Question 37
In a community of 1000 people, there are 300 type A people whose native language is Language A and 700 type B people with native language B. Everyone can speak and understand his or her native language. A native speaker of Language A can learn language B at cost CA ≥ 0 and a native speaker of Language B can learn language A at cost CB ≥ 0. The value to anyone of being able to speak to and understand another person is 1 per person. Based on the above data, answer the given subquestions.
For what values of CA and CB, would there be a Nash equilibrium in which the type B’s learned language A and the type A’s did not learn language B. CB should be
CB ≤ 700
CB ≥ 700
CB ≥ 300
CB ≤ 300
