Explain the purchasing power parity theory of exchange rates, using the euro-dollar exchange rate as an example.

Expert Solution

Solution-

Is a theory, which states that exchange rates between currencies are in equilibrium when their purchasing power of the same good is the same in each of the two countries.(MacEachern, A.) The reason for the purchasing power parity theory is because we must adjust values of currencies to give them their proper worth in comparison of each other. How we do this is with the formula below. "S" represents exchange rate of currency1 to currency 2"P1" represents the cost of good "x" in currency 1 "P2" represents the cost of good "x" in currency 2 (2016)

E = P / Pf

E represents the spot exchange rate

P is the domestic price index

Pf is the foreign price index

Therefore, if something is the United States cost 5,000 US dollars and the same good cost 2,500 Euros in Europe then their exchange rate would be 2:1.

In order to hold the purchasing power parity if either currency were to fluctuate due to various reasons like inflation or other monetary acts the ratio would have to change to account for the currencies value change.

Purchasing power parity is a neoclassical economic theory that states that the exchange rate between two countries is equal to the ratio of the currencies' respective purchasing power. The OECD defines GNP as "an aggregate measure of production equal to the sum of the gross values added of all resident and institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs).” The gross national income (GNI) is the...

Law of one price and Purchasing-power-parity theory We employ a theory called the Purchasing Power Parity to explain the movement of nominal exchange rate. The PPP theory is built on the Law of One Price, which states that a currency must have the same purchasing power in all countries. Based one this assumption, PPP theory establishes the functional relationship between Nominal exchange rate, domestic price level, and foreign price level. Suppose you are provided with the following information: 1) P...

Exchange rates are affected by the law of one price and purchasing power parity (PPP) in the long-run. Exchange rates are affected by the interest-rate parity condition in the short-run (Interest rate on domestic bond = Interest rate on foreign bond minus Expected appreciation of the domestic currency). What do these mean?
