The conclusion of my previous post was that financial corporate business
(FCB) is less than 40% as productive as nonfinancial corporate business
(NCB). That conclusion, however, rests on the assumption that everything counted in Gross Value Added (GVA) is output.
The assumption is not well-founded. Dirk Bezemer and Michael Hudson, in Finance is Not the Economy, wrote
National
accounts have been recast since the 1980s to present the financial and
real estate sectors as “productive” (Christophers 2011).
The
calculation of GVA has been "recast": It has been changed in ways that increase what counts as
output. The more the output, the more productive a business is -- or
the more productive it is reported to be, depending on whether the new
inclusions are output in fact, or only in the calculation.
As for
myself, I like to say "nonfinancial" businesses are the ones that
produce the goods and services we buy, and "financial" businesses
are the ones that produce the money we use to buy those goods and
services. That's a bit of a simplification, but it provides clarity. It also invokes the image of
financial business as entirely non-productive.
I have not
concluded that financial business is entirely non-productive. Nor have
I concluded that it isn't. Thus I asked the question in the title of
the previous post: How productive is finance? But my answer depends on
the size of output as given by the GVA of finance. If the output of
finance has been increased by changing what's counted to make output
look bigger, then GVA overstates the output of finance, and my previous
post overstates the productivity of finance.
The Recasting
It seems Bezemer and Hudson's "recast since the 1980s" remark is a simplified version of the story. In Financial Output as Economic Input: Resolving the Inconsistent Treatment of Financial Services in the National Accounts, Jacob Assa provides a brief history of the changes to the accounting of finance in the System of National Accounts (SNA):
At
a first stage in the history of this question (SNA 53 and before), all
financial intermediation activities were excluded from calculations of
national output based on the value-added approach, since they were
considered to be mere transfers of funds (similar to social security
payments) and hence unproductive. An intermediate approach followed with
the SNA 68, where the output of the financial sector was considered to
be an input to a notional (i.e. imaginary) industry which has no
output....
Finally, with the 1993 SNA, financial intermediation
became an explicitly productive activity, for which value added is
imputed based on the net interest received by financial institutions
(the FISIM approach).
Assa points out that these additions to the GVA of finance are subtracted
from other components of GVA: They are treated as costs to the industries using those financial
services, "thus affecting only the relative size of the financial
sector rather than the total GDP".
So, if I have it right,
they are not using these accounting revisions to double-count finance
and boost the reported size of GDP. But they do count financial costs as
part of output, by including them in the Gross Value Added of finance. In this
context, it is important to remember that with "SNA 53 and before ...
all financial intermediation activities were excluded ... since they
were considered to be ... unproductive."
The end result of this
"recasting" of the national accounts has been to include more financial
cost as financial industry output and to count it as part of the Gross
Value Added of finance.
The Bezemer and Hudson article and the Jacob Assa paper both reference Brett Christophers's 2011 paper Making finance productive. In the Abstract of that paper, Christophers writes:
By
placing different activities on different sides of a pivotal
‘production boundary’, national income statisticians effectively dictate
what counts as productive – as adding value to the economy – and what
does not.
His statement clearly describes the
redistricting of data that increased the output attributed to financial
business. In brief, then, Bezemer and Hudson were exactly on point: the
national accounts have been "recast" to present finance as productive.
Calling
something productive doesn't mean it is productive. Sure, we may be
able to buy more cars because of finance. And we may be able to
manufacture more cars because of finance. But finance didn't make the
cars. It only made the money available.
It made the money available, and sent us the bill. And yes, that may be fair. But "fair"
is not the same as "productive".
How much output does
finance create, really? Not much; this is clear from the graphs of the
previous post. But those graphs use the "recast" Gross Value Added as
the measure of financial output. The true measure of financial output is
less than the graphs show. And that means the productivity of finance
is less than those graphs show.
How much output does finance create, really?
Michael Sandel teaches political philosophy at Harvard University. In an interview with Sam Harris of Making Sense, Sandel said
It's been estimated by folks who know more about it than I do, that only
about 15% of financial activity consists in investment in new
productive assets for the economy. 85% consists of simply bidding up the
price or betting on the future prices of already existing assets or,
increasingly, synthetically created derivatives and other fancy
financial instruments that have precious little to do with making the
economy more productive.
The productivity of finance is about fifteen percent.
In an article at LinkedIn, Rana Foroohar wrote
Market capitalism, as envisioned by Adam Smith, was supposed to funnel
our collective savings into productive investment, via the banking
system. But today, deep academic research shows that only around 15% of
the money flowing from financial institutions actually makes its way
into business investment. The rest gets moved around a closed financial
loop, via the buying and selling of existing assets, like real estate,
stocks, and bonds.
The productivity of finance is about fifteen percent.
Sandel
and Foroohar agree on the number. Neither one documents it: no
references, no links, no quotes, no sources, not even any detail. So I
cannot accept the number. Sure, it's probably right, I will say that. But
as presented, it is no better than a rumor.
But how much output does finance create, really?
The productivity calc is one thing, the GVA calc another
Using
my calculation, GVA per dollar of profit as a measure of industry
productivity, corporate finance is less than 40% as productive as the
standard set by nonfinancial corporate business. On average, 37.9%. But
if GVA overstates the output of finance, then 37.9% overstates the
productivity of finance.
I'm not the guy who can determine what is
and what isn't financial output. Mine is only a hobbyist's eye. To my
eye, finance produces no output, only cost. I could guess that finance
is only half as productive as the "Gross Value Added" says. I think it must be much less than half, but I certainly don't know. So to be fair (yeah, that
again) fifty-fifty is the only guess I can make.
If half the
GVA of finance can legitimately be considered output, then, on average,
half of our 37.9% number is the answer. That brings the productivity of
finance down below 20%, meaning finance is less than 20% as productive
as nonfinancial business, per dollar of profit. More accurately, less
than 19%.
That is not far at all from the 15% number of Sandel and Foroohar.
But
then, again, if "output per dollar of profit" is a valid way to figure
the productivity of industry, and if it was not used in figuring the 15%
number, then we should want to use it and apply the "less than 40%"
rule, reducing the 15% to less than six percent.
And if we are
now saying that finance reaches less than 6 percent of the productivity
achieved by nonfinancial corporate business, well, we are almost back
down to zero. Nonfinancial businesses are the ones that
produce the goods and services we buy, and financial businesses
are the ones that produce the money we use to buy those goods and
services. The narrative is clear: Finance is entirely nonproductive.
