在习题1的基础上加入外国，其需求曲线为： D*= 80-20P，供给曲线为： S* =40+20P。
a.推导并绘出外国的出口供给曲线，同时计算没有贸易时外国的小麦价格。
b.如果本国和外国进行贸易，且运输成本为零。计算自由贸易时的均衡点，与之对应的世界价格是多少？贸易量又是多大？
Now add Foreign， which has a demand curve
D*=80-20P
and a supply curve
S*=40+20P
a. Derive and graph Foreign's export supply curve and find the price of wheat that would prevail in Foreign in the absence of trade.
b. Now allow Foreign and Home to trade with each other， at zero transportation cost. Find the equilibrium under free trade. What is the world price？ What is the volume of trade？
Sal's卫星公司向纽约和洛杉矶的订户发送电视节目。两地订户群体的需求曲线分别为:
(1)纽约市场和洛杉矶市场的利润最大化价格和数量各是多少？
(2)因为在五角大楼配置了一颗新卫星，洛杉矶人可以接收到Sal's在纽约发送的节目,而纽约人也可接收到Sal's在洛杉矶的播出。这样纽约或洛杉矶的任何人只要在任一城市付费就可收到Sal's的节目。因此Sal's只能定单一的价格。它会定什么价格，以及它在纽约和洛杉矶能销售多大数量呢？
(3)在上面的(1)还是(2)哪种情况下，Sal's是得益的？从消费者剩余的角度，纽约人偏爱哪种情况而洛杉矶人偏爱哪种情况？为什么？
Sal 's satellite company broadcasts TV to subscribers in Los Angeles and New York. The demand functions for each of these two groups are
a. i What are the profit - maximizing prices and quantities for the New York and Los Angeles markets？
b. As a consequence of a new satellite that the Pentagon recently deployed, people in Los Angeles receive Sal's New York broadcasts, and people in New York receive Sal's Los Angeles broad-casts. As a result, anyone in New York or los Angeles can receive Sal’s broadcasts by subscribing in either city. Hence Sal can charge only a single price. What price should he charge, and what quantities will he sell in New York and Los Angeles？
c.In which of the above situations. (a) or (b), is Sal better off？ In terms of consumer surplus, which situation do people in New York prefer and which do people in Los Angeles prefer？ Why？
A、$40million,100%4000万美元，100%
B、$100million,100%1亿美元，100%
C、$0million,29%0美元，29%
D、$40million,29%4000万美元，29%
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.
