RESOURCE QUANTITY, AGGREGATE SUPPLY DETERMINANT: One of three categories of aggregate supply determinants assumed constant when the short-run and long-run aggregate supply curves are constructed, and which shifts both aggregate supply curves when it changes. An increase in a resource quantity causes an increase (rightward shift) of both aggregate supply curves. A decrease in a resource quantity causes a decrease (leftward shift) of both aggregate supply curves. The other two categories of aggregate supply determinants are resource quality and resource price. Specific determinants falling into this general category include population, labor force participation, capital stock, and exploration. Anything affecting the quantity of labor, capital, land, and entrepreneurship is also included.

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.
