Answer to Question 1

D

Answer to Question 2

a) This is an example of an ultimatum game, and Player 1 should choose his optimal strategy using the process of backward induction, that is, by considering Player 2's decision first. If Player 1 offers a certain percentage of money to Player 2, Player 1 will definitely accept the offer because he prefers more money to less. Therefore, Player 1's optimal strategy is to offer the minimum possible amount to Player 2.
b) If Player 2 prefers fairness to money, he will not accept the offer in case Player 1 offers the lowest possible amount. If Player 1 knows that Player 2 prefers fairness to money, he will figure out that Player 2 will not accept the offer if he offers the lowest possible amount, leaving each of them with 0. Therefore, Player 1 will choose to offer a fair deal.
