Solution for Homework 1
1. Each of three people announces a positive integer. If the three integers are dierent, the
person whose integer is closest to twice the average gets $100. If two or more integers are the same,
$100 is split equally between the pe
Homework 3
1. Consider the following game. Player 1 receives a card that is either
L or H with equal probabilities. Player 2 does not see the card. Player 1
may announce that the card is L and pay $1 to player 2. Player 1 may
also announce that the card i

1. Find all Nash equilibria (pure and mixed) of the game Chicken as it was introduced in
class.
Solution: The two pure strategy equilibria are (S, C) and (C, S). In addition to these, there
may be some mixed strategy equilibria. Le
