We also saw that among the producers of corn there was virtually no waste of energy from competition. Among the paper makers there was a large waste. And in the case of the railroads, the whole capital invested in the rival railroad, as well as the expense of operating it, was probably a total waste. Let us state, then, for a second law of competition: In any given industry the waste due to competition tends to vary directly as the intensity. As an additional example to prove the truth of these laws, take the competition which exists between buyers. In the case of ordinary retail trade the number of buyers is very great, and the competition between them is so moderate that we hardly remember that it exists. It is difficult to see how there could be any waste from this competition among buyers, at least of any amount. Expressed in the language of the laws we have found: The number of competing units is so great that competition is neither intense nor wasteful.

From these two laws and a study of the examples we have given, it is easy to deduce a third. We have seen that when competition became very wasteful, monopoly arose; indeed, we have noted the working of this law all through our investigation. The principal cause assigned for the formation of the linseed-oil trust was the waste which intense competition had caused. The third law is, then: In any given industry the tendency toward the death of competition (monopoly) varies directly with the waste due to competition.

We might now combine these three laws to deduce the fourth law, which is: In any given industry the tendency toward the death of competition (monopoly) varies inversely with the number of competing units. But this law is also proved independently. Look back over all the monopolies we have studied, and it will be seen that one of the most important conditions of their success was the small number of competitors. Fifty men could be brought together and organized, and made to bury their feuds and rivalries, when with a thousand the combination would have been impossible. We have seen, in the case of the farmers, how their great number alone has prevented them from forming combinations to restrict the competition among themselves.

It should be said that these laws, like all other laws of economics, are not to be taken in a narrow mathematical sense. We cannot study causes and effects dependent on the caprice of men's desires and wills with the minute exactness with which we solve numerical problems. Taken in the broad sense, however, the study we have made in the preceding chapters is sufficient proof of their truth.

The common expressions of trade afford still further evidence. We often hear the expression: "A healthy competition." But the very existence of the phrase implies that there may be an unhealthy competition, and if so, what is it? Is it not that competition whose intensity is so great that it causes a large waste of capital and labor in work other than production; whose intensity is so great that, like an animal or a machine working under too great a load, it labors intermittently,—now acting with great intensity and forcing prices far below their normal plane, now pausing in a reaction, when a temporary combination is formed, and allowing prices to spring back as far above the point indicated by the relation of supply and demand; and finally reaching the natural end for unhealthiness—death. In fact, a recent economic writer declares that especially intense competition should be called war, as, indeed, it frequently is called, rather than competition.

Looking about us for other causes of variation in the intensity of competition we discover a fifth law: The intensity of competition tends to vary directly in proportion to the amount of capital required for the operation of each competing unit, especially when the interest on the capital invested forms a large proportion of the cost of production. Take, for example, the case of a railway line. All the capital invested in it is wasted unless the road is in operation. Hence it will be better to operate the road, so long as receipts are any thing more than the expense of operation, than to abandon it. An enterprise in which no capital is invested will cease operations when receipts do not exceed its expenditure and there is no prospect of betterment. But in the total expense of operating a railroad, a large item is the interest on the capital invested, which is as truly a part of the total cost of carrying the traffic as is the daily labor expended in keeping the road in good repair. (In railway bookkeeping only an arbitrary line can ever be drawn between capital account and operating expenses.) Now, in order to pay operating expenses and fixed charges, railways must secure traffic. We suppose that they are doing this by competition, and that they have not yet combined to form a monopoly. Let us suppose that this competition cuts down receipts to a point where they are just sufficient to pay the whole cost of carriage. In an enterprise in which no capital was invested some of the competitors would be sure to fall out when profits disappeared; but here there is no such chance of relief; and though the competition keeps on until the receipts are only enough to pay the operating expenses, still the road is not abandoned because then the capital invested, in it would be a complete loss. Changes in productive processes often lessen the demand for a line of goods; but the owners of the capital invested in factories and machines for making these goods may often cause them to be continued in operation at a loss rather than lose all that they have invested, and because they hope for better days and a renewal of the demand.

For the sixth law of competition we have: In any given industry the tendency toward the death of competition (monopoly) varies directly with the amount of capital required for each competing unit. This law is proven in part by the preceding laws; for when a large capital is required for each competing unit, the number of competitors will be small and the tendency toward monopoly will be strong; but it may also be proven independently. Business men, before they form a combination, are certain to ask whether new competitors are likely to enter the field against the combination. Now, as we have seen in very many cases in the preceding chapters, when there is a great amount of capital required, new competitors will be very unlikely to enter the field. If there is but little capital required, they will be very apt to do so, being tempted by the prospect of large profits at the monopoly's prices. But they know that the combination will concentrate its strength to fight them in every way; and if they must invest a great deal of money in buildings, plant, etc., to start operations, they will be apt to think twice before they take the field against the combination.

The seventh law of competition is: In any given industry in which natural agents are necessary, the tendency toward the inequality of competition (monopoly) tends to vary directly with the scarcity of available like natural agents.

The influence of limited natural agents in promoting the growth of monopolies is a matter of the greatest importance. That the law is true, is evident upon slight investigation. For if some especial gift of Nature is a necessity to any industry, and those who are engaged in that industry can secure all the available gifts of Nature of that sort, there is no opportunity for new competitors to enter the field.

It is to be noted that in this seventh law we have used in apposition with the term monopoly, the term "inequality of competition" instead of "death of competition," as in the preceding laws. We are now in need of a definition of the term monopoly. Webster defines it as "the sole control over the sale of any line of goods"; Prof. Newcomb says "a monopoly is the ownership or command by one or a limited number of persons of some requisite of production which is not solely a product of human labor"; Sturtevant says "a monopoly is such a control of the supply of any desirable object as will enable the holder to determine its price without appeal to competition." To the first definition we object that it is both narrow and indefinite. The second seems to omit such important classes of monopolies as the combinations to limit competition; and Sturtevant's definition is unscientific in this: Hardly any monopoly exists whose holders can without limit determine the price of its product. If the price continues to rise, competition in some form will appear. Take, for example, the business of transporting goods from New York to San Francisco; if all the railway lines combine to form a monopoly, the competition of ocean steamers via Panama would eventually stop the rise in rates, if no other outside competition stopped it before. The owners of a rich mine have a real monopoly, though they cannot raise the price above a certain point without being undersold by the owners of poorer mines or those more remote from market. Consideration of these facts lead us to construct the following definition: A monopoly in any industry consists in the control of some advantage over existing or possible competitors by which greater profits can be secured than these competitors can make. For the law of monopolies we have: The degree of a monopoly depends upon the amount of advantage which is held over existing or possible competitors. When the advantage of the monopoly is so great that no other competitor will try to do business in competition with it, we may rightly say that competition is dead. The great share of the monopolies which are based on this seventh law of competition, those due to the control of natural agents, only restrict competition by the attainment of an advantage over their competitors, and do not destroy it.
