Monopoly profits do NOT serve any “socially useful" purpose because: Select one: a. Each of these is a reason why monopoly profits are not socially useful. b. the monopolist's profits are not "competed away". c. the monopolist's profits do not incentivize new investment and a reallocation of resources into the market. d. entry barriers prevent new firms from entering the market to compete with the monopolist.

Q)Economics A market comprises two consumers groups: high-demand types and low-demand types. The high types have demand QH = 10 – P and low types have demand QL = 8 – P. If a monopolist has marginal cost MC = 1 + Q, what is the profit maximising price the monopolist would charge if they are not able to price discriminate? a. 5 b. 6 c. 4 d. 7

What is the profit-maximizing (equilibrium) condition that a monopolist uses to set its quantity of output? Question 8Answer a. Marginal Cost = Marginal Revenue b. Price = Marginal Revenue  c. Price = Average Cost d. Price = Marginal Cost e. Supply = Demand

Figure monopolist, to answer questions a-c. a.  indicate the profit maximizing price and output level and label them P 1 and Q 1. b. Shade in the area that represents the firm's economic profit (or loss). c. If this firm wished to discourage entry by other firms it could produce the output level at which it earns only a zero economic profit. Indicate the price and output level associated with a zero economic profit and label them P 2 and Q 2.

2. A monopolist produces its output in two factories, whose cost curves are given by C1 (q1) = 10q and C2 (q2) demand for the firm's product is given by P = 700 – 5Q where Q is the total quantity sold by the monopolist. (a) On a diagram, illustrate the monopolist's decision about how much to produce at each factory and overall and the price to charge. Briefly explain your diagram. (b) Numerically calculate the monopolist's optimal choices for qı, q2, Q, and P. (c) Suppose that labor costs increase in Factory 1 but not in Factory 2. How should the firm change (i.e. raise, lower, or leave unchanged) each of the values you found in (b)? Your answer should be qualitative, not quantitative. 10q3 where q1 and q2 are the amounts produced at each factory. The diagram might be useful but is not necessary.

Which of the following statements is false? Select one: a. Ceteris paribus, a monopolist charges the same price as a perfect competitor. b. All of the other statements are false. c. The monopolist never takes a loss. d. All monopolies are created by the government.

1.  Using a graph, show a situation in which a monopolist is incurring short-run losses. Explain how this is possible.  2.  Julee has estimated the demand and marginal revenue for her product. They are P = 100 - 2Q (quantity) and MR = 100 - 4Q, respectively. She also experiences constant marginal cost of $16. a. Does Julee have any market power? How can you tell? b. What is Julee’s profit-maximizing quantity? c. What price should Julee charge at that profit-maximizing quantity? 3. Explain a situation in which, when holding costs constant, a monopolist that was earning economic profits in the past can later incur an economic loss.

29. Imagine that you are managing a small firm and thinking about entering the market of a monopolist. The monopolist is currently charging a high price, and you have calculated that you can make a nice profit charging 10% less than the monopolist. Before you go ahead and challenge the monopolist, what possibility should you consider for how the monopolist might react?

1. A monopolist can earn above-normal profit in the long-run. a. True b. False 2. If a monopolist cannot make an above-normal profit, entry by other firms will occur. a. True b. False 3. A monopolist can charge whatever price it wants and, therefore, can reap phenomenal profits.  a. True b. False

a) True or False and Explain: A profit maximizing monopolist has no limit to how high they set the price. b) True of False and explain: When there are economies of scale in production it is possible for a competitive market to sustain the competitive equilibrium. c) When there are economies of scale in production, why is it beneficial to have only one producer?
