And unlike some disciplines, which acknowledge that there’s a huge gap between
the scholarly knowledge and policy advice, economists have been anything but shy
about asserting their authority.
As we can see from the current dismal state of economic affairs, economies
are incredibly complex systems, and policymakers who are forced to act in the
face of this uncertainty and complexity want guidance. And over the last half
century, neoclassical economists have not only been more than happy to offer it,
but largely been able to marginalize any other disciplines or approaches, giving
them a virtual monopoly on economic policy advice.
But there are two big problems with this. First, despite economists’ calming
assurances, we still know little about how economies actually work and the
effect of policies. If we did, then economists should have sounded the alarm
bells to head off the financial collapse and Great Recession. But even more
problematic, even though most economists know better, they present to the
public, the media and politicians a simplified, vulgar version of neoclassical
economics — what can be called Econ 101 — that leads policymakers astray.
Economists fear that if they really expose policymakers to all the
contradictions, uncertainties and complications of “Advanced Econ,” the latter
will go off track — embracing protectionism, heavy-handed “industrial policy” or
even socialism. In fact, the myths of Econ 101 already lead policymakers
dangerously off track, with tragic results for the economy and everyday
Americans.
Myth 1: Economics is a science.
The way economists maintain stature in public policy circles is to present
their discipline as a science, akin to physics. In Econ 101, there is no
uncertainty, only the obvious truths embedded in supply and demand curves. As
noted economist Lionel Robbins wrote, “Economics is the
science which
studies human behavior as a relationship between given ends and scarce means,
which have alternative uses.” If economics is actually a science, then
policymakers can feel more comfortable following the advice of economists. But
if economics is really a science – which implies only one answer to a particular
question — why do 40 percent of
surveyed
economists agree that raising the minimum wage would make it harder for people
to get jobs while 40 percent disagree? It’s because as Larry Lindsey, former
head of President Bush’s National Economic Council, admitted, “the continuing
argument [among economists] is a product of philosophical disagreements about
human nature and the role of government and cannot be fully resolved by
economists no matter how sound their data.”
Myth 2: The goal of economic policy is maximizing
efficiency.
Economists have one overarching principle that shapes their advice: maximize
“efficiency.” As economist and venture investor William Janeway notes,
“Efficiency is the virtue of economics.” But the goal of economic policy should
not be to maximize static efficiency (the “right” allocation of widgets), but to
create inefficiency — in the sense of disruptive innovation that makes widgets
worthless. For it is the development of new widgets and better ways to make them
(e.g., innovation), rather than efficiently allocating existing widgets, that
drives prosperity. As noted “innovation” economist Joseph Schumpeter pointed
out: “A system which is efficient in the static sense at every point in time can
be inferior to a system which is never efficient in this sense, because the
reason for its static inefficiency can be the driver for its long-term
performance.”
Myth 3: The economy is a market.
In the world of Econ 101, “the economy” is usually treated as a synonym for
“the market.” But an enormous amount of economic activity takes place outside of
competitive markets dominated by for-profit, private firms.
In the industrial nations of the OECD, government spending at all levels on
average accounted for 46 percent before the Great Recession. Even in capitalist
countries, the government is usually the largest employer, and the largest
consumer of goods and services in areas like defense, education and
infrastructure. Other non-market sectors responsible for goods and services
production include the household (your chores are economic activity too, even if
Econ 101 ignores them) and nonprofits like religious institutions, colleges and
universities, charities and think tanks like ours. Markets, then, account for
around half of a modern nation’s economic activity — maybe less, if uncounted
household production is as big a part of the real economy as some have
claimed.
Myth 4: Prices reflect value.
If the economy is a market, prices are what allow goods and services to be
efficiently allocated. In Econ 101, because prices are set in “free markets,”
the price of something must be a reflection of its real value. This principle —
known as the efficient market hypothesis — was the reason why, when in the
run-up to the Great Recession real house prices increased 40 percent (a more
than seven-fold increase from decades prior), virtually no economist sounded the
alarm, precisely because those higher prices must have reflected higher value.
This is why Ben Bernanke stated in 2005 that rising home prices “largely reflect
strong economic fundamentals” and Fed chairman Alan Greenspan assured us that,
“It doesn’t appear likely that a national housing bubble, which could pop and
send prices tumbling, will develop.” Had economists not been in the grip of the
efficient market hypothesis, they would have realized that something was
seriously amiss and helped rein in lending to reduce the bubble and subsequent
collapse. But if they tell policymakers that prices don’t always reflect value,
then the entire foundation of Econ 101 starts to crumble.
Myth 5: All profitable activities are good for the
economy.
Another axiom of Econ 101 is the assumption that all profitable activities
are good for the economy: After all, Adam Smith “proved” that pursuit of
self-interest maximizes economic welfare. To be sure, even Econ 101 would
recognize that societies use legal penalties to discourage economic transactions
like prostitution and drug use that are considered immoral, to say nothing of
Mafia contract killing.
But the version of Econ 101 familiar to most politicians and pundits ignores
the distinction between productive activities (e.g., making useful appliances or
lifesaving vaccines) and pure rents (profiting from real estate appreciation,
stock manipulation or the accident of owning mineral deposits that become more
valuable). If the greatest fortunes are to be made in financial arbitrage,
gambling in real estate or exploiting crony-capitalist political connections,
the argument that private profit-seeking maximizes economic welfare and the
public good is undermined.
Myth 6: Monopolies and oligopolies are always bad because they
distort prices.
In the abstract universe of Econ 101, monopolies and oligopolies are always
bad because they distort prices. Here populism, often opposed to neoclassical
economics, is allied with it. The neoclassical vision of the normal economy with
multiple small yeoman producers resonates with Jeffersonian antitrust policy,
with its suspicion that all large enterprises must be conspiracies against the
public.
In the real world, things are not that simple. Academic economics includes a
well-developed literature about imperfect markets. But it is reserved for
advanced students and is never encountered by those who are told only the
simplicities of Econ 101. In manufacturing industries with increasing returns to
scale, like semiconductor or airplane production, markets characterized by a few
large producers are usually more productive and innovative than ones with many
small producers. The same is usually true in industries characterized by network
effects, like railroads or communications infrastructures such as wired or
wireless broadband. And as Joseph Schumpeter pointed out, temporary monopolies
based on technological innovation are not only beneficial but are key enablers
of seeding further innovation — particularly if the “innovation rents” or
super-profits are funneled back into R&D.
Myth 7: Low wages are good for the economy.
According to Econ 101, high wages are bad for an economy and low wages are a
blessing. James Dorn of the libertarian Cato Institute declares that higher
wages, by causing less demand for workers, mean that “unemployment will increase
… No legislator has ever overturned the law of demand.” High-wage countries, we
are told, price themselves out of a supposed global labor market. And in the
non-traded domestic service sector in which most Americans work, a higher
minimum wage, Econ 101 claims, would lead to permanent higher unemployment.
When it comes to traded goods and services, this ignores the effects of
relative currency values being the major determinant of prices of exports and
imports. It also ignores the fact that high-wage workers who are highly
productive, thanks to their machines and skills, can produce more cheaply than
poorly paid workers with inferior technologies and skills. According to the
Asian Development Bank, most of the high-value-added components of iPhones,
which are assembled in China, actually come from high-wage nations like Germany,
Japan, South Korea and the U.S. Michael E. Porter and Jan Rivkin state flatly
in the Harvard Business Review: “Low American wages do not boost
competitiveness,” which they define to mean that “companies operating in the
U.S. are able to compete successfully in the global economy while supporting
high and rising living standards for the average American …” The countries that
beat the U.S. in the latest competitiveness rankings by the World Economic Forum
are all high-wage nations: Switzerland, Singapore, Finland, Sweden, the
Netherlands and Germany.
In industries that cannot be outsourced, labor is only one of several factors
of production that can be substituted for one another. Writing in defense of
low-wage immigrant farmworker programs in the progressive magazine Mother Jones,
Kevin Drum claims: “Most Americans just aren’t willing to do backbreaking
agricultural labor for a bit above minimum wage, and if the wage rate were much
higher the farms would no longer be competitive.” But if American farmworkers
were paid better, then U.S. agribusiness would have an incentive to cut costs
using technology, like automated tomato picking machines, as the agricultural
sectors of Japan, Australia and other high-wage nations have done. While
transitional unemployment as a result of innovation always has to be dealt with,
the effects of high wages in encouraging investment in labor-saving technology
should be welcomed, not deplored.
Myth 8: “Industrial policy” is bad.
Econ 101 tells us that letting markets determine how many “widgets” to
produce maximizes efficiency. The worst thing government can do is engage in
“industrial policy” — a catch-all pejorative used to discredit everything from
funding solar energy companies to encouraging more college students to major in
science. As former Bush economic adviser Gregory Mankiw stated: “Policymakers
should not try to determine precisely which jobs are created, or which
industries grow. If government bureaucrats were capable of such foresight, the
Soviet Union would have succeeded.” In other words, how can government
bureaucrats make better choices than business? Leaving aside the fact that banks
issued trillions of dollars of bad loans leading to the financial crisis, for
many investments private and public rates of return differ, often quite
significantly. And unless society (through government) tilts investment to those
activities where the public rate of return is higher (e.g., scientific
research), growth will be less. If this is industrial policy, so be it.
Myth 9: The best tax code is one that doesn’t pick
winners.
Econ 101 disparages industrial policy, even, or perhaps especially, when it
is used in the tax code. Economists call anything other than a completely
neutral tax code “distortions,” “special interest tax breaks,” “corporate
welfare” or, as the Simpson-Bowles Commission labeled them, “perverse economic
incentives instead of a level playing field.” Economists disdain tax incentives
because in the words of the Obama administration’s Recovery Advisory Board,
“certain assets and investments are tax favored, tax considerations drive
overinvestment in those assets at the expense of more economically productive
investments.” But as Canadian Treasury economist Aleb ab Iorwerth writes,
“Distortions that favor the contributors to long-run growth will be
welfare-enhancing.” In other words, tax “distortions” like the R&D tax
credit or accelerated depreciation for investments in new equipment lead to more
growth since these investments are more productive than others and have
significant positive externalities.
Myth 10: Trade is always win-win.
That trade always benefits both parties is perhaps the most fundamental dogma
that people take away from their Econ 101 courses. In discussing trade theory
with students and politicians, academic economists use fairy tales rather than
history. There is the fairy tale about comparative advantage: England was good
at producing wool, Portugal wine, so they trade and both are better off. There
is the fairy tale about how because market transactions are always voluntary and
always beneficial that trade, being simply a market transaction across borders,
is always win-win.
But Econ 101 never explains how nations like America, Britain, Germany and
Japan have used national industrial policies over the past century to become
industrial powerhouses. And Econ 101 never explains how foreign mercantilist
practices, like those China is embracing, can hurt the U.S. economy.
Higher-level students are sometimes introduced to the complexities of real-world
trade, but academic economists fear that sharing nuances with the general public
would unleash an epidemic of know-nothing protectionism.
But for most of the production of traded goods and services, comparative
advantage is meaningless – the Koreans and Japanese are not good at making flat
panel displays because they have a lot of sand, they are good at it because
their corporations and governments targeted it for competitive advantage.
Moreover, corporations locate their subsidiaries in particular nation-states to
take advantage of local government subsidies and tax breaks or increasingly
because of government requirements to produce locally. Econ 101 to the contrary,
the location of factories and innovative research complexes is not determined by
comparative advantage. Increasingly it is the artificial outcome of negotiations
among multinational corporations and territorial states. And the outcome of
this “free trade” can be detrimental to the U.S. economy if it hurts, as it has,
key U.S. high value-added industries.
Conclusion
When the U.S. economy faced little competition and was largely based on
industrial mass production industries, it was perhaps not so bad that
policymakers relied on Econ 101 as their guide to economic policy. But in a
complex, global, technologically driven economy in which nation-states compete
to capture markets and key links in global supply chains, relying on Econ 101 is
like a physicist today relying on Newton. It’s time for economists to fess up
and admit that theirs is not a science and that what passes for Econ 101 is
largely misleading. But the public, the media and politicians shouldn’t wait,
for it may be a long, long time coming. Rather, they need to understand that a
dumbed-down Econ 101 version of neoclassical economics no longer should serve as
a road map for economic policy.
