Response to the following problem:
Assume that the Australian dollar's spot rate is $.90 and that the Australian and U.S. 1-year interest rates are initially 6 percent. Then assume that the Australian 1- year interest rate increases by 5 percentage points, while the U.S. 1-year interest rate remains unchanged. Using this information and the international Fisher effect (IFE) theory, forecast the spot rate for 1 year ahead.
