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.

ELASTICITY The relative response of one variable to changes in another variable. Elasticity is commonly used in the study of market exchanges to identify the relative response of quantity (demanded and supplied) to changes in price. The phrase "relative response" is best interpreted as the percentage change, such as, the percentage change in quantity measured against the percentage change in price. The most common notions of elasticity are the price elasticity of demand and the price elasticity of supply. Other notable economic elasticities are the income elasticity of demand and the cross elasticity of demand.
