Question 1
In a game, a dominated strategy is one where:
It is always the best strategy
It is always the worst strategy
It is the strategy that is the best among the group of worst possible strategies.
Is sometimes the best and sometimes the worst strategy
Question 2
To trust a potential cooperator until the first defection and then never cooperate thereafter is
a dominant strategy
an irrational strategy
a grim trigger strategy
a non-cooperative finite game strategy
a subgame imperfect strategy
Question 3
A key to analyzing subgame perfect equilibrium strategy in sequential games is
predictable behavior
an explicit order of play for at least some participants
information sets that are known with certainty
credible threats clearly communicated
randomness
Question 4
When there is no Equilibrium (or no Nash Equilibrium), we expect that:
