VARIABLE COST: In general, cost that changes with changes in the quantity of output produced. More specifically, variable cost is combined with the adjectives "total" and "average" to indicate the overall level of variable cost or the per unit variable cost. Variable cost depends on the amount of produced. If there is no production, then there is no variable cost.

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.
