Global Financing and Exchange Rate Mechanisms Essay

Global Financing and Exchange Rate Mechanisms - Essay ExampleThe get Power Parity principle (PPP) was enunciated by a Swedish economist, Gustav Cassel in 1918. According to this theory, the monetary value levels (and the changes in these price levels) in different countries determine the give-and-take rate of these countries currencies. The basic tenet of this principle is that the exchange rates between various currencies reflect the purchasing power of these currencies. This tenet is based on the faithfulness of One Price.... It also makes a few additional assumptions. No transaction cost in the foreign currency markets It assumes that there are no costs involved in buying or selling a currency. Basket of commodities It also assumes that the same basket of commodities is consumed in the different countries, with the components being used in the same proportion. This factor, along with the Law of One Price, makes the overall price levels in different countries equal. Though the e xplanation provided by the commanding PPP is very candid and easy to understand, it is difficult to test the theory empirically. This is due to the fact that the indexes used in different countries to measure the price level may not be comparable due to-- the indexes being composed of different basket of commodities, due to different needsand tastes of the consumer.-- the components of the indexes being weighted differently due to their comparativerelevance,-- different base age being used for the indexes. Due to these reasons, these price indexes cannot be used to evaluate the validity of the theory.The relative form of PPP The absolute form of PPP describes the yoke between the spot exchange rate and price levels at a particular point of time. On the other hand, the relative form of PPP dialogue about the link between the changes in spot rates and in price levels over a period of time reflect the changes in the price levels over the same period in the concerned economies. Rel ative PPP relaxes a number of assumptions made by the Law of One Price and the absolute PPP.These are Absence of transaction costs Absence of transportation costs Absence of tariffs. The relaxation of these assumptions
