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.

The natural selection of business firms is an adaptation of the biological process of natural selection, in which biological entities best suited to the natural environment are the ones that survive. The concept of economic natural selection is aimed primarily at the profit-maximization assumption. Although firms might not seek to maximize profit on a day-to-day basis, those that come closest (intentionally or unintentionally) are the ones that remain in business.
