Debt (5 page)

Why the discrepancy?
Some of it is just the nature of the evidence: coins are preserved in the archeological record; credit arrangements usually are not. Still, the problem runs deeper. The existence of credit and debt has always been something of a scandal for economists, since it’s almost impossible to pretend that those lending and borrowing money are acting on purely “economic” motivations (for instance, that a loan to a stranger is the same as a loan to one’s cousin); it seems important, therefore, to begin the story of money in an imaginary world from which credit and debt have been entirely erased. Before we can apply the tools of anthropology to reconstruct the real history of money, we need to understand what’s wrong with the conventional account.
Economists generally speak of three functions of money: medium of exchange, unit of account, and store of value. All economic textbooks treat the first as primary. Here’s a fairly typical extract from
Economics
, by Case, Fair, Gärtner, and Heather (1996)
:
Money is vital to the working of a market economy. Imagine what life would be like without it. The alternative to a monetary economy is barter, people exchanging goods and services for other goods and services directly instead of exchanging via the medium of money.
How does a barter system work? Suppose you want croissants, eggs and orange juice for breakfast. Instead of going to the grocer’s and buying these things with money, you would have to find someone who has these items and is willing to trade them. You would also have to have something the baker, the orange juice purveyor and the egg vendor want. Having pencils to trade will do you no good if the baker and the orange juice and egg sellers do not want pencils.
A barter system requires a double coincidence of wants for trade to take place. That is, to effect a trade, I need not only have to find someone who has what I want, but that person must also want what I have. Where the range of traded goods is small, as it is in relatively unsophisticated economies, it is
not difficult to find someone to trade with, and barter is often used.

This latter point is questionable, but it’s phrased in so vague a way that it would be hard to disprove.
In a complex society with many goods, barter exchanges involve an intolerable amount of effort. Imagine trying to find people who offer for sale all the things you buy in a typical trip to the grocer’s, and who are willing to accept goods that you have to offer in exchange for their goods.
Some agreed-upon medium of exchange (or means of payment) neatly eliminates the double coincidence of wants problem.

It’s important to emphasize that this is not presented as something that actually happened, but as a purely imaginary exercise. “To see that society benefits from a medium of exchange” write Begg, Fischer and Dornbuch (
Economics
, 2005), “imagine a barter economy.” “Imagine the difficulty you would have today,” write Maunder, Myers, Wall, and Miller (
Economics Explained
, 1991), “if you had to exchange your labor directly for the fruits of someone else’s labor.” “Imagine,” write Parkin and King (
Economics
, 1995), “you have roosters, but you want roses.”

One could multiply examples endlessly. Just about every economics textbook employed today sets out the problem the same way. Historically, they note, we know that there was a time when there was no money. What must it have been like? Well, let us imagine an economy something like today’s, except with no money. That would have been decidedly inconvenient! Surely, people must have invented money for the sake of efficiency.
The story of money for economists always begins with a fantasy world of barter. The problem is where to locate this fantasy in time and space: Are we talking about cave men, Pacific Islanders, the American frontier? One textbook, by economists Joseph Stiglitz and John Driffill, takes us to what appears to be an imaginary New England or Midwestern town:
One can imagine an old-style farmer bartering with the blacksmith, the tailor, the grocer, and the doctor in his small town. For simple barter to work, however, there must be a double coincidence of wants … Henry has potatoes and wants shoes, Joshua has an extra pair of shoes and wants potatoes. Bartering
can make them both happier. But if Henry has firewood and Joshua does not need any of that, then bartering for Joshua’s shoes requires one or both of them to go searching for more people in the hope of making a multilateral exchange. Money provides a way to make multilateral exchange much simpler. Henry sells his firewood to someone else for money and uses the money to buy Joshua’s shoes.

Again this is just a make-believe land much like the present, except with money somehow plucked away. As a result it makes no sense: Who in their right mind would set up a grocery in such a place? And how would they get supplies? But let’s leave that aside. There is a simple reason why everyone who writes an economics textbook feels they have to tell us the same story. For economists, it is in a very real sense the most important story ever told. It was by telling it, in the significant year of 1776, that Adam Smith, professor of moral philosophy at the University of Glasgow, effectively brought the discipline of economics into being.
He did not make up the story entirely out of whole cloth. Already in 330 bc, Aristotle was speculating along vaguely similar lines in his treatise on politics. At first, he suggested, families must have produced everything they needed for themselves. Gradually, some would presumably have specialized, some growing corn, others making wine, swapping one for the other.

Money, Aristotle assumed, must have emerged from such a process. But, like the medieval schoolmen who occasionally repeated the story, Aristotle was never clear as to how.

In the years after Columbus, as Spanish and Portuguese adventurers were scouring the world for new sources of gold and silver, these vague stories disappear. Certainly no one reported discovering a land of barter. Most sixteenth- and seventeenth-century travelers in the West Indies or Africa assumed that all societies would necessarily have their own forms of money, since all societies had governments and all governments issued money.
7
Adam Smith, on the other hand, was determined to overturn the conventional wisdom of his day. Above all, he objected to the notion that money was a creation of government. In this, Smith was the intellectual heir of the Liberal tradition of philosophers like John Locke, who had argued that government begins in the need to protect private property and operated best when it tried to limit itself to that function. Smith expanded on the argument, insisting that property, money and markets not only existed before political institutions but were the very foundation of human society. It followed that insofar as government
should play any role in monetary affairs, it should limit itself to guaranteeing the soundness of the currency. It was only by making such an argument that he could insist that economics is itself a field of human inquiry with its own principles and laws—that is, as distinct from, say ethics or politics.
Smith’s argument is worth laying out in detail because it is, as I say, the great founding myth of the discipline of economics.
What, he begins, is the basis of economic life, properly speaking? It is “a certain propensity in human nature … the propensity to truck, barter, and exchange one thing for another.” Animals don’t do this. “Nobody,” Smith observes, “ever saw a dog make a fair and deliberate exchange of one bone for another with another dog.”

But humans, if left to their own devices, will inevitably begin swapping and comparing things. This is just what humans do. Even logic and conversation are really just forms of trading, and as in all things, humans will always try to seek their own best advantage, to seek the greatest profit they can from the exchange.

It is this drive to exchange, in turn, which creates that division of labor responsible for all human achievement and civilization. Here the scene shifts to another one of those economists’ faraway fantasylands—it seems to be an amalgam of North American Indians and Central Asian pastoral nomads:

In a tribe of hunters or shepherds a particular person makes bows and arrows, for example, with more readiness and dexterity than any other. He frequently exchanges them for cattle or for venison with his companions; and he finds at last that he can in this manner get more cattle and venison, than if he himself went to the field to catch them. From a regard to his own interest, therefore, the making of bows and arrows grows to be his chief business, and he becomes a sort of armourer. Another excels in making the frames and covers of their little huts or moveable houses. He is accustomed to be of use in this way to his neighbours, who reward him in the same manner with cattle and with venison, till at last he finds it his interest to dedicate himself entirely to this employment, and to become a sort of house-carpenter. In the same manner a third becomes a smith or a brazier; a fourth a tanner or dresser of hides or skins, the principal part of the clothing of savages …
It’s only once we have expert arrow-makers, wigwam-makers, and so on that people start realizing there’s a problem. Notice how, as in
so many examples, we have a tendency to slip from imaginary savages to small-town shopkeepers.
But when the division of labor 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, has 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 …
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 labor, must naturally have endeavored 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 that few people would be likely to refuse in exchange for the produce of their industry.
11
So everyone will inevitably start stockpiling something they figure that everyone else is likely to want. This has a paradoxical effect, because at a certain point, rather than making that commodity less valuable (since everyone already has some) it becomes more valuable (because it becomes, effectively, currency):
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.

Eventually, of course, at least for long-distance trade, it all boils down to precious metals, since these are ideally suited to serve as currency, being durable, portable, and able to be endlessly subdivided into identical portions.
Different metals have been made use of by different nations for this purpose. Iron was the common instrument of commerce among the ancient Spartans; copper among the ancient Romans; and gold and silver among all rich and commercial nations.
Those metals seem originally to have been made use of for this purpose in rude bars, without any stamp or coinage …
The use of metals in this rude state was attended with two very considerable inconveniencies; first with the trouble of weighing; and, secondly, with that of assaying them. In the precious metals, where a small difference in the quantity makes a great difference in the value, even the business of weighing, with proper exactness, requires at least very accurate weights and scales. The weighing of gold in particular is an operation of some nicety …
