In a recent post at the ThinkMarkets
blog, Freeman author Gerald P. O’Driscoll cited Union Pacific Railroad’s
labor woes as an example of the mismatch between the skills workers possess and
the skills potential employers are seeking. O’Driscoll argues that there has
been an unsustainable boom in “human capital” characterized by massive
malinvestments, just as Austrian economists typically claim for physical capital
goods. This perspective is a useful antidote to the Keynesian analysis of our
current slump and leads to radically different policy recommendations.
O’Driscoll based
his post on a Wall Street Journal report that referred to
“survey results showing that 83 percent of manufacturers reported a moderate or
severe shortage of skilled production workers. . . . Wages for skilled labor
are rising, in some cases at double-digit rates.”
He noted: “Malinvestment in labor markets is the counterpart to malinvestment in capital goods. Higher education is a bubble, and colleges churn out graduates with degrees that have no application in the workplace. Student borrowing to acquire such degrees is malinvestment in the same way that construction loans to build homes in Las Vegas was malinvestment.”
And here is his
policy conclusion: “There is no mechanism by which lowering interest rates
(‘monetary stimulus’) or spending money on public workers (‘fiscal stimulus’)
is going to cure the problem. Labor mismatch is a manifestation of a
coordination failure. . . . It is a microeconomic problem.”
O’Driscoll’s remarks underscore the stark theoretical contrast between today’s Keynesians and Hayekians as they approach “macro” problems, notwithstanding recent claims by Paul Krugman and others that Hayek’s contributions to the field were insignificant.
Today’s economic
problems do not emanate primarily from a shortfall in aggregate spending but
rather from a poor synchronization among all the millions of individual
productive inputs (including labor) that typically interact seamlessly to
support our fantastic standard of living. Once we recognize this as the
fundamental problem, the standard Keynesian medicine turns out to be not merely
a placebo but a poison.
In the traditional
exposition by Ludwig von Mises and F. A. Hayek, the Austrian theory of the
business cycle explains recessions as the inevitable consequence of a preceding
inflationary boom. The boom occurs when the commercial banks (nowadays acting
in concert with the central bank) issue new loans even though the public isn’t
saving more, thereby increasing the quantity of money and driving the interest
rate below its “natural” level. The lower interest rates—“cheap money”—foster a
feeling of euphoria, as businesses invest more and households consume more.
The Austrians
argue that the boom is illusory because the banks can’t create genuine
resources simply by extending loans on their balance sheets. If the economy had
previously been in a sustainable equilibrium, it will now be “growing” on an
unsustainable trajectory.
When mainstream
economists hear the Mises-Hayek explanation of the boom-bust cycle, they often
characterize it as an “overinvestment theory.” Yet Mises himself took pains
in Human Action (chapter 20) to clarify that this wasn’t the
case:
The
erroneous belief that the essential feature of the boom is overinvestment and
not malinvestment is due to the habit of judging conditions merely according to
what is perceptible and tangible. The observer notices only the malinvestments
which are visible and fails to recognize that these establishments are
malinvestments only because of the fact that other plants—those required for
the production of the complementary factors of production and those required
for the production of consumers’ goods more urgently demanded by the public—are
lacking.
Mises goes on to
make his famous analogy, which remains the best metaphor yet for his theory:
The whole
entrepreneurial class is, as it were, in the position of a master builder whose
task it is to erect a building out of a limited supply of building materials.
If this man overestimates the quantity of the available supply, he drafts a
plan for the execution of which the means at his disposal are not sufficient.
He oversizes the groundwork and the foundations and only discovers later in the
progress of the construction that he lacks the material needed for the
completion of the structure. It is obvious that our master builder’s fault was
not overinvestment, but an inappropriate employment of the means at his
disposal.
In a standard
neoclassical growth model we could meaningfully speak of “overinvestment”
leading to suboptimal results. Specifically, if people for some reason (perhaps
because they were cajoled by government policies) save a higher fraction of
their income than they would have chosen in a neutral setting, then capital
goods will accumulate at a faster rate, and gross domestic product (GDP) will
grow at a faster rate.
However, this
outcome is a bad thing—as judged by the real preferences of the households in
the model—because the higher investment and faster growth are achieved at too
high a price in forfeited consumption in the present and near future. If an
eccentric gangster has a standing threat to blow up a family-owned business
unless it reinvests 99 percent of the profits for ten years straight, on paper
the business may actually prosper, but the family members are clearly harmed by
the arrangement.
Yet this type of
overinvestment isn’t at all what Mises and Hayek have in mind when discussing
the unsustainable boom. As the quotations from Mises illustrate, the
fundamental problem is not that society (during a boom) leans too heavily to
the left side of the investment/consumption spectrum. Rather the problem is
that the investments are not in sustainable lines.
The Wrong Tools
To give an
exaggerated example, mainstream economists—by classifying the Austrian theory
as one of “overinvestment”—have in mind that businesses produce too many tools
and not enough pizzas. Yet this type of mistake wouldn’t require a recession;
it would simply mean that consumers would be trading off present enjoyments
(which they valued more, by stipulation) for a higher income in the future made
possible by the productivity-enhancing tools.
Rather than being
about making too many tools and not enough pizzas, the Austrian story is more
about businesses producing tools consisting only of thousands of screwdrivers
and millions of nails. For a short while, especially if we just focused on a
few of the factories, such an absurd economy would seem very “productive”
indeed, poised on the verge of explosive growth. But from a systemwide
perspective it is obvious this economy would soon collapse once its existing
tools wore out and workers had to rely on the new batch. When the crisis
occurred it would be wrong to characterize the problem as one of “too much
investment in tools.” The fundamental problem would be malinvestments in the
composition of the stock of new tools.
Idle Resources
Because they lack
the Austrian emphasis on the structure of production, Keynesian economists look
at idle resources, or “excess capacity,” during a recession and see pure waste.
Of course the market economy is malfunctioning if factories
are running below capacity and especially if workers are sitting at home
watching TV. This is why (the Keynesians claim) a recession calls for
expansionary fiscal and monetary policies to increase aggregate spending and
put those resources back to work.
This simple-minded
view is dead wrong in light of the Austrian explanation. Continue with Mises’s
master builder, who embarks on construction of a house using blueprints that
rely on an erroneous brick count. When the builder discovers his error—he
realizes he only had 18,000 bricks in the beginning instead of the 20,000
called for by the blueprints—what will be his immediate reaction? He will yell,
“Everybody stop working!”
The reason for
this immediate stop order is clear. If every worker continued in what he had
been doing, the dwindling stocks of various resources (bricks, shingles, nails,
window panes, and so on) would have been transformed into less “liquid” items.
The builder obviously has to adjust the blueprints in light of the new
information; it is physically impossible to complete the house as originally
conceived. Therefore he needs to halt all activity until he decides the best
way to deploy the remaining inputs, all things considered.
Reintegration
Eventually more
and more of the workers can gradually resume activity, but many of them won’t be
doing exactly what they were doing before, and some of them
might be doing very different tasks. Also, some of the workers who were highly
specialized might not be needed at all for the remainder of the project. It
made sense for them to show up at the site based on the original blueprints,
but after the necessary revisions the master builder realizes these particular
workers serve no role.
The analogy with a
modern economy should be clear. When an unsustainable boom collapses there is
an initial surge in unemployment of both human and physical resources.
Gradually—especially if the government leaves the market process to operate
freely—more and more resources are reintegrated into the (revamped) structure
of production. The process unfortunately might be agonizingly slow for some
resources and workers with highly specialized skills.
Notwithstanding
the tragedy of high unemployment, it is a necessary consequence of a preceding
inflationary boom. Austrians stress that the boom is the
problem; the bust is ironically the cure. Like many types of
medicine, recessions are not nearly as enjoyable as the activities that brought
on the calamity.
Considerations
such as these led O’Driscoll to describe our current economic woes as
“microeconomic.” Think again of the master-builder analogy. Before the
discovery of his mistaken brick count the problem wasn’t that the builder was
“building too aggressively.” It was that he was building a house with the wrong
proportions. Then, after the discovery of his mistake, the problem wasn’t that
the builder was “building too timidly.” Instead, the problem—if we want to call
it that—was that the remaining stocks of usable resources were ill-suited to
complete the half-finished house.
In the
master-builder metaphor the analog of expansionary policies would be to
reassure the builder that his brick count is accurate after all. For example, a
subordinate might not want the workers to “lose morale” and so he might keep
moving tarps around, covering up the dwindling brick supply and lying to the
master builder about how many remain. This would keep the “good times” rolling,
at least for a while. Yet it will just make the crisis that much worse when it
finally arrives, as it must. Moving tarps around can’t create more bricks, just
as moving bad loans around with TARP can’t create more physical resources.
We’ve seen that
even the canonical exposition of Austrian business cycle theory involved labor,
as it must if it is to explain high unemployment. However, the typical
Mises/Hayek story focused on malinvestments in physical capital goods, which
eventually led to high unemployment in the labor market. The twist O’Driscoll
gives is that the original malinvestments during the boom period might
themselves be in “human capital.”
Boom Builders
Some of this
malinvestment can be tied directly to the housing boom. Just as too many nails
and shingles went to Las Vegas and Miami from 2002–06, so did too many human
beings move to these cities and spend years developing skills in home
construction. When the housing bubble popped, the nails and shingles had been
irrevocably devoted to houses that never should have been built, while hundreds
of thousands of workers had a difficult-to-modify skill set that never should
have been learned.
There was a
similar toll in financial services. During the giddy years top-flight students
with an aptitude in mathematics were drawn out of physics and other scientific
fields and flocked to Wall Street to become rich as “quants.” In retrospect we
now realize that some of the brightest minds on the planet had literally spent
years working grueling schedules to (in effect) devise various techniques to
amplify the financial fallout from an economic downturn. This was hardly an
optimal use of scarce labor.
As O’Driscoll
notes, even higher education itself can be viewed as an unsustainable bubble in
light of Austrian theory. The false prosperity of the boom years led to large
increases in education budgets, fostering erroneous expectations of how many
jobs would be available for future Ph.D.s in the “soft sciences” and other
fields that do not have a market outside academia.
The Austrian
theory of the business cycle shows how monetary disturbances can lead to
“real” imbalances in the structure of production. The classical version of the
theory focused on malinvestments in physical capital goods, but the theory can
easily be amended to include the unsustainable development of human capital. In
either case the best government response is to eliminate the subsidies,
low-interest loans, and other policies that encourage the very problems under
consideration.
