The Financial Sector and the Economy
The financial sector is central to almost all macroeconomic
debates.
The real sector is the market for the production and
exchange of goods and services.
The financial sector is the market for the creation and
exchange of financial assets.
• Financial assets include money, stocks, and bonds.
• Plays a central role in organizing and coordinating our
economy.
© McGraw Hill 4
The Definition of Money
Money is a highly liquid financial asset that’s generally
accepted in exchange for other goods, is used as a reference
in valuing other goods, and can be stored as wealth.
Liquid means to be easily changeable into another asset or
good.
• Money is a financial asset that makes the real economy
function smoothly.
• Most of what is considered money today is not currency
but exists in the form of electronic holdings.
© McGraw Hill 5
The Functions of Money
1. Medium of exchange
• It does not have to have any inherent value to serve this
function.
• It makes it possible to trade real goods and services
without bartering.
2. Unit of account
• It serves as a measure of value.
• It is useful in this function as long as its value relative to
other prices does not change too quickly.
3. Store of wealth
© McGraw Hill 6
The U.S. Central Bank: The Fed
The Federal Reserve Bank (the Fed) is the U.S. central
bank, whose liabilities serve as cash in the United States.
• Federal Reserve notes are liabilities of the Fed that serve
as cash in the United States.
A bank is a financial institution whose primary function is
accepting deposits for, and lending money to, individuals and
firms.
Individuals’ deposits in savings and checking accounts serve
the same purpose as does currency and are also considered
money.
© McGraw Hill 7
Alternative Measures of Money
Economists have developed different measures of money.
Two are M1 and M2.
• M1 consists of currency in the hands of the public plus
checking accounts.
• M2 is made up of M1 plus savings and money market
accounts, small-denomination time deposits (CDs), and
retail money funds.
© McGraw Hill 8
Components of M1 and M2
© McGraw Hill 9
Distinguishing Between Money and Credit
Credit cards are not money.
Credit card balances are assets of a bank in the form of a
prearranged loan and liabilities of the credit card user.
Generally credit card holders carry less cash.
A debit card serves the same function as a checkbook-allows
you to spend money in your bank account.
© McGraw Hill 10
The Creation of Money: Step One
The Fed creates money by simply printing currency.
• Currency is a financial asset to the bearer and a liability to
the Fed.
The bearer deposits the currency in a checking account at
the bank.
• The form of money has changed from currency to a bank
deposit.
© McGraw Hill 11
The Creation of Money: Step Two
The bank lends a fraction of the deposit.
The amount of money has expanded:
Initial deposit + new loan
The amount of money is multiplied.
© McGraw Hill 12
The Process of Money Creation
Reserves are currency and deposits a bank keeps on hand
or at the Fed or central bank, to manage the normal cash
inflows and outflows.
The reserve ratio is the ratio of reserves to deposits a bank
keeps as a reserve against cash withdrawals.
Banks can keep more reserves: excess reserve ratio.
Reserve ratio = required reserve ratio + excess reserve ratio
© McGraw Hill 13
Determining How Many Demand Deposits Will
Be Created
To find the total amount of deposits that will be created,
multiply the original deposit by 1/r, where r is the reserve
ratio.
If the original deposit is $100 and the reserve ratio is 10
percent (0.1), the amount of money ultimately created is:
1/r = 1/0.1 = 10
$100 × 10 = 1,000
New money created = $1000 − $100 = $900.
© McGraw Hill 14
Calculating the Money Multiplier
We will call the ratio 1/r the money multiplier.
• The money multiplier is the measure of the amount of
money ultimately created per dollar deposited in the
banking system, when people hold no currency.
It tells us how much money will ultimately be created by the
banking system from an initial inflow of money.
The higher the reserve ratio, the smaller the money
multiplier, and the less money will be created.
© McGraw Hill 15
An Example of the Creation of Money
Round Bank Gets Bank Keeps (r = 20%) Bank Loans (80%)
1 $10,000 $2,000 $8,000
2 $8,000 $1,600 $6,400
3 $6,400 $1,280 $5,120
4 $5,120 $1,024 $4,069
… … … …
Infinite $50,000 = $10,000 + $40,000
© McGraw Hill 16
Why is the Financial Sector Important to Macro?
For every real transaction, there is a financial transaction that
mirrors it.
The financial sector channels savings back into spending.
For every financial asset, there is a corresponding financial
liability.
• Financial assets are assets such as stocks or bonds,
whose benefit to the owner depends on the issuer of the
asset meeting certain obligations.
• Financial liabilities are obligations by the issuer of the
financial asset.
© McGraw Hill 17
The Financial Sector as a Conduit for Savings1
Financial institutions channel savings back into the spending
stream as loans.
Saving is outflows from the spending stream from government,
households, and corporations.
• Savings deposits, bonds, stocks, life insurance.
Loans are made to government, households, and corporations.
• Business loans, venture capital loans, construction loans,
investment loans.
© McGraw Hill 18

The Role of Interest Rates in the Financial Sector
The interest rate is the price paid for use of a financial asset.
The long-term interest rate is the price paid for financial
assets with long maturities.
• The market for long-term financial assets is called the
loanable funds market.
The short-term interest rate is the price paid for financial
assets with short maturities.
• Short-term financial assets are called money.
© McGraw Hill 20
Why People Hold Money
The only reason people would be willing to hold money is if
they get some benefit from doing so.
• The transactions motive is the need to hold money for
spending.
• The precautionary motive is holding money for
unexpected expenses and impulse buying.
• The speculative motive is holding cash to avoid holding
financial assets whose prices are falling.
© McGraw Hill 21
The Many Interest Rates in the Economy1
The economy doesn’t have just a single interest rate; it has
many.
Each financial asset will have an implicit interest rate
associated with it.
In a multiple-asset market, the potential for the interest rate
in the loanable funds market to differ from the interest rate in
the market for a particular asset is large.
• The result can be a financial asset market bubble.
© McGraw Hill 22
The Many Interest Rates in the Economy2
An example of a financial asset market bubble:
• In the early 2000s prices of houses increased by 10% to
15% per year.
• Many people bought houses for speculative purposes.
• In 2006, people lowered their expectations of housing
price appreciation.
• The demand for housing decreased substantially, and the
equilibrium price fell.
© McGraw Hill 23
Chapter Summary1
• Money is a highly liquid financial asset that serves as a
unit of account, a medium of exchange, and a store of
wealth.
• There are various measures of money; the two most
important are M1 and M2.
• Banks create money by loaning out deposits.
• The money multiplier is 1/r. It tells you the amount of
money ultimately created per dollar deposited in the
banking system.
• The financial sector is the market where financial assets
are created and exchanged.
© McGraw Hill 24
Chapter Summary2
• Interest rates play a crucial role in channeling savings
back into the economy as investment.
• People hold money for three reasons: (1) the transactions
motive, (2) the precautionary motive, and (3) the
speculative motive. The demand for money is inversely
related to the interest rate paid on money.
• Dramatically higher interest rates paid on particular assets
compared to other financial assets can cause bubbles,
which can cause problems for an economy.
