Purchasing Power Parity (PPP) - Theory: Exchange rates adjust to equalize the price of a basket of goods between two countries. - Implication: Long-term exchange rates are determined by relative inflation rates. 2. Interest Rate Parity (IRP) - Theory: Exchange rate differences reflect interest rate disparities between countries. - Implication: Investors will adjust their investments across borders, causing the exchange rate to reflect interest rate differences. 3. Monetary Model - Theory: Exchange rates are influenced by money supply and demand in different countries. - Implication: A country with higher inflation or money supply growth will see its currency depreciate. 4. Asset Market Model - Theory: Exchange rates are determined by demand for financial assets denominated in different currencies. - Implication: Expectations about economic conditions and interest rates affect exchange rates. 5. Balance of Payments Model - Theory: Exchange rates are influenced by the trade balance and capital flows between countries. - **Implication**: A trade surplus leads to currency appreciation as foreign buyers need the local currency. 6. Mundell-Fleming Model - Theory: Combines fiscal and monetary policies with capital mobility to explain exchange rate movements in an open economy. - Implication: Exchange rates are affected by government policies and international capital flows. 7. Government Intervention - Theory: Governments may intervene to stabilize or influence exchange rates. - Implication: In managed floating systems, exchange rates can be influenced by both market forces and government actions.
