Answer:
Buy 7% less houses
Explanation:
Income elasticity of demand measures the responsiveness of quantity demanded to changes in income
Income elasticity of demand = percentage change in quantity demanded/ percentage change in income
1.40 = percentage change in quantity demanded/ 5%
Percentage change in quantity demanded = 1.4 × 5% = 7%
Because the coefficient of elasticity is greater than one, it means demand is income elastic. This means quantity demanded is responsive to changes in income. A fall in income would reduce the quantity demanded.
