下面的问题详细地分析教材中介绍的两部门内生增长模型。
a．用效率工人的人均产出和效率工人的人均资本重新求出制成品的生产函数。
b．在这个经济中，收支相抵的投资(保持效率工人人均资本量不变所需要的投资量)是多少？
c．求出k变动的公式，该公式表示△k是储蓄减收支相抵的投资。用这个式子画出一个表示稳定状态k的决定的图形。(提示：这个图看起来很像我们在分析索洛模型时所用过的图。)
d．在这个经济中，稳定状态的人均产出Y/L增长率是多少？储蓄率s和在大学中的劳动力比例u如何影响这一稳定状态增长率？
e．用你的图说明u的提高的影响。(提示：这种变动对两条曲线都产生影响。)
f．根据你的分析，u的提高对经济肯定是一件好事吗？并解释。
This question asks you to analyze in more detail the two-sector endogenous growth model presented in the text.
a．Rewrite the production function for manufactured goods in terms of output per effective worker and capital per effective worker.
b．In this economy, what is break-even investment (the amount of investment needed to keep capital per effective worker constant)？
c．Write down the equation of motion for k. which shows △k as saving minus break-even investment, Use this equation to draw a graph showing the determination of steady-state k. (Hint: This graph will look much like those we used to analyze the Solow model.)
d．In this economy, what is the steady-state growth rate of output per worker Y/L？ How do the saving rate s and the fraction of the labor force in universities u affect this steadystate growth rate？
e．Using your graph, show the impact of an increase in u. (Hint: This change affects both curves.) Describe both the immediate and the steady-state effects.
f．Based on your analysis, is an increase in u an unambiguously good thing for the economy？ Explain.

The term investment portfolio (证卷投资组合) conjures up visions of the truly rich--the Rockefellers, the WalMart Waltons, Bill Gates. But today, everyone--from the Philadelphia firefighter, his part-time receptionist wife and their three children, to the single Los Angeles lawyer, starting out on his own--needs a portfolio.
A portfolio is simply a collection of financial assets, it may include real estate, rare stamps and coins, precious metals and even artworks. But those are for people with expertise. What most of us need to know about arc stocks, bonds and cash (including such cash equivalents as money market funds).
How do you decide what part of your portfolio should go to each of the big three？ Begin by urulerstanding that stocks pay higher returns but are more risky; bonds and cash pay lower returns but are less risky.
Reach by Ibbotson Associates, for example, shows that large company stocks, on average, have returned 11.2 percent annually since 1926. Over the same period, by comparison, bonds have returned an annual average of 5.3 percent and cash, 3.8 percent.
But short term risk is another matter. In 1974, a one-year ＄1000 investment in the stock market would have declined to ＄735.
With bonds, there are two kinds of risk: that the borrower won't pay you back and that the money you'll get won't be worth very much. The U.S. government stands behind treasury bonds, so the credit risk is almost nil. But the inflation risk remains. Say you buy a ＄1000 bond maturing in ten years. If inflation averages about seven percent over that time, then the＄1000 you receive at maturity can only buy ＄500 worth of today's goods.
With cash, the inflation risk is lower, since over a long period you can keep rolling over your CDs every year (or more often). If inflation rises, interest rates rise to compensate.
As a result, the single most important rule in building a portfolio is this: If you don't need the money for a long time, then put it into stocks. If you need it soon, put it into bonds and cash.
This passage is intended to give 'advice on______.
A．how to avoid inflation risks
B．what kinds of bonds to buy
C．how to get rich by investing in stock market
D．how to become richer by spreading the risk

第10题
Choose two countries that interest you——one rich and one poor. What is the income per person in each country？ Find some data on country characteristics that might help explain the difference in income: investment rates, population growth rates, educational attainment, and so on. (Hint: The Web site of the World Bank,www.worldbank.org,is one place to find such data.) How might you figure out which of these factors is most responsible for the observed income difference？
