C. chooses the best outcome for both players together
OD. chooses the best outcome for the other player
Sam and Sarah are thinking about getting married. 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't
Roger and Rafael play a game with the following rules. Roger is given $250 to divide between himself and Rafael. Rafael does not get to choose but he can reject Roger’s offer if he does not like it. If Rafael rejects, both get nothing. If Rafael accepts, both get the split that Roger decided.
a. What is this game called?
b. Find all Nash equilibria for this game.
c. When this game is played in the real world, do the predictions in part 1b materialize? Why/why not?
