5. The Money Market • The previous chapter covered the money supply and how money is created. • This chapter covers the demand for money. • We need money supply and demand so we can find out the equilibrium interest rate. • The money market is the market for money where the amount supplied and the amount demanded meet to determine the nominal interest rate.

6. The Demand for Money • Money is simply a part of your wealth. You can hold assets such as stocks or bonds, or you can hold wealth in the form of money. • Holding wealth in currency or checking deposits means that you sacrifice the potential income from interest and dividends earned on stocks and bonds. • So why hold money? Because it makes it easier to conduct transactions. Economists call this reason for holding money the transactions demand for money.

7. The Demand for Money • The opportunity cost of holding money is the return that you could have earned by holding your wealth in other assets. • The market rate of interest is a measure of the opportunity cost of holding money. PRINCIPLEof Opportunity CostThe opportunity cost of something is what you sacrifice to get it. • As interest rates increase, the opportunity cost of holding money increases, and the public will demand less money.

8. The Demand for Money 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 According to Keynes there were three motives for holding money: transactions, precautionary, and speculation. Of these the transactions motive is most important today.

9. Assumptions There are only two kinds of assets: bonds and money. Money earns zero interest, bonds earn positive nominal interest. Income and spending are not synchronized. Spending is exactly equal to income but occurs at times different from receiving the income. Nonsynchronization of income and spending describes the mismatch between the timing of money inflow to the household and the timing of money outflow for household expenses.

10. The Demand for Money The Transaction Motive  FIGURE 26.1 The Nonsynchronization of Income and Spending Income arrives only once a month, but spending takes place continuously.

11. Money Management and the Optimal Balance *There is a trade-off between the quantity of money people want to hold and the interest lost by holding money. *The optimal balance is the level of average money balance that earns the consumer the most net profit, taking into account both the interest earned on bonds and the costs paid for switching from bonds to money. *When interest rates are high people tend to hold very little money.

12. The Demand for Money The Transaction Motive  FIGURE 26.2 Jim’s Monthly Checking Account Balances: Strategy 1 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.

13. The Demand for Money The Transaction Motive  FIGURE 26.3 Jim’s Monthly Checking Account Balances: Strategy 2 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.

14. The Demand for Money The Transaction Motive  FIGURE 26.4 The Demand Curve for Money Balances 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.

15. 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. The precautionary demand for money has been largely replaced by credit cards.

16. The Total Demand for Money 1.The quantity of money demanded at any moment depends on the opportunity cost of holding money, the interest rate. 2.Total demand for money includes both household demand and business demand. 3.At any given moment there is a demand for cash and checkable deposit balances. Total money demand will always be less than income. The demand for money at any moment depends on the opportunity cost of holding money (the interest rate) and total income.

17. The Demand for Money ATMs and the Demandfor Money The Total Demand for Money Italy makes a great case study of theeffects of the spread of ATMs on thedemand for money. In Italy, virtuallyall checking accounts pay interest.What doesn’t pay interest is cash.In other words, in Italy there is an interest cost to carrying cash insteadof depositing the cash in a checking account.

18. The Demand for Money The Effects of Income and the Price Level on the Demand for Money  FIGURE 26.5 An Increase in Aggregate Output (Income) (Y) Will Shift the Money Demand Curve to the Right 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.

19. The Demand for Money The Effects of Income and the Price Level on the Demand for Money 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.

20. 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.

21. Supply and Demand in the Money Market 1.The Fed controls the money supply through its manipulation of the quantity of bank reserves. We assume it has a fixed target for the money supply. 2.Money demand is inversely related to the interest rate. If the money demand is greater than the money supply, the interest rate rises. If money demand is less than the money supply, the interest rate falls.

22. The Equilibrium Interest Rate Supply and Demand in the Money Market  FIGURE 26.6 Adjustments 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 r0 the price of bonds would be bid up (and thus the interest rate down), and at r1 the price of bonds would be bid down (and thus the interest rate up).

23. The Equilibrium Interest Rate An increase in the supply of money from to lowers the rate of interest from 7 percent to 4 percent. Changing the Money Supply to Affect the Interest Rate  FIGURE 26.7 The Effect of an Increase in the Supply of Money on the Interest Rate

24. The Equilibrium Interest Rate An increase in aggregate output (income) shifts the money demand curve from to , which raises the equilibrium interest rate from 4 percent to 7 percent. Increases in Y and Shifts in the Money Demand Curve  FIGURE 26.8 The Effect of an Increase in Income on the Interest Rate

25. Looking Ahead: The Federal Reserve and Monetary Policy tight monetary policy Fed policies that contract the money supply and thus raise interest rates in an effort to restrain the economy. easy monetary policy Fed policies that expand the money supply and thus lower interest rates in an effort to stimulate the economy.

26. Real and Nominal Interest Rates • Both nominal and expected real interest rates differ among developed countries.

27. Let’s summarize what we have learned so far in this chapter: • The interest rate is determined by the equality of the supply of money and the demand for money. • By changing the supply of money, the central bank can affect the interest rate. • The central bank changes the supply of money through open market operations, which are purchases or sales of bonds for money. • Open market operations in which the central bank increases the money supply by buying bonds lead to an increase in the price of bonds and a decrease in the interest rate. • Open market operations in which the central bank decreases the money supply by selling bonds lead to a decrease in the price of bonds and an increase in the interest rate.

29. A P P E N D I X A THE VARIOUS INTEREST RATES IN THE U.S. ECONOMY 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.
