FIXED INPUT An input whose quantity cannot be changed in the time period under consideration. The relevant time period is usually termed the short run. The most common example of a fixed input is capital. The alternative to fixed input is variable input. A fixed input, such as capital, provides the "capacity" constraint for the short-run production of a firm. A variable input, such as labor, provides the means of changing short-run production. As larger quantities of a variable input are added to a fixed input, the variable input becomes less productive, which is the law of diminishing marginal returns.
