ECONOMIES OF SCALE: Declining long-run average cost that occurs as a firm increases all inputs and expands its scale of production. This is graphically illustrated by a negatively-sloped long-run average cost curve and typically occurs for relatively small levels of production. Economies of scale are then overwhelmed by diseconomies of scale for relatively large production levels. Together, economies of scale and diseconomies of scale cause the long-run average cost curve to be U-shaped.

MARGINAL PROPENSITY TO IMPORT

The change in imports purchased from the foreign induced by a change in income or production (national income or gross domestic product). The marginal propensity to import (abbreviated MPM) is another term for the slope of the imports line and is calculated as the change in imports divided by the change in income or production. The MPM 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.
