Suppose that relative purchasing-power parity holds and that the inflation rate in Germany is expected to bee 2% over the next year. What is the expected inflation rate in the United States?

Explanation / Answer

sol A)(ig-ius)/(1+ius) = (F-E)/E (7%-4%)/1.04 = 1.2/E -1 1.028846154 =1.2/E E =1.166 the exchange rate today=$1.166 per Euro B) If real interest rates are equal, then ig-ius= pja-pus= (F-E)/E 2% -pus =0.028846154 pus = -0.88% expected inflation rate in the United States=-0.88%
