Compute the Nash equilibria of the following location game. There are two people who simultaneously select numbers between zero and one. Suppose player 1 chooses s1 and player 2 chooses s2 . If si < sj , then player i gets a payoff of (si + sj )>2 and player j obtains 1 − (si + sj )>2, for i = 1, 2. If s1 = s2 , then both players get a payoff of 1>2. Please make sure to...

QUESTION 15 Consider the following simultaneous-move game: Two firms, Firm 1 (raw player) and Firm 2 (column player), decide whether to enter (E) or not enter (N) some market. If neither enters, then both make 0. If both enter, the market is oversaturated and so both earn a loss of 5. However, if only one enters, then the entrant earns monopoly profit of 10. Which of the following matrices is the correct representation of the static game? 0.10 10.0 0.0...
