A subgame perfect equilibrium is when: Group of answer choicesEvery player’s strategy is a Nash equilibrium in every subgame (part of the game).Players adopt strategies to maximise the total payoff to players in the game.Every player adopts a strategy that they would credible implement if they were ever required to.a and c.None of the above.

If each player in a game has a strictly dominant strategy, then:Group of answer choicesthe Nash equilibrium is welfare-maximising.each player achieves a maximum payoff in equilibrium.the game has no equilibrium.there cannot be multiple equilibria.the game can only played once.

In game theory, a Nash equilibrium is defined as:Group of answer choicesthe dominant strategy of each player.a set of strategies for which all players are choosing their best strategy, given the actions of the other players.the set of strategies that result in the maximum payoff to each player.the set of strategies chosen when the players in a game can cooperate with each other.

31. What is the Nash equilibrium in game theory?Group of answer choicesThe point where all players are happy with their outcomes.The final round of a game where all players must reveal their strategies.A strategy where one player dominates all others.A situation where no player can improve their payoff by changing their strategy unilaterally.

In an extensive form game, a subgame perfect Nash equilibrium (SPNE) strategy is always the same as the SPNE path.Group of answer choicesTrueFalse

Consider the following simultaneous stage game that is play twice. That is, there are two periods, and in each period the two players choose their actions simultaneously. The outcome in the first period is revealed before the players make their choices in the second period. Outline how in a subgame perfect equilibrium, it is possible to get (B, B) as the choice made in the first period. Explain the relevance to trust in organisations.
