Question
Consider the p-beauty contest game.
a group of people wrote down a number
between 1 and 100.
2/3rd of the average of all the numbers was
calculated.
Whoever's answer was closest to the value wins.
(a) Write down a game representing this
situation. You will have to make some
assumptions about the utility of the players.
Make sure you state your assumptions explicitly.
(b) Which actions are strictly dominated?
(c) Which actions are weakly dominated?
(d) Suppose that Jim is a student in the class. Jim
is rational and thinks that all of his classmates
are cautious and will not play weakly dominated
actions. Based on this information alone, what
can you conclude about Jim's choice?
