Carl Menger - On the Origin of Money

 VI. On the Genesis of Media of Exchange. 

It has long been the subject of universal remark in centres of exchange, that for certain commodities there existed a greater, more constant, and more effective demand than for other commodities less desirable in certain respects, the former being such as correspond to a want on the part of those able and willing to traffic, which is at once universal and, by reason of the relative scarcity of the goods in question, always imperfectly satisfied. And further, that the person who wishes to acquire certain definite goods in exchange for his own is in a more favourable position, if he brings commodities of this kind to market, than if he visits the markets with goods which cannot display such advantages, or at least not in the same degree. Thus equipped he has the prospect of acquiring such goods as he finally wishes to obtain, not only with greater ease and security, but also, by reason of the steadier and more prevailing demand for his own commodities, at prices corresponding to the general economic situation -- at economic prices. Under these circumstances, when any one has brought goods not highly saleable to market, the idea uppermost in his mind is to exchange them, not only for such as he happens to be in need of, but, if this cannot be effected directly, for other goods also, which, while he did not want them himself, were nevertheless more saleable than his own. By so doing he certainly does not attain at once the final object of his trafficking, to wit, the acquisition of goods needful to himself. Yet he draws nearer to that object. By the devious way of a mediate exchange, he gains the prospect of accomplishing his purpose more surely and economically than if he had confined himself to direct exchange. Now in point of fact this seems everywhere to have been the case. Men have been led, with increasing knowledge of their individual interests, each by his own economic interests, without convention, without legal compulsion, nay, even without any regard to the common interest, to exchange goods destined for exchange (their "wares") for other goods equally destined for exchange, but more saleable.
With the extension of traffic in space and with the expansion over ever longer intervals of time of prevision for satisfying material needs, each individual would learn, from his own economic interests, to take good heed that he bartered his less saleable goods for those special commodities which displayed, beside the attraction of being highly saleable in the particular locality, a wide range of saleableness both in time and place. These wares would be qualified by their costliness, easy transportability, and fitness for preservation (in connection with the circumstance of their corresponding to a steady and widely distributed demand), to ensure to the possessor a power, not only 'here' and 'now' but as nearly as possible unlimited in space and time generally, over all other market-goods at economic prices.
And so it has come to pass, that as man became increasingly conversant with these economic advantages, mainly by an insight become traditional, and by the habit of economic action, those commodities, which relatively to both space and time are most saleable, have in every market become the wares, which it is not only in the interest of every one to accept in exchange for his own less saleable goods, but which also are those he actually does readily accept. And their superior saleableness depends only upon the relatively inferior saleableness of every other kind of commodity, by which alone they have been able to become generally acceptable media of exchange.
It is obvious how highly significant a factor is habit in the genesis of such generally serviceable means of exchange. It lies in the economic interest of each trafficking individual to exchange less saleable for more saleable commodities. But the willing acceptance of the medium of exchange presupposes already a knowledge of these interest on the part of those economic subjects who are expected to accept in exchange for their wares a commodity which in and by itself is perhaps entirely useless to them. It is certain that this knowledge never arises in every part of a nation at the same time. It is only in the first instance a limited number of economic subjects who will recognize the advantage in such procedure, an advantage which, in and by itself, is independent of the general recognition of a commodity as a medium of exchange, inasmuch as such an exchange, always and under all circumstances, brings the economic unit a good deal nearer to his goal, to the acquisition of useful things of which he really stands in need. But it is admitted, that there is no better method of enlightening any one about his economic interests than that he perceive the economic success of those who use the right means to secure their own. Hence it is also clear that nothing may have been so favourable to the genesis of a medium of exchange as the acceptance, on the part of the most discerning and capable economic subjects, for their own economic gain, and over a considerable period of time, of eminently saleable goods in preference to all others. In this way practice and a habit have certainly contributed not a little to cause goods, which were most saleable at any time, to be accepted not only by many, but finally by all, economic subjects in exchange for their less saleable goods; and not only so, but to be accepted from the first with the intention of exchanging them away again. Goods which had thus become generally acceptable media of exchange were called by the Germans Geld, from gelten, i.e. to pay, to perform, while other nations derived their designation for money mainly from the substance used, the shape of the coin,  or even from certain kinds of coin.  It is not impossible for media of exchange, serving as they do the commonweal in the most emphatic sense of the word, to be instituted also by way of legislation, like other social institutions. But this is neither the only, nor the primary mode in which money has taken its origin. This is much more to be traced in the process depicted above, notwithstanding the nature of that process would be but very incompletely explained if we were to call it 'organic' or denote money as something 'primordial', or 'primaeval growth', and so forth. Putting aside assumptions which are historically unsound, we can only come fully to understand the origin of money by learning to view the establishment of the social procedure, with which we are dealing, as the spontaneous outcome, the unpremeditated resultant, of particular, individual efforts of the members of a society, who have little by little worked their way to a discrimination of the different degrees of saleableness in commodities.
