Answer: E 6）The Balance of payments is always balanced. Discuss. Answer: True. Every international transaction automatically e

7、nters the balance of payments twice, once as a credit and once as a debit.Current account + financial account + capital account = 0 7) The balance of payments accounts seldom balance in practice. Discuss. Answer: True. The main reasons are due to the fact that data collected or received from differe

8、nt sources may differ in coverage, accuracy, and timing. In addition, data on services are not reliable as well as data from the financial account. Moreover, accurate measurements of international interest and dividend receipts are particularly difficult. 8）Fill in the following table: Answer: Chapt

Answer: C 7）Discuss the effects of a rise in the interest rate paid by euro deposits on the exchange rate. Answer: There are two effects to consider. If we make the unre

16、alistic assumption that the expected exchange rate will not change, then a rise in the interest rate paid by Euro deposits causes the dollar to depreciate. However, if the expected exchange rate were to rise, then the current exchange rate would also rise. (See figure 13-6 from the text.)8) Calculat

17、e the interest rate in the euro zone if interest parity condition holds, for the following 15 cases:Answer: Chapter 14 Money, Interest Rates, and Exchange Rates1）Money includes A) currency.

Answer: D 3）Using a figure describing both the U.S. money market and the foreign exchange market, analyze the effects of a temp

19、orary 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/

20、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.4) A permanent increase in a countrys money supply A) causes a more

21、than proportional increase in its price level. B) causes a less than proportional increase in its price level. C) causes a proportional increase in its price level.

D) the exchange rate smoothly appreciates in the short run. E) None of the above. Answer: A6）Although the price levels appear to display

23、 short-run stickiness in many countries, a change in the money supply creates immediate demand and cost pressures that eventually lead to future increase in the price level. Discuss. Answer: The statement is true. The pressures come from three main sources: excess demand for output and labor; inflat

24、ionary expectations; and, raw material prices. 7）The long run effects of money supply change: A) ambiguous effect on the long-run values of the interest rate or real output, a proportional change in the price levels long-run value in the opposite direction. B） proportional effect on the long-run val

25、ues of the interest rate or real output, a proportional change in the price levels long-run value in the same direction. C) no effect on the long-run values of the interest rate or real output, a proportional change in the price levels long-run value in the same direction. D) no effect on the long-r

26、un values of the interest rate or real output, no change in the price levels long-run value. E) ambiguous effect on the long-run values of the interest rate or real output, A disproportional change in the price levels long-run value in the same direction. Answer: CChapter 15 Price Levels and the Exc

27、hange Rate in the Long Run1）Under Purchasing Power Parity, A) E$/E = PUS/PE. B) E$/E = PE/PES. C) E$/E = PUS + PE. D) E$/E = PUS - PE. E) None of the above. Answer: A2）Assuming relative PPP, fill in the table below:Answer: 3) Under PPP (and by the Fisher Effect), all else equal, A) a rise in a count

28、rys expected inflation rate will eventually cause a more-than proportional rise in the interest rate that deposits of its currency offer in order to accommodate for the higher inflation. B) a fall in a countrys expected inflation rate will eventually cause an equal rise in the interest rate that dep

29、osits of its currency offer. C) a rise in a countrys expected inflation rate will eventually cause an equal rise in the interest rate that deposits of its currency offer. D) a rise in a countrys expected inflation rate will eventually cause a less than proportional rise in the interest rate that dep

30、osits of its currency offer to accommodate the rise in expected inflation. E) None of the above. Answer: C4）Describe the chain of events leading to exchange rate determination for the following cases:(a)An Increase in U.S. money supply(d)Increase in growth rate of U.S. money supply(c)Increase in wor

31、ld relative demand for U.S. products(d)Increase in relative U.S. output supply Answer: Chain of events leading to exchange rate determination: = (Pus/PE)Increase in U.S. money supply: Pus rises in proportion to the money supply; q remains the same. All dollar prices will rise (including dollar price

32、 of euro).Increase in growth rate of U.S. money supply: Inflation rate, dollar interest rate, Pus, E, rises in proportion to Pus.Increase in world relative demand for U.S. products: E falls, and q does as well.Increase in relative U.S. output supply: Dollar depreciates, lowers relative price of U.S.

33、 output, rise in q, effect on E is not clear since q and Pus work in opposite directions. 5）Which of the following statements is the most accurate? A) Relative PPP is not a reasonable approximation to the data. B) Relative PPP is sometimes a reasonable approximation to the data but often performs po

34、orly. C) Relative PPP is sometimes a reasonable approximation to the data. D) PPP is sometimes a reasonable approximation to the data. E) PPP is sometimes a reasonable approximation to the data but usually performs poorly. Answer: B 6) Interest rate differences between countries depend on A) differe

35、nces in expected inflation, but not on expected changes in the real exchange rate. B) differences in expected changes in the real exchange rate, but not on expected inflation. C) neither differences in expected inflation, nor on expected changes in the real exchange rate. D) differences in expected

36、inflation and nothing else. E) differences in expected inflation, and on expected changes in the real exchange rate. Answer: E 8) What is the real exchange rate between the dollar and the euro equal to? Answer: Let,Real dollar/euro exchange rate = Nominal exchange rate = Price of an unchanging baske

37、t in US = PusPrice of an unchanging basket in Europe = PEThen, = ( PE)/PusA rise in the real dollar/euro exchange rate is called a real depreciation of the dollar against the euro, a fall in purchasing power of the dollar.A fall in the real dollar/euro exchange rate is called a real appreciation of

38、the dollar against the euro, a rise in purchasing power of the dollar. Chapter 16 Output and the Exchange Rate in the Short Run1）A countrys domestic currencys real exchange rate, q, is best described by A) the price of similar goods in the same market.
