Effects of that depreciation or appreciation

Question

Would a decline in U.S. consumer income or a weakening of U.S. preferences for foreign products cause the dollar to depreciate or appreciate?  Other things equal, what would be the effects of that depreciation or appreciation on U.S. exports and imports?

Answer 1

A decline in U.S. incomes or a weakening of U.S. preferences for foreign goods would reduce U.S. imports, reducing U.S. demand for foreign currencies. These currencies would depreciate (the dollar would appreciate). Dollar appreciation means U.S. exports would decline and U.S. imports would increase.
