KEYNESIAN MODEL: A macroeconomic model based on the principles of Keynesian economics that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. This model identifies equilibrium aggregate production and income as the intersection of the aggregate expenditures line and the 45-degree line. The Keynesian model comes in three basic variations designated by the number of macroeconomic sectors included--two-sector, three-sector, and four sector. The Keynesian model is also commonly presented in the form of injections and leakages in addition to the standard aggregate expenditures format. This model is used to analyze several important topics and issues, including multipliers, business cycles, fiscal policy, and monetary policy.

ECONOMIES OF SCALE Declining long-run average cost that occurs as a firm increases all inputs and expands its scale of production. Economies of scale result from increasing returns to scale and are graphically illustrated by a negatively-sloped long-run average cost curve. Economies of scale usually occur for relatively small levels of production and are then overwhelmed by diseconomies of scale for relatively large production levels. Together, economies of scale and diseconomies of scale create a U-shaped long-run average cost curve.
