Homework Answers
Gun and Show strategy for Mugger is weakly dominated by
the Gun and Hide strategy.
Because, if he follows this, he may have a payoff of 3 or
4 depending on Simon's reaction. However,, the strategy
Gun and Hide would always yield better payoffs of 3 or
5!
While the payoff is 3, when Simon chooses "Resist strategy is
common in both strategies of the Mugger, Gun and Hide strategy
yields a payoff 5 when Simon chooses "Do not
resist" while Gun and Show yields the payoff
4.
Hence, the mugger would always choose Gun and Hide over Gun and
Show.
Hence the strategy Gun and Show is Weakly Dominated.
There is no strongly dominated or strongly dominant strategy here,
as the payoffs in any one trategy are not absolutely greater than
payoffs in any other strategy.
Let me know if any queries.
