Consider the following game with three players: Player 1 first chooses between T and B. Then, after observing player 1's choice, Players 2 and 3 choose simultaneously between L and R. The two matrices below contain the payoffs associated with each combination of actions by the three players. Specifically, the left-hand side matrix contains the payoffs for each combination of actions by players 2 and 3 when player 1 chooses T; and the right-hand side matrix contains the payoffs for each combination of actions by players 2 and 3 when player 1 chooses B. Each cell of the matrices has a format (a, b, c), where a is the payoff of player 1; b is the payoff of player 2; and c the payoff of player 3. For example, if player 1 initially chooses T and players 2 and 3 choose L and L, then the payoff for player 1 is 3, the payoff for player 2 is 1 and the payoff for player 3 is 1.

6. Consider the following game with three players: Player 1 first chooses between T and
B. Then, after observing player 1's choice, Players 2 and 3 choose simultaneously
between L and R.
The two matrices below contain the payoffs associated with each combination of actions
by the three players. Specifically, the left-hand side matrix contains the payoffs for each
combination of actions by players 2 and 3 when player 1 chooses T; and the right-hand
side matrix contains the payoffs for each combination of actions by players 2 and 3
when player 1 chooses B. Each cell of the matrices has a format (a, b, c), where a is
the payoff of player 1; b is the payoff of player 2; and c the payoff of player 3. For
example, if player 1 initially chooses T and players 2 and 3 choose L and L, then the
payoff for player 1 is 3, the payoff for player 2 is 1 and the payoff for player 3 is 1.
In this setting, which of the following is true?
Player 2 L
Player 3

3, 1, 1

(a) If player 1 chooses T, Players 2 and 3 will get (3,3) as their payoffs
(b) If player 1 chooses T, Players 2 and 3 will get (1,1) as their payoffs
(c) Player 1 will choose B
(d) Player 1 will be indifferent between choosing B and T
(e) There is no pure-strategy SPNE

Expert Solution

Step 1

Given:

The game has 3 players.

Player 1 first chooses between T and B. Then, after seeing player 1's choice, Players 2 and 3 choose simultaneously between L and R.

Nash equilibrium:

In game theory, a Nash equilibrium is a concept used to describe a situation in which each player in a game chooses a strategy that is best for them, given the strategies chosen by the other players. In other words, a Nash equilibrium is a state in which no player can improve their payoff by changing their strategy, assuming that all other players keep their strategies the same.

Formally, a Nash equilibrium is a set of strategies (one for each player) in which each player's strategy is the best response to the strategies chosen by the other players. This means that if any player were to change their strategy, they would be worse off.

Nash equilibrium is named after John Nash, a mathematician and economist who introduced the concept in his 1951 paper "Non-Cooperative Games". It is a fundamental concept in game theory and has numerous applications in economics, political science, psychology, and other social sciences.
