老师您好,这道题(详见图片)中提到由预期通胀的降低推测出output gap形成。但我笔记中只写了output gap的变化能推导出inflation的变化,反过来也成立吗? 还是说expected inflation降低->经济衰退或刚复苏->a large output gap?可以跳过对经济的预期而直接得出output gap形成的结论吗?谢谢。
21. A country with a persistent trade surplus is being pressured to let its currency appreciate. Which of the following best describes the adjustment that must occur if currency appreciation is to be effective in reducing the trade surplus? A. Domestic investment must decline relative to saving. B. Foreigners must increase investment relative to saving. C. Global capital flows must shift toward the domestic market. C选项,不是还有其他很多国家吗?这个国家升值不见得比其他国家多吧? 还有就是,为什么B不对呢?
已回答19. Acountrywithatradedeficit will most likely: A. have an offsetting capital account surplus. B. save enough to fund its investment spending. C. buy assets from foreigners to fund the imbalance. 还是不太明白为什么B不对,按照公式,B的话不是增加I吗?
