15. Is it possible that an outright ban on foreign imports will have no effect on the equilibrium price? (Hint: Suppose that imports occur only at relatively high prices.) An import ban O A. would have an effect if domestic demand were positive at the equilibrium price. O B. would have no effect if the world price were less than the equilibrium price. O C. would have no effect if imports were zero at the equilibrium price. O D. would have no effect if domestic supply were zero at the equilibrium price. O E. would have an effect if the world price were equal to the domestic price
