PIE CHART: A circular graph divided into wedges that is commonly used to present the division of a total among parts. The circular "pie" represents the total value and each slice represents the portion distributed to each category. Pie charts are a handy way to present information, but are not well suited for more involved economic analysis.

Some Definitions
|
|
|
- The working, measurement based definition goes something like this:
- Elasticity is the percentage change of one variable relative to the percentage change in another variable.
- When applied to market analysis, specific elasticity definitions work for both demand and supply:
- The price elasticity of demand is the percentage change in quantity demanded resulting from a percentage change in demand price.
- The price elasticity of supply is the percentage change in quantity supplied resulting from a percentage change in supply price.

AGGREGATE DEMAND SHIFTS Changes in the aggregate demand determinants cause the aggregate demand curve to shift. The mechanism is comparable to that for market demand determinants and market demand. There are two alternatives--an increase in aggregate demand and a decrease in aggregate demand. An increase in spending by any of the four sectors--household, business, government, and foreign--shifts the aggregate demand curve to right. A decrease in spending by these four sectors shifts the aggregate demand curve to left.
