FIXED INPUT: An input in the production of goods and services that does not change in the short run. A fixed input should be compared with a variable input, an input that DOES change in the short run. Fixed and variable inputs are most important for the analysis of short-run production by a firm. The best example of a fixed input is the factory, building, equipment, or other capital used in production. The comparable example of a variable input would then be the labor or workers who work in the factory or operate the equipment. In the short run (such as a day or so) a firm can vary the quantity of labor, but the quantity of capital is fixed.

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 |  Recommended Citation:MARGINAL COST CURVE, AmosWEB GLOSS*arama, http://www.AmosWEB.com, AmosWEB LLC, 2000-2023.

AUTONOMOUS INVESTMENT Business investment expenditures that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in investment. Autonomous investment is best thought of as investment that the business sector undertakes regardless of the state of the economy. It is measured by the intercept term of the investment line. The alternative to autonomous investment is induced investment, which does depend on income.
