Using the midpoint method, calculate the price elasticity of demand of Good X using the following information: When the price of good X is $50, the quantity demanded of good X is 400 units. When the price of good X rises to $60, the quantity demanded of good X falls to 300 units.
The price elasticity of demand for good X = 0.64.
The price elasticity of demand for good X = 1.57.
Ans.
Midpoint method to calculate price elasticity of demand is :
ed = [(Q2 - Q1) / (Q1 + Q2) /2] / [ (P2 - P1) / (P2 + P1) /2 ]
ed = [300 - 400 / (300+400) /2 ] / [ 60 - 50 / (60+50) / 2 ]
ed = [ -100 / (700) /2 ] / [ 10 / (110) /2]
ed = [ -100 / 350 ] / [ 10 / 55 ]
ed = [-100 / 350 ] * [55 / 10 ]
ed = -55 / 35
ed = 1.57
Thus, price elasticity of demand for good X = 1.57

Using the midpoint method, the price elasticity of demand for a good is computed to be approximately 1.5, the price increases by 3.5%, and Q1=25,294. What is Q2?
Suppose that the per-unit price of good X is fixed at $5. When the price of good Y equals $8, the quantity demanded of good X is 12. When the price of good Y rises to $10, the quantity demanded of good X falls to 10. The cross-price elasticity of demand for good X with respect to the price of good Y between these two points, calculated using the midpoint formula, equals O 0.82 O -0.82 O 1.22 0 -1.22

If the income elasticity of demand for a good is negative, then the good must be an inferior good. True False Question 2 The law of demand states that, other things equal, when the price of a good rises, the quantity demanded of the good falls, and when the price falls, the quantity demanded rises. True False Question 3 A price ceiling set above the equilibrium price is not binding. True False Question 4 The cross-price elasticity of garlic salt...
