INJECTION: A non-consumption expenditure on gross domestic product, including investment expenditures, government purchases, and exports. Injections are combined with leakages in the injection-leakage model used to identify equilibrium aggregate output in Keynesian economics. The notion of injection is best viewed through the circular flow, in which investment expenditures, government purchases, and exports are "injected" into the main flow between output, factor payments, national income, and consumption.

SAVING FUNCTION A mathematical relation between saving and income by the household sector. The saving function can be stated as an equation, usually a simple linear equation, or as a diagram designated as the saving line. This function captures the saving-income relation, the flip side of the consumption-income relation that forms one of the key building blocks for Keynesian economics. The two key parameters of the saving function are the intercept term, which indicates autonomous saving, and the slope, which is the marginal propensity to save and indicates induced saving. The injections-leakages model used in Keynesian economics is based on the saving function.
