Q

causes a more than proportionate change in the dependent variable

18
Q

A

a given change in price causes a relatively smaller change in the quantity demanded

19
Q

unit elastic demand

A

20
Q

Determinants of Demand Elasticity (3)

A
  • Ability to postpone a purchase (Yes = elastic, No = inelastic)
  • Substitutes Available (Yes = elastic, No = inelastic)
  • The proportion of income required for the purchase (Yes = elastic, No = inelastic)
