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.

THREE-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes the three domestic sectors, the household sector, the business sector, and the government sector. This Keynesian model variation adds the government sector (or public sector) to the household and business sectors that make up the two-sector model. This model enables an analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the C + I + G line and the 45-degree line. Two related models are the two-sector Keynesian model and the four-sector Keynesian model.

The Depths Of DEPRESSIONIn the discussion of recession we see that one of the problems confronting both pedestrians and the economy is stepping in an occasional pothole. These potholes are usually small and do little damage. Every now and then, however, our economy falls face first into one humdinger of pothole that's big enough to swallow the better part of a marching band. Rather than a mere recessionary pothole, these are best thought of as depressionary canyons. The Great Depression of the 1930s was the most memorable depressionary canyon on record for the good old U. S. of A. The question we need to ponder over the next few pages is: Are there any more depressionary canyons like the 1930s lurking along the economic pavement?

[What's This?]
Today, you are likely to spend a great deal of time flipping through the yellow pages trying to buy either a remote controlled World War I bi-plane or a wall poster commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for malfunctioning pocket calculators.
