Why does government data need to be revised so often? Is it conspiracy, as
some claim, or is it methodology? And if it is methodology that leads to faulty
data, then why not change the methodology? Is unemployment a lagging indicator,
as conventional wisdom suggests? We look again at the underlying assumptions
to suggest that things are not always the same. And finally, we look at unsustainable
trends, fiscal deficits, and health care -- there is a connection.
But first, a quick note about the latest "Conversations with John Mauldin" that
I just did with Don Coxe and Gary Shilling. These two esteemed analysts have
different views on whether commodity prices will rise or fall, and are not
afraid to make their views known. I edited the final transcript today, and
I can tell you that even though I was "at the table" I learned a lot reading
it the second time. If you want to understand the nature of what is a very
central debate, this is a must-read. This was a VERY lively debate. Most of
my friends know that I am not shy, but it was hard to get a word in edgewise
as these guys went at it. It was great fun to watch.
And if you have not yet subscribed, you can go back and listen to my Conversation
with Chris Whalen and Rick Lashley on the banking crisis, and see if you can
figure out what motivated the Manhattan district attorney's office to call
me asking for clarification. Plus the quintessential piece with Lacy Hunt and
Ed Easterling on the fundamentals of the current economic crisis, which many
subscribers said was worth the price of an annual subscription. And then there
is the Conversation I did with Nouriel Roubini. It is all there for you.
The new Conversation will be posted early next week. Subscribers will get
an email notifying you when it is up. Also, George Friedman of Stratfor and
I are going to start doing a regular quarterly Conversation that will be a
separate product, but if you subscribe today you will get it as part of the
regular service for a year.
Right now, we are offering a subscription for $109, $90 off the regular $199
price. To learn more, you can click
here and subscribe, if you haven't already. Insert code JM77 for this
special offer. You can enter that code on the final screen of the subscription
process.
Note: When George and I record that first piece sometime in
the next few weeks, the price will rise to $129 a year, so you should act
now. As we add more features like the one with George, current subscribers
will simply get the new services, but the price for a new subscription will
rise. New subscribers will however get access to the previous Conversations,
at least for now.
Can I Have Some More of that Data, Please?
One of my regular reads is the blog The Big Picture. They featured
a short piece by Michael Panzner this week. He put together some rather interesting
data and then asked a question, which gives me an opportunity for discussing
government data. Let's see what he had to say, and then I will make my comments.
"Many market-watchers claim that U.S. economic statistics are increasingly
being revised downward in subsequent periods, suggesting that the figures initially
being reported by Washington are "puffed up," so to speak, most likely for
political purposes.
"Well, I went back and had a look at the differences between the reported
and revised data for various series, including monthly retail sales, nonfarm
payrolls, industrial production, and durable goods orders, to try and figure
out if the cynics are right.
"Using data from Bloomberg, I calculated whether the revised data for each
month was lower than the first-cut estimate. Then I tabulated 12-month running
totals for each series to see if there has been some sort of systematic bias
(in other words, whether the pattern of monthly downward revisions was trending
higher instead of undulating up and down).
"To make the comparisons easier, I subtracted the 12-month tally as of May
2002 (an arbitrarily chosen date) from the monthly totals for all four economic
series so that the starting point for each would be the same - zero.
"Based on a quick read of a graph of the data (see below), it does seem as
though the pattern of negative revisions has been trending higher lately, especially
during the past year or so, suggesting that the cynics may be on to something.

"That said, I am not a statistician, and the results may be nothing more than "noise." There
is also the possibility that my methodology is lacking (because, for example,
the margins-of-error for each month's data are relatively large, or because
of certain quirks that crop up when an economy is in transition). Still, you
gotta wonder..."
Actually, Mike (can I call you Mike?) your last thought is the correct one: "or
because of certain quirks that crop up when an economy is in transition."
Go back to 2003-04. Notice that the numbers of downward revisions in non-farm
payrolls are negative in your graph? Remember all the talk back then about
the "jobless recovery"? We can now look back and see there were a lot of jobs
being created. They just did not show up in the early statistics. And look
at the opposite reaction in industrial production: here they revised strongly
downward for a the better part of two years, yet it turned out there was a
production boom going on.
Was all this a conspiracy on the part of the Bush administration to make things
look worse than they actually were? Hardly seems like rational political behavior.
The "problem" comes from the methodology. There is no exact data for any of
those statistics. They have to get as much data as they can and then make estimates.
Part of the process of estimation uses previous trends. It is as if we were
using past performance of a mutual fund or stock to project future returns.
Even though we look at the past performance, we should know that past performance
is not indicative of future results. Just look at some of the top-performing
value-oriented mutual funds in the recent bear market, like superstar Bill
Miller's Legg Mason Value Trust fund (LMVTX), the after-fee returns of which
had beaten the S&P 500 index for 15 consecutive years, from 1991 through
2005. It did rather poorly last year, even in comparison with the S&P,
which was horrid. Past performance is interesting, but it can disappoint. And
sometimes rather viciously.
Now, just as saying that a fund on average will produce a 10% return does
not mean that it will yield 10% every year, neither do government statistics
work that way. While the methodology for each series of data is different,
they all are more or less trend-following. They take past relationships in
the data they can gather and use them to estimate current numbers. And -- this
is important -- on average and over longer periods of time, they are pretty
accurate.
They will revise the data many times over the coming years, getting closer
and closer to the actual numbers. For instance, I can't remember exactly when,
but it was several years later that we learned that we were already in a recession
in the third quarter of 2000, at the very time most economists were calling
for a robust economic future! (Except for your humble analyst, who was predicting
a recession, and had been for some time because of the inverted yield curve,
but that's another story.)
But in the short run, at economic transitions they are going to get it wrong,
because the backward-looking data is mean-reverting. But how else would you
do it? One of the keys to economic transitions is to look at the direction
of the revisions. Recently, the revisions have all been negative. Things are
actually getting worse than the initial data suggested. And during the last
recovery the data kept getting revised upward, especially six months and one
year later.
The Fault, Dear Brutus, is Not in Our Stars
Look again at the very useful chart above (great work, wish I had thought
of it!). Non-farm payrolls, which for some odd reason everyone pays attention
to, is especially wrong at the turns. Anyone trading on non-farm payroll data
deserves the losses they will get.
One of the reasons that non-farm payrolls are so often revised is that the
Bureau of Labor Statistics (BLS) is forced to estimate the number of new businesses
being created each month that are simply under the radar screen of government
statisticians. This number is called the birth/death ratio. You could not create
a useful payroll number without this estimate, yet it is simply a wild-eyed
guess based on past trends, which by definition we know will change at economic
turning points.
Further, almost no one pays attention to the fine print in the data, which
talks about margin of error. The statisticians clearly understand the limits
of their data, even if the public does not. Often, the margin of error is larger
than the number being given, so that a positive number may actually turn out
to be negative, and vice versa, when viewed from a few years out.
As Cassius said in Julius Caesar, "The fault, dear Brutus, is not in
our stars, But in ourselves, that we are underlings."
Faith-Based Economics
Should we cast aspersions on the data creators? I rather think not. The various
government statistics creators are doing their best to give us information
that, over time, will be useful. Some is more useful than others in real time.
Some has large time lags before it is accurate. To expect the BLS or the Commerce
Department to have accurate current data is expecting them to know the future.
The very people who are the most critical would never presume to be accurate
about the prices of stocks six months out (or even one month), on a consistent
basis. Yet that is the kind of prescience they want from government statisticians.
Do you really want data from government sources that makes assumptions about
economic recoveries and recessions? That is the job of independent economists,
and they generally do it pretty badly. There is no need for the government
to compound the errors.
Again, repeating myself, anyone who trades on government statistics as being
anywhere close to accurate in real time deserves any losses they get. They
are at best a foggy window through which we peer into the future. Taken together,
and with some seasoning of time, they can be rather useful; but to pin hopes
of a recovery or a bull-market run on one week's data is hazardous to one's
wealth.
Reading and watching all the analysts and economists who "see" recovery in
one set of data or another makes me wonder what sort of faith-based economics
they actually practice. Just as it requires faith to believe in God, it also
requires a lot of faith to believe in forecasts made on a single month's set
of data, or based on past performance.
Are you interested in finding a real green shoot? Let's look for a quarter
when the economic data keeps getting revised upward, two and three months out.
That will signal a real recovery. As long as the data is being revised downward,
the economy is "having issues," as my kids would say.
Quick sidebar to those who keep asking: Yes, I think we have seen the worst
of the economic data, as far as GDP goes. But that does not mean we don't have
further negative quarters in our future. I just don't think they will be a
negative 6 like they have been the last two quarters. And we may even see a
quarter this year with a positive number. But take it with a grain of salt
when the usual suspects declare the end of the recession. Look into the data
that produces the numbers. As Gary Shilling points out, eight of the last eleven
recessions have had a positive quarter, only to see more negative quarters
follow. GDP numbers are quirky. But here's to hoping for a real recovery when
we do see the next positive number.
Is Unemployment a Lagging or a Leading Indicator?
There is a very interesting animated graphic done by Chris Wilson at Slate.com
(http://www.slate.com/id/2216238/).
It shows the progression of unemployment by US county over the last two years.
I reproduce the beginning and ending stages of the graph for you below, and
apologize to those of you who are reading this in black and white, as it will
not be as dramatic. But if you watch the entire series, it shows how rapid
the deterioration in unemployment has been. (It takes about ten seconds.) The
first graph shows that there 2.6 million jobs had been created in 2006. The
last one shows that job losses were 5 million through March and, if we add
in April and estimates for May, it will be close to 6 million. Again, the actual
animation is dramatic, and made my daughter go "Ouch!"


It's been 50 years since we have seen unemployment drop as rapidly as it has
in the current recession. Given that we have a much smaller percentage of manufacturing
jobs now, that volatility is breathtaking. Look at the data since 1930 from
the St. Louis Fed:

The typical pundit keeps telling us unemployment is a lagging indicator, and
that the recovery will be well under way before it shows up in the job numbers.
Therefore, you should buy what they are selling, because the recovery is on
its way. But that may not be the case this time. One of my favorite reads,
when I get to see it, is the economic analysis from Bridgewater. They are among
the best thinkers anywhere, and everyone who follows them gives them a great
deal of credence. This is what they wrote about unemployment being a lagging
indicator last month:
"Normally, labor markets lag the economy because incremental spending transactions
are financed via debt, stimulated by interest rate cuts. But as long as credit
remains frozen, spending will require income, and income comes from jobs. And
debt service payments are made out of income. Therefore, in a deleveraging
environment job growth becomes an important leading, causal indicator
of demand and other economic conditions.
"... The bounce in the economy and the stabilization in markets reflect government
actions that are big enough to impact near-term growth rates, but are not sufficiently
directed at the root problem of excessive indebtedness to produce permanent
healing. The deterioration in employment markets will continue because companies'
profit margins are so deeply damaged that a little bounce in growth won't do
much to alter their need to cut costs. This deterioration in labor markets
will undermine demand and continue to pressure loan losses, which will keep
the pressure on the banks and elevate the cost of capital for tentative borrowers,
inhibiting credit expansion."
This again illustrates the problem of using past performance to project future
results. You have to look at the underlying conditions in order to get a real
comparison, and we have not seen a deleveraging recession in the US for 80
years. Using the past data in today's world is statistical masturbation: it
may make you feel good, but it is not producing anything really useful, and
may be harmful to your portfolio.
An Unsustainable Trend in Debt
This week, the federal government published two important reports on long-term
budgetary trends. They both show that we are on an unsustainable path that
will almost certainly result in massively higher taxes. By 2016 we will have
to fund Social Security out of general revenues, as the surplus we now have
will be gone. And there are no trust funds. They are a myth. It as if I wrote
myself a check for $2 trillion and then declared I was worth $2 trillion. The
money is just not there. Social Security makes Bernie Madoff look like a small-time
crook.
And Medicare is in far worse shape. For those with the stomach, you can read
Bruce Bartlett's analysis at http://www.forbes.com/2009/05/14/taxes-social-security-opinions-columnists-medicare.html.
He estimates that taxes will have to go up by 81% if we are to pay the obligations
as they now stand.
Now that is unsustainable. It won't happen. And as the saying goes, if something
is unsustainable, at some point it will stop. No getting around it. Long before
we get there, change you will not like will be forced on the US.
The following headline caught my eye: "Obama Says US Long-Term Debt Load is
'Unsustainable.'" Yet they announced a $1.8 trillion deficit, which is really
going to be at least $2 trillion, and are getting ready to pass health-care
programs that will mean at least a trillion in deficits for as long as one
can project.
How will they pay for it? Even getting rid of the Bush tax cuts will only
produce a few hundred billion a year, which is nowhere near enough. They project
much lower medical costs in the future, because they assume they are going
to figure out ways to cut costs and make medical care more efficient. As if
no one has ever tried that.
Yes, there are some savings on the margin; but the only way you really cut
costs is to ration health care, especially health care in the last year of
life, which is about 30% of health-care expenses. That is going to be very
tough in the US. But when faced with a real budget crisis, the choices are
going to be stark. And that crisis is coming if we do not control spending.
You cannot propose massive increases in spending without either creating crushing
debt that the markets will simply not allow, pushing interest rates much higher
and really slowing growth and hurting the economy. It is a simple fact that
you cannot increase the debt-to-GDP ratio without limit.
We found the limit on personal and corporate debt this past year. We pushed
the limits until the system crashed. And now the US government wants to basically
do the same thing. They are planning to see where the limits on government
debt-to-GDP will be. Unless cooler and more rational heads in the Democratic
Party prevail, this is not going to be pretty. Sometime in the middle of the
next decade we will hit the wall, and it will make the current crisis pale
in comparison.
The only way to solve the problem is to grow GDP more rapidly than debt, and
for that to happen you have to have policies which are shaped for the growth
of the economy or massive savings by consumers. And right now we have neither.
Cap and trade is hugely anti-growth. So are high corporate taxes, and Obama
is proposing to effectively raise corporate taxes by closing loopholes for
income earned outside the US. Much better would be to lower the overall corporate
level to a competitive world rate and then require the offshore income to be
taxed. A lower rate would actually increase tax revenues.
Looming protectionism worldwide is a problem. (See the article at http://www.msnbc.msn.com/id/30758018.)
Towns in Ontario, Canada with a population totalling 500,000 have effectively
barred US contractors from doing business with them, in retaliation for job
losses stemming from US protectionism in the stimulus plan. That movement is
spreading. A US steel mill with 600 union jobs will have to close down because
its owners are not US-based, and thus it is not technically a US supplier.
They are losing jobs to US-owned mills -- but those are US jobs. The insanity
goes on and on. As I have written for many years, the one thing that really
gets me worried is protectionism. That can make this very significant recession
into a depression quicker than you can imagine. Bad ideas have bad consequences.
All in all, we face some very difficult decisions, not just in the US but
all over the developed world. Ironically, the less developed nations will have
fewer problems and on a relative basis will likely grow much faster than the
developed world. But, multi-trillion-dollar deficits and massive new programs
are not the right answer.
Obama is right: the debt load is unsustainable. Let's hope he will do more
than talk, and show some budget restraint.
Woody Brock has given me permission to pass on to you his recent notes on
this very topic of what we have to do to get out of this crisis. It will soon
be an Outside the Box. Read it. It is a very sobering and thought-provoking
piece.
Some Thoughts on the Health Care Problem
Now, some positive news. This week I visited the Cleveland Clinic and went
through their Executive Health Program (more on that below). I got to visit
for several hours with my doctor, Michael Roizen, of YOU: The Owner's Manual fame
(not to mention all his subsequent books). They have now sold over 20 million
copies, and I highly recommend them.
I have long been a student of medical trends, and long-time readers know that
I think the next really big boom will be in the biotech world. I asked Mike
what three things he thought would have the biggest impact in the next five
years in medicine. What he said gave me hope, because he thinks there may be
some advances in medicine that could help solve some of the basic health issues
we all face, and at the same time give us some relief from the high and rising
costs of medical care. I was aware of most of the research, but did not know
that we were as close as it appears we actually are.
Briefly, he feels there are three developments in late-stage trials that could
have major impacts. The first is the development of sirtuin, which so far seems
to be delaying the effects of diabetes but also seems to work for a host of
diseases that are inflammatory in nature (including many heart-related issues).
It essentially delays the symptoms for 30-40 years. While the current trials
are for very specific diseases, he thinks sirtuin will have a wide applicability
and that it could be huge, as inflammation is the cause of a number of diseases.
This could prolong useful life and forestall a number of debilitating conditions.
Second, there is a late-stage-three trial due out soon that promises to increase
muscle mass. I have been reading about such developments, but was not aware
that something might be available within a few years. This promises to help
people stay active a lot longer than currently possible, which will be a good
thing if we are going to live longer.
And finally, there is a study and trial which shows that DHA may delay the
onset of Alzheimer's disease, which eats up a significant portion of US medical
budgets.
I recently spent time with a research doctor at the University of California
Irvine who believes that muscular dystrophy and other brain/nerve-related diseases
may be conquered within five years.
We may just get lucky. Instead of high and rising medical expenses that we
cannot pay for without bankrupting the country, we may be able to reduce our
medical bill by staying healthier and living longer.
Everybody should be like my personal hero, Richard Russell. I hope to be writing
as well as he does when I am 85. With some luck, I might just make it.
Let me quickly recommend to my readers that they get serious annual physicals.
At the Cleveland Clinic this week I saw seven doctors in one and a half days,
and went through some serious poking and prodding. The program was tailored
to my needs, as it is different for every person. You see professionals who
are geared to your physical challenges. They make all the arrangements, and
a staff person walks you into see the doctors, who are on very tight schedules.
The advantage of the Cleveland Clinic is that they are very oriented toward
helping you not get sick in the first place. I am turning 60 this year, and
Iwant to be active for a very long time. You have to be proactive.
As an aside, I had a colonoscopy. I was really dreading it, but it is one
of those things you need to do. As it turns out, it was nowhere near as bad
as I thought, and they basically gave me a drug which allowed me to relax and
only experience a little discomfort. ("You are going to feel really relaxed
in about 30 seconds.")
You can learn more at www.clevelandclinic.org/executivehealth.
Whether it is there or somewhere else, get a serious physical. I want you to
be reading me in 25 years as much as I want to be writing.
It is time to hit the send button. I will close by wishing you a very healthy
week.
Your really an optimist at heart analyst,
