MH17. Why planes and financial systems crash

What does the crash of Malaysia Airlines flight MH17 have to do with the global financial crisis?

One was destroyed by a surface-to-air-missile, the other came about because huge numbers of American housing loans became worthless at once. Enabling each was a bet that the unlikely wouldn’t happen.

It’s usually a good bet.

Qantas, Korean Air, and Taiwan's China Airlines weren't prepared to take it. They rerouted their flights to avoid the Ukraine months ago. Their caution cost them fuel, travelling time and profits.

Airlines such as Malaysia, Singapore and Lufthansa took a punt.

“What logic, what lack of sensitivity, and what lack of basic decency influenced Singapore Airlines and Malaysia Airlines and others to expose their passengers to these risks?” asked aviation journalist Ben Sandilands on his blog Plane Talking.

The logic was that the unlikely probably wouldn’t happen, or at least wouldn’t to them. Being slaughtered while flying well above a war zone is what experts call a low-probability, high-impact event.

Coldly risking something catastrophic in the knowledge that it almost certainly won’t happen (at least not to you) is a way to deliver superior financial returns, right up the point when it is not. And it’s rife in the finance industry.

Fund managers get paid for performance. Well ahead of the financial crisis in early 2008 two academics from Oxford and Pennsylvania universities demonstrated that it was possible for a fund manager to consistently deliver superior performance by betting the fund that an unlikely catastrophic event wouldn’t happen.

If, as was highly likely, the catastrophe never occurred the bet would pay off and they would be rewarded for their superior performance. If it eventually did occur they would have already received their bonuses and could leave the fund to collapse, moving on to a new job.

Because fund managers keep their methods secret professors Peyton Young and Dean Foster said it was “virtually impossible to set up an incentive structure that rewards skilled hedge fund managers without at the same time rewarding unskilled managers and outright con artists”.

As they put it, “anyone can cobble together a car that delivers apparently superior performance for a period of time and then breaks down completely”. Airlines can do it, privatised electricity suppliers can do it by not investing in maintenance as Victoria has discovered to its cost during brownouts, and state governments can do it by continuing to allow building in flood prone locations as Queensland did before its most recent devastating flood.

The entire world can do it by acting as if climate change won’t be too serious (although that’s probably better described as a medium to high probability high-impact event).

And the manufacturers of financial products can do it...

In the leadup to the global financial crisis they created products sprinkled with loans that could never be repaid if housing prices fell. But they bet that prices wouldn’t fall, not all at once. Compliant ratings agencies produced estimates of how unlikely such an event was. When it happened the products and the financial institutions that created them became worthless. The government rescued the important ones and much of the world slid into recession.

There’s no quick fix to stop it.

Part of the solution is better regulation, something the world’s financial authorities are on to after the global financial crisis. But regulation usually only closes a door after a crisis. Then a different unforeseeable event occurs creating another crisis creating another regulation.

As strange as it seems rewards for performance are probably a bad idea. They are what encouraged reckless practices in the United States. If Qantas schedulers were paid bonuses for speed they might have been keener to flirt with danger.

On the other hand real ownership could help. Paying employees in shares that couldn’t be cashed in for years would encourage them to be careful, as would requiring maintenance engineers to engrave their names of the fuselage of the planes they repair - a practice that is said to take place in Japan.

The best antidote is probably a rigorous cost benefit and risk analysis performed by someone whose pay cheque doesn’t depend on the next month’s profit.

The Coalition embraced such an idea in its September election policy. All Commonwealth infrastructure spending exceeding $100 million was to be “subject to analysis by Infrastructure Australia to test cost-effectiveness and financial viability”. Even state government projects only partially supported by the Commonwealth were to face Infrastructure Australia scrutiny.

No longer. On Thursday the government rejected a Senate resolution that would have given effect to its own policy. Labor moved that the reward payments made to states that privatise assets and then use the proceeds for new projects be subject to Infrastructure Australia cost benefit analysis. It would have covered the Metro Rail project and anything else funded by the sale of right to use the Port of Melbourne.

The Coalition said no.

Commonwealth cost benefit statements were “red tape with no additional benefit”. They risked delaying “the delivery of critical infrastructure”. They would “stand in the way of the government building a stronger more prosperous economy and investing in new infrastructure,” according to the finance minister Mathias Cormann.

But when lots of money or lives are at stake, delay is often a good idea. There’s a lot to be said for caution.

What's conservative?

Garnaut tackles this question in his report.

“Many would argue that the uncertainty requires a conservative rather than ambitious approach to mitigation. But what is conservative in a context where the possible outcomes include some that most humans today would consider catastrophic? Conservatism may in fact require erring on the side of ambitious mitigation. After all, prudent risk management would suggest that it is worth the sacrifice of a significant amount of current income to avoid a small chance of a catastrophic outcome.”

I can see his point.

A conservative would take out fire insurance even if they thought there was only a small chance of their house burning down.

Sunday dollars+sense: You don't really want to be really rich

What if this past week you made the most stupid New Year’s resolution of them all You promised to make yourself really rich.

I’m here to deliver the bad news. You won’t do it - you don’t have the courage.

Let’s look at the behaviour of contestants on Channel Nine’s Who Wants To Be A Millionaire quiz show...

Until Sydney’s Rob Fulton took the prize in 2005 not an single contestant in a decade of shows had had the courage. Nine had been offered a chance to answer the million-dollar question. All nine had baulked, preferred to walk away with half that rather than risk it.

British economist Ian Walker examined the behaviour of UK contestants in a study entitled "Who Really Wants to be a Millionaire?"

He found that most of the 500 contestants he studied quit while they were ahead. Almost all quit when their winnings reached £125,000 (about $300,000).

Away from the pokies are notoriously and unreasonably cautious when we are offered even small gambles.

If I offer you a 50-50 bet: heads you win $200; tails you lose $150 – you should accept. It’s a brilliant deal. But most people won’t.

A few years back economist Baba Shiv and a team from Iowa University gave a roomful of locals $20 each and offered them 20 chances to bet with it on the toss of a coin, risking $1 each time but knowing they would make more than $1 each time it came up heads.

Another brilliant deal. But the locals accepted only half of the time.

Then he did something bizarre. He performed the same test on a group of Iowa residents who had either suffered a stroke or survived brain surgery. What they had in common was a damaged prefrontal cortex, the part of the brain that processes emotions.

The brain-damaged individuals turned out to be much better investors than the Iowa residents with brains intact. Given $US20 each and the same 20 chances to accept the attractive bet, they accepted more than 80 per cent of the time. They did better than their counterparts with undamaged brains.

When the study was published in the journal Psychological Science the newspaper reports were sensational. One asked: "Are successful investors emotionally brain damaged”.

But that’s not the point.

The point is that there is something about our emotions that makes us cautious when it comes to risking our winnings – too cautious from a coldly calculating point of view.

That’s why neither of us will ever be really rich.
