In general, we measure utility by the relation between the nature of any object and human nature as expressed in wants. A bushel of wheat has utility equal to the number of loaves of bread it will furnish to hungry humanity. In this respect every bushel may have the same utility as every other. This would be true if every bushel of wheat was wanted by hungry people able to exert themselves in securing it; but if five bushels of wheat are sufficient for each human being in a year’s supply of bread, a distribution to all the world of more than five bushels to each would make some of the wheat useless. So if the world’s product of wheat more than supplies the world’s want, the extra amount will be without utility unless some means of storing against future want is devised. In that case the utility of the stored portion will be lessened by the extra exertion required to store it until the need comes. One may be glad to pay twenty-five cents for a good dinner, but an equally good dinner offered immediately afterwards will have no utility, unless he can save it for supper. If the dinners offered are so many as to imply that several will be useless, the value of each is likely to be affected by this estimate of lost utility in some. Dinners in that case are liable to be furnished for what they are worth for cold suppers. If any article of commerce, like wheat, has its highest utility in one way of meeting wants, as in bread, that utility will have a strong influence upon value as long as the supply of wheat is not too great for this want. If the supply of wheat should be so great that only a small portion could be used for bread, other utilities would be sought. It would be used for feeding hens, and perhaps for cattle feed. If still the amount is too great to be consumed, it might be used for starch. In this case the least useful portion is likely to furnish the estimate of value for the whole. Both the raiser of wheat and the user will consider the lowest use as the probable basis for sale. Before the opening of the Erie canal a farmer in northern Ohio drew a load of wheat twelve miles in hope of a market. The dealer said: “It isn’t worth anything, since nobody has any use for it. If you had a load of sand, I could pay you for that, to fill the mud-hole in front of my store.” Since the utility of some wheat was nothing, the value of all wheat tended to nothing. On the other hand, if wheat is scarce in the community, it will be used only to meet the wants of the delicate or the fastidious, whose comfort and life may depend upon it. In that case its general value will be estimated by its higher utility, whatever other use it is put to. That is called a final utility, which, in any particular case, is the lowest use implied in consuming the supply. And this final utility is the only one influencing the estimate of value.
