Question

Draw the relevant game tree associated the sequential game described above. Clearly label nodes/information sets, who moves at each node/information sets, actions, payoffs (at terminal nodes).

Boeing is the sole supplier of aircrafts to all Asian airlines. Airbus is deciding whether to
enter the Asian market and compete with Boeing.
Airbus can take an (a) aggressive entry strategy which we refer to as E1. Airbus can also
take a (b) soft entry strategy which we refer to as E2. Finally, Airbus can completely (c)
stay out of the market which we refer to as O(ut).
• Boeing can decide to engage in price war (P) or share (S) the market with Airbus
Airbus chooses first between E1, E2, and O, after which Boeing chooses between P and S.
(i) If Airbus stays out of the market, Boeing gets 4, Airbus gets 0
(ii) If Airbus chooses E1 or E2 but Boeing chooses P, each gets (- 1)
(iii) If Airbus chooses E1 and Boeing chooses S, Airbus gets 3, Boeing gets 1
(iv)If Airbus chooses E2 and Boeing chooses S, Airbus gets 2, Boeing gets 2
• Moving second, Boeing knows whether Airbus has chosen to stay out or enter, but it does
not know whether Airbus has chosen E1 or E2. [Hint: think of information set]
