which their actual level could not be explained. This component, too, is derived from exchange ratios which can be entirely explained by reference to the subjective valuations of the individuals taking part in the market, even though these valuations were not originally grounded upon the specifically monetary utility alone of these goods. The valuation of money by the market can only start from a value possessed by the money in the past, and this relationship influences the new level of the objective exchange value of money. The historically transmitted value is transformed by the market without regard to what has become its historical content. [9] But it is not merely the starting point for today's objective exchange value of money; it is an indispensable element in its determination. The individual must take into account the objective exchange value of money, as determined in the market yesterday, before he can form an estimate of the quantity of money that he needs today. The demand for money and the supply of it are thus influenced by the value of money in the past; but they in their turn modify this value until they are brought into equilibrium.

4 The Applicability of the Marginal-Utility Theory to Money

Demonstration of the fact that search for the determinants of the objective exchange value of money always leads us back to a point where the value of money is not determined in any way by its use as a medium of exchange, but solely by its other functions, prepares the way for developing a complete theory of the value of money on the basis of the subjective theory of value and its peculiar doctrine of marginal utility.

Until now the subjective school has not succeeded in doing this. In fact, among the few of its members who have paid any attention at all to the problem there have been some who have actually attempted to demonstrate its insolubility. The subjective theory of value has been helpless in face of the task here confronting it.

There are two theories of money which, whatever else we may think of them, must be acknowledged as having attempted to deal with the whole problem of the value of money.

The objective theories of value succeeded in introducing a formally unexceptionable theory of money into their systems, which deduces the value of money from its cost of production. [10] It is true that the abandonment of this monetary theory is not merely to be ascribed to those shortcomings of the objective theory of value in general which led to its supersession by the theory of the modern school. Apart from this fundamental weakness, the cost-of-production theory of the value of money exhibited one feature that was an easy target for criticism. While it certainly provided a theory of commodity money (even if only a formally correct one), it was unable to deal with the problem of credit money and fiat money. Nevertheless, it was a complete theory of money insofar as it did at least attempt to give a full explanation of the value of commodity money.

The other similarly complete theory of the value of money is that version of the quantity theory associated with the name of Davanzati. [11] According to this theory, all the things that are able to satisfy human wants are conventionally equated with all the monetary metal. From this, since what is true of the whole is also true of its parts, the exchange ratios between commodity units and units of money can be deduced. Here we are confronted with a hypothesis that is not in any way supported by facts. To demonstrate its untenability once more would nowadays be a waste of time. Nevertheless, it must not be overlooked that Davanzati was the first who attempted to present the problem as a whole and to provide a theory that would explain not merely the variations in an existing exchange ratio between money and other economic goods, but also the origin of this ratio.

The same cannot be said of other versions of the quantity theory. These all tacitly assume a certain value of money as given, and absolutely refuse to investigate further into the matter. They overlook
