Ans. Both A and C.
All the secure strategies results in a Nash equilibrium. A Nash equilibrium is said to be a subgame perfect equilibrium if and only if it is a Nash equilibrium in every subgame of the game. A pure Nash equilibrium is a strategy profile in which no player would benefit from deviating, given that all other players do not deviate. Thus, all Nash equilibrium are perfect equilibrium.

Please show step by step and explanation: “All subgame perfect equilibria are Nash equilibria.” Is that claim true or false? If it is true, explain why so. If it is false, prove this point by constructing a counterexample to the claim (i.e. a game in which there is a subgame perfect equilibrium which is not a Nash equilibrium).

There can be more than one Nash Equilibrium or no Nash Equilibrium at all. In the following game HA and CA are trying to decide which segment of the market to appeal to with advertising, prices,special promotions, etc. Each firm has two strategies available: appeal high income customers, or appeal to lower income customers. ^If both try to appeal to high income customers they will directly compete against each other and each firm gets a payoff of 50. ^If both...
