Calculate the following exchange rates (ZAR and USD refer to the South African Rand and U.S. dollar respectively):
1) The current ZAR spot rate in USD that would have been forecast by PPP.
2) Using IFE the expected ZAR spot rate in USD one year from now.
3) Using PPP the expected ZAR spot rate in USD four years from now.
