Two players can name a positive integer number from 1 to 6. If the sum of the two numbers does not exceed 6 each player obtains payoff equal to the number that the player named. If the sum exceeds 6, the player who named the lower number obtains the payoff equal to that number and the other player obtains a payoff equal to the difference between 6 and the lower number. If the sum exceeds 6 and both numbers are...

In the “divide two apples” game, player 1 suggests a division scheme (x,y) from the set {(2, 0), (1, 1), (0, 2)} where x is the number of apples allocated to player 1, and y is the number of apples allocated to player 2. Player 2 counters with a division scheme of her own that comes from the same set. The final allocation is obtained by averaging the two proposed division schemes. The apples can be cut if the resulting...
