EXCESS SUPPLY: A disequilibrium condition in a competitive market in which the quantity supplied is greater than the quantity demanded, hence there's "extra" supply. Pointy-headed economists generally use the more technical term surplus rather than excess supply. The reason, of course, is that surplus has two syllables and excess supply has four. The time saved in pronouncing two syllables rather than four is a definite efficiency plus for the entire economy.

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.
