ACTUAL INVESTMENT: Investment expenditures that the business sector actual undertakes during a given time period, including both planned investment and any unplanned inventory changes. This is a critical component of Keynesian economics and the analysis of macroeconomic equilibrium, which occurs when actual investment is equal to planned investment. The difference between planned and actual investment is unplanned investment, which is inventory changes caused by a difference between aggregate expenditures and aggregate output. Should actual and planned investment differ, then aggregate expenditures are not equal to aggregate output, and the macroeconomy is not in equilibrium.

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.
