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

They communicate what type of good they will produceSHORT ANSWER QUESTIONS / PROBLEMS(10 points) Suppose the wiz-pop market is in long-run equilibrium. Suddenly, fixed costs decrease, although variable costs remain unchanged. Discuss the short-run and long-run changes in market equilibrium.(10 points) After Apple introduced its new iPhone, the price of standard cell phones rose. A consumer advocacy group that has long claimed that standard cell phone producers are colluding like a monopolist asserts that this is further evidence of that fact. You?ve noticed that the elasticity of demand for standard cell phones increased after Apple?s entry. Does this shed any light on the group?s claim?(20 pts.) Suppose Always There Wireless serves 100 high-high demand wireless consumers,each of whose monthly demand curve for minutes of wireless service isand 300 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 per minute. Suppose Always There Wireless charges $0.25 per minute.How many minutes will high-demand consumers purchase?How many minutes will low-demand consumers purchase?How much can Always There Wireless charge as a fixed fee without losing the low-demand consumers?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 predicts the perfectly competitive outcome despite the number of sellers. Discuss the limitations of the model.b. Compare and contrast the Bertrand and Cournot models of oligopoly. Your discussion should include assumptions made, goals of the firms and the resulting outcomes.
