Question 10 D Assume that the price elasticity of demand for good X is constant and equal to -0,5 and the price elasticity of demand for good Y is constant and equal to -2, Assume that goods X and Y have identical upward- sloping elastic supply curves. If a per-unit excise tax of the same amount is levied on good X and on good Y, which of the following would be true? The percentage decrease in the quantity of good X demanded would be greater than the percentage decrease in the quantity of good Y demanded. The tax share paid by consumers of good X would be relatively higher than that paid by consumers of good Y The tax share paid by consumers of good Y would be relatively higher than that paid by consumers of good X. The tax share paid by sellers of good Y would be relatively lower than that paid by sellers of good X. The tax share paid by sellers of goods X and Y would be the same' 0
