DOUBLE COINCIDENCE OF WANTS: The requirements of a barter exchange that each trader has want the other wants and wants what the other has. Because everyone doesn't necessarily want everything, the lack of double coincidence of wants is a major obstacle in barter exchanges, especially for complex, modern economies. While double coincidence of wants is also essential for exchanges involving money, it's such an inherent trait of money we don't think twice about it.

INJECTIONS-LEAKAGES MODEL A macroeconomic model that balances non-consumption expenditures on production (injections) and non-consumption uses of income (leakages) that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. The injections-leakages model is based on the principles of Keynesian economics and provides an alternative to the standard aggregate expenditures (Keynesian cross) analysis. The three injections included in the model are investment expenditures, government purchases, and exports. The three leakages included in the model are saving, taxes, and imports. Three variations are the two-sector injections-leakages model (or saving-investment model), three-sector injections-leakages model, and four-sector injections-leakages model.
