Meaning of Money
• Money (or the “money supply”): anything
that is generally accepted as payment for
goods or services or in the repayment of
debts.
• To define money merely as currency is
much too narrow a definition for
economists ,Because
• checks are also accepted as payment for
purchases, checking account- deposits

MEANING OF MONEY
• savings deposits, can, in effect, function as
money if they can be quickly and easily
converted into currency or checking account
deposits.
• As you can see, no single definition of
money or the money supply is possible, even
for economists.

B- Unit of Account: that is, money is used to
measure value in an economy. We measure
the value of goods and services in terms
of money, just as we measure weight in

Functions of Money
• C- Store of Value: This function of money is
useful because most of us do not want to spend
our income immediately upon receiving it, but
rather prefer to wait until we have the time or the
desire to shop.
• Money is not only a store of value; any asset—
whether money, stocks, bonds, land, houses, art,
can be used to store value .
• But money is more liquid compere with other
asset

Functions of Money
oMoney also functions as a store of
value
– Used to save purchasing power over time
– Other assets also serve this function.
– Money is the most liquid of all assets but loses
value during inflation.

Money loses value during
hyperinflation.
For Example:
• Hyperinflation occurred in Germany after World
War I, with inflation rates sometimes more 1,000%
per month.
• By the end of the hyperinflation of 1923, the price
level had risen to more than 30 billion times what it
had been just two years before

3- Evolution of the Payments System
• The payments system has been evolving over
centuries, and with it the form of money. At one
point, precious metals such as gold were used as
the principal means of payment and were the main
form of money.
• Later, paper assets such as checks and currency
began to be used in the payments system as
money
• Where the payments system is heading has an
important bearing on how money will be defined in
the future.

Evolution of the Payments System
types of payment:
• Commodity Money: valuable, easily
standardized and divisible commodities (e.g.
precious metals, cigarettes)
• Fiat Money: the next development in the
payment system was paper money decreed
by governments as legal tender
• Major drawbacks of paper currency and
coins are that they are easily stolen and can
be expensive to transport in large amounts
1-14

Evolution of the Payments System
• Checks: an instruction to your bank to
transfer money from your account
• Not need to carry large amounts of currency
• reduces the transportation costs
• that they can be written for any amount up
to the balance in the account .

Evolution of the Payments System
• Electronic Payment : The development of
inexpensive computers and the spread of the
Internet now make it cheap to pay bills
electronically.
• Not only do you save the cost of the stamp, but
paying bills becomes (almost) a pleasure
requiring little effort.
• . E-pay is becoming more and more common in
the US.

Evolution of the Payments System

• Debit card , which look like credit cards, enable
consumers to purchase goods and services by
electronically transferring funds directly from their
bank accounts to a merchant’s account.

Evolution of the Payments System
– Stored-value card(smart card)
• In Asian countries, such as Japan and Korea , cell
phones now have a smart card that raises the
expression “pay by phone” to a new level.
• Smart cards can be loaded from ATM machines,
personal computers with a smart card reader, or
specially equipped telephones.
– E-cash : A consumer gets e-cash by setting up an
account with a bank that has links to the Internet and
then transferring the e-cash to her PC. ( pay pal )

4- Are We Headed for a Cashless
Society?
• Predictions of a cashless society have been
around for decades, but they have not come
to fruition.
• Although e-money might be more
convenient and efficient than a payments
system based on paper, several factors
work against the disappearance of the paper
system.
• However, the use of e-money will likely still
increase in the future.

5-Will Bitcoin Become the Money of
the Future?
• Bitcoin is type of electronic money created
in 2009.
• By “mining,” Bitcoin is created by
decentralized users when they use their
computing power to verify and process
transactions.
• Although Bitcoin functions as a medium of
exchange it is unlikely to become the money
of the future because it performs less well
as a unit of account and a store of value.

6- Measuring Money
• How do we measure money? Which
particular assets can be called “money”?
• Construct monetary aggregates using the
concept of liquidity:
– M1 (most liquid assets) = currency + traveler’s
checks + demand deposits + other checkable
deposits
1-21

Measuring Money
• M2 (adds to M1 other assets that are not so
liquid)
M2 = M1 + small denomination time deposits
+ savings deposits and money market
deposit accounts + money market mutual
fund shares

The Federal Reserve’s Monetary
Aggregates
• M1 versus M2: Does it matter which
measure of money is considered?
• M1 and M2 can move in different directions
in the short run (see figure).
• Conclusion: the choice of monetary
aggregate is important for policymakers.
