, yet, relatively to the selling monopolies, those of the buying kind are rare. A producing monopoly is one controlling the manufacture or the source of supply of an article; a trading monopoly is one controlling the avenues of commerce between the source and the consumers. Monopolies are lasting or temporary, according to the duration of control. By far the larger number are of the temporary sort, because high prices strongly stimulate efforts to develop other sources of supply. Yet the average profits of a monopoly may be large throughout a succession of periods of high and low prices. Monopolies are general or local, according to the extent of territory where their power is felt. At its maximum where transportation and other costs most effectually shut out competition, monopoly power shades off to zero on the border-line of competitive territory.

Special classes of monopoly.

3. Degrees of power to affect price result from varying extent of control; monopoly is a relative term. The term monopoly by its derivation has reference to a single seller; but there are other thoughts in the concept. Monopoly has reference also to the amount of the supply controlled. The frequent use of the adjectives partial, limited, and virtual are implied but usually superfluous recognitions of the relative character of monopoly. Ownership of a particular knife, pencil, book, makes one the unique seller of it, but confers no monopoly power, as the power of substitution is practically absolute; the welfare of no one depends in any appreciable measure on that, particular pencil. Ownership of an important fraction of an entire species of goods gives more power to affect value. One owning a large part of the desirable building sites or houses in town may gain by occasionally letting one stand vacant in order to drive better bargains with tenants. A trade-union may control most of the labor-supply of one kind in a town. But the test of monopoly is that a gain results from a higher price and fewer sales. It begins at the point where there is a motive to limit the supply in accordance with the paradox of value. The control of an entire species of goods gives price-fixing power, limited only by substitution of goods. Even though one person controlled all the coal and wood in any market, their prices still would be limited. If there were but one possible source of meat-supply, most people could live without meat. The monopoly of great species of goods can thus be seen gradually to merge from one grade into another. It is a matter of quality as well as quantity. There is more or less of it in the different industries, and, as noted in the preceding paragraph, it varies over time and territory.
