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).

PERSONAL INCOME

The total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time, usually one year. Personal income (PI) is one of three measures of income reported in the National Income and Product Accounts maintained by the Bureau of Economic Analysis. The other two are national income (NI) and disposable income (DI). Two related measures of production are gross domestic product (GDP) and net domestic product (NDP). The primary use of personal income is to measure the income actually paid out to the household sector. After adjusting for income taxes, personal income forms the basis for consumption expenditures on gross domestic product.
