_Distribution primarily Functional rather than Personal._--Where men get incomes that are composed of wages, interest, and profits, economic science should, in the first instance, tell us how the rates of wages and interest and the amount of profits are determined. A study of the static laws of distribution concerns itself with the reward of labor as such, and the reward of capital as such, while a study of dynamics takes account of pure profits. When we know what the rates of wages and interest are, we can tell what any capitalist-manager should have by knowing how much capital he furnishes and how much and how well he works as a manager. If the business is yielding a net profit, over and above the interest on its capital, we can tell what part of this net income any one stockholder will get--in the form of a rate of dividends in excess of the rate of interest--if we know how much of the common stock of the company he owns. His personal income depends on the incomes attaching to the functions he performs. The science of distribution should tell us primarily, not what any man personally gets as a total income and how well off he is as compared with other men, but in what way the wages of his labor, the interest on his capital, and the return for the _entrepreneur's_ function are fixed. In technical terms this is saying that distribution is primarily _functional_ and not personal. Certain forces assign certain rewards to different functions which are involved in the creating of wealth, and the science of distribution tells us how these forces work--tells us, in short, how wages, interest, and true profits are, in and of themselves, determined. If any man works and gets wages, that part of his income will be determined by the wages law. If he furnishes capital, a second part of his income will be determined by the interest law. If he also cooerdinates labor and capital, whatever he may thus gain is determined by the law of profit. Economic science has to ascertain and state what these three laws are, though in its static division it has only to account for two of them.
