He believed that people would continue to populate the earth until output reached a subsistence level. On the other hand Kremer argues that population growth increased productivity allowing people to improve their standard of living despite growing population. Kremer argues that with more population comes more innovations. The improvements in technology more than offset any adverse impact of the increase in population on the standard of living.57. As shown in the graph below, the economy starts in equilibrium at point E0 with interest rate r0 and equilibrium quantity of saving and investment at q0. If the government succeeds in obtaining a surplus, there will be more public saving in the economy at each interest rate, and the supply of loanable funds curve will shift from S0 to S1. The new equilibrium will be at E1, with a lower interest rate, r1 and a higher quantity of saving and investment, q1. Hence, if the federal government succeeds in having a surplus, interest rates will fall and investment will increase.Market for Loanable Funds58. 1. Prices rise when the government prints too much money.2. There is a short-run tradeoff between inflation and unemployment.59. Inflation-indexed bonds are bonds whose interest and principal payments are adjusted upward for inflation, guaranteeing their real purchasing power in the future. They are important because they provide a safe, inflation-proof asset for savers and they may allow the Treasury to borrow more easily at a lower current cost.60. Examples in the text (or variations) include increased immigration, a decrease in the minimum wage, more generous unemployment insurance, an increase in the capital stock, an increase in the average level of education, a discovery of new mineral deposits, technology, and removal of barriers to international trade.61.See graph.Over time technological advances cause the long-run aggregate supply curve to shift right. Increases in the money supply cause the aggregate demand curve to shift right. Output growth puts downward pressure on the price level, but money supply growth contributes to rising prices.62. The reduction in the money supply raises the interest rate. So the return on bonds increases relative to the return on stocks. The increase in the interest rate also causes spending to fall so that revenues and profits fall making shares of ownership in corporations less valuable.63.The fiscal policy lags are mostly a matter of waiting to implement the policy. By the time the president and Congress can agree to and pass legislation changing expenditures or taxes, the recession may have ended. The Federal Reserve can act to change the money supply quickly, but it may take some time before the effects of an increase in the money supply work their way through the economy.64. 当政府支出30亿美元购买警车时,直接投资增加警车生产企业的利润,这种增加又使该企业雇佣更多工人,并增加生的。

When you borrow $1,000 from a bank to buy a car to use in your pizza-delivery business, that is investment, because the car is a capital good.3. (10 points) All factors, that affect AD at a given price level, can be categorized to four groups according to which component of spending is most directly affect: (1)C, such as a tax cut/hike, a stock market boom/decline; (2) I, such as optimism/pessimism about the future, a fall/rise in interest rates due to an increase/decrease in money supply; (3)G, such as greater/smaller spending on defense or highway construction, (4)NX, such as a boom/recession overseas, an exchange-rate depreciation/appreciation.According to the production factors, the long-run AS may change arising from the following four sources which affect the natural rate of output: (1)K (physical capital or human capital ), such as the increase of the number of machines or that of college degrees;(2)L, such as an increase in immigration from abroad, the change of the natural rate of unemployment due to increasing minimum wage or the unemployment insurance system; (3)N (natural resources), such as a discovery of a new mineral deposit, good weather, a change in the availability of imported resources; (4)A, such as the advance of internet technology, other events that act like changes in technology.All these variables——K, L, N, A, shift the short-run AS curve too. Another important new variable that affect the short-run AS is the change of expected price level. A decrease in the expected price raises the AS in the short-run.In the short-run, the continuing increase in money can raise GDP for that there is unexpected price level. However, in the long run, the AS curve is vertical, as people adjust their expectedprice levels to the actual price level. so the increase of money which raise AD and price level but can not have the economy to grow continuously only by use of expansionary monetary policy.4. (15 points)e.a. If Chinese government decided it no longer wanted to buy U.S. assets, U.S. net capital outflow would increase, increasing the demand for loanable funds, as shown in the following figure. The result is a rise in U.S. interest rates, an increase in the quantity of U.S. saving (because of the higher interest rate), and lower U.S. domestic investment.b. In the market for foreign exchange, the real exchange rate declines and the balance of trade increases5. (15 points)a. When the stock market declines sharply, wealth declines, so the aggregate-demand curve shifts to the left, as shown in Figure 5a below. In the short run, the economy moves from point A to point B, as output declines and the price level declines. In the long run, the short-run aggregate-supply curve shifts to the right to restore equilibrium at point C, with unchanged output and a lower price level compared to point A.Figure 5aFigure 5bb. When the federal government increases spending on national defense, the rise in government purchases shifts the aggregate-demand curve to the right, as shown in Figure 5b above. In the short run, the economy moves from point A to point B, as output and the price level rise. In the long run, the short-run aggregate-supply curve shifts to the left to restore equilibrium at point C, with unchanged output and a higher price level compared to point A.c. When a technological improvement raises productivity, the long-run and short-run aggregate-supply curves shift to the right, as shown Figure 5c below. The economy moves from point A to point B, as output rises and the price level declines.Figure 5cd. When a recession overseas causes foreigners to buy fewer U.S. goods, net exports decline, so the aggregate-demand curve shifts to the left, as shown in Figure 5a above. The effects are similar with that in part a.e. The continuing increase in reserve ratio causes the decrease of money supply. So, the aggregate-demand curve shifts to the left, as shown in Figure 5a above. The effects are similar with that in part a..。

Because they have more risk thangovernment bonds and have no special tax treatment, they pay moderate ratesof return.58.First National Bank of MeAssets LiabilitiesReserves $800 Deposits $5,000Loans $4,20059.The costs of inflation include "shoeleather costs," the cost of reducing your money holdings to reduce your inflation tax; "menu costs," the costs of price adjustments; the costs of resource misallocation that result from the relative-price variability induced by inflation; the costs of inflation-induced tax distortions; the costs of confusion and inconvenience; and the costs associated with the arbitrary redistribution of wealth that accompany unexpected inflation.60.Examples in the text (or variations) include increased immigration, a decrease in the minimum wage, more generous unemployment insurance, an increase in the capital stock, an increase in the average level of education, a discovery of new mineral deposits, technology, and removal of barriers to international trade.61.See graph. Over time technological advances cause the long-run aggregate supply curve to shift right. Increases in the money supply cause the aggregate demand curve to shift right. Output growth puts downward pressure on the price level, but money supply growth contributes to rising prices.62.The wealth effect is not very important because it operates through changes in the real value of money, and money is only a small fraction of household wealth. So it is unlikely that changes in the price level will lead to large changes in consumption spending through this channel. The exchange-rate effect is not very important in the United States because trade with other countries represents a relatively small fraction of U.S. GDP.63. If the interest rate is above equilibrium, there is an excess supply of money. People with more money than they want to hold given the current interest rate deposit the money in banks and buy bonds. The increase in funds to lend out causes the interest rate to fall. As the interest rate falls, the quantity of money demanded increases, which tends to diminish the excess supply of money.64. a) 税收减少增加了储蓄的收益、减少了投资的成本,但税收减少对储蓄和投资的影响要视情况而定。

Write your answers on the answer sheet. While you are allowed to answer either in English or Chinese, it would be more graded at a reasonable degree if you choose to do it in English. Read the questions carefully before answering them. Be precise and keep tothe point.Good luck!Problem 1 (10 points)True or False? Explain your answer completely but briefly.a.(5 points) Consumption, investment, government purchases and net export are Notsources of Long-term economic growth.b.(2.5 points) It is one case of moral hazard that a patient is more likely to apply forhealth insurance than healthy men.c.(2.5pionts) According to the theory of efficiency wages, firms who pay wages atthe equilibrium level will operate more efficiently.Problem 2 (10 points)Suppose there is a small farming economy that produces corn. In such an economy, 80 bushels (蒲式耳) are consumed, 10 go for government purchases to feed the army, 6 go into domestic investment as increases in inventories, and 11 bushels are exported. In addition, the economy imports 7 bushels of corn and taxes farmers by 12 bushels.a.What is the GDP of the economy?b.Calculate private saving, public saving and net capital outflow. Then explain therelationship between saving and investment.c.Assuming in the economy, women have worked more hours in producing corn.How would this affect GDP? Explain the paradox, “When a person marries his or her gardener (园丁), GDP goes down.” Do you think GDP is a good measure of national accounts?Problem 3 (10 points)Below are some data about Pizza and Latte (拿铁,一种咖啡).pute the GDP deflator for each year, using 2006 as the base year.b.Suppose that the base year for the CPI is 2006. If the CPI basket consists of 400pieces of pizza and 1000 cups of latte during the three years, compute the CPI for each year. What is the CPI inflation rate from 2007 to 2008?c.According to your computation, what is the difference between GDP deflator andCPI?Problem 4 (15 points)The Federal Reserve conducts a $20 million open-market purchase of government bonds. The required reserve ratio is 10 percent.a.What is the money multiplier? How can this purchase affect money supply? Whatis the largest possible effect? What is the smallest possible effect? Explain why. b.Show the effects of this purchase in a diagram of money supply and moneydemand.c.Can you find roles of commercial banks and individual depositors in the creationof money in terms of multiplier formula?d.What happen to value of money and price level? And what is the impact of thismoney expansion on real variables such as output and employment?Problem 5 (10 points)Suppose Japanese decided they no longer wanted to buy U.S. assets as before. Using a three-panel diagram used in textbook for open economy, show the following effects of the change.a.What would happen in U.S. market for loanable funds? In particular, what wouldhappen to U.S. Interest rates, U.S. saving, and U.S. investment?b.What would happen in the market for foreign-currency exchange? In particular,what would happen to the value of the dollar and the U.S. trade balance?Problem 6 (15 points)Suppose that the economy is in a long-run equilibrium.e a diagram to illustrate the state of the economy. Be sure to show aggregatedemand, short-run aggregate supply, and long-run aggregate supply and explain why these curves look like this.b.Now suppose that a stock market crash causes aggregate demand to fall. Use yourdiagram to show what will happen to output and the price level in the short-run.What happen to the unemployment rate? And in the long run?c.Now suppose that a war in Middle East drives up the cost of producing oilproducts. What are the likely macroeconomic effects of such a change? Explain with the help of appropriate graphs.Problem 7 (15 points)a.Suppose the government increases its purchase expenditure by $20 billion, whichfinally raises the total demand for goods and services by $100 billion. If we ignore the possibility of crowding out, what would the marginal propensity to consume to be? If we allow for crowding out, would the marginal propensity to consume in this case be larger or smaller than their initial one?b.Suppose the government reduces taxes by $20 billion, there is no crowding out,and the MPC is 0.8. What is the initial effect of the tax reduction on aggregate demand? What is the total effect of this policy?c.How does the total effect of the $20 billion tax cut in part (b) compare to the totaleffect of a $20 billion increase in government purchase in part (a)? Why?Problem 8 (15 points)Suppose king's weather (好天气) drives down the cost of producing food products. a.Show the impact of such a change in both the aggregate-demand/aggregate-supplydiagram and in the Phillips-curve diagram. What happens to inflation andunemployment in the short-run?b.Do the effects of this event imply there is no short-run tradeoff between ininflation and unemployment? Why or why not?c.Suppose in the following year, bad weather brings stagflation, and the centralbank pursues contractionary (紧缩性的) monetary policy to reduce inflation. Use the Phillips curve to show the short-run and long-run effects of this policy. How might the short-run costs of the policy against inflation be reduced?武汉大学2008-2009学年第二学期期末考试经济与管理学院 2008级 2009年6月30日宏观经济学(A卷)Principles of Macroeconomics ( Paper A )说明:考试时间为2小时,满分为100分。
