Consumer Equilibrium is achieved when MUx = Px
Elasticity of Demand • Elasticity of demand is a measure of sensitivity of quantity demand to a change in any one of the determinants of demand. • There are THREE types of elasticity of demand: 1. Price elasticity of demand 2. Income elasticity of demand 3. Cross elasticity of demand
Elasticity of Demand 1. Price elasticity of demand:
Elasticity of Demand 1. Price elasticity of demand: Measuring price elasticity of demand: Point formula: PED: (ΔQD/ΔP)x(P/QD) Arc Elasticity formula: PED: (ΔQD/ΔP)x(P 1+P 2/QD 1+QD 2)
