The two pure-strategy Nash equilibria of this game are (X,X) and
(Y,Y). That is, if the players are jointly playing either of those
combinations of strategies, neither has an incentive to deviate.
Their response is a best response to the other players'
actions.
When this game is played in the laboratory, about 3/4 of the row
players (player A) choose X while about 3/4 of the column players
(player B) choose Y.
This outcome is striking. The players mis-coordinate: there is a
high chance that they both get nothing. Furthermore, each player
tries to coordinate on the strategy that the other player would be
better off coordinating on. That is, Player A receives 6 from
successful coordination choosing X, which is less than the 6.1
Player A would get from coordinating on Y.
Suppose players in this game think according to the level-k
model. Assume a Level-0 agent randomises between options with equal
probability.
a) What would player A and player B do if they were level-1
players? [1 mark]
b) What would player A and player B do if they were level-2
players? [1 mark]
c) What would player A and player B do if they were level-3
players? [1 mark]
d) Given your answers to a) through c), how might a mix of
level-k players explain the mis-coordination described above? [2
marks]
For all four questions, remember the idea behind level-k
thinking: given their own cognitive level, a player forms an
expectation of what others will do and tries to be "one step ahead
of them".
