Answer: A Question Status: Previous Edition5) What are the main functions of money? Answer: Money serves in general three important functions: a medium of exchange; a unit of account; and a store of value. As a medium of exchange, money avoids going back to a barter economy, with the enormous search costs connected with it. As a unit of account, the use of money economizes on the number of prices an individual faces. Consider an economy with N goods, then one needs only (N - 1) prices. As a store of value, the use of money in general ensures that you can transfer wealth between periods.

Answer: A Question Status: Previous Edition6) What are the main factors determining the aggregate money demand? Answer: Three main factors: interest rate, the price level and real national income. A rise in the interest rate causes each individual in the economy to reduce her demand for money. If the price level rises, individual households and firms will spend more money than before. When real national income (GNP) rises the demand for money will rise. Question Status: Previous Edition7) Explain why one can write the demand for money as follows:Md = PxL (R, Y) Answer: The aggregate money demand is proportional to the price level. Imagine that all prices in an economy doubled, but the interest rate and everyones real incomes remained unchanged. Then, the money value of each individuals average daily transactions would then simply double, as would the amount of money each wishes to hold.

B) slopes downward because a fall in the interest rate reduces the desired real money holdings of each household and firm in the economy. C) has a zero slope because a fall in the interest rate keeps constant the desired real money holdings of each household and firm in the economy. D) slopes downward because a fall in the interest rate raises the desired real money holdings of each household and firm in the economy. E) None of the above.

B) its currency to appreciate in the foreign exchange market. C) does not affect its currency in the foreign market. D) does affect its currency in the foreign market in an ambiguous manor. E) affects other countries currency in the foreign market. Answer: B Question Status: Previous Edition7) What will be the effects of an increase in the money supply on the interest rate? Answer: An increase in the money supply will cause interest rate to decrease. This should increase investment and possibly consumption of durable goods. The reduction in the interest rate will cause a depreciation of the dollar. Question Status: Previous Edition8) What will be the effects of an increase in real output on the interest rate? Answer: An increase in real output will increase the interest rate. If investment depends only on interest rate, this will cause investment to go down. The increases interest rate will cause an appreciation of the dollar.

C) Given PUS and YUS, when the money supply decreases, the dollar interest rate declines and the dollar depreciates against the euro. D) Given PUS and YUS, when the money supply rises, the dollar interest rate declines and the dollar appreciates against the euro. E) Given PUS and YUS, when the money supply rises, the dollar interest rate declines and the dollar depreciates against the euro. Answer: E Question Status: Previous Edition3) Given PUS and YUS, A) An increase in the European money supply causes the euro to appreciate against the dollar, but it does not disturb the U.S. money market equilibrium. B) An increase in the European money supply causes the euro to appreciate against the dollar, and it creates excess demand for dollars in the U.S. money market. C) An increase in the European money supply causes the euro to depreciate against the dollar, and it creates excess demand for dollars in the U.S. money market. D) An increase in the European money supply causes the euro to depreciate against the dollar, but it does not disturb the U.S. money market equilibrium. E) None of the above. Answer: D Question Status: Previous Edition4) Analyze the effects of an increase in the European money supply on the dollar/euro exchange rate. Answer: The main points are: An increase in the European money supply will reduce the interest rate on the euro, and thus causes the euro to depreciates against the dollar. The U.S. money demand and money supply are not going to be affected, and thus the interest rate in the U.S. will remain the same. Question Status: Previous Edition5) Explain how the money markets of two countries are linked through the foreign exchange market. Answer: The monetary policy actions by the Fed affect the U.S. interest rate, changing the dollar/euro exchange rate that clears the foreign exchange market. The European System of Central Banks (ESCB) can affect the exchange rate by changing the European money supply and interest rate. Question Status: Previous Edition 6) What would be the effect of an increase in the European Money Supply in the Dollar Euro Exchange Rate? Answer: An increase in the European money supply lowers the dollar return on Euro deposits, i.e. the dollar appreciates against the Euro. There is no change in the US money market. Question Status: Previous Edition7) Using a figure describing both the U.S. money market and the foreign exchange market, analyze the effects of a temporary increase in the European money supply on the dollar/euro exchange rate. Answer: An increase in the European money supply will reduce the interest rate on the euro and thus will cause the schedule of the expected euro return expresses in dollars to shift down, causing a reduction in the dollar/euro exchange rate, i.e., an appreciation of the U.S. Dollar. The euro depreciates against the dollar. The U.S. money demand and money supply are not going to be affected, and thus the interest rate in the U.S. will remain the same. Question Status: Previous Edition 8) Using a figure describing both the U.S. money market and the foreign exchange market, analyze the effects of an increase in the U.S. money supply on the dollar/euro exchange rate. Answer: An increase in the U.S. money supply will cause interest rate to decrease. This should increase investment and possibly consumption of durable goods. The reduction in the interest rate will cause a movement to the left along the schedule depicting the expected euro return expressed in dollar. The result is an increase in E or a depreciation of the dollar. Question Status: Previous Edition 9) Explain the following figure. Answer: The figure explains how the money markets of two countries are linked through the foreign exchange market. The monetary policy actions by the Fed affect the U.S. interest rate, changing the dollar/euro exchange rate that clears the foreign exchange market. The European System of Central Banks (ESCB) can affect the exchange rate by changing the European money supply and interest rate. Question Status: Previous Edition 10) Combine the graph showing the interest parity condition and one showing money demand and supply to demonstrate simultaneous equilibrium in the money market and the foreign exchange market.How would an increase in the U.S. money supply affect the Dollar/Euro exchange rate and the U.S. interest rate? Illustrate your answer graphically and explain. Answer: Above the axis is depicted the foreign exchange market, where changes in the rate of return on the dollar are mapped into changes in the exchange rate. Below the axis is depicted the U.S. money market and shows the relation between the rate of return on the dollar and U.S. real money holdings. The mechanism works as follows. Consider an increase in the U.S. real money holdings. Supply and demand dictate that the demand for money must increase, so the rate of return must lower to equilibrate at point 2. The lower rate of return on the dollar will cause the dollar to depreciate (exchange rate moves to point 2).
