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.

Demand
This lesson on demand offers a little insight into the purchases of a wide range of goods. In fact, this demand topic is does more than offer insight into buying behavior. It's also one half of the market analysis -- the other half being supply. And market analysis is one of the most widely used tools in the study of economics. Economists explain a lot of economic phenomenon using markets. But to use markets, we need demand. And that brings us back to this lesson. - In the first unit of this lesson we examine the basic concept of demand. While you've likely come across the term demand before, we'll see the specific way the term is used in economics.
- The second unit then takes a look at the law of demand, which is one of the most important and most fundamental economic principles that we'll encounter.
- As we more on to the third unit, our attention turns to the demand curve, which is the graphical embodiment of the demand concept.
- In the fourth unit, we examine how the five basic demand determinants cause the demand curve to shift from one location to another.
- And finally in the fifth unit, we make a connection between demand and the fundamental problem of scarcity.

FALLACY OF COMPOSITION The logical fallacy of arguing that what is true for the parts is also true for the whole. In the study of economics, this takes the form of assuming that what works for parts of the economy, such as households or businesses, also works for the aggregate, or macroeconomy. The contrasting fallacy is the fallacy of division.
