BARTER EXCHANGE: A method of trading goods, commodities, or services, directly for one another without the use of money. In a barter exchange one good is traded directly for another. This sort of exchange ultimately requires a double coincidence of wants, meaning that each trader has what the other trader wants and wants what the other has. Without a double coincidence of wants the exchange process can become exceedingly complex, requiring a great deal of resources to complete transactions, resources that can not be used for production. In fact, inefficient barter trading was the primary reason that money was invented. With money, more resources can be used for production and fewer are needed for trading. See market.

ASSUMPTIONS, CLASSICAL ECONOMICS Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.
