Consider two small airlines: Flat Earth Air and Discriminator Air. Each airline has a monopoly on the route it flies. Each faces a market demand curve and marginal cost. The costs of running a flight are about the same no matter how many passengers are on board. Both firms fly the same model of airplane, which seats 200 passengers. So, the marginal cost of adding one passenger - the extra weight and the cost of a can of soda or two - is very small, almost negligible. Therefore, let's assume that each airlines marginal cost is constant and equal to the average total cost. What happens if one of the airlines price-discriminates but the other one does not? Explain, using diagrams: one for Flat Earth Air and one for Discriminator Air. All diagrams must be labeled appropriately and identify any profit, consumer surplus, and/or dead-weight loss.

Step 1
The demand curve represents the quantity of tickets that customers are willing to purchase at different prices. Since each airline has a monopoly on its route, the demand curve for each airline will be downward sloping. Show more…

Draw a diagram, including demand, marginal revenue, marginal cost, and any other curves necessary, to illustrate each of the following two situations for a monopolistic competitor: a. The firm is suffering a loss, and it should shut down in the short run. b. The firm is suffering a loss, but it should stay open in the short run.
Suppose the cost of flying a 200-seat plane for an airline is $100,000 and there are 10 empty seats on a flight. If the marginal cost of flying a passenger is $200 and a standby passenger is willing to pay $300, the airline should...a. sell the ticket because the marginal benefit exceeds the marginal cost. b. sell the ticket because the marginal benefit exceeds the average cost. c. not sell the ticket because the marginal benefit is less than the marginal cost. d. not sell the ticket because the marginal benefit is less than the average cost.

Consider the relationship between monopoly pricing and price elasticity of demand. a. Explain why a monopolist will never produce a quantity at which the demand curve is inelastic. ($Hint$: If demand is inelastic and the firm raises its price, what happens to total revenue and total costs?) b. Draw a diagram for a monopolist, precisely labeling the portion of the demand curve that is inelastic. ($Hint$: The answer is related to the marginal-revenue curve.) c. On your diagram, show the quantity and price that maximize total revenue.
