What to Focus On

  • Elasticity of demand measures responsiveness of demand to price change.
  • It is also called price elasticity of demand.
  • Percentage change is used because it is independent of units.

  • Ed = percentage change in demand / percentage change in price.
  • Ed = ΔQ / ΔP × P / Q.
  • Percentage changes are independent of units.

  • There are five degrees of price elasticity of demand.
  • Perfectly inelastic demand: Ed = 0.
  • Inelastic demand: Ed < 1.

Common Mistakes to Avoid

Price elasticity of demand means the change in price caused by a change in demand.

Elastic demand means the same thing as inelastic demand because both involve a change in demand.

The sign of price elasticity is more important than the size of the elasticity.
