VARIABLE INPUT: An input whose quantity can be changed in the time period under consideration. This should be immediately compared and contrasted with fixed input. The most common example of a variable input is labor. A variable input provides the extra inputs that a firm needs to expand short-run production. In contrast, a fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive. This is, by the way, the law of diminishing marginal returns.

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.
