ELASTICITY General Case Note: Unit Free (Unlike Slope = dZ/dW)
ELASTICITY • Examples: Own Price Elasticity of Demand Income Elasticity of Demand Cross Price Elasticity of Demand
OWN PRICE ELASTICITY where is the slope of the demand curve
OWN PRICE ELASTICITY eii=f(substitutability, time, proportion on income spent on the good,…) Cobb – Douglas e = -1 (Show) Perfect Substitutes e = ? Perfect Complements e = ?
INCOME ELASTICITY OF DEMAND Income Elasticity of demand i> 0 Normal good i< 0 Inferior good
CROSS PRICE ELASTICITY OF DEMAND Cross Price Elasticity of demand eij > 0 Substitutes eij < 0 Complements
