According to the Mundell”Fleming model, under:
A) floating exchange rates, a monetary expansion raises income whereas a fiscal
expansion does not, but under fixed exchange rates, a fiscal expansion raises income
whereas a monetary expansion does not.
B) both floating and fixed exchange rates, a monetary expansion raises income, but a
fiscal expansion does not.

C) be permanently higher and output will be permanently lower.
