§ 2. Conditions of Value: Utility, Difficulty of Attainment, and Transferableness.

That a thing may have any value in exchange, two conditions are necessary. 1. It must be of some use; that is (as already explained), it must conduce to some purpose, satisfy some desire. No one will pay a price, or part with anything which serves some of his purposes, to obtain a thing which serves none of them. 2. But, secondly, the thing must not only have some utility, there must also be some difficulty in its attainment.

The question is one as to the conditions essential to the existence of any value. Very justly Cairnes199adds also a third condition, “the possibility of transferring the possession of the articles which are the subject of the exchange.” For instance, a cargo of wheat at the bottom of the sea has value in use and difficulty of attainment, but it is not transferable. Jevons (following J. B. Say) maintains that “value depends entirely on utility.” If utility means the power to satisfy a desire, things which merely have utility and no difficulty of attainment could have no exchange value.200F. A. Walker201believes that “value depends wholly on the relation between demand and supply.” Carey202holds that value depends merely on the cost of reproduction of the given article. Roscher203finds that exchange value is “based on a combination of value in use with cost value.” Cherbuliez204calls the conditions of value two, “the ability to give satisfaction, and inability of attainment without effort. The first element is subjective; it is determined wholly by the needs or desires of the parties to the exchange. The second is objective; it depends upon material considerations, which are the conditions of the existence of the thing, and upon which the needs of the persons exchanging have no influence whatever.” It is, as usual, one of Cherbuliez's clear expositions. A. L. Perry205states that, “while value always takes its rise in the desires of men, it is never realized except through the efforts of men, and through these efforts as mutually exchanged.”

[pg 253]

The difficulty of attainment which determines value is not always the same kind of difficulty: (1.) It sometimes consists in an absolute limitation of the supply. There are things of which it is physically impossible to increase the quantity beyond certain narrow limits. Such are those wines which can be grown only in peculiar circumstances of soil, climate, and exposure. Such also are ancient sculptures; pictures by the old masters; rare books or coins, or other articles of antiquarian curiosity. Among such may also be reckoned houses and building-ground, in a town of definite extent.

De Quincey206has presented some ingenious diagrams to represent the operations of the two constituents of value in each of the three following cases: U represents the power of the article to satisfy some desire, and D difficulty of attainment. In the first case, exchange value is not hindered by D from going up to any height, and so it rises and falls entirely according to the force of U. D being practically infinite, the horizontal line, exchange value, is not kept down by D, but it rises just as far as U, the desires of purchasers, may carry it.

(2.) But there is another category (embracing the majority of all things that are bought and sold), in which the obstacle to attainment consists only in the labor and expense requisite to produce the commodity. Without a certain labor and expense it can not be had; but, when any one is willing to incur these, there needs be no limit to the multiplication of the product. If there were laborers enough and machinery enough, cottons, woolens, or linens might be produced by thousands of yards for every single yard now manufactured.

In case (2) the horizontal line, representing exchange value, follows the force of D entirely. The utility of the article is very great, but the value is only limited by the difficulty of obtaining it. So far as U is concerned, exchange value can go up a great distance, but will go no higher than the point where the article can be [pg 254] obtained. The dotted lines underneath the horizontal line indicate that the exchange value of articles in this class tend to fall in value.

(3.) There is a third case, intermediate between the two preceding, and rather more complex, which I shall at present merely indicate, but the importance of which in political economy is extremely great. There are commodities which can be multiplied to an indefinite extent by labor and expenditure, but not by a fixed amount of labor and expenditure. Only a limited quantity can be produced at a given cost; if more is wanted, it must be produced at a greater cost. To this class, as has been often repeated, agricultural produce belongs, and generally all the rude produce of the earth; and this peculiarity is a source of very important consequences; one of which is the necessity of a limit to population; and another, the payment of rent.

In case (3) articles like agricultural produce have a very great power to satisfy desires, and if scarce would have a high value. So far as U is concerned, here also, as in case (2), exchange value might mount upward to almost any height, but it can go no higher than D permits. In commodities of this class, affected by the law of diminishing returns, the tendency is for D to increase, and so for exchange value to rise, as indicated by the dotted lines above that of the exchange value.
