Question
In the following dynamic game, Samuel is curious whether his friend
Jason is in love with one of their classmates. Before asking him directly, Samuel
can read Jason's diary or not. If he doesn't read the diary, he cannot discern
whether Jason is lying or not. Jason can tell if his diary has been read or not.
After Samuel chooses whether to read the diary or not, Jason decides whether
or not to lie about his feelings. In the event that Samuel has not read the diary,
he can then choose whether or not to believe Jason. The game tree with the
associated payoffs is shown below. The payoffs are ordered (Samuel, Jason).
(a.)
Find all Pure-Strategy Subgame Perfect Nash Equilibria in the
game. Show your work.
(b.)
Can you find any other Pure-Strategy Nash Equilibia that are not
subgame perfect? Show your work.
