Topics in Elasticity of Demand

1

Meaning and Core Idea

  • Elasticity of demand tells the amount of change in quantity demanded of a commodity in response to a change in its price.
  • It shows the responsiveness or sensitivity of demand to price change.
  • A larger reaction means higher elasticity.
2

Percentage Method and Formula Use

  • The percentage method measures price elasticity of demand by taking the ratio of percentage change in demand to percentage change in price.
  • The formula can be written in expanded form using change in quantity and change in price.
  • The simplified formula is obtained after canceling 100 in both numerator and denominator.
3

Degrees or Kinds of Price Elasticity of Demand

  • There are five kinds or degrees of price elasticity of demand.
  • Perfectly inelastic demand means quantity demanded does not change at all when price changes.
  • Inelastic demand means demand changes less than price.
4

Demand Curves and Total Expenditure

  • Perfectly inelastic demand is shown by a vertical demand curve.
  • Inelastic demand is shown by a steep demand curve.
  • Unit elastic demand is shown by a rectangular hyperbola.
