考虑一下由以下方程式所描述的经济: Y=C+I+G+NX Y=5000 G=1000 T=1000 C=250+0.75(Y-T) I=1000-50r NX=500-500ε r=r*=5 a.在这个经济中,求出国民储蓄、投资、贸易余额以及均衡汇率。 b.现在G增加到1250,求出国民储蓄、投资、贸易余额以及均衡汇率的值。解释你的结果。 c.现在假设世界利率从5%上升到10%(G又是1000),求出国民储蓄、投资、贸易余额以及均衡汇率的值。解释你的结果。 Consider an economy described by the following equations: Y=C+I+G+NX y=5000 G=1000 T=1000 C=250+0.75(Y-T) I=1000-50r NX=500-500ε r=r*=5 a.In this economy, solve for national saving, investment, the trade balance, and the equilibrium exchange rate. b.Suppose now that G rises to 1,250. Solve for national saving, investment, the trade balance, and the equilibrium exchange rate. Explain what you find. c.Now suppose that the world interest rate rises from 5 to 10 percent. (G is again 1,000). Solve for national saving, investment, the trade balance, and the equilibrium exchange rate. Explain what you find.
