Dominant strategy refers to that strategy followed by one of the players in the game regardless of the strategy what the other player has adopted.
a)
Represent the table as follows:
Player 1 |
Player 2 |
|||
C |
D |
|||
Top |
Left |
Right |
||
Bottom |
A |
21,23 |
20,24 |
|
B |
22,16 |
19,18 |
Yes, player 2 has a dominant strategy C. (As player 2 gets higher pay off from strategy C).
b)
Yes, the game can be solved by elimination of dominated strategy.
If Strategy D for player 2 is eliminated, then the game is :
Player 2
Player 1 |
C |
|
A |
21,23 |
|
B |
22,16 |
Thus, the Nash equilibrium by eliminating dominated strategy is (A,C). (As row B is dominated by row, so it is eliminated).
c)
Represent the table as follows:
Player 1 |
Player 2 |
|||
C |
D |
|||
Top |
Left |
Right |
||
Bottom |
A |
21,28 |
28,27 |
|
B |
19,25 |
29,26 |
Thus, the Nash equilibrium is: (B,C) and (A,D).
