6. MUx = ΔTU/ ΔQx Consumer Equilibrium is achieved when MUx = Px

9. 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

10. Elasticity of Demand 1.Price elasticity of demand:

11. 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 )
