Consider an infinitely repeated Bertrand oligopoly game with dis-
count factor d < 1. The unit cost of production is a constant
c = 0.2 and the same for all n > 2 firms. There are no fixed costs.
Describe a form of "trigger" strategies that can facilitate tacit collu-
sion in pricing. Determine the condition under which such strategies
can sustain the monopoly price in each of the following cases:
(a) The market demand in each period is D (p) = 1–p. (Calculate
the monopoly price and profit explicitly in your answer.)
