A. Purchasing Power Parity (PPP)
6. Testing the Purchasing Power ParityTheory
a. Conceptual Tests of PPP
1.) choose two countries (say, the UnitedStates and a foreign country)
2.) compare the differential in their inflation rates to the percentagechange in the foreign currency’s
value during several time periods.

B. International Fisher Effect (IFE)
6. Why the international Fisher Effect Does
Not Occur
a. PPP does not hold in certain times
b. Since IFE based on PPP, it does
not hold consistently either
