CONCLUDING REMARKS ON THE THREE BRANCHES OF INCOME.

SECTION CXCVII.

INFLUENCE OF THE BRANCHES OF INCOME ON THE PRICE OF COMMODITIES.

We have seen, § 106, that the cost of production of a commodity, considered from the point of view of individual economy, may be reduced to the payment for the use of the requisite productive forces rented or loaned to the producer. Hence every great variation in the relation of the three branches of income to one another must produce a corresponding variation in the price of commodities.[197-1] When, for instance, the rate of wages increases because they absorb a larger part of the national income, those commodities in the production of which human labor, directly employed, is the chief factor, must become dearer as compared with others. Whether this difference shall be felt principally by the products of nature or of capital (compare § 46 seq.), depends on the causes which brought about the enhancement of the rate of wages. Thus, a large decrease of population, or emigration on a large scale, will usually lower rent as well as the rate of interest;[197-2] an extraordinary improvement made in the art of agriculture, only the former; and an extraordinary increase of capital, only the latter. The usual course of things, namely that the growth of population necessitates a heavier draft on the resources of the soil, and thus causes rents to go up, and makes labor dear, must have the effect of raising the price of the products of labor and of natural forces, as compared with the products of capital; and all the more as it causes the rate of interest to suffer a positive decline. The products of mechanical labor become relatively cheaper; and cheaper in proportion as the producing machinery is more durable; therefore in proportion as, in the price of the services it renders, mere interest preponderates over compensation for its wear and tear.[197-3]

Let us, for a moment, leave ground-rent out of the question entirely, and suppose a nation's economy whose production is conducted by eleven undertakers employed on different commodities. Let us suppose that undertaker No. 1 uses machinery exclusively and employs only as many workmen as are strictly necessary to look after it, that undertaker No. 2 has a somewhat larger number of workmen and a somewhat smaller amount of fixed capital, etc.; and that this increase in the number of workmen and decrease in the amount of fixed capital continues until we reach undertaker No. 11, who employs all his capital in the payment of wages. If now, the rate of wages were to rise, and the interest on capital to fall in the same proportion, the commodities produced by undertaker No. 11 would rise most in price, and those of No. 1 decline most. In the case of undertaker No. 6, the opposing influences would probably balance each other, and if the producers of money belonged to this sixth class, it would be very easy to get a view of the whole change in the circumstances of production, in the money-price of the different commodities.[197-4]
