Ludwig von Mises, The Theory of Money and Credit

"The function of money is to facilitate the business of the market by acting as a common medium of exchange."

"To a naive observer, money made out of precious metal was 'sound money' because the piece of precious metal was an 'intrinsically' valuable object, while paper money was 'bad money' because its value was only 'artificial'. But even the layman who holds this opinion accepts the money in the course of business transactions, not for the sake of its industrial use-value, but for the sake of its objective exchange-value, which depends largely upon its monetary employment. He values a gold coin not merely for the sake of its industrial use-value, say because of the possibility of using it as jewellery, but chiefly on account of its monetary utility. But, of course, to do something, and to render an account to oneself of what one does and why one does it, are quite different things."

"In the case of money, subjective use-value and subjective exchange-value coincide. Both are derived from objective exchange-value, for money has no utility other than that arising from the possibility of obtaining other economic goods in exchange for it."

"The exchange-value of money is the anticipated use-value of the things that can be obtained with it."

"For when the Law of Price declares that a good actually commands a particular price, and explains why it does so, it of course implies that the good is able to command this price, and explains why it is able to do so. The Law of Price comprehends the Law of Exchange-Value."

"It is impossible to say how far the present value of money depends on its monetary employment and how far on its industrial employment. When the institution of money was first established, the industrial basis of the value of the precious metals may have preponderated; but with progress in the monetary organization of economic life the monetary employment has become more and more important. It is certain that nowadays the value of gold is largely supported by its monetary employment, and that its demonetization would affect its price in an overwhelming fashion."

"Under bilateral competition, market-price is determined within a range whose upper limit is set by the valuations of the lowest bidder among the actual buyers and the highest offerer among the excluded would-be sellers, and whose lower limit is set by the valuations of the lowest offerer among the actual sellers and the highest bidder among the excluded would-be buyers."

"The first value of money was clearly the value which the goods used as money possessed (thanks to their suitability for satisfying human wants in other ways) at the moment when they were first used as common media of exchange."

"If the objective exchange-value of money must always be linked with a pre-existing market exchange-ratio between money and other economic goods (since otherwise individuals would not be in a position to estimate the value of the money), it follows that an object cannot be used as money unless, at the moment when its use as money begins, it already possesses an objective exchange-value based on some other use."

"Alterations in real prices occur slowly as a rule. But this stability of prices has its cause in the stability of the price-determinants, not in the Law of Price-determination itself. Prices change slowly because the subjective valuations of human beings change slowly. Human needs, and human opinions as to the suitability of goods for satisfying those needs, are no more liable to frequent and sudden changes than are the stocks of goods available for consumption, or the manner of their social distribution;"

"If all the exchange-ratios of the past were erased from human memory, the process of market-price-determination might certainly become more difficult, because everybody would have to construct a new scale of valuations for himself; but it would not become impossible. In fact, people the whole world over are engaged daily and hourly in the operation from which all prices result: the decision as to the relative significance enjoyed by specific quantities of goods as conditions for the satisfaction of wants."

"The marginal utility of money to any individual, i.e., the marginal utility derivable from the goods that can be obtained with the given quantity of money or that must be surrendered for the required money, presupposes a certain exchange-value of the money; so the latter cannot be derived from the former. 1 Those who have realized the significance of historically-transmitted values in the determination of the objective exchange-value of money will not find great difficulty in escaping from this apparently circular argument."

"The objective exchange-value of money which rules in the market to-day is derived from yesterday's under the influence of the subjective valuations of the individuals frequenting the market, just as yesterday's in its turn was derived under the influence of subjective valuations from the objective exchange-value possessed by the money the day before yesterday. If in this way we continually go farther and farther back we must eventually arrive at a point where we no longer find any component in the object Ive exchange-value of money that arises from valuations based on the function of money as a common medium of exchange; where the value of money is nothing other than the value of an object that is useful in some other way than as money."

"Before it was usual to acquire goods in the market, not for personal consumption, but simply in order to exchange them again for the goods that were really wanted, each individual commodity was only accredited with that value given by the subjective valuations based on its direct utility. It was not until it became customary to acquire certain goods merely in order to use them as media of exchange that people began to esteem them more highly than before, on account of this possibility of using them in indirect exchange. The individual valued them in the first place because they were useful in the ordinary sense, and then additionally because they could be used as media of exchange. Both sorts of valuation are subject to the law of marginal utility."

"The role played by man in production always consists solely in combining his personal forces with the forces of Nature in such a way that the cooperation leads to some particular desired arrangement of material. No human act of production amounts to more than altering the position of things in space and leaving the rest to Nature."

"The mistake in the argument of those who suppose that a variation in the quantity of money results in an inversely proportionate variation in its purchasing power lies in its starting-point. If we wish to arrive at a correct conclusion, we must start with the valuations of separate individuals; we must examine the way in which an increase or decrease in the quantity of money affects the value-scales of individuals, for it is from these alone that variations in the exchange-ratios of goods proceed."

"Let us assume that a man gets half his income in the form of interest-bearing securities and half in the form of money; and that he is in the habit of saving three-quarters of his income, and does this by retaining the securities and using that half of his income which he receives in cash in equal parts for paying for current consumption and for the purchase of further securities. Now let us assume that a variation in the composition of his income occurs, so that he receives three-quarters of it in cash and only one-quarter in securities. From now on this man will use two-thirds of his cash receipts for the purchase of interest-bearing securities. If the price of the securities rises or, which is the same thing, if their rate of interest falls, then in either case he will be less willing to buy and will reduce the sum of money that he would otherwise have employed for their purchase; he is likely to find that the advantage of a slightly increased reserve exceeds that which could be obtained from the acquisition of the securities. In the second case he will doubtless be inclined to pay a higher price, or more correctly, to purchase a greater quantity at the higher price, than in the first case. But he will certainly not be prepared to pay double as much for a unit of securities in the second case as in the first case."

"If we compare two static economic systems, which differ in no way from one another except that in one there is twice as much money as in the other, it appears that the purchasing power of the monetary unit in the one system must be equal to half that of the monetary unit in the other. Nevertheless, we may not conclude from this that a doubling of the quantity of money must lead to a halving of the purchasing power of the monetary unit; for every variation in the quantity of money introduces a dynamic factor into the static economic system. The new position of static equilibrium that is established when the effects of the fluctuations thus set in motion are completed cannot be the same as that which existed before the introduction of the additional quantity of money. Consequently, in the new state of equilibrium the conditions of demand for money, given a certain exchange-value of the monetary unit, will also be different. If the purchasing power of each unit of the doubled quantity of money were halved, the unit would not have the same significance for each individual under the new conditions as it had in the static system before the increase in the quantity of money."

"The core of the doctrine consists in the proposition that the supply of money and the demand for it both affect its value. This proposition is probably a sufficiently good hypothesis to explain big changes in prices; but it is far from containing a complete theory of the value of money. It describes one cause of changes in prices; it is nevertheless inadequate for dealing with the problem exhaustively. By itself it does not comprise a theory of the value of money; it needs the basis of a general value theory. One after another, the doctrine of supply and demand, the cost-of-production theory, and the subjective theory of value have had to provide the foundations for the Quantity Theory."

"Fiscal considerations have led to the promulgation of a theory that attributes to the minting authority the right to regulate the purchasing power of the coinage as it thinks fit. For just as long as the minting of coins has been a government function, governments have tried to fix the weight and content of the coins as they wished. Philip VI of France expressly claimed the right "to mint such money and give it such currency and at such rate as we desire and seems good to us" and all medieval rulers thought and did as he in this matter. Obliging jurists supported them by attempts to discover a philosophical basis for the divine right of kings to debase the coinage and to prove that the true value of the coins was that assigned to them by the ruler of the country."
