Return to the game given by the payoff matrix in

Problem 5.1.

a. Write down the extensive form for the simultaneous-move game.

b. Suppose the game is now sequential move,

with A moving first and then B. Write down

the extensive form for this sequential-move

game.

c. Write down the normal form for the sequential-move game. Find all the Nash equilibria.

Which Nash equilibrium is subgame-perfect?
