How will a sustained appreciation of the U.S. dollar over time likely affect U.S. net exports?

What will be an ideal response?

The appreciation of the U.S. dollar should lead to reduced net exports as foreigners will find the purchasing power of their money falling relative to goods priced in U.S. dollars. Conversely, Americans will find foreign goods less expensive in terms of the U.S. dollars they need to exchange for foreign currency to buy foreign goods. Consequently, U.S. exports will fall and U.S. imports will rise, thus increasing net exports and contributing to an increase in aggregate expenditures.
