Essay

Suppose the real exchange rate X between Canada and the U.S.is constant.Let the price level in Canada be P,the price level in the U.S.be P*,and the nominal exchange rate be
e. Suppose the price level in Canada increases from P₁ to P₂ and the price level in the U.S. increases from P₁* to P₂*. Show that the rate of change in e, which is equal to (e₂ - e₁)/e₁ × 100 is approximately equal to the difference in the inflation rates in the two countries. Note that the nominal exchange rate is e = XP*/P. What have you learned from this exercise?
