For the next two problems, it may help to refer the graphs that we drew in the class notes. Suppose a market is monopolized. Suppose the demand function is P = 120 â 2Q. (This is an inverse demand function, meaning we have solved for P instead of Q). The resulting Marginal Revenue function is MR = 120 â 4Q. If the Marginal Cost function for this monopoly is MC = 2Q, find the optimal quantity Q* that this profit-maximizing monopoly should produce.
A) Q = 5
B) Q = 8
C) Q = 10
D) Q = 15
E) Q = 20
F) Q = 60
G) Q = 120
12.
Using your answer from the previous question, find the price the monopolist will charge.

B) P = $40
C) P = $60
D) P = $80
E) P = $100
F) P = $120
A single-price monopolist is maximizing profit at an output rate of 1,500 units per month. At this output rate, the price that its customers are willing and able to pay is $12 per unit, average total cost is $8 per unit, and marginal cost is $7 per unit. It may be concluded that at this monthly output rate, marginal revenue is
A) $7 per unit, and the monopolist earns economic profits of $6,000 per month
B) $7 per unit, and the monopolist earns economic profits of $7,500 per month
C) $8 per unit, and the monopolist earns economic losses of $6,000 per month
D) $8 per unit, and the monopolist earns economic profits of $7,500 per month
E) $12 per unit, and the monopolist earns economic profits of $6,000 per month
F) $12 per unit, and the monopolist earns economic profits of $7,500 per month
16.
Suppose a monopoly is going to engage in a two-part-tariff pricing strategy. The monopoly wants to charge an entry fee (E) which will cover the fixed costs of production. Suppose also that the monopolist is going to set a price so that the market will be allocatively efficient. Suppose that the market has N = 200 consumers, fixed costs are FC = $4,000, and marginal costs are constant at MC = $8. What entry fee (E) and price (P) should this monopolist charge in its two-part-tariff pricing strategy? Hint: Look in your notes to find out what price needs to be set such that the market will be allocatively efficient.
A) E = $4000, P = $8
B) E = $4000, P = $25
C) E = $20, P = $8
D) E = $20, P = $25
