Here's the solution to question 2 from the image. a) i) Co-efficient of income Step 1: Calculate the percentage change in quantity demanded. The quantity demanded changed from 50 to 40. Percentage change in quantity demanded = New quantity - Old quantityOld quantity × 100\% = (40 - 50)/(50) × 100\% = (-10)/(50) × 100\% = -0.2 × 100\% = -20\% Step 2: Calculate the percentage change in income. The income changed from N120,000 to N200,000. Percentage change in income = New income - Old incomeOld income × 100\% = (200,000 - 120,000)/(120,000) × 100\% = (80,000)/(120,000) × 100\% = (2)/(3) × 100\% ≈ 66.67\% Step 3: Calculate the income elasticity of demand (co-efficient of income). Income Elasticity of Demand = Percentage change in quantity demandedPercentage change in income = (-20\%)/(66.67\%) ≈ -0.30 The co-efficient of income is -0.30. a) ii) What type of goods is garri to Mr. Adebowale? Since the income elasticity of demand is negative (-0.30), garri is an inferior good to Mr. Adebowale. This means that as his income increases, his demand for garri decreases. b) Briefly explain four factors affecting elasticity of supply. • Availability of inputs: If inputs (raw materials, labor, capital) are readily available and can be easily sourced, supply will be more elastic. If inputs are scarce or difficult to obtain, supply will be inelastic. • Time horizon: In the short run, supply tends to be more inelastic because producers have limited ability to change production capacity. In the long run, producers have more time to adjust their production processes and capacity, making supply more elastic. • Storage capacity: If a good can be easily stored without significant cost or spoilage, producers can hold inventory and adjust supply more flexibly, leading to more elastic supply. Perishable goods or goods with high storage costs tend to have inelastic supply. • Mobility of factors of production: If factors of production (like labor and capital) can be easily moved from one industry to another, producers can quickly respond to price changes by reallocating resources, making supply more elastic. If factors are specialized and immobile, supply will be inelastic. Send me the next one 📸
