These are revision question for my upcoming test. They are from the textbook and are not graded.
Question 1
1.1 Two computer firms, A and B, are planning to market network systems for office
information management. Each firm can develop either a fast, high-quality system
(H), or a slower, low-quality system (L). Market research indicates that the resulting
profits to each firm for the alternative strategies are given by the following payoff
matrix:
Firm B
H
L
H
50, 40
60, 45
Firm A
L
55, 55
15, 20
1.1.1 If both firms make their decisions at the same time and follow maximin (low-risk)
strategies, what will the outcome be? With reference to the definition, explain how the
outcome is determined.
1.1.2 Suppose both firms try to maximise profits. What will the outcome be if Firm A can
commit first?
1.2
An industry with many stores offer laminating as a service to their customers.
Suppose that each store that offers this service has a cost function
C(q) = 50 +0.5q+0.08q² and a marginal cost MC=0.5 +0.16q. Suppose the going
rate for laminating is R8.50 per sleeve which each store is compelled to charge.
1.2.1
Is the industry in long run equilibrium? Use calculations to either prove or disprove
your findings.
1.2.2 Based on your answer in 1.2.1, identify two key features of long run equilibrium and
determine the price associated with this period.
