In: Economics
A sequential game with two-players 1 and 2, where player 1 has the first move advantage. Each player has two strategies, A and B. If both players choose A, each gets a payoff of 2. Both choose B, each gets a payoff of 3. For player 1 choose A and player 2 choose B, player 1 gets 4, and player 2 gets 1. If player 1 chooses B and player 2 choose A, player 1 gets a payoff of 1, and player 2 gets 4. How many, if there is any, subgame perfect equilibrium are there?
