Money and the myth of barter
In the beginning, there was barter. Then, and forever after, there was money.
That’s the myth every student of economics learns, that money grows out of barter. The idea is that monetary exchange solves the problem of the double coincidence of wants – that a person who is interested in trading needs to find someone who wants what they have and has what they want. Money makes trade much easier, so the story goes, and thus becomes a remarkable example of both human ingenuity and economic progress.
As Ilana Strauss  explains, the fact is that the story is false. Human beings did not invent money to solve the difficulties of barter exchange. Barter turns out to be a historical myth: various anthropologists have pointed out that this barter economy has never been witnessed as researchers have travelled to undeveloped parts of the globe. ‘No example of a barter economy, pure and simple, has ever been described, let alone the emergence from it of money,’ wrote the Cambridge anthropologist Prof Caroline Humphrey in a 1985 paper . ‘All the available ethnography suggests that there never has been such a thing’.
Humphrey isn’t alone. A range of other academics, including French sociologist Marcel Mauss and Cambridge political economist Geoffrey Ingham, have long espoused similar arguments.
When barter has appeared, it wasn’t as part of a purely barter economy, and money didn’t emerge from it – rather, it emerged from money. After Rome fell, for instance, Europeans used barter as a substitute for the Roman currency people had gotten used to. ‘In most of the cases we know about, [barter] takes place between people who are familiar with the use of money, but for one reason or another, don’t have a lot of it around,’ explains Prof David Graeber, an anthropologist at the London School of Economics. ”
A good example is the kind of exchange described by Fibonacci in his Liber Abbaci. He devoted the 9th chapter to “barter of merchandise and similar things”. But it wasn’t pre-monetary barter. Instead, as Randy Schwarz  explains: A barter was often recorded as such in a register or account book, as if actual coins had been exchanged, when in fact no coins at all were involved.
Because coins were still scarce, the widespread custom among merchants was to set a commodity barter price by ‘marking up’ the cash price by a certain percentage. The two barterers had to agree on the mark-up rate ahead of time, or else one would feel cheated.”
In other words, this was exchange that took money as the unit of account but, because coins were scarce, it took the form of the direct exchange of goods – say, wool for cloth.
And there are many other examples in the historical and anthropological record of forms of exchange that precluded money – including centralization and redistribution, gifts, potlatch, trade at the edges of and between non-monetary societies, and so on. But there was no original barter economy, which was then surpassed by the use of money.
That’s a myth that began with Adam Smith :
“But when the division of labour first began to take place, this power of exchanging must frequently have been very much clogged and embarrassed in its operations. One man, we shall suppose, possesses more of a certain commodity than he himself has occasion for, while another has less. The former, consequently, would be glad to dispose of; and the latter to purchase, a part of this superfluity. But if this latter should chance to have nothing that the former stands in need of, no exchange can be made between them. The butcher has more meat in his shop than he himself can consume, and the brewer and the baker would each of them be willing to purchase a part of it. But they have nothing to offer in exchange, except the different
productions of their respective trades, and the butcher is already provided with all the bread and beer which he has immediate occasion for. No exchange can, in this case, be made between them. He cannot be their merchant, nor they his customers; and they are all of them thus mutually less serviceable to one another.
In order to avoid the inconveniency of such situations, every prudent man in every period of society, after the first establishment of the division of labour, must naturally have endeavoured to manage his affairs in such a manner, as to have at all times by him, besides the peculiar produce of his own industry, a certain quantity of some one commodity or other, such as he imagined few people would be likely to refuse in exchange for the produce of their industry. Many different commodities, it is probable, were successively both thought of and employed for this purpose. In the rude ages of society, cattle are said to have been the common instrument of commerce; and, though they must have been a most inconvenient one, yet, in old times, we find things were frequently valued according to the number of cattle which had been given in exchange for them.
“The armour of Diomede, says Homer, cost only nine oxen; but that of Glaucus cost a hundred oxen. Salt is said to be the common instrument of commerce and exchanges in Abyssinia; a species of shells in some parts of the coast of India; dried cod at Newfoundland; tobacco in Virginia; sugar in some of our West India colonies; hides or dressed leather in some other countries; and there is at this day a village in Scotland, where it is not uncommon, I am told, for a workman to carry nails instead of money to the baker’s shop or the ale- house.
“In all countries, however, men seem at last to have been determined by irresistible reasons to give the preference, for this employment, to metals above every other commodity. Metals can not only be kept with as little loss as any other commodity, scarce any thing being less perishable than they are, but they can likewise, without any loss, be divided into any number of parts, as by fusion those parts can easily be re-united again; a quality which no other equally durable commodities possess, and which, more than any other quality, renders them fit to be the instruments of commerce and circulation. The man who wanted to buy salt, for example, and had nothing but cattle to give in exchange for it, must have been obliged to buy salt to the value of a whole ox, or a whole sheep, at a time. He could seldom buy less than this, because what he was to give for it could seldom be divided without loss; and if he had a mind to buy more, he must, for the same reasons, have been obliged to buy double or triple the quantity, the value, to wit, of two or three oxen, or of two or three sheep. If, on the contrary, instead of sheep or oxen, he had metals to exchange for it, he could easily proportion the quantity of the metal to the precise quantity of the commodity which he had immediate occasion for. ”
It’s a myth that continues to be taught to hundreds of thousands of economics students every semester.
It occupies much the same position as the Robinson Crusoe story. In both cases, it’s a myth that starts with self- interested individuals who make decisions – to trade with money or to enter into a division of labour – that, at one and the same time, benefit themselves and society as a whole.
But, of course, there are many things missing from these mythical origin stories. There’s no exploitation or instability; no debt, unequal power, or state coercion; no social relations or embeddedness of the economy within society.
Instead, what mainstream economics offers starting with Smith, and continues to offer studies today, is a story about the mythical – unreal, historical – origins of capitalism.
The sooner we recognize those stories for what they are, the sooner we can get on with the business of imagining and creating alternative economic institutions.
