Barter is direct exchange: goods traded against goods, with no money serving as a medium. It matters in Austrian theory chiefly for what it cannot do, since the difficulties of direct exchange are what explain the emergence of money.
The double coincidence of wants
Under barter an exchange requires that each party hold precisely what the other wants and want precisely what the other holds. That coincidence is rare, and it becomes rarer as the division of labor deepens: a specialist produces one thing and needs thousands, so the more productive the arrangement, the harder direct exchange becomes.
Two further limits compound it. Many goods are not divisible, so a trader with one ox and a need for a week's grain cannot make the trade at any ratio. And under barter every good has an exchange ratio against every other, so the number of ratios a trader must know grows roughly with the square of the number of goods, where under money each good has just one price.
How money emerges from barter
Carl Menger used these difficulties to explain the origin of money without appealing to invention or decree. A trader who cannot find a direct counterparty can improve his position by accepting, in exchange, a good he does not want himself, provided it is more saleable than what he currently holds, since it will be easier to trade on. Each trader doing this converges on the most saleable goods, and those goods thereby become general media of exchange.
No one has to intend money for money to appear. It is the standard illustration of spontaneous order, and it is why Austrians regard money as a market phenomenon rather than a creation of the state.[1]
Ludwig von Mises built his regression theorem on the same starting point: money's purchasing power today traces back through yesterday's purchasing power to a point at which the commodity was valued for its non-monetary uses in direct exchange. Barter is thus the historical anchor that keeps the theory of money's value from circularity.
Whether barter economies existed
Whether whole societies ever ran on barter is disputed by anthropologists, several of whom argue that credit and customary obligation, rather than spot barter, preceded coinage.[2] The dispute bears less on the theory than is sometimes supposed: Menger's argument is about the logic by which a more saleable good is preferred in exchange, and it does not require that a barter-only society ever existed as a historical stage.
Barter also reappears where money fails. Under hyperinflation, and where exchange controls or price controls make monetary transactions unattractive, trade reverts toward direct exchange, and the resulting loss of specialization is a standard measure of the damage done.
