Essay Questions 84. A monopolist's demand curve is given by DM and its average cost curve is AC as shown here. Suppose a potential entrant can produce at the same cost as the monopolist.

a. What level of output does the monopolist have to produce in order for the entrant to face the residual demand curve, DR? b. How much profit will the monopolist earn if it commits to the output that generates the residual demand curve, DR? c. Is the level of output that generates the residual demand curve, DR, enough for the monopolist to deter entry?

Answer: a. 25 units b. Note that P = $175, AC = $75, and Q = 25, so profits are ($175 − $75)(25) = $2,500. c. No; even if the monopolist could credibly commit to producing 25 units, it is profitable for the entrant to enter since P > AC for some quantities.

Player A

Player B Strategy Top Bottom

Left $100, $200 $500, −$50

Right −$10, $100 −$100, −$100

a. What is player B's best strategy in a simultaneous-move play of this game? b. What is player A's best strategy in a simultaneous-move play of this game? c. What are player A and B's equilibrium payoff in a simultaneous-move play of this game? d. Use an extensive-form representation to show that player B can earn higher payoffs by exercising a first-mover advantage. (Note: Player B's payoffs will appear first in this extensive-form game since it is the first mover.) e. List two things player B must do in order to be able to achieve these higher payoffs. Answer: a. "Left" is a dominant strategy for Player B. b. "Bottom," since player A should anticipate that B will play its dominant strategy. c. ($500, −$50) d. See the extensive-form game shown in the figure below. Notice that if player B moves first, its best response is "Right." To see this, notice that if B plays "Left," A will play "Bottom" since $500 is better than $100. If B plays "Right," A's best response is "Top" since −$10 is better than −$100. Thus, player B earns a payoff of $100 by moving first and playing "Right," compared to the payoff of −$50 that is achieved if it does not exercise this first-mover advantage. Top

87. SunCenter is the only firm in its industry. Currently, SunCenter charges $75 per unit, a price well in excess of its marginal cost of $5 per unit, and earns $70 million per year in profit. According to a trusted source, the manager of SunCenter learned that a new firm is contemplating entering the market. This would reduce its profit to $40 million per year. If SunCenter expanded its output and lowered its price to $50, the entrant would find it unprofitable to enter the market, and SunCenter would earn profits of $50 million per year for the indefinite future. a. What pricing strategy is the manager of SunCenter considering? b. If SunCenter was able to credibly commit to maintain a price of $50, would it be a profitable strategy? Explain. Answer: a. Limit pricing. It is not predatory pricing since there is currently no firm in the market, and the proposed price is above its marginal cost. b. Assuming the firm can credibly commit to maintain the price of $50, limit pricing is profitable if or in this case,

. Simplifying, we see that limit pricing is

profitable if . Solving for i, it follows that limit pricing is profitable if i < 0.5. That is, so long as the interest rate is less than 50 percent, limit pricing is a profitable strategy.

88. Sanford Inc. currently competes in a duopoly. The market price is $10, and Sanford's annual profit is $10 million. If Sanford were the only firm in the market, it could charge the monopoly price of $25 per unit and earn $35 million annually for an indefinite period of time. By charging $5 per unit for one year, Sanford could drive its rival out of the market and maintain a monopoly position indefinitely. However, this strategy will result in a $20 million loss since its marginal cost is $8 per unit. a. What pricing strategy is the manager considering? b. Ignoring legal considerations, is this pricing strategy profitable? Assume the interest rate is 5 percent and, for simplicity, that any current period profits or losses occur immediately (at the beginning of the year). Answer: a. Predatory pricing b. If Sanford does not engage in predatory pricing, the present value of its earnings (including current earnings of $10 million) is

= (21)($10) =$210 million If Sanford uses predatory pricing, the present value of its current and future profits is

= −$20 + $700 =$680 million In this case, Sanford earns more by predatory pricing. Learning Objective: 13-02 Topic: Predatory Pricing to Lessen Competition Blooms: Apply AACSB: Analytical Thinking Difficulty: 02 Medium

89. As a newly hired stock analyst, your first job is determining the value of a company that sells a service that has extremely strong network effects. Essentially, this firm sells a two-way network that links users and currently comprises 50,000 nodes. Each connection service within the network has a value of $10. Estimate the total value of the firm. Answer: With 50,000 nodes, the total number of potential connection services is 2,499,950,000, computed as 50,000(49,999). Since each of these connection services is valued at $10, the total value of the network is $24,999,500,000, or almost $25 billion.

90. You are the owner of a new network that is superior to an existing two-way network. The network you aim to replace currently has 50 users, each of whom is willing to pay an average of $75,000 for each connection service within the current network. You are confident that each user values connection services within your new two-way network at an average of $100,000 per connection service. a. What is the maximum price the existing network can charge each user for its services? b. Devise a pricing strategy that will permit your firm to overcome the first-mover advantage enjoyed by the existing network. Answer: a. The existing network provides 50(49) = 2,450 potential connection services. Since each consumer values connection services at an average of $75,000 per connection, the total value to each consumer of the existing network is $183,750,000. Thus, the maximum amount a user would pay to use the existing network is $183,750,000. b. Notice that the maximum amount each user will pay for access to the new network is $245,000,000 (since 2,450 × $100,000 = $245,000,000). However, a user will only pay this amount if all 50 users subscribe to the new network! To get all users to switch, the owner of the new network should consider a penetration pricing strategy. Examples include initially giving services away for free or even paying a small amount to induce users to switch to the new network. Once all users switch, the price can be increased to $245,000,000 per user.
