Economics Without Statistics
January 1, 2012
We often imagine the study of economics today to be mostly about
manipulating statistics. However, that is a new phenomenon. Today's
government-compiled statistics are mostly a post-World War II
phenomenon. This fascination with statistics is really an outgrowth
of the statist trend of economics in those days, particularly the
explosion of Keynesian economic management fads.
Before 1950, governments didn't really have much in the way of
statistics. What existed was often compiled by academics. Maybe this
was a good thing?
Consider, for example, Sir John Cowperthwaite, who was Hong Kong's
Financial Secretary from 1961 to 1971. Cowperthwaite is generally
recognized as a premier architect of Hong Kong's amazing success
since 1950.
What was Cowperthwaite's primary suggestion for other countries that
wanted to follow Hong Kong's path?
Asked what is the key thing poor
countries should do, Cowperthwaite once remarked: "They should
abolish the Office of National Statistics." In Hong Kong, he
refused to collect all but the most superficial statistics,
believing that statistics were dangerous: they would led the state
to to fiddle about remedying perceived ills, simultaneously
hindering the ability of the market economy to work. This caused
consternation in Whitehall: a delegation of civil servants were
sent to Hong Kong to find out why employment statistics were not
being collected; Cowperthwaite literally sent them home on the
next plane back.

This might seem odd, but one of the characteristics of Keynesian
central planning, or what we know as "mainstream economics" today is
an excessive fixation on statistics like GDP or the unemployment
rate. This tends to lead to various measures to jigger the
statistics, often in ways that don't fix any underlying problems,
and often make problems worse. Two such examples are aggressive
government deficit spending and, closely related, the expansion of
government employment in the face of declining private sector
employment.
You don't really need GDP statistics to know if the economy is doing
well or not, or if there is adequate job creation. This should be
readily apparent from anecdotal data, talking with businesspeople,
and so forth.

Abstract:
Expectations and information about the growth of GDP per capita
have a large influence on decisions made by private and public
economic agents. It will be argued here that GDP (per capita) is
far from a robust indicator of social welfare, and that its use as
such must be regarded as a serious form of market and government
failure. This article presents an update on the most important
criticisms of GDP as an indicator of social welfare and economic
progress. It further examines the nature and extent of the impact
of GDP information on the economy, revisits the customary
arguments in favour of the GDP indicator, and critically evaluates
proposed alternatives to GDP. The main conclusion is that it is
rational to dismiss GDP as an indicator to monitor economic
progress and to guide public policy. As is clarified, this
conclusion does not imply a plea against growth, innovation or
national accounting.

What if you didn't compile the hypercomplex "Consumer Price Index"?
Governments got by without it for centuries. In that case, you would
probably focus a lot more on stable
money, which has always meant a gold standard system. Let
prices take care of themselves. Most of these efforts to compile
such statistics, in the 1930s, were really tools to promote
Keynesian management. Since "prices" fell a lot in the 1930s, there
was "deflation" and thus the need for a monetary response. It was
just a roundabout argument for currency devaluation.
Another one that has fascinated
economists for centuries is the "balance of payments." This is
perhaps the strangest statistic of all to focus on, because it is
completely irrelevant. The "balance of payments" always balances,
without any government intervention. Have you noticed that, when
you buy something, the seller wants to get paid? Funny how that
is. And, even, if you didn't pay the seller, they would have
what amounts to a financial asset on their books, in the form of
an accounts receivable, thus balancing the "balance of payments."
The same jealous fear, with
regard to money, has also prevailed among several nations; and it
required both reason and experience to
convince any people, that these prohibitions serve to no other
purpose than to raise the exchange against them, and produce a
still greater
exportation.
These errors, one may say, are gross and
palpable: But there still prevails, even in nations well
acquainted with commerce, a strong
jealousy with regard to the balance of trade, and a fear, that all
their gold and silver may be leaving them. This seems to me,
almost in
every case, a groundless apprehension; and I should as soon dread,
that all our springs and rivers should be exhausted, as that money
should abandon a kingdom where there are people and industry. Let
us carefully preserve these latter advantages; and we need never
be
apprehensive of losing the former.
It is easy to observe, that all calculations
concerning the balance of trade are founded on very uncertain
facts and suppositions.
The custom-house books are allowed to be an insufficient ground of
reasoning; nor is the rate of exchange much better; unless we
consider
it with all nations, and know also the proportions of the several
sums remitted; which one may safely pronounce impossible. Every
man, who
has ever reasoned on this subject, has always proved his theory,
whatever it was, by facts and calculations, and by an enumeration
of
all the commodities sent to all foreign kingdoms. The writings of
Mr GEE struck the nation with an universal panic,
when they saw it plainly demonstrated, by a detail of
particulars, that the balance was against them for so considerable
a sum as must
leave them without a single shilling in five or six years. But
luckily, twenty years have since elapsed, with an expensive
foreign
war; yet is it commonly supposed, that money is still more
plentiful among us than in any former period.

Imagine, today, if there were no government statistics, not even the
most rudimentary ones such as GDP, the CPI, and the unemployment
rate. We would still know that the economy stinks. However, instead
of trying to jigger the economic statistics in various ways, to
produce an illusion of health where there is none, we might just try
fixing the problems instead.

Today, governments have simplified the process still further.
Instead of spending money and so forth to jigger the statistics,
they just jigger them directly. Today's CPI is widely thought to be
unrepresentative of current conditions. John Williams of Shadowstats
(shadowstats.com) has gone to great lengths to show what the
government's statistics would look like without the various
revisions of the past thirty years. Once you jigger the price
statistics, you also jigger the GDP statistics, since "real" GDP is
computed using price statistics. Unemployment statistics are also
jiggered, to remove people whose unemployment benefits expire and so
forth.
I think the SGS numbers themselves
are a bit exaggerated, but you get the idea. So, you could say
that although we have statistics today, they are so
fictionalized that we might as well have none at all. Their only
purpose is to obfuscate economic reality.
Another problem emerges when trying to use long-term statistics.
Any sort of GDP or CPI statistic from before 1920 or so is
basically a wild guess. Even worse, it is quite common for what
amounts to a commodity price index -- much like the Commodities
Research Board Continuous Commodity Index -- to be used as a
proxy for a "consumer price index." This seems to show huge
variation in the "CPI" prior to 1920, in other words, during the
gold standard era. This is wholly erroneous.
Hong Kong has been one of the greatest success stories of the
past half-century, without the use of statistics. They are of
use to historians, but not much good for policymakers.
