PERFECT COMPETITION AND SHORT-RUN SUPPLY CURVE: A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.

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.
