VARIABLE INPUT: An input whose quantity can be changed in the time period under consideration. This should be immediately compared and contrasted with fixed input. The most common example of a variable input is labor. A variable input provides the extra inputs that a firm needs to expand short-run production. In contrast, a fixed input, like capital, provides the capacity constraint in production. As larger quantities of a variable input, like labor, are added to a fixed input like capital, the variable input becomes less productive. This is, by the way, the law of diminishing marginal returns.

RESOURCE QUALITY, AGGREGATE SUPPLY DETERMINANT One of three categories of aggregate supply determinants assumed constant when the short-run or long-run aggregate supply curves are constructed, and which shifts both aggregate supply curves when it changes. An increase in a resource quality causes an increase (rightward shift) of both aggregate supply curves. A decrease in a resource quality causes a decrease (leftward shift) of both aggregate supply curves. The other two categories of aggregate supply determinants are resource quantity and resource price. Specific determinants falling into this general category include education and technology. Anything affecting the quality of labor, capital, land, and entrepreneurship is also included.
