Refer to the accompanying game.   Firm A Firm B   Low Price High Price Low Price (10,9) (15,8) High Price (−10,7) (11,11)     What are the secure strategies for firm A and firm B, respectively?

Two rival companies competing in the same market need to decide their plans for future expansion of their stores. The Table below shows the possible outcomes of their mutually interdependent actions (payoffs are profits in £m)     Giga Company Titanic Conglomerate   No Change Refurbishment of existing stores Large Expansion No Change     30, 40      25, 35    15, 24 Refurbishment of existing stores     35, 30      28, 32    18, 33 Large Expansion     12, 22     18, 20    20, 25   The Nash equilibrium:            (A)       does not exist. (B)       occurs when both firms choose Refurbishment of existing stores.              (C)       occurs when both firms choose Large Expansion. (D)       occurs when both firms choose No Change.

See the extensive form game in the image attached (the payoffs of player 1 are written on top and the payoffs of player 2 are on the bottom).  a) Write this game in normal form (a player's strategy is a complete contingent plan that tells them what to play at each of their information sets) (b) Find all the Nash equilibria of the normal form game from part (a)

Finding Nash Equilibria Consider the following two player, normal form game: Player 1 Player 2 C L (2,1) U M (-2,-2) D R (2, -1) (1,2) (-1, 1) (0,0) (3,1) (0,0) (-1,-1) Find all pure and mixed strategy Nash equilibria. Calculate each player's expected payoffs at each equilibrium.
