Statistics: Scientific Consensus on Climate Change?

Email this post Print this post
By Barry Ritholtz - December 31st, 2009, 3:30PM

One of the memes I’ve heard recently in the climate debate is that there is no scientific consensus — that there is actually strong disagreement.

The main basis of this argument is that 31,486 dissenting scientists have signed a petition against the belief that Global Warming is man made at the PetitionProject.org.

I don’t want to debate climate change; rather, I want to look at that argument to see if there are any statistical flaws in it.

My problem is whenever anyone uses a single, out of context, data point. What does this number actually mean? Is 31,486 alot or a little? How many scientists are there in the US? etc.

I heard this argument the other day, and went hunting down a visual way to express it, and found this via Information is Beautiful:

This does not resolve the debate — there are more variations (Climate Change: A Consensus Among Scientists?) — at but it demonstrates an obvious flaw in the “dissenting scientist” argument.

Here is the breakdown of skeptics, by field:

Visuwords is is a visualization tool based upon Princeton University’s WordNet.

The online graphical database — part dictionary, part thesaurus — that groups words by their meanings and associations with other words and concepts. These related linguistic ideas are visually displayed in an interactive graphic.

The most interesting visual displays come from the broadest topical words. Try words like Music, Biology, War; I’ve had more luck with nouns than verbs.

Each node can be further opened, revealing related ideas, words, etc. As an example, here is what “Economics” looks like:

We won’t get the final numbers til after the close today, but here is what they look like going into the final session:

• Nasdaq is up 45%; Its the big winner for 2009 of the major US Indices;

• S&P 500 index up 25% for the year.

• Dow Jones Industrial Average is up 20% for the year (up 61% from its March lows); Transports are up 18%.

Here is how the year looked, month by month, along with major events:

Today also marks the end of the decade as well as the year.

Below you will see a chart depicting the price performance of the Dow for each decade since 1900. As you can see, from the close of 1999 through 2009 was the second worst performance on record. Only the Great Depression decade of the 1930s was worse.

The current zeros decade also shares an unfortunate outcome with the 1930s in being a decade during which the Dow actually ended lower than where it started.

Happy 2010!

Seems appropriate:

“I’m starting to get the sense that 2009 wants to finish me off before it dies of old age. A calendrical unit yelling “I’m taking you with me, you bastard!” from its vanishing final paper bunker marked December, every spent day a room deleted from the structure until 2009 is finally huddled in one small box marked 31 and screaming obscenities in stark terror.”

The Dangers of Wanton Money Printing

Interesting commentary in the UK on QE:

“The truth is, though, that we have been living in an economic La La Land, induced by perhaps the biggest policy undertaken during the Labour Government’s period in office: printing money, or quantitative easing, to use its economically correct but unlovely name.

The way QE works is like this. The Bank of England is owned by Her Majesty’s Government and the Chancellor has given it permission to create £200 billion of what is known as “central bank money”. Rather than physically print the notes at its works in Debden in Essex, it has simply been buying up Government bonds, or gilts, from investors and crediting electronically the accounts of their bankers.

What happens now? At times like these, history can be a useful guide and I am afraid the precedents are rather scary. Printing money has been used before as an emergency monetary policy: during the Napoleonic Wars; in the 1820s; and during the First World War. On two out of three of those occasions the authorities overdid it and the result was inflation, followed by a second crash, when the printing presses were turned off rather clumsily.”

Worth perusing . . .

Stiglitz: 6 Harsh lessons We Failed to Learn

Email this post Print this post
By Barry Ritholtz - December 31st, 2009, 8:30AM

Economics Nobel laureate and Columbia University professor Joseph E. Stiglitz has what very well be the best year end piece I have seen to date;

“The best that can be said for 2009 is that it could have been worse, that we pulled back from the precipice on which we seemed to be perched in late 2008, and that 2010 will almost surely be better for most countries around the world. The world has also learned some valuable lessons, though at great cost both to current and future prosperity – costs that were unnecessarily high given that we should already have learned them.”

What were those 6 “harsh” lessons?

1. Markets are not self-correcting, and without adequate regulation, they are prone to excess.

2. There are many reasons for market failures. Too-big-to-fail financial institutions had perverse incentives: Privatized gains, socialized losses. .

3. When information is imperfect, markets often do not work well – and information imperfections are central in finance.

4. Keynesian policies do work. Countries, like Australia, that implemented large, well-designed stimulus programs early emerged from the crisis faster

5. There is more to monetary policy than just fighting inflation. Excessive focus on inflation meant that some central banks ignored what was happening to their financial markets. The costs of mild inflation are miniscule compared to the costs imposed on economies when central banks allow asset bubbles to grow unchecked.

6. Not all innovation leads to a more efficient and productive economy – let alone a better society. Private incentives matter, and if they are not properly aligned, the result can be excessive risk taking, excessively shortsighted behavior, and distorted innovation.

Why this was published in the China Daily, and not in the US is beyond my understanding . . .

Markets on track to end in the direction of the ’09 trend

Email this post Print this post
By Peter Boockvar - December 31st, 2009, 8:18AM

We are on track to finish the yr with the trends that have been in place 3/4 of ’09, strong stocks and corporate debt, weak US$ and lower US treasuries. The credit markets led the way down in ’08 in terms of equity performance, up in ’09 and I believe will again dictate the direction in ’10, particularly the sovereign side, which now includes half of the entire mortgage debt in the US. The Yuan partially reversed yesterday’s sharp move up after Chinese officials said economic policy will remain on track. Helping to send the US$ index to a 2 week low is a better than expected home price gain in the UK which is sending the pound higher by almost 1%. Initial Jobless Claims are expected to total 460k and will be impacted by the difficulty in seasonally adjusting data this time of the yr. If the economy continues to improve, ’10 will see job growth but will it be enough to lower the unemployment rate and will the longer term unemployed find work?

What Would Cause a 5.50% 10-Year Note Next Year?

Email this post Print this post

What Would Cause A 5.50% 10-Year Note Next Year?

  • Bloomberg.com – Morgan Stanley Sees 5.5% Note as U.S. Faces Deficits
    If Morgan Stanley is right, the best sale of U.S. Treasuries for 2010 may be the short sale.
    Yields on benchmark 10-year notes will climb about 40 percent to 5.5 percent, the biggest annual increase since 1999, according to David Greenlaw, chief fixed-income economist at Morgan Stanley in New York. The surge will push interest rates on 30-year fixed mortgages to 7.5 percent to 8 percent, almost the highest in a decade, Greenlaw said.Investors are demanding higher returns on government debt, boosting rates this month by the most since January, on concern President Barack Obama’s attempt to revive economic growth with record spending will keep the deficit at $1 trillion. Rising borrowing costs risk jeopardizing a recovery from a plunge in the residential mortgage market that led to the worst global recession in six decades. “When you take these kinds of aggressive policy actions to prevent a depression, you have to clean up after yourself,” Greenlaw said in a telephone interview. “Market signals will ultimately spur some policy action but I’m not naive enough to think it will be a very pleasant environment.”Yields on the 3.375 percent notes maturing in November 2019 climbed 4 basis points to 3.84 percent at 11 a.m. in London today, according to BGCantor Market Data. The price fell 10/32 to 96 5/32. They have risen 65 basis points this month, the most since April 2004, as government efforts to unfreeze global credit markets lessened the appeal of the securities as a haven. … Edward McKelvey, senior economist in New York at Goldman Sachs Group Inc., the top-ranked U.S. economic forecasters in 2009, according to data compiled by Bloomberg, expects yields to drop to 3.25 percent. Goldman Sachs says unemployment will average 10.3 percent in 2010, hindering the recovery.

Comment

The story above says a 5.50% 10-year yield would be the “the biggest annual increase since 1999, according to David Greenlaw, chief fixed-income economist at Morgan Stanley in New York.“  We are not sure what he means by this.  If he means a rise in yields from 3.84% (current) to 5.50% would be a 166 (basis points) bps rise in yields, the largest since 1999, technically he is correct.  However, the 10-year started the year at 2.24% and has risen 160 bps already year-to-date.  Should the 10-year yield rise another three bps this week, then a rise to 5.50% next year would be smaller than this year’s increase in yields.  Morgan Stanley is trying to get our attention with an eye-popping statistic to get the point across that next year will be a bad year for Treasury market investors.

We bring this up not to be picky, but to point out that 2009 is going to be long-term Treasury securities’ worst total return year ever.  Year-to-date (YTD) the 10-year is down 10.2% (the 30-year is down an incredible 24% YTD).  These are by far the worst total returns ever seen in the fixed-income market for one year.  Reliable data started in 1927.

If Morgan Stanley is trying to say that 2010 will be a disaster for Treasury investors, here is some news for them, 2009 was a disaster in proportions never before seen.  So, are they looking at what has happened and projecting that it will happen again?

What Do We Think?

The chart below shows the last decade of 10-year yields.  A move to 5.50% (gray horizontal line) would be near a 10-year high.

<Click on chart for larger image>

We believe that such a move is entirely possible on the back of runaway inflation fears.  The next chart below shows TIPS 10-year inflation breakeven levels.  Note that in recent weeks inflation expectations have been going vertical and are now at 2.40%.

<Click on chart for larger image>

Inflation expectations are up almost 250 bps since the start of the year, far more than the 160 bps rise in nominal 10-year yields.   Should 10-year yields go to 5.50% by the end of next year, we would expect it to be accompanied by a huge rise in inflation expectations.  Back-of-the-envelope calculations would put the 10-year inflation breakeven rate near 4.00%, an all-time high (its current record high, which is not shown above, was 3.32% set the week after TIPS were first introduced in February 1997).

In other words, a rise to 5.50% would mean that TIME’s Person of the Year (Bernanke) was an utter failure in 2010, as is often the case the year after one is awarded POY.  The exit strategy will have been botched and the world will be close to hyperventilating about inflation coming back.  Julian Robertson’s prediction of 20% inflation will not look so laughable anymore.

This scenario is certainly possible if the Federal Reserve continues to flood the market with easy money, thus fueling inflation fears.  In other words, this can happen if the Federal Reserve continues to botch the exit strategy (not botching the exit strategy means to withdraw the excess liquidity before heightened inflation expectations take hold and without causing financial market instability) .  Higher inflation is something we have frequently worried about and we believe is the foundation of Morgan Stanley’s forecast.

Of course Morgan Stanley cannot say this out loud because they need access to the Federal Reserve.  The Fed comes down very hard on mainstream forecasters that say anything bad about them.
