Section CXXII.. Value in Exchange of Money.

Value In Exchange Of Money.

The value in exchange of money is said to be high when all other commodities estimated in money are cheap; and low in the opposite case. We have here to do with the application of the most general of all laws of price; therefore, with the demand and supply of money. The demand for it depends on the wants and the means of payment of its purchasers. Therefore, if a country has little trade, it will, on this account, need only few instruments of trade, that is, of little money to effect exchanges. If it be poor in other goods, it will get little money in exchange. In the former respect, there is a beneficent principle of equalization or compensation which decreases the price-variations of money, no matter of what kind, in the necessity, when the number of business transactions remains the same and money becomes cheaper, to use more of it, and less when it becomes dearer.(741) The supply of money is, in the long run, dependent chiefly on the cost of production. But since the cost of production in different mines is very different, the value in exchange of the precious metals is determined by the cost of producing them from the poorest mines which must be worked in order to supply the aggregate want of them. (See § 110.)(742) The more unfavorable the conditions of their production are, the greater is the quantity of commodities which must be given for a pound of gold, silver etc.; that producers may not be deterred from the prosecution of their work. The extremes of the value in exchange of money are dependent on the use for which it is intended. That value cannot rise higher than to the point at which single pieces of money become inconvenient on account of their smallness, nor sink lower than the point at which a similar inconvenience is produced by their too great size. In both instances, it would become necessary to have recourse to other instruments of exchange.
