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.

INJECTIONS LINE A graphical representation of the relation between the level of aggregate production and one or more injections. The three injections (non-consumption expenditures on aggregate production) are investment expenditures, government purchases and exports. The injections line sequentially adds, or layers, each of these three expenditures depending on the number of sectors used in the analysis (two, three, or four). The slope of the injections line depends on which if any of the expenditures are induced by aggregate production. The injections line is combined with the leakages line (containing saving, taxes, and imports) in the Keynesian injections-leakages model.
