2. (5 points) Consider the strategic-form game G4 below, where x, y, s, t ER are parameters. (a) What are the conditions on the parameters of this game (r. y. s and t) for the Row player's action u to be strictly dominated? (b) What are the conditions on the parameters for (u, L) to be a Nash equilibrium of this game? (c) Suppose that we know that (u, L) and (d, R) are two strict Nash equilibria of the game. Is there a mixed strategy Nash equilibrium here? If there is, what is it? Figure 1: Strategie-form game Ga Column: L R " Row: ,t d 3,3
