The Theory of Money and Credit - Ludwig von Mises [22]
The controversy about the concept of money is not exactly one of the most satisfactory chapters in the history of our science. It is chiefly remarkable for the smother of juristic and commercial technicalities in which it is enveloped and for the quite undeserved significance that has been attached to what is after all merely a question of terminology. The solution of the question has been regarded as an end in itself and it seems to have been completely forgotten that the real aim should have been simply to facilitate further investigation. Such a discussion could not fail to be fruitless.
In attempting to draw a line of division between money and those objects that outwardly resemble it, we only need to bear in mind the goal of our investigation. The present discussion aims at tracing the laws that determine the exchange ratio between money and other economic goods. This and nothing else is the task of the economic theory of money. Now our terminology must be suited to our problem. If a particular group of objects is to be singled out from among all those that fulfill a monetary function in commerce and, under the special name of money (which is to be reserved to this group alone), sharply contrasted with the rest (to which this name is denied), then this distinction must be made in a way that will facilitate the further progress of the investigation.
It is considerations such as these that have led the present writer to give the name of money substitutes and not that of money to those objects that are employed like money in commerce but consist in perfectly secure and immediately convertible claims to money.
Claims are not goods;[1] they are means of obtaining disposal over goods. This determines their whole nature and economic significance. They themselves are not valued directly, but indirectly; their value is derived from that of the economic goods to which they refer. Two elements are involved in the valuation of a claim: first, the value of the goods to whose possession it gives a right; and, second, the greater or less probability that possession of the goods in question will actually be obtained. Furthermore, if the claim is to come into force only after a period of time, then consideration of this circumstance will constitute a third factor in its valuation. The value on January 1 of a right to receive ten sacks of coal on December 31 of the same year will be based not directly on the value of ten sacks of coal, but on the value of ten sacks of coal to be delivered in a year's time. This sort of calculation is a matter of common experience, as also is the fact that in reckoning the value of claims their soundness or security is taken into account.
Claims to money are, of course, no exception. Those which are payable on demand, if there is no doubt about their soundness and no expense connected with their settlement, are valued just as highly as cash and tendered and accepted in the same way as money. [2] Only claims of this sort—that is, claims that are payable on demand, absolutely safe as far as human foresight goes, and perfectly liquid in the legal sense—are for business purposes exact substitutes for the money to which they refer. Other claims, of course, such as notes issued by banks of doubtful credit or bills that are not yet mature, also enter into financial transactions and may just as well be employed as general media of exchange. This, according to our terminology, means that they are money. But then they are valued independently; they are reckoned equivalent neither to the sums of money to which they refer nor even to the worth of the rights that they embody. What the further special factors are that help to determine their exchange value, we shall discover in the course of our argument.
