Purchasing Power Parity Theory(PPP) is a theory, which establishes thefact that the exchange rates between currencies are in equilibrium in the event of equality in the purchasing power of each of the countries. It is more of a long run predictor than a day to day indicator of therelationship between changes in the price level and the exchange rate.
  • 19. Purchasing Power Parity Theory(PPP) the “law of one price” applies to individual commodities whereas PPP applies to the general price level • price of similar products to two countries should be “Law of one price” equal when measured in a common currency.
  • 20. Example: American steel $100 per ton, Japanese steel 10,000 yen per tonIf E = 50 yen/$ then prices are: American Steel Japanese SteelIn U.S. $100 $200In Japan 5000 yen 10,000 yenIf E = 100 yen/$ then prices are: American Steel Japanese SteelIn U.S. $100 $100In Japan 10,000 yen 10,000 yenLaw of one price  E = 100 yen/$
  • 21.  Anexample of one measure of the law of one price, which underlies purchase power parity, is the Big Mac Index
  • 22.  Range and quality of goods Trade barriers and nontradables Differences in price level measurement

Interest Rate ParityIt assumes that a countrys currencyexchange rate and risk-free interest rateare correlated, and that an arbitrageinvestor cannot profit through therelationship.• Interest rate parity is a financial theory that connects forward exchange rates, spot exchange rates, and nations individual interest .
  • 24. Interest Rate Parity Difference between Forward Exchange Rate and Spot Exchange Rate = Difference between the interest rates of two countriesThe Forward exchange rates are when an investor agrees to exchange a currency at a specified rate at a specified future date.A spot exchange rate is what the trader can get for his currency right now.
