PART TWO

THE VALUE OF MONEY

CHAPTER 7

The Concept of the Value of Money

1 Subjective and Objective Factors in the Theory of the Value of Money

The central element in the economic problem of money is the objective exchange value of money, popularly called its purchasing power. This is the necessary starting point of all discussion; for it is only in connection with its objective exchange value that those peculiar properties of money that have differentiated it from commodities are conspicuous.

This must not be understood to imply that subjective value is of less importance in the theory of money than elsewhere. The subjective estimates of individuals are the basis of the economic valuation of money just as of that of other goods. And these subjective estimates are ultimately derived, in the case of money as in the case of other economic goods, from the significance attaching to a good or complex of goods as the recognized necessary condition for the existence of a utility, given certain ultimate aims on the part of some individual.^*1 Nevertheless, while the utility of other goods depends on certain external facts (the objective use-value of the commodity) and certain internal facts (the hierarchy of human needs), that is, on conditions that do not belong to the category of the economic at all but are partly of a technological and partly of a psychological nature, the subjective value of money is conditioned by its objective exchange value, that is, by a characteristic that falls within the scope of economics.

In the case of money, subjective use-value and subjective exchange value coincide.^*2 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. It is impossible to conceive of any function of money, qua money, that can be separated from the fact of its objective exchange value. As far as the use-value of a commodity is concerned, it is immaterial whether the commodity also has exchange value or not; but for money to have use-value, the existence of exchange value is essential.

This peculiarity of the value of money can also be expressed by saying that, as far as the individual is concerned, money has no use-value at all, but only subjective exchange value. This, for example, is the practice of Rau^*3 and Böhm-Bawerk.^*4 Whether the one or the other phraseology is employed, scientific investigation of the characteristic will lead to the same conclusions. There is no reason to enter upon a discussion of this point, especially since the distinction between value in use and value in exchange no longer holds the important place in the theory of value that it used to have.^*5 All that we are concerned with is to show that the task of economics in dealing with the value of money is a bigger one than its task in dealing with the value of commodities. When explaining the value of commodities, the economist can and must be content to take subjective use-value for granted and leave investigation of its origins to the psychologist; but the real problem of the value of money only begins where it leaves off in the case of commodity values, viz., at the point of tracing the objective determinants of its subjective value, for there is no subjective value of money without objective exchange value. It is not the task of the economist, but of the natural scientist, to explain why corn is useful to man and valued by him; but it is the task of the economist alone to explain the utility of money. Consideration of the subjective value of money without discussion of its objective exchange value is impossible. In contrast to commodities, money would never be used unless it had an objective exchange value or purchasing power. The subjective value of money always depends on the subjective value of the other economic goods that can be obtained in exchange for it. Its subjective value is in fact a derived concept. If we wish to estimate the significance that a given sum of money has, in view of the known dependence upon it of a certain satisfaction, we can do this only on the assumption that the money possesses a given objective exchange value. "The exchange value of money is the anticipated use-value of the things that can be obtained with it."^*6 Whenever money is valued by anybody it is because he supposes it to have a certain purchasing power.

It might possibly be objected that the mere possession by money of an undefined amount of objective exchange value is not alone sufficient to guarantee the possibility of using it as a medium of exchange; that it is also necessary that this purchasing power should be present in a certain degree, neither too great nor too small, but such that the proportion between the value of the units of money and that of the units of commodity is a convenient one for carrying through the ordinary exchange transactions of daily life; that even if it were true that half of the money in a country could perform the same service as the whole stock if the value of the monetary unit were doubled, yet it is doubtful if a similar proposition could be asserted of the case in which its value was increased a millionfold, or diminished to one-millionth, in inverse correspondence with changes in the quantity of it, since such a currency would hardly be capable of fulfilling the functions of a common medium of exchange so well as the currencies in actual use; that we should try to imagine a commodity money of which a whole ton, or one of which only a thousandth of a milligram was equivalent to a dollar, and think of the inconveniences, the insuperable obstacles in fact, which the employment of such a medium would inevitably place in the way of commerce.

However true this may be, the question of the actual dimensions of the exchange ratio between money and commodities and of the size of the monetary unit is not an economic problem. It is a question that belongs to discussion of the technical conditions that make any particular good suitable for use as money. The relative scarcity of the precious metals, great enough to give them a high objective exchange value but not so great as that of the precious stones or radium and therefore not great enough to make their exchange value too high, must indeed be reckoned, along with such of their other characteristics as their practically unlimited divisibility, their malleability, and their powers of resistance to destructive external influences, as among the factors that were once decisive in causing them to be recognized as the most marketable goods and consequently to be employed as money. But nowadays, as monetary systems have developed, the particular level of value of the precious metals no longer has any important bearing on their use as money. The modern organization of the clearing system and the institution of fiduciary media have made commerce independent of the volume and weight of the monetary material.

2 The Objective Exchange Value of Money

It follows from what has been said that there can be no discussion of the problem of the value of money without consideration of its objective exchange value. Under modern conditions, objective exchange value, which Wieser also calls Verkehrswert (or value in business transactions), is the most important kind of value, because it governs the social and not merely the individual aspect of economic life. Except in its explanation of the fundamentals of value theory, economics deals almost exclusively with objective exchange value.^*7 And while this is true to some extent of all goods, including those which are useful apart from any exchange value which they possess, it is still truer of money.

"The objective exchange value of goods is their objective significance in exchange, or, in other words, their capacity in given circumstances to procure a specific quantity of other goods as an equivalent in exchange."^*8 It should be observed that even objective exchange value is not really a property of the goods themselves, bestowed on them by nature, for in the last resort it also is derived from the human process of valuing individual goods. But the exchange ratios that are established between different goods in commercial transactions, and are determined by the collective influence of the subjective valuations of all the persons doing business in the market, present themselves to separate individuals, who usually have an infinitesimal influence on the determination of the ratios, as accomplished facts, which in most cases have to be accepted unconditionally. It has thus been easy for false abstraction from this state of affairs to give rise to the opinion that each good comes to the market endowed with a definite quantity of value independent of the valuations of individuals.^*9 From this point of view, goods are not exchanged for one another, by human beings; they simply exchange.

Objective exchange value, as it appears in the subjective theory of value, has nothing except its name in common with the old idea developed by the Classical School of a value in exchange inherent in things themselves. In the value theory of Smith and Ricardo, and in that of their successors, value in exchange plays the leading part. These theories attempt to explain all the phenomena of value by starting from value in exchange, which they interpret as labor value or cost-of-production value. For modern value theory their terminology can claim only a historical importance, and a confusion of the two concepts of exchange value need no longer be feared. This removes the objections that have recently been made to the continued use of the expression "objective exchange value."^*10

If the objective exchange value of a good is its power to command a certain quantity of other goods in exchange, its price is this actual quantity of other goods. It follows that the concepts of price and objective exchange value are by no means identical. "But it is, nevertheless, true that both obey the same laws. 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."^*11

By "the objective exchange value of money" we are accordingly to understand the possibility of obtaining a certain quantity of other economic goods in exchange for a given quantity of money; and by "the price of money" this actual quantity of other goods. It is possible to express the exchange value of a unit of money in units of any other commodity and speak of the commodity price of money; but in actual life this phraseology and the concept it expresses are unknown. For nowadays money is the sole indicator of prices.

3 The Problems Involved in the Theory of the Value of Money

The theory of money must take account of the fundamental difference between the principles which govern the value of money and those which govern the value of commodities. In the theory of the value of commodities it is not necessary at first to pay any attention to objective exchange value. In this theory, all phenomena of value and price determination can be explained with subjective use-value as the starting point. It is otherwise in the theory of the value of money; for since money, in contrast to other goods, can fulfill its economic function only if it possesses objective exchange value, an investigation into its subjective value demands an investigation first into this objective exchange value. In other words, the theory of the value of money leads us back through subjective exchange value to objective exchange value.

Under the present economic system, which is founded on the division of labor and the free exchange of products, producers as a rule do not work directly on their own behalf but with a view to supplying the market. Consequently their economic calculations are determined not by the subjective use-values of their products, but by their subjective exchange values. Valuations which ignore the subjective exchange value, and consequently the objective exchange value, of a product and take account only of its subjective use-value, are nowadays most exceptional. They are on the whole limited to those cases in which the object has a sentimental value. But if we disregard those things to which certain individuals attach a symbolical significance because they remind them of experiences or persons that they wish to remember, while in the eyes of others for which they have not this personal interest the things possess a very much lower value or even no value at all, it cannot be denied that human valuations of goods are based upon their exchange value. It is not use-value, but exchange value, that appears to govern the modern economic order. Nevertheless, if we trace to its deepest springs, first the subjective and then the objective exchange value of commodities, we find that in the last resort it is still the subjective use-value of things that determines the esteem in which they are held. For, quite apart from the fact that the commodities acquired in exchange for the products are always valued according to their subjective use-value, the only valuations that are of final importance in the determination of prices and objective exchange value are those based on the subjective use-value that the products have for those persons who are the last to acquire them through the channels of commerce and who acquire them for their own consumption.

The case of money is different. Its objective exchange value cannot be referred back to any sort of use-value independent of the existence of this objective exchange value. In the origins of monetary systems, money is still a commodity which eventually ceases to circulate on reaching the hands of a final buyer or consumer.^*12 In the early stages of the history of money there were even monetary commodities whose natural qualities definitely precluded their employment as money for more than a short time. An ox or a sack of corn cannot remain in circulation for ever; it has sooner or later to be withdrawn for consumption if that part of its value which does not depend on its employment as money is not to be diminished by a deterioration of its substance. In a developed monetary system, on the other hand, we find commodity money, of which large quantifies remain constantly in circulation and are never consumed or used in industry; credit money, whose foundation, the claim to payment, is never made use of; and possibly even fiat money, which has no use at all except as money.

Many of the most eminent economists have taken it for granted that the value of money and of the material of which it is made depends solely on its industrial employment and that the purchasing power of our present-day metallic money, for instance, and consequently the possibility of its continued employment as money, would immediately disappear if the properties of the monetary material as a useful metal were done away with by some accident or other.^*13 Nowadays this opinion is no longer tenable, not merely because there is a whole series of phenomena which it leaves unaccounted for, but chiefly because it is in any case opposed to the fundamental laws of the theory of economic value. To assert that the value of money is based on the nonmonetary employment of its material is to eliminate the real problem altogether.^*14 Not only have we to explain the possibility of fiat money, the material of which has a far lower value without the official stamp than with it; we must also answer the question, whether the possibility of a monetary employment of the commodity money material affects its utility and consequently its value, and if so to what extent. The same problem arises in the case of credit money.

Part of the stock of gold at the command of mankind is used for monetary purposes, part for industrial. A change from one kind of use to the other is always possible. Ingots pass from the vaults of the banks to the workshops of the goldsmiths and gilders, who also directly withdraw current coins from circulation and melt them down. On the other hand, things made of gold, even with a high value as works of art, find their way to the mint when unfavorable market conditions render a sale at anything higher than the bullion price impossible. One and the same piece of metal can even fulfill both purposes simultaneously, as will be seen if we think of ornaments that are used as money or of a coin that is worn by its owner as jewelry until he parts with it again.^*15

Investigations into the foundations of the value of money must eliminate those determinants that arise from the properties of the monetary material as a commodity, since these present no peculiarity that could distinguish the value of money from that of other commodities. The value of commodity money is of importance for monetary theory only insofar as it depends on the peculiar economic position of the money, on its function as a common medium of exchange. Changes in the value of the monetary material that arise from its characteristics as a commodity are consequently to be considered only so far as they seem likely to make it more or less suitable for performing the function of money. Apart from this, monetary theory must take the value of the monetary material that arises from its industrial usefulness as given.

The material of which commodity money is made must have the same value whether it is used as money or otherwise. Whether a change in the value of gold originates in its employment as money or in its employment as a commodity, in either case the value of the whole stock changes uniformly.^*16

It is otherwise with credit money and fiat money. With these, the substance that bears the impression is essentially insignificant in the determination of the value of the money. In some circumstances it may have a relatively high exchange value comprising a considerable fraction of the total exchange value of the individual coin or note. But this value, which is not based on the monetary properties of the coin or note, only becomes of practical importance at the moment when the value based on the monetary property vanishes, that is, at the moment when the individuals participating in commerce cease to use the coin or note in question as a common medium of exchange. When this is not the case, the coins or notes bearing the monetary impression must have a higher exchange value than other pieces of the same material so long as these are not marked out by any special characteristics.

Again, in the case of credit money the claims used as money have similarly a different exchange value from other claims of the same kind that are not used as money. The hundred-gulden notes which circulated as money in Austria-Hungary before the reform of the currency had a higher exchange value than, say, a government security with a nominal value of a hundred gulden, notwithstanding the fact that the latter bore interest and the former did not.

Until gold was used as money it was valued merely on account of the possibility of using it for ornamental purposes. If it had never been used as money, or if it had ceased to be so used, its present-day value would be determined solely by the extent to which it was known to be useful in industry. But additional opportunities of using it provided an addition to the original reasons for esteeming it; gold began to be valued partly because it could be used as a common medium of exchange. It is not surprising that its value consequently rose, or that at least a decrease in its value which possibly would have occurred for other reasons was counterbalanced. Nowadays the value of gold, our principal modern monetary material, is based on both possibilities of employment, on that for monetary purposes and on that for industrial purposes.^*17

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.^*18 The sharp decline in the price of silver since 1873 is recognized as largely due to the demonetization of this metal in most countries. And when, between 1914 and 1918, many countries replaced gold by banknotes and Treasury notes so that gold flowed to those countries that had remained on a gold standard, the value of gold fell very considerably.

The value of the materials that are used for the manufacture of fat money and credit money is also influenced by their use as money as well as by all their other uses. The production of token coins is nowadays one of the most important uses of silver, for example. Again, when the minting of coins from nickel was begun over fifty years ago, the price of nickel rose so sharply that the director of the English mint stated in 1873 that if minting from nickel were continued the cost of the metal alone would exceed the face value of the coins.^*19 If we prefer to regard this sort of use as industrial and not monetary, however, it is because token coins are not money but money substitutes, and consequently the peculiar interactions between changes in the value of money and changes in the value of the monetary material are absent in these cases.

The task of the theory of the value of money is to expound the laws which regulate the determination of the objective exchange value of money. It is not its business to concern itself with the determination of the value of the material from which commodity money is made so far as this value does not depend on the monetary, but on the other, employment of this material. Neither is it its task to concern itself with the determination of the value of those materials that are used for making the concrete embodiments of fiat money. It discusses the objective exchange value of money only insofar as this depends on its monetary function.

The other forms of value present no special problems for the theory of the value of money. There is nothing to be said about the subjective value of money that differs in any way from what economics teaches of the subjective value of other economic goods. And all that it is important to know about the objective use-value of money may be summed up in the one statement—it depends on the objective exchange value of money.

CHAPTER 8

The Determinants of the Objective Exchange Value, or Purchasing Power, of Money

(I) The Element of Continuity in the
Objective Exchange Value of Money

1 The Dependence of the Subjective Valuation of Money on the Existence of Objective Exchange Value

According to modern value theory, price is the resultant of the interaction in the market of subjective valuations of commodities and price goods. From beginning to end, it is the product of subjective valuations. Goods are valued by the individuals exchanging them, according to their subjective use-values, and their exchange ratios are determined within that range where both supply and demand are in exact quantitative equilibrium. The law of price stated by Menger and Böhm-Bawerk provides a complete and numerically precise explanation of these exchange ratios; it accounts exhaustively for all the phenomena of direct exchange. 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.

This law of price is just as valid for indirect as for direct exchange. The price of money, like other prices, is determined in the last resort by the subjective valuations of buyers and sellers. But, as has been said already, the subjective use-value of money, which coincides with its subjective exchange value, is nothing but the anticipated use-value of the things that are to be bought with it. The subjective value of money must be measured by the marginal utility of the goods for which the money can be exchanged.^*20

It follows that a valuation of money is possible only on the assumption that the money has a certain objective exchange value. Such a point d'appui is necessary before the gap between satisfaction and "useless" money can be bridged. Since there is no direct connection between money as such and any human want, individuals can obtain an idea of its utility and consequently of its value only by assuming a definite purchasing power. But it is easy to see that this supposition cannot be anything but an expression of the exchange ratio ruling at the time in the market between the money and commodities.^*21

Once an exchange ratio between money and commodities has been established in the market, it continues to exercise an influence beyond the period during which it is maintained; it provides the basis for the further valuation of money. Thus the past objective exchange value of money has a certain significance for its present and future valuation. The money prices of today are linked with those of yesterday and before, and with those of tomorrow and after.

But this alone will not suffice to explain the problem of the element of continuity in the value of money; it only postpones the explanation. To trace back the value that money has today to that which it had yesterday, the value that it had yesterday to that which it had the day before, and so on, is to raise the question of what determined the value of money in the first place. Consideration of the origin of the use of money and of the particular components of its value that depend on its monetary function suggests an obvious answer to this question. 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. When individuals began to acquire objects, not for consumption, but to be used as media of exchange, they valued them according to the objective exchange value with which the market already credited them by reason of their "industrial" usefulness, and only as an additional consideration on account of the possibility of using them as media of exchange. The earliest value of money links up with the commodity value of the monetary material. But the value of money since then has been influenced not merely by the factors dependent on its "industrial" uses, which determine the value of the material of which the commodity money is made, but also by those which result from its use as money. Not only its supply and demand for industrial purposes, but also its supply and demand for use as a medium of exchange, have influenced the value of gold from that point of time onward when it was first used as money.^*22

2 The Necessity for a Value Independent of the Monetary Function Before an Object Can Serve as Money

If the objective exchange value of money must always be linked with a preexisting 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. This provides both a refutation of those theories which derive the origin of money from a general agreement to impute fictitious value to things intrinsically valueless^*23 and a confirmation of Menger's hypothesis concerning the origin of the use of money.

This link with a preexisting exchange value is necessary not only for commodity money, but equally for credit money and fiat money.^*24 No fiat money could ever come into existence if it did not satisfy this condition. Let us suppose that, among those ancient and modern kinds of money about which it may be doubtful whether they should be reckoned as credit money or fiat money, there have actually been representatives of pure fiat money. Such money must have come into existence in one of two ways. It may have come into existence because money substitutes already in circulation, that is, claims payable in money on demand, were deprived of their character as claims, and yet still used in commerce as media of exchange. In this case, the starting point for their valuation lay in the objective exchange value that they had at the moment when they were deprived of their character as claims. The other possible case is that in which coins that once circulated as commodity money are transformed into fiat money by cessation of free coinage (either because there was no further minting at all or because minting was continued only on behalf of the Treasury), no obligation of conversion being de jure or de facto assumed by anybody, and nobody having any grounds for hoping that such an obligation ever would be assumed by anybody. Here the starting point for the valuation lies in the objective exchange value of the coins at the time of the cessation of free coinage.

Before an economic good begins to function as money it must already possess exchange value based on some other cause than its monetary function. But money that already functions as such may remain valuable even when the original source of its exchange value has ceased to exist. Its value then is based entirely on its function as common medium of exchange.^*25

3 The Significance of Preexisting Prices in the Determination of Market Exchange Ratios

From what has just been said, the important conclusion follows that a historically continuous component is contained in the objective exchange value of money.

The past value of money is taken over by the present and transformed by it; the present value of money passes on into the future and is transformed in its turn. In this there is a contrast between the determination of the exchange value of money and that of the exchange value of other economic goods. All preexisting exchange ratios are quite irrelevant so far as the actual levels of the reciprocal exchange ratios of other economic goods are concerned. It is true that if we look beneath the concealing monetary veil to the real exchange ratios between goods we observe a certain continuity. 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. The fact that today's market price is seldom very different from yesterday's is to be explained by the fact that the circumstances that determined yesterday's price have not greatly changed overnight, so that today's price is a resultant of nearly identical factors. If rapid and erratic variations in prices were usually encountered in the market, the conception of objective exchange value would not have attained the significance that it is actually accorded both by consumer and producer.

In this sense, reference to an inertia of prices is unobjectionable, although the errors of earlier economists should warn us of the real danger that the use of terms borrowed from mechanics may lead to a "mechanical" system, that is, to one that abstracts erroneously from the subjective valuations of individuals. But any suggestion of a causal relationship between past and present prices must be decisively rejected.

It is not disputed that there are institutional forces in operation which oppose changes in prices that would be necessitated by changes in valuations, and which are responsible when changes in prices that would have been caused by changes in supply and demand are postponed and when small or transitory changes in the relations between supply and demand lead to no corresponding change in prices at all. It is quite permissible to speak of an inertia of prices in this sense. Even the statement that the closing price forms the starting point for the transactions of the next market^*26 may be accepted if it is understood in the sense suggested above. If the general conditions that determined yesterday's price have altered but little during the night, today's price should be but little different from that of yesterday, and in practice it does not seem incorrect to make yesterday's the starting point. Nevertheless, there is no causal connection between past and present prices as far as the relative exchange ratios of economic goods (not including money) are concerned. The fact that the price of beer was high yesterday cannot be of the smallest significance as far as today's price is concerned—we need only think of the effect upon the prices of alcoholic drinks that would follow a general triumph of the Prohibition movement. Anybody who devotes attention to market activities is daily aware of alterations in the exchange ratios of goods, and it is quite impossible for anybody who is well acquainted with economic phenomena to accept a theory which seeks to explain price changes by a supposed constancy of prices.

It may incidentally be remarked that to trace the determination of prices back to their supposed inertia, as even Zwiedineck in his pleadings for this assumption is obliged to admit, is to resign at the outset any hope of explaining the ultimate causes of prices and to be content with explanations from secondary causes.^*27 It must unreservedly be admitted that an explanation of the earliest forms of exchange transaction that can be shown to have existed—a task to the solution of which the economic historian has so far contributed but little would show that the forces that counteract sudden changes in prices were once stronger than they are now. But it must positively be denied that there is any sort of connection between those early prices and those of the present day; that is, if there really is anybody who believes it possible to maintain the assertion that the exchange ratios of economic goods (not the money prices) that prevail today on the German stock exchanges are in any sort of causal connection with those that were valid in the days of Hermann or Barbarossa. 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.

It is so far as the money prices of goods are determined by monetary factors, that a historically continuous component is included in them, without 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.^*28 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.^*29 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.^*30 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 the fact that what is required is an explanation of what determines the exchange ratio between money and commodities, and not merely of what causes changes in this ratio. In this respect, the quantity theory resembles various general theories of value (many versions of the doctrine of supply and demand, for example), which have not attempted to explain price as such but have been content to establish a law of price variations.^*31 These forms of the quantity theory are in fact nothing but the application of the law of supply and demand to the problem of the value of money. They introduce into monetary theory all the strong points of this doctrine; and of course all its weak points as well.^*32

The revolution in economics since 1870 has not yet been any more successful in leading to an entirely satisfactory solution of this problem. Of course, this does not mean that the progress of the science has left no trace on monetary theory in general and on the theory of the value of money in particular. It is one of the many services of the subjective theory of value to have prepared the way for a deeper understanding of the nature and value of money. The investigations of Menger have placed the theory on a new basis. But till now one thing has been neglected. Neither Menger nor any of the many investigators who have tried to follow him have even so much as attempted to solve the fundamental problem of the value of money. Broadly speaking, they have occupied themselves with checking and developing the traditional views and here and there expounding them more correctly and precisely, but they have not provided an answer to the question: What are the determinants of the objective exchange value of money? Menger and Jevons have not touched upon the problem at all. Carver^*33 and Kinley^*34 have contributed nothing of real importance to its solution. Walras^*35 and Kemmerer^*36 assume a given value of money and develop what is merely a theory of variations in the value of money. Kemmerer, it is true, approaches very close to a solution of the problem but passes it by.

Wieser expressly refers to the incomplete nature of the previous treatment. In his criticism of the quantity theory he argues that the law of supply and demand in its older form, the application of which to the problem of money constitutes the quantity theory, has a very inadequate content, since it gives no explanation at all of the way in which value is really determined or of its level at any given time, but confines itself without any further explanation merely to stating the direction in which value will move in consequence of variations in supply or demand; that is, in an opposite direction to changes in the former and in the same direction as changes in the latter. He further argues that it is no longer possible to rest content with a theory of the economic value of money which deals so inadequately with the problem; that since the supersession of the old law of supply and demand as applied to commodities, the case for which it was originally constructed, a more searching law must also be sought to apply to the case of money.^*37 But Wieser does not deal with the problem whose solution he himself states to be the object of his investigation, for in the further course of his argument he declares that the concepts of supply of money and demand for money as a medium of exchange are useless for his purpose and puts forward a theory which attempts to explain variations in the objective exchange value of money (objektive innere Tauschwert des Geldes)^*38 by reference to the relationship that exists in an economic community between money income and real income. For while it is true that reference to the ratio between money income and real income may well serve to explain variations in the objective exchange value of money, Wieser nowhere makes the attempt to evolve a complete theory of money—an attempt which, admittedly, the factors of supply and demand being excluded from consideration, would be certain to fail. The very objection that he raises against the old quantity theory, that it affirms nothing concerning the actual determination of value or the level at which it must be established at any time, must also be raised against his own doctrine; and this is all the more striking inasmuch as it was Wieser who, by revealing the historical element in the purchasing power of money, laid the foundation for the further development of the subjective theory of the value of money.

The unsatisfactory results offered by the subjective theory of value might seem to justify the opinion that this doctrine and especially its proposition concerning the significance of marginal utility must necessarily fall short as a means of dealing with the problem of money. Characteristically enough, it was a representative of the new school, Wicksell, who first expressed this opinion. Wicksell considers that the principle which lies at the basis of all modern investigation into the theory of value, namely, the concept of marginal utility, may well be suited to explaining the determination of exchange ratios between one commodity and another, but that it has practically no significance at all, or at most an entirely secondary significance, in explaining the exchange ratios between money and other economic goods. Wicksell, however, does not appear to detect any sort of objection to the marginal-utility theory in this assertion. According to his argument, the objective exchange value of money is not determined at all by the processes of the market in which money and the other economic goods are exchanged. If the money price of a single commodity or group of commodities is wrongly assessed in the market, then the resulting maladjustments of the supply and demand and the production and consumption of this commodity or group of commodities will sooner or later bring about the necessary correction. If, on the other hand, all commodity prices, or the average price level, should for any reason be raised or lowered, there is no factor in the circumstances of the commodity market that could bring about a reaction. Consequently, if there is to be any reaction at all against a price assessment that is either too high or too low it must in some way or other originate outside the commodity market. In the further course of his argument, Wicksell arrives at the conclusion that the regulator of money prices is to be sought in the relations of the commodity market to the money market, in the broadest sense of the term. The cause which influences the demand for raw materials, labor, the use of land, and other means of production, and thus indirectly determines the upward or downward movement of commodity prices, is the ratio between the money rate of interest (Darlehnszins) and the "natural" or equilibrium rate of interest (natürliche Kapitalzins), by which we are to understand that rate of interest which would be determined by supply and demand if real capital was itself lent directly without the intermediation of money.^*39

Wicksell imagines that this argument of his provides a theory of the determination of the objective exchange value of money. In fact, however, all that he attempts to prove is that forces operate from the loan market on the commodity market which prevent the objective exchange value of money from rising too high or falling too low. He never asserts that the rate of interest on loans determines the actual level of this value in any way; in fact, to assert this would be absurd. But if we are to speak of a level of money prices that is "too high" or "too low," we must first state how the ideal level with which the actual level is compared has been established. It is in no way sufficient to show that the position of equilibrium is returned to after any disturbance, if the existence of this position of equilibrium is not first explained. Indubitably, this is the primary problem, and its solution leads directly to that of the other; without it, further inquiry must remain unfruitful, for the state of equilibrium can only be maintained by those forces which first established it and continue to reestablish it. If the circumstances of the loan market can provide no explanation of the genesis of the exchange ratio subsisting between money and other economic goods, then neither can they help to explain why this ratio does not alter. The objective exchange value of money is determined in the market where money is exchanged for commodities and commodities for money. To explain its determination is the task of the theory of the value of money. But Wicksell is of the opinion that "the laws of the exchange of commodities contain in themselves nothing that could determine the absolute level of money prices."^*40 This amounts to a denial of all possibility of scientific investigation in this sphere.

Helfferich also is of the opinion that there is an insurmountable obstacle in the way of applying the marginal-utility theory to the problem of money; for while the marginal-utility theory attempts to base the exchange value of goods on the degree of their utility to the individual, the degree of utility of money to the individual quite obviously depends on its exchange value, since money can have utility only if it has exchange value, and the degree of the utility is determined by the level of the exchange value. Money is valued subjectively according to the amount of consumable goods that can be obtained in exchange for it, or according to what other goods have to be given in order to obtain the money needed for making payments. The marginal utility of money to any individual, that is, 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.^*41

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. It is true that valuation of the monetary unit by the individual is possible only on the assumption that an exchange ratio already exists in the market between the money and other economic goods. Nevertheless, it is erroneous to deduce from this that a complete and satisfactory explanation of the determination of the objective exchange value of money cannot be provided by the marginal-utility theory. The fact that this theory is unable to explain the objective exchange value of money entirely by reference to its monetary utility; that to complete its explanation, as we were able to show, it is obliged to go back to that original exchange value which was based not on a monetary function at all but on other uses of the object that was to be used as money—this must not in any way be reckoned to the discredit of the theory, for it corresponds exactly to the nature and origin of the particular objective exchange value under discussion. To demand of a theory of the value of money that it should explain the exchange ratio between money and commodities solely with reference to the monetary function, and without the assistance of the element of historical continuity in the value of money, is to make demands of it that run quite contrary to its nature and its proper task.

The theory of the value of money as such can trace back the objective exchange value of money only to that point where it ceases to be the value of money and becomes merely the value of a commodity. At this point the theory must hand over all further investigation to the general theory of value, which will then find no further difficulty in the solution of the problem. It is true that the subjective valuation of money presupposes an existing objective exchange value; but the value that has to be presupposed is not the same as the value that has to be explained; what has to be presupposed is yesterday's exchange value, and it is quite legitimate to use it in an explanation of that of today. The objective exchange value of money which rules in the market today is derived from day'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 objective 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. But this point is not merely an instrumental concept of theory; it is an actual phenomenon of economic history, making its appearance at the moment when indirect exchange begins.

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. Just as the original starting point of the value of money was nothing but the result of subjective valuations, so also is the present-day value of money.

But Helfferich manages to bring forward yet another argument for the inapplicability of the marginal-utility theory to money. Looking at the economic system as a whole, it is clear that the notion of marginal utility rests on the fact that, given a certain quantity of goods, only certain wants can be satisfied and only a certain set of utilities provided. With given wants and a given set of means, the marginal degree of utility is determined also. According to the marginal-utility theory, this fixes the value of the goods in relation to the other goods that are offered as an equivalent in exchange, and fixes it in such a manner that that part of the demand that cannot be satisfied with the given supply is excluded by the fact that it is not able to offer an equivalent corresponding to the marginal utility of the good demanded. Now Helfferich objects that while the existence of a limited supply of any goods except money is in itself sufficient to imply the limitation of their utility also, this is not true of money. The utility of a given quantity of money depends directly upon the exchange value of the money, not only from the point of view of the individual, but also for society as a whole. The higher the value of the unit in relation to other goods, the greater will be the quantity of these other goods that can be paid for by means of the same sum of money. The value of goods in general results from the limitation of the possible utilities that can be obtained from a given supply of them, and while it is usually higher according to the degree of utility which is excluded by the limitation of supply, the total utility of the supply itself cannot be increased by an increase in its value; but in the case of money, the utility of a given supply can be increased at will by an increase in the value of the unit.^*42

The error in this argument is to be found in its regarding the utility of money from the point of view of the community instead of from that of the individual. Every valuation must emanate from somebody who is in a position to dispose in exchange of the object valued. Only those who have a choice between two economic goods are able to form a judgment as to value, and they do this by preferring the one to the other. If we start with valuations from the point of view of society as a whole, we tacitly assume the existence of a socialized economic organization in which there is no exchange and in which the only valuations are those of the responsible official body. Opportunities for valuation in such a society would arise in the control of production and consumption, as, for example, in deciding how certain production goods were to be used when there were alternative ways of using them. But in such a society there would be no room at all for money. Under such conditions, a common medium of exchange would have no utility and consequently no value either. It is therefore illegitimate to adopt the point of view of the community as a whole when dealing with the value of money. All consideration of the value of money must obviously presuppose a state of society in which exchange takes place and must take as its starting point individuals acting as independent economic agents within such a society,^*43 that is to say, individuals engaged in valuing things.

5 "Monetary" and "Nonmonetary" Influences Affecting the Objective Exchange Value of Money

Now, the first part of the problem of the value of money having been solved, it is at last possible for us to evolve a plan of further procedure. We no longer are concerned to explain the origin of the objective exchange value of money; this task has already been performed in the course of the preceding investigation. We now have to establish the laws which govern variations in existing exchange ratios between money and the other economic goods. This part of the problem of the value of money has occupied economists from the earliest times, although it is the other that ought logically to have been dealt with first. For this reason, as well as for many others, what has been done toward its elucidation does not amount to very much. Of course, this part of the problem is also much more complicated than the first part.

In investigations into the nature of changes in the value of money it is usual to distinguish between two sorts of determinants of the exchange ratio that connects money and other economic goods; those that exercise their effect on the money side of the ratio and those that exercise their effect on the commodity side. This distinction is extremely useful; without it, in fact, all attempts at a solution would have to be dismissed beforehand as hopeless. Nevertheless its true meaning must not be forgotten.

The exchange ratios between commodities—and the same is naturally true of the exchange ratios between commodities and money—result from determinants which affect both terms of the exchange ratio. But existing exchange ratios between goods may be modified by a change in determinants connected only with one of the two sets of exchanged objects. Although all the factors that determine the valuation of a good remain the same, its exchange ratio with another good may alter if the factors that determine the val uation of this second good alter. If of two persons I prefer A to B, this preference may be reversed, even though my feeling for A remains unchanged, if I contract a closer friendship with B. Similarly with the relationships between goods and human beings. He who today prefers the consumption of a cup of tea to that of a dose of quinine may make a contrary valuation tomorrow, even though his liking for tea has not diminished, if he has, say, caught a fever overnight. Whereas the factors that determine prices always affect both sets of the goods that are to be exchanged, those of them which merely modify existing prices may sometimes be restricted to one set of goods only.^*44

(II) Fluctuations in the Objective Exchange Value of Money
Evoked by Changes in the Ratio Between the
Supply of Money and the Demand for It

6 The Quantity Theory

That the objective exchange value of money as historically transmitted (der geschichtlich überkommene objektive Tauschwert des Geldes) is affected not only by the industrial use of the material from which it is made, but also by its monetary use, is a proposition which hardly any economist would nowadays deny. It is true that lay opinion was molded entirely by the contrary belief until very recent times. 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 jewelry, 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.^*45

Judgment upon the shortcomings of popular views about money and its value must be lenient, for even the attitude of science toward this problem has not always been free from error. Happily, the last few years have seen a gradual but definite change in popular monetary theory. It is now generally recognized that the value of money depends partly on its monetary function. This is due to the increased attention that has been devoted to questions of monetary policy since the commencement of the great controversy about the standards. The old theories proved unsatisfactory; it was not possible to explain phenomena such as those of the Austrian or Indian currency systems without invoking the assumption that the value of money originates partly in its monetary function. The naivety of the numerous writings which attacked this opinion and their complete freedom from the restraining influence of any sort of knowledge of the theory of value may occasionally lead the economist to regard them as unimportant; but they may at least claim to have performed the service of shaking deep-rooted prejudices and stimulating a general interest in the problem of prices. No doubt they are a gratifying indication of a growing interest in economic questions; if this is kept in mind, it is possible to think more generously of many erroneous monetary theories.

It is true that there has been no lack of attempts to explain the peculiar phenomena of modern monetary systems in other ways. But they have all been unsuccessful. Thus, in particular, Laughlin's theory comes to grief in failing to take account of the special aspects of the value of money that are associated with the specifically monetary function. Quite correctly, Laughlin stresses as the peculiar characteristic of money substitutes their constant and immediate convertibility into money.^*46 Nevertheless, he would seem to be mistaken on a fundamental point when he applies the name of token money to such currencies as the rupee from 1893 to 1899 and the Russian ruble and Austrian gulden at the time of the suspension of cash payments. He accounts for the fact that a piece of paper which is not immediately convertible into gold can have any value at all, by reference to the possibility that it will nevertheless someday be converted. He compares inconvertible paper money with the shares of a concern which is temporarily not paying any dividend but whose shares may nevertheless have a certain exchange value because of the possibility of future dividends. And he says that the fluctuations in the exchange value of such paper money are consequently based upon the varying prospects of its ultimate conversion.^*47

The error in this conclusion may be most simply demonstrated by means of an actual example. Let us select for this purpose the monetary history of Austria, which Laughlin also uses as an illustration. From 1859 onward the Austrian National Bank was released from the obligation to convert its notes on demand into silver, and nobody could tell when the state paper money issued in 1866 would be redeemed, or even if it would be redeemed at all. It was not until the later 1890s that the transition to metallic money was completed by the actual resumption of cash payments on the part of the Austro-Hungarian Bank.

Now Laughlin attempts to explain the value of the Austrian currency during this period by reference to the prospect of a future conversion of the notes into metallic commodity money. He finds the basis of its value, at first in an expectation that it would be converted into silver, and afterward in an expectation that it would be converted into gold, and traces the vicissitudes of its purchasing power to the varying chances of its ultimate conversion.^*48

The inadmissibility of this argument can be demonstrated in a striking fashion. In the year 1884—the year is chosen at random—the five percent Austrian government bonds were quoted on the Viennese Stock Exchange at an average rate of 95.81, or 4.19 percent below par. The quotation was in terms of Austrian paper gulden. The government bonds represented claims against the Austrian state bearing interest at five percent. Thus both the bonds and the notes were claims against the same debtor. It is true that these government bonds were not repayable, that is to say, not redeemable on the part of the creditor. Nevertheless, seeing that interest was paid on them, this could not prejudice their value in comparison with that of the non-interest-bearing currency notes, which also were not redeemable; furthermore, the interest on the bonds was payable in paper money, and, if the government redeemed them, it could do this also in paper money. In fact, the bonds in question were redeemed voluntarily in 1892, long before the currency notes were converted into gold. The question now arises: How could it come about that the government bonds, bearing interest at five percent, could be valued less highly than the non-interest-bearing currency notes? This could not possibly be attributed, say, to the fact that people hoped that the currency notes would be converted into gold before the bonds were redeemed. There was no suggestion of such an expectation. Quite another circumstance decided the matter.

The currency notes were common media of exchange—they were money—and consequently, besides the value that they possessed as claims against the state, they also had a value as money. It is beyond doubt that their value as claims alone would not have been an adequate basis even for a relatively large proportion of their actual exchange value. The date of repayment of the claims that were embodied in these notes was in fact quite uncertain, but in any case very distant. As claims, it was impossible for them to have a higher exchange value than corresponded to the then value of the expectation of their repayment. Now, after the cessation of free coinage of silver it was fairly obvious that the paper gulden (and incidentally the silver gulden) would not be converted at a rate appreciably in excess of the average rate at which it circulated in the period immediately preceding the conversion. In any case, after the legal determination of the conversion ratio by the Currency Regulation Law of August 2, 1892, it was settled that the conversion of the currency notes would not take place at any higher rate than this. How could it come about, then, that the gold value of the krone (the half-gulden) already fluctuated about this rate as early as the second half of the year 1892 although the date of conversion was then still quite unknown? Usually a claim to a fixed sum, the date of payment of which lies in the uncertain future, is valued considerably less highly than the sum to which it refers. To this question Laughlin's theory cannot offer an answer; only by taking account of the fact that the monetary function also contributes toward value is it possible to find a satisfactory explanation.

The attempts that have so far been made, to determine the quantitative significance of the forces emanating from the side of money that affect the exchange ratio existing between money and other economic goods, have followed throughout the line of thought of the quantity theory. This is not to say that all the exponents of the quantity theory had realized that the value of money is not determined solely by its nonmonetary, industrial employment, but also or even solely by its monetary function. Many quantity theorists have been of another opinion on this point and have believed that the value of money depends solely on the industrial employment of the monetary material. The majority have had no clear conception of the question at all; very few have approached its true solution. It is often hard to decide in which class certain of these authors should be placed; their phraseology is often obscure and their theories not seldom contradictory. All the same, let us suppose that all quantity theorists had recognized the significance of the monetary function in the determination of the value of the monetary material, and criticize the usefulness of their theory from this point of view.

When the determinants of the exchange ratios between economic goods were first inquired into, attention was early devoted to two factors whose importance for the pricing process was not to be denied. It was impossible to overlook the well-known connection between variations in the available quantity of goods and variations in prices, and the proposition was soon formulated that a good would rise in price if the available quantity of it diminished. Similarly, the importance of the total volume of transactions in the determination of prices was also realized. Thus, a mechanical theory of price determination was arrived at—the doctrine of supply and demand, which until very recently held such a prominent position in our science. Of all explanations of prices it is the oldest. We cannot dismiss it offhand as erroneous; the only valid objection to it is that it does not go back to the ultimate determinants of prices. It is correct or incorrect, according to the content given to the words demand and supply. It is correct, if account is taken of all the factors that motivate people in buying and selling. It is incorrect, if supply and demand are interpreted and compared in a merely quantitative sense.^*49

It was an obvious step to take this theory, that had been constructed to explain the reciprocal exchange ratios of commodities, and apply it to fluctuations in the relative values of commodities and money also. As soon as people became conscious of the fact of variations in the value of money at all, and gave up the naive conception of money as an invariable measure of value, they began to explain these variations also by quantitative changes in supply and demand.

It is true that the usual criticism of the quantity theory (often expressed with more resentment than is consonant with that objectivity which alone should be the distinctive mark of scientific investigation) had an easy task so far as it was leveled against the older, incomplete, version. It was not difficult to prove that the supposition that changes in the value of money must be proportionate to changes in the quantity of money, so that for example a doubling of the quantity of money would lead to a doubling of prices also, was not in accordance with facts and could not be theoretically established in any way whatever.^*50 It was still simpler to show the untenability of the naive version of the theory which regarded the total quantity of money and the total stock of money as equivalent.

But all these objections do not touch the essence of the doctrine. Neither can any sort of refutation or limitation of the quantity theory be deduced from the fact that a number of writers claim validity for it only on the assumption ceteris paribus; not even though they state further that this supposition never is fulfilled and never could be fulfilled.^*51 The assumption ceteris paribus is the self-evident appendage of every scientific doctrine and there is no economic law that can dispense with it.

Against such superficial criticism the quantity theory has been well able to defend itself triumphantly, and through the centuries, condemned by some and exalted as an indisputable truth by others, it has always been in the very center of scientific discussion. It has been dealt with in an immense literature, far beyond the power of any one person to master. It is true that the scientific harvest of these writings is but small. The theory has been adjudged "right" or "wrong," and statistical data (mostly incomplete and incorrectly interpreted) have been used both to "prove" and to "disprove" it—although sufficient care has seldom been taken to eliminate variations brought about by accidental circumstances. On the other hand, investigation on a basis of the theory of value has but seldom been attempted.

If we wish to arrive at a just appraisal of the quantity theory we must consider it in the light of the contemporary theories of value. 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.

If we make use in our discussion of only one fundamental idea contained in the quantity theory, the idea that a connection exists between variations in the value of money on the one hand and variations in the relations between the demand for money and the supply of it on the other hand, our reason is not that this is the most correct expression of the content of the theory from the historical point of view, but that it constitutes that core of truth in the theory which even the modern investigator can and must recognize as useful. Although the historian of economic theory may find this formulation inexact and produce quotations to refute it, he must nevertheless admit that it contains the correct expression of what is valuable in the quantity theory and usable as a cornerstone for a theory of the value of money.

Beyond this proposition, the quantity theory can provide us with nothing. Above all, it fails to explain the mechanism of variations in the value of money. Some of its expositors do not touch upon this question at all; the others employ an inadequate principle for dealing with it. Observation teaches us that certain relations of the kind suggested between the available stock of money and the need for money do in fact exist; the problem is to deduce these relations from the fundamental laws of value and so at last to comprehend their true significance.

7 The Stock of Money and the Demand for Money

The process, by which supply and demand are accommodated to each other until a position of equilibrium is established and both are brought into quantitative and qualitative coincidence, is the higgling of the market. But supply and demand are only the links in a chain of phenomena, one end of which has this visible manifestation in the market, while the other is anchored deep in the human mind. The intensity with which supply and demand are expressed, and consequently the level of the exchange ratio at which both coincide, depends on the subjective valuations of individuals. This is true, not only of the direct exchange ratios between economic goods other than money, but also of the exchange ratio between money on the one hand and commodities on the other.

For a long time it was believed that the demand for money was a quantity determined by objective factors and independently of subjective considerations. It was thought that the demand for money in an economic community was determined, on the one hand by the total quantity of commodities that had to be paid for during a given period, and on the other hand by the velocity of circulation of the money. There is an error in the very starting point of this way of regarding the matter, which was first successfully attacked by Menger.^*52 It is inadmissible to begin with the demand for money of the community. The individualistic economic community as such, which is the only sort of community in which there is a demand for money, is not an economic agent. It demands money only insofar as its individual members demand money. The demand for money of the economic community is nothing but the sum of the demands for money of the individual economic agents composing it. But for individual economic agents it is impossible to make use of the formula: total volume of transactions ÷ velocity of circulation. If we wish to arrive at a description of the demand for money of an individual we must start with the considerations that influence such an individual in receiving and paying out money.

Every economic agent is obliged to hold a stock of the common medium of exchange sufficient to cover his probable business and personal requirements. The amount that will be required depends upon individual circumstances. It is influenced both by the custom and habits of the individual and by the organization of the whole social apparatus of production and exchange.

But all of these objective factors always affect the matter only as motivations of the individual. They are never capable of a direct influence upon the actual amount of his demand for money. Here, as in all departments of economic life, it is the subjective valuations of the separate economic agents that alone are derisive. The store of purchasing power held by two such agents whose objective economic circumstances were identical might be quite different if the advantages and disadvantages of such a store were estimated differently by the different agents.

The cash balance held by an individual need by no means consist entirely of money. If secure claims to money, payable on demand, are employed commercially as substitutes for money, being tendered and accepted in place of money, then individuals' stores of money can be entirely or partly replaced by a corresponding store of these substitutes. In fact, for technical reasons (such, for example, as the need for having money of various denominations on hand) this may sometimes prove an unavoidable necessity. It follows that we can speak of a demand for money in a broader and in a narrower sense. The former comprises the entire demand of an individual for money and money substitutes; the second, merely his demand for money proper. The former is determined by the will of the economic agent in question. The latter is fairly independent of individual influences, if we disregard the question of denomination referred to above. Apart from this, the question whether a greater or smaller part of the cash balance held by an individual shall consist of money substitutes is only of importance to him when he has the opportunity of acquiring money substitutes which bear interest, such as interest-bearing banknotes—a rare case—or bank deposits. In all other cases it is a matter of complete indifference to him.

The individual's demand and stock of money are the basis of the demand and stock in the whole community. So long as there are no money substitutes in use, the social demand for money and the social stock of money are merely the respective sums of the individual demands and stocks. But this is changed with the advent of money substitutes. The social demand for money in the narrower sense is no longer the sum of the individual demands for money in the narrower sense, and the social demand for money in the broader sense is by no means the sum of the individual demands for money in the broader sense. Part of the money substitutes functioning as money in the cash holdings of individuals are "covered" by sums of money held as "redemption funds" at the place where the money substitutes are cashable, which is usually, although not necessarily, the issuing concern. We shall use the term money certificates for those money substitutes that are completely covered by the reservation of corresponding sums of money, and the term fiduciary media^*53 for those which are not covered in this way. The suitability of this terminology, which has been chosen with regard to the problem to be dealt with in the third part of the present work, must be demonstrated in that place. It is not to be understood in the light of banking technique or in a juristic sense; it is merely intended to serve the ends of economic argument.

Only in the rarest cases can any particular money substitutes be immediately assigned to the one or the other group. That is possible only for those money substitutes of which the whole species is either entirely covered by money or not covered by money at all. In the case of all other money substitutes, those the total quantity of which is partly covered by money and partly not covered by money, only an imaginary ascription of an aliquot part to each of the two groups can take place. This involves no fresh difficulty. If, for example, there are banknotes in circulation one-third of the quantity of which is covered by money and two-thirds not covered, then each individual note is to be reckoned as two-thirds fiduciary medium and one-third money certificate. It is thus obvious that a community's demand for money in the broader sense cannot be the sum of the demands of individuals for money and money substitutes, because to reckon in the demand for money certificates as well as that for the money that serves as a cover for them as the banks and elsewhere is to count the same amount twice over. A community's demand for money in the broader sense is the sum of the demands of the individual economic agents for money proper and fiduciary media (including the demand for cover). And a community's demands for money in the narrower sense are the sum of the demands of the individual economic agents for money and money certificates (this time not including cover).

In this part we shall ignore the existence of fiduciary media and assume that the demands for money of individual economic agents can be satisfied merely by money and money certificates, and consequently that the demand for money of the whole economic community can be satisfied merely by money proper.^*54 The third part of this book is devoted to an examination of the important and difficult problems arising from the creation and circulation of fiduciary media.

The demand for money and its relations to the stock of money form the starting point for an explanation of fluctuations in the objective exchange value of money. Not to understand the nature of the demand for money is to fail at the very outset of any attempt to grapple with the problem of variations in the value of money. If we start with a formula that attempts to explain the demand for money from the point of view of the community instead of from that of the individual, we shall fail to discover the connection between the stock of money and the subjective valuations of individuals—the foundation of all economic activity. But on the other hand, this problem is solved without difficulty if we approach the phenomena from the individual agent's point of view.

No longer explanation is necessary, of the way in which an individual will behave in the market when his demand for money exceeds his stock of it. He who has more money on hand than he thinks he needs, will buy, in order to dispose of the superfluous stock of money that lies useless on his hands. If he is an entrepreneur, he will possibly enlarge his business. If this use of the money is not open to him, he may purchase interest-bearing securities; or possibly he may decide to purchase consumption goods. But in any case, he expresses by a suitable behavior in the market the fact that he regards his reserve of purchasing power as too large.

And he whose demand for money is less than his stock of it will behave in an exactly contrary fashion. If an individual's stock of money diminishes (his property or income remaining the same), then he will take steps to reach the desired level of reserve purchasing power by suitable behavior in making sales and purchases. A shortage of money means a difficulty in disposing of commodities for money. He who is obliged to dispose of a commodity by way of exchange will prefer to acquire some of the common medium of exchange for it, and only when this acquisition involves too great a sacrifice will he be content with some other economic good, which will indeed be more marketable than that which he wishes to dispose of but less marketable than the common medium of exchange. Under the present organization of the market, which leaves a deep gulf between the marketability of money on the one hand and the marketability of other economic goods on the other hand, nothing but money enters into consideration at all as a medium of exchange. Only in exceptional circumstances is any other economic good pressed into this service. In the case mentioned, therefore, every seller will be willing to accept a smaller quantity of money than he otherwise would have demanded, so as to avoid the fresh loss that he would have to suffer in again exchanging the commodity that he has acquired, which is harder to dispose of than money, for the commodity that he actually requires for consumption.

The older theories, which started from an erroneous conception of the social demand for money, could never arrive at a solution of this problem. Their sole contribution is limited to paraphrases of the proposition that an increase in the stock of money at the disposal of the community while the demand for it remains the same decreases the objective exchange value of money, and that an increase of the demand with a constant available stock has the contrary effect, and so on. By a flash of genius, the formulators of the quantity theory had already recognized this. We cannot by any means call it an advance when the formula giving the amount of the demand for money (volume of transactions ÷ velocity of circulation) was reduced to its elements, or when the attempt was made to give exact precision to the idea of a stock of money, so long as this occurred under a misapprehension of the nature of fiduciary media and of clearing transactions. No approach whatever was made toward the central problem of this part of the theory of money so long as theorists were unable to show the way in which subjective valuations are affected by variations in the ratio between the stock of money and the demand for money. But this task was necessarily beyond the power of these theories; they break down at the crucial point.^*55

Recently, Wieser has expressed himself against employing the "collective concept of the demand for money" as the starting point for a theory of fluctuations in the objective exchange value of money. He says that in an investigation of the value of money we are not concerned with the total demand for money. The demand for money to pay taxes with, for example, does not come into consideration, for these payments do not affect the value of money but only transfer purchasing power from those who pay the taxes to those who receive them. In the same way, capital and interest payments in loan transactions and the making of gifts and bequests merely involve a transference of purchasing power between persons and not an augmentation or diminution of it. A functional theory of the value of money must, in stating its problem, have regard only to those factors by which the value of money is determined. The value of money is determined in the process of exchange. Consequently the theory of the value of money must take account only of those quantifies which enter into the process of exchange.^*56

But these objections of Wieser's are not only rebutted by the fact that even the surrender of money in paying taxes, in making capital and interest payments, and in giving presents and bequests, falls into the economic category of exchange. Even if we accept Wieser's narrow definition of exchange, we must still oppose his argument. It is not a peculiarity of money that its value (Wieser obviously means its objective exchange value) is determined in the process of exchange; the same is true of all other economic goods. For all economic goods it must therefore be correct to say that the theory of value has to investigate only certain quantities, namely, only those that are involved in the process of exchange. But there is no such thing in economics as a quantity that is not involved in the process of exchange. From the economic point of view, a quantity has no other relationships than those which exercise some influence upon the valuations of individuals concerned in some process or other of exchange.

This is true, even if we admit that value only arises in connection with exchange in the narrow sense intended by Wieser. But those who participate in exchange transactions, and consequently desire to acquire or dispose of money do not value the monetary unit solely with regard to the fact that they can use it in other acts of exchange (in Wieser's narrower sense of the expression), but also because they require money in order to pay taxes, to transfer borrowed capital and pay interest, and to make presents. They consider the level of their purchasing-power reserves with a view to the necessity of having money ready for all these purposes, and their judgment as to the extent of their requirements for money is what decides the demand for money with which they enter the market.

8 The Consequences of an Increase in the Quantity of Money While the Demand for Money Remains Unchanged or Does Not Increase to the Same Extent

Those variations in the ratio between the individual's demand for money and his stock of it that arise from purely individual causes cannot as a rule have a very large quantitative influence in the market. In most cases they will be entirely, or at least partly, compensated by contrary variations emanating from other individuals in the market. But a variation in the objective exchange value of money can arise only when a force is exerted in one direction that is not canceled by a counteracting force in the opposite direction. If the causes that alter the ratio between the stock of money and the demand for it from the point of view of an individual consist merely in accidental and personal factors that concern that particular individual only, then, according to the law of large numbers, it is likely that the forces arising from this cause, and acting in both directions in the market, will counterbalance each other. The probability that the compensation will be complete is the greater, the more individual economic agents there are.

It is otherwise when disturbances occur in the community as a whole, of a kind to alter the ratio existing between the individual's stock of money and his demand for it. Such disturbances, of course, cannot have an effect except by altering the subjective valuations of the individual; but they are social economic phenomena in the sense that they influence the subjective valuations of a large number of individuals, if not simultaneously and in the same degree, at least in the same direction, so that there must necessarily be some resultant effect on the objective exchange value of money.

In the history of money a particularly important part has been played by those variations in its objective exchange value that have arisen in consequence of an increase in the stock of money while the demand for it has remained unchanged or has at least not increased to the same extent. These variations, in fact, were what first attracted the attention of economists; it was in order to explain them that the quantity theory of money was first propounded. All writers have dealt most thoroughly with them. It is perhaps justifiable, therefore, to devote special attention to them and to use them to illuminate certain important theoretical points.

In whatever way we care to picture to ourselves the increase in the stock of money, whether as arising from increased production or importation of the substance of which commodity money is made, or through a new issue of fiat or credit money, the new money always increases the stock of money at the disposal of certain individual economic agents. An increase in the stock of money in a community always means an increase in the money incomes of a number of individuals; but it need not necessarily mean at the same time an increase in the quantity of goods that are at the disposal of the community, that is to say, it need not mean an increase in the national dividend. An increase in the amount of fiat or credit money is only to be regarded as an increase in the stock of goods at the disposal of society if it permits the satisfaction of a demand for money which would otherwise have been satisfied by commodity money instead, since the material for the commodity money would then have had to be procured by the surrender of other goods in exchange or produced at the cost of renouncing some other sort of production. If, on the other hand, the nonexistence of the new issue of fiat or credit money would not have involved an increase in the quantity of commodity money, then the increase of money cannot be regarded as an increase of the income or wealth of society.

An increase in a community's stock of money always means an increase in the amount of money held by a number of economic agents, whether these are the issuers of fiat or credit money or the producers of the substance of which commodity money is made. For these persons, the ratio between the demand for money and the stock of it is altered; they have a relative superfluity of money and a relative shortage of other economic goods. The immediate consequence of both circumstances is that the marginal utility to them of the monetary unit diminishes. This necessarily influences their behavior in the market. They are in a stronger position as buyers. They will now express in the market their demand for the objects they desire more intensively than before; they are able to offer more money for the commodities that they wish to acquire. It will be the obvious result of this that the prices of the goods concerned will rise, and that the objective exchange value of money will fall in comparison.

But this rise of prices will by no means be restricted to the market for those goods that are desired by those who originally have the new money at their disposal. In addition, those who have brought these goods to market will have their incomes and their proportionate stocks of money increased and, in their turn, will be in a position to demand more intensively the goods they want, so that these goods will also rise in price. Thus the increase of prices continues, having a diminishing effect, until all commodities, some to a greater and some to a lesser extent, are reached by it.^*57

The increase in the quantity of money does not mean an increase of income for all individuals. On the contrary, those sections of the community that are the last to be reached by the additional quantity of money have their incomes reduced, as a consequence of the decrease in the value of money called forth by the increase in its quantity; this will be referred to later. The reduction in the income of these classes now starts a countertendency, which opposes the tendency to a diminution of the value of money due to the increase of income of the other classes, without being able to rob it completely of its effect.

Those who hold the mechanical version of the quantity theory will be the more inclined to believe that the increase in the quantity of money must eventually lead to a uniform increase in the prices of all economic goods, the less clear their concept is of the way in which the determination of prices is affected by it. Thorough comprehension of the mechanism by means of which the quantity of money affects the prices of commodities makes their point of view altogether untenable. Since the increased quantity of money is received in the first place by a limited number of economic agents only and not by all, the increase of prices at first embraces only those goods that are demanded by these persons; further, it affects these goods more than it afterward affects any others. When the increase of prices spreads farther, if the increase in the quantity of money is only a single transient phenomenon, it will not be possible for the differential increase of prices of these goods to be completely maintained; a certain degree of adjustment will take place. But there will not be such a complete adjustment of the increases that all prices increase in the same proportion. The prices of commodities after the rise of prices will not bear the same relation to each other as before its commencement; the decrease in the
