35、tries have improved. What happens to U.S. net capital outflow? What happens to the U.S. real interest rate?ANS:U.S. net capital outflow will increase. The increase in net capital outflow increases the U.S. demand for loanable funds, which increases U.S. interest rates.DIF:2REF:32-1NAT:AnalyticLOC:In

37、e relative to foreign goods. This induces U.S. citizens to buy more goods overseas, which increases U.S. imports. The appreciation also induces foreign citizens to buy fewer U.S. goods, so U.S. exports fall. The decline in exports and increase in imports decreases net exports, and so the demand for

38、U.S. dollars declines. The inverse relation between the exchange rate and the quantity of U.S. dollars demanded in the foreign-currency exchange market is represented by the downward-sloping demand curve.DIF:2REF:32-1NAT:AnalyticLOC:International trade and financeTOP:Market for foreign-currency exch

39、angeMSC:Interpretive5.How are the identities S = NCO + I and NCO = NX related to the foreign currency exchange market and the loanable funds market?ANS:S is national saving, which is the source of loanable funds supply. NCO + I is net capital outflow plus domestic investment, which is the source of

40、demand in the loanable funds market. NCO is the source of supply in the foreign-currency exchange market. NX is net exports, which is the source of demand in the foreign-currency exchange market.DIF:2REF:32-1NAT:AnalyticLOC:International trade and financeTOP:Saving in an open economy | Open-economy

41、macroeconomic modelMSC:Interpretive6.Explain how an increase in the demand for capital goods in the U.S. can lead to a change in the U.S. exchange rate.ANS:An increase in demand for capital goods is an increase in investment demand. As investment demand increases, the demand for loanable funds shift

42、s right. This shift leads to an increase in the real interest rate. The increase in the interest rate reduces net capital outflow. The reduction in net capital outflow shifts the supply of currency in the foreign exchange market to the left, raising the real exchange rate.DIF:2REF:32-1NAT:AnalyticLO

43、C:International trade and financeTOP:Saving in an open economy | Open-economy macroeconomic modelMSC:Interpretive7.Suppose that U.S. citizens start saving more. What does this imply about the supply of loanable funds and the equilibrium real interest rate? What happens to the real exchange rate?ANS:

44、The supply of loanable funds increases, and the equilibrium real interest rate falls. Because of the lower interest rate, U.S. net capital outflow rises. This increase makes the supply of dollars shift to the right, and the real exchange rate of the dollar depreciates.DIF:2REF:32-3NAT:AnalyticLOC:In

45、ternational trade and financeTOP:Saving policyMSC:Analytical8.Suppose that the Turkish government budget deficit increases. What curves in the open-economy macroeconomic model shift? Explain why each curve shifts the direction it does.ANS:The supply of Turkish loanable funds curve shifts left becaus

46、e the government deficit decreases national saving. As the supply of loanable funds shifts left, the Turkish interest rate rises. This increase in the interest rate causes the quantity of Turkish net capital outflow to fall, which means that people will be supplying fewer Turkish dinar in order to purchase foreign assets. So the supply of dinar in the foreign-currency exchange market shifts left.DIF:2REF:32-3NAT:AnalyticLOC:International trade and financeTOP:Bud
