Answer to Question 2
If the U.S. exchange rate falls, the quantity of U.S. dollars demanded increases for two reasons. The first is the exports effect. If the exchange rate falls, then U.S. goods and services are cheaper in foreign nations. These nations increase the amount of U.S. exports they demand. As exports increase the quantity of dollars demanded increases so that the importing nations can pay for the exports. The second reason the quantity of U.S. dollars demanded increases is the expected profit effect. In general, the greater the expected profit from holding U.S. dollars, the greater is the quantity demanded of U.S. dollars. When the exchange rate falls, more people will believe that it will rise again in the future and so more people want to hold U.S. dollars. As a result, the quantity of U.S. dollars demanded increases.
