18. Using the Exact International Fisher Effect [LO2] From our discussion of the Fisher effect in Chapter 7, we know that the actual relationship between a nominal rate, R, a real rate, r, and an inflation rate, h, can be written as: 1 + r = (1 + R)/(1 + h) This is the domestic Fisher effect. a. What is the nonapproximate form of the international Fisher effect? b. Based on your answer in part (a), what is the exact form for UIP? (Hint: Recall the exact form of IRP and use UFR.) c. What is the exact form for relative PPP? (Hint: Combine your previous two answers.)
