The quip “If you think it’s expensive now, just wait
until it is free” is funny because of the unfortunate truth it contains. The
truth is unfortunate less because it’s impossible to provide benefits without
costs than because politicians constantly try to convince voters otherwise. To
paraphrase Thomas Sowell:
"The first law of economics is that there’s no such thing as a free lunch; the first law of politics is to disregard the first law of economics."
Politicians convince only the naive that government
can provide free benefits, but the political process creates a lot of naivety.
This naivety in turn allows politicians to enact policies that make it rational
for consumers to act as if they believe government has lowered
the cost (often to zero) of goods even when they know better. As the joke
suggests, however, the more the “as if” cost of a good is reduced, the more its
real cost is increased. This can be explained by making use of the important
distinction between the total cost consumers pay for a good and the marginal cost
they pay—that is the additional amount they pay to buy one more unit of the
good.
The most obvious way the government can make people
act as if the cost of a good has been reduced is
to lower its price. The most direct way to do that is by imposing a price
ceiling below the market price. We mention a price ceiling briefly only to
explain why we do not consider it in detail. When the price of a good is
legally lowered, the amount supplied will decrease, so consumers cannot act as
if the cost has been lowered by purchasing more, despite their desire to do so.
Also, it quickly becomes clear to consumers, once the aggravation of longer
lines, poorer service, and declining quality is considered, that the cost of
the good has become higher, not lower.
A more lasting way for politicians to give the
impression they have lowered the cost of a good is to subsidize its supply.
This can be done by transferring an amount covering all or part of the cost to
suppliers for every unit of a good sold to consumers. This per-unit subsidy
would cause a corresponding drop in the cost of production and thus in the
price of each unit of the good. We assume the supply curve is horizontal—that
is, prices won’t rise to offset increased consumer purchases in response to the
price subsidy.
For example, the entire cost of providing a year of K-12 government schooling is subsidized, and parents can send all their children to a government school regardless of how many they have. There are, of course, restrictions on which school parents can send their children to, and they have little control over who teaches their children. Similarly, government medical care subsidies, whether provided through Medicaid, Medicare, or tax advantages bestowed by not taxing employer-provided insurance as income, lower the price paid directly for medical care. Here again, relatively few restrictions on the amount of medical care people demand have been imposed, but this is likely to change rather significantly in the future.
If they give it any thought, most people recognize
that any market prices they pay directly for government schooling and medical
care are far less than the total amount they actually pay for these services.
But they seldom know how much they are paying over and above the direct
out-of-pocket price, and even if they did, it would not influence how much of
the subsidized services they demand. This begins the explanation of why
subsidizing goods increases their cost.
When politicians subsidize the supply of a good, they
reduce its marginal cost to consumers by increasing the amount they pay in
taxes to finance the subsidy. The marginal cost—the additional amount paid when
another unit is purchased, as determined by the now-lower price—is the only
cost consumers pay attention to. The total subsidized cost, in the form of
higher taxes and/or insurance premiums, also increases when a consumer buys
another unit of the service, but that increase is spread over all consumers,
often many millions of them. So the increase in this cost is effectively zero
to a consumer deciding how much of a subsidized good to buy, and is therefore
ignored.
In other words, subsidizing the supply of a good
creates an external cost of the type that is referred to as a “market failure”
when it results from private activity (think of pollution, which is really the
result of the absence of markets), but is referred to as protecting consumers
against market exploitation when intentionally created by government policy.
The subsidy creates a situation in which each consumer can benefit by shifting
much of the cost of her consumption to the rest of the population—the larger
the subsidy the larger this external cost. The result is excessive consumption
of the subsidized good as each consumer expands her consumption beyond the
point where the marginal value she receives becomes less than the marginal cost
of producing the good—that is, less value is received from additional units
than is sacrificed to produce them.
Some argue that subsidizing certain goods is justified
because their production and/or consumption generate external benefits and
would therefore be underconsumed if not subsidized. It is possible that a
government subsidy can increase consumption of a good by exactly enough to
offset the underconsumption due to an external benefit that would otherwise
exist. But a realistic view of the knowledge political authorities possess, and
the incentives they face, raises serious doubt that such goods can be correctly
identified, or the right subsidy applied if they were. For example, there are private
firms that generate both external costs (say in the form of pollution) and
external benefits when producing a good. It is easy to model a situation in
which efficiency requires that such a firm’s production should be subsidized
despite the pollution it creates. However, we challenge any government agency
to determine when such situations exist, as they surely do, and then accurately
determine what the efficient subsidies are. And even if such information were
available, it would be largely ignored since the political considerations that
determine what goods are subsidized, and by how much, seldom have much if
anything to do with economic efficiency.
The point is that no matter why government subsidizes
a good, whether to improve economic efficiency or, more likely, to satisfy some
constituency under the pretense of reducing the good’s cost, the effect is
invariably to increase its cost. Even though the immediate effect is to
decrease the good’s price by the subsidy’s per-unit amount, with the per-unit cost
(price plus the cost of the subsidy) remaining the same, the lower price will
quickly motivate an increase in the amount demanded. This will cause the price,
and therefore the per-unit cost, to increase for at least three reasons, even
if, as we have assumed, the supply curve is horizontal.
First, consumers have little motivation to shop
carefully because the price, or direct cost, is often a small percentage of the
total cost. In some cases, such as government schools (where the price is
zero), consumers typically are not allowed to compare alternatives, but are
assigned to a particular supplier (school). Even when consumers can choose
their suppliers, they have little motivation to ask about the cost of the good,
as is the case of medical care—the direct cost of which is only about 13
percent of the total cost in the United States. With consumers paying little
attention to the cost of the goods they consume, suppliers have less motivation
to compete on price and greater latitude to direct their customers into costly
options that add little if any value.
Second, the less of the total cost consumers pay
directly for a good, the less control they have over its quality or the
convenience with which it is delivered. The result is that the quality of
subsidized goods declines relative to their increased cost. Indeed, government
schools provide a clear example of declines in educational quality,
particularly in the inner cities where parents are less able to afford private
schools, while cost has increased significantly. By most measures the quality
of American medical care has improved, as access to improved drugs and the
availability of technically advanced medical devices have increased, but at a
greater cost than necessary. And the extra cost has not resulted in life
expectancies equal to those in some countries with lower per-capita spending on
health care, although there are many factors other than such spending that
affect life expectancy. And it should also be pointed out that in countries
where medical care is provided by the State, there are longer waits for that
care than in the United States.
What can be said with confidence is that the control
people have over the medical care they receive is becoming more like the
control pets have over the medical care they receive. In both cases, the ones
receiving the care are not the ones paying directly for it. Doctors consider
those paying directly their customers, and primarily cater to their desires
(and instructions).We might have some advantage over our pets in this regard
since we still pay directly for a portion of our care. But when considering our
diminishing control over health care decisions that affect our lives, we should
ask ourselves: Are the bureaucrats representing those paying for most of our
medical care as concerned with our well-being as we are for the well-being of
our pets?
A third reason why subsidizing goods increases their
cost is the burdensome red tape that invariably accompanies the production and
consumption of such goods. It is customary for people to complain about the
forms that have to be filled out and records that have to be kept by teachers
and their students, and doctors and their patients. There is also the
accompanying cost of the hoards of bureaucrats necessary to formulate, enforce,
and keep records on all the rules and regulations, most of which have no
obvious connection with doing a better job educating and healing. But such
complaints, and the promises of politicians to reduce red tape, have no effect
because there is a good reason for much if not all of it. One of the
unappreciated advantages of market exchanges is that when consumers pay with
their own money and suppliers have to compete for that money by producing
value, people are motivated to make decisions that benefit others. This market
accountability is destroyed when suppliers are being paid by third parties for
most of the cost of making a good available to consumers. Red tape is a poor
substitute for market accountability, as is evident from the fact that it does not
prevent the cost of subsidized goods from increasing. But if markets are not
allowed to function, the alternative to red tape would be an almost complete
lack of accountability. The only way to reduce red tape is to eliminate the
subsidies and restore the effective and efficient accountability that only a
market can impose.
Even though most of the cost of a subsidized good is
paid indirectly, it commonly increases to the point where there is a noticeable
and negative public reaction. When this happens, the political response to
public complaints about the escalating cost is almost always to increase the
subsidy, not to reduce or eliminate it. This will be accompanied by political
attempts to convince the vast majority that a relatively few rich taxpayers
will pay the subsidy thanks to efforts to make them “pay their fair share.” The
reality is that almost everyone ends up paying more one way or another. The
total cost continues to go up, as do the inconvenience and red tape imposed on
consumers and suppliers by government, which then provides more jobs for both
government and private-sector bureaucrats.
When the cost-increasing effects of ever larger
subsidies overwhelm the ability of politicians to convince voters that the cost
is being paid primarily by others, political efforts are made to reduce the
cost. But these efforts typically involve more bureaucratic control, which
imposes yet more restrictions on the types of goods and services available, who
is eligible to receive particular types, and the amount of compensation
received by suppliers.
This has clearly been the case with health care. Since
government began to provide significant health care subsidies, reform has
consistently meant increasing the size and scope of the subsidies and the
legislative detail imposed on health care decisions. It is interesting to note
that physicians experienced large income increases with the big boost in
medical subsidies beginning in 1965 with Medicaid and Medicare. Their increased
compensation was part of the general increase in medical costs as consumers
became less concerned with the cost of their care and demanded more of it. Not
surprisingly, physicians are less enthusiastic about the 2010 Affordable Care
Act, which is threatening to reduce their incomes. But consumers have the most
to lose from increased government control over health care decisions. Without
market prices determined by free exchange and undistorted by government
subsidies, goods will have to be rationed by government authorities. They won’t
be called death panels, but they will be making decisions that will result in
shovel-ready action.
The experience in government education is different
from that in medical care for the obvious reason that it has long been financed
entirely by government subsidies. Therefore, cost increases in government
education cannot be obscured with increased subsidies. Also, school choice has
been far more limited than the choice of doctors and hospitals. This may be why
providing consumers more choice has been recommended as the best way to reduce
educational cost and improve its quality. Privatizing schools would be the most
effective way of achieving these improvements by insuring that people are
paying the full cost of education directly with their own money. A clearly
second-best approach would be providing parents of school-age children
educational vouchers that could be used to pay for tuition at any school,
private or public, that parents chose. Even this second-best approach has been
effectively resisted by the government-school lobby, which has so far been able
to convince the public that competition would reduce the quality of education.
Fortunately, more people are starting to see this lobby as the biggest obstacle
to genuine educational reform.
Most people would like to have their purchases
subsidized by government. Once we start down that road, however, it is hard to
keep the subsidies from spreading to a wide variety of things almost everyone
purchases. The result is we find ourselves heading toward the situation
described by Frédéric Bastiat, the nineteenth-century economist, when he said,
“The state is the great fictitious entity by which everyone seeks to live at
the expense of everyone else.” Such an attempt to reduce the cost to everyone
is clearly a guaranteed way to increase the cost of everything. If you think it
is expensive now, just wait as the politicians continue to disregard the first
law of economics.
