Part B Consider now s three-period American put option pricing model. Under these conditions, we will have the terminal prices, Puuu = max { A - uuuSo, 0} (13) Puud = Pudu = Pduu = max { X - uudSo, 0} (14) Padu = Paud = Pudd = max { X - dduSo, 0} (15) Padd = max { X - dddSo, 0} (16) Calculate Puu, Pud and Pad then Pu, Pa and then Po for u = 1.15, d = 0.85, r = 0.045, So = $45 for strikes X = $40, $45, $50. Compare these to European put options with the same inputs. Calculate the early-exercise premiums: EEPO = Po - Po (17)
