# Eco mcq-.suppose that two players are playing the following game.

1.Suppose that two players are playing the following game. Player A can choose either Top or Bottom, and Player B can choose either Left or Right.

Does Player A have a dominant strategy? If so, what is it?

A) Top is a dominant strategy for Player A

B) Bottom is a dominant strategy for Player A

C) Both of the above

D) None of the above

2.

8.

Now suppose the same game is played with the exception that Player A moves first and Player B moves second. Using the backward induction method discussed in the online class notes, what will be the outcome of the game?

A) Player A plays Top and Player B plays Left

B) Player A plays Bottom and Player B plays Left

C) Player A plays Top and Player B plays Right

D) Player A plays Bottom and Player B plays Right
