proceeds to develop its different functions from the different aspects of the exchange of commodities. Money is used, he says, for two principal purposes: for the payment of debts and for the purchase of what one needs; the two together form “ready money demands.” The state of trade and industry, the mode of living, the customary expenditures of the people, taken all together regulate and determine the volume of “ready money demands,” i. e. the number of “alienations.” In order to effect this multitude of payments, a certain proportion of money is required. This proportion may increase or decrease according to circumstances, even while the number of alienations remains the same. At any rate, the circulation of a country can absorb only a definite quantity of money.126 “It is the complicated operations of demand and competition which determines the standard price of everything”; the latter “does not in the least depend on the quantity of gold and silver in the country.”127 What then will become of the gold and silver that is not required as coin? They are hoarded or used in the manufacture of articles of luxury. If the quantity of gold and silver fall below the level required for circulation, symbolic money or other substitutes take its place. If a favorable rate of exchange brings about a surplus of money in the country and cuts off at the same time the demand for its shipment abroad, it will accumulate in strong-boxes, where the “riches will remain without producing more effect than if they had remained in the
The second law discovered by Steuart is that of the reflux of credit circulation to its starting point. Finally, he works out the effects which the disparity of the rates of interest in different countries produces upon the international export and import of precious metals. The last two points we mention here only for the sake of completeness, since they have but a remote bearing on the subject of our discussion.128 Symbolic money or credit money—Steuart does not as yet distinguish between the two forms of money—may take the place of precious metals as a means of purchase or means of payment in the sphere of home circulation, but never in the world market. Paper notes are therefore “money of
