MARGINAL COST CURVE: A curve that graphically represents the relation between marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables, like technology and resource prices, constant. The marginal cost curve is U-shaped. Marginal cost is relatively high at small quantities of output, then as production increases, declines, reaches a minimum value, then rises. This shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns (and the law of diminishing marginal returns).

FOUR-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes all four macroeconomic sectors, the household sector, the business sector, the government sector, and the foreign sector. This Keynesian model variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model. This model provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the C + I + G + (X - M) line and the 45-degree line. Two related variations are the two-sector Keynesian model and the three-sector Keynesian model.
