26. ©2012 The McGraw-Hill Companies, All Rights Reserved 26 Bank Reserves Cash in a bank's vault is not part of the money supply  Unavailable for payments  Bank deposits available for use in transactions are part of the money supply  Depositing a $100 bill in your checking account does not change the money supply Bankers realize that inflows and outflows from vaults leave some guilders unused  Only 10% of deposits are needed for transactions  90% can be lent to borrowers for a fee -- interest

27. ©2012 The McGraw-Hill Companies, All Rights Reserved 27 Consolidated Bank Balance Sheet – Part 2 Currency held in the vault is the bank reserves The reserve – deposit ratio is bank reserves divided by total deposits Fractional reserve banking system holds less bank reserves than deposits  The reserve – deposit ratio is less than 100% AssetsLiabilities Currency100,000 gDeposits1,000,000 g Loans900,000 g

31. ©2012 The McGraw-Hill Companies, All Rights Reserved 31 Money Multiplier We see that the existence of a fractional-reserve banking system has multiplied the money supply by a factor of 10, relative to the economy with no banks or the economy with 100 percent reserve banking. This can be expressed with the money multiplier (MM): MM = 1/R = 1/0.10 = 10 where R represents the reserve-deposit ratio of 10 percent.

33. ©2012 The McGraw-Hill Companies, All Rights Reserved 33 Money Supply with Currency and Deposits Marhaba residents hold 500,000 guilders as currency  Deposit 500,000 guilders in the banks  Reserve-deposit ratio = 10%  Bank deposits = 500,000 / 0.10 = 5,000,000 guilders  Money supply = 500,000 cash + 5,000,000 deposits = 5,500,000 guilders Money supply = Currency held by public + Bank reserves Desired reserve – deposit ratio

34. ©2012 The McGraw-Hill Companies, All Rights Reserved 34 Central Banks, The Money Supply, and Prices Central banks in general have two main responsibilities:  Responsible for monetary policy, which means that a country’s central bank determines how much money circulates in the economy  Oversight and regulation of financial markets In particular, central banks play important roles during periods of crisis in financial markets

35. ©2012 The McGraw-Hill Companies, All Rights Reserved 35 Controlling The Money Supply with Open- Market Operations Monetary policy is deciding and managing the size of the nation's money supply  Money supply is controlled indirectly  Open-market purchase of government bonds from the pubic by the central bank increases bank reserves and the money supply  Open-market sale of government bonds by the central bank to the public decreases reserves and money supply

36. ©2012 The McGraw-Hill Companies, All Rights Reserved 36 Open Market Operations When the Central Bank purchases a bond from the public  The central bank pays bond holder with new money  Receipts are deposited and this leads to a multiple expansion of the money supply When the central bank sells a bond to the public  Bondholder pays with checking funds  Bank reserves decrease and this leads to a multiple contraction of the money supply

37. ©2012 The McGraw-Hill Companies, All Rights Reserved 37 Increasing the Money Supply An economy has 1,000 dirhams in currency and bank reserves of 200 dirhams  Reserve-deposit ratio = 0.2  Money supply = 1,000 + (200 / 0.2) = 2,000 dirhams Central bank pays 100 dirhams for a bond held by the public  Assume that all 100 dirhams are deposited  Money supply = 1,000 + (300/ 0.2) = 2,500 dirhams  100 dirham increase in reserves leads to a 500 dirham increase in the money supply

38. ©2012 The McGraw-Hill Companies, All Rights Reserved 38 Money and Prices In the long run, the amount of money circulating and the level of prices are closely linked  Sustained high inflation rates occur with a comparably high growth rate of the money supply

39. ©2012 The McGraw-Hill Companies, All Rights Reserved 39 Velocity of Money (V) Velocity is the speed money changes hands in transaction for final goods and services Nominal GDP is the price level (P) times real GDP (Y) M is the money supply Velocity = Nominal GDP Money supply V = (P) (Y) M

40. ©2012 The McGraw-Hill Companies, All Rights Reserved 40 Velocity of M1 and M2, 2008  Except for Morocco, velocity of money of M1 is substantially higher than that of M2.  New technologies have increased velocity over time.

41. ©2012 The McGraw-Hill Companies, All Rights Reserved 41 Money and Inflation in the Long Run Quantity equation states (M) (V) = (P) (Y)  Restatement of the velocity definition The quantity equation relates the money supply to price levels  Suppose velocity and real GDP are constant The quantity equation becomes  An increase in the money supply by a given percentage would increase prices by the same percentage V and Y, respectively M V = P Y

42. ©2012 The McGraw-Hill Companies, All Rights Reserved 42 Approximating a Percentage Change M V = P Y % change in (M V) = % change in (P Y) The percentage change in a product is the sum of the percentage changes in each variable Consequently % change in M + % change in V ≈ % change in P + % change in Y If the M grows 4% per year and V grows 1% per year, nominal GDP (P Y) grows approximately 5% per year  If Y grows 3% per year, then the percentage change in price is approximately 2% per year
