Monetary Policy and Interest
• Monetary policy is the behavior of the
Federal Reserve concerning the money
supply.
• Interest is the fee that borrowers pay to
lenders for the use of their funds.
• Interest rate is the annual interest
payment on a loan expressed as a
percentage of the loan.

The Demand for Money
• The main concern in the study of the
demand for money is:
• 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 interestbearing securities, such as bonds.

The Total Demand for Money
• The quantity of money demanded at
any moment depends on the
opportunity cost of holding money, a
cost determined by the interest rate.
• A higher interest rate raises the
opportunity cost of holding money and
thus reduces the quantity of money
demanded.

Transactions Volume
and the Price Level
• The total demand for money in the
economy depends on the total dollar
volume of transactions made.
• The total dollar volume of
transactions, in turn, depends on the
total number of transactions, and the
average transaction amount.

• When output
(income) rises, the
total number of
transactions rises,
and the demand for
money curve shifts
to the right.

Transactions Volume
and the Price Level
• When the price level rises, the
average dollar amount of each
transaction rises; thus, the quantity
of money needed to engage in
transactions rises, and the demand
for money curve shifts to the right.

The Determinants of
Money Demand: Review
Determinants of Money Demand
1. The interest rate: r (negative effect)
2. The dollar volume of transactions (positive effect)
a. Aggregate output (income): Y (positive effect)
b. The price level: P (positive effect)
• Money demand is a stock variable,
measured at a given point in time.

The Determinants of
Money Demand: Review
• Money demand answers the
question:
• How much money do firms and
households desire to hold at a specific
point in time, given the current interest
rate, volume of economic activity, and
price level?

The Equilibrium Interest Rate

• The point at which
the quantity of
money demanded
equals the quantity
of money supplied
determines the
equilibrium interest
rate in the economy.

• At r1, the amount of
money in circulation is
higher than
households and firms
wish to hold. They
will attempt to reduce
their money holdings
by buying bonds.

• At r2, households
don’t have enough
money to facilitate
ordinary transactions.
They will shift assets
out of bonds and into
their checking
accounts.

lowers the rate of
interest.

Increases in Y and Shifts
in the Money Demand Curve
© 2004 Prentice Hall Business Publishing
• An increase in
aggregate output
(income) shifts the
money demand curve,
which raises the
equilibrium interest rate.
• An increase in the price
level has the same
effect.

• Tight monetary policy refers to Fed
policies that contract the money
supply in an effort to restrain the
