The Hank Paulson plan is quite possibly the most important business plan ever written. It seems it will get tweaked, it may even get tweaked quite a bit, but it will get through.
At the time of writing, it appears all is recrimination. Republicans are blaming Democrats, Democrats are blaming Republicans. Hank Paulson is at once a hero and a villain. Bankers have become evil incarnate, and even America’s poor, with their subprime loans and trailer homes, are getting the blame.
But eventually the blame game will end, and it will dawn on senators that unless some kind of Paulsonesque plan gets through, and gets through quick, the US economy will face catastrophe, and even US politicians will finally see their urgency and need for that, even the ones who double up as hockey mums.
But just because a Paulson-type plan is vital for saving the global economy, it doesn’t mean it is a good plan, it is just the best plan anyone can come up with.
But it does have major flaws: some we are stuck with, some are more serious, some, well, watch them unravel.
When the South Sea Bubble craze was at its height, one business plan famously had the following description: “For carrying-on an undertaking of great advantage but no-one to know what it is!!”
The Paulson plan, by contrast, was written in 21st century speak, but it kind of said the same thing: “Decisions by the Secretary pursuant to this Act are non-reviewable and may not be reviewed by any court of law or any administrative agency.” And oh, by the way, Paulson doesn’t know yet how the money will be spent.
Okay, so US taxpayers, and in a way, the rest of the developed world, have got to trust Hank. So, let’s put our faith in Mr Paulson, he is after all a former chairman of Goldman Sachs, he knows his onions. The likes of George Dubya are just out of their depth, so are most senators. In a way, Paulson is to US politicians what Vince Cable is to Liberal Democrats.
But the snags are these:
First of all, wasn’t it bankers who created the whole mess in the first place? Do you really want an ex-banker to sort it out?
Secondly, Hank will be starting a new job soon; do you really want to charge someone with the responsibility of bailing out banks, when that same person may be looking for a job at one of those banks next year?
Thirdly, isn’t the problem too much pay and too much reward for failure? Isn’t it the problem that bankers have been bailed out every time there is a catastrophe, from Third World debt, the savings and loans disaster, to Tiger economy debt, the Russian crisis, Long Term Capital Management? Isn’t it the problem that banks keep getting it wrong, because they never learn from their mistakes?
Well, all of those arguments may be right, but maybe there is an even deeper problem too. And the problem this time is not so much bankers, politicians, or even economists, this time the guilty part comes in the most innocuous of forms. When you were at school, did you ever know anyone who was brilliant at maths – really brilliant? Not A-grade at Further Level Maths type brilliant, but capable of getting a maths degree at 12 sort of brilliant.
Mathematicians have been running Wall Street.
But this is the snag with mathematicians, they may be good with calculus, or whatever it is that geniuses concern themselves with, but they still make the same old human errors that afflicts us all.
The author, Nassim Taleb put it well in his book The Black Swan. There are two countries in this world, Mediocristan and Extremistan.
In Mediocristan, not much ever happens. There are no surprises. To consider an example of what this country is like, consider a statistical survey to calculate average weight. The survey’s sample is, say, 999 strong. Then it is joined by one other person, but this person just happens to be the heaviest man in the world – how will the average weight be affected? Answer, actually, not that much, even if our fat man weights 100 stones, this will only mean the average weight will be increased by a couple of pounds.
In Extremistan, extreme things happen, and when they happen, the whole calculation is thrown out of kilter. When black swans were discovered in Australia, we had to re-think our definition of what a swan looked like. Or take another example, a statistical survey calculating average wealth. We have our 999 people, and have calculated their average wealth. Say the average comes out at £10,000. Then the list is joined by the word’s richest man, who, right now, is Warren Buffett. Our average person is now worth around £50 million. The extreme event, in this case the inclusion of the word’s richest man in the survey, has completely thrown out the result.
Now consider the world of high finance. Mathematicians make their assumptions based on prevailing conditions. They assume we more or less stay as we are. Risk does not change. We all behave in a certain way, and their view of how we behave is based on how we usually behave.
The mathematicians with their complex algorithms looked at the risk that the banks had insured, and reasoned that since it was insured, failure is highly unlikely. They looked at the laws of chance, and put a probability of systemic collapse at something so small that, by comparison, the one-in-fifty million odds that are supposed to reflect the probability that the Hadron Collider will throw up a black hole which will swallow the Earth, seem high.
In an article in this week’s New Scientist, the whole concept was explained well: “Models typically assume that market prices will continue to behave much as they have in the past, and that they are reasonably predictable,” says the article.
But, it then goes on to to quote William Perraudin, director of the Risk Management Laboratory at Imperial College London who says: “These models mostly overlook how bad news can affect banks’ ability to raise funds. The real risk,” he says, “turns out to be a cycle of drops.”
So, rumours gets out that a bank is in trouble, so others stop lending it money. The fact this bank can no longer borrow money creates problems for the bank, even if the original rumours were wrong. But this in turn can reduce the value of assets at the other banks, and the whole thing goes into a downward spiral.
What these mathematical models are singularly bad at doing is allowing for the fact that the various risks out there relate to each other. If one bank hits trouble, all the banks panic.
What is the probability that all Northern Rock customers will wake up one day and decide to withdraw their money from the bank? Answer: tiny. But the model fails to take into account that one person’s decision to withdraw money can affect someone else’s decision.
It was faulty logic like that that lay behind the Long Term Capital Management failure. That could have ended up as a major banking crisis – but Alan Greenspan gathered together leading banks and orchestrated a bail out. Disaster was avoided, but the lesson was not learnt.
Over the last few years, bankers thought they were living in Taleb’s Mediocristan. In fact, they were living in Extremistan.
Take as another example, the citizens of Pompei in Italy during the Roman Empire. No doubt it never occurred to them that one day the sky would quite literally rain fire, but it did. They too thought they lived in Mediocristan. The mistake the citizens of Pompei and Wall Street made is that they assumed their experience would never change.
In the case of Wall Street, events became self-reinforcing.
Mathematicians erred, and the result has been catastrophe.
The snag with the Paulson plan is this. It is not clear he has understood this. He is assuming that by throwing $700bn into the pot, everything will go back to normal.
But supposing Americans treat their home as if it is a home, rather than a cash cow. Supposing Americans learn to be more cautious with credit spending. Supposing bankers conclude risk has become too risky. With every financial disaster arrests follow. After the South Sea Bubble, the South Sea Company Directors were arrested. It happened again after 1929, it happened earlier this decade.
In Nazi Germany persecution of Jewish bankers turned to the Holocaust.
Right now, if they have any sense at all, bankers are completely changing their attitude to risk.
Who is to say that, post-Paulson plan, everything will be back to normal?
And that is the problem with his plan.
