Suppose the American Medical Association successfully lobbied Congress to pass a law that required all licensed medical doctors have medical degrees from U.S. medical schools.

1. How would this requirement affect the market for medical degrees in the U.S.? Graph and explain your answer in one or two sentences. What would happen to tuition and the number of degrees conferred?
2. How would this requirement affect the market for medical degrees at universities outside the U.S.? Again, graph your answer and explain what would happen to both tuition and the number of degrees conferred.
3. Suppose that the requirement were instead that all doctors in the U.S. had to be U.S. citizens, but there was no requirement that doctors have medical degrees from U.S. universities. How would this policy change your answers to Parts A and B?
