Many naïve observers of the market economy dismiss
concern with the "bottom line" as a purely arbitrary social
convention. To these critics, it seems senseless that a factory producing, say,
medicine or shoes for toddlers stops at the point when the owner decides that
profit has been maximized. It would certainly be physically possible to
produce more bottles of aspirin or more shoes in size 3T, yet the boss doesn't
allow it, because to do so would "lose money." On the other hand,
many apparently superfluous gadgets and unnecessary luxury items are produced
every day in a market economy, because they are profitable. Observers who are
outraged by this system may adopt the slogan: "Production for people, not
profit!"
Such critics do not appreciate the indispensable
service that the profit-and-loss test provides to members of a market economy.
Whatever the social system in place, the regrettable fact is that the material
world is one of scarcity — there are not
enough resources to produce all the goods and services that people desire.
Because of scarcity, every economic decision involves trade-offs. When scarce resources are devoted to
producing more bottles of aspirin, for example, there are necessarily fewer
resources available to produce everything else. It's not enough to ask,
"Would the world be a better place if there were more medicine?" The
relevant question is, "Would the world be a better place if there were
more medicine and less of the other goods and services that
would have to be sacrificed to produce more medicine?"
In standard introductory textbooks, they often define
the economic problem as society's decision on how to
allocate scarce resources into the production of particular goods and services.
In reality, "society" doesn't decide anything; individual members of
society make decisions that interact to determine the ultimate fate of all the
resources at humanity's disposal. In the pure market economy, everyone in
society obeys the rules of private property, which assign ownership claims to
particular units of resources.
In this context, market prices are formed when
individuals engage in voluntary exchanges with each other. The resulting prices
in turn give entrepreneurs the ability to calculate (expected) profits and
losses from various possible activities. It is the interaction of property
owners in voluntary trades that "determines" what goods and services
get produced, but the signals provided by market prices — and the resulting
calculations of profit and loss — help the property owners make informed decisions.
It might be useful to step back and look at the big
picture. The entrepreneurs offer money to the owners of labor services, capital
goods, and natural resources. The entrepreneurs then use these inputs to
produce goods and services which they sell to consumers for money (see figure
below).
When a particular entrepreneurial venture goes
"out of business," what that ultimately means is that consumers were
not willing to spend enough money on its finished output to cover the offers
the entrepreneur needed to make in order to bid the scarce inputs away from otherentrepreneurs who wanted the inputs for their enterprises.
To see this principle more concretely, let's work with
a silly example. Suppose a successful builder dies and passes on his business
to his foolish son. The son gets the bright idea to build new apartment
buildings covered with pure gold. He correctly estimates that there would be
high demand for apartments where the elevator, hallways, and kitchen shelves
were coated with gold. In fact, the son can rent his units for much higher
monthly fees than the owners of normal apartments in similar locations.
Of course, this isn't the whole story. Even though his
revenues are very high, the foolish son's production costs are astronomical. In
addition to the labor, wood, concrete, and other items, he must spend hundreds
of millions of dollars buying large quantities of gold. His accountants inform
him that despite the higher revenues, he is losing incredible amounts of money
because of his decision to coat the apartments with gold. The son will have to
either wisen up quickly, or he will squander all of his wealth. Either way, he
won't be building apartments coated with gold for very long.
Now if we were to interview the son and ask him what
happened, he might say, "It's too expensive to use gold in my
business." But notice that this can't be true for all entrepreneurs. After all, the reason gold is so expensive is that other buyers are paying such high prices for it. For
example, jewelers still find it profitable to buy gold in order to make necklaces
and earrings, and dentists still find it profitable to use gold for fillings.
No jeweler would say, "It's too expensive to use
gold in my business."
Loosely speaking, the profit-and-loss system
communicates the desires of consumers to the resource owners and entrepreneurs
when they are deciding how many resources to send into each potential line of
production. It's ultimately not the owners of gold mines nor the captains of
industry who determine how gold will be used in a market economy. Instead,
these decisions are largely guided by the spending decisions of the consumers. It is the consumers' demands for normal
versus gold-coated apartments, in conjunction with their demands for silver-
versus gold-coated necklaces, that leads to the outcome that gold-coated
apartments are ridiculously unprofitable while gold-coated necklaces are
perfectly sensible.
The profit-and-loss test provides structure to the
free-enterprise system. People are free to start new businesses and to sell
their resources (including the labor services of their bodies) to whomever they
wish. In a market based on the institution of private property, profits occur
when an entrepreneur takes resources of a certain market value and transforms
them into finished goods (or services) of a higher market
value. This is the important sense in which profitable entrepreneurs are
providing a definite service to others in the economy. Without the feedback of
profit-and-loss calculations, entrepreneurs would have no idea if they were
making economical use of the resources used up by their
business operations.
