不能理解inflation会导致本币贬值的算数逻辑

NO.PZ2020012102000011 问题如下 Fis a small country whose currenis the Fip. Three years ago, the exchange rate wconsireto reflecting purchasing power parity (PPP). Sinthen, the country’s inflation hexceeinflation in the other countries about 5% per annum. The Fip exchange rate, however, remainebroay unchange Whwoulyou have expectethe Fip exchange rate to show if PPP prevaile Are Fips over or unrvalue accorng to PPP? Accorng to PPP, to offset the effeof the higher inflation in Fap, the Fip shoulhave preciateagainst the other currencies approximately the fferenbetween Finflation anthin the other countries. Accorng to PPP, Fip is overvalue 解析根据购买力平价理论，为了抵消Fap中较高的通货膨胀的影响，Fip应该对其他货币贬值大约是Fap通货膨胀与其他国家之间的差额。根据购买力平价理论，Fip被高估了。 If PPP prevaile the Fip exchange rate will perciate about the fferenof inflaiton in the other countries about 5% per annum.The Fips are overvaluenow anwill perciate.
