The Theory of Money and Credit - Ludwig von Mises [42]
We have shown that, under certain conditions, indirect exchange is a necessary phenomenon of the market. The circumstance that goods are desired and acquired in exchange not for their own sakes but only in order to be disposed of in further exchange can never disappear from our type of market dealing, because the conditions that make it inevitable are present in the overwhelming majority of all exchange transactions. Now the economic development of indirect exchange leads to the employment of a common medium of exchange, to the establishment and elaboration of the institution of money. Money, in fact, is indispensable in our economic order But as an economic good it is not a physical component of the social distributive apparatus in the way that account books, prisons, or firearms are. No part of the total result of production is dependent on the collaboration of money, even though the use of money may be one of the fundamental principles on which the economic order is based.
Production goods derive their value from that of their products. Not so money; for no increase in the welfare of the members of a society can result from the availability of an additional quantity of money. The laws which govern the value of money are different from those which govern the value of production goods and from those which govern the value of consumption goods. All that these have in common is their general underlying principle, the fundamental economic law of value. This is a complete justification of the suggestion put forward by Knies that economic goods should be divided into means of production, objects of consumption, and media of exchange; for, after all, the primary object of economic terminology is to facilitate investigation into the theory of value.
2 Money as Part of Private Capital
We have not undertaken this investigation into the relationship between money and production goods merely for its terminological interest. What is of importance for its own sake is not our ultimate conclusion, but the incidental light shed by our argument upon those peculiarities of money that distinguish it from other economic goods. These special characteristics of the common medium of exchange will receive closer attention when we turn to consider the laws that regulate the value of money and its variations.
But the result of our reasoning, too, the conclusion that money is not a production good, is not entirely without significance. It will help us to answer the question whether money is capital or not. This question in its turn is not an end in itself, but it provides a check upon the answer to a further problem concerning the relations between the equilibrium rate of interest and the money rate of interest, which will be dealt with in the third part of this book. If each conclusion confirms the other, then we may assume with a considerable degree of assurance that our arguments have not led us into error.
The first grave difficulty in the way of any investigation into the relation between money and capital arises from the difference of opinion that exists about the definition of the concept of capital. The views of scholars on the definition of capital are more divergent than their views on any other point of economics. None of the many definitions that have been suggested has secured general recognition; nowadays, in fact, the controversy about the theory of capital rages more fiercely than ever. If from among the large number of conflicting concepts we select that of Böhm-Bawerk to guide us in our investigation into the relation of money to capital, we could justify our procedure merely by reference to the fact that Böhm-Bawerk is the best guide for any serious attempt to study the problem of interest, even if such a study leads eventually (and
