Select all statements that are false. [Note that this quesiton allows partial marks. Each correct answer is awarded equal marks, but if you choose a wrong answer you will be awarded negative marks, with a lower bound 0, so you do not receive negative score in any question. For example, if there are two true statements, then you are awarded 1 mark for each true statement you choose, and you are awarded -1 mark for each false statement you pick.] A subgame perfect equilibrium induces a Nash equilibrium in every subgame The set of Nash equilibria is strictly smaller than the set of subgame perfect Nash equilibria A finite extensive-form game has exactly one subgame perfect equilibrium A subgame perfect equilibrium is never based on non-credible threats
