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.
a. 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)
b. Draw the payoff matrix for the normal form game associated with the sequential move game described above. State the two Nash equilibria in pure strategies.

Consider the two Nash equilibria found above. Is any one of them a Perfect Bayesian Equilibrium (PBE)? Explain. In particular, consider each NE and argue why they are or are not part of a PBE. [Note: A complete description of PBE must specify beliefs as a part of description of the equilibrium.]
