PERFECT COMPETITION, LONG-RUN PRODUCTION ANALYSIS: In the long run, a perfectly competitive firm adjusts plant size, or the quantity of capital, to maximize long-run profit.

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.
