MONETARY
POLICY*
The major assets on the Fed’s balance sheet are gold
and foreign exchange, U.S. government securities, and
loans to banks. The major liabilities are Federal Reserve
notes in circulation (currency) and banks’ deposits (reserves). The monetary base is the sum of Federal Reserve notes, coins, and banks’ deposits at the Fed.
Key Concepts
„ The Federal Reserve System
The Federal Reserve System (or the Fed) is the central
bank for the United States. A central bank is a bank
for banks and a public authority that regulates financial
firms. The Fed is responsible for monetary policy, so
it adjusts the quantity of money in circulation.
Three key players in the Fed are:
♦ The Board of Governors — seven members appointed by the President and confirmed by the
Senate for 14-year terms. This group oversees operations of the Fed.
♦ The Federal Reserve Banks —12 regional banks,
each of which has a president.
♦ The Federal Open Market Committee (FOMC
FOMC)
FOMC
— the Fed’s main policy-making group. Voting
members are the Board of Governors, the president
of the Federal Reserve Bank of New York and, on a
rotating basis, presidents of four other regional
Federal Reserve banks.
The Fed has three policy tools:
♦ Required reserve ratio — the Fed sets the required
reserve ratio, the minimum percentage that depository institutions must hold as reserves.
♦ Discount rate — the interest rate at which the Fed
stands ready to lend reserves to commercial banks.
♦ Open market operation — the purchase or sale of
government securities—U.S. Treasury bills and
bonds—by the Fed.
„ Controlling the Quantity of Money
To increase the quantity of money, the Fed’s three policy tools are used as follows:
♦ Changes in the required reserve ratio: A decrease in
the required reserve ratio increases banks’ lending
and so increases the quantity of money.
♦ Changes in the discount rate: A decrease in the discount rate raises banks’ borrowing from the Fed,
thereby increasing their reserves and so increases
the quantity of money.
♦ Open market operations: When the Fed buys government securities, banks’ reserves increase. (These
reserves rise whether the Fed buys securities from a
bank or from a member of the public.) The rise in
banks’ reserves leads them to increase their lending
and so increases the quantity of money.
To decrease the quantity of money, the Fed reverses
these policy actions, increasing the required reserve
ratio, raising the discount rate, or selling government
securities.
The money multiplier is the amount by which a
change in the monetary base is multiplied to determine
the change in the quantity of money. The money multiplier is greater than 1.0. The larger the currency
drain, the smaller the money multiplier.

Interest rate (percent per year)
Four factors influence the demand for money:
♦ The price level — An increase in the price level increases the nominal demand for money.
♦ The interest rate — An increase in the interest rate
raises the opportunity cost of holding money and
decreases the quantity of real money demanded.
♦ Real GDP — An increase in real GDP increases the
demand for money.
♦ Financial innovation — Innovations that lower the
cost of switching between money and other assets
decrease the demand for money.

equilibrium interest rate is 5 percent.
♦ If the Fed increases the quantity of money, the
supply of money curve shifts rightward and the
equilibrium interest rate falls.
♦ If the Fed decreases the quantity of money, the
supply of money curve shifts leftward and the equilibrium interest rate rises.

Figure 13.1 shows the demand for money curve (MD).
The real quantity of money equals the nominal quantity divided by the price level. Changes in the interest
rate create movements along the demand curve;
changes in the other relevant factors change the demand and shift the demand curve.
„ Interest Rate Determination
An interest rate is the percentage yield on a financial
security; other variables being the same, the higher the
price of the security, the lower is the interest rate.
The interest rate is determined by the equilibrium in
the market for money, as illustrated in Figure 13.2. The
real supply of money is $3.0 trillion, so the supply
curve of money is MS. (The Fed sets the quantity of
„ Monetary Policy, Real GDP, and the Price
Level
The Fed’s actions ripple through the economy. Higher
interest rates:
♦ Decrease investment and consumption expenditure
♦ Increase the foreign exchange rate, which then
decreases net exports
♦ A multiplier process then occurs
If the Fed tightens to fight inflation, the quantity of
money decreases, which raises the interest rate and
thereby decreases investment. The decrease in investment leads to a multiplier effect that decreases aggregate
demand, thereby lowering the price level and decreasing real GDP. If the Fed eases to fight a recession, the
reverse results occur.
The Fed in Action
The data show that short-term interest rates generally
move together. The data also show that interest rates
MONETARY POLICY
generally fall when the quantity of money increases and
generally rise when the quantity of money decreases.
Paul Volcker: In 1979, when Volcker became chairman
of the Fed, the inflation rate was high. The Fed slowed
the growth rate of the quantity of money, interest rates
rose, the inflation rate fell, and the economy went into
a recession.
Alan Greenspan: Greenspan took over as chairman in
1987. From 1988 to 1990, the Fed slowed the monetary growth rate and forced interest rates higher. In
1990 a recession occurred; after that the Fed nudged
along the expansion that started in 1992 until it ended
in 2001. In 2001 the Fed cut the interest rate on eleven
occasions because of concern about the recession.

2. DOES AN OPEN MARKET OPERATION INCREASE
OR DECREASE THE QUANTITY OF MONEY ? Trying
to keep track of whether an open market purchase
of government securities by the Fed increases or decreases the quantity of money can be confusing.
One way to remember their effects is to think of
the following: “When the Fed buys government securities, it sells money; when the Fed sells government securities, it buys money.” By associating the
purchase of securities with the sale of money and
vice versa, keeping track of whether a purchase or
sale of government securities increases the quantity
of money becomes straightforward.
Questions
Helpful Hints
„ True/False and Explain
1. OPEN MARKET OPERATIONS : This activity is by
far the Fed’s most important policy tool. Open
market operations occur every business day. The
term “open market operation” refers to the Fed’s
purchase or sale of government securities. There is
nothing mysterious about this process: All the Fed
does is buy or sell government securities.
However, even aside from the differences in scale,
the economic impact of your purchase of a government security is different from that of the Fed’s
purchase. In particular, when you pay for your purchase, you use money that already exists in the
economy. The total amount of money in the economy does not change. But when the Fed pays for a
purchase of $5,000 of securities, the Fed introduces
new money into the economy. If the Fed buys
$5,000 of securities from a broker, it gives the broker a check drawn on the Fed. The broker presents
the check to his or her bank. The bank increases
the broker’s account for $5,000 and then presents
the check to the Fed. In turn, the Fed increases the
bank’s checking account at the Fed for $5,000. Because funds kept in the bank’s checking account at
the Fed are reserves for the bank, the bank gains reserves. You know that when banks gain reserves,
they loan the excess reserves and the quantity of
money expands by a multiple of the initial increase
in reserves. So the Fed’s purchase of $5,000 of government securities will have a multiplier effect on
the quantity of money.

„ Answers to Short Answer Problems
1. a. An increase in the required reserve ratio means
that for every dollar of deposits banks must keep
more reserves either in their vault or at the Federal Reserve. As a result, banks’ excess reserves
— the reserves over and above the required reserves — fall because the total amount of required reserves increases. Because banks need to
keep more reserves on hand for each dollar of
deposits, they can make fewer loans. Then, with
fewer loans, the quantity of money decreases.
b. An increase in the discount rate makes borrowing reserves from the Fed more expensive for
banks. They respond by reducing the amount of
reserves they borrow. As a result, their excess reserves decline. Then, similar to the answer in
part (a), the decrease in banks’ excess reserves
leads to a decrease in the quantity of money.
2. An open market purchase of government securities
by the Fed increases reserves by increasing one of its
components, banks’ deposits with the Federal Reserve. The process is direct: the Fed pays for the securities by increasing the bank’s deposit at the
Federal Reserve, which directly increases banks’ reserves. Reserves expand by the amount of the open
market purchase. (If the purchase is from the nonbank public, the Fed pays by writing checks on itself, which the sellers of the securities deposit in
their banks. The banks increase the sellers’ deposits
at the bank, and, in turn, present the checks to the
Federal Reserve. The Fed then increases the banks’
deposits at the Fed.)

3. Table 13.6 shows the effect of the Fed’s purchase of
$10 billion of government securities. Compared to
the initial amounts shown in Table 13.1, government securities owned by the Fed have increased by
$10 billion (from $380 to $390 billion) and the
amount of banks’ deposits at the Fed also has increased by $10 billion (from $40 to $50 billion).
The monetary base equals the sum of Federal Reserve notes plus banks’ deposits. Hence the monetary base has increased by $10 billion, from $420
billion initially to $430 billion after the purchase of
government securities. If the money multiplier is
2.8, the quantity of money will increase by 2.8
times the change in the monetary base, or (2.8)($10
billion) = $28 billion.

lion, to $30 billion. The monetary base, which
equals the sum of Federal Reserve notes plus banks’
deposits, falls from $420 to $410 billion, a decrease
of $10 billion.
Finally, the change in the quantity of money equals
the money multiplier, 2.8, times the change in the
monetary base, –$10 billion, or (2.8)(–$10 billion)
= –$28 billion; that is, the quantity of money declines by $28 billion.

4. Table 13.7 shows the effect of the sale of $10 billion
of government securities. The amount of government securities decreases by $10 billion, to $370
billion. As the bank pays for this purchase, the
amount of its deposit — and hence the total
amount of banks’ deposits — decreases by $10 bil-

5. The effect of the banks’ withdrawal of $10 billion
from their deposits is presented in Table 13.8. The
only effects are on the liability side of the balance
sheet. The amount of Federal Reserve notes increases by $10 billion to $390 billion, and the
amount of banks’ deposits decreases by $10 billion
to $30 billion. The monetary base equals the sum of
Federal Reserve notes and banks’ deposits. The key
result in this question is that the effect on the
monetary base is nil because the two changes offset
each other. So neither the monetary base nor the
quantity of money change.
6. Banks’ withdrawals of currency from their deposits
at the Fed has no effect on the quantity of money.
(Similarly, their deposit of Federal Reserve notes in
their deposits at the Fed have no effect on the
quantity of money.)
In general, setting aside when banks borrow reserves
from the Fed (which is a relatively tiny amount of
reserves), the quantity of money changes in reaction
to the Federal Reserve’s actions. Because the quantity of money changes whenever the Fed buys or
sells government securities, the Fed can use the purchase or sale of government securities — which are
open market operations — to control the nation’s
quantity of money.

CHAPTER 13 (28)
the money multiplier is 2.5, the monetary base
must expand by $80 billion. (An additional $80
billion in the monetary base supply will lead to a
(2.5)($80 billion) = $200 billion increase in the
quantity of money.) In order to increase the
monetary base by $80 billion, the Fed must purchase $80 billion of government securities.

7. a. Figure 13.4 shows the $100 billion increase in
the quantity of money as the rightward shift
from MS 0 to MS1.
b. The initial interest rate was 6 percent; after the
increase in the quantity of money, the equilibrium interest rate fell, to 4 percent.
c. An increase in the quantity of money means
that, at the initial interest rate (6 percent), the
quantity of money supplied is greater than the
quantity of money demanded. Money holders
want to reduce their money holdings and do so
by buying financial assets. The increase in the
demand for financial assets raises the price of financial assets and thus lowers their interest rate.
As interest rates fall, the quantity of money demanded increases, which reduces the excess supply of money. This process continues until the
interest rate has fallen sufficiently so that the
quantity of money demanded is the same as the
quantity of money supplied. The interest rate
that sets the new quantity of money supplied
equal to the quantity of money demanded is the
(new) equilibrium interest rate.
8. a. When the interest rate is 6 percent, the quantity
of money demanded is $300 billion. Hence the
quantity supplied also must be $300 billion.
b. In order to reduce the interest rate to 4 percent,
the Fed must increase the quantity of money
supplied to $500 billion. So the quantity of
money must increase by $200 billion. Because
1. “Well, you’re close but not quite right. Look, the
deal is that you have to be careful to distinguish
between the Fed and other branches of the government. So when the federal government runs a deficit, it’s not the Fed that sells the government
securities necessary to cover the deficit but the U.S.
Treasury. And the Treasury sells the securities to
anyone who will buy them, that is, to you, me, an
insurance company, or whomever.
“Since it was founded in 1913, the Federal Reserve
has bought more than $450 billion of U.S. government securities. So, the Fed has a lot that it can sell
if it wants. But, if you and I have bought some government securities in the past, we could sell them
just like the Fed could sell the securities it holds. Of
course, we probably can’t sell as much as the Fed
can....
“However, the amount isn’t the key thing; it is that
the Fed’s securities are like ours in that they aren’t
newly issued securities. That is, unlike the Treasury
selling new securities to finance the deficit, when the
Fed sells its securities and when we sell ours, we
aren’t helping finance a new deficit. So when the
federal government runs a deficit, it’s the U.S.
Treasury that sells securities to finance the deficit,
not the Fed and not us!”
2. “This is another great set of questions. Here are a
couple of great answers! Sure, the Fed makes a lot of
‘profit’ and for exactly the reasons you stated: It
earns a lot of interest income on its government securities and it pays no interest expense. But the Fed
doesn’t do anything wild and crazy with its profit:
There’s not a party to die for. Instead, the Fed pays
its costs with its revenue. However, the amount of
revenue easily covers those costs, so what happens to
the extra? The Fed gives it back to the Treasury.
That’s right, the Fed sends the extra profit back to
the U.S. Treasury so the Treasury can use it as revenue to help pay for the government’s expenditures.”
