Lesson 12: Elasticity and Demand | Unit 2: The Continuum

- A graphical look at three alternatives:
- Perfectly Elastic: Perfectly elastic demand results when infinitesimally small changes in price lead to infinitely large changes in quantity.
- Perfectly Inelastic: Perfectly inelastic demand results the quantity demanded does not change regardless of any change in price.
- Unit Elastic: Unit elastic demand results when the perfect change in quantity is EXACTLY the same as the percentage change in price.
- The most noted feature of this demand curve is that it is a curve and not a straight line -- the slope changes along the curve.

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.
