Like a pig
in mud, I love to root around in the data. A macro guy loves it when the BEA
releases another quarter’s worth of GDP.
Like a goat on top of a waste dump, you just never know what you will
find. So you just dig in.
And I did
just that. The data for the third quarter of 2014 was recently released and now
that the smoke has cleared, I thought I might spend a perfectly fine afternoon
seeing what I could see. And the results are pretty interesting. Have you heard
the term “unbalanced growth”? The US economy looks today like a teenager with a
pea-size head and arms that drag on the ground. We can only hope that things
equalize in the future!
I use the Q3 results to do some comparison
analysis. I could wait a few months to do this exercise but I could also wait to
bite into that super-hot slice of pizza too. So we could get a collective burnt
roof of our mouth here by focusing on the third quarter. But what I do here is
as kosher as a Wolfies hot corned beef sandwich on rye. So not to worry.
The first
thing I noticed is that the annualized value of real GDP reached $16.2 trillion
in 2014 Q3. Now that is a pile of stuff. Back in 1999 Q3 Real GDP was $12.1
trillion. So in those 15 years we increased national output by about a third. Even
if we compare today’s output to 2007 Q3 right before the recession started, we
are enjoying 7% more than 7 years ago.
7% more in
seven years is nothing to write home about but it does establish that even after
a major recession and an ensuing slow growth period, we are producing a large
amount of output today – considerably more than the outputs of the past. Again – I am not making a case that things
are wonderful in Macroland. But the most recent data establishes the fact that
we are producing more than ever.
That fact might
not be surprising but it gets a lot more fun when you bring out the Hookah. Err
I mean the rest of the data. As you probably know, real GDP has several major
components – based on the buyer – households, firms, governments, and the
foreign sector.
So let’s see
how these sectors contributed to the larger amount of production in the USA.
That is, who is responsible for buying about a third more when we compare 2014
to 1999? I summarize with the table below.
The table
has component shares of Real GDP. If the share of a category was 10% in 1999
and then 10% again in 2014 – that means that that buying by that group kept up
with GDP. The share did not change in those 15 years because it kept up. So in
the final column in the table – a POSITIVE SIGN means that category was growing
FASTER than Real GDP in those 15 years. A NEGATIVE SIGN means it grew SLOWER
than Real GDP.
What do we
see from the table? First, we definitely have unbalanced growth. Second, while
consumer good spending was a leading sector, the growth was coming mainly out
of durable consumer goods like autos. Spending on nondurable goods like food
and clothing did not keep up with RGDP as its share of spending fell. Third, while
the federal government purchased a larger share of the nation’s output, state
and local governments’ share fell by 2.7%. Finally and perhaps most
importantly, gross private domestic investment’s share fell from 18.5% to 16.8%
of GDP. Yes spending increased, but it grew considerably slower than real GDP
for the last 15 years. As you know this category is the key to future innovation
and productivity. While there was a marginal increase in the share of business
purchases of equipment, it was the structures part of investment that lagged.
Similarly on the retail side, residential housing’s share fell by 2.2% of Real
GDP. Finally while exports' share rose by 3.5%, imports share rose by 2.7% and
therefore net exports increased by only 0.7%.
Keep in mind
that Real GDP increased by about 33% in 15 years. But that amounted to an
average of less than 2% per year. All those categories in the table with a MINUS sign,
therefore, grew more slowly than 2% per year. The slow growth economy of the
last 15 years essentially was propelled by the Federal government (shares of
defense and non-defense increased by similar percentages ) and household spending
on durable goods and was held back by State and Local Government spending and
the construction of business and residential buildings.
One could
conclude the slow economic growth was caused by a highly unbalanced growth and
recovery. One could also conclude that whatever policies offered to promote
recovery have not worked. The Keynesian spending multiplier is premised on the
idea that while stimulus might be aimed at a single sector, the results would
spread across the economy. Such has not happened and it might help if
policymakers try to understand why.
