When a firm can distinguish consumers with a high versus low willingness to payB. When a firm offers a menu of alternatives, designed so that different customers will makedifferent choices based on their willingness to payC. A monopolist knows perfectly the customer's willingness to pay for each unit its sells and cancharge a different price for each unitD. B and C12. A movie monopolist sells to students and adults.

Kate and Alice are small-town ready-mix concrete duopolists. The market demand functioniswhere P is the price of a cubic yard of concrete and Qd is the number ofcubic yards demanded per year.

They collude without communicating, sustaining a price above the noncooperative price thatwould arise in a single competitive interactionC. They communicate to reach an agreement about the prices they will chargeD. They communicate what type of good they will produceSHORT ANSWER QUESTIONS / PROBLEMS1. (10 points) Suppose the wiz-pop market is in long-run equilibrium. Suddenly, fixed costsdecrease, although variable costs remain unchanged. Discuss the short-run and long-run changesin market equilibrium.2. (10 points) After Apple introduced its new iPhone, the price of standard cell phones rose. Aconsumer advocacy group that has long claimed that standard cell phone producers are colludinglike a monopolist asserts that this is further evidence of that fact. Youve noticed that theelasticity of demand for standard cell phones increased after Apples entry. Does this shed anylight on the groups claim?3. (20 pts.) Suppose Always There Wireless serves 100 high-high demand wireless consumers,each of whose monthly demand curve for minutes of wireless service isand300 low-demand consumers, each of whose monthly demand curve for minutes of wireless is, where P is the per-minute price in dollars. Its marginal cost is \$0.25 perminute. Suppose Always There Wireless charges \$0.25 per minute.a. How many minutes will high-demand consumers purchase?b. How many minutes will low-demand consumers purchase?c. How much can Always There Wireless charge as a fixed fee without losing the low-demandconsumers?d. What are the profits from sales to each of the low-demand consumers?4. (20 pts.) a. Define the Bertrand model and its assumptions. Explain why the model predictsthe perfectly competitive outcome despite the number of sellers. Discuss the limitations of themodel.b. Compare and contrast the Bertrand and Cournot models of oligopoly. Your discussion shouldinclude assumptions made, goals of the firms and the resulting outcomes.
