下列报道摘自《美元坚挺的惊讶》(Dollar's Strength a Surprise),《纽约时报》,p.D1,1989-08-07:
“但是,现在有一种观点认为,经济正在朝”软着陆“的方向行进,经济增长明显放慢,通货膨胀率降低,但经济衰退并没有发生。
这种前景对美元的坚挺是有利的。原因有二:第一,软着陆不像衰退那样具有破坏性,因此,支撑美元的外国投资很可能持续下去:
第二,软着陆不会迫使美联储为刺激增长而降低利率。利率下降会对美元产生贬值的压力,这是因为,利率下降会使美元证券对外国人的吸引力下降,诱使人们抛出美元。此外。由软着陆预期而产生的乐观因素甚至可以抵消一些由利率下降带给美元的贬值压力。”
a.试用本章所学的汇率决定模型解释报道的第三段。
b.还有什么汇率决定因素有助于解释第二段?
The following report appeared in the New York Times on August 7,1989(“Dollar's Strength a Surprise,”p.DI):
But now the sentiment is that the economy is heading for a“soft landing”with the economy slowing significantly and inflation subsiding,but without a recession.
This outlook is good for the dollar for two reasons.A soft landing is not as disruptive as a recession,so the foreign investments that support the dollar are more likely to continue.
Also,a soft landing would not force the Federal Reserve to push interest rates sharply lower to stimulate growth.Falling interest rates can put downward pressure on the dollar because they make investments in dollar-denominated securities less attractive to foreigners,prompting the selling of dollars.In addition,the optimism sparked by the expectation of a soft landing can even offset some of the pressure on the dollar from lower interest rates.
a.Show how you would interpret the third paragraph of this report using this chapter's model of exchange rate determination.
b.What additional factors in exchange rate determination might help you explain the second paragraph?

参考答案

a.根据利率平价条件
在预期汇率保持不变的情况下,美联储降低利率会对美元产生贬值的压力。美联储降低利率将会使美元存款的收益曲线从R左移到R',均衡汇率从E上升到E',从而美元出现贬值。
如果经济实现“软着陆”,美联储不降低利率,则这种美元贬值不会发生。但是,美联储实际上降低了利率,即利率从R降低为R'。经济实现软着陆时,人们预期未来的汇率会出现升值,使得预期的美元存款的预期收益曲线从II左移到I'I',该曲线的移动反映了由软着陆而产生的乐观因素,预期的变化意味着随着美元利率从R降为R',汇率从E贬值为E",而不是从E贬值为E*(此时不存在预期的变化)。
b.经济衰退的破坏性作用会使得持有的美元资产面临更大的风险。风险资产必须提供一些额外的补偿,才能使人们愿意持有它们,而不是选择风险较小的资产。这种额外的补偿会以所持有资产的标价货币预期价值更大幅度上升的形式表现出来。但是,在预期未来汇率既定的情况下,标价货币更大幅度的升值只能在现行货币价值更大幅度的贬损的基础上发生。因此,具有破坏性的衰退将使得美元资产风险增大,从而导致当前美元大幅贬值。而软着陆却可以避免经济出现衰退时的这种破坏性作用。
