Step 1: Calculate the elasticity of supply between A and B. The midpoint formula for price elasticity of supply (PES) is: PES = (Q_2 - Q_1)/((Q_2 + Q_1)/2)(P_2 - P_1)/((P_2 + P_1)/2) For points A (P_1=5, Q_1=10) and B (P_2=10, Q_2=25): Percentage change in quantity supplied: (25 - 10)/((25 + 10)/2) = (15)/(35/2) = (15)/(17.5) Percentage change in price: (10 - 5)/((10 + 5)/2) = (5)/(15/2) = (5)/(7.5) Now, calculate PES: PES_AB = (15/17.5)/(5/7.5) = (15)/(17.5) × (7.5)/(5) = (112.5)/(87.5) = (9)/(7) ≈ 1.286 The elasticity of supply between A and B is (9)/(7) or approximately 1.286. Step 2: Calculate the elasticity of supply between D and E. For points D (P_1=20, Q_1=60) and E (P_2=25, Q_2=75): Percentage change in quantity supplied: (75 - 60)/((75 + 60)/2) = (15)/(135/2) = (15)/(67.5) Percentage change in price: (25 - 20)/((25 + 20)/2) = (5)/(45/2) = (5)/(22.5) Now, calculate PES: PES_DE = (15/67.5)/(5/22.5) = (15)/(67.5) × (22.5)/(5) = (337.5)/(337.5) = 1 The elasticity of supply between D and E is 1. Step 3: State the nature of elasticity in (a)(i). For (a)(i), the elasticity of supply is 9/7 ≈ 1.286. Since this value is greater than 1, the supply is elastic. Step 4: Briefly explain any four types of elasticity of demand. • Price Elasticity of Demand (PED) measures how much the quantity demanded of a good responds to a change in its price. • Income Elasticity of Demand (YED) measures how much the quantity demanded of a good responds to a change in consumers' income. • Cross-Price Elasticity of Demand (XED) measures how much the quantity demanded of one good responds to a change in the price of another good. • Advertising Elasticity of Demand (AED) measures how much the quantity demanded of a good responds to a change in advertising expenditure.
