n analyst argues that exchange rate movements depend on interest rate differentials (that is, the International Fisher effect), country-specific economic policy uncertainty measures and country-specific GDP growth rates. With this in mind, the analyst estimates the following model: Expected rate of appreciation of yen against the dollar(%)= =0.5[idollar(%) – iyen(%)]+0.5[idollar(%) – iyen(%)]2+0.2[σUS(%) – σJAP(%)]+ +0.2[σUS(%) – σJAP(%)]2+0.1[GDPJAP(%) – GDPUS(%)]. In this model, idollar(%) is the one-year interest rate in the US, iyen(%) is the one-year interest rate in Japan, σUS(%) refers to economic policy uncertainty in the US, σJAP(%) refers to economic policy uncertainty in Japan, GDPUS(%) refers to annual GDP growth in the US and GDPJAP(%) refers to annual GDP growth in Japan. Assume idollar=6%, iyen=4%, σUS=5%, σJAP=1%, GDPUS=2% and GDPJAP=1%. Calculate the expected rate of appreciation of the yen against the dollar

Question
An analyst argues that exchange rate movements depend on interest rate differentials (that is, the International Fisher effect), country-specific economic policy uncertainty measures and country-specific GDP growth rates. With this in mind, the analyst estimates the following model: Expected rate of appreciation of yen against the dollar(%)= =0.5[idollar(%) – iyen(%)]+0.5[idollar(%) – iyen(%)]2+0.2[σUS(%) – σJAP(%)]+ +0.2[σUS(%) – σJAP(%)]2+0.1[GDPJAP(%) – GDPUS(%)]. In this model, idollar(%) is the one-year interest rate in the US, iyen(%) is the one-year interest rate in Japan, σUS(%) refers to economic policy uncertainty in the US, σJAP(%) refers to economic policy uncertainty in Japan, GDPUS(%) refers to annual GDP growth in the US and GDPJAP(%) refers to annual GDP growth in Japan. Assume idollar=6%, iyen=4%, σUS=5%, σJAP=1%, GDPUS=2% and GDPJAP=1%. Calculate the expected rate of appreciation of the yen against the dollar
