WEALTH DISTRIBUTION: The manner in which wealth is divided among the members of the economy. A perfectly equal wealth distribution would mean everyone in the country has exactly the same wealth. In reality, wealth is unequally distributed. A few people have a great deal of wealth and most others have less. Any well-functioning economy, that's doing a pretty good job of satisfying consumer wants and needs, will have some degree of inequality in the distribution of wealth. This occurs because some people have done a good job of producing what people want, and thus grow wealthy. However, wealth tends to perpetuate itself, over and above what may be justified by valuable production. Along with wealth comes market control, political power, and the ability to accumulate more wealth at the expense of others.

Aggregate Demand
This lesson introduces aggregate demand, the demand-side of the aggregate market. The aggregate market is the key model used to explain and analyze the workings of the macroeconomy and aggregate demand is a critical half of this model (the other is aggregate supply). Taking a clue from market demand, this lesson examines the nature of aggregate demand, including the relation between the price level and aggregate expenditures, the reason the aggregate demand curve is negatively sloped, and the assorted aggregate demand determinants that cause the aggregate demand curve to shift. - The first unit of this lesson introduces the concept of aggregate demand and how it fits into the study of macroeconomics in terms of the aggregate market and circular flow.
- In the second unit, we example the four aggregate expenditures -- consumption, investment, government purchases, and net exports -- the make up aggregate demand.
- The third unit then examines the aggregate demand curve that captures the aggregate demand relation between the price level and aggregate expenditures, especially the importance of the real-balance, interest-rate, and net-export effects.
- A look at the assorted aggregate demand determinants that shift the aggregate demand curves is the topic of the fourth lesson.
- We end this lesson in the fifth unit with a look how demand-management policies work to stabilize business cycles through aggregate demand.

POINT ELASTICITY The relative responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve.
