Question 33
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 nobody learned the other group’s language? CA should be
CA ≤ 700
CA ≥ 700
CA ≤ 500
CA ≥ 500
