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.

THREE-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes the three domestic sectors, the household sector, the business sector, and the government sector. This Keynesian model variation adds the government sector (or public sector) to the household and business sectors that make up the two-sector model. This model enables an analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the C + I + G line and the 45-degree line. Two related models are the two-sector Keynesian model and the four-sector Keynesian model.
