NO.PZ2023071902000047 问题如下 QuestionSuppose the nominspot exchange rate (CAJPY) rises 6.2%, the Japprilevel ops 3.8%, anthe Canaprilevel escalates 1.8%. The alteration in the reexchange rate (%) is most nearly: A.0.36%. B.–0.66%. C.1.8%. SolutionThe formula for the reexchange rate is:Reexchange rate = Nominspot exchange rate × (CPI of the foreign nation/CPI of the home nation)Change in the reexchange rate = [(1 + Change in exchange rate) × (1 + Change in prilevel in foreign nation)]/(1 + Change in prilevel in home nation) – 1= [(1 + 6.2%) × (1 - 3.8%)]/(1 + 1.8%) - 1 = 0.36%The Foreign Exchange Market anCapitFlows• scrithe foreign exchange market, inclung its functions anparticipants, stinguish between nominanreexchange rates, ancalculate aninterpret the percentage change in a currenrelative to another currency实际汇率的计算公式为:实际汇率=名义即期汇率×(外国CPI /本国CPI)实际汇率变化量=[(1 +汇率变化量)×(1 +国外价格水平变化量)]/(1 +本国价格水平变化量)- 1=[(1 + 6.2%)×(1 - 3.8%)/ (1 + 1.8%)- 1 = 0.36% 感觉有些题目里是F/但像这道题目又是F，在题目没有明确说明的情况下如何判断呢
