There are two mobile phone firms operating in a market; FF (Firm
1) and Wodaphone (Firm 2). The market demand is 𝑃𝑃 = 75 − 0.5(30𝑄1
+ 30𝑄2). The total costs for the two firms are 30𝑄1 and 30𝑄2.
(a) If either FF or Wodaphone enjoyed a monopoly position in
this market, what level of output would they produce?
(b) Using a diagram, fully labelled, describe how the
equilibrium outputs for the two firms are determined and solve
mathematically for this solution.
(c) The CEO of FF meets with her counterpart at Wodaphone and
suggests that the two firms each produce 22.5 units. The CEO of
Wodaphone accepts this suggestion. Why did the CEO of FF make this
suggestion, and why did her counterpart at Wodaphone agree? Show
this outcome on your diagram in (b).
(d) After keeping to this agreement for 12 months, the CEO of
Wodaphone notices that FF is actually producing more than 22.5
units. Why is FF doing this? Illustrate this on your diagram in
(b). What action can Wodaphone take against FF?
