Which of the following accurately describes a player's strictly dominant strategy? O It is a strategy that is better than all the player's other strategies, no matter what the other players do. There is always at least one player who has one in every game.. O It is the strategy a player uses in the Nash equilibrium of a game. Since a Nash equilibrium always exists, players always have a strictly dominant strategy. O It is a strategy that is better than all the player's other strategies, no matter what the other players do. A player may or may not have one. O It is a strategy that is better than all the player's other strategies, no matter what the other players do. Every player has a dominant strategy in every game.. O It is the strategy a player uses in the Nash equilibrium of a game. Since a Nash equilibrium may not exist, players may not always have a strictly dominant strategy.

Solve for the Nash equilibrium (or equilibria) in each of the following games. (a) The following two-by-two game is a little harder to solve since firm 2’spreferred strategy depends of what firm 1 does. But firm 1 has a dominantstrategy so this game has one Nash equilibrium. Firm 2 Launch Don’tFirm 1 Launch 60, -10 100, 0 Don’t 80, 30 120, 0 What is the Nash equilibrium of this simultaneous-move game? (b) What would the outcome of this game be if instead firm 1 moved first and then, after seeing what firm 1 chose, firm 2 chose it strategy? In this case firm 1 doesn’t necessarily need to choose a best response, but firm 2 must choose a best response since it moves second.
