What is the relationship between elasticity and Marginal Revenue = 0 at unit elasticity for a monopolist?

Demand    P=70-Q MR            MR=70-2Q MC            MC=10+Q What is this monopolist profit maximizing rule? How much will he produce? What price does he charge?

The accompanying graph depicts the marginal revenue (MR), demand (D), and marginal cost (MC) curves for a monopoly a. Place point Pi at the profit maximizing price and quantitvy assuming that the monopolist can only charge a single price. 100 95 90 85 80 75 70 65 2 60 b. What are the profits of the firm if it charges a single price? 50 45 Suppose the monopolist able to successfully price discriminate between two groups by charging one group $60 and charging $35 to the other group. c. What are the firm's profits if it charges the two prices as mentioned above? 35 30 25 20 15 10 MR 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95100 Quantity

If a monopoly firm can sell 12 items per day at a price of $150 each, and to increase sales by one (marginal) item per day, the monopolist must lower price to $148, calculate the marginal revenue of the 13th item:

Which price and quantity combination is undesirable for both the monopolist firm and society?   A and E B and F C and G D and H A and H

What is the usual shape of a marginal revenue curve for a monopolist? Why? When a monopolist identifies its profit-maximizing quantity of output, how does it decide what price to charge? Is a monopolist allocatively efficient? Why or why not? ALCOA does not have the monopoly power it once had. How do you suppose their barriers to entry were weakened? For many years, the Justice Department has tried to break up large firms like IBM, Microsoft, and most recently Google, on the grounds that their large market share made them essentially monopolies. In a global market, where U.S. firms compete with firms from other countries, would this policy make the same sense as it might in a purely domestic context? If public utilities are a natural monopoly, what would be the danger in deregulating them? Why does regulatory capture reduce the persuasiveness of the case for regulating industries for the benefit of consumers? In the middle of the twentieth century, major U.S. cities had multiple…

A monopolist serves a market with five potential buyers, each of whom would buy at most one piece of the monopolist's good. Anna would be willing to pay up to £80 for it, Bob up to £90, Chloe up to £100, Dave up to £110 and Elizabeth up to £120. The monopolist's variable cost function is given in below table.

Revenue a) Indicate in the table which price the monopolist would want to charge for each given quantity. b) Find the marginal revenue for each quantity. c) Find the monopolist's profit maximising price under the assumption that he wants to produce anything at all. d) How large can the monopolist's fixed costs be such that he still wants to start producing at 1.

Question 33 Suppose a monopolist faces the demand curve P = 200 – 2Q, has marginal cost curve MC = 2Q, and zero fixed costs. If the monopolist can perfectly price discriminate, which of the following is true?     The monopolist sells 33 units at a profit of 3300.     The monopolist sells 33 units at a profit of 1650.     The monopolist sells 50 units at a profit of 5000.     The monopolist sells 50 units at a profit of 2500.

The demand curve for a monopolist is inelastic. Why?
