Suppose that an industry is characterized as follows:
C = 100 + 2q2 each firm’s total cost function
MC = 4q firm’s marginal cost function
P = 90 – 2Q industry demand curve
MR = 90 – 4Q industry marginal revenue curve
If there is only one firm in the industry, find the monopoly level of profit.
a. R550
b. R406.25

Question 5
Complete

b. treat each other’s price as fixed when making an output decision.
c. treat each other’s quantity as fixed when making an output decision.
d. will pick the strategy most damaging to each other.
Question 6
Complete

What do the Cournot and Bertrand models have in common?
a. Both are oligopoly models in which firms produce a good that the consumer cannot easily substitute.
b. The two models have nothing in common.
c. None of the options are correct
d. In both models, each firm takes some aspect of its rivals behavior (either quantity or price) as fixed when making its own decision.
, Question 7
Complete
M ark 3.00 out of 3.00
A firm faces the following average revenue (demand) curve:
P = 120 – 0.02Q
where Q is weekly production and P is price, measured in cents per unit. The firm’s cost function is given by C = 60Q + 25,000. Assume
that the firm maximizes profits.
What is the level of production?
a. 750
b. 1500
c. 6000
d. 3000

reservation price of the consumer is
a. 50
b. 130
c. 30
d. 80
Question 9
Complete
M ark 2.00 out of 2.00
Which of the following statements about a monopolistic competitor is FALSE?
a. The demand curve of a monopolistic competitor and that of its competitors may all have different positions.
b. A monopolistic competitor will produce at an output level where its MR and SMC curves intersect, given that it would make either
a profit or a loss, which is less than its total fixed cost.
c. The monopolistic competitor’s supply curve is part of its marginal cost curve.
d. The demand curve of a monopolistic competitor is downward sloping.
