第七章课后习题参考答案1。
汇率变化一定会产生营运风险吗?营运风险度量的是未曾预料到的汇率变动引起国际公司未来营运现金流量变化,从而导致公司净现值的改变。
如果是可预期的汇率变化则不会产生营运风险,因为公司管理层已充分考虑到可预期的汇率变化对公司未来的生产经营和市场价值的影响,公司编制的预算财务报表已经反映出了预期的汇率变化对公司价值的影响。
2。
营运风险的决定因素主要有哪些?(1)当地市场结构。
若国际公司在当地面临来自当地公司的竞争,则汇率变化会带来营运风险,若国际公司没有来自当地的竞争压力,而仅面临来自与自己同一个国家的公司的竞争,则汇率变化不会带来营运风险。
(2)调整市场结构和产品结构的能力.在给定的市场结构下,公司面临的营运风险取决于汇率变化时公司保持稳定现金流的能力。
(3)实际汇率变化的影响。
汇率的变化并不一定总是影响公司的竞争地位,当名义汇率变化恰好被通货膨胀率的变化所抵消时,汇率变化就不会带来营运风险.而当实际汇率发生变化时,营运风险将产生.3。
福特公司在墨西哥有一家销售公司,该公司从美国进口福特汽车,在墨西哥市场进行销售,而且福特汽车在墨西哥市场是富有需求弹性的。
如果美元相对于墨西哥比索升值,则:(1)如果墨西哥汽车市场主要由墨西哥国内汽车厂商所控制,则美元升值对福特在墨西哥公司的影响如何?(2)如果墨西哥汽车市场主要由来自美国如福特、通用等汽车厂商所控制,则美元升值对福特墨西哥销售公司影响如何?(1)当需求量变动百分数大于价格变动百分数,需求弹性系数大于1时,叫做需求富有弹性或高弹性.当美元升值时,该公司的进口成本增加,若相应地提高销售价格,则销量大幅度下降。
而其竞争对手墨西哥的汽车公司则不受影响。
此时,福特公司将面临营运风险,竞争力减弱。
(2)若福特汽车在墨西哥没有来自当地的竞争,仅面临其他美国汽车制造商的竞争,则福特的利润并不会减少,母公司也不会遭受营运风险。
因为其他美国公司在墨西哥的汽车同样受到美元升值的影响,市场份额不会发生较大的变化。

The Answers of Chapter 71. The difference between direct and indirect financing has to do with whether theborrower and lender seek each other out or whether an intermediary matchesborrowers and lenders. Direct financing requires no intermediary to matchsavers and borrowers. An economy will benefit from having both direct andindirect financing because both are appropriate ways to save and invest underdifferent circumstances. As discussed in the text, financial intermediaries absorba fraction of each saver's dollar that is borrowed. Thus, the intermediary takessome of the funds that otherwise would have gone to a borrower. However, the financial intermediary provides an important service by reducing informationasymmetries, allowing savers to pool risk, and matching risk and return.Therefore, when an individual cannot research these issues on his/her own, the intermediary is necessary to help the financial markets operate. However, astrong bond market, in which borrowers and savers can directly interact, allows for informed parties to save the funds that otherwise would go to an intermediary.This, in turn, uses the savings more efficiently.2. Portfolio flows are relatively short term in nature (have a shorter term to maturity),involve lower borrowing costs, and can generate near-term income. They also do not require a firm to give up control to a foreign investor. Consequently, they may help to improve capital allocation within an economy and help the economy's financial sector develop. These are all potential benefits of portfolio investments.By the same token, however, they are also relatively easy to reverse in direction, which is a potential disadvantage of portfolio investment.On the other hand, foreign direct investment (FDI) involve some degree ofownership and control of a foreign firm, are typically long term in nature, and help provide a stabilizing influence on a nation's economy. As such, FDI is typically more difficult to arrange.It is not advantageous to rely on either type of investment exclusively, in so far as each type accomplishes different goals for an economy. Both near-andlong-term capital are important for an economy's growth.3. As either portfolio investment of FDI increase, the demand for the local currencyrises (e.g., there is a shift from D0 to D1), which puts upward pressure on the value of the currency, from S0 to S1. If the central bank expects to hold the value of the currency constant at S0, it will have to increase the quantity of the domesticcurrency supplied (e.g., accommodate the excess quantity demanded at the initial spot rate S0) to maintain the peg. The opposite would hold for capital outflows.4. Suppose that a multinational bank (MNB) headquartered in a developed economyenters a developing economy. The MNB has gained considerable expertise in working as a financial intermediary, and likely has achieved economies of scale in doing so. By entering a foreign market, it helps to allocate the savings more efficiently through its intermediation services; which in turn will lead to additional economic development. Specifically, it should help to make sure that the best investment projects are funded. Moreover, the competition it introduces into the capital market helps to improve the quality of the indigenous financialintermediaries. This, in turn, should also add to financial stability.5. Savers and borrowers can also benefit from the regulation of financialintermediaries when portfolio capital flows dominate a country's capital inflows.It can be argued that regulation to limit short-term inflows can stabilize theeconomy and that these regulations can be gradually lifted as the economybecomes more stable (financial markets develop) and resilient to external shocks.These regulations do impose costs in that they require resources to enforce, and may inhibit otherwise helpful capital inflows which may aid economicdevelopment. However, these costs must be considered against the potential losses that may be incurred if the absence of capital controls would lead to more volatile and capital markets (which may deter the inflow of foreign capital).6. Policymakers should undertake actions that attract both portfolio capital flows andFDI flows. Actions that improve transparency in both the private a public sector reduces information asymmetries and their associate problems thereby making portfolio flows more stable, in other words, reducing the risk of massive capital outflows. Policymakers may also undertake actions that promote education,improve the tax structure and tax collection, and improve the countriesinfrastructure. These actions may, in turn, attract FDI.7. In the following two examples it is assumed that the policymaker maintains apegged-exchange rate regime and does not opt for a floating-rate regime. Hence, the policymaker may either intervene and maintain the peg or change the value of the peg. In both cases there is pressure for the domestic currency to appreciate visa vis the foreign currency.a. If the exchange rate pressure is only temporary in nature, then the policymakermay intervene by accommodating the excess quantity demanded, as explained in question 3 above.b. Because the exchange rate pressure is longer-term in nature, the policymakerwould be well advised to revalue the domestic currency.8. The World Bank was initially established to help countries rebuild after WWIIand in the 1960s expanded to also make long term loans to developing nations in order to help reduce poverty and improve living standards. Recently, some of the World Bank's activities have begun to overlap the IMF's activities to finance long-term structural adjustments and provide refinancing for some heavilyindebted countries. Critics may argue that the tasks that are duplicated by the IMF and the World Bank create conflicting goals for the World Bank. Thus, the two organizations may each benefit by focusing on different aims. For instance, the IMF may return to financing shorter-term objectives and leave the World Bank to worry about longer-term projects.Another conflicting line of reasoning involves donors' expectation that the World Bank maintain a revenue stream form its projects. This can be argues asunrealistic, however, in that the poorest countries are less likely to yield a payoff for the needed projects; and these are precisely the countries that the World Bank is designed and intended to help. On the other hand, the less risky projects,which could provide a positive revenue stream are likely to attract private capital.9. The first cause of a crisis could be an imbalance in the economy. In other words,an incongruity in economic fundamentals could cause a crisis. Possibleindicators include theoretical divergences between various economic variables such as the exchange rate and interest rates, income, and money supply. In terms of evaluation, if fundamental economic variables seem to be out of line, there may be an impending crisis.A second cause is that of self-fulfilling expectations and contagion effects. Inthis case, mere expectations of a potential inability to maintain a specifiedexchange rate or a slight incongruity between economic conditions and the market exchange rate may cause a cascade of speculation that leads to a crisis. Since this is based on perception, it is difficult to find an indicator. One possibleindicator would be trading volumes of currency for countries that may be at risk from the viewpoint of economic fundamentals. If trading volumes grew quickly,a crisis may be on the horizon.Finally, the structural moral hazard problem may indicate a crisis. In this case, a credit rating bureau, such as Moody's may provide the data needed to indicate a potential crisis. The quality of the credit rating would be relatively easilyinterpreted to indicate a potential crisis.10.Answers will vary. A potential strength of this proposal would be the centralized,and assumedly unified, efforts to stabilize the global economic environment. If it works, the global economy would be more stable. A potential weakness involves the question of how practical this proposal would be, and how easy it would be to match individual countries' domestic policy goals with the organization's global goals and economic interventions. A potential of conflict between theorganization's interventions and national interests could be a significant weakness.11. It can be argued that such below market interest rate loans are critical for adeveloping nation's economy in order for the economy to grow unburdened by high interest payments when it is trying to funnel profits back into the economy and sustain growth. Conversely, providing these non-market rate loans can also be argued to distort the market for loanable funds and attract inefficientinvestment. Students' perspectives will vary as to which argument is the best.。
Problems and Applications1.If an early freeze in California sours the lemon crop, the supply curve for lemons shiftsto the left, as shown in Figure 7-5.The result is a rise in the price of lemons and adecline in consumer surplus from A + B + C to just A. So consumer surplus declines by the amount B + C.Figure 7-5In the market for lemonade, the higher cost of lemons reduces the supply of lemonade,as shown in Figure 7-6.The result is a rise in the price of lemonade and a decline inconsumer surplus from D + E + F to just D, a loss of E + F. Note that an event that affectsconsumer surplus in one market often has effects on consumer surplus in other markets.Figure 7-62. A rise in the demand for French bread leads to an increase in producer surplus in themarket for French bread, as shown in Figure 7-7.The shift of the demand curve leads to an increased price, which increases producer surplus from area A to area A + B + C.Figure 7-7The increased quantity of French bread being sold increases the demand for flour, asshown in Figure 7-8.As a result, the price of flour rises, increasing producer surplusfrom area D to D + E + F. Note that an event that affects producer surplus in onemarket leads to effects on producer surplus in related markets.Figure 7-83. a.Bert’ s demand schedule is:Price Quantity DemandedMore than $7 0$5 to $7 1$3 to $5 2$1 to $3 3$1 or less 4Bert’ s demand curve is shown in Figure 7 -9.Figure 7-9b.When the price of a bottle of water is $4, Bert buys two bottles of water.Hisconsumer surplus is shown as area A in the figure.He values his first bottle ofwater at $7, but pays only $4 for it, so has consumer surplus of $3.He valueshis second bottle of water at $5, but pays only $4 for it, so has consumersurplus of $1.Thus Bert’ s total consumer surplus is $3 + $1 = $4, which isthe area of A in the figure.c.When the price of a bottle of water falls from $4 to $2, Bert buys three bottlesof water, an increase of one. His consumer surplus consists of both areas Aand B in the figure, an increase in the amount of area B. He gets consumersurplus of $5 from the first bottle ($7 value minus $2 price), $3 from thesecond bottle ($5 value minus $2 price), and $1 from the third bottle ($3 valueminus $2 price), for a total consumer surplus of $9. Thus consumer surplusrises by $5 (which is the size of area B) when the price of a bottle of water fallsfrom $4 to $2.4. a. Ernie ’ s supply schedule for water is:Price Quantity SuppliedMore than $7 4$5 to $7 3$3 to $5 2$1 to $3 1Less than $1 0Ernie’ s supply curve is shown in Figure 7 -10.Figure 7-10b.When the price of a bottle of water is $4, Ernie sells two bottles of water.Hisproducer surplus is shown as area A in the figure.He receives $4 for his firstbottle of water, but it costs only $1 to produce, so Ernie has producer surplusof $3.He also receives $4 for his second bottle of water, which costs $3 toproduce, so he has producer surplus of$1. Thus Ernie’ s total producersurplus is $3 + $1 = $4, which is the area of A in the figure.c.When the price of a bottle of water rises from $4 to $6, Ernie sells three bottlesof water, an increase of one.His producer surplus consists of both areas Aand B in the figure, an increase by the amount of area B.He gets producersurplus of $5 from the first bottle ($6 price minus $1 cost), $3 from the secondbottle ($6 price minus $3 cost), and $1 from the third bottle ($6 price minus $5price), for a total producer surplus of $9.Thus producer surplus rises by $5(which is the size of area B) when the price of a bottle of water rises from $4to $6.5. a. From Ernie ’ s supply schedule and Bert ’ s demand schedule, the quantitydemanded and supplied are:Price Quantity Supplied Quantity Demanded$ 2 1 34 2 26 3 1Only a price of $4 brings supply and demand into equilibrium, withan equilibrium quantity of 2.b.At a price of $4, consumer surplus is $4 and producer surplus is $4, as shownin problems 3 and 4.Total surplus is $4 + $4 = $8.c.If Ernie produced one fewer bottle, his producer surplus would decline to $3,as shown in problem 4.If Bert consumed one fewer bottle, his consumersurplus would decline to $3, as shown in problem 3. So total surplus would declineto $3 + $3 = $6.d.If Ernie produced one additional bottle of water, his cost would be $5, but theprice is only $4, so his producer surplus would decline by $1.If Bertconsumed one additional bottle of water, his value would be $3, but the priceis $4, so his consumer surplus would decline by $1.So total surplus declinesby $1 + $1 = $2.6. a.The effect of falling production costs in the market for stereos results in a shiftto the right in the supply curve, as shown in Figure 7-11.As a result, theequilibrium price of stereos declines and the equilibrium quantity increases.b.The decline in the price of stereos increases consumer surplus from area A to A+ B + C + D, an increase in the amount B + C + D.Prior to the shift in supply,producer surplus was areas B + E (the area above the supply curve and belowthe price).After the shift in supply, producer surplus is areas E + F + G.Soproducer surplus changes by the amount F + G - B, which may be positive ornegative.The increase in quantity increases producer surplus, while thedecline in the price reduces producer surplus.Since consumer surplus risesby B + C + D and producer surplus rises by F + G - B, total surplus rises by C+ D+F+G.c.If the supply of stereos is very elastic, then the shift of the supply curvebenefits consumers most.To take the most dramatic case, suppose thesupply curve were horizontal, as shown in Figure 7-12.Then there is noproducer surplus at all.Consumers capture all the benefits of fallingproduction costs, with consumer surplus rising from area A to area A + B.Figure 7-11Figure 7-127. Figure 7-13 shows supply and demand curves for haircuts. Supply equals demand ata quantity of three haircuts and a price between $4 and $5. Firms A, C, and D shouldcut the hair of Sally Jessy, Jerry, and Montel. Oprah ’ s willingness to pay is too low and firm B ’ s costs are too high, so they do not participate. The maximum total surplus isthe area between the demand and supply curves, which totals $11 ($8 value minus$2 cost for the first haircut, plus $7 value minus $3 cost for the second, plus $5 valueminus $4 cost for the third).Figure 7-138. a.The effect of falling production costs in the market for computers results in ashift to the right in the supply curve, as shown in Figure 7-14.As a result, theequilibrium price of computers declines and the equilibrium quantity increases.The decline in the price of computers increases consumer surplus from area Ato A + B + C + D, an increase in the amount B + C + D.Figure 7-14Prior to the shift in supply, producer surplus was areas B + E (the area abovethe supply curve and below the price).After the shift in supply, producersurplus is areas E + F + G.So producer surplus changes by the amount F + G- B, which may be positive or negative.The increase in quantity increasesproducer surplus, while the decline in the price reduces producer surplus. Sinceconsumer surplus rises by B + C + D and producer surplus rises by F + G - B,total surplus rises by C + D + F + G.——Figure 7-15b.Since adding machines are substitutes for computers, the decline in the priceof computers means that people substitute computers for adding machines,shifting the demand for adding machines to the left, as shown in Figure 7-15.The result is a decline in both the equilibrium price and equilibrium quantity ofadding machines.Consumer surplus in the adding-machine market changesfrom area A + B to A + C, a net gain of C - B.Producer surplus changes fromarea C + D + E to area E, a net loss of C + D.Adding machine producers aresad about technological advance in computers because their producersurplus declines.c.Since software and computers are complements, the decline in the price andincrease in the quantity of computers means that people’ s demand forsoftware increases, shifting the demand for software to the right, as shown inFigure 7-16. The result is an increase in both the price and quantity of software.Consumer surplus in the software market changes from B + C to A+B, a net increase of A - C. Producer surplus changes from E to C + D + E, anincrease of C + D, so software producers should be happy about the technologicalprogress in computers.d.Yes, this analysis helps explain why Bill Gates is one the world’ s richest msince his company produces a lot of software that’ s a complement withcomputers and there has been tremendous technological advance incomputers.——Figure 7-169. a. Figure 7-17 illustrates the demand for medical care. If each procedure has aprice of $100, quantity demanded will be Q 1 procedures.Figure 7-17b.If consumers pay only $20 per procedure, the quantity demanded will be Q 2procedures.Since the cost to society is $100, the number of proceduresperformed is too large to maximize total surplus.The quantity thatmaximizes total surplus is Q 1 procedures, which is less than Q2.c.The use of medical care is excessive in the sense that consumers getprocedures whose value is less than the cost of producing them.As a result,——the economy’ s total surplus is reduced.d.To prevent this excessive use, the consumer must bear the marginal cost ofthe procedure.But this would require eliminating insurance.Anotherpossibility would be that the insurance company, which pays most of themarginal cost of the procedure ($80, in this case) could decide whether theprocedure should be performed.But the insurance company doesn’ t get thebenefits of the procedure, so its decisions may not reflect the value to theconsumer.10. a. Figure 7-18 illustrates the effect of the drought. The supply curve shifts tothe left, leading to a rise in the equilibrium price from P 1 to P 2 and a decline inthe equilibrium quantity from Q 1 to Q 2 .Figure 7-18b.If the price of water is not allowed to change, there will be an excess demandfor water, with the shortage shown on the figure as the difference between Q 1and Q 3 .c.The system for allocating water is inefficient because it no longer allocateswater to those who value it most highly.Some people who value water atmore than its cost of production will be unable to obtain it, so societysurplus isn’ t maximized.The allocation system seems unfair as well.Water is allocated simply on pastusage, rewarding past wastefulness.If a family’ s demand for water increases,——say because of an increase in family size, the policy doesn ’ t allow them to obtain more water. Poor families, who probably used water mostly fornecessary uses like drinking, would suffer more than wealthier families whowould have to cut back only on luxury uses of water like operating backyardfountains and pools. However, the policy also keeps the price of water lower,which benefits poor families, since otherwise more of their family budgetwould have to go for water.d. If the city allowed the price of water to rise to its equilibrium price P 2 , theallocation would be more efficient. Quantity supplied would equal quantitydemanded and there would be no shortage. Total surplus would bemaximized.Whether the market allocation would be more or less fair than theproportionate reduction in water under the old policy is difficult to say, but it islikely to be more fair. Notice that the quantity supplied would be higher (Q 2)in this case than under the water restrictions (Q 3 ), so there ’ s less reduction inwater usage. To make the market solution even more fair, the governmentcould provide increased tax relief or welfare payments for poor families whosuffer from paying the higher water prices.。
第7章货币需求本章思考题1.什么是货币需求和货币需求理论?答:(1)所谓货币需求,它是指在一定时期内,社会各阶层(个人、企业单位、政府)愿以货币形式持有财产的需要,或社会各阶层对执行流通手段、支付手段和价值贮藏手段的货币的需求。
从货币需求的定义可以看出,不能将货币需求仅理解为一种主观欲望、一种纯心理的占有欲望。
人们产生对货币需求的根本原因在于货币所具有的职能。
货币需求主要是一个宏观经济学问题。
货币需求与货币供给直接对应,研究货币供给,不能超越货币需求这一范畴。
(2)货币需求理论是一种关于对货币需求的动机影响因素和数量决定的理论,是货币政策选择的理论出发点。
货币需求理论所研究的内容是一国经济发展在客观上需要多少货币量,货币需要量由哪些因素组成,这些因素相互之间有何关系,以及一个经济单位(企业、家庭或个人)在现实的收入水平、利率和商品供求等经济背景下,手中保持多少货币的机会成本最小、收益最大等问题。
2.试述货币需求和资金需求的关系,并弄清这一关系的实际意义。
答:(1)要弄清货币需求和资金需求的关系,首先要弄清货币和资金这两个概念的异同。
货币应是包括现金和存款在内的“大货币”,货币需求也应是所有为商品、劳务流通服务以及有关一切货币支付所提出的货币需求。
资金是指在社会再生产过程中,不断占用和周转的、有特定目的和用途的、可以增殖的一定价值量。
从资金的含义看,其与“资本”这一概念没有多大差别。
(2)货币和资金是有明显区别的,主要表现在:①存在形态不同。
货币只能存在于货币形态;而资金不仅可存在于货币形态,还可以存在于实物形态。
②运动过程不同。
货币运动的程序是“商品(W)—货币(G)—商品(W)”,货币在这里作为商品交换的媒介;而资金运动程序是“G—W…P…W′—G′”,这里的P是指生产过程即价值的增殖过程。
③需要量的规律不同。
货币需要量公式为M=PT/V;而资金需要量则等于产品生产总值除以资金周转次数。
④货币资金具有双重性。
1.答案可以不一样.答案示例:共产主义制度与亚当斯密的看不见得手是完全相反的.但是最近我们已经注意到了世界范围内许多共产主义国家的失败.在共产主义国家里,据信政府可以做出与私人相比更好的决策去推动经济的繁荣.但是很明显,这种制度没能推动经济的繁荣.亚当斯密认为,完全竞争的市场体制(而不是政府) 一般而言可以更好得配置资源从而推动经济的繁荣.但是,一个完全没有束缚的资本主义社会比如18世纪晚期的西方世界国家可能并不是一个完美的体制.看不见的手使富人更富同时穷人却得不到任何正式的帮助,于是政府计划最终建立了起来促进社会福利和公平.2.在资本主义社会,价格机制有利于做出正确的资源配置决策.资本流向那些能利用它获得最高回报率的部门.从而这样把资本分配到生产率最高的用处,借以增进社会经济的繁荣.而且,金融体系有自己的市场和调解机构,它们可以把风险从最不愿意承担的人那里转移到最愿意承担风险的人那里.一般而言,这将使社会受益而不会有任何的代价.并且,通过允许私人减少或者消除风险,可以形成一个承担商业冒险的社会氛围,这将使社会受益.3.清算和支付:在亚当斯密的时代,正如现在一样有纸币和硬币.但是,由于技术革新(主要是电脑技术的应用与发展)现在有许多其它不同形式的支付手段,例如个人支票,信用卡,资金的借方卡以及电子转帐.而且,某些信用卡和旅行支票在世界上的任何地方都可以被受理,使货币兑换成为过去的一种遗留物.聚集资源和分散股权:在亚当斯密的时代,大部分商业贸易规模都很小,并且由独资企业投资.因此,聚集资源进行大规模投资的需求不像今天这样普遍和重要.而且,电脑和电话技术的革命把全球的资本市场联系起来为更大规模的贸易融资.今天这些公司能进入全世界范围巨大的资产并且找到为大规模工程投资的最便宜的资源转移经济资源:在当代,世界范围内的金融体系使资源和风险及时的从一个人转移到另一个人,从一个地方转移到另一个地方变得更加容易.而在亚当斯密的时代,尽管有金融市场,但是作用有限, 与今天的相比它们都是区域性的,规模小,缺乏效率和创新.风险管理:在亚当斯密的时代,私人和商业都会面对许多与今天相同的风险(财产损毁的风险,金融损失的风险,粮食歉收风险等等)但是,过去只有有限的方法去化解风险.那时虽然有一些保险公司,但主要是管理商业风险而非个人风险,因此也就没有同类型保险去管理个人风险.比如,失业保险.在亚当斯密的时代,农场主几乎没有办法去降低粮食歉收以及粮食价格降低的风险.现在有大量的市场和部门去化解个人及商业风险,还有大量的网络保险公司去把风险从那些想减少的人那里转移到那些想承担更多风险的人那里.价格信息:在亚当斯密的时代,信息传播的速度很慢.当然,那时没有电话,电视和收音机等工具.信息只能通过报纸和信件进行传播.现在,信息可以在世界范围内及时传播.由于电脑和电话技术的发展和创新,安全的价格信息同时在世界范围内通过各种虚拟的途径获得.激励问题:正如上面所讨论的,当代的金融体系是大规模,创新和全球性的.在亚当斯密的时代,如果出现道德风险和逆向选择问题就没有像今天这样高效的金融体系去处理.4. 亚当斯密谈论的自由竞争市场作为一个完整的体系可以把资本分配到使用效率最高和最有价值的地方.在一个自由竞争的股票市场,股票的价格是由供给和需求决定的.那些得到最高回报的公司将会得到最高的价格(或者是最便宜的金融资本).而一些公司将得不到足够的资本因为他们是没有效率的.由于世界范围内的合意投资是巨大的以及有时对于投资者而言很难识别哪个公司是资本最有效率的雇佣者,因此规则应该被制定出来以保证相关的和合乎标准的信息传递给潜在的投资者.这将包括公开和内部的交易以及股票操作方面的规则.但是从市场效率方面而言,一些其它形式的市场规则可能就不是那末重要甚至将有碍整个社会福利的实现.5. 由于大部分学生现在还不能挣钱,也没有积蓄或其它的资本,所以没有哪个中间人会在任何合意的利率水平上承担这样的信用风险.6例如:医药公司;儿童安全设备生产公司;航空公司;银行;医院;环保咨询公司;危险性垃圾处理公司7 我用自己的钱投资的20000美元是(企业主的)股本,其他的80000美元是负债。
第七章互换的定价与风险分析7.1复习笔记互换既可以分解为债券的组合,也可以分解为一系列远期协议的组合。
根据这一思路就可以对互换进行定价。
根据国际市场上的惯例,在给互换和其他柜台交易市场上的金融工具定价时,现金流通常用LIBOR贴现。
这是因为LIBOR反映了金融机构的资金成本。
一、利率互换的定价1.利率互换定价的基本原理(1)互换的本质,即未来系列现金流的组合。
(2)对一方而言,利率互换可以看做一个浮动利率债券多头与固定利率空头头寸的组合,这个利率互换的价值就是浮动利率债券与固定利率债券价值的差。
由于互换为零和游戏,对于另一方而言,该利率互换的价值就是固定利率债券价值与浮动利率债券价值的差。
也就是说,利率互换可以通过分解成一个债券的多头与另一个债券的空头来定价。
(3)利率互换可以看成是一系列用固定利率交换浮动利率的FRA的组合。
只要知道组成利率互换的每笔FRA的价值,就可以计算出利率互换的价值。
具体来看,与远期合约相似,利率互换的定价有两种情形:第一,在协议签订后的互换定价,是根据协议内容与市场利率水平确定利率互换合约的价值。
对于利率互换协议的持有者来说,该价值可能是正的,也可能是负的。
第二,在协议签订时,一个公平的利率互换协议应使得双方的互换价值相等。
也就是说,协议签订时的互换定价,就是选择一个使得互换的初始价值为零的固定利率。
2.协议签订后的利率互换定价(1)运用债券组合给利率互换定价定义:B fix为互换合约中分解出的固定利率债券的价值。
B fl为互换合约中分解出的浮动利率债券的价值。
对于互换多头,也就是固定利率的支付者来说,利率互换的价信就是(7.1)反之,对于互换空头,也就是浮动利率的支付者来说,利率互换的价值就是(7.2)这里固定利率债券的定价公式为(7.3)其中,A为利率互换中的名义本金额,k为现金流交换日交换的固定利息额,n为交换次数,t i为距第i次现金流交换的时间长度(1≤i≤n),r i&则为到期日为t i的LIBOR连续复利即期利率。
⾦融学原理英⽂第七单元课后答案CHAPTER 7ANSWERS7-1 The four financial statements contained in most annual reports are the balance sheet, income statement, statement of retained earnings, andstatement of cash flows.7-2 No, because the $20 million of retained earnings probably would not be held as cash. The retained earnings figure represents the reinvestmentof earnings by the firm. Consequently, the $20 million would be aninvestment in all of the assets of the firm.7-3 Liquidating assets, borrowing more funds, and issuing stock would constitute sources of funds. Purchasing assets, paying off debt, and stockrepurchases would constitute uses of funds. Thus, the following general rules can be used to determine what changes in balance sheet accountsrepresent sources and uses of funds:Sources of cash: Uses of Cash:in a liability or equity account in a liability of equity accountin an asset account in an asset account7-4 The emphasis of the various types of analysts is by no means uniform nor should it be. Management is interested in all types of ratios for two reasons.First, the ratios point out weaknesses that should be strengthened; second,management recognizes that the other parties are interested in all theratios and that financial appearances must be kept up if the firm is tobe regarded highly by creditors and equity investors. Equity investorsare interested primarily in profitability, but they examine the otherratios to get information on the riskiness of equity commitments. Long-term creditors are more interested in the debt ratio, TIE, and fixed chargecoverage ratios, as well as the profitability ratios. Short-term creditorsemphasize liquidity and look most carefully at the liquidity ratios.7-5 The most important aspect of ratio analysis is the judgment used when interpreting the results to reach an overall conclusion concerning a firm'sfinancial position. The analyst should be aware of, and include in theinterpretation, the fact that: (1) large firms with many differentdivisions are difficult to categorize in a single industry; (2) financialstatements are reported at historical costs; (3) seasonal factors candistort the ratios; (4) some firms try to "window dress" their financial statements to look good; (5) firms use different accounting procedures to compute inventory values, depreciation, and so on; (6) there might notexist a single value that can be used for comparing firms' ratios (e.g.,a current ratio of 2.0 might not be good); and (7) conclusions concerningthe overall financial position of a firm should be based on a representativenumber of ratios, not a single ratio.7-6 Differences in the amounts of assets necessary to generate a dollar of sales cause asset turnover ratios to vary among industries. For example,a steel company needs a greater number of dollars in assets to producea dollar in sales than does a grocery store chain such as Safeway. Also,profit margins and turnover ratios might vary due to differences in theamount of expenses incurred to produce sales. For example, one would expecta grocery store chain like Safeway to spend more per dollar of sales thandoes a steel company. Often, a large turnover will be associated with a low profit margin, and vice versa.7-7 ROE can be writtenTotal assets divided by owners' equity, which is termed the equity multiplier, is a measure of debt utilization; the more debt, the higher the equity multiplier. Thus, using more debt will increase the equity multiplier, resulting in a higher ROE.7-8 a. Cash, receivables, and inventories, as well as current liabilities, vary over the year for firms with seasonal sales patterns. Therefore,those ratios that examine balance sheet figures will vary unlessaverages (monthly ones are best) are used.b. Common equity is determined at a point in time, say, December 31, 2002.Profits are earned over time, say, during 2002. If a firm is growing rapidly, year-end equity will be much larger than beginning-of-year equity, so the calculated rate of return on equity will be different depending on whether end-of-year, beginning-of-year, or average common equity is used as the denominator. Average common equity is conceptually the best figure to use.In public utility rate cases, people are reported to have deliberately used end-of-year or beginning-of-year equity to make returns on equity appear exces-sive or inadequate. Similar problems can arise when a firm is being evaluated.7-9 Source(+)2002 2001 or Use(-)?Cash $ 400 $ 500 +Accounts receivable 250 300 +Inventory 450 400 -Current assets 1,100 1,200Net property & equipment 1,000 950 -aTotal assets $2,100 $2,150Accounts payable $ 200 $ 400 -Accruals 300 250 +Notes payable 400 200 +Current liabilities 900 850Long-term debt 800 900 - Total liabilities 1,700 1,750Common stock 250 300 -Retained earnings 150 100 +bTotal liabilities $2,100 $2,150and equitya The book value of property & equipment is stated net of depreciation.Because the book value of fixed assets increased, and depreciation is an adjustment that reduces the account balance, Batelan must have purchased additional fixed assets; but, without more information we cannot determine the amount of the purchase.b The retained earning balance increased in 2002, so Batelan must havegenerated a positive net income.

It would be helpful to know the future plans Argile has with respect to improving its currentfinancial position, introducing new products, liquidating unprofitable investments, and so on. Perhaps the fixed assets turnover ratio and return on assets figures are low because the firm has expanded its product distribution, and this process has a large cost "up front" with significant payoffs beginning in two or three years.7-2 a.60.0%61.90% 500,947$500,586$assets Total debt Total 9.0%7.56% 000,361$300,27$equity Common income Net 3.6%2.88% 500,947$300,27$assets Total income Net 1.2%1.70% 500,607,1$300,27$Sales income Net 3.0 1.70 500,947$500,607,1$assets Total Sales 5.6 5.60 500,241$000,353,1$s Inventorie sold goods of Cost days35.0 days 24.75 28.465,4$000,336$360/Sales receivable Accounts 2.0 98.1 000,330$000,655$s liabilitie Current assets Current Average Campsey Industry ========?========b.For Campsey, ROA = PM ? TA turnover = 1.7% ? 1.7 = 2.89%.For the industry, ROA = 1.2% ? 3.0 = 3.6%.c.Campsey's days sales outstanding is more than twice as long as the industry average, indicating that the firm should tighten credit or enforce a more stringent collection policy. The total assets turnover ratio is well below the industry average so sales should be increased, assets decreased, or both. While Campsey's profit margin is higher than the industry average, its other profitability ratios are low compared to the industry--net income should be higher given the amount of equity and assets. However, the company seems to be in an average liquidity position and financial leverage is similar to others in the industry. d.If 2002 represents a period of supernormal growth for Campsey, ratios based on this year will be distorted and a comparison between them and industry averages will have little meaning.

Poor Return on total assets 6.0%9.0% Poorc. Analysis of the Du Pont equation and the set of ratios shows that the turnover ratio of sales toassets is quite low. Either sales should be increased at the present level of assets, or the current level of assets should be decreased to be more in line with current sales. Thus, the problem appears to be in the balance sheet accounts.d. The comparison of inventory turnover ratios shows that other firms in the industry seem to begetting along with about half as much inventory per unit of sales as Finnerty. If Finnerty's inventory could be reduced this would generate funds that could be used to retire debt, thus reducing interest charges and improving profits, and strengthening the debt position. There might also be some excess investment in fixed assets, perhaps indicative of excess capacity, as shown by a slightly lower than average fixed assets turnover ratio. However, this is not nearly as clear-cut as the over-investment in inventory.e. If Finnerty had a sharp seasonal sales pattern, or if it grew rapidly during the year, many ratiosmight be distorted. Ratios involving cash, receivables, inventories, and current liabilities, as well as those based on sales, profits, and common equity, could be biased. It is possible to correct for such problems by using average rather than end-of-period figures.7-5 a.

Poor M/B ratio 0.65 n.a. --Cary appears to be badly managed--all of its ratios are worse than the industry averages, and the result is low earnings, a low P/E, a low stock price, and a low M/B ratio. The company needs to do something to improve.b.A decrease in the inventory level would improve the inventory turnover, total assets turnover, and ROA, all of which are too low. It would have some impact on the current ratio, but it is difficult to say precisely how that ratio would be affected. If the lower inventory level allowed Cary to reduce its current liabilities, then the current ratio would improve. The lower cost of goods sold would improve all of the profitability ratios and, if dividends were not increased, would lower the debt ratio through increased retained earnings. All of this should lead to a higher market/book7-6We are given ROA = 3% and Sales/Total assets = 1.5?.From Du Pont equation: ROA = Profit margin ? Total assets turnover 3% = Profit margin (1.5) Profit margin = 3%/1.5 = 2%.We can also calculate Zumwalt's debt ratio in a similar manner, given the facts of the problem. We aregiven ROA, which is NI/A and ROE, which is NI/Equity; if we use the reciprocal of ROE we have the following equation: Debt/Assets = 1 - Equity/A = 1 - 0.60 = 0.40 = 40.0%Thus, Zumwalt's net profit margin = 2% and its debt ratio = 40%.7-7 Present current ratio = $1,312,500/$525,000 = 2.5Minimum current ratio = $1,312,500 + NP$525,000 + NP ?? = 2.0$1,312,500 + ΔNP = $1,050,000 + 2ΔNPΔNP = $262,500.Short-term debt can increase by a maximum of $262,500 without violating a 2-to-1 current ratio, assuming that the entire increase in notes payable is used to increase current assets. Because we assumed that the additional funds would be used to increase inventory, the inventory account will increase to $637,500, and current assets will total $1,575,000.Quick ratio = ($1,575,000 ─ $637,500)/$787,500 = $937,500/$787,500 = 1.19? 7-8 (1)Current liabilities = $270,000.

Currently, ROE is ROE1 = $15,000/$200,000 = 7.5%.The current ratio will be set such that 2.5 = CA/CL. CL is $50,000, and it will not change, so we can solve to find the new level of current assets: CA = 2.5(CL) = 2.5($50,000) = $125,000. Thisis the level of current assets that will produce a current ratio of 2.5?.At present, current assets amount to $210,000, so they can be reduced by $210,000 ─ $125,000 = $85,000.If the $85,000 generated is used to retire common equity, then the new common equity balance will be $200,000 ─ $85,000 = $115,000.Assuming that net income is unchanged, the new ROE will be ROE2 = $15,000/$115,000 =13.04%. Therefore, ROE will increase by 13.04% ─ 7.50% = 5.54%.b. (1) Doubling the dollar amounts would not affect the answer; the ROE increase would still be5.54%.(2) Current assets would increase by $25,000, which would mean a new ROE of$15,000/$140,000 = 10.71%, which would mean a difference of 10.71% ─7.50% =3.21%.(3)If the company had 10,000 shares outstanding, then its EPS would be $15,000/10,000 = $1.50. The stock has a book value of $200,000/10,000 = $20, so the shares retiredwould be $85,000/$20 = 4,250, leaving 10,000 ─ 4,250 = 5,750 shares. The new EPSwould be $15,000/5,750 = $2.6087, so the increase in EPS would be $2.6087 ─ $1.50 =$1.1087, which is a 73.91% increase, the same as the increase in ROE.(4)If the stock was selling for twice book value, or 2 ? $20 = $40, then only half as manyshares could be retired ($85,000/$40 = 2,125), so the remaining shares would be 10,000─ 2,125 = 7,875, and the new EPS would be $15,000/7,875 = $1.9048, for an increase of$1.9048 ─ $1.5000 = $0.4048.c. We could have started with lower inventories and higher accounts receivable, then had youcalculate the DSO, then move to a lower DSO that would require a reduction in receivables, andthen determine the effects on ROE and EPS under different conditions. Similarly, we couldhave focused on fixed assets and the FA turnover ratio. In any of these cases, we could have hadyou use the funds generated to retire debt, which would have lowered interest charges and consequently increased net income and EPS.If we had to increase assets, then we would have had to finance this increase by adding eitherdebt or equity, which would have lowered ROE and EPS, other things held constant.Finally, note that we could have asked some conceptual questions about the problem, either as apart of the problem or without any reference to the problem. For example, "If funds are generatedby reducing assets, and if those funds are used to retire common stock, will the effect on EPSand/or ROE be affected by whether or not the stock sells above, at, or below book value?"7-12 a.

Computer models allow us to analyze quickly the impact of operating and financialdecisions on the firm's overall performance. A firm can analyze its financial ratios under different scenarios to see what might happen if a decision, such as the purchase of a new asset, did not produce the expected results. This gives the managers some idea about what might happen under the best and worst cases and helps them to make better decisions.。
1. Because very few securities will exhibit perfectly positive correlation,diversification will tend to reduce portfolio risk. Thus, for any given level of expected return, one would expect that portfolios will exhibit lower risk (lie further to the west in the feasible set) than individual portfolios (which will therefore lie to the east in the feasible set).2. Diversified portfolios are more efficient than individual securities. That is,diversified portfolios provide the investor with higher expected returns for given levels of risk and/or lower risk for given levels of expected return when compared with individual securities.Diagrammatically, individual securities will lie in the eastern portion of the feasible set. Hence they are dominated by diversified portfolios, which lie in the northwestern portion of the feasible set, including those on the efficient set.3. The macroeconomic forces that impact the U.S. economy tend to have a strongeffect on the earnings (and, hence, stock prices) of all domestic corporations, although the magnitude of this effect will vary among industries and specific firms.For example, a recession causes most companies to experience a downturn in earnings. While some companies may be more severely affected than others, nevertheless, the broad influence of a recession on general economic activity likely results in most companies' stocks performing poorly.Companies whose stocks would be expected to have a high positive covariance are auto and steel companies. When auto sales are strong (weak), the demand for steel generally rises (falls). The earnings of companies in both industries would rise and fall at roughly the same time and this movement would likely be anticipated by the earlier rise and fall of their stocks' prices.Companies whose stocks would be expected to have a low covariance are banks and gold mining firms. Rising interest rates and poor business conditions generally produce declining bank earnings. At the same time, a pessimistic economic outlook often causes investors to increase their demand for gold, which increases the price of gold and, therefore, the earnings of gold mining firms. The result is that the stock prices of banks and gold mining firms will not likely move in the same direction.4. It is the fact that all stocks do not have high positive covariances that causesdiversification to benefit the investor. That is, by diversifying, investors can reduce portfolio risk and thereby create more efficient portfolios. If stocks did have high positive covariances, then holding a well-diversified portfolio would not result in meaningful reductions in risk relative to holding individual securities.5. If the security in question had significant negative correlation with the rest of thesecurities in the portfolio, Mule might consider purchasing it even though it had anegative expected return. The diversifying nature of the security might reduce the risk of the portfolio sufficiently to make it attractive despite its inferior return potential.6. Given the expected returns and variance-covariance estimates for all securities, aninvestor can construct the efficient set. This information, combined with the unique risk-return preferences of the investor, allows the investor to determine his or her optimal portfolio. Diagrammatically, this optimal portfolio lies at the point of tangency between the investor's indifference curves and the efficient set.7. The standard deviation of a two-security portfolio is given by:[]σσσρσσp A A B B A B AB A B X X X X =++22122/In Dode's case:= [(.35)²(20)² + (.65)²(25)² + 2(.35)(.65)(20)(25) 12]½= [49 + 264 + 22812]½The portfolio's standard deviation will be at a minimum when the correlation between securities A and B is -1.0. That is:= [49 + 264 - 228]½= 9.2%The portfolio's standard deviation will be at a maximum when the correlation between securities A and B is +1.0. That is:= [49 + 264 + 228]½= 23.3%9.With a 12% expected return on the market index, the market model would imply that the expected return on Leslie's portfolio would be: r P = 1.5% + .90 ⨯ 12.0%= 12.3%10. Beta, as derived from the market model, is the slope of the regression line relatingthe return on a security (or portfolio) to the return on a market index.High beta stocks are termed "aggressive" because they will tend to produce morevolatile returns than the market index. When the market produces a positive return the high beta security will produce an even higher positive return. When the market generates a negative return the high beta security will produce an even lower negative return.Conversely, low beta securities are termed "defensive" because they tend to berelatively less sensitive to market moves. When the market produces a positive return, the low beta security's return will be less positive. When the market produces a negative return the low beta security will produce a less negative return.11.Estimating the slope of the characteristic line from the graph gives a beta value ofroughly 0.5 for Glenwood City Properties.13. The most important "complexity" potentially undermining the predictive power ofthe market model is that other factors besides the return on the market index may be closely associated with a security's return. For example, the return on General Motors stock may be associated with economic factors that affect primarily the auto industry. Ignoring those factors decreases the ability to effectively "explain" the return on General Motors stock through the market model.Further, the market model is based solely on the historical relationship between asecurity's return and the return on the market index. To the extent that relationship changes over time, the market model estimated over a past period may not predict the future well.In addition, the statistical technique used to generate the market model for aspecific security provides only an estimate of the relationship between the security's return and that of the market index. The estimation process is subject to sampling error.15. The market model defines a stock's return as:r i = i + ßi r I + iIn the case of Lyndon stock over the five years, the random error term can be -5510-10-5051015Market indexReturnGlenwood City Returncalculated as follows (assuming a 0% intercept term):1 = 17.2 - [(1.2) ⨯ (14.0)] = 0.42 = -3.1 - [(1.2) ⨯ (-3.0)] = 0.53 = 13.3 - [(1.2) ⨯ (10.0)] = 1.34 = 28.5 - [(1.2) ⨯ (25.0)] = -1.55 = 9.8 - [(1.2) ⨯ ( 8.0)] = 0.2The average random error term is: Average = (0.4 + 0.5 + 1.3 - 1.5 + 0.2)/5= 0.2The standard deviation of the random error term is therefore:= {[(0.4 - 0.2)² + (0.5 - 0.2)² + (1.3 - 0.2)²+ (-1.5 - 0.2)² + (0.2 - 0.2)²]/(5-1)}½= {(.04 + .09 + 1.21 + 2.89 + 0)/4}½= 1.03%16 The market risk of a portfolio depends on events that influence all securities tosome degree. That is, these events are systematic. Because all securities are affected by these systematic events, diversifying a portfolio will not reduce exposure to them. Only if the securities added to a portfolio had lower sensitivities to systematic events would diversification reduce market risk. But there is no reason to assume that randomly selected securities will have such lower sensitivities.The unique risk of a portfolio depends on events specific to individual securities comprising the portfolio. These events are unsystematic in the sense that an event that impacts one security (in either a good or bad sense) is not expected to impact other securities. As a result forming a diversified portfolio tends to cause the net impact of these unsystematic events to cancel each other out. The more diversified is the portfolio, the greater will be this canceling effect, and the lower is the portfolio's unique risk.Mathematically:σβσσεp i i n i I i i i n X X =⎛⎝ ⎫⎭⎪+⎡⎣⎢⎢⎤⎦⎥⎥==∑∑12222112/Looking at the market risk term:X i i i n I βσ=∑⎛⎝ ⎫⎭⎪122 Clearly, σI 2 is unaffected by diversification. Further, the term X i ßi is merely the average beta of the securities in the portfolio. Again, it is not affected by diversification.

金融市场与金融机构第七版米什金课后练习答案第一章为什么研究金融市场和金融机构1、为什么金融市场对经济的健康运行很重要?答:因为金融市场将资金从无生产性用途一方转向有生产性用途一方来提高经济效率。
2、当利率上升时,公司和消费方的经济行为可能发生怎样的变化?答:当利率上升时,公司将减少投资消费,因为融资的成本现在比以前高。
而消费者将更愿意将资金放入融资机构以收取利息,而不愿意购买房屋和汽车。
3、利率变化如何影响金融机构的收益性?答:利率的变化将会影响金融机构获取资金的成本,也会影响资产的收益,如贷款;除此之外,利率的改变还会影响金融机构所持股票或债券的价格,会导致收益或损失。
4、当利率上升时,是否每个人的情况都变坏了?答:不会。
利率上升时,贷款购买房屋和汽车的消费者境况会变坏,因为利息提高而付出更多资金;但是对于存款人而言,他们的收益会因利息的提升而增加。
5、股票价格下跌对商业投资可能会有什么影响?答:股票下跌对企业来说将会使其获取的资金变少,会减少投资规模,如:延迟建造本应提供更多就业机会的新厂房,也会减少对新设备的购买。
6、股票价格上升对消费者的购买决策可能造成什么影响?答:股票价格上升对于股票持有者的消费者来说他的财富增加了,也会刺激他去扩大消费。
7、英镑价值下跌如何影响英国的消费者?答:英镑价值下跌意味着外国商品更昂贵,购买进口商品的成本更高,消费者将减少对外国商品的购买,而会增加对本国产品的消费。
8、英镑价值上升对美国的商业活动影响如何?答:英镑价值上升使英国商品相对美国商品而言更加昂贵,美国企业会发现其产品在国内和国外更畅销,其产品的购买需求增加。
9、汇率变化如何影响金融机构的赢利性?答:汇率的变化会改变金融机构所持资产的价格,如此改变其相关资产的收益和损失。
同时也会影响金融机构在进行外贸交易时的利润。
10、观察图1-3,你会选择哪些年份去亚利桑那州而不是伦敦旅游?答:在1970S的中晚期、80S的晚期、90S早期美元的汇率都比较低,出境旅游相对而言比较昂贵,但是国内游将是黄金时期,可以去看看大峡谷;在80S早期,美元的汇率升高,出境游比较划算,可以去看看伦敦塔。
《金融学〔第二版〕》讲义大纲及课后习题答案详解第七章CHAPTER 7PRINCIPLES OF ASSET VALUATIONObjectives? Understand why asset valuation is important in finance.? Explain the Law of One Price as the principle underlying all asset-valuation procedures. ? Explain the meaning and role of valuation models.? Explain how information gets reflected in security prices.Outline7.1 The Relation Between an Asset’s Value and Its Price 7.2 Value Maximization and Financial Decisions 7.3 The Law of One Price and Arbitrage7.4 Arbitrage and the Prices of Financial Assets 7.5 Exchange Rates and Triangular Arbitrage 7.6 Interest Rates and the Law of One Price 7.7 Valuation Using Comparables 7.8 Valuation Models7.9 Accounting Measures of Value7.10 How Information Gets Reflected in Security Prices 7.11 The Efficient Markets HypothesisSummary? In finance the measure of an asset’s value is the price it would fetch if it were sold in a competitive market. Theability to accurately value assets is at the heart of the discipline of finance because many personal and corporate financial decisions can be made by selecting the alternative that maximizes value.? The Law of One Price states that in a competitive market, if two assets are equivalent they will tend to have thesame price. The law is enforced by a process called arbitrage, the purchase and immediate sale of equivalent assets in order to earn a sure profit from a difference in their prices.? Even if arbitrage cannot be carried out in practice to enforce the Law of One Price, unknown asset values canstill be inferred from the prices of comparable assets whose prices are known.? The quantitative method used to infer an asset’s value from information about the prices of comparable assets iscalled a valuation model. The best valuation model to employ varies with the information available and the intended use of the estimated value. ? The book value of an asset or a liability as reported in a firm’s financial statements often differs from its currentmarket value.? In making most financial decisions, it is a good idea to start by assuming that for assets that are bought and soldin competitive markets, price is a pretty accurate reflection of fundamental value. This assumption is generally warranted precisely because there are many well-informed professionals looking for mispriced assets who profit by eliminating discrepancies between the market prices and the fundamental values of assets. The proposition that an asset’s current price fully reflects all publicly-available information about future economic fundamentals affecting the asset’s value is known as the Efficient Markets Hypothesis.? The prices of traded assets reflect information about the fundamental economic determinants of their value.Analysts are constantly searching for assets whose prices are different from their fundamental value in order to buy/sell these “bargains.〞 In deciding the best strategy for the purchase/sale of a “bargain,〞 theanalyst has to evaluate the accuracy of her information. The market price of an asset reflects the weighted average of all analysts opinions with heavier weights for analysts who control large amounts of money and for those analysts who have better than average information.Instructor’s ManualChapter 7 Page 106Solutions to Problems at End of ChapterLaw of One Price and Arbitrage1. IBX stock is trading for $35 on the NYSE and $33 on the Tokyo Stock Exchange. Assume that the costs of buying and selling the stock are negligible. a. How could you make an arbitrage profit?b. Over time what would you expect to happen to the stock prices in New York and Tokyo?c. Now assume that the cost of buying or selling shares of IBX is 1% per transaction. How does this affectyour answer?SOLUTION:a. Buy IBX stock in Tokyo and simultaneously sell them in NY. Your arbitrage profit is $2 per share.b. The prices would converge.c. Instead of the prices becoming exactly equal, there can remain a 2% discrepancy between them, roughly $.70 inthis case.2. Suppose you live in the state of Taxachusetts which has a 16% sales tax on liquor. A neighboring state called Taxfree has no tax on liquor. The price of a case of beer is $25 in Taxfree and it is $29 in Taxachusetts.a. Is this a violation of the Law of One Price?b. Are liquor stores in Taxachusetts near the border with Taxfree going to prosper?SOLUTION:a. This is not a violation of the Law of One Price because it is due to a tax imposed in one state but not in the other.Illegal arbitrage will probably occur, with lawbreakers buying large quantities of liquor in Taxfree and selling it in Taxachusetts without paying the tax.b. It is likely that liquor stores will locate in Taxfree near the border with Taxachusetts. Residents of both stateswill buy their liquor in the stores located in Taxfree, and liquor stores in Taxachusetts will go out of business.Triangular Arbitrage3. Suppose the price of gold is 155 marks per ounce.a. If the dollar price of gold is $100 per ounce, what should you expect the dollar price of a mark to be?b. If it actually only costs $0.60 to purchase one mark, how could one make arbitrage profits?SOLUTION:a. $100 buys the same amount of gold (1 ounce) as 155 DM, so 1 DM should cost 100/155 or $.645.b. The marks are “cheaper〞 than they should be, so the arbitrage transaction requires you to buy marks at thecheap price, use them to purchase gold, and sell the gold for dollars. Example:1. Start with $1 million, which you borrow for only enough time to carry out the arbitrage transaction.2. Use the million dollars to buy 1,666,667 marks (1,000,000 / 0.60)3. Buy 10,752.69 ounces of gold (1,666,667 / 155)4. Sell the gold for $1,075,269 (10752.69 x 100)Your risk-free arbitrage profit is $75,269.4. You observe that the dollar price of the Italian lira is $0.0006 and the dollar price of the yen is $0.01. What must be the exchange rate between lira and yen for there to be no arbitrage opportunity?SOLUTION:.0006$/lira?.06Yen/lira.01$/YenInstructor’s ManualChapter 7 Page 1075. Fill in the missing exchange rates in the following table: US dollar British pound German mark Yen US dollar $1 $1.50 $.5 $.01 British pound £0.67 German mark DM2.0 Japanese ¥100 Yen SOLUTION: US dollar British pound German mark Japanese Yen US dollar $1 $1.50 $.5 $.01 British pound £0.67 1 = .67 / 2 = .67 / 100 German mark DM2.0 = 2 / .67 1 = 2 / 100 Japanese ¥100 = 100 / .67 = 100 / 2 1 Yen US dollar British pound German mark Japanese Yen US dollar $1 $1.50 $.5 $.01 British pound £0.67 £1 £.33 £.0067 German mark DM2.0 DM3.0 DM1.0 DM.02 Japanese ¥100 ¥150 ¥50 ¥1 Yen Valuation Using Comparables6. Suppose you own a home that you purchased four years ago for $475,000. The tax assessor’s office has just informed you that they are increasing the taxable value of your home to $525,000. a. How might you gather information to help you appeal the new assessment?b. Suppose the house next door is comparable to yours except that it has one fewer bedroom. It just sold for$490,000. How might you use that information to argue your case? What inference must you make about the value of an additional bedroom?SOLUTION:a. You should retrieve as much information as you can about recent sales of comparable homes. If you canconvince the assessor’s office that your home is comparable (and the market value of the recent sales is less than $525,000) you should have a good case. You can gather the information about home sales from a real estate broker.b. The difference between your house’s assessed value and the actual market value of the home next door is$35,000 ($525,000 - $490,000). If you can convince the tax assessor’s office that the value of a bedroom is less than $35,000, then the assessor must agree that your home is worth less than $525,000. For example, if comparable sales figures show that one additional bedroom (all else reasonably equivalent) is worth only $10,000, then you should be able to argue that your home is worth $500,000 rather than $525,000.7. The P/E ratio of ITT Corporation is currently 6 while the P/E ratio of the S&P 500 is 10. What might account for the difference? SOLUTION: There are several possible reasons:? ITT may be riskier than the S&P500 either because it is in a relatively risky industry or has a relatively higherdebt ratio.? ITT’s reported earnings may be higher than they are expected to be in the future, or they may be inflated due tospecial accounting methods used by ITT.Instructor’s ManualChapter 7 Page 1088. Suppose you are chief financial officer of a private toy company. The chief executive officer has asked you to come up with an estimate for the company’s price per share. Your company’s earnings per share were $2.00 in the year just ended. You know that you should look at public company comparables, however, they seem to fall into two camps. Those with P/E ratios of 8x earnings and those with P/E ratios of 14x earnings. You are perplexed at the difference until you notice that on average, the lower P/E companies have higher leverage than the higher P/E group. The 8x P/E group has a debt/equity ratio of 2:1. The 14x P/E group has a debt/equityratio of 1:1. If your toy company has a debt/equity ratio of 1.5:1, what might you tell the CEO about your company’s equity value per share? SOLUTION:It would be reasonable to apply a P/E of 11x earnings (= (8 + 14) / 2) because your leverage is midway between the two groups. Hence, your company’s price per share would be: 11x $2.00 = $22.00 per share.9. Assume that you have operated your business for 15 years. Sales for the most recent fiscal year were $12,000,000. Net income for the most recent fiscal year was $1,000,000. Your book value is $10,500,000. A similar company recently sold for the following statistics: Multiple of Sales: 0.8x Multiple of Net Income 12x Multiple of Book Value 0.9xa. What is an appropriate range of value for your company?b. If you know that your company has future investment opportunities that are far more profitable than thecompany above, what does that say about your company’s likely valuation? SOLUTION:a. Multiple of Sales: .8x = $12 million x .8 Multiple of Net Income 12x = $1 million x 12 Multiple of Book Value .9x = $10.5 million x .9 An appropriate range might be 9 to 12 millionb. Higher end of the range = $9.6 million = $12 million = $9.45 millionEfficient Markets Hypothesis10. The price of Fuddy Co. stock recently jumped when the sudden unexpected death of its CEO was announced. What might account for such a market reaction?SOLUTION:Investors may believe that the company’s future prospects look better(i.e., either higher earnings or less risky) without the deceased CEO.11. Your analysis leads you to believe that the price of Outel’s stock should be $25 per share. Its current market price is $30.a. If you do not believe that you have access to special information about the company, what do you do?b. If you are an analyst with much better than average information, what do you do?SOLUTION:a. If you believe that the market for Outel stock is an informationally efficient one then the $30 market price(which is a weighted average of the valuations of all analysts) is the best estimate of the stock’s true value. You should question whether your own analysis is correct.b. You sell the stock because you think you have superior information. Real Interest Rate Parity12. Assume that the world-wide risk-free real rate of interest is 3% per year. Inflation in Switzerland is 2% per year and in the United States it is 5% per year. Assuming there is no uncertainty about inflation, what are the implied nominal interest rates denominated in Swiss francs and in US dollars?SOLUTION: Switzerland: (1.03 x 1.02) =1.0506 hence nominal interest rate = 5.06% US: (1.03 x 1.05) = 1 .0815 hence nominal interest rate = 8.15%Instructor’s ManualChapter 7 Page 109Integrative Problem13. Suppose an aunt has passed away and bequeathed to you and your siblings (one brother, one sister) a variety of assets. The original cost of these assets follows:ITEM COST WHEN PURCHASEDJewelry $500 by Grandmother 75 years ago House 1,200,000 10 years ago Stocks and Bonds 1,000,000 3 years ago Vintage (used) Car 200,000 2 months ago Furniture 15,000 various dates during last 40 yearsBecause you are taking a course in finance, your siblings put you in charge of dividing the assets fairly among the three of you. Before you start, your brother approaches you and says: “I’d really like the car for myself, so when you divide up the assets, just give me the car and deduct the $200,000 from my share.〞Hearing that, your sister says: “That sounds fair, because I really like the jewelry and you can assign that to me and deduct the $500 from my share.〞You have always loved your aunt’s house and its furnishings, so you would like to keep the house and the furniture.a. How do you respond to your brother and sister’s requests? Justify your responses.b. How would you go about determining appropriate values for each asset?SOLUTION:a. Because the market price of the car is close to the what your brother is willing to give up for it, your brother’srequest is reasonable. It is, however, quite possible (even likely), that the antique jewelry is worth much more today than what your relative’s grandmother paid for it in the past. Assigning only its acquisition cost to your sister’s share is quite likely a gross miscalculation. If she wants the jewelry, she should be “charged〞 an amount equal to today’s market value. It does not matter that your sister does not want to sell the jewelry for a profit, because the jewelry has VALUE even if you do not sell it. Fairness is all about equal VALUE.b. You would probably have to hire a professional appraiser for the furniture and the jewelry. You can look up thevalue of the stocks and bonds in a financial newspaper. You can estimate the value of the house by inquiring for how much similar houses in the same neighborhood have recently been sold. The car was purchased only twomonths ago, so it is probably reasonable to assume that the current market price is very close to what your distant relative paid for the car.

精品行业资料,仅供参考,需要可下载并修改后使用!《金融基础知识》课后习题答案第7章习题答案 1. (1)交易成本的假设:BS 模型假定无交易成本,可以连续进行动态的套期保值,但事实上交易成本总是客观存在的。
(2)波动率为常数的假设:实际上波动率本身就是一个随机变量。
(3)不确定的参数:BS 模型假设波动率、利率、股利等参数都是已知的常数(或是已知的确定函数)。
但事实上它们都不是一个常数,最为典型的波动率甚至也不是一个时间和标的资产价格的确定函数,并且完全无法在市场观察到,也无法预测。
(4)资产价格的连续变动:在实际中,不连续是常见的,资产价格常常出现跳跃。
2. 交易成本的存在,会影响我们进行套期保值的次数和期权价格:交易成本一方面会使得调整次数受到限制,使基于连续组合调整的BS 模型定价成为一种近似;另一方面,交易成本也直接影响到期权价格本身,使得合理的期权价格成为一个区间而不是单个数值。
同时,不同的投资者需要承担的交易成本不同,具有规模效应,即使是同一个投资者,处于合约多头和空头时,期权价值也不同。
3. 在放松布莱克-舒尔斯模型假设之后,常常出现非线性的偏微分方程,这意味着同一个组合中的期权头寸可能出现互相对冲和保值,减少了保值调整成本,从而使得整个组合的价值并不等于每个期权价值之和,因此组合中一份衍生证券合约的价值往往取决于该组合中其他合约的价值。
4. 应用期权的市场价格和BS 公式推算出来的隐含波动率具有以下两个方面的变动规律:(1)“波动率微笑”:隐含波动率会随着期权执行价格不同而不同;(2)波动率期限结构:隐含波动率会随期权到期时间不同而变化。
通过把波动率微笑和波动率期限结构放在一起,可以构造出一个波动率矩阵,它是我们考察和应用波动率变动规律的基本工具之一。
波动率微笑和波动率期限结构的存在,证明了BS 公式关于波动率为常数的基本假设是不成立的,至少期权市场不是这样预期的。
实际从业人员常常从隐含波动率矩阵中获取市场对资产价格分布的信息和预期,从而为衍生证券尤其是那些交易不活跃的期权定价。

现有两种策略:直接购买股票或投资于期权,请问各自潜在的收益或损失为多少?答:股票价格低于$29时,购买股票和期权都将损失,前者损失为$5,800$29×(29-p),后者损失为$5,800;当股票价格为(29,30),购买股票收益为$5,800$29×(p-29),购买期权损失为$5,800;当股票价格高于$30时,购买股票收益为$5,800 $29×(p-29),购买期权收益为$$5,800$29×(p-30)-5,800。

1.a,在纽约买IBM公司的股票同时在NYSE卖出,你将获得每股2美圆的套利
b,经过一段时间后,两地价格将会相等。
c,假定购买股票的成本为每笔交易额的1%,就将会有一个2%的差异,在这个事例中大概有0。
70美圆
2.a,这是违背一价定理的,这是因为在一个洲有强加的销售税,而另一个州却没有,不合法的套利行为将发生,违法者将在免税的州买进大量的酒,而在有征税的州卖出,却不付税
b,很有可能酒店将开在免税的州并且靠近有征税的州的边境上,居名将会在免税的商店买酒,有征税的州的商店将会没有生意
3. a、由于1盎司黄金值$100和DM155,所以1马克应该价值100/155=$0.645。
b、市场价格比其应该的价格要便宜,用美元兑换成马克,再用马克购买黄金,最后再用黄金换回美元。
例如:
1)开始你有1百万美元,那时你所能筹集到的最多的资金来进行三角套利。
2)用这1百万美元购买1666667马克
3)再用马克购买10752.69盎司黄金
4)把黄金兑换成1075269美元
从而你能得到75269美元

a, 你应该尽量找一些最近所销售的可比房屋的信息和情况,如果你能说服税务所,你的房屋与最近销售的房屋是可比较的,而最近
所销售的可比房屋的市价低于$525,000,你就会得到一个好的评
估结果。
你可以从房地产经纪人那里得到你想要的信息。
b, 你房子的估价和你隔壁公寓的市价差额是$35,000 ($525,000 -$490,000)。
如果你能说服税务所,隔壁公寓所缺少的卧室的市
价少于$35,000,税务所就会同意你的观点,你的房子的估价应
该少于$525,000。
举个例子,如果一个可比房屋的销售曲线图显
示,增加一间房间(或其他类似的东西)的市价是$10,000,你
就可以说,你的房子的估价应该是$500,000而不是$525,000。

可能的原因是:
ITT公司的风险高于标准普尔500,也许它本身就是个高风险行业,或者有更高的负债率。
ITT公司所公布的销售额比它们预期的还高。
或者他们使用了特殊的会计准则,导致通货膨胀(或许通胀是因为ITT的新算法。
)
8,
很合理地,你的P/E为11 (= (8 + 14) / 2),(申请一个 P/E of 11x 盈利 (= (8 + 14) / 2)),因为你的负债权益比刚好在这两个公司之间。
所以,你的公司每股价值是11x $2.00 = $22.00。

a,销售额的倍数 0.8 x = $12000000 x 0.8
= $9600000
净收入的倍数 12 x = $1000000 x 12
= $12000000
帐面价值的倍数 0.9 x = $10500000 x 0 .9 = $9450000
公司的价值区间应该是 9000000 到 12000000
b,比区间的最大值还多
10.投资者有可能相信没有这个糟糕的CEO公司的未来预期会更好(比
如可能会赚得更多或有更低的风险)。
11.A.如果你相信对于Outel的股票来说,市场是信息完全而有效率的,那么它的市价30美元(这是对所有估价分析的平均权重)是对股票真实价值的最好估计。
你就应该分析一下你自己的分析是否正确。
B.你把股票卖掉,因为你有超前的信息。
12.瑞士:(1.03*1.02)=1.0506,因此名义利率是5.06%
美国:(1.03*1.05)=1.0815,因此名义利率是8.15%
13.a.由于那辆车的市场价格和你弟弟愿意为之放弃的遗产数额相当接近,所以你弟弟的请求是合理的。
但是,很可能地,那些古老的珠宝今天的市场价格要比你祖母当年购买时所支付的金额高很多,所以,仅仅按帐面价值把珠宝分配到你妹妹的份额里极可能会导致重大的计算错误。
如果她真的想要那些珠宝的话,那么她必须被索取与当前那些珠宝的市场的价值相匹配的金额。
就算你妹妹并不打算在拥有那些珠宝后就把他们卖掉以获取利润,你也要按当前市场价格计算珠宝的价值,因为即使你不卖掉它们,珠宝同样具有价值。
公平就是要求每个人拥有等同的价值。
b.你也许需要雇佣一个专业的鉴定专家来鉴定那些家具和珠宝的价值。
你可以在金融报纸上查阅那些股票和债券的价值。
你可以通过询问同一街区里相似房屋最近的出售价格以估计遗留下来的房屋的价值。
由于汽车是在2个月前购买的,所以假定,那辆车的当前市场价格很接近于你姑妈购买时的支付额,是合情合理的。
