金融市场与金融机构中文答案【篇一：fabozzi_金融市场与金融机构基础课后答案】the u.s. federal reserveand the creation of moneycentral banks and their purposethe primary role of a central bank is to maintain the stability of the currency and money supply for a country or a group of countries. the role of central banks can be categorized as: (1) risk assessment, (2) risk reduction, (3) oversight of payment systems, (4) crisis management.one of the major ways a central bank accomplishes its goals is through monetary policy. for this reason, central banks are sometimes called monetary authority. in implementing monetary policy, central banks, acting as a reserve bank, require private banks to maintain and deposit the required reserves with the central bank. in times of financial crisis, central banks perform the role of lender of last resort for the banking system. countries throughout the world may have central banks. additionally, the european central bank is responsible for implementing monetary policy for the member countries of the european union.in implementing monetary and economic policies, the united states is a member of an informal network of nations. this group started in 1976 as the group of 6, or g6: us, france, germany, uk, italy, and japan. thereafter, canada joined to for the g7. in 1998, russia joined to form the g8.the central bank of the united states: the federal reserve systemthe federal reserve system consists of 12 banking districts covering the entire country. created in 1913, the federal reserve is the government agency responsible for the management of the us monetary and banking systems. it is independent of the political branches of government. the fed is managed by a seven-member board of governors, who are appointed by the president and approved by congress.the fed’s tools for monetary management have been made more difficult by financial innovations. the public’s increasing acceptance of money market mutual funds has funneled alarge amount of money into what are essentially interest-bearing checking accounts. securitization permits commercial banks to change what once were illiquid consumer loans of several varieties into securities. selling these securities gives the banks a source of funding that is outside the fed’s influence.instrument of monetary policy: how the fed influences the supply of moneythe fed has three instruments at its disposal to affect the level of reserves.under our fractional reserve banking system have to maintain specified fractional amounts of reserves against their deposits. the fed can raise or lower these required reserve ratios, thereby permitting banks to decrease or increase their lending and investment portfolios. a bank’s total reserves equal its required reserves plus any excess reserves.the fed’s most powerful instrument is its authority to conduct open market operation. it buys and sells in open debt markets government securities for its own accounts. the fed prefers to use treasury bills because it can make its substantial transactions without seriously disrupting the prices or yields of bills.the federal open market committee, or fomc, is the unit that decides on the general issues of changing the rate of growth in the money supply, by open market sales or purchases of securities. the implementation of policy through open market operations is the responsibility of the trading desk of the federal reserve bank of new york.the fed often employs variants of simple open market purchases and sales, these are called the repurchase agreement (or repo) and the reverse repo. in a repo, the fed buys a particular amount of securities from a seller that agrees to repurchase the same number of securities for a higher price at some future time. in a reverse repo, the fed sells securities and makes a commitment to buy them back at a higher price later.a bank borrowing from the fed is said to use the discount window. the discount rate is the rate charged to banks borrowing directly from the fed. raising the rate is designed todiscourage such borrowing, while lowering should have the opposite effect.different kinds of moneymoney is that item which serves as a numeraire. in a basic sense money can be defined as anything that serves as a unit of account and medium of exchange. we measure prices in dollars and exchange dollars for goods. hence coins, currency, and any items readily exchanged into dollars (checking deposits or now accounts) constitute our money supply.money and monetary aggregatesmonetary aggregates measure the amount of money available to the economy at any time. the monetary base is defined as currency in circulation (coins and federal reserve notes) and reserves in the banking system. the instruments that serve as a medium of exchange can be narrowly defined as m1, which is currency and demand deposits. m2 is m1 plus time and savings accounts, and money market mutual funds. finally, m3 is m2 plus short-term treasury liabilities. while all three aggregates are watched and monitored, m1 is the most common form of the money supply, with its trait as being the most liquid. the ratio of the money supply to the economy’s income is known as the velocity of money.the money multipier: the expansion of the money supplythe money multiplier effect arises from the fact that a small change in reserves can produce a large change in the money supply. through our fractional reserve system, a small increase will allow an individual bank, to lend out the greater part of these additional funds. these loans subsequently become deposits in other banks allowing them to expand proportionately. so, while one bank can expand its loans (or deposits) by an amount 1% of reserves required, all banks in the system can do likewise. thus, in a simple format total change in deposits can be stated as change in reserves divided by the reserve requirement, which is also the formula for perpetuity. for example, if the change in the level of reserves is $100 and the reserve requirement is 20%, the change in total deposits will be $500 for a multiplier of 5. of course, major assumptions are that banks will fully loan out their excess reserves and that depositors will not withdraw any of these extra reserves.the impact of interest rates on the money supplyhigh rates of interest may make keeping excess reserves costly, since unused funds represent loans not made and interest not earned. high rates of interest will also affect the public’s demand for hol ding cash. if deposits pay competitive interest rates, customers will be more willing to hold such bank liabilities and less cash. therefore, a higher rate of interest can actually spur growth of the money supply. more likely, however, it will deter borrowing and slow monetary growth.the money supply process in an open economyin the modern era, almost every country has an open economy. foreign commercial and central banks hold dollar accounts in the united states. their purchases and sales of these deposits can affect exchange rates of the dollar against their own currency. the fed has responsibility for maintaining stability in exchange rates. a purchase of foreign exchange with dollars depreciates the dollar’s value, but it also adds dollars to the accounts of foreign banks in this country, thus adding to the u.s. monetary base. most central banks of large economies own or stand ready to own a large amount of each of the world’s major currencies, which are considered international reserves. sales of foreign exchange transactions have monetary base implication and hence consequences for the domestic money supply, emphasis is given to coordinating monetarypolicies among developed nations.answers to questions for chapter 4(questions are in bold print followed by answers.)1. what is the role of a central bank?the role of a central bank has several functions: risk assessment, risk reduction, oversight of payment systems, and crisis management. it can do this through monetary policies, and through the implementation of regulations.2. why is it argued that a central bank should be independent of the government?central banks should be independent of the short-term political interests and political influences generally in setting economic policies.3. identify each participant and its role in the process bywhich the money supply changes and monetary policy is implemented.the fed determines monetary policy and seeks to implement it through changes in reserves. it is up to the nation’s banking system to act on changes in reserves thereby affecting deposits, which constitute the greater part of the m1 definitionof the money supply.4. describe the structure of the board of governors of the federal reserve system.the board of governors of the federal reserve system consistsof 7 members who are appointed to staggered 14-year terms.the board reviews discount operations and sets legal reserve requirements. in addition, all 7 members of the board serve on the federal open market committee (fomc), which determinesthe direction and magnitude of open-market operations. such operations constitute the key instrument for implementing monetary policy.5.a. explain what is meant by the statement “the united stateshas a fractional reserve banking system.”b. how are these items related: total reserves, required reserves, and excess reserves?a. a fractional reserve system requires that a fraction orpercent of a bank’s reserve be placed either in currency invault or with the federal reserve system.b. total reserves are the amounts that banks hold in cash or at the fed. required reserves are amounts required by the fed to meet some specific or legal reserve ratio to deposits. excess reserves are bank reserves in currency and at the fed whichare in excess of legal requirements. since these amounts arenon-interest bearing, banks are often willing to lend these surplus funds to deficit banks at the fed funds rate.【篇二：金融市场与金融机构基础(第9章) 英文版答案】ter 9(questions are in bold print followed by answers.)1. your broker is recommending that you purchase u.s. government bonds. here is the explanation: listen, in thesetimes of uncertainty, with many companies going bankrupt, itmakes sense to play it safe and purchase long-term government bonds. they are issued by the u.s. government, so they are risk free. how would you respond to the broker?u.s. government bonds may be free of default risk, but they are not free from interest rate risk, which may cause the bond price to decline, resulting in a capital loss should the holder of bond sell it before maturity. even then there is the inflation premium risk, which means that the principal may have less purchasing power at maturity than it does today.2. you just inherited 30,000 shares of a company you have never heard of, abd corporation. you call your broker to find out if you have finally struck it rich. afterseveral minutes, she comes back on the telephone and says: “i don’t have a clue about these shares. it’s too bad they are not traded in a financial market. that would make life a lot easier for you. ”what does she mean by this?if the shares are traded on the market, and if the market is efficient, the current price would denote the value of the stock. without market price information, share value would have to be approximated through other time-consuming and less reliable methods.3. suppose you own a bond that pays $75 yearly in coupon interest and that is likely to be called in two years (because the firm has already announced that it will redeem the issue early). the call price will be $1,050.what is the price of your bond now, in the market, if the appropriate discount rate for this asset is 9%?po = $75 (pvifa) 2.09 + $1050 (pvif) 2.09= $75 x 1.7591 + $1050 x .8417 = $1015.724. your broker has advised you to buy shares of hungry boy fast foods, which has paid a dividend of $1.00 per year for 10 years and will (according to the broker) continue to do so for many years. the broker believes that the stock, which now has a price of $12, will be worth $25 per share in five years. you have good reason to think that the discount rate for this firm’s stock is 22% per year, because that rate compensates the buyer for all pertinent risks. is the stock’s present price a good approximation of its true financial value?po = $1 (pvifa) 5.22 + $25 x (pvif) 5.22 = .3715 = $12.15the price is right, in fact the stock is slightly undervalued.5. you have been considering a zero-coupon bond, which pays no interest but will pay a principal of $1,000 at the end of five years. the price of the bond is now $712.99, and its required rate of return is 7.0%. this morning’s news contained a surprising development. the government announced that the rate of inflation appears to be 5.5% instead of the 4% that most people had been expecting. (suppose most people had thought the real rate of interest was 3%.) what would be the price of the bond, once the market began to absorb this new information about inflation?the nominal required rate of return is (real rate plus inflation) ir + if or currently 3% plus 4% = 7%. if if becomes 5.5% then the new required rate of return becomes 8.5%. the price of the bond would then be $1000/(1.085)5 or $665.05.6. state the difference in basis points between each of the following:a. 5.5% and 6.5%b. 7% and 9%c. 6.4% and 7.8%d. 9.1% and 11.9%a. 100 basis pointsb. 200 basis pointsc. 140 basis pointsd. 280 basis points7.a. does a rise of 100 basis points in the discount rate change the price of a 20-year bond as much as it changes the price of a four-year bond, assuming that both bonds have the same coupon rate and offer the same yield?b. does a rise of 100 basis points in the discount rate change the price of a 4% coupon bond as much as it changes the price of a 10% coupon bond, assuming that both bonds have the same maturity and offer the same yield?c. does a rise of 100 basis points in the discount rate change the price of a 10-year bond to the same extent if the discount rate is 4% as it does if the discount rate is 12%?a. the price of the 20-year bond will fall more than that of the 4-year bond because there are more years for the new discount to apply to the cash flows of the 20-year bond.b. the price of the low coupon bond will change more due to the low amount of cash flows that can be reinvested at the higher rate.c. a change from the 4% base will lead to a larger change in price.8.during the early 1980s, interest rates for many long-term bonds were above 14%. in the early 1990s, rates on similar bonds were far lower. what do you think this dramatic decline in market interest rates means for the price volatility of bonds in response to a change in interest rates?since the direction of the interest rate change is downward, price volatility should increase.9.a. what is the cash flow of a 6% coupon bond that pays interest annually, matures in seven years, and has a principal of $1,000?b. assuming a discount rate of 8%, what is the price of this bond?c. assuming a discount rate of 8.5%, what is the price of this bond?d. assuming a discount rate of 7.5%, what is the price of this bond?e. what is the duration of this bond, assuming that the price is the one you calculated in part (b)?f. if the yield changes by 100 basis points, from 8% to 7%, by how much would you approximate the percentage price change to be using your estimate of duration in part (e)?g. what is the actual percentage price change if the yield changes by 100 basis points?a. $60 a year interest for 7 years plus $1000 principal in year 7 for a total of $1420 in cash flow.b. 5.2064 x $60 + .583 x $1000 = $895.38c. 5.119 x $60 + .565 x $1000 = $872.14d. 5.297 x $60 + .603 x $1000 = $920.82e. =$48.68/8.95=5.44$895.38 (0.85-.075)f. applying the formula-d (change in yield) = -5.44 (.01) or a price increase of 5.42%.g. price at 8% =$895.88, at 7% = $946.06, so actual percentage change is ($946.06 - $895.88)/$895.88=5.6%.10. why is it important to be able to estimate the duration of a bond or bond portfolio?to answer this question, we must understand that duration is related to percentage price change.a simple formula can be used to calculate the approximate duration of a bond or bond portfolio. all we are interested in is the percent price change of a bond when interest rates change by a small amount. to control interest rate risk, it is thus necessary to be able to measure it. duration provides that measure.11. explain why you agree or disagree with the following statement: “determining the duration of a financial asset is a simple process.”disagree. determining the duration of a financial asset is not simple process. because for most assets, the cash flow can change when interest rates change. therefore, if a change in the cash flow is not considered, duration calculations can be misleading.12. explain why the effective duration is a more appropriate measure of a complexfinancial instrument’s price sensitiv ity to interest rate changes than is modified duration.modified duration is derived with the assumption that cash flows do not change as interest rates change. effective duration is calculated with the assumption of changing cash flows. for complex finan cial instruments’ price sensitivity to interest rate changes could be very large. hence, the importance of effective duration becomes significant.【篇三：米什金《金融市场与金融机构》课后习题及其答案】class=txt>345。
