FINANCES IN A MARKET ECONOMY
In the markets for goods, services, and labor,
prices are expressed in terms of some currency,
or money. But money itself is also traded in
market economies, because some people want
to save money to use in the future, while other
people -- including many businesses -- want
to borrow money to use today. The price for
the use of that money -- known as an interest
rate -- is determined in the markets where
these funds are exchanged.
From a broader perspective, banks and other
firms in a market economy's financial sector
are most important in linking those who have
resources to save and invest with those who
have the most promising uses for those funds,
and are therefore willing to pay for their
use. Through these markets, decisions about
how and where to invest funds are decentralized,
just as production and consumption decisions
are decentralized in the markets for goods
and services.
To Buy a House
Let's look at our family of Robert and Maria
several years after their talk about job
changes and further education. Maria did,
in fact, take an administrative job with
the school system, and Robert pursued advanced
training in computer programming and found
employment in a new and growing field. As
a result, Robert and Maria, having earned
higher incomes than previously, have been
able to save money toward what is normally
the largest single purchase that most individuals
ever make: a house.
Here, the role of financial institutions such
as banks is critical. Banks serve two related
functions. On one hand, they accept deposits
from people like Maria and Robert -- savers
who want to keep their money safe and to earn
interest on it. On the other, they lend money
to borrowers who can demonstrate that they
have the financial ability to pay back such
a loan over time. Borrowers and lenders are
not only individuals, of course, but also private
companies that wish to save their money or
that wish to borrow money and invest in new
or expanded businesses.
In a market economy, individuals like Maria
and Robert can play the role of savers and
borrowers at different times. To attract their
money, banks offer savers like Maria and Robert
a certain rate of interest in competition with
other banks and savings institutions. Now,
Robert and Maria have approached the bank as
potential borrowers, seeking a loan that will
enable them to buy a house. If the bank finds
that they have the income to pay back the loan
in monthly installments over a period of years,
the bank may loan them the money. It will,
however, charge them a higher rate of interest
as borrowers than it paid them previously as
savers: the difference is the bank's rate of
return for the financial services it provides.
Borrowing and Investing
The same process takes place with businesses
seeking investment funds for new factories,
stores, and equipment. And as with other
industries in a market economy, competition
among banks helps ensure that interest rates
will be as low as possible while still providing
a satisfactory rate of return to banks that
are run well and efficiently. Further, because
the pool of money available for loans is
limited, the borrowers -- individuals and
companies -- will compete among themselves
to win the bank's approval. This competition
helps ensure that bank loans are allocated
to investments with the highest potential
return in a manner much more efficient than
if the government made borrowing and loan
decisions itself.
Businesses seek these investment loans for
new facilities or machinery to increase their
production and sales. These firms expect to
earn profits on these new investments for many
years, so they are willing to pay interest
for funds they can use to purchase those assets
and start their production now, not later.
Of course, if the interest they have to pay
is higher than the rate of return they expect
to earn, the businesses won't borrow the funds.
And in fact, if a company doesn't have an investment
in mind that pays more than the current interest
rate on borrowed funds, it will save the money
rather than trying to borrow more funds itself.
Or, more likely, the company will try to shift
its resources into a different line of business,
where the expected rate of return is higher
than the rate paid on borrowed funds. That
is simply another way in which resources are
directed to firms that have identified the
most profitable uses of resources -- based,
as we have seen earlier, on providing the things
consumers want most, at prices that meet or
beat the prices for similar products offered
by competing firms.
Here, too, international trade can be important.
Just as countries can exchange products, they
can also exchange financial services and investment
funds. Foreign investment can increase the
amount of money, or capital, available for
businesses seeking to borrow and invest. By
competing with domestic banks and financial
institutions, foreign investment can also help
keep interest rates -- the cost of money --
down.
Foreign investment, if perceived to be too
extensive, can trigger fears that parts of
the economy are no longer under a nation's
control. Such fears are almost always unwarranted,
in large part because the dynamics of a market
economy apply equally to international as well
as national investments and business activity.
Foreign direct investment, like any other kind
of investment, is a vote of confidence in economic
growth. By bringing in a new source of funds,
foreign investment usually improves efficiency,
adds management expertise, and helps keep interest
rates down.
Stock Markets and Investments
As we have seen in the example of Robert and
Maria, successful banks earn money by serving
as an intermediary for savers and borrowers,
and play an important role in the economic
system by bringing them together so that
funds that are saved can be reinvested.
There are other, even more specialized kinds
of businesses in the financial sector of a
large market economy. Suppose that, in a few
years, Robert and Maria decide to start a small
business that takes advantage of their combined
skills and experience in education and computer
programming. Together, they develop a line
of educational computer software for schools,
and they need money to start the new business,
called R&M Educational Software. They could
go back to the banks and try to secure a loan,
as they did for their house. Or they could
sell ownership shares, known as corporate stocks,
in their fledgling business to hundreds, even
thousands of people who believe that R&M
Software has the potential to make a profit.
Small entrepreneurs such as Maria and Robert,
as well as the world's largest corporations,
offer such stocks for sale through brokers
who work on stock exchanges throughout the
world.
The people who buy these stocks are willing
to invest some of their own money in these
businesses in return for a share of the businesses'
future profits. These people become, legally,
the real owners of the firms and receive voting
rights for every share of stock they purchase.
That gives them a voice in what the company
does, and in deciding who the directors and
executives of the company will be.
They also share in the risks of the company.
If R&M Educational Software performs poorly,
or fails altogether, the investors will lose
some or all of their investment money. If the
company succeeds, however, these same investors
will have an opportunity to realize a profit
on their investment, whether they choose to
hold their shares for even longer-term gain
or sell their shares for many times their initial
value.
As long as stockholders expect a company to
do well, they will hold that stock to claim
a share of the firm's expected profits, and
may even buy more shares. But stockholders
who aren't happy with the company's future
outlook for sales and profits will sell the
stock they own on a stock market, through companies
that specialize in finding both buyers and
sellers of stocks of all of the major corporations
in the economy. These companies are known as
brokerage houses, and it is groups of these
firms that have joined together to establish
the major stock markets in locations around
the world such as New York, Tokyo, and London.
Like the banking industry, these stock markets
have come to play an important role in their
national economies and in international trade.
They help stockholders and other people make
investment decisions, evaluate how efficiently
corporations are being run, and assess the
general business climate. This is done through
the prices of the thousands of corporate stocks
that are traded daily on these exchanges, rising
and falling in response to changing business
conditions for individual firms, their competitors,
and the overall economy.
The investment process offers individual savers
and investors a great deal of freedom and opportunity
in deciding what risks and new ventures to
undertake. They stand to gain substantially
if they save and invest wisely; but they can
also lose a great deal if their investments
are not sound. That is why most investors choose
not to put all of their investments in one
project or company, but instead keep some of
their assets in very safe, "tried and
true" companies or accounts. Only those
who choose to take a big gamble and put all
of their assets in a small number of high-risk
ventures are likely to lose a fortune in the
financial markets or, on the other hand, to
make one.
Over the past century, it is revealing to
compare the record of private investments in
the development of new products and technologies
to the investment record of national governments,
especially those with centrally planned economies.
The record of the private-sector investments,
despite periods of failure, is clearly superior.
Why? The reasons again point to the very nature
of market economies: a decentralized process
in which large numbers of people are making
investment and borrowing decisions in response
to changing economic conditions, not a small
group in a central government. Further, the
decisions are made by those whose own money
is at stake -- certainly a strong motivation
for making careful, shrewd choices.
