【正确答案】 B

【答案解析】[解析] 27-30
Every change, in exchange, rate, whether upward or downward, helps some firms and individuals and hurts others. When a country"s currency appreciates, its export industries suffer, as do industries that compete with imports. However, consumers benefit from the availability of low - cost imports, and they profit from efforts by domestic producers to cut costs and improve quality in response to foreign competition. Mm, profits rise and the number of jobs increases in sectors that use imported mw materials and in those devoted to marketing and servicing imported goods.
When a country"s currency depreciates, the effects are reversed: consumers face higher prices; people who sell mad service imported goods suffer; but export industries boom, and import competing industries enjoy a respite from international competition. The former winners become the losers, and vise versa. These effects insure that exchange rates are a matter of constant concern for policymakers.
