- Trade or elasticities approach
- The theory or approach that stresses the role of trade or the flow of goods and services in the determination of exchange rates. More useful in the long run, than short run. Can't explain 1. the large volatility of exchange rates over the past three decades 2. the sharp appreciation of the dollar from 1980-85 and 1995-2002 or 2. the failure of the U.S. trade deficits to decline when the dollar depreciated sharply from 85-88 and 02-04.
- Purchasing Power Parity (PPP) theory
- The theory that postulates that the change in the exchange rate between two currencies is proportional to the change in the ratio in the two contries general price levels.
- Absolute purchasing power parity theory
- Postulates that the equilibrium exchange rate is equal to the ratio of the price levels in the two nations. This version of the PPP theory can be very misleading. R=P/P*
- Law of one price
- The proposition that in the absence of transportation costs, tariffs and other obstructions to the free flow of trade, the price of each homogeneous (identical) traded commodity will be equalized in all markets by commodity arbitrage.
- Relative purchasing power parity theory
- the theory that postulates that the percentage change in the exchange rate is equal to the difference in the percentage change in the price level in the two countries. dR=dP/dP*
- Monetary model of exchange rates
- The theory that postulates that exchange rates are determined in the process of equilibrating or balancing the stock or total demand and supply of money in each nation.
