GDP and What We See
The United States is now said to be out of recession and to
have been out of recession for a good while because the government’s reported
gross domestic product has been increasing. Yet polls show that a large
percentage of the population believes the country in still in a recession. An unusually
high levels of unemployment and underemployment, a lower average net worth of
households, a depressed market for residential real estate, and other factors support that opinion and
indicate that the economy is still doing poorly.
Various writers have pointed out the shortcomings of GDP
statistics as an indicator of the health of the economy. There are significant problems
with both the collection of the data and the methods of analysis. Additionally
activity in the so-called underground economy of both illicit activities and
otherwise legal but unreported cash transactions is not measured. Neither is activity
in the fully legal and probably much
larger second underground economy of goods and services produced by people for
themselves with no money changing hands – everything from home gardening and
canning to do it yourself-ers painting their houses to friends helping each
other with car repairs and household
wiring. Also GDP calculations treat all types
of measured economic activity as equivalent.
A given amount of money spent on a Solyndra or a Cool Hand Luke stimulus
project of activity no more productive than digging holes and filling them back
up counts exactly as much as the same amount spent on developing the next
iPhone.
In ordinary times these and other difficulties do not
prevent the GDP statistics from being useful in estimating the health of the
economy. People can assume that the omissions, problems of method, and
systematic errors will have about the same effect as a percentage of the whole
at one time as another and use the trends in the GDP as indicators of a
growing, stagnant, or declining economy. However that is acceptable only so
long as the assumption is valid. If the
percentage of economic activity that is either unreported or unproductive changes
significantly, the GDP statistics will give a false reading on the health of
the economy. This happened immediately
after World War II when the official GDP registered a serious decline because
of a decrease in government spending on the war, but the real economy saw neither
a depression nor serious unemployment but rather an improvement in the average
standard of living. The earlier war time GDP was artificially high
relative to the actual health of the domestic economy because so much of that
GDP was spending on the war – spending which, while necessary, did not produce as
much as the numbers alone would have indicated in the way of goods and services
for the domestic economy. We have had something similar in reverse order in the
last few years. The post-2008 GDP statistics are artificially high relative to
the actual health of the domestic economy because an abnormally high percentage
of the GDP has been unproductive and/or inefficient government spending which
has produced comparatively less in the way of useful and desirable goods and
services in the real economy. The country is thus doing worse than the GDP
numbers indicate, and citizens may indeed believe their lying eyes rather than
what the politicians are telling them.
