- K In a game, there are two players: Player 1 and Player 2. They have two strategies to select from, A and B. Where the first payoff and the second payoff in every cell is for Player 1 and Player 2 respectively. Which of the following is an example of a game without a dominant strategy? (Check all that apply.) A. C. Player 1 Player 1 A B A B A 3,-3 1, 1 A 2,1 0,0 Player 2 Player 2 B 3, -3 5, -5 B 0,0 1,2 B. D.

However if either of them cheats on the other, they would get a payoff of 10, while the other person gets zero. If neither cheat, they stay with each other and get a payoff of 7 each and if both cheat, the relationship falls apart and each get a payoff of 1. What is the Nash equilibrium of this game? a. Cheat, Cheat b. Not cheat, Not cheat Sam cheats, Sarah doesn't Sarah cheats, Sam doesn'tThe following payoff matrix represents a simultaneous-move game between two players: Kay and Jack. Each player has two choices: Black or White. The first number in each cell is the payoff to Kay, and the second number is the payoff to Jack. Jay Black White 50, 30, Black 50 30 Кay 45, 40, White 30 50 Refer to the scenario above. Which is true? a. This game has a dominant strategy equilibrium. b. This game has two dominant strategy equilibria. c. This game has two Nash equilibria. d. This game has one Nash equilibrium.
- 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.1. A game may have more than one Nash equilibrium. T/F ? 2. A game has always at least one pure strategy Nash equilibrium. T/F? 3. A situation where everyone is playing a dominant strategy must be a Nash equilibrium.
