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 PROPENSITY FOR GOVERNMENT PURCHASES The change in government purchases induced by a change in income or production (national income or gross domestic product). The marginal propensity for government purchases (abbreviated MPG) is another term for the slope of the government purchases line and is calculated as the change in government purchases divided by the change in income or production. The MPG plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part of the multiplier process. A related marginal measure is the marginal propensity to consume.
