Answer:
Consider a Caribbean cruise route served by two cruise lines, Carnival and Royal Caribbean. Both lines must choose whether to charge a high price ($320) or a low price ($300) to vacationers. These price strategies with corresponding profits are illustrated in the payoff matrix to the right. Carnival's profits are in red and Royal Caribbean's are in blue. Suppose the cruise lines decide to collude. At which outcome are joint profits maximized?
Joint profits are maximized when Carnival picks $320 and Royal Caribbean picks $320.
Explanation:
When Carnival picks $320 and Royal Caribbean picks $320, then joint profits are maximized.
Nash equilibrium would exist only when Royal chooses $300 and the carnival chooses $300.
However, if both Carnival and Royal Caribbean charge a lower price, both of them can earn a higher profit.
