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.
