1、Lecture Notes for Chapter 6 ofMACROECONOMICS:An IntroductionMoney, Banks, andThe Federal ReserveCopyright 1999 - 2008 by Charles R. Nelson02/15/08In this chapter we will discuss-What money is.What money does.What kinds there are.How much there is.How it is created.What the Federal Reserve is.How the

2、 Fed controls money.What is money?That which is accepted in paymentfor goods & services to settle debts.It is an asset, a special kind of assetExamples:a $20 dollar bill,a personal check.We do not meanIncome: “the average programmer makes $150,000 per year.”Wealth: “Bill Gates is worth $90 billion.”

3、Debt: “US government owes $5 trillion”These are examples of using money as a measuring stick, a unit of account.The money you hold consists ofCurrency, dollar bills and coins, andthe balance in your checking account.Three important uses of money:1. The medium of exchange.Money avoids the costly and

4、time consuming process of barter.Money is a fundamental invention like the wheel.No doubt in use on other planets!The oil that lubricates the wheels of commerce.2. The unit of accountGives us a yardstick of value.Allows comparison of the costs and values of very different things,say the cost of a CD

5、 and theater ticket.We can compare incomes in dollars.Not so easy in a barter economy!3. Money is a store of value.A reserve of purchasing power.The most liquid of all assets.How does inflation affect this use?Steady predictable inflation?Highly variable inflation?Assets vary in their liquidity -A h

6、ouse is valuable but not liquid.GE stock can be turned into cash in a few days, but value is uncertain.A T bond is very liquid; andprice fluctuates less than a stock.A T bill is very, very liquid; quickly converted to cash, very stable in price.T bills are often referred to as cash equivalentsOn the

7、 balance sheets of firms“this mutual fund has 40% in cash“cash” means T bills or similar.T bills and similar corporate securities are called “the money market.”“Money Market Mutual Funds” But a T bill is not money! Why?Not all money is equally liquid A $100 bill is more liquid than a T bill,but not

8、as liquid as a $20 bill. Try giving a cab driver a $100 bill at1 am in New York City.The U.S. $20 is surely the most liquid of all assets on earth.It is also the most counterfeited!Kinds of moneyCommodity money Has intrinsic value.Examples:metals such as copper, silver and goldcigarettes (in prisone

9、r-of-war camps)cattle.What qualities make a good commodity money?Durability.Valuable in small sizes and weights.Divisible into varying sizes.Easily verified as genuine.Stable in value.Gold does very well on all five points.Almost all the gold that people have ever used is still in use!CoinsStamped b

10、y the government Standardized weight Immediately recognized value.Earliest minted by the Greeks 600BC.But governments often cheated,diluting the gold content with cheaper metalOld, valuable coins quickly disappeared.Greshams Law: bad money drives out the good.Sandwich coins introduced in 1960s,silve

11、r coins soon disappeared.Illegal to sell them, but many did.Coins minted today are token coins, metals they contain have little value.Paper moneyInvented in China,to Europe with Marco Polo 1200.Claim on gold or silverfrom government or a bank.All paper money and coins today are . .Fiat MoneyOf value

12、 only because it is legal tender.Law says seller must accept itin payment for goods and services,& lenders in payment of debt.We accept it since know others will.All the paper money and coinsin the world today are fiat money!Paper money and coins as currency.The Mint makes a mint!The government has

13、a license to print money!Profit is difference between value of the coin or bill and cost of manufacture.Called Seigniorage.Why are small units coins and large denominations paper bills?Bank MoneyChecks.Personal checks are not legal tenderand are not as liquid as currency.Money Market Mutual Fund che

14、cksSavings account transfers by phone.Savings accounts & other very liquid but not checkable are near money.How much money is there?Means: “What is the total of currency, checkable deposits, and savings accounts?”Does not mean: “What is the total of all assets?”“What is total income?”Money here mean

15、s medium of exchange, not a yardstick of value.Quantity of Money in 2008:Currency = $ 800 billion!plus checkable deposits = M1 = $1,400bplus MMMF and savings = M2 = $7,500b$2,500 in currency per American! How much do you carry?Where is it all?Japanese carry more currency (Yen) than Americans do (dol

16、lars). Why?About 40% is abroad.Where local currency is unstable,where inflation is rampant.Argentina adopted US$ as reserve.Stashed by corrupt regimes $600 Million in $100 bills in Iraq.Also used to hide income from illegal businesses, and to avoid tax.Are Credit Cards Money?Plastic Money is really

17、a short-term loan.The monthly bill is still settled by payment of money.Will plastic ever replace money?Credit cards have not replaced money, nor are money holdings smaller!A Brief History of BankingBanks are as old as civilization itself.In Middle Ages usury was banned. Banking revived in Italy dur

18、ing the Renaissance; banco means bench. The Medici family established their bank in Florence in the 1300s and accumulated great wealth and power, making Florence a center of the arts.Fractional reserve banking invented in England 1600.Goldsmith had a vault for keeping valuables, so offered safekeepi

19、ng.Gold and silver coins worth say 100 deposited, receipts or notes given.Notes only occasionally redeemed.Goldsmiths reserves, the coins in the vault, were equal to deposits, 100.why not lend out notes, say 200?The Goldsmiths Balance Sheet Assets LiabilitiesReserves 100Loans200Notes300Total300Total

20、300Amazing!Goldsmith has created 200 from thin airThat is fractional reserve banking.As long as borrowers continued to make payment on their loans, all was well. If loans were not repaid, the bank could not redeem its notes, and the bank failed. A bank holds illiquid assets (loans) while issuing liq

21、uid liabilities (notes).A Run on the Bank:The bank would fail if holders of its notes all demanded their coins at once.A run on the bank has always been a threat to any fractional reserve bank.Bank runs were common in 1800s, during the Great Depression of the 30s thousands of banks failed in the U.

22、S.Banking in AmericaThe Coinage Act of 1792 established the dollar as the monetary unit for the US.amount of silver or gold in coins fixed.From 1834 to 1933 gold was $20.67/ozExcept for Civil War greenbacks, paper money was issued by banks.Bank reserves were silver and goldThe era of wildcat banking

23、1836 to 1864 new banks on frontier.notes of hundreds of banks circulated, all claiming to be good as gold.banks notes promised to pay in silver or gold, but exceeded banks reserves.Magic of fractional reserve banking!The Gold StandardGold was the more important of the two monetary metals and the sys

24、tem became known as the gold standard.That did not mean that all the money was backed by gold,but it did tie the quantity of money to the relatively fixed supply of gold.A modern banks balance sheet:AssetsLiabilitiesReserves$100 Deposits $1,000Loans 900Total $1,000 Total $1,000How it works:Reserves

25、include currency in the vault and deposits at the Federal Reserve.The remaining $900 has been lent out.Bank earns interest on loanspays interest on some deposits and provides services such as drive through and make a profit for shareholders.The Federal Reserve19th century Americans viewed central ba

26、nk as excessive concentration of power.Two early central banks were disbanded.The Bank of England, originally a private bank, was model for modern central banks.Our Fed was created in 1913 to stabilize the monetary system, be the banks bank.Did the Fed stabilize banks?Ironically, the worst bank fail

27、ures occurred in 1929 under Fed supervision.One factor: 12 district banks decentralized authority, which lead to inaction.Fed was reorganized in 1930s,control centralized in Wash DC under theBoard of Governorsas critics feared!The Fed today -The “monetary authority”empowered to issue U.S. currency.7

28、 Governors are appointed by the President, confirmed by the Senate,serve for 14 years.Chairperson is a governor, appointed by the President to 4 year term as Chair.Ben Bernanke is Chair now.The FOMC makes policyFederal Open Market CommitteeIt meets 8 times a yearMeetings are secretMembers: all 7 gov

29、ernorsplus 5 district bank presidents.President of the NY Fed always votes,represents NYC as center of finance.The Chairperson of the FedPresides over meetings of the FOMC, a source of considerable power.Paul Volcker appointed by Pres. Carter to defeat inflation.Alan Greenspan appointed 1986. Presid

30、ed for 20 years of prosperity and low inflation, becoming an icon.Succeeded by Ben Bernanke in 2006.The Secrets of the “Temple”Fed building looks like a Roman templeChairs office is the inner sanctumSecrecy of its inner workings has always been a source of it powerRecently more open due to pressure

31、from Congress.FOMC now announces decisions immediately after meetingMain functions of the Fed are:1. Ensure growth in money and credit sufficient toAchieve long term growth, a high level of employment, and reasonable price stability.How? By using Monetary Policy.“That means managing supply of money

32、and level of interest rates.2. Supervise banks and bank holding companiesBank mergers, the soundness of banks, consumer protection,the scope of banks activities.When a bank gets into trouble, the Fed usually arranges a shotgun marriage with a stronger bank.3. Be the “l(fā)ender of last resort” Fed is th

33、e banks bank. It lends to them in case of national crisis or bank failure.Since the Fed employs 247 economists, it is also known as the employer of last resort.Federal Deposit Insurance Corp.FDIC founded in response to bank failures in the Depression of the 1930s.to protect depositors and stabilize

34、the banking systemFSLIC did the same for Savings and LoansBoth created a “moral hazard”a weak bank or S&L could attract deposits on the guarantee of the U.S. Govt.Banking until 1980.Banks protected by regulation that restricted competition. Generally operated in only one state.“Savings and Loans” we

35、re home mortgage lenders, typically small and local, offered only savings accounts.Banks and S&Ls paid low interest to depositors under “Regulation Q”.Banking was a 3-6-3 business:pay depositors 3%, charge 6% for loans, be on the golf course by 3pm!Today there are only banks and competition is feroc

36、ious.Large banks operate nationally.What made the system change?The Savings and Loan DebacleIn 1970s inflation devastated value of mortgages, an S&Ls main asset.Monetary Control Act of 1980 allowed S&Ls to compete with banks,Placed them under Fed control,Raised deposit insurance limitsGarn-St.Germai

37、n Act of 1982 erased distinctions between banks and S&Ls.By 1980 inflation and high interest rates had.Devastated value of mortgage assets, raised cost of borrowed fundsMany S&Ls engaged in risky lending.They bet the bank, and often lost it!Texas S&Ls alone “ate the FSLIC.”Resulting bail out cost ta

38、xpayers many billions.How does banking look now?We have only banks.Deposit insurance protection limited to $100,000 per depositor.Banking is national and even international.Emergence of giant national banks; B of A has almost 10% of all deposits.Internet is making lending highly competitive!How the

39、Fed Controls the Quantity of MoneyThrough open market operationsit can add or drain bank reserves.Fed buys or sells Treasury securities.Pays with money it creates by fiat.Boosted by “Money multiplication.”Elements in the process:Banks hold some reserves. Required as a fraction of depositsExcess rese

40、rves kept to a minimumA bank that is short of reserves cango to the “discount window” and borrow at the “discount rate” orborrow from other banks in “fed funds market” at the “fed funds rate.”A Fed open market operation:Fed prints up bills worth $1,000,buys a T bill for $1000 from someone.How can it

41、 do that?It has the authority to print money!Seller deposits the $1000 in their bank.That bank now has $1000 in new deposits.If the reserve requirement is 10%, it now has excess reserves of $900.Why not loan out that $900 to Joe Smith?Joe remodels his house, the contractor puts the $900 in his bank

42、account.Now that bank has $900 in new deposits and $810 in excess reserves.This process continues until the $1,000 of new reserves is completely used up as reserves supporting new deposits:Here is how it plays out:To calculate changes we can use a spreadsheet on the computeruse of the result from co

43、llege algebra that for any fraction x, 1+x+x2+x3+ . = 1/(1-x)At each stage, the next quantity is .90 of the previous quantityTotal New Deposits = $1,000(1 + .90 + .902 + .903 + .) = $1,000(1/1-.90) = $1,000(1/.10) = $1,00010 = $10,000Total Required reserves = $100(1 + .90 + .902 + .903 + .) = $10010 = $1,000Total Loans = $900(1 + .90 + .902 + .903 + .) = $90010 = $9,000Expansion continues
