Economists Are (Still) Clueless

By John Mauldin | Jun 15, 2013 / The Economist

The Revenge of Minksy Moment.

Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is past the ocean is flat again.
- John Maynard Keynes, A Tract on Monetary Reform
There can be few fields of human endeavor in which history counts for so little as in the world of finance. Past experience, to the extent that it is part of memory at all, is dismissed as the primitive refuge of those who do not have insight to appreciate the incredible wonders of the present.
- John Kenneth Galbraith
Hitler must have been rather loosely educated, not having learned the lesson of Napoleon's autumn advance on Moscow.

Economists Are (Still) Clueless
In November of 2008, as stock markets crashed around the world, the Queen of England visited the London School of Economics to open the New Academic Building. While she was there, she listened in on academic lectures. The Queen, who studiously avoids controversy and almost never lets people know what she's actually thinking, finally asked a simple question about the financial crisis: "How come nobody could foresee it?" No one could answer her.
If you've suspected all along that economists are useless at the job of forecasting, you would be right. Dozens of studies show that economists are completely incapable of forecasting recessions. But forget forecasting. What's worse is that they fail miserably even at understanding where the economy is today. In one of the broadest studies of whether economists can predict recessions and financial crises, Prakash Loungani of the International Monetary Fund wrote very starkly, "The record of failure to predict recessions is virtually unblemished." He found this to be true not only for official organizations like the IMF, the World Bank, and government agencies but for private forecasters as well. They're all terrible. Loungani concluded that the "inability to predict recessions is a ubiquitous feature of growth forecasts." Most economists were not even able to recognize recessions once they had already started.
In plain English, economists don't have a clue about the future.
If you think the Fed or government agencies know what is going on with the economy, you're mistaken. Government economists are about as useful as a screen door on a submarine. Their mistakes and failures are so spectacular you couldn't make them up if you tried. Yet now, in a post-crisis world, we trust the same people to know where the economy is, where it is going, and how to manage monetary policy.
Central banks say they will know the right time to end the current policies of quantitative easing and financial repression and when to shrink the bloated monetary base. However, given their record at forecasting, how will they know? The Federal Reserve not only failed to predict the recessions of 1990, 2001, and 2007, it also didn't even recognize them after they had already begun. Financial crises frequently happen because central banks cut interest rates too late and hike rates too soon.
Trusting central bankers now is a big bet that (1) they'll know what to do, (2) they'll know when to do it. Sadly, given the track record, that is not a good wager. Unfortunately, the problem is not that economists are simply bad at what they do; it's that they're really, really bad. They're so bad that it cannot even be a matter of chance. The statistician Nate Silver points this out in his book The Signal and the Noise:
Indeed, economists have for a long time been much too confident in their ability to predict the direction of the economy. If economists' forecasts were as accurate as they claimed, we'd expect the actual value for GDP to fall within their prediction interval nine times out of ten, or all but about twice in eighteen years.
In fact, the actual value for GDP fell outside the economists' prediction interval six times in eighteen years, or fully one-third of the time. Another study, which ran these numbers back to the beginning of the Survey of Professional Forecasters in 1968, found even worse results: the actual figure for GDP fell outside the prediction interval almost half the time. There is almost no chance that economists have simply been unlucky; they fundamentally overstate the reliability of their predictions.
So economists are not only generally wrong, they're overly confident in their bad forecasts.
If economists were merely wrong at betting on horse races, their failure would be amusing. But central bankers have the power to create money, change interest rates, and affect our lives in multiple ways – and they don't have a clue.
Despite this, they remain perennially confident. There's no overestimating the hubris of central bankers. On 60 Minutes in December, 2010, Scott Pelley interviewed Fed Chairman Ben Bernanke and asked him whether he would be able to do the right thing at the right time. The exchange was startling (at least to us):
Pelley: Can you act quickly enough to prevent inflation from getting out of control?
Bernanke: We could raise interest rates in 15 minutes if we have to. So, there really is no problem with raising rates, tightening monetary policy, slowing the economy, reducing inflation, at the appropriate time. Now, that time is not now.
Pelley: You have what degree of confidence in your ability to control this?
Bernanke: One hundred percent.
There you have it. Bernanke was not 95% confident, he was not 99% confident – no, he had zero doubts about his ability to know what is going on in the economy and what to do about it. We would love to have that sort of certainty about anything in life.
We're not just picking on Bernanke; we're picking on all central bankers who think they're infallible. The Bank of England has had by far the largest QE program relative to the size of its economy (though the Bank of Japan is about to show it a thing or two). It also has the worst forecasting track record of any bank, and the worst record on inflation. Sir Mervyn King, the head of the Bank of England, was asked if it would be difficult to withdraw QE. He very confidently replied, "I have absolutely no doubt that when the time comes for us to reduce the size of our balance sheet that we'll find that a whole lot easier than we did when expanding it." (Are central bankers just naturally more overconfident than regular human beings, or are they smoking some powerful stuff at their meetings?)
Let's see whether this sort of absolute certainty is in any way warranted.
In his book Future Babble, Dan Gardner writes that economists are treated with the reverence the ancient Greeks bestowed on the Oracle of Delphi. But unlike the vague pronouncements from Delphi, economists' predictions can be checked against the future, and as Gardner says, "Anyone who does that will quickly conclude that economists make lousy soothsayers."
The nearsightedness of economists is nothing new. In 1994 Paul Ormerod wrote a book called The Death of Economics. He pointed to economists' failure to forecast the Japanese recession after their bubble burst in 1989 or to foresee the collapse of the European Exchange Rate Mechanism in 1992. Ormerod was scathing in his assessment of economists: "The ability of orthodox economics to understand the workings of the economy at the overall level is manifestly weak (some would say it was entirely non-existent)."
When most people think of economic forecasts, they almost always think of recessions, while economists think of forecasting growth rates or interest rates. But the average man in the street only wants to know, "Will we be in a recession soon?" And if the economy is actually in a recession he wants to know, "When will it end?" The reason he cares is that he knows recessions mean job cuts and firings.
Recessions lead to falls in GDP and spikes in the unemployment rate:
Unfortunately, economists are of little use to the man in the street. If you look at the history of the last three recessions in the United States, you will see that the inability of economists and central bankers to understand the state of the economy was so bad that you might be tempted to say they couldn't find their derrieres with both hands.
Economists have yet to corrrectly call a recession:
Let's remind ourselves what a recession is and how economists decide that one has started. A recession is a downturn in economic activity. Normally, a recession means unemployment goes up, GDP contracts, stock prices fall, and the economy weakens. The lofty body that decides when a recession has started or ended is the Business Cycle Dating Committee of the National Bureau of Economic Research. It is packed with eminent economists – all extremely smart people. Unfortunately, their pronouncements are completely unusable in real time. Their dating of recessions is authoritative and more or less accurate, but this exercise in hindsight comes long after a recession has started or ended.
To give you an idea just how late recessions are officially called, let's look at the past three. The NBER dated the 1990-91 recession as beginning in August 1990 and ending in March 1991. It announced these facts in April 1991, by which time the recession was already over and the economy was growing again. The NBER was no faster at catching up with the recession that followed the dotcom bust. It wasn't until June 2003 that the NBER pinpointed the start of the 2001 recession – a full 28 months after the recession ended. The NBER didn't date the recession that started in December 2007 until exactly one year later. By that time, Lehman had gone bust, and the world was engulfed in the biggest financial cataclysm since the Great Depression.
The Federal Reserve and private economists also missed the onset of the last three US recessions – even after they had started. Let's look quickly at each one.
Starting with the 1990-91 recession, let's see what the head of the Federal Reserve – the man who is charged with running American monetary policy – was saying at the time. That recession started in August 1990, but one month before it began Alan Greenspan said, "In the very near term there's little evidence that I can see to suggest the economy is tilting over [into recession]." The following month – the month the recession actually started – he continued on the same theme: "... those who argue that we are already in a recession I think are reasonably certain to be wrong." He was just as clueless two months later, in October 1990, when he persisted, "... the economy has not yet slipped into recession." It was only near the end of the recession that Greenspan came around to accepting that it had begun.
The Federal Reserve did no better in the dotcom bust. Let's look at the facts. The recession started in March 2001. The tech-heavy NASDAQ Index had already fallen 50% in a full-scale bust. Even so, Chairman Greenspan declared before the Economic Club of New York on May 24, 2001, "Moreover, with all our concerns about the next several quarters, there is still, in my judgment, ample evidence that we are experiencing only a pause in the investment in a broad set of innovations that has elevated the underlying growth rate in productivity to a level significantly above that of the two decades preceding 1995."
Charles Morris, a retired banker and financial writer, looked at a decade's worth of forecasts by the professionals at the White House's Council of Economic Advisers, the crème de la crème of academic economists. In 2000, the council raised their growth estimates just in time for the dot-com bust and the recession of 2001-02. And in a survey in March 2001, 95% of American economists said there would not be a recession. (John forecast it in September 2000 in this letter). The recession had already started that March, and the signs of contraction were evident. Industrial production had already been contracting for five months.
You would have thought that failure to forecast two recessions in a row might have sharpened the wits of the Federal Reserve, the Council of Economic Advisers, and private economists. Maybe they would have tried to improve their methods or figured out why they had failed so miserably. You would be wrong. Because along came the Great Recession, and once again they completely missed the boat.
The Revenge of the Minsky Moment
Let's look at what the Fed was doing as the world was about to go up in flames in 2008. Recently, complete minutes of the Fed's October 2007 meeting were released. Keep in mind that the recession started two months later, in December. The word recession does not appear once in the entire transcript.
It gets worse. The month the recession started, the Federal Reserve was all optimistic laughter. Dr. David Stockton, the Federal Reserve chief economist, presented his views to Chairman Bernanke and the meeting of the Federal Open Market Committee on December 11, 2007. When you read the following quote, remember that, at the time, the Fed was already providing ample liquidity to the shadow banking system after dozens of subprime lenders had gone bust in the spring, the British bank Northern Rock had been nationalized and had spooked the European banking system, dozens of money market funds had been shut due to toxic assets, credit spreads were widening, stock prices had started to fall, and almost all the classic signs of a recession were evident. These included an inverted yield curve, which had received the casual attention of New York Fed economists even as it screamed recession. (John had pointed to it numerous times here in Thoughts from the Frontline.)
Read these words of the Fed's Chief Economist and weep. You can't make this stuff up:
Overall, our forecast could admittedly be read as still painting a pretty benign picture: Despite all the financial turmoil, the economy avoids recession and, even with steeply higher prices for food and energy and a lower exchange value of the dollar, we achieve some modest edging-off of inflation. So I tried not to take it personally when I received a notice the other day that the Board had approved more frequent drug-testing for certain members of the senior staff, myself included. [Laughter]
I can assure you, however, that the staff is not going to fall back on the increasingly popular celebrity excuse that we were under the influence of mind-altering chemicals and thus should not be held responsible for this forecast. No, we came up with this projection unimpaired and on nothing stronger than many late nights of diet Pepsi and vending-machine Twinkies.
All other government economists were equally awful. The President's Council of Economic Advisers' 2008 forecast saw positive growth for the first half of the year and foresaw a strong recovery in the second half. Note the date on the cartoon below: May 28, 2008!
Unfortunately, private-sector economists didn't do much better. With very few exceptions, they failed to foresee the financial and economic meltdown of 2008. Economists polled in the Survey of Professional Forecasters also failed to see a recession developing. They forecasted a slightly below -average growth rate of 2.4 percent for 2008, and they thought there was almost no chance of a recession as severe as the one that actually unfolded. In December 2007 a Businessweek survey showed that every single one of 54 economists surveyed actually predicted that the US economy would avoid a recession in 2008. The experts were unanimous that unemployment wouldn't be a problem, leading to the consensus conclusion that 2008 would be a good year.
As Nate Silver has pointed out, the worst thing about the bad predictions isn't that they were awful; it's that the economists in question were so confident in them. Now, this was a very bad forecast: far from growing by 2.4%, GDP actually shrank by 3.3% once the financial crisis hit. Yet these economists assigned only a 3% chance to the economy's shrinking by any margin at all over the whole of 2008, and they gave it only about a 1-in-500 chance of shrinking by 2 percent, as it did.
It is one thing to be wrong; it is quite another to be consistently and confidently and egregiously wrong.
As the global financial meltdown unfolded, Chairman Bernanke, too, continued to believe that the US would avoid a recession. Mind you, the recession had started in December 2007, yet in January '08 Bernanke told the press, "The Federal Reserve is not currently forecasting a recession." Even after banks like Bear Stearns needed to be rescued, Bernanke continued seeing rainbows and candy-colored elves ahead for the US economy. He declared on June 9, 2008, "The risk that the economy has entered a substantial downturn appears to have diminished over the past month or so." At that stage, the economy had already been in a recession for the past six months!
Why do people listen to economists anymore? Scott Armstrong, an expert on forecasting at the Wharton School of the University of Pennsylvania, has developed a "seer-sucker" theory: "No matter how much evidence exists that seers do not exist, suckers will pay for the existence of seers." Even if experts fail repeatedly in their predictions, most people prefer to have seers, prophets, and gurus tell them something – anything at all – about the future.
So, we have cataloged the incredible failures of economists to predict the future or even to understand the present. Now think of the vast powers Fed economists have to print money and move interest rates. When you contemplate the consummate skill that would actually be required to manage post-Great Recession policies, you realize they're really just flying blind. If that reality doesn't scare the living daylights out of you, you're not paying attention.
The longer the Federal Reserve sticks to its current policy, the more likely that policy will end in tears. Call it the Revenge of the Minsky Moment.
