6 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 6 of 23 The Demand for Money transaction motive The main reason that people hold money—to buy things. The Transaction Motive When we speak of the demand for money, we are concerned with how much of your financial assets you want to hold in the form of money, which does not earn interest, versus how much you want to hold in interest-bearing securities, such as bonds.

The Transaction Motive

9 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 9 of 23 The Demand for Money The Transaction Motive Jim could decide to deposit his entire paycheck ($1,200) into his checking account at the start of the month and run his balance down to zero by the end of the month. In this case, his average balance would be $600.  FIGURE 11.2 Jim’s Monthly Checking Account Balances: Strategy 1

10 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 10 of 23 The Demand for Money The Transaction Motive Jim could also choose to put half of his paycheck into his checking account and buy a bond with the other half of his income. At midmonth, Jim would sell the bond and deposit the $600 into his checking account to pay the second half of the month’s bills. Following this strategy, Jim’s average money holdings would be $300.  FIGURE 11.3 Jim’s Monthly Checking Account Balances: Strategy 2

11 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 11 of 23 The Demand for Money The Transaction Motive The quantity of money demanded (the amount of money households and firms want to hold) is a function of the interest rate. Because the interest rate is the opportunity cost of holding money balances, increases in the interest rate reduce the quantity of money that firms and households want to hold and decreases in the interest rate increase the quantity of money that firms and households want to hold.  FIGURE 11.4 The Demand Curve for Money Balances

12 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 12 of 23 The Demand for Money The Speculation Motive speculation motive One reason for holding bonds instead of money: Because the market price of interest-bearing bonds is inversely related to the interest rate, investors may want to hold bonds when interest rates are high with the hope of selling them when interest rates fall.

13 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 13 of 23 The Demand for Money The Total Demand for Money The total quantity of money demanded in the economy is the sum of the demand for checking account balances and cash by both households and firms. At any given moment, there is a demand for money—for cash and checking account balances. Although households and firms need to hold balances for everyday transactions, their demand has a limit. For both households and firms, the quantity of money demanded at any moment depends on the opportunity cost of holding money, a cost determined by the interest rate.

Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 14 of 23 The Demand for Money The Total Demand for Money ATMs and the Demandfor Money Italy makes a great case study of the effects of the spread of ATMs on the demand for money. In Italy, virtually all checking accounts pay interest. What doesn’t pay interest is cash. In other words, in Italy there is an interest cost to carrying cash instead of depositing the cash in a checking account.

15 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 15 of 23 The Demand for Money The Effects of Income and the Price Level on the Demand for Money An increase in Y means that there is more economic activity. Firms are producing and selling more, and households are earning more income and buying more. There are more transactions, for which money is needed. As a result, both firms and households are likely to increase their holdings of money balances at a given interest rate.  FIGURE 11.5 An Increase in Aggregate Output (Income) (Y) Will Shift the Money Demand Curve to the Right

16 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 16 of 23 The Demand for Money The Effects of Income and the Price Level on the Demand for Money TABLE 11.1 Determinants of Money Demand 1.The interest rate: r (The quantity of money demanded is a negative function of the interest rate.) 2.The dollar volume of transactions a. Aggregate output (income): Y (An increase in Y shifts the money demand curve to the right.) b. The price level: P (An increase in P shifts the money demand curve to the right.) The amount of money needed by firms and households to facilitate their day-to-day transactions also depends on the average dollar amount of each transaction. In turn, the average amount of each transaction depends on prices, or instead, on the price level.

17 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 17 of 23 The Equilibrium Interest Rate We are now in a position to consider one of the key questions in macroeconomics: How is the interest rate determined in the economy? The point at which the quantity of money demanded equals the quantity of money supplied determines the equilibrium interest rate in the economy.

18 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 18 of 23 The Equilibrium Interest Rate Supply and Demand in the Money Market Equilibrium exists in the money market when the supply of money is equal to the demand for money and thus when the supply of bonds is equal to the demand for bonds. At r 0 the price of bonds would be bid up (and thus the interest rate down), and at r 1 the price of bonds would be bid down (and thus the interest rate up).  FIGURE 11.6 Adjustments in the Money Market

23 CHAPTER 11 Money Demand and the Equilibrium Interest Rate © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 23 of 23 THE VARIOUS INTEREST RATES IN THE U.S. ECONOMY A P P E N D I X A THE TERM STRUCTURE OF INTEREST RATES The term structure of interest rates is the relationship among the interest rates offered on securities of different maturities. According to a theory called the expectations theory of the term structure of interest rates, the 2- year rate is equal to the average of the current 1- year rate and the 1-year rate expected a year from now. People’s expectations of higher future short-term interest rates are likely to increase. These expectations will then be reflected in current long- term interest rates.
