2. 13-2 The Uses of Money Barter is the direct exchange of one good for another, without the use of money. LO-1

3. 13-3 The three functions of money (anything serving these purposes is money): –Medium of exchange–is accepted as payment for goods and services (and debts). –Store of value–can be held for future purchases. –Standard of value–serves as a yardstick for measuring the prices of goods and services. The Uses of Money LO-1

4. 13-4 Cash versus Money The concept of money includes more than dollar bills and coins. Checking accounts can and do perform the same market function as cash. Money is anything generally accepted as a medium of exchange. LO-1

5. 13-5 Transactions Accounts A transactions account is a bank account that permits direct payments to a third party (e.g., with a check). The balance in your transactions account substitutes for cash and, therefore, is a form of money. LO-1

6. 13-6 Basic Money Supply The basic money supply is typically referred to by the abbreviation M1. M1 is currency held by the public, plus balances in transactions accounts. Cash is only part of the money supply; most money consists of balances in transactions accounts. LO-2

7. 13-7 Figure 13.1

8. 13-8 Credit cards are another popular medium of exchange. Credit cards are not a form of money. They are simply a payment service, not a store of value. Basic Money Supply LO-2

9. 13-9 Composition of the Basic Money Supply (M1) The money supply (M1) includes: –Currency in circulation –Transaction-account balances –Traveler’s checks LO-2

10. 13-10 Near Money Savings accounts Certificates of deposit (CDs) Money-market mutual funds These represent additional measures of the money supply (M2, M3, etc.). We will limit our discussion to M1, the basic money supply. LO-2

11. 13-11 Cashless Society? We’re keeping a smaller percentage of the money supply as cash as we: Rely more on credit cards for purchases. Receive direct deposit for paychecks. Use more checks instead of cash. Rely more on debit cards for transactions. Complete many transactions via direct wire transfer of money. LO-2

12. 13-12 Creation of Money The Bureau of Engraving and Printing and the U.S. Mint play only a minor role in creating money. Most of what we call money is bank balances, not cash. LO-3

13. 13-13 Deposit Creation In making a loan, a bank effectively creates money, because transactions- account balances are counted as part of the money supply. Banks create transactions-account balances by making loans. Deposit creation–the creation of transactions deposits by bank lending. LO-3

14. 13-14 A Monopoly Bank To keep things simple, assume one bank in a town, and no one regulates bank behavior. You deposit $100 from your piggy bank into the monopoly bank and receive a new checking account. When you deposit cash or coins in a bank, you are changing the composition of the money supply, not its size. LO-3

15. 13-15 An Initial Loan The monopoly bank loans $100 to Campus Radio. It deposits $100 into Campus Radio’s checking account. The loan is accomplished by a simple bookkeeping entry. LO-3

16. 13-16 An Initial Loan Money has been created because the checking account is considered to be money. Total bank reserves have remained unchanged: –Bank reserves are assets held by a bank to fulfill its deposit obligations. LO-3

17. 13-17 Using the Loan The money supply does not contract when Campus Radio spends the $100. The ownership of the deposit changes. LO-3

18. 13-18 Fractional Reserves Bank reserves are only a fraction of total transactions deposits. The reserve ratio is the ratio of a bank’s reserves to its total transactions deposits: LO-3

19. 13-19 The ability of a monopoly bank to hold fractional reserves results from two facts: –People use checks for most transactions. –There is no other bank. Fractional Reserves LO-3

20. 13-20 Required Reserves The minimum reserve requirement directly limits deposit-creation possibilities. LO-3

21. 13-21 Reserve Requirements Required reserves are equal to the required reserve ratio times transactions deposits: LO-3

22. 13-22 If a bank could create money at will, it would have a lot of control over aggregate demand. In reality, no private bank has that much power. The power to create money resides in the banking system, not in any single bank. Reserve Requirements LO-3

23. 13-23 The Federal Reserve System requires banks to maintain some minimum reserve ratio. Required reserves are the minimum amount of reserves a bank is required to hold by government regulation. Reserve Requirements LO-3

24. 13-24 Excess Reserves Excess reserves are bank reserves in excess of required reserves: Excess Reserves = Total Reserves – Required Reserves LO-3

25. 13-25 The ability of banks to make loans depends on access to excess reserves. So long as a bank has excess reserves, it can make additional loans. If a bank currently has $100 in reserves and is required to hold $75, it can lend out the excess $25. Excess Reserves LO-3

26. 13-26 A Multibank World In reality there is more than one bank in town. The key issue is not how much excess reserves any specific bank holds but how much excess reserves exist in the entire banking system. LO-3

27. 13-27 The Money Multiplier Excess reserves are the source of bank lending authority. The cumulative amount of new loans is determined by the money multiplier. LO-4

28. 13-28 The money multiplier is the number of deposit (loan) dollars that the banking system can create from $1 of excess reserves: The Money Multiplier LO-4

29. 13-29 The Money Multiplier Process An initial deposit of $100 is made at University Bank. University Bank keeps $75 (75% of the $100 new deposit) on reserve and loans out $25, which is deposited in Bank Two. Bank Two keeps 75% of the new deposit on reserve ($18.75) and loans out $6.25 LO-4

30. 13-30 Bank Three keeps 75% of the new deposit on reserve ($4.69) and loans out $1.56. This process continues until all excess reserves have disappeared. The Money Multiplier Process LO-4

31. 13-31 Figure 13.2

32. 13-32 Limits to Deposit Creation The potential of the money multiplier to create loans is summarized by the equation: LO-4

33. 13-33 If the required reserve ratio =.75: –The multiplier = 1.33 If the banking system has $25 in excess reserves: –Potential deposit creation is $25 x 1.33 = $33.25 Limits to Deposit Creation LO-4

34. 13-34 Excess Reserves as Lending Power Each bank may lend an amount equal to its excess reserves and no more. The entire banking system can increase the volume of loans by the total amount of excess reserves in the banking system multiplied by the money multiplier. LO-4

35. 13-35 The Macro Role of Banks Banks can create money. Since virtually all market transactions involve the use of money, banks must have some influence on macro outcomes. LO-5

36. 13-36 Figure 13.3

37. 13-37 Financing Aggregate Demand Banks perform two essential functions: –Banks transfer money from savers to spenders by lending funds (reserves) held on deposit. –The banking system creates additional money by making loans in excess of total reserves. LO-5

38. 13-38 Constraints on Money Creation There are four major constraints on banks’ lending ability: –Bank Deposits –Willing Borrowers –Willing Lenders –Government Regulation LO-5

39. 13-39 Bank Deposits Bank reserves will be lower if people prefer to hold cash rather than make deposits in their transactions accounts. LO-5

40. 13-40 Willing Borrowers and Lenders If consumers, businesses, and governments don’t want to borrow, fewer deposits will be created. Banks may not be willing to satisfy credit demands, choosing instead to hold excess reserves. LO-5

41. 13-41 Government Regulation The Federal Reserve regulates bank lending practices. LO-5

42. 13-42 Digital Money The most common forms of money used in brick-and-mortar malls cannot be used as a medium of exchange in electronic malls. LO-5

43. 13-43 Credit Cards Almost all Internet purchases are completed with a credit card. Dependence on credit cards limits the potential of e-commerce because of: –Security issues such as credit card number theft. –Use and sale of credit card databases by e-retailers for undisclosed purposes. LO-5

44. 13-44 E-Payments Some companies offer a quasi-banking service by storing purchasing power that consumers and e-retailers can access. Consumers must “deposit” e-cash with credit card advances. LO-5

45. 13-45 Speed of Spending Consumers still need cash and checking-account balances to pay for their e-purchases. Virtual malls allow consumers to spend money balances faster, thereby boosting aggregate demand. LO-5
