3: Alex and Aaron are political rivals, and Aaron has challenged Alex to a duel.
Alex must choose whether to accept the challenge or decline, and Aaron must choose
whether to shoot Alex or miss (even if he accepts, Alex's religious convictions won't
allow him to shoot Aaron). If Alex declines, he lives but Aaron gets the satisfaction
of making Alex look like a coward. If Alex accepts and Aaron misses, both men get
to move on with their lives but Alex gets the benefit of defending his honor. If Alex
accepts and Aaron shoots, Alex will die but Aaron would have also killed his own
political career. The payoffs are represented in the payoff matrix below:
Aaron
Shoot Miss
Ассеpt
0,0
2,1
Alex
Decline
1,2
1,2
(1) What are the pure-strategy Nash equilibria of this game?
(2) Now suppose that the game is sequential. Alex first chooses whether to accept
or decline the challenge to a duel, and if Alex accepts Aaron then chooses
whether to shoot Alex or miss. In this version of the game, does one of the
Nash equilibria seem more rational than the other(s)? Why is that? Explain
your reasoning.
