a) Explain why in a mixed strategy Nash equilibrium each player
must be indifferent between the pure strategies that are used in
her mixed strategy.
b) How will the mixed strategy Nash equilibrium be affected if
the payoff that the players get from both holding their investments
are increased (keeping all other payoffs the same)?
c) How can this change in mix probabilities be interpreted in
terms of the players' uncertain subjective beliefs?

6. Consider the following game: a. Identify all Nash Equilibria (Pure Strategy and Mixed) of this simultaneous game. b. Draw the two extensive form games that arise from each firm moving first. What are the Subgame Perfect Equilibria of these games? c. Identify a trigger strategy for each player that sustains (B,B) as an equilibrium. For what interest (discount) rates will this outcome be sustainable?

In some game theoretic scenarios, there is no Nash equilibrium while players play ‘pure strategies’. This results in players constantly switching their strategies to gain an advantage over their opponents. However, a balance can be achieved by players stochastically mixing the pure strategies, resulting in mixed strategy equilibriums.
