Question
(In this and all other questions in which a game matrix is given, Player 1 chooses the row, Player 2 chooses the column, and if there is a Player 3, she chooses the matrix.)
Which is true for the following game according to the solution concept of iterated elimination of strongly dominated strategies?
A B C D a 4,3 -2,0 2,2 1,6 b 6,-1 4,-1 0,-2 0,-2 c 5,9 2,6 1,7 5,7
Player 1 is guaranteed a payoff of 6.
The strategy profiles (b,A) and (b,B) solve the game.
The unique strategy profile that solves the game is (c,A).
None of the other alternatives is true.
The unique strategy profile that solves the game is (b,A).
Strategy profiles (a,D) and (b,D) solve the game.
Solution
To solve this game using the concept of iterated elimination of strongly dominated strategies, we first need to identify if any strategies are strongly dominated.
A strategy is strongly dominated if there is another strategy that always results in a higher payoff, no matter what the other player does.
Looking at Player 1's strategies, we can see that strategy 'a' is not strongly dominated by any other strategy, because there is no other strategy that always results in a higher payoff. The same is true for strategies 'b' and 'c'.
Looking at Player 2's strategies, we can see that strategy 'A' is not strongly dominated by any other strategy, because there is no other strategy that always results in a higher payoff. The same is true for strategies 'B', 'C', and 'D'.
Therefore, we cannot eliminate any strategies using the concept of iterated elimination of strongly dominated strategies.
This means that the statement "Player 1 is guaranteed a payoff of 6" is not true, because Player 1's payoff depends on the strategies chosen by both players.
The statement "The strategy profiles (b,A) and (b,B) solve the game" is also not true, because these strategy profiles do not result in the highest possible payoff for both players.
The statement "The unique strategy profile that solves the game is (c,A)" is not true, because this strategy profile does not result in the highest possible payoff for both players.
The statement "The unique strategy profile that solves the game is (b,A)" is not true, because this strategy profile does not result in the highest possible payoff for both players.
The statement "Strategy profiles (a,D) and (b,D) solve the game" is not true, because these strategy profiles do not result in the highest possible payoff for both players.
Therefore, the correct answer is "None of the other alternatives is true."
