曼昆经济学原理英⽂版⽂案加习题答案29章THE MONETARY SYSTEMWHAT’S NEW IN THE S EVENTH EDITION:There is a new In the News box on ―Why Gold?‖LEARNING OBJECTIVES:By the end of this chapter, students should understand:what money is and what functions money has in the economy.what the Federal Reserve System is.how the banking system helps determine the supply of money.what tools the Federal Reserve uses to alter the supply of money.CONTEXT AND PURPOSE:Chapter 16 is the first chapter in a two-chapter sequence dealing with money and prices in the long run. Chapter 16 describes what money is and develops how the Federal Reserve controls the quantity of money. Because the quantity of money influences the rate of inflation in the long run, the followingchapter concentrates on the causes and costs of inflation.The purpose of Chapter 16 is to help students develop an understanding of what money is, what forms money takes, how the banking system helps create money, and how the Federal Reserve controls the quantity of money. An understanding of money is important because the quantity of money affects inflation and interest rates in the long run, and production and employment in the short run.KEY POINTS:The term money refers to assets that people regularly use to buy goods and services.Money serves three functions. As a medium of exchange, it is the item used to make transactions. Asa unit of account, it provides the way in which prices and other economic values are recorded. As astore of value, it offers a way to transfer purchasing power from the present to the future.264Chapter 16/The Monetary System ? 265Commodity money, such as gold, is money that has intrinsic value: It would be valued even if it were not used as money. Fiat money, such as paper dollars, is money without intrinsic value: It would be worthless if it were not used as money.In the U.S. economy, money takes the form of currency and various types of bank deposits, such as checking accounts. The Federal Reserve, the central bank of the United States, is responsible for regulating the U.S. monetary system. The Fed chairman is appointed by the president and confirmed by Congress every four years. The chairman is the lead member of the Federal Open Market Committee, which meets about every six weeks to consider changes in monetary policy.Bank depositors provide resources to banks by depositing their funds into bank accounts. These deposits are part of a bank’s liabilities. Bank owners also provide resources (called bank capital) for the bank. Because of leverage (the use of borrowed funds for investment), a small change in the value of a bank’s assets can lead to a large change in the value of the bank’s capital. To protect depositors, bank regulators require banks to hold a certain minimum amount of capital.The Fed controls the money supply primarily through open-market operations. The purchase of government bonds increases the money supply, and the sale of government bonds decreases the money supply. The Fed also uses other tools to control the money supply. It can expand the money supply by decreasing the discount rate, increasing its lending to banks, lowering reserverequirements, or decreasing the interest rate on reserves. It can contract the money supply by increasing the discount rate, decreasing its lending to banks, raising reserve requirements or increasing the interest rate on reserves.When individuals deposit money in banks and banks loan out some of these deposits, the quantity of money in the economy increases. Because the banking system influences the money supply in this way, the Fed’s control of the money supply is imperfect.The Federal Reserve has in recent years set monetary policy by choosing a target for the federal funds rate, a short-term interest rate at which banks make loans to one another. As the Fed achieves its target, it adjusts the money supply. CHAPTER OUTLINE:I. The Meaning of Money266?Chapter 16/The Monetary SystemA. Definition of money: the set of assets in an economy that people regularly use to buygoods and services from other people.B. The Functions of Money1. Money serves three functions in our economy.a. Definition of medium of exchange: an item that buyers give to sellers when theywant to purchase goods and services.b. Definition of unit of account: the yardstick people use to post prices and recorddebts.c. Definition of store of value: an item that people can use to transfer purchasingpower from the present to the future.2. Definition of liquidity: the ease with which an asset can be converted into theeconomy’s medium of exchange.a. Money is the most liquid asset available.b. Other assets (such as stocks, bonds, and real estate) vary in their liquidity.c. When people decide how to allocate their wealth, they must balance the liquidity of each possible asset against t he asset’s usefulness as a store of value.C. The Kinds of Money1. Definition of commodity money: money that takes the form of a commodity withintrinsic value.2. Definition of fiat money: money without intrinsic value that is used as moneybecause of government decree.3. In the News: Why Gold?a. Historically, societies have used gold, rather than other commodities, for commodity money.b. This article from NPR Morning Edition describes why gold is the best choice for commodity money.D. Money in the U.S. Economy1. The quantity of money circulating in the United States is sometimes called the money stock.2. Included in the measure of the money supply are currency, demand deposits, and other monetary assets.a. Definition of currency: the paper bills and coins in the hands of the public.b. Definition of demand deposits: balances in bank accounts that depositors canaccess on demand by writing a check.Chapter 16/The Monetary System?2673. Figure 1 shows the monetary assets included in two important measures of the money supply, M1 and M2.4. FYI: Why Credit Cards Aren’t Moneya. Credit cards are not a form of money; when a person uses a credit card, he or she issimply deferring payment for the item.b. Because using a debit card is like writing a check, the account balances that lie behind debit cards are included in the measures of money.5. Case Study: Where Is All the Currency?a. If we divide the amount of outstanding currency in the United States by the adult population, we find that the average adult should have approximately $4,490 in currency.b. Of course, most adults carry a much smaller amount.c. One explanation is that a great deal of U.S. currency may be held in other countries.d. Another explanation is that large amounts of currency may be held by criminals because transactions that use currency leave no paper trail.II. The Federal Reserve SystemA. Definition of Federal Reserve (Fed): the central bank of the United States.B. Definition of central bank: An institution designed to oversee the banking system and regulate the quantity of money in the economy.268?Chapter 16/The Monetary SystemC. The Fed’s Organization1. The Fed is run by a Board of Governors with 7 members who serve 14-year terms.a. The Board of Governors has a chairman who is appointed for a four-year term.b. The current chairman is Ben Bernanke.Chapter 16/The Monetary System ? 2692. The Federal Reserve System is made up of 12 regional Federal Reserve Banks located in major cities around the country.3. One job performed by the Fed is the regulation of banks to ensure the health of the nation’s banking system.a. The Fed monitors each bank's financial condition and facilitates bank transactions byclearing checks.b. The Fed also makes loans to banks when they want to borrow.4. The second job of the Fed is to control the quantity of money available in the economy.a. Definition of money supply: the quantity of money available in the economy .b. Definition of monetary policy: the setting of the money supply by policymakersin the central bank .D. The Federal Open Market Committee1. The Federal Open Market Committee (FOMC) consists of the 7 members of the Board ofGovernors and 5 of the 12 regional bank presidents. 2. The primary way in which the Fed increases or decreases the number of dollars in theeconomy is through open market operations (which involve the purchase or sale of U.S. government bonds).a. If the Fed wants to increase the supply of money, it creates dollars and uses them topurchase government bonds from the public through the nation's bond markets.b. If the Fed wants to lower the supply of money, it sells government bonds from itsportfolio to the public. Money is then taken out of the hands of the public and the supply of money falls.III. Banks and the Money Supply270 ? Chapter 16/The Monetary SystemA. The Simple Case of 100-Percent-Reserve Banking 1. Example: Suppose that currency is the only form of money and the total amount of currencyis $100. 2. A bank is created as a safe place to store currency; all deposits are kept in the vault until thedepositor withdraws them.a. Definition of reserves: deposits that banks have received but have not loanedout . b. Under the example described above, we have 100-percent-reserve banking.3. The financial position of the bank can be described with a T-account:4. The money supply in this economy is unchanged by the creation of a bank.a. Before the bank was created, the money supply consisted of $100 worth of currency.b. Now, with the bank, the money supply consists of $100 worth of deposits.5. This means that, if banks hold all deposits in reserve, banks do not influence the supply of money. B. Money Creation with Fractional-Reserve Banking1. Definition of fractional-reserve banking: a banking system in which banks hold onlya fraction of deposits as reserves .2. Definition of reserve ratio: the fraction of deposits that banks hold as reserves .3. Example: Same as before, but First National decides to set its reserve ratio equal to 10% andlend the remainder of the deposits.4. The bank’s T -account would look like this:Chapter 16/The Monetary System ? 2715. When the bank makes these loans, the money supply changes.a. Before the bank made any loans, the money supply was equal to the $100 worth ofdeposits.b. Now, after the loans, deposits are still equal to $100, but borrowers now also hold $90worth of currency from the loans.c. Therefore, when banks hold only a fraction of deposits in reserve, banks create money. 6. Note that, while new money has been created, so has debt. There is no new wealth createdby this process. C. The Money Multiplier1. The creation of money does not stop at this point.2. Borrowers usually borrow money to purchase something and then the money likely becomesredeposited at a bank.3. Suppose a person borrowed the $90 to purchase something and the funds then getredeposited in Second National Bank. Here is this bank’s T -account (assuming that it also sets its reserve ratio to 10%):4.If the $81 in loans becomes redeposited in another bank, this process will go on and on. 5. Each time the money is deposited and a bank loan is created, more money is created.6. Definition of money multiplier: the amount of money the banking system generateswith each dollar of reserves .7. In our example, the money supply increased from $100 to $1,000 after the establishment of fractional-reserve banking.ALTERNATIVE CLASSROOM EXAMPLE:Reserve ratio = 12.5%Money multiplier = 1/0.125 = 8272?Chapter 16/The Monetary SystemD. Bank Capital, Leverage, and the Financial Crisis of 2008–20091. In reality, banks also get funds from issuing debt and equity.2. Definition of bank capital: the resources a bank’s owners have put into theinstitution.3. A more realistic balance sheet for a bank:4. Definition of leverage: the use of borrowed money to supplement existing funds for purposes of investment.5. Definition of leverage ratio: the ratio of assets to bank capital.a. The leverage ratio is $1,000/$50 = 20.b. A leverage ratio of 20 means that, for every dollar of capital that has been contributed by the owners, the bank has $20 of assets.c. Because of leverage, a small chang e in assets can lead to a large change in owner’s equity.6. Definition of capital requirement: a government regulation specifying a minimumamount of bank capital.7. In 2008 and 2009, many banks realized they had incurred sizable losses on some of their assets.IV. The Fed’s Tools of Monetary ControlA. How the Fed Influences the Quantity of Reserves1. Open-Market Operationsa. Definition of open-market operations: the purchase and sale of U.S. governmentbonds by the Fed.b. If the Fed wants to increase the supply of money, it creates dollars and uses them to purchase government bonds from the public in the nation's bond markets.c. If the Fed wants to lower the supply of money, it sells government bonds from its portfolio to the public in the nation's bond markets. Money is then taken out of the handsof the public and the supply of money falls.d. If the sale or purchase of government bonds affects the amount of deposits in the banking system, the effect will be made larger by the money multiplier.Chapter 16/The Monetary System?273e. Open market operations are easy for the Fed to conduct and are therefore the tool of monetary policy that the Fed uses most often.2. Fed Lending to Banksa. The Fed can also lend reserves to banks.b. Definition of discount rate: the interest rate on the loans that the Fed makes tobanks.c. A higher discount rate discourages banks from borrowing from the Fed and likely encourages banks to hold onto larger amounts of reserves. This in turn lowers themoney supply.d. A lower discount rate encourages banks to lend their reserves (and borrow from the Fed). This will increase the money supply.e. In recent years, the Fed has set up new mechanisms for banks to borrow from the Fed.B. How the Fed Influences the Reserve Ratio1. Reserve Requirementsa. Definition of reserve requirements: regulations on the minimum amount ofreserves that banks must hold against deposits.b. This can affect the size of the money supply through changes in the money multiplier.c. The Fed rarely uses this tool because of the disruptions in the banking industry that would be caused by frequent alterations of reserve requirements. (It is also not effective when banks hold a lot of excess reserves.)2. Paying Interest on Reservesa. In October of 2008, the Fed began paying banks interest on reserves.b. The higher the interest rate, the more reserves a bank will want to hold. This will reducethe money multiplier and the money supply.C. Problems in Controlling the Money Supply1. The Fed does not control the amount of money that consumers choose to deposit in banks.a. The more money that households deposit, the more reserves the banks have, and the more money the banking system can create.b. The less money that households deposit, the less reserves banks have, and the less money the banking system can create.274?Chapter 16/The Monetary System2. The Fed does not control the amount that bankers choose to lend.a. The amount of money created by the banking system depends on loans being made.b. If banks choose to hold onto a greater level of reserves than required by the Fed (called excess reserves), the money supply will fall.3. Therefore, in a system of fractional-reserve banking, the amount of money in the economy depends in part on the behavior of depositors and bankers.4. Because the Fed cannot control or perfectly predict this behavior, it cannot perfectly control the money supply.D. Case Study: Bank Runs and the Money Supply1. Bank runs create a large problem under fractional-reserve banking.2. Because the bank only holds a fraction of its deposits in reserve, it will not have the funds to satisfy all of the withdrawal requests from its depositors.3. Today, deposits are guaranteed through the Federal Depository Insurance Corporation (FDIC).Chapter 16/The Monetary System?275E. The Federal Funds Rate1. Definition of federal funds rate:the short-term interest rate that banks charge one another for loans.2. When the federal funds rate rises or falls, other interest rates often move in the same direction.3. In recent years, the Fed has set a target for the federal funds rate.F. In the News: Bernanke on the Fed’s Toolbox1. During the financial crisis of 2008 and 2009, the Fed expanded reserves to help struggling banks.2. This is an article written by Fed chairman, Ben Bernanke, discussing the Fed’s options for reversing this policy once the economy recovers from this deep recession.276?Chapter 16/The Monetary SystemSOLUTIONS TO TEXT PROBLEMS:Quick Quizzes1. The three functions of money are: (1) medium of exchange; (2) unit of account; and (3) store of value. Money is a medium of exchange because money is the item people use to purchase goods and services. Money is a unit of account because it is the yardstick people use to post prices and record debts. Money is a store of value because people use it totransfer purchasing power from the present to the future.2. The primary responsibilities of the Federal Reserve are to regulate banks, to ensure thehealth of the banking system, and to control the quantity of money that is made available inthe economy. If the Fed wants to increase the supply of money, it usually does so bycreating dollars and using them to purchase government bonds from the public in thenation’s bond markets.3. Banks create money when they hold a fraction of their deposits in reserve and lend out theremainder. If the Fed wanted to use all of its tools to decrease the money supply, it would:(1) sell government bonds from its portfolio in the open market to reduce the number ofdollars in circulation; (2) increase reserve requirements to reduce the money created bybanks; (3) increase the interest rate it pays on reserves to increase the reserves banks willchoose to hold; and (4) increase the discount rate to discourage banks from borrowingreserves from the Fed.Questions for Review1. Money is different from other assets in the economy because it is the most liquid assetavailable. Other assets vary widely in their liquidity.2. Commodity money is money with intrinsic value, like gold, which can be used for purposesother than as a medium of exchange. Fiat money is money without intrinsic value; it has novalue other than its use as a medium of exchange. Our economy uses fiat money.3. Demand deposits are balances in bank accounts that depositors can access on demandsimply by writing a check or using a debit card. They should be included in the supply ofmoney because they can be used as a medium of exchange.4. The Federal Open Market Committee (FOMC) is responsible for setting monetary policy in theUnited States. The FOMC consists of the 7 members of the Federal Reserve Board ofGovernors and 5 of the 12 presidents of Federal Reserve Banks. Members of the Board ofGovernors are appointed by the president of the United States and confirmed by the U.S.Senate. The presidents of the Federal Reserve Banks are chosen by each bank’s board ofdirectors.5. If the Fed wants to increase the supply of money with open-market operations, it purchasesU.S. government bonds from the public on the open market. The purchase increases thenumber of dollars in the hands of the public, thus raising the money supply.6. Banks do not hold 100% reserves because it is more profitable to use the reserves to makeloans, which earn interest, instead of leaving the money as reserves. The amount of reservesChapter 16/The Monetary System?277 banks hold is related to the amount of money the banking system creates through the moneymultiplier. The smaller the fraction of reserves banks hold, the larger the money multiplier,because each dollar of reserves is used to create more money.7. Bank B will show a larger change in bank capital. The decrease in assets will render Bank B insolvent because its assets will fall below its liabilities, a decrease in bank capital of 140%. Bank A will suffer a large decline in bank capital (70%) but will remain solvent.8. The discount rate is the interest rate on loans that the Federal Reserve makes to banks. If the Fed raises the discount rate, fewer banks will borrow from the Fed, so both banks' reserves and the money supply will be lower.9. Reserve requirements are regulations on the minimum amount of reserves that banks must hold against deposits. An increase in reserve requirements raises the reserve ratio, lowersthe money multiplier, and decreases the money supply.10. The Fed cannot control the money supply perfectly because: (1) the Fed does not control the amount of money that households choose to hold as deposits in banks; and (2) the Fed does not control the amount that bankers choose to lend. The actions of households and banks affect the money supply in ways the Fed cannot perfectly control or predict.Quick Check Multiple Choice1. c2. c3. d4. a5. c6. aProblems and Applications1. a. A U.S. penny is considered money in the U.S. economy because it is used as a mediumof exchange to buy goods or services, it serves as a unit of account because prices instores are listed in terms of dollars and cents, and it serves as a store of value foranyone who holds it over time.b. A Mexican peso is not considered money in the U.S. economy, because it is not used as a medium of exchange, and prices are not given in terms of pesos, so it is not a unit of account. It could serve as a store of value, though.c. A Picasso painting is not considered money, because you cannot exchange it for goods or services, and prices are not given in terms of Picasso paintings. It does, however, serveas a store of value.d. A plastic credit card is similar to money, but represents deferred payment rather than immediate payment. So credit cards do not fully represent the medium of exchangefunction of money, nor are they stores of value, because they represent short-term loansrather than being an asset like currency.278?Chapter 16/The Monetary System2. When your uncle repays a $100 loan from Tenth National Bank (TNB) by writing a check from his TNB checking account, the result is a change in the assets and liabilities of both your uncle and TNB, as shown in these T-accounts:By paying off the loan, your uncle simply eliminated the outstanding loan using the assets in his checking account. Your uncle's wealth has not changed; he simply has fewer assets and fewer liabilities.3. a. Here is BSB's T-account:b. When BSB's largest depositor withdraws $10 million in cash and BSB reduces its loans outstanding to maintain the same reserve ratio, its T-account is now:c. Because BSB is cutting back on its loans, other banks will find themselves short of reserves and they may also cut back on their loans as well.d. BSB may find it difficult to cut back on its loans immediately, because it cannot force people to pay off loans. Instead, it can stop making new loans. But for a time it mightfind itself with more loans than it wants. It could try to attract additional deposits to get additional reserves, or borrow from another bank or from the Fed.4. If you take $100 that you held as currency and put it into the banking system, then the total amount of deposits in the banking system increases by $1,000, because a reserve ratio of 10% means the money multiplier is 1/0.10 = 10. Thus, the money supply increases by $900, because deposits increase by $1,000 but currency declines by $100.Chapter 16/The Monetary System?279 5. a.b. The leverage ratio = $1,000/$200 = 5.c.d. Assets decline by 9%. The bank's capital declines by 45%. The reduction in bank capitalis larger than the reduction in assets because all of the defaulted loans are covered bybank capital.6. With a required reserve ratio of 10%, the money multiplier could be as high as 1/0.10 = 10,if banks hold no excess reserves and people do not keep some additional currency. So the maximum increase in the money supply from a $10 million open-market purchase is $100 million. The smallest possible increase is $10 million if all of the money is held by banks as excess reserves.7. The money supply will expand more if the Fed buys $2,000 worth of bonds. Both depositswill lead to monetary expansion, b ut the Fed’s deposit is new money. With a 5% reserve requirement, the multiplier is 20 (1/0.05). The $2,000 from the Fed will increase the money supply by $40,000 ($2,000 x 20). The $2,000 from the cookie jar is already part of themoney supply as currency. When it is deposited the money supply increases by $38,000.Deposits increase by $40,000 ($2,000 x 20) but currency decreases by $2,000.8. a. With a required reserve ratio of 10% and no excess reserves, the money multiplier is1/0.10 = 10. If the Fed sells $1 million of government bonds, reserves will decline by $1 million and the money supply will contract by 10 × $1 million = $10 million.b. Banks might wish to hold excess reserves if they need to hold the reserves for their day-to-day operations, such as paying other banks for customers' transactions, makingchange, cashing paychecks, and so on. If banks increase excess reserves such that there is no overall change in the total reserve ratio, then the money multiplier does not change and there is no effect on the money supply.9. a. With banks holding only required reserves of 10%, the money multiplier is 1/0.10 = 10.Because reserves are $100 billion, the money supply is 10 × $100 billion = $1,000 billion or $1 trillion.b. If the required reserve ratio is raised to 20%, the money multiplier declines to 1/0.20 = 5.With reserves of $100 billion, the money supply would decline to $500 billion, a declineof $500 billion. Reserves would be unchanged.10. a. To expand the money supply, the Fed should buy bonds.280?Chapter 16/The Monetary Systemb. With a reserve requirement of 20%, the money multiplier is 1/0.20 = 5. Therefore toexpand the money supply by $40 million, the Fed should buy $40 million/5 = $8 millionworth of bonds.11. a. If people hold all money as currency, the quantity of money is $2,000.b. If people hold all money as demand deposits at banks with 100% reserves, the quantity of money is $2,000.c. If people have $1,000 in currency and $1,000 in demand deposits, the quantity of money is $2,000.d. If banks have a reserve ratio of 10%, the money multiplier is 1/0.10 = 10. So if people hold all money as demand deposits, the quantity of money is 10 × $2,000 = $20,000.e. If people hold equal amounts of currency (C) and demand deposits (D) and the money multiplier for reserves is 10, then two equations must be satisfied:(1) C = D, so that people have equal amounts of currency and demand deposits; and (2) 10 × ($2,000 –C) = D, so that the money multiplier (10) times the number of dollar bills that are not being held by people ($2,000 –C) equals the amount of demand deposits (D). Using the first equation in the second gives 10 × ($2,000 –D) = D, or $20,000 –10D = D, or $20,000 = 11 D, so D = $1,818.18. Then C = $1,818.18. The quantity of money is C + D = $3,636.36.。

曼昆宏观经济学最新英文版参考答案第29章
Chapter 29Problems and Applications1. a. A U.S. penny is money in the U.S. economy because it is used as a medium of exchange tobuy goods or services, it serves as a unit of account because prices in stores are listed interms of dollars and cents, and it serves as a store of value for anyone who holds it overtime.b. A Mexican peso is not money in the U.S. economy, because it is not used as a medium ofexchange, and prices are not given in terms of pesos, so it is not a unit of account. It couldserve as a store of value, though.c. A Picasso painting is not money, because you cannot exchange it for goods or services, andprices are not given in terms of Picasso paintings. It does, however, serve as a store ofvalue.d. A plastic credit card is similar to money, but represents deferred payment rather thanimmediate payment. So credit cards do not fully represent the medium of exchangefunction of money, nor are they really stores of value, because they represent short-termloans rather than being an asset like currency.2. For an asset to be useful as a medium of exchange, it must be widely accepted (so all transactionscan be made in terms of it), recognized easily as money (so people can perform transactions easily and quickly), divisible (so people can provide change), and difficult to counterfeit (so people will not print their own money). That is why nearly all countries use paper money with fancy designs for larger denominations and coins for smaller denominations.For an asset to be useful as a store of value, it must be something that maintains its value over time and something that can be used directly to buy goods and services or sold when money is needed.In addition to currency, financial assets (like stocks and bonds) and physical assets (like real estate and art) make good stores of value.3. a. Currency holdings jumped at the end of 1999. Many individuals were worried about Y2Kand its effect on computers. They withdrew large sums of money from banks to protectthemselves from any possible problems.b. Many answers are possible.4. When your uncle repays a $100 loan from Tenth National Bank (TNB) by writing a check from hisTNB checking account, the result is a change in the assets and liabilities of both your uncle and TNB, as shown in these T-accounts:1Chapter 29/The Monetary System 2By paying off the loan, your uncle simply eliminated the outstanding loan using the assets in his checking account. Your uncle's wealth has not changed; he simply has fewer assets and fewerliabilities.5. a. Here is BSB's T-account:b. When BSB's largest depositor withdraws $10 million in cash and BSB reduces its loansoutstanding to maintain the same reserve ratio, its T-account is now:c. Because BSB is cutting back on its loans, other banks will find themselves short of reservesand they may also cut back on their loans as well.d. BSB may find it difficult to cut back on its loans immediately, because it cannot forcepeople to pay off loans. Instead, it can stop making new loans. But for a time it might finditself with more loans than it wants. It could try to attract additional deposits to getadditional reserves, or borrow from another bank or from the Fed.6. If you take $100 that you held as currency and put it into the banking system, then the totalamount of deposits in the banking system increases by $1,000, because a reserve ratio of 10%means the money multiplier is 1/.10 = 10. Thus, the money supply increases by $900, becausedeposits increase by $1,000 but currency declines by $100.7. With a required reserve ratio of 10%, the money multiplier could be as high as 1/.10 = 10, if bankshold no excess reserves and people do not keep some additional currency. So the maximumincrease in the money supply from a $10 million open-market purchase is $100 million. Thesmallest possible increase is $10 million if all of the money is held by banks as excess reserves.8. a. If the required reserve ratio is 5%, then First National Bank's required reserves are$500,000 x .05 = $25,000. Because the bank’s total reserves are $100,000, it has excessreserves of $75,000.b. With a required reserve ratio of 5%, the money multiplier is 1/.05 = 20. If First Nationallends out its excess reserves of $75,000, the money supply will eventually increase by$75,000 x 20 = $1,500,000.Chapter 29/The Monetary System 39. a. With a required reserve ratio of 10% and no excess reserves, the money multiplier is 1/.10= 10. If the Fed sells $1 million of bonds, reserves will decline by $1 million and the moneysupply will contract by 10 x $1 million = $10 million.b. Banks might wish to hold excess reserves if they need to hold the reserves for theirday-to-day operations, such as paying other banks for customers' transactions, makingchange, cashing paychecks, and so on. If banks increase excess reserves such that there isno overall change in the total reserve ratio, then the money multiplier does not change andthere is no effect on the money supply.10. a. With banks holding only required reserves of 10%, the money multiplier is 1/.10 = 10.Because reserves are $100 billion, the money supply is 10 x $100 billion = $1,000 billion.b. If the required reserve ratio is raised to 20%, the money multiplier declines to 1/.20 = 5.With reserves of $100 billion, the money supply would decline to $500 billion, a decline of$500 billion. Reserves would be unchanged.11. a. If people hold all money as currency, the quantity of money is $2,000.b. If people hold all money as demand deposits at banks with 100% reserves, the quantity ofmoney is $2,000.c. If people have $1,000 in currency and $1,000 in demand deposits, the quantity of money is$2,000.d. If banks have a reserve ratio of 10%, the money multiplier is 1/.10 = 10. So if people holdall money as demand deposits, the quantity of money is 10 x $2,000 = $20,000.e. If people hold equal amounts of currency (C) and demand deposits (D) and the moneymultiplier for reserves is 10, then two equations must be satisfied:(1) C = D, so that people have equal amounts of currency and demand deposits; and (2)10 x ($2,000 –C) = D, so that the money multiplier (10) times the number of dollar billsthat are not being held by people ($2,000 –C) equals the amount of demand deposits (D).Using the first equation in the second gives 10 x ($2,000 –D) = D, or $20,000 – 10D = D,or $20,000 = 11 D, so D = $1,818.18. Then C = $1,818.18. The quantity of money is C +D = $3,636.36.。
曼昆宏观经济学名词解释
曼昆宏观经济学名词解释2018年中央财经大学801经济学指定参考教材发生变动，《西方经济学》由原来的高鸿业版本换成范里安的《微观经济学：现代观点》和曼昆的《宏观经济学》，同学们的复习策略也要做出相应调整，下面凯程陈老师为大家总结了曼昆的宏观经济学名词解释，以供2018考研学子使用。
第一篇国内生产总值（GDP）一个国家（地区）领土范围内，本国（地区）居民和外国居民在一定时期内所生产和提供的全部最终产品和劳务的市场价值。
含义：1.地域概念；2.市场价值概念；3.测度的是最终产品的价值，因而是流量概念；4.在一定时期内生产而非售卖掉的最终产品价值。
国民生产总值（GNP）某国国民所拥有的全部生产要素在一定时期内所生产的的最终产品和劳务的市场价值。
是一个国民概念。
GNP = GDP +来自国外的要素收入—面向国外的要素支付名义GDP与实际GDP名义GDP是用生产产品和劳务的当期价格计算的全部最终产品的市场价值；实际GDP是用从前某一年的价格作为基期价格所计算出来的当年全部最终产品的市场价值。
二者的关系：实际GDP=名义GDP/GDP平减指数国内生产总值（GDP）平减指数（帕氏）按当年价格计算的国内生产总值和按基期价格计算的国内生产总值的比率。
用公式表示为：GDP平减指数=名义GDP/实际GDP*100%优点：范围广泛，能比较准确地反映一般物价水平的变动趋向；缺点：资料较难搜集，需要对未在市场上发生交易的商品和劳务进行换算，并且可能受到价格结构因素的影响。
另外，GDP平减指数倾向于低估生活成本的增加。
消费者物价指数（CPI）（拉氏）也称消费者价格指数，是指一篮子产品与服务的价格相对于同一篮子产品与服务在某个基年的价格的比值，一般用加权平均法来编制。
用公式表示为：CPI =（一组固定商品按当期价格计算的价值、一组固定商品按基期价格计算的价值）*100优点：能及时反映消费品供给和需求的对比关系，资料容易搜集，能够迅速直接地反映影响居民生活的价格趋势；缺点：范围较窄，只包括社会最终产品中的居民消费品的这一部分，因此不足以说明全面的情况。

曼昆版本宏观经济学所有概念及重点
微观经济学(microeconomics)研究个别家庭和企业如何做出决策，以及 它们如何在市场上相互交易。宏观经济学(macroeconomics)研究整个经 济，包括通货膨胀、失业率和经济增长。 一 GDP 1 定义：国内生产总值 (gross domestic product， GDP) 是在某一既定时期一
通货膨胀率 消费者物价指数=*100
3 衡量生活费用过程中存在的问题 替代倾向 新产品的引进 无法衡量的质量变动。 4 GDP平减指数与消费者物价指数
差别1：GDP平减指数反映了国内生产的所有物品与劳务的价格，而消费物价指数 反交映了消费者购买的所有物品与劳务的价格。
差别2：消费者物价指数是固定的一篮子，只是偶尔变动；而GDP deflator 则是现期 价格，随时间变化而不断变化。
债券三个特点：期限、信用风险、税收待遇 ——股票代表企业的所有权，有权索取企业获得的利润。
股票特点：高风险、高回报 债券与股票的异同：出售股票来筹资称为“股本筹资”，而出售债券来 筹资称为“债务筹资”。股票持有者是公司的部分所有者，债券持有者 是公司的债权人。 两者都可获益，也都有风险。与债券相比，股票有 潜在的高收益，同时也具有高风险。 ——当企业利润丰厚时，股票持有者可以分得较多红利，债券持有者只 是固定的利息。
物质资本（简称资本）：用于生产物品与劳务的设备和建 筑物存量。 人力资本：工人通过教育、培训和经验而获得的知识和技 能。 自然资源 技术知识：懂得生产物品与劳务的最好方法。 三 怎么保证一国生活水平的提高
储蓄和投资：提高储蓄率，将储存的钱进行投 资，必然减少现期劳务的消费，但是会增加未来 生产率。 益递减：在工人已经用大量资本存量生产物品与劳务时，给他们增加的一单位资本 所提高的生产率是微小的。 追赶效应：在其他条件相同的情况下，如果一国开始时较 穷，它就更易实现迅速增长。这是由于资本的收益 递减效应引起的。 所以，储蓄率的增加引起的高增长只是暂时的。 吸引外资：吸引外资，可以增加本国的资本存量，进而增 加GDP，国际组织为世界银行。 教育和健康营养：良好的教育、健康的身体，有利于提高 生产率，进而提高生活水平和收入。 人口增长：稀释了自然资源；稀释了资本存量；促进了技 术进步。 产权和政治稳定 自由贸易：内向型政策和外向型政策的选择，穷国一般选 择前者保护自己被发达国家侵蚀。 研究与开发 四 长期增长的重要性 保持经济的长期增长才是最终的目标。
