EFFECTIVE DEMAND: The notion that the actual demand for aggregate output in the macroeconomy is based on the actual income or other existing economic conditions and not on income and conditions existing in equilibrium. The idea of effective demand plays a key role in Keynesian economics and how the macroeconomy can have extended periods of unemployment. Effective demand is in direct contrast to the view underlying classical economics that demand is that existing in equilibrium.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.
