EPSTEIN'S GREAT AMERICAN SAVINGS (SIC) MYTH

In the cover article of
the May 28 edition of Barron’s (see
The
Great American Savings Myth) Gene Epstein, Barron’s economics
editor, argues that household saving is being underestimated.
Epstein’s argument centers principally on two issues – the growth in
household net worth and the absence of spending on intangibles, such as
research and development, from our official Gross Domestic Product
(GDP)/saving statistics. I offer a counterargument that increases in
household net worth do not necessarily represent saving in an economic
sense. I also present evidence showing that investment in human capital
– higher education and research/development – has not shown any
extraordinary growth since the official measures of household saving
have been plummeting in recent years. If households are so wealthy, why
have they recently been on a borrowing spree? If the return on business
capital is so great, why have businesses been buying back record amounts
of their equities rather than using their profits to spend more on
physical and intellectual capital?
Firstly,
let’s discuss the concept of saving in an economic sense. Saving
refers to spending your income (production) on things that will enable
your income (production) to rise the future. This might involve spending
on education that will enable you to earn a higher income in the future.
This might involve purchasing newly issued corporate stocks and bonds,
the proceeds of which are used by the corporation to purchase capital
equipment or spend on research and development. In other words, saving
involves spending present income on things that hold the prospect of producing future
income. For the economy as a whole, saving means directing land, labor
and capital (both human and tangible) toward the current
production of goods and services that will enable additional future production. Savings
are the accumulation of past saving.
There
are two ways that households can increase their net worth – net worth
being the difference between the market value of their assets and the
value of their liabilities. One way households can increase their net
worth is to spend part of their current income on the acquisition of
additional assets – stocks, bonds, deposits, houses and consumer
durable goods. The other way households can raise their net worth is for
the value of their previously acquired assets to rise, that is, capital
appreciation.
In
the postwar era, capital appreciation has been the dominant factor
contributing to changes in household net worth. From 1952 through 2006,
the median contribution to the change in net worth from capital
appreciation has been 67%. But, as shown in Chart 1, in 11 of the past
12 years, the contribution from capital appreciation has been greater
than the 67% median. In 2000, capital appreciation’s contribution to
the change in household net worth was right at the median. So, the sharp
increases in household net worth that started in 1995 were not
due to household saving in the economic sense.

Now,
does the increase in the price of an asset necessarily mean that the real
output produced by that asset is growing apace with the nominal price of
that asset? For example, in recent years there has been a rapid
appreciation in the nominal value of residential real estate. Has the
real value of housing services
produced by the existing and new houses kept pace with the nominal
increase in the value of owner-occupied real estate? No. Chart 2 shows
that the real implicit rent on owner-occupied housing has been falling
relative to the nominal market value of owner-occupied housing since the
mid-1960s and the rate of that decline accelerated in recent years as
the house-price appreciation took off. This is true not only for
owner-occupied real estate but for all household assets. Chart 3 shows
that real GDP as a percent of the nominal market value of household
assets has been steadily falling for years. This
just demonstrates that the appreciation in the prices of assets does not
mean that all of that appreciation represents increases in real economic
wealth. If it did, then the residents of Zimbabwe would be
experiencing very rapid increases in their real wealth (see the Ludwig
von Mises Institute’s Zimbabwe:
Best Performing Stock Market in 2007?).

One
factor that determines the wealth of an economy is how fast its real
capital stock is growing. After all, its capital stock plays an
important role in the production of future goods and services. Chart 4
shows the year-over-year percent change in the per capita U.S. capital
stock, which includes private sector fixed assets, government sector
fixed assets and consumer durable goods (motor vehicles, washing
machines, etc.). The median annual percent increase in the U.S. per
capita real capital stock from 1953 through 2005 was 1.88%. In all but
three years from 1990 through 2005, the growth in the U.S. per capita
real capital stock has been below
the median. In those three years in which the capital stock growth was
above the median – 1998, 1999 and 2000 – that growth was not
extraordinary especially compared with that of second half of the 1960s.

Not
only has the growth in the U.S. real capital stock been slower in recent
years, but the composition of that growth has shifted radically toward
household-related capital stock vs. business-related. Chart 5 shows that
the net capital stock of combined consumer durable goods and private
residential dwellings started rising rapidly in 2000 relative to the net
capital stock of the businesses. In 2005, the combined real household
capital stock was a record high 143.4% of the real capital stock of
businesses. Are 5,000-square-foot houses with flat screen televisions
hanging on the walls and three SUVs with leather seats in the
three-truck garages likely to enable the U.S. economy to produce more
goods and services in the future than businesses’ fixed investments in
plant, equipment and software?

The
nature of the U.S. economy has changed in recent decades. We are less
and less metal benders and more and more idea benders. That is, the U.S.
economy is becoming more knowledge-based as developing economies take on
lower value-added manufacturing activity. So, perhaps looking at the
growth or composition of U.S. tangible
capital is less appropriate today. It might be better to look at
measures related to human capital such as expenditures on research/development and
higher education. Chart 6 shows the year-over-year growth in real
higher-education expenditures and real research and development
expenditures. (Real research and development expenditures were
calculated by deflating nominal expenditures by the chain price index
for higher education expenditures.) Since official measures of household
saving have been plummeting, there has been no extraordinary pick up in
investment in human capital.

Epstein
and other dissaving deniers argue that the official household saving
data are biased downward because they subtract things from income and
don’t include other things in income. In the Federal Reserve’s
flow-of-funds data there is a series called “household net financial
investment” that allows us to get at the heart of the saving issue.
Net financial investment is the difference between households’ net
acquisition of financial assets – stocks, bonds, deposits, mutual
funds, claims on pension and insurance reserves – and the net increase
in their liabilities. How does one acquire financial assets? By spending
less on goods, services and tangible assets than one’s income and by
borrowing funds to purchase financial assets. Let’s put this in
equation form:
(1)
Net Acquisition of Financial Assets = Income – Spending
+ Borrowing
Now,
let’s re-arrange some terms:
(2)
Income – Spending = Net Acquisition of Financial Assets
– Borrowing
From
Equation (2), we can see that if borrowing is greater than the net
acquisition of financial assets, that is, the right-hand side of
Equation (2) is negative, then the left-hand side of Equation (2) must
be negative, also. So, if our borrowing exceeds our net acquisition of
financial assets, then we are spending more on goods, services and
tangible assets than we are earning (producing). Some might dare call
this dissaving.
Let’s
take a look at households’ net acquisition of financial assets and
their net increase in liabilities. Chart 7 shows that starting in 1999,
households’ net increase in liabilities has exceeded their net
acquisition of financial assets. From 1952 through 1998, households
spent less on goods, services and tangible assets than they produced.
But suddenly in 1999 through 2006, households started spending more than
they produced.

The
difference between the two series in Chart 7 – net financial
investment – is shown as a percent of personal income (before taxes)
in Chart 8 along with the official measure of household saving, which
uses after-tax income. The magnitudes of the two series are different,
but the story is the same – U.S. households are spending more on
goods, services and tangible assets than they currently are producing.

To
paraphrase my dear mother, may she rest in peace, if we American
households are so rich, why are we borrowing so much? Chart 9 shows that
the net increase in household liabilities as a percent of personal
income hit a postwar high in 2004 and remains above that of any year
prior to 2002. Epstein and others talk so much about household net
worth, but they never mention household leverage. Chart 10 shows that
total household liabilities are at a postwar high compared to the market
value of total household assets – tangible and financial. This implies
that household debt has been growing faster than the market value of
household assets at a time when we have seen extraordinary increases in
the market value of household assets (see Chart 11).

If
households are intent on spending their holding gains on assets, it is
not surprising that household borrowing has shot up. If I sell an
inflated asset in order to fund additional spending, the buyer either
has to cut back on his spending or borrow to fund the purchase of my
asset. If the buyer cuts back on his spending, then, on net, total
spending does not increase with the sale of my asset. If the buyer
borrows in order to purchase my asset, then net spending increases, but
so, too, does net borrowing. Alternatively, I could retain the asset,
but use it as collateral for increased borrowing. This is exactly what
thousands of “homeowners” have done in recent years.
Epstein
argues that corporations are boosting the value of their shares, and
thus, household net worth, by investing in tangible and intangible
assets. Is it through investing in their businesses that corporations
have been boosting shareholder value in recent years or rather by
“investing” in their own shares? It would seem the latter. Chart 13
shows the annual net issuance of equities by U.S. corporations in
relation to their profits. In 2006, in absolute as well as relative
terms a record amount of corporate equities were “retired.”
Corporations have been increasing households’ net worth not so much by investing record profits in their businesses, but by
using those profits to buy back their own shares. And now that profit
growth is slowing, corporations have stepped up their borrowing to fund
share buybacks, just as they did in the stock market bubble of the late
1990s (see Chart 14). Households
have been “investing” the proceeds of these stock buybacks in
McMansions and SUVs. Is this a combination destined to increase the
future productive capacity of America?

Gene
Epstein claims to have an affinity for Austrian economics. In fact, he
delivered the Hazlitt lecture at the 2000 Austrian Scholars Conference
sponsored by the Ludwig von Mises Institute. After reading Epstein’s
latest Barron’s article, I
can only imagine that Ludwig is spinning in his grave!
