AGGREGATE DEMAND DETERMINANT: A ceteris paribus factor that affects aggregate demand, but which is assumed constant when the aggregate demand curve is constructed. Changes in any of the aggregate demand determinants cause the aggregate demand curve to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate demand curve to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate demand curve. If any determinant affects aggregate demand it MUST affect one of these four expenditures.

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). See also | marginal cost | curve | quantity | law of diminishing marginal returns | technology | resource prices | increasing marginal returns | decreasing marginal returns | U-shaped cost curves | average total cost curve | average variable cost curve | average fixed cost curve | total cost curve |

NORMATIVE ECONOMICS The branch of economics that seeks to recommend the way the economy should operate. It is the policy side of economics that is based on individual preferences and cannot be proven either right or wrong. A normative economic statement cannot be refuted by looking at the real world--that is, by testing hypotheses.
