Question:

Perhaps you have wondered what it could mean that €œthe meek shall inherit the earth.€ Here is an example, based on the discussion in the book. In a famous experiment, two psychologistsˆ— put two pigs€”a little one and a big one€”into a pen that had a lever at one end and a trough at the other end. When the lever was pressed, a serving of pigfeed would appear in a trough at the other end of the pen. If the little pig would press the lever, then the big pig would eat all of the pigfeed and keep the little pig from getting any. If the big pig pressed the lever, there would be time for the little pig to get some of the pigfeed before the big pig was able to run to the trough and push him away.
Let us represent this situation by a game, in which each pig has two possible strategies. One strategy is Press the Lever. The other strategy is Wait at the Trough. If both pigs wait at the trough, neither gets any feed. If both pigs press the lever, the big pig gets all of the feed and the little pig gets a poke in the ribs. If the little pig presses the lever and the big pig waits at the trough, the big pig gets all of the feed and the little pig has to watch in frustration. If the big pig presses the lever and the little pig waits at the trough, then the little pig is able to eat 2/3 of the feed before the big pig is able to push him away. The payoffs are as follows. (These numbers are just made up, but their relative sizes are consistent with the payoffs in the Baldwin-Meese experiment.)

(a) Is there a dominant strategy for the little pig? ___________ Is there a dominant strategy for the big pig? _______
(b) Find a Nash equilibrium for this game. Does the game have more than one Nash equilibrium? _____________ (Incidentally, while Baldwin and Meese did not interpret this experiment as a game, the result they observed was the result that would be predicted by Nash equilibrium.)
(c) Which pig gets more feed in Nash equilibrium? __________
