Find an SPNE where the path of play in which two players play (M, f), (F, m), (M, f), (F, m), ... is part of the SPNE. (5) (a) Write down the SPNE clearly. (15) (b) Prove that there is no deviation on the equilibrium path. Clearly show the range of d. (10) (c) Prove that there is no deviation off the equilibrium path. Clearly show the range of d
