MARKET FAILURES: Conditions in which a market does not efficiently allocate resources to achieve the greatest possible consumer satisfaction. The four main market failures are--(1) public good, (2) market control, (3) externality, and (4) imperfect information. In each case, a market acting without any government imposed direction, does not direct an efficient amount of our resources into the production, distribution, or consumption of the good.

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.
