Sometimes oligopolies in the same industry are very different in size. Suppose we have a duopoly where one firm (Film A) is large and the other film (Film B) is small, as the prisoners dilemma box in Table 10.4 shows. Assuming that both films know the payoffs, what is the likely outcome in this case?

May and Raj me the only two growers who provide organically grown corn to a local grocery store. They know that if they cooperated and produced less corn, they could raise the price of the com. If they work independently, they will each earn 100. If they decide to work together and both lower their output, they call each earn 150. If one person lowers output and the other does not, the person who lowers output will earn $1 and the other person will capture the entire market and will earn 200. Table 10.6 represents the choices available to Mary and Raj. What is the best choice for Raj if he is sole that Mary will cooperate? If Mary thinks Raj will cheat, what should Mary do and why? What is the prisoners dilemma result? What is the preferred choice if they could ensure cooperation? A = Work independently; B = Cooperate and Lower Output. (Each results entry lists Rajs earnings first, and Marys earnings second.)

Jane and Bill are apprehended for a bank robbery. They are taken into separate rooms and questioned by the police about their involvement in the crime. The police tell them each that if they confess and turn the other person in, they will receive a fighter sentence. If they both confess, they will be each be sentenced to 30 years.

Does Jane have a dominant strategy? Does Bill have a dominant strategy? A = Confess; B = Stay Silent. (Each results entry lists Janes sentence first (in years), and Bills sentence second.)
