Question

Using regression analysis on data from a field experiment, the demand curve for a product is estimated to be QXd = 1,200 − 3PX − 0.1PZ where Pz = $300.
 

a. What is the own price elasticity of demand when Px = $140? Is demand elastic or inelastic at this price? What would happen to the firm’s revenue if it decided to charge a price below $140?

Instruction: Enter your response rounded to two decimal places.

Own price elasticity: 

 

Demand is:           .

 

If the firm prices below $140, revenue will:              .

 

b. What is the own price elasticity of demand when Px = $240? Is demand elastic or inelastic at this price? What would happen to the firm’s revenue if it decided to charge a price above $240?

Instruction: Enter your response rounded to one decimal place.

Own price elasticity: 

 

Demand is:           .

 

If the firm prices above $240, revenue will:              .

 

c. What is the cross-price elasticity of demand between good X and good Z when Px = $140? Are goods X and Z substitutes or complements?

Instruction: Enter your response rounded to two decimal places.

Cross-price elasticity: 

 

Goods X and Z are:           .
