Introduction Barter • The exchange of one good for another, without the use of

Introduction 1. What is the key problem with barter exchange? • To function effectively, barter requires a double coincidence of each party to the exchange wanting precisely what the other has to offer. A double coincidence of wants is difficult to achieve. © 2005 Gottheil - Principles of Economics, 4 e 5

Fluffy Rabbits and Gresham’s Law Suppose more valuable silver quarters and less valuable copper-nickel quarters freely circulate together in the economy. What would happen over time? • People would keep the more valuable silver quarters, and eventually only the less valuable copper-nickel quarters would freely circulate. © 2005 Gottheil - Principles of Economics, 4 e 13

Fluffy Rabbits and Gresham’s Law Suppose more valuable silver quarters and less valuable copper-nickel quarters freely circulate together in the economy. What would happen over time? • Sir Thomas Gresham, a 16 th century merchant to the English crown, observed that bad money drives out good. © 2005 Gottheil - Principles of Economics, 4 e 14

Money in a Modern Economy Liquidity • The degree to which an asset can

Money in a Modern Economy Liquidity is what distinguishes money from any other asset form. • Some assets are relatively liquid, and can serve as money. • Most assets are highly illiquid and thus far removed from serving as money. © 2005 Gottheil - Principles of Economics, 4 e 17

Money in a Modern Economy Money supply • Typically, M 1 money. The supply

Money in a Modern Economy M 1 Money supply • The supply of the most immediate form of money. It includes currency, demand deposits, and traveler’s checks. © 2005 Gottheil - Principles of Economics, 4 e 19

Money in a Modern Economy M 2 Money supply • M 1 money plus less-immediate forms of money, such as savings accounts, money market mutual fund accounts, money market deposit accounts, repurchase agreements, and small-denomination time deposits. © 2005 Gottheil - Principles of Economics, 4 e 20

Money in a Modern Economy M 3 Money supply • M 2 money plus

Explaining the Impressive Growth of M 2 Money What caused the impressive growth of M 2 money? • Deregulation of the banking industry led to a large increase in money market accounts (mutual funds and deposit accounts), and increased the liquidity of savings accounts. © 2005 Gottheil - Principles of Economics, 4 e 22

Money in a Modern Economy Are credit cards a form of money? • No. They may be accepted as readily as money by stores, but credit cards are loans that must be repaid. © 2005 Gottheil - Principles of Economics, 4 e 24

Exhibit 2: Growth of the Money Supply: 1970 -2003 1. True or false: M 1 grew more slowly than M 2 and M 3 between 1970 and 2003. • True. Deregulation of the banking industry increased elements of M 2, which in turn increased M 3. © 2005 Gottheil - Principles of Economics, 4 e 30

Exhibit 2: Growth of the Money Supply: 1970 -2003 1. True or false: By 1992, M 2 became larger than M 3. • False. That cannot occur because M 3 includes M 2 plus other types of money. © 2005 Gottheil - Principles of Economics, 4 e 31

The Quantity Theory of Money Velocity of money • The average number of times

The Quantity Theory of Money Equation of exchange • MV = PQ. The quantity of money times its velocity equals the quantity of goods and services produced times their prices. © 2005 Gottheil - Principles of Economics, 4 e 53

The Quantity Theory of Money The classical view: • Real GDP (Q in the equation of exchange) depends on the amount of resources in the economy, which are fixed. • Prices are flexible. • Velocity is fixed. © 2005 Gottheil - Principles of Economics, 4 e 54

The Quantity Theory of Money The classical view: • Since Q and V are fixed, while P is flexible, the classical view holds that there is a direct relationship between M and P. © 2005 Gottheil - Principles of Economics, 4 e 55

The Quantity Theory of Money Quantity theory of money • P = MV/Q. The

The Quantity Theory of Money Monetarists attempted to rescue the classical view from evidence showing that M 1 velocity is not constant. They argue that if velocity is stable and predictable, and if Q is at fullemployment GDP, then the direct relationship between M and P remains intact. © 2005 Gottheil - Principles of Economics, 4 e 57

EXHIBIT 3 HISTORICAL RECORD OF MONEY VELOCITY 58 © 2005

Exhibit 3: Historical Record of Money Velocity How might the use of credit cards have explained the change in M 1 velocity from the 1950 s to the 1980 s? • Increased use of credit cards during this period allowed people to buy more goods and services with less cash and lower demand deposit balances relative to nominal GDP. 59 Gottheil - Principles of Economics, © 2005 4 e

The Quantity Theory of Money Keynesians reject the monetarist’s idea that V is either stable or predictable, and that Q always reflects full-employment GDP. In this case, changes in M will affect more than just P—they may also change Q. © 2005 Gottheil - Principles of Economics, 4 e 60

The Demand for Money Transactions demand for money • The quantity of money demanded by households and businesses to transact their buying and selling of goods and services. © 2005 Gottheil - Principles of Economics, 4 e 61

The Demand for Money The classical view is that the transactions demand for money is the only motive for demanding money. If P or Q rises, the transactions demand for money will also rise. © 2005 Gottheil - Principles of Economics, 4 e 62

The Demand for Money The Keynesian view is that in addition to the transactions demand for money, there is also a precautionary motive and a speculative motive for demanding money. © 2005 Gottheil - Principles of Economics, 4 e 63

EXHIBIT 4 © 2005 THE SPECULATIVE DEMAND FOR MONEY Gottheil - Principles of Economics,

Exhibit 4: The Speculative Demand for Money According to the speculative motive, why does the quantity of money demanded increase as interest rates decrease? • People shift out of interest-paying accounts into holding money because the opportunity cost of holding money has fallen. © 2005 Gottheil - Principles of Economics, 4 e 65

Exhibit 4: The Speculative Demand for Money According to the speculative motive, why does the quantity of money demanded increase as interest rates decrease? • This reduces the cost of speculatively having money immediately available to take advantage of unforeseen good purchasing opportunities that may suddenly arise. © 2005 Gottheil - Principles of Economics, 4 e 66

EXHIBIT 5 A MONEY AFFECTS REAL GDP 67 © 2005

EXHIBIT 5 B MONEY AFFECTS REAL GDP 68 © 2005

EXHIBIT 5 C MONEY AFFECTS REAL GDP 69 © 2005

Exhibit 5: Money Affects Real GDP According to the Keynesian view, how does a change in the money supply affect real GDP? • An increase in the money supply reduces interest rates. • Lower interest rates increase investment spending. • Increased investment spending increases aggregate demand. © 2005 Gottheil - Principles of Economics, 4 e 70

The Demand for Money What is the shape of the aggregate supply curve when a change in the money supply affects real GDP but not the price level? • The segment of the aggregate supply curve over which aggregate demand shifts is horizontal. © 2005 Gottheil - Principles of Economics, 4 e 71

The Demand for Money How do classical economists and monetarists see the shape of the aggregate supply curve? • The segment of the aggregate supply curve over which aggregate demand shifts is vertical, and occurs at the fullemployment level of real GDP. Thus only prices change, not real GDP. © 2005 Gottheil - Principles of Economics, 4 e 72
