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.

SAY'S LAW A principle of classical economics developed the French economist Jean-Baptiste Say that is commonly summarized as "supply creates its own demand." This law, also referred to as Say's "theory of markets" or "law of markets," indicates that the act of producing aggregate output generates a sufficient amount of aggregate income to purchase all of the output produced. This principle indicated that excess production or insufficient demand for production was unlikely to occur, at least for any extended period. When combined with flexible prices and saving-investment equality, Say's law further implied that an economy would achieve and maintain full employment of resources. This law was singled out by John Maynard Keynes in his critique of classical economics, but remains relevant in current macroeconomic analysis, reflected in the circular flow model.
