3. The Elasticity of Demand
Measure of the responsiveness of quantity demanded or quantity supplied
Percentage change in quantity demanded (∆Qd/Qd)
Percentage change in quantity supplied (∆Qs/Qs)
To a change in one of its determinants
Demand-side
(own) price <-> demand elasticity (∆Qx/Qx)/ (∆Px/Px )
Price of substitute/complement <-> cross-price (∆Qx/Qx)/(∆Py/Py )
Income <-> income elasticity ((∆Qx/Qx)/ (∆I/I )
