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.

MARGINAL PROPENSITY TO INVEST

The change in business investment expenditures induced by a change in income or production (national income or gross domestic product). The marginal propensity to invest (abbreviated MPI) is another term for the slope of the investment line and is calculated as the change in investment divided by the change in income or production. The MPI plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.
