Arnold Kling, with his characteristic deep insight, recently described
“the straw-man argument against libertarianism and for technocracy.”
This straw-man argument has, Kling explains, the following steps:
1. Libertarianism relies on markets.
2. Markets are optimal only under conditions of perfect competition.
3. The conditions for perfect competition are rarely satisfied.
4. There are many instances of market failure.
5. Therefore, libertarianism does not work.
Kling then adds:
Step (2) is a swindle. It
sneaks in the assumption that markets have to be optimal in order to be
preferable to government intervention.
Instead, long ago I
offered the aphorism “Markets fail. Use markets.” That is, I readily
concede that the market economy is not at some theoretical optimum. The
question is what will lead to improvement. I believe that government
intervention will often make things worse. Meanwhile, entrepreneurial
innovation and creative destruction tends to solve economic problems,
including market failures.
One of the commenters on Kling’s post, Matt Gelfand, then offered the following:
Let’s flip Arnold’s line of reasoning around to examine the merits of government action.
1. Government action relies on government actors behaving in the public interest.
2. Governments are optimal only under conditions of perfect altruism of government actors.
3. The conditions for perfect government are rarely satisfied.
4. There are many instances of government failure.
5. Therefore, government does not work.
There
are many examples of market failure that cannot be overcome by
libertarian market processes, and I believe libertarians would agree
with at least some of them. They usually involve “public goods” where
competitive actors would be duplicative and inefficient. Thus, a system
of laws, the justice system, national defense, public safety (police,
fire firefighters), airline safety, and numerous other examples are more
efficiently handled through the polity rather than markets.
Despite at least one of commenter Gelfand’s examples of ‘good’
government actions (namely, regulation of airline safety) being highly
dubious, my purpose here isn’t to challenge the listed examples of
‘good’ government action. Instead, I’ll argue that Mr. Gelfand, like
many others, mistakenly assumes that the market and government are
symmetrical to each other in a way that they are not.
Of course, any desired outcome can, in principle, be pursued either
with voluntary action (the market, broadly conceived) or with coercive
action (government). In this simple way the market and government are
indeed symmetrical to each other. But there the symmetry ends. The logic
of the market’s operation differs categorically from the logic
of government’s operation. These differences are rooted in, but extend
beyond, the fact that only in markets is all action voluntary.
The single most important difference separating market action from
government action is this: Unlike decision-makers in government,
decision-makers in markets have access to detailed and reasonably
reliable information about the net effects that any of their decisions
are likely to have on all affected parties. In addition, decision-makers
in markets also are uniquely incited to take those actions, and only
those actions, that produce the largest possible positive net effects on
affected parties.
The fact that the information available in markets is imperfect is
indisputable. Also indisputable is the fact that even well-informed
market actors often err. But equally indisputable, if not as widely
recognized, is the reality that markets have (as an essential feature of
their operation) a built-in process for detecting and correcting error,
and thus taking into account over time as much relevant knowledge as
possible. No such process exists in government. Because of this
categorical difference, any supposed substantive symmetry between
market action and government action is imaginary.
The foundational (if not the only) advantage of relying upon markets
rather than upon government to supply, say, shoes is that only in
markets is there a reliable source of information about which varieties
of shoes to produce and how to produce these varieties efficiently –
that is, how to produce these varieties of shoes in ways that leave as
many resources as possible available for the production of goods and
services other than shoes.
The amounts of their incomes that consumers choose to spend on Crocs,
Nike sneakers, and Gucci loafers registers the intensity of consumers’
demands for each of these kinds of shoes relative not only to consumers’
demands for other kinds of shoes but also relative to their demands for
all other goods and services available for sale.
The prices of each of the different varieties of shoes convey at
least two critical pieces of information. First, the prices of Crocs
tell entrepreneurs just how much consumers are willing to pay for Crocs
compared to how much consumers are willing to pay for sneakers and
loafers, and compared also to how much consumers are willing to pay for
hamburgers, honey, housing, books, bananas, baseballs, and every other
good or service currently for sale on the market. Second, the prices of
Crocs relative to the prices of the inputs that might be used to produce
Crocs tell entrepreneurs both if consumers’ desire for Crocs
is high enough to justify using resources to produce Crocs, and, if so,
just how many pairs of Crocs to produce.
If, as is usual, there is some unexpected change in the market (for
example, consumers suddenly lose their taste for Crocs), consumers today
will not be served as well as possible. Ditto if entrepreneurs as a
group commit some error (for example, fail to notice the high consumer
demand for blue suede shoes). Too many resources today will be devoted
to producing Crocs while too few resources are used to manufacture shoes
of blue suede. As a result, the prices of Crocs will fall relative to
the prices of other goods and services, while that of blue suede shoes
will surely soon be noticed by profit-seeking entrepreneurs to be high
enough to justify increased production of this particular style of
footwear. Such price changes, and more accurate recognition of existing
prices, render what might be described as today’s inefficiencies (or
market ‘failures’) as, also, today’s profit opportunities. Guided by
prices, entrepreneurs will profit by shifting resources out of the
production of Crocs and into the production of other items, including
blue suede shoes.
Entrepreneurs who are insufficiently alert to market realities as
revealed in the prices of both inputs and outputs, or entrepreneurs who
are too incompetent to act profitably on market information, suffer
losses. These entrepreneurs thus wind up ‘controlling’ fewer resources,
with greater amounts of resources coming to be ‘controlled’ by
entrepreneurs who are more alert or more competent.
The self-interest of entrepreneurs combines in the market with the
self-interest of consumers and input suppliers – and also with the ability of consumers and input suppliers each to say ‘no!’
to offers they judge to be unattractive – to cause opportunities for
improving the allocation of resources to be revealed in market prices.
Again, such information is never revealed perfectly. Nor is it ever
acted on with only unalloyed expertise. But the very essence of the
market process is to reveal such information and to incite everyone in
the market to act on it.
No such process of information revelation is available for government action. Precisely because
government intervention into markets is intended to disregard or to
override market signals, government officials, if they are to improve
the welfare of citizens, must have access to information that is
superior to that which is available on markets. But government
officials, in fact, not only have no superior source of information,
they have no good source of information at all. The best they can do is
guess.
This absence of information available to government officials is an
especially acute problem for those officials who fancy themselves able
to improve the economy’s performance by nationalizing industries, by
using subsidies and protective tariffs, and by imposing ‘corrective’
taxes here and there. But this absence of information is ubiquitous
throughout all government affairs. No matter which projects government
undertakes as a government, its officials cannot really know, in the way
that market participants know, just what to produce, how much to
produce, and how best to produce it.
Even the local government that supplies policing services paid for
with tax dollars has no solid information about just how much policing
to supply and how best to supply these services. Consumers don’t express
their demands for government-supplied policing by voluntarily spending
money for it, with the ability to change the amounts they spend in
response to changes in the quality of, or the desire for, the service
provided. While grotesque government incompetence on this front might
prompt changes for the better, through the ballot box or through people
voting with their feet to move to other jurisdictions, for many compelling reasons
the sorts of information revealed in elections or by moving from
jurisdiction to jurisdiction have none of the details, nuance, richness,
or timeliness that characterize the information conveyed in markets.
Politically conveyed information is so thin, noisy, and out-of-date –
and, hence, so unreliable – as to differ categorically from
market-conveyed information.
As the policing example suggests, the lack of reliable information
available to government actors to use to carry out various tasks doesn’t
imply that there are no tasks appropriate for government to undertake.
Sometimes political instinct tells us that this or that task, if left to
private market forces, would likely be performed even worse than if it
is assigned to government. And sometimes this instinct might be correct,
although there’s no way to verify this conclusion.
Whatever is the case offered in support of government action, a
respect for honesty should compel those who make this case to admit that
government officials who carry out the prescribed action are neither
guided nor incited by the kinds of detailed information that guides and
incites market actors. Unlike actions taken in markets, even the best
government actions carried out in the most appropriate circumstances are
guided by little more than guesswork.
