_Effects of Monopoly on the Spirit of Enterprise._--In monopolies, theoretically, there is the same inducement to adopt inventions as in the case of competing firms, excepting always the motive of self-preservation. The monopoly can make money by improvements as competing firms would do. A perfectly intelligent monopoly, with disinterested management, would adopt an improvement offered to it as promptly as any competing firm, if the sole motive were profit. There is no reason why an intelligent monopoly should hold on to antiquated machinery, when modern machinery would enable it to stand the cost of introduction and make a net improvement besides. A competing producer gains an advantage over his rivals by discarding old machinery and adopting new at exactly the right time, neither too late nor too early. The true point of abandonment of the old machine, as we have already seen, is reached when the labor and capital that now work in connection with it can make a shade more by casting it off and making a combination of a better kind; and this rule applies to monopolies as well as to competitors. At just the point where a competitor can gain an advantage over rivals by modernizing his appliances, the monopoly can make money by doing so. An important fact is that the monopoly has as a motive the making of profits for its stockholders. Not only is that a less powerful motive than self-preservation, but it appeals largely to persons who are not themselves in control of the business. Absentee ownership is the chief disability of the monopoly. Managers may have other interests than those of large dividend making, and in such cases a monopoly is apt to wait too long before changing its appliances. It needs to be in no hurry to buy a new invention, and it can make delay and tire out a patentee, in order to make good terms with him; and this practice affords little encouragement to the independent inventor. On the whole, a genuine and perfectly secure monopoly would mean a certain degree of stagnation where progress until now has been rapid.
