Document Summary
Vanesa moves first: she buys a ticket either for the football match or for the opera. She shows miguel her ticket, so he knows what she has done. Then miguel moves: he buys his ticket either for the football match or for the opera. Cq: if vanesa moves first, what is true about : it is a nash equilibrium b) vanesa would deviate c) miguel would deviate d) none of the above. Yes, r, always r is a nash equilibrium, but it will not occur if both players are rational. This is because always r is not time-consistent, and a rational miguel would not follow it during the game and vanesa knows he won"t. So, if vanesa moves first, she will choose f , even if miguel says he will follow always r . To show this, we need a different model of the game: the extensive-form game.
