Problem
Suppose the two firms A & B are selling competing products and are deciding whether to undertake strategy X or strategy Y. The possible outcomes of the game are given below with strategic form where the first number in each cell is a payoff to firm A and the second is the payoff to firm B and the payoffs are profits of the firms. Firm B Strategy X 150,75 225,0 150,30 Firm A 90,120 Strategy Y minimize its total cost. Strategy X Strategy Y A. Represent the game in extensive form B. Find the Nash equilibrium of the game.
