Why we don't get more joy out of our super

When one of our top econocrats gives a speech about behavioural economics, you know we’re making progress. Take the ever-present problem of income in retirement. “BE” explains both why it’s a major area of government intervention in our lives and how that intervention can be made more effective.

One of the greatest limitations of conventional economics – based on the “neo-classical” model, which focuses on how prices are determined by the interaction of supply and demand – is its assumption that people are unfailingly “rational” – calculatingly self-interested – in their response to the prices they face.

Behavioural economics accepts that we’re not the financial automatons the model assumes us to be, and uses insights from the more empirical sciences of psychology and sociology to gain a much more realistic picture of the many non-monetary factors that also affect our behaviour in economic matters.

Behavioural economists draw on the long list of “heuristics” – mental shortcuts or biases in the way we think – developed by cognitive psychologists. In a recent speech, Dr David Gruen, top economics guy in the Department of Prime Minister and Cabinet, outlined the cognitive biases that limit many people’s ability to make adequate provisions for the income they’ll need in retirement.

For more than a century the government has provided the age pension, of course. But in the 1990s people began to worry that it wouldn’t be sufficient to meet the aspirations of the rising generation. So the Keating government introduced compulsory employee superannuation.

In those days before the spread of BE, most economists accepted the imposition of compulsory saving as a correction to the “market failure” of “myopia” – most of us are too short-sighted to save enough towards our retirement.

The BE way of putting it is that we suffer from “present bias” – we overvalue the present relative to the future. Gruen takes the idea further, noting that “while choosing a retirement plan is likely to influence literally decades of our lives, many of us spend little time – sometimes less than an hour – choosing our plan”.

Then there’s “confirmation bias” – we tend to remember events that confirm our existing views, but forget developments that cast doubt on those views. Gruen uses this to explain why many of us spend what little time we have set aside to choose a retirement plan looking for one with an investment strategy that supports our existing investing approach.

And “cognitive overload”. This occurs when people find it too hard to process a mass of information in order to make decisions. In the context of planning for retirement, it leads many of us to stick with choices we have arrived at by default.

“Together, these cognitive biases create a big gap between our intentions and our actions: although people intend to save for their retirement, they often don’t translate that into action. For most people, how much to save, and in what form, are difficult cognitive problems – because of both our limited calculation powers and the apparent enormity of the task,” Gruen says.

When the compulsory super system was first set up, the government adopted the conventional economics view that savers were rational economic agents who knew their own business best. So all it had to do was require the super funds to reveal relevant information about their investment options, and diligent savers would do the rest, ensuring they picked the option that best suited their circumstances.

Yeah sure. At the time of a review of super in 2009, 80 per cent of super fund members were invested in the default fund chosen by their employer. Of that 80 per cent, anecdotal evidence suggested that only about 20 per cent explicitly chose the default option, with the rest making no active choice whatsoever.

“When complicated decisions are required, people often stick with the status quo and take no decision at all. In that case, the default option becomes very important,” Gruen says. (This is actually one of the key “insights” of BE.)

So the review panel recommended creating a default option – called MySuper - with features that would promote the wellbeing of those who didn’t actively choose another option. MySuper funds must be simple and cost-effective, with a diversified portfolio of investment.

Of course, there are remaining challenges in the compulsory super system, which the latest review of retirement incomes, instigated by Treasurer Josh Frydenberg, will consider. Let’s hope it takes full advantage of the behavioural insights available to it.

As Gruen says, BE allows all government policymaking to be improved by starting with a richer understanding of human behaviour and building this into the design of measures.

Governments are learning to nudge us down better paths

The world is a complicated place – partly because humans are complicated animals. One of the many things this means is that when governments try to influence our behaviour, their chances of stuffing up are surprisingly high.

Consider this. Say I’m an investment adviser telling you (or your parents or grandparents) where to invest your retirement savings. I warn you that, should you take my advice, I’ll be paid a commission by the managers of the investments I put you into.

How do you react?

Well, you should react by becoming a lot more cautious about following my advice. It’s clear I have a conflict of interest. Is my advice aimed at doing the best I can for you, or at maximising the commissions I earn?

When governments require investment advisers to disclose any conflict of interest to their clients, that’s how the pollies expect you’ll react. They also expect that this requirement will prompt advisers to eliminate or reduce any conflict so their advice is more likely to be trusted.

But research by Dr Sunita Sah, a psychologist at Cornell University in upstate New York, has found it often doesn’t work like that. Although such disclosures do indeed cause clients to have less trust, they can often lead people to feel social pressure to act on the advice anyway.

Clients may be concerned that refusing to follow the advice would be a signal of their distrust in the adviser, with whom they’ve often formed a personal bond. They may even interpret the disclosure as a request that the advice be taken, as a favour to the adviser who, after all, needs to earn a living like the rest of us.

Sah found that clients given advice they knew to be conflicted were twice as likely to follow that advice as were clients where no disclosure was made.

The lesson is not that we should stop requiring advisers to disclose their conflicts, but that government policymakers need to think carefully about the specific design of their policies.

It turns out you can reduce the undesirable effects of disclosure if they come from a third party – that is, someone other than the adviser. It also helps if clients’ decisions are made in private, or if there’s a cooling-off period before the decision is finalised.

Have you guessed where this is leading? It’s a plug for a relatively new tool that’s been added to the bureaucrats’ policy toolkit – “behavioural insights”.

In a speech he gave in Canada last week, Dr David Gruen, a deputy secretary in our Department of Prime Minister and Cabinet, explained that behavioural insights is an approach to policymaking that draws from psychology, cognitive sciences and economics to better understand human behaviour, help people make good choices more easily, and help improve the effectiveness of public policy interventions.

As the case of conflict-of-interest disclosures illustrates, people’s responses to government policy measures can be surprising. Politicians and bureaucrats need to be more conscious of the insights of behavioural insights when designing policies to fix problems.

And the behavioural insights tool can also be used for real-world testing of how policy measures are working – or not working – in practice.

The first government to establish a behavioural insights team was Britain in 2010, at the initiative of prime minister David Cameron, Gruen says. It’s since become a partly privatised joint venture.

By now, according to the Organisation for Economic Co-operation and Development, there are more than 200 public sector organisations around the world that have applied behavioural insights to their work.

In Australia, the federal government’s behavioural economics team – BETA – was set up to apply behavioural insights to public policy and to build behavioural-insights capability across the public service. It’s at the centre of a network of 10 behavioural insight teams across the federal government and alongside several state government teams.

These teams are also known as “nudge” units because they’re often trying to give individuals a nudge in the direction of making more sensible decisions, while leaving them free to do something else should they choose. You’re not forced, just nudged.

Gruen offered several examples of what the feds have been doing. BERT, the behavioural economics research team in the Department of Health, looked at the ballooning cost of reimbursements to doctors for providing after-hours care.

After-hours care considered urgent was remunerated at about twice the rate of that judged a non-urgent visit. Who judged whether the care was urgent? The doctor.

The department identified the 1200 doctors with the highest urgent after-hours claims, and ran a randomised control trial, sending each of them one of three alternative letters, with the letter a doctor received chosen at random.

One letter compared the doctor’s billing practices with their peers, showing they were claiming the urgent category far more often than others were. This drew on the behavioural insight that individuals are often motivated to change their behaviour when they are out of step with their peers.

The second letter emphasised the consequences of non-compliance, including the penalties and legal action. This letter drew on the behavioural insight that people tend to avoid losses more than they seek the equivalent gains.

The third letter was the control – the standard bureaucratic compliance letter, running to three pages.

All three letters were successful in reducing claims, but the peer-comparison one was far more effective than either the standard compliance letter or the loss-framing letter. The peer-comparison letter reduced claims by 24 per cent.

And it was just a nudge, not a threat of punishment for dishonestly claiming cases to be urgent when they weren’t.

In the six months after the letters were sent, the 1200 high-claiming doctors reduced their claims by more than $11 million (across all three letters), and 18 doctors voluntarily owned up to more than $1 million in previous incorrect claims.

So, as Gruen concludes, a simple and cheap nudge can yield big dividends.

If you’re virtuous, don’t be afraid to signal it to the world

I’m troubled by the fashion of accusing others of “virtue signalling”. This world could use more virtue and less vice. And if people want others to see their virtue, well, there are worse sins.

Usually, it’s an accusation hurled at those on the other side of the political fence as a way of impugning their motives. They’re not genuinely virtuous, they just want people to think they are when they’re not.

They want to be seen as better than we are. They want me to feel guilty for not being as good as them, but I’m not buying that. I may be motivated by self-interest in the government policies I advocate, but so are they – they’re just pretending otherwise.

You can rationalise such a response by using the assumption of the neo-classical economic model that economic agents (you and me) are always and only motivated by self-interest. Altruism doesn’t exist. When I help someone, I’m doing so only because it makes me feel good.

In truth, social psychology has found plenty of evidence for the existence of altruism. It’s associated with another truth: homo sapiens’ success as a species is owed as much to co-operation as to competition.

I remember how shocked I was years ago to hear a top Treasury official refer with contempt to the Australian Council of Social Service – the peak body representing welfare organisations, including the Salvos – as “the compassion industry”.

First time I’d heard that word used as a term of derision. It reminded me of a song we sang when I was a Salvo: “Except I am moved with compassion, how dwellest Thy Spirit in me?”.

The Treasury man’s claim was that the ACOSS people didn’t really care about the poor and needy, they’d just found a way to make their living by representing the interests of poor. They were no more than another lobby group with their hand out.

As social animals, humans form themselves into tribes – groups. We have a compulsion to divide the world into good guys and bad guys. Naturally, my group are the goodies but, unfortunately, your group are the baddies.

Each of us sees ourselves as good, but some others as bad. I’m genuinely virtuous, whereas you’re just pretending to be.

In truth, none of us is all good or all bad. All of us are good in some respects and bad in others. And psychologists tell us we’re all often guilty of hypocrisy – applying high standards in judging others’ behaviour while making excuses for our own.

Equally, much of what we do we do for mixed motives. Try this test (one I usually fail): when you’re giving money to charity, how do you answer when asked if you’d like your donation to remain anonymous?

It’s possible some of us do virtuous acts – or make statements in support of virtuous policies – without any genuine interest in the wellbeing of others. It’s possible, but I doubt it’s very common.

What’s much more likely is mixed motives: we’re genuine in our professed concern about others, but equally genuine in our desire to be seen by others as having such a concern. That’s not really hypocritical, just being human.

Because we’ve evolved as group animals, all of us care deeply about what others think of us. We want to be accepted by the other members of the group. And we fear being excluded from the group.

Like teenagers, we’re desperate to fit in. The more we look and act like the others, the more comfortable we feel.

(This points to a further weakness in the neo-classical model: its assumption that each of us is a rugged individualist who makes decisions – about what movie to see or what clothes to buy – totally without reference to what those around us are doing.)

Turns out humans are signalling animals. We’re always using what we do, what we say, the way we dress, to signal our virtues to others – including our conformity to the group’s norms of acceptable behaviour.

The economy abounds with people and businesses sending signals. The first three economists to realise this won the Nobel prize for their genius.

We resort to sending signals because neither we nor others have enough hard information about the people we deal with and who deal with us. The main message we send is: you can trust me to deal with you honestly.

In today’s economy we’re suffering from a loss of trust, caused by a lack of virtuous behaviour, which has damaged reputations. We need economic behaviour to be a lot more virtuous. As that virtue is signalled, others will join in and the group norm of acceptable behaviour will be restored.

How canny treasurers keep the tax we pay out of sight

We can be sure that tax and tax “reform” will be a big topic (yet again) this year, but what will get less attention is how behavioural economics explains the shape of the existing tax system and makes it hard to change.

I read that this year we may attain the economists’ Holy Grail of replacing state conveyancing duty with a broad-based annual tax on the unimproved value of land under people’s principal residence.

Economists regard taxing homes whenever they change hands as highly economically inefficient because it discourages people from moving when they need to move, whereas taxing the ownership of land as highly efficient because it’s hard to avoid and is naturally “progressive”, hitting the rich harder than the poor.

Holy grails are, however, wondrous things, but almost impossible to attain. Economists have been preaching the virtues of such a switch for at least the past 30 years, with precious few converts (bar, in recent times, the ACT government).

Why have state politicians been so unreceptive to such a patently good idea? Because politicians instinctively understand what most conventional economists don’t: the wisdom of Louis XIV’s finance minister’s declaration that “the art of taxation consists in so plucking the goose as to obtain the largest possible amount of feathers with the smallest possible amount of hissing”.

Or, to put it another way, because conventional economists don’t know enough behavioural economics – the study of how the world actually works thanks to human fallibility, rather than how it would work if we were all as rational as economic textbooks assume us to be.

A central element of the political economy of taxation is that what the punters don’t notice they don’t worry about.

And to every revenue-hungry state treasurer (which is all of ’em), the great virtue of conveyancing duty is that when you’re buying a place for $1 million and someone presents you with a tax bill for $40,000, it looks a relatively small amount and the least of your worries right now.

By contrast, when you open your mail one day and find the government demanding to be paid, say, $5000, you tend to get resentful. Because we’ve spent all our lives in a market economy, we’re used to the notion that, if you want something, you have to pay for it.

And with the converse: you don’t shell out good money without getting something you want in return. Annual land tax breaches that rule: you write a cheque for five grand and just post it off into the void. (This was also part of the reason the old “provisional tax” was so unpopular.)

Behavioural economists demonstrate empirically what politically astute treasurers know instinctively: you greatly reduce the hissing if you can whip the tax away without it being seen. This is why, when introducing the goods and services tax, Peter Costello wrote into the act the requirement that retail prices be quoted inclusive of the tax, without the tax being shown separately.

Of course, for wage earners, personal income tax has worked that way for decades. The pay office extracts an estimate of the tax you’ll have to pay and sends it to the taxman before you even see your pay.

After a while, you pretty much forget you’re paying tax on much of what you buy and are being paid much less than you’re earning. Which also demonstrates the wisdom of a saying familiar to treasurers: a new tax is a bad tax; an old tax is a good tax.

We object loudly to almost all proposals for new taxes – land tax on the family home, a road congestion tax and many more. We spent 25 years working up the courage to impose a value-added tax on “almost everything we buy” (during which time we copied the Kiwis’ crafty idea of renaming it the more innocuous “goods and services tax”).

But here’s the trick: once the new tax has been passed and taken effect, it takes only a year or two for us to accept it as part of the furniture. Behavioural economists call this quirk of human nature “status-quo bias”.

And, of course, just about the oldest tax of all is what Malcolm Fraser used to call “the secret tax of inflation” aka bracket creep.

It’s the tax increase you have when you don’t like tax increases.

Our “revealed preference” (not what we say, but what we do) is that bracket creep's our favourite tax.

Which is why treasurers of both colours give us so much of it.

Does gift-giving make sense? Silly question

It’s the season of the year when the bylaws of the economists’ union require me to issue the stern admonition that the medieval practice of gift-giving should cease and desist forthwith. And the fact that I’m a bit late won’t stop me.

Perhaps more people - recipients of socks and handkerchiefs and other wondrous surprises - will be receptive to the profession’s utterly disinterested (look it up) advice and see the wisdom of my words.

Gift-giving is an irrational act, one where sentiment and emotion triumph over good sense. Since it’s hardly possible for the giftor better to know what the giftee would like to be given than the giftee themself, the success rate of the practice is abysmally low.

So low, in fact, as to justify economists using one of their worst pejoratives to brand the practice as involving a “deadweight loss” – one where the benefit to the giver and the benefit to the receiver are insufficient to justify the cost of the transaction, thereby creating a loss to the community.

(And please, please don’t ruin my Boxing Day by arguing that the commercialisation of Christmas at least creates jobs. The economists’ union’s Christmastide message is that any mug can create jobs, all you have to do is spend money – your own or someone else’s. The whole point of economics is to help the community spend money in ways that yield it greater benefit than other ways.)

But fear not. Go back to eating your leftovers in peace (and goodwill). I’m not actually a member of the economists’ union, but an adherent to a dissident sect known as behavioural economists (people who, too late in life, realised psychology made more sense than economics).

This bunch of heretics delights in pointing to the glaring weaknesses in the oversimplified model conventional economists carry in their heads.

But you need only to have gone to Sunday school to see the weakness in all the nonsense about the deadweight loss of Christmas. I think it was the little chap himself who said it was more blessed to give than receive.

And there is, in fact, plenty of what a deranged economist would call “giver’s surplus”. How do I know? Because psychological experiments have demonstrated it – many of them conducted by Professor Elizabeth Dunn, a psychologist at the University of British Columbia.

But just last week came new research by Ed O’Brien, of the University of Chicago Booth School of Business, and Samantha Kassirer, of Northwestern University Kellogg School of Management, showing that “the joy of giving lasts longer than the joy of getting”.

One of the great limitations of human nature is “hedonic adaptation”. The happiness we feel after a particular activity or event diminishes each time it’s repeated. It’s likely this phenomenon is “adaptive” – we’ve evolved to react that way because it increases our ability to survive and reproduce; it keeps us striving.

But the researchers find that giving to others may be an exception to the rule. In two studies they found that participants’ happiness did not decline, or declined more slowly, if they repeatedly bestowed gifts on others versus repeatedly receiving those same gifts themselves.

Separate research by Dr Vera te Velde, a lecturer in economics at the University of Queensland, has found evidence for the existence of “beliefs-based altruism” – concern about other people’s emotions and other psychological experiences, beyond any material measure of their wellbeing.

This means “we don’t give gifts only because we want people to have something that they want; we also give gifts because we want them to feel cared about, experience joy or a pleasant surprise when receiving it. Or to prevent them from feeling disappointed if we fail to give anything,” she says.

This kind of altruism can apply in many other situations. “When girl guides come to our doors to sell cookies, we buy them not only to support the group and because we like cookies, but also because we want the girls to feel successful and valued,” she says.

But how can we be sure that a pure concern for others’ feelings is the motivation for these behaviours, instead of – or maybe, as well as – concern about our own reputations? After all, I may not only want girl guides to feel good, I may also want to be known as someone who supports them.

To help answer this question Velde experimented with a sharing game. One person is asked to share $10 with another person. But the bank handling the transfer occasionally makes a mistake and transfers exactly $1 to the other person. So if that person receives $1, they don’t know if it’s a bank mistake or the first person’s selfishness.

Asked whether they thought the recipients would prefer to know about giver’s true intentions, many participants thought they would. Even so, when they played the game themselves, the participants were more likely to give either exactly $1 (thereby hiding their selfishness) or exactly $5 (thereby revealing themselves to be perfectly fair).

But get this: even the people who tried to hide their selfishness were demonstrating their concern about the emotions of the other person. Economics makes a lot more sense with a bit of psychology thrown in.

What motivates decent bankers to rip off their customers

Amid all the reluctant truth-telling at the banking royal commission, one big lie has yet to be apprehended: shame-faced witnesses keep admitting they put their shareholders’ interests ahead of their customers’. Don’t believe it.

From the chief executives and company directors to those middling managers who seem to be the main ones being sent into the firing line, it’s not the shareholders’ pockets they’ve been so keen to line, it’s their own.

They’ve been jumping whatever hurdles they’ve had to clear to get the bonuses they were promised. Why would you rip off old people’s life savings for any lesser reason?

It’s a safe bet that everyone from the very top to well down has been “incentivised” with performance targets and bonuses. I reckon only the lowly would be lumbered with key performance indicators unattached to extra moolah.

It’s hard to imagine how so many seemingly ordinary, decent Australians were led to do so many unethical, dishonest, even illegal things for so many years without them convincing themselves it was normal bankerly behaviour – “everyone’s doing it; I don’t want to miss out” – and that by achieving the targets their bosses had set them, they were being diligent and loyal employees, worthy of reward.

But though the financial services industry must surely be the most egregious instance of the misuse of performance indicators and performance pay, let’s not forget “metrics” is one of the great curses of modern times.

It’s about computers, of course. They’ve made it much easier and cheaper to measure, record and look up the various dimensions of a big organisation’s performance, as well as generating far more measurable data about many aspects of that performance.

Which gave someone the bright idea that all this measurement could be used as an easy and simple way to manage big organisations and motivate people to improve their performance.

Setting people targets for particular aspects of their performance does that. And attaching the achievement of those targets to monetary rewards hyper-charges them.

Hence all the slogans about “what gets measured gets done” and “anything that can be measured can be improved”.

Thus have metrics been used to attempt to improve the performance of almost all the major institutions in our lives: not just big businesses, but primary, secondary and higher education, medicine and hospitals, policing, the public service – the Tax Office and Centrelink, for instance.

Trouble is, whenever we discover new and exciting ways of minimising mental effort, we run a great risk that, while we’re giving our brains a breather, the show will run off the rails in some unexpected way.

It took a while for someone to come up with the slogan antidote: “Not everything that can be counted counts, and not everything that counts can be counted”. Not everything that’s important is measurable, and much that is measurable is unimportant.

Trust, which the bankers had a lot of, is hugely valuable but hard to measure. They failed to notice the way their sharp practice – their attempt to “monetise” that trust – was eroding it.

And now they are reaping a whirlwind no KPI warned them was coming. If you work in financial services, don’t try measuring “esteem” or “reputation” any time soon.

I’ve long harboured doubts about the metric mania, but it’s all laid out in a new book, The Tyranny of Metrics, by Jerry Muller, a history professor at the Catholic University of America, in Washington DC.

Muller says we’ve been gripped by “metric fixation” which is “the seemingly irresistible pressure to measure performance, to publicise it, and to reward it, often in the face of evidence that this just doesn’t work very well”.

The glaring weakness of metrics and KPIs is how easily they can be fudged. Since most jobs are multifaceted, and you can’t slap a KPI on every facet, the simplest and least dishonest way to fudge is concentrate on those aspects of the job covered by a KPI, at the expense of those that aren’t.

Everyone from the chief executive to the lowliest clerk understands this. So why does the practice persist? Because bosses are just as busy fudging their targets as their underlings are. So long as your fudging helps your boss with their fudge, what’s the problem?

Schools fudge their performance on standardised tests by “teaching to the test” or even inviting poor performers to stay home on test day. Police services improve their serious crime clear-up rates by classing more crimes as less serious, or failing to record every crime reported to them.

Hospitals improve their performance by declining to admit people with complicated problems; surgeons improve their performance rates by refusing to treat tricky cases. Sometimes this means patients with big problems suffer delays in treatment, and maybe die. But this doesn’t show in the indicator.

Muller notes the obsession with measurement can get everyone focused on unimportant things that seem easy to measure and away from important things that can’t be measured. It can divert resources away from frontline producers towards managers, administrators and data handlers.

Worse, using money to motivate people tends to crowd out intrinsic motivation: taking a pride in doing your job well and giving customers or taxpayers value for money. It can distort an organisation’s goals and stifle creativity.

Measurement’s fine, so long as it’s used as an aid to human judgment, not a substitute for it.

Unions play their cards wrong in hopes for higher pay

You don't need to read much between the lines to suspect that Reserve Bank governor Dr Philip Lowe and his offsiders think the workers and their unions should be pushing harder for a decent pay rise.

Why else would he volunteer the opinion, in his testimony to a parliamentary committee on Friday, that average wage growth of 3.5 per cent a year would be no threat to the Reserve's inflation target?

This while employers are crying poor and Scott Morrison makes the extraordinary claim that big business needs a cut in company tax so it can afford to pay higher wages.

Why should Lowe care about how well the workers are doing? Because, as one of his assistant governors, Dr Luci Ellis, pointed out last week, our economic worries are shared by most of the other rich economies, except in one vital respect: they have reasonably strong growth in consumer spending, but we don't.

What's making our households especially parsimonious? No prize for remembering our world-beating level of household debt. Trouble is, consumer spending accounts for well over half the demand that drives economic growth.

Our economy won't be sparking on all four cylinders until consumption spending recovers, and that's not likely until our households return to annual wage growth that's a percent or more higher than inflation. That's why Lowe's encouraging workers to think bigger in their wage demands.

Even so, his proposed pay norm of 3.5 per cent, errs on the cautious side. That figure comes from 2.5 percentage points for the mid-point of the inflation target, plus 1 percentage point for the medium-term trend rate of improvement in the productivity of labour.

But 4 per cent a year would be nearer the mark because the trend rate of productivity improvement is nearer 1.5 per cent a year.

Even so, Lowe is acknowledging a point employers and conservative politicians have obfuscated for decades: national productivity improvement justifies pay rises above inflation, not just nominal increases to compensate for inflation (as is happening at present).

Lowe's concern that the present annual wage growth of about 2 per cent not be accepted as "the new norm" is an important point from behavioural economics: rather than calculate the appropriate size of pay rises based on the specific circumstances of the particular enterprise, as textbooks assume, there's a strong tendency for bargainers to settle for whatever rise most other people are getting.

That is, there's more psychology – more "animal spirits", as Lowe likes to say; more herd behaviour – and less objective assessment, in wage fixing than it suits many employers and mainstream economists to admit.

Which implies that, if the unions would prefer a wage norm closer to 4 per cent than 2 per cent, they should be doing a better job of managing their troops' fears and expectations.

In the Reserve's search for explanations of the four-year period of weak wage growth, it puts much emphasis on increased competitive pressure, present or prospective.

But in her speech last week, Ellis qualified her reference to the more challenging "competitive landscape" by adding ". . . or at least how it is perceived". Just so. It's about perceptions of reality.

It's easier for firms worried about a future of more intense competition to take the precaution of awarding minimal wage rises if they can play on their employees' own fears about losing their jobs to Asian sweatshops or robots or the internet.

There's little sign in the figures for business profitability that most firms couldn't afford much bigger pay rises than they're granting. But it's no skin off the employers' nose if their fears of future adversity prove exaggerated. Only their workers had to pay for the excessive fearfulness.

Workers - particularly those in industries with enterprise bargaining – are meekly accepting smaller pay rises than their employers' circumstances could sustain because the union movement has done too little to counter the alarmists telling their members they've lost the power to ask for more.

They've played along with the nonsense about 40 per cent of jobs being lost to robots, and that there's nothing to stop greedy businesses from making us all members of some imaginary "gig economy".

Worse, they've exaggerated the spread of "precarious employment" and encouraged the still-speculative belief that weak wage growth is explained almost exclusively by anti-union industrial relations "reform", which has stripped workers' bargaining power to the point where the right to strike has been lost.

Presumably, their game is to advantage their Labor mates by heightening disaffection with the Turnbull government, but this is coming at the expense of the economy's recovery, not to mention workers' pay packets.

How our penchant for magic numbers gets us into trouble

A lot of the problems we cause ourselves – whether as individuals or as a community – arise from the way we've evolved to economise on thinking time by taking mental shortcuts.

We are a thinking animal, but there are two problems. First, we have to make so many thousands of decisions in the course of a day – most of them trivial, such as whether to take another sip of coffee – that there simply isn't enough time to think about more than a few of them.

Second, using our brains to think requires energy, in the form of glucose. But glucose is not in infinite supply. So we've evolved to save energy by minimising the thinking we do.

As Daniel Kahneman​ – an Israeli-American psychologist who won the Nobel prize in economics for his work with the late Amos Tversky​ on decision-making – explains in his bestselling Thinking, Fast and Slow, our brains solve these two problems by making all but the biggest, non-urgent decisions unconsciously.

This is Thinking Fast. We don't think about taking another sip of coffee, we just notice ourselves reaching for the cup.

But even when we are Thinking Slow, carefully considering a big decision – such as which house to buy, or whether to marry the person we've been seeing – we still have a tendency to save glucose by relying on what Kahneman and Tversky dubbed "heuristics" – mental shortcuts.

They stressed that our use of such shortcuts is, in general, a good thing. We fall into the habit of jumping to certain conclusions because, most of the time, they give us the right answer while saving brain fuel.

But they don't give us the right answer in every circumstance, and it's the classes of cases where they lead us astray that are most interesting and worth knowing about.

Kahneman and Tversky kicked off a small industry of psychologists thinking up different potentially misleading mental shortcuts and giving them fancy names.

I have a couple of my own I'd like to add to the list.

I call the first one "box labelling" – saving thinking time by consigning things or people to boxes with particular labels.

For example: "I regularly vote Labor/Liberal, therefore I don't have to think about the rights and wrongs of all the policy issues the pollies argue over, but can get my opinion just by checking which side my party's on."

You can see how common this is if you look those media opinion polls that show you how many people support or oppose a particular policy – say, curbing negative gearing – then show you who those people would vote for in an election.

Much more often than not, people take their lead on an issue from the position their favoured party takes.

You also see it by watching what happens to the index of consumer confidence when there's a change of government. Almost all those who voted for the losing party switch from optimism to pessimism, while those who voted for the winner switch from pessimist to optimist.

My second mental shortcut is "magic numbers". Experts develop and carefully calculate some economic or financial indicator, based on various assumptions.

The indicator measures changes in something we know is important, so we get used to watching it closely for an indication of how things are going.

Trouble is, we end up putting too much reliance on the indicator, using it as a mental shortcut – a substitute for thinking hard about what's going on.

We turn it into a magic number – a single figure that tells us all we need to know. We use it to inform us about things it wasn't designed to measure.

But, above all, we forget about all the assumptions on which it's built, assumptions that can become inappropriate or misleading without us noticing. That's when our magic numbers hit us on the head.

The American economic historian Barry Eichengreen attributes part of the blame for the global financial crisis to Wall Street's excessive reliance on a financial indicator called "value at risk" or VaR.

As Wikipedia tells us, VaR "estimates how much a set of investments might lose, given normal market conditions, in a set time period such as a day. VaR is typically used by firms and regulators in the financial industry to gauge the amount of assets needed to cover possible losses."

Eichengreen tells of the banking boss who, late each afternoon, would call for the figure giving the investment bank's VaR. If it fell within a certain range, the banker would go home content. If it was outside the range, he'd stay until he'd done whatever was needed to get it back into range.

The problem was his neglect of the assumptions on which the calculation was based, in particular, "given normal market conditions". Conditions stopped being normal without him realising and – like all its competitors – his bank got into deep trouble.

But the most notorious magic number is gross domestic product, GDP. It was developed by economists after World War II to help them manage the macro economy, but has since been widely adopted as the single indicator of economic progress.

Economists know that GDP is good at what it measures, but was never designed to be a broader measure of wellbeing. This, however, doesn't stop them treating the ups and downs of GDP as the be-all and end-all of economics, as a substitute for thought.

Another word for this is "bottomlinism" – don't bother me with the details, just give me the bottom line.

But never inquiring beyond the bottom line will often end up misleading yourself or getting you into trouble. That's particularly true of people who hear the words "deficit" and "debt" and immediately assume the worst.

In business, however, the most dangerous magic numbers – the most egregious substitute for the effort of thought – are known as KPIs – key performance indicators.

Think you're pretty sharp? Try this simple quiz

It's the last (unofficial) holiday weekend of summer before the new year really gets down to business on Monday. So let's have some fun. Try yourself on this simple quiz.
Q1: Linda is 31 years old, single, outspoken and very bright. At uni, she majored in philosophy. As a student she was deeply concerned with issues of discrimination and social justice, and also participated in anti-nuclear demonstrations.
Which of these two is more likely: that Linda is a bank teller or that Linda is a bank teller and is active in the feminist movement?
If you went for a feminist bank teller - sorry, wrong.
Q2: As an investor you're trying to decide between buying shares in three listed companies when you notice that one of them's been chosen as company of the year by a business magazine. Would that make it best bet of the three?
Q3: You're trying to decide which super fund to put your savings in, so you look up the figures to see which one had the highest returns last year. Would it be the best bet?
If you answered yes to those questions you're likely to be disappointed.
Q4: The instructors of fighter pilots found that pilots who were praised when they'd flown well always performed worse the next time, whereas those who were criticised for performing badly always performed better the next time.
The instructors concluded that criticism was more effective than praise. Were they right?
If you answered yes - sorry, wrong.
Q5: You flip an unbiased coin and it comes up five heads in a row. Which is more likely from the sixth throw: heads or tails?
Q6: Which is the more likely birth order in a family of six kids: B B B G G G or G B B G B G?
In the first case the sixth throw is just as likely to be another head as a tail. In the second, the two birth orders are equally likely.
Q7: Which would you prefer, an operation with a 90 per cent success rate, or a different one with a 10 per cent failure rate?
Answer: Have another think about the question.
Apart from the investment questions (which I threw in to please the business editor) all those questions come from best-selling business writer Michael Lewis' latest book, The Undoing Project.
It's the story of two Israeli-American academic psychologists, Daniel Kahneman and Amos Tversky, who demonstrated how wide of the mark is the assumption of conventional economics that we're all "rational" - coldly logical - in the decisions we make, thus giving a huge push to the new school of behavioural economics.
A lot of their experiments involved our understanding of maths. Don't feel bad if you failed many of them. Most of us do, even people good at maths.
The moral is, however much or little people know about maths, particularly the rules of probability, we have trouble applying this to our daily lives because we let our emotions distract us.
Q1 was about the rules of probability. Linda certainly sounded like a feminist, but a lot of bank tellers aren't feminists so, statistically, there was a higher probability that she was a bank teller than a bank teller and a feminist.
All that guff about her interests at uni engaged our emotions and distracted us from the simple probabilities.
The questions about investment choices and fighter pilots were about a key statistical regularity most of us haven't heard of, called "reversion to the mean".
The performance of companies, super funds or fighter pilots in any year is a combination of skill and luck. We're always tempted to attribute good luck to high skill.
The luck factor is random, so a performance that's way above average is likely to have been assisted by luck, just as a really bad performance is likely to have been worsened by bad luck.
If good luck and bad luck average out over time, an outstandingly good performance is more likely to be followed by a performance closer to the average than by another rip-snorter. Similarly, a really bad performance is more likely to be followed by one not so bad.
Note that we're only accounting for the luck factor in performance, so a policy of always predicting reversion to the mean gives you a slight advantage in the forecasting stakes, not a sure thing.
The pilot trainers were observing reversion to the mean, but falsely attributing it to their own efforts in awarding praise or criticism.
Sadly, this has left many of the world's bosses suffering the delusion that criticism works better than praise.
The questions on coin tosses and baby order were about the "law of large numbers", which says that if events have equal probability of occurring, eventually they'll occur an equal number of times.
We all know that if you toss a coin enough times you'll get a roughly equal number of heads and tails. And we all know the numbers of boys and girls being born are almost equal.
Trouble is, you need thousands of samples to be sure of getting that result. By expecting to see equal numbers in a sample as small as six, we've turned the statisticians' law of large numbers into our own imaginary "law of small numbers".
Remember, probability theory applies to independent events, where what's gone before has no effect on what happens next.
Humans are pattern-seeking animals, but sometimes we go too far and see patterns that aren't real. Five heads in a row, or three boys followed by three girls, may look unlikely but, because the law applies only to large numbers, are perfectly consistent with a random draw.
Whether it's heads or tails, boy or girl, the safest bet remains 50/50. In the case of the five heads in a row, no one told the coin its duty was to make its sixth toss a tail.

How behavioural economics got started

One night in 1975, Richard Thaler invited a bunch of his graduate economics student mates over for dinner. While they waited for the cooking to finish he put out a bowl of cashews.

But noticing everyone was getting stuck in, he decided he'd better take them away. His mates thanked him for doing it. It was a lightbulb moment for the young economist.

Why? Because the assumptions of the conventional economics they were studying said such a thing couldn't happen.

Each of us is assumed to have complete control over our appetites and urges. We eat no more cashews than we know is good for us.

We certainly don't need some agent of the Nanny State to limit our freedom by stepping in and taking the bowl away.

Were such a thing to happen, we wouldn't be pleased. We certainly wouldn't thank the perpetrator of this intervention.

So why did it happen? Because, contrary to the conventional model, all of us have problems stopping ourselves from doing things we know we'll regret. In one part of our lives or another, we have a problem with self-control.

And we're grateful rather than resentful when someone steps in to help us with our problem.

From then on the young Thaler – obviously a bit of a rebel and troublemaker – began compiling a list of what he came to call "anomalies" – things people actually did that the conventional model assumed they didn't.

Thaler tells the story of those cashews in his latest book, Misbehaving. It's an apt title because the book charts the development of a new school of economic thought known as "behavioural economics".

Behavioural economics studies the differences between the way people in the economy actually behave and the way the model assumes they do.

In deference to academic economists' obsession with mathematics – a preoccupation that began only after World War II, led by men such as Sir John Hicks, Kenneth Arrow and Paul Samuelson – younger behavioural economists search for ways to make more realistic the assumptions on which mathematical models of the economy are built.

Thaler says behavioural economics has three essential elements: bounded rationality (see below), bounded willpower (see above) and bounded self-interest – we can be more generous to others than the model assumes.

So what are the origins of "BE"? In their book, Animal Spirits, George Akerlof and Robert Shiller argue that John Maynard Keynes was the first behavioural economist.

Thaler says Keynes was "a true forerunner of behavioural finance". (Behavioural finance is the part of behavioural economics that focuses on behaviour in financial markets.)

Keynes argued that individuals' "animal spirits" – his word for their emotional responses – played an important role in their decision making. At times this could discourage business from investing, thus strengthening the case for governments to use their budgets to stimulate the economy.

Keynes wrote his magnum opus in 1936. But Thaler takes BE's origins back to the founder of economics, Adam Smith, and the less famous of his two books, The Theory of Moral Sentiments, published in 1759.

Smith was "an early pioneer of behavioural economics" because of his detailed description of problems of self-control.

A more obvious forerunner is the American academic Herb Simon who, in 1957, coined the term "bounded rationality" and was later awarded the Nobel prize in economics for his trouble.

Bounded rationality is the idea that people's ability to make "rational" – coolly calculating – decisions is limited by the information available to them, the trickiness of the decision, the brain's inadequate processing power and the time available for thinking about it.

Many people probably assume, however, that the true originator of BE is the Princeton psychologist Daniel Kahneman who, with his late partner, Amos Tversky, began in the early 1970s identifying the many "heuristics" (mental shortcuts) and biases that cause humans' decision making to be less than rational.

Behavioural economics has long been about incorporating the insights of psychology into economics. So it was no great surprise when the psychologist Kahneman was given the economics Nobel in 2002.

Thaler moved to California in 1977 to work with Kahneman and Tversky for a year, but that was because he'd already done a lot of thinking about "anomalies". His book leaves me in little doubt that he's the economist who should get most credit for establishing BE as a respectable subject for economists to study.

Thaler began writing a column about "anomalies" from the first issue of the American Economic Association's new Journal of Economic Perspectives in 1987.

In 1991 he teamed up with Shiller (who in 2013 got the Nobel for his work in behavioural finance) to organise a semi-annual workshop on behavioural finance under the auspices of the National Bureau of Economic Research.

One breakthrough in BE came when it was demonstrated that people's mental biases were systematic – that we were, in the title of Dan Ariely's book, Predictably Irrational.

If non-rational behaviour is predictable, it can and should be incorporated into economists' models.

And if people make predictable mistakes when buying shares and so forth, there ought to be scope for other investors to make a buck by betting against them.

Little wonder behavioural finance quickly gained a following in financial circles.

In economics, however, it's said that new ideas gain ascendancy "one funeral at a time". Oldies have a vested interest in preserving the received wisdom, but young academics are attracted to new and interesting ideas that seem to better explain the world.

Thaler's best-selling book with Cass Sunstein, Nudge, showing how governments can nudge people towards making more sensible decisions, led to the setting up of Britain's Behavioural Insights Team and copycat outfits in many countries, including Oz.

These days, BE is offered in most undergraduate university courses. So behavioural economics is now firmly rooted and can only grow in its influence on economists' thinking.

The best economists know the market is flawed

As almost every economist will tell you, the market economy – the capitalist system, if you prefer – works in a way that's almost miraculous. All of us owe our present prosperity to it.

Think of it: each of us in the marketplace – whether we're buyers or sellers, consumers or producers – is acting in our own interests. A butcher sells us meat not to do us a favour, but to make a living. We, in turn, buy our meat from him not to do him a favour, but to feed ourselves.

That's how market economies work: everyone seeks to advance their own interests without regard for the interests of others. It ought to produce chaos, but doesn't.

Somehow the market's "invisible hand" has taken all our selfish motivations and transformed them into an orderly, smooth-working system from which we all benefit. The butcher makes her living; we get the meat we need.

Heard that story before? It contains much truth. But not the whole truth. Business people, economists and politicians often use it to imply that everything that happens in a market economy is wonderful.

Or they use it to argue that the best way to get the most out of a market economy is to keep it as free as possible from intervention by meddling governments. We should keep government as small as possible and taxes as low as possible.

But market economies aren't always orderly and smooth working. They move through cycles of wonderful booms but terrible busts.

And it's not true that "all things work together for good". A fair bit of the self-seeking behaviour of producers isn't miraculously converted into consumer benefit.

I've been reading a book called Phishing for Phools, a play on the online practice of phishing: posing as a reputable company to trick people into disclosing personal information.

The authors say that "if business people behave in the purely selfish and self-serving way that economic theory assumes, our free-market system tends to spawn manipulation and deception.

"The problem is not that there are a lot of evil people. Most people play by the rules and are just trying to make a good living. But, inevitably, the competitive pressures for businessmen to practice deception and manipulation in free markets lead us to buy, and pay too much for, products that we do not need; to work at jobs that give us little purpose; and to wonder why our lives have gone amiss."

You're probably not terribly surprised to read such sentiments. The surprise is that they're being expressed by two economics professors, George Akerlof, of the University of California, Berkeley (and husband of the chair of the US Federal Reserve), and Robert Shiller, of Yale University, who are held in such high regard by their peers that they're separate winners of the Nobel prize in economics.

They say they wrote the book as admirers of the free-market system, but hoping to help people better find their way in it.

If competition between business people too often induces them to manipulate their customers, why do we so often fall for it? Because though economists assume we always act in our own best interest, psychologists have convincingly demonstrated that people frequently make decisions that aren't in their best interest.

The market often gives people what they think they want rather what they really want. The authors point to common market outcomes that can't possibly be wanted.

One is a high degree of personal financial insecurity. "Most adults, even in rich countries, go to bed at night worried about how to pay the bills," they say. Too many people find it too hard to always resist the blandishments of marketers so as to live easily within their budgets.

It was all the phishing for phools in financial markets – people were sold houses they couldn't afford; people sold securities that weren't as safe as they were professed to be – that led to the global financial crisis and the Great Recession that hurt so many.

Then there's the way processed foods from supermarkets and food sold by fast-food outlets and restaurants come laced with the health-harming things they know we love: salt, fat and sugar.

The authors say a great deal of phishing comes from supplying us with misleading or erroneous information. "There are two ways to make money. The first is the honest way: give customers something they value at $1; produce it for less.

"But another way is to give customers false information or induce them to reach a false conclusion so they think that what they are getting for $1 is worth that, even though it is actually worth less."

Another class of phishing involves playing psychological tricks on us. According to the research of the American psychologist Robert Cialdini, we're phishable because we want to reciprocate gifts and favours, because we want to be nice to people we like, because we don't want to disobey authority, because we tend to follow others in deciding how to behave, because we want our decisions to be internally consistent, and because we are averse to taking losses.

There's no better way to organise an economy than by using markets. But market outcomes are often far from perfect and we need governments to regulate them as well as offset some of their worst effects.

Competition does have its drawbacks

Competition is billed by economists as a wonderful thing, the invisible restrainer of a capitalist economy and essential to ensuring consumers get a good deal.

But many economists aren't as conscious as they should be that competition has costs as well as benefits.

It's true, of course, that monopoly is usually a terrible thing, allowing arrogant, inflexible behaviour on the part of producers, with little pressure on them to keep prices down or to provide much choice. Dealing with government departments shows you what monopolies are like.

Economists tend to assume the more competition the better and that customers can never get too much choice. But this shows how – despite their loud protestations to the contrary – their thinking is excessively influenced by their most basic, least realistic model of "perfect competition".

Psychological experiments show that when shoppers face too much choice, they tend to avoid making a decision. That's because the information they need to make informed choices isn't freely available and because the human mind hasn't evolved to be good at choosing between more than two items with differing characteristics.

Many real-world markets are characterised by oligopoly: a few large firms accounting for most of the sales. Oligopolies make economic sense because they're needed to fully exploit economies of scale (which are assumed away under perfect competition). So, in reality, competition and scale economies are in conflict.

In oligopolies and even in markets with a relatively large number of producers, competition is blunted by product differentiation, much of which is cosmetic. As with most advertising, product differentiation is intended to induce consumers to make decisions on an emotional rather than rational basis.

Phoney differentiation is also intended to frustrate rational comparison. It's not by chance that it's almost impossible to compare mobile phone contracts.

When economists speak of competition, they're usually thinking of competition on price. But though oligopolists watch their competitors like hawks, they much prefer to avoid price competition, competing rather via advertising, marketing, packaging and other differentiation.

Mackay's Law of competition states that the key to competition is to focus on the customer, not your competitor. But this is what oligopolists don't do.

In the real world – including the media – competitor-oriented competition is rife. This robs customers of genuine choice. It's a form of risk aversion: if I do the same as my competitor, I minimise the risk of him beating me.

It's what, in Harold Hotelling's classic example, prompts two ice-cream sellers to be back-to-back in the middle of the beach, regardless of whether some other positioning would serve customers better. It explains why business economists' forecasts tend to cluster, usually around the official forecast.

In his book The Darwin Economy, Robert Frank, of Cornell University, argues that lefties tend to see inadequate competition as the most prevalent form of market failure, whereas it's actually "collective action problems".

A collective action problem arises when the players in a market realise they're doing something mutually destructive, but no one's game to stop doing it for fear of being creamed by their competitors.

Usually in commercial markets the only answer is for the government to intervene and impose a solution on all players; for which they're grateful.

However, that's no help to our political parties, which have got themselves locked in a game of ever-declining standards of behaviour they don't know how to escape from. It's collective action problems that make it so easy for the politicians to manipulate the media.

The advocates of federalism believe it's good to have the states free to be different and competing against each other. In reality, the competition is mainly negative. The states compete to attract foreign investors with special tax concessions and the foreigners play them off against each other.

In the early 1970s, the McMahon government transferred its payroll tax to the states to give them the "growth tax" they needed to cover their growing spending. In the decades since then, they've done little but compete with the others by raising their tax-free thresholds and cutting their rates.

The huge increase in federal grants to private schools over recent decades was justified as increasing parents' choice and imposing competitive pressure on public schools. There's little evidence it's worked, nor much even that it's held down private school fees.

Similarly, Julia Gillard's My School website, with all its information about the academic performance of particular schools, intended to increase competition between them, has failed to produce any increase in the proportion of students achieving national minimum standards in reading, writing and numeracy over the five years to 2014.

Depending on circumstances, competition can make things better or worse – or little different.

KPIs a dumb way to encourage good performance

You've been doing good work lately, and the boss is thinking of acknowledging your contribution. How would you like to be thanked? With a bonus, or with some kind of award?

If you want the money rather than the glory you'd be in good company. That's how most bosses want their own good work rewarded (and arrange their compensation package accordingly).

And it's how almost every economist would advise your boss to reward you. But don't be so sure it is what you really want, what would yield you the most lasting satisfaction.

One of the big issues in business - particularly big business - is how best to motivate and reward good performance.

Since economics is defined by some economists as the study of incentives, you'd think this was right up their alley. But economics is so focused on monetary incentives that most economists tend to assume away any non-monetary motivations.

They'll tell you the best way to "incentivate" people is performance pay: promise them a particular bonus provided they meet the targets you've set on a few "key performance indicators". Apart from that, just pay the good performers more than the poor performers.

But there's a lot more to human motivation than that and, fortunately, some economists are starting to take a less narrow approach to the topic. One is Professor Bruno Frey, of the University of Zurich.

In a paper with Jana Gallus he discusses The Power of Awards and puts them into the context of other forms of reward. Money is obviously the most common form and it has the great advantage of "fungibility" - you can spend it however you choose. And it can be applied marginally - do a bit more, get a bit more; do a lot more, get a lot more.

A second form of reward is non-monetary, but still a material award: fringe benefits, such as a company car or a particularly attractive office. These have the disadvantage of lacking fungibility (I might prefer money to a car), but usually carry a tax advantage. Even a corner office brings me status that isn't taxed.

Money and cars are "extrinsic motivators" - you do a good job as a means to getting what you really want. The message is slow to get through to business, but among behavioural economists there's now more interest encouraging "intrinsic" motivation - you do a good job because it makes you feel good. You're good at what you do and you enjoy doing it. You like knowing you've done a lot to help your customers.

The way to foster intrinsic motivation is to treat your staff well, of course, but the key is to give people discretion in the way they do their jobs. It's the opposite of trying to tie them up with KPIs.

Frey and Gallus say awards fall somewhere between these two approaches - they're extrinsic, but often not material. They include titles, prizes, orders, medals and other decorations. They are ubiquitous in society, if not business.

They're widely used in public life (various ranks of the Order of Australia), the entertainment industry (Oscars, Grammys, Logies), journalism (Walkleys, journalist of the year), sport (Brownlow medal, Dally M medal, Olympic medals), academia (fellowships of prestigious scholarly bodies, honorary doctorates, Nobel prizes) and the Catholic Church (canonisation and papal knighthoods).

The point is that the many advantages of awards suggest they should be used more in the business world.

For one thing, they're cheap to confer, but highly valued by the recipient because of the recognition as well as status they bring - provided you don't give out too many, make them too easy to attain or award them to the clearly undeserving.

More significantly, they avoid the drawback of KPIs and performance pay. The authors say such inducements are appropriate only if the performance criteria are precisely determined and measured. But for many complex activities, this is  not possible.

If it isn't, KPIs encourage what social scientists euphemistically call "strategic behaviour" - gaming the system by performing well only on those dimensions that are measured.

Monetary rewards may reduce work effort by crowding out intrinsic motivation, training people to try hard only when there's money to be gained. Why spend time helping a colleague when this might help them achieve their KPIs at the expense of your own?

The authors say monetary rewards don't induce employee loyalty. They're a strictly commercial transaction. But awards do encourage loyalty, as well as intrinsic motivation.

Overpaid chief executives shouldn't assume their workers are as materialistic as they are, nor should they imagine their firm would do better if their workers' materialistic tendencies were heightened.

Behavioural economics makes more sense to regulators

Pssst ... have you heard about this great new investment product called hybrid securities? They're terrific. Rather than having to choose between high-reward, high-risk shares and low-risk, low-reward bonds and other debt securities, hybrids give you the best of both worlds: high reward, low risk.

At least, that's what I think. And it's probably what the outfit that sold me the hybrids wanted me to think. But it's certainly not what the Australian Securities and Investments Commission wants people to think.

It regards hybrid securities as highly complex, tricky investments. They often promise high yields and are issued by well-known companies with trusted brands, but "investors need to very carefully consider the features and risks before investing".

So keen is the commission to make sure it's getting the message through to potential investors that it did something unusual: it resorted to the behavioural economists – those who, rather than assuming everyone always acts rationally, use psychology to discover how real people make decisions – to help it understand what it is that attracts people to hybrids.

It commissioned the Queensland behavioural economics group at the Queensland University of Technology Business School to conduct some experiments. The group assembled a lot of business-school uni students and gave each of them 100 units to be notional invested in a portfolio of bonds, hybrids and shares, getting them to take it seriously by promising to let them keep any profit they made.

First, however, it asked each student a bunch of questions designed to establish whether their decision-making was influenced any of a range of "cognitive biases" rather than solely rational consideration of the options.

Investors are known to be commonly affected by such "heuristics" (mental shortcuts) as the availability bias, representativeness bias, framing bias, recency bias, overconfidence, illusion of control, competence bias, ambiguity aversion and mental accounting.

So now, gentle reader, it's time for me to ask you some strange questions on this long weekend.

Give me high and low estimates for the average weight of an adult male sperm whale (the largest of the toothed whales) in tonnes. Choose numbers far enough apart to be 90 per cent certain that the true answer lies somewhere between.

Don't like that one? Try this: give me high and low estimates of the distance to the moon in kilometres. Choose numbers far enough apart to be certain that the true answer lies somewhere between.

Now something more personal. When you buy a Lotto ticket do you feel more encouraged regarding your chances if you choose the number yourself rather than using a computer-generated number?

Answer: (a) I'm more likely to win if I control the numbers picked, or (b) it makes no difference to me how the numbers are chosen.

Huh? What's all this about? Extensive testing has allowed psychologists to use people's answers to the first two questions to determine whether they suffer from overconfidence. (If you must know, such whales weigh about 40 tonnes and the moon is 384,400 kilometres away.)

Plenty of investors are overconfident in the sense that they have unwarranted faith in their own intuitive reasoning, judgments and cognitive abilities. Their ability to sell up just before the boom turns to bust, for instance.

Can you guess what the Lotto question was intended to discover? It makes no difference to your (tiny) odds of winning Lotto whether you or a computer picks your numbers.

If you imagine it does, you're suffering from what psychologists call the "illusion of control" – the belief you can control, or at least influence future outcomes when, in fact, you can't.

The illusion of control has been found to contribute to the overconfidence bias. And it's a lot more common than you may think. It is, for instance, the reason people keep asking economists for their forecasts about the economy even though they know economists are hopeless forecasters. We like to delude ourselves we can control the future.

Anyway, the Queensland behavioural economists – Anup Basu, Uwe Dulleck, Yola Engler and Markus Schaffner – found from their experiment that students who were more overconfident and suffered from the illusion of control were more inclined than others to invest in hybrid securities.

With better information about what it is that attracts some investors to buy hybrids, the commission should be able craft more effective warnings to people who need to think a lot more carefully before they leap in.

Of course, it also helps to know how to word your warnings. A growing number of government regulatory bodies around the word have found that different ways of writing a letter can have a surprising effect on the way people respond to it – whether they ignore it or act on it.

The commission asked the Queensland behavioural economics group to suggest ways of improving its letters to the directors of companies in liquidation, reminding them of their legal duty to co-operate with the liquidator in handing over the company's books and providing any other information.

Again the group conducted a laboratory experiment. Such experiments, using uni students, have their disadvantages, but they also have the advantage of giving researchers greater ability to control the many factors that could influence the decisions you're studying.

The experimenters recommended that the commission proceed to a randomised controlled trial where some directors were sent the present letter, while others were sent one of four different letters: one where the order of the points was reverse to make them easier to remember, one including a "social norm" noting that about 75 per cent of directors comply, one that allows directors to make active decisions that involve them in the process, and one that appeals to the good intentions most directors have.

At least some of those changes are likely to significantly improve directors' compliance. Practical regulators are getting much more useful advice from the behavioural brand of economists.

Science runs ahead of economists' model

The failings of economists - the bum forecasts and less-than-wise advice they give us about the choices we face - can usually be traced back to the limitations of the basic model that tends to dominate the way they think, the neo-classical model.

The thinking of economists began to ossify in the second half of the 19th century, at a time when the science of psychology was in its infancy. The model was thus consolidated at a time when our understanding of human behaviour was quite primitive.

Unfortunately, the past century of progress in psychology has revealed just how far astray are many of the economic model's assumptions about how humans tick. Although a minority of economists - "behavioural economists" - have sought to incorporate these findings into their thinking, the majority have ploughed on regardless. It keeps the maths simpler.

The model is often criticised, not least by me, for its key assumption that we are always "rational" - carefully calculating and self-interested - and never instinctive or emotional in the decisions we make, but there's another assumption that's equally unrealistic and likely to lead to wrong predictions about how we'll behave.

It's that consumers and businesses always act as isolated individuals in making their decisions, uninfluenced by the decisions those around them are making, except to the extent that the combined behaviour of others affects the prices the individual faces. In other words, the model's "unit of analysis" is the individual - the "representative consumer" or "representative firm".

In truth, humans are highly social animals and our behaviour is hugely influenced by those around us. We evolved to live in small groups, which has left us with a powerful - if often unconscious - motivation to fit in with the group and avoid being ostracised.

We feel most comfortable when we're doing what everyone else is doing; we feel distinctly uncomfortable when we're doing the opposite to everyone else. We feel great loyalty to the groups we belong to, and rivalry and suspicion towards groups we don't belong to.

This means humans - "economic agents" as economists say - are prone to herd behaviour. At the most innocuous level, this makes us heavily influenced by fashion. We like to wear what others are wearing, read what others are reading and watch the movies and TV shows that others are watching.

It's remarkable that the business world could be so conscious of the need to accommodate and, indeed, exploit our susceptibility to fashion while the economists seek to analyse our behaviour using a model that assumes it away.

More significantly, our tendency to herd behaviour affects the behaviour of markets - particularly financial markets - in ways that, though we've seen it happen many times before, almost invariably catch economists unawares.

It's our propensity for "group-think" that does most to explain booms and busts in the sharemarket, but also the upswings and downswings in the economy. We swing from overly optimistic to overly pessimistic, then back again, and we tend to all do it together.

A separate aspect of the model's exclusive focus on the individual is its overemphasis on competition and underemphasis on co-operation. It's actually the human animal's unmatched ability to co-operate in solving problems that has given our species its mastery over the planet.

Human behaviour is composed of competition and co-operation. We form co-operative groups so as to enhance their ability to compete with other groups. But the economists' model captures only one dimension of the process.

The classic example of group co-operation to facilitate competition is, of course, that bedrock of modern economies, the company. Companies - often very large, multinational companies - dominate our economy, but the model tells us nothing about what goes on inside them and economists don't have much to tell us about how the existence of big companies affects the behaviour of markets.

The final and perhaps most important twist that the economic model's focus on individuals imposes on economists' thinking is an inbuilt bias against intervention in markets by co-operation at its highest level, government.

The market of individual consumers and individual (tiny) firms is assumed to be self-sufficient and self-correcting, thus making intervention by government something alien and more likely to make things worse than better.

The reality, of course, is that governments not only need to "hold the ring" - provide the protection of property rights and legal enforcement of contracts - they also need to impose rules that protect the market, and the rest of us, from the consequences of its own herd-driven excesses.

How mental biases expose us to exploitation

So, you're a regular reader of the business pages and you reckon you're smarter than the average bear when it comes to financial matters. Well, here are some common "biases" to which people fall victim when making decisions about financial products. See if you can put hand on heart and swear you've never made any of these mistakes. If you can, you're a lot smarter than me.

Have you ever overspent on your credit card, or paid off less of it than you know you should? And if you pass that one, try this one: are you confident you're saving enough to ensure your retirement is as comfortable as you'd like it to be?

If you fall short on any of those, you've been affect by what psychologists call "present bias" and behavioural economists call "time-inconsistent preferences" (so in the competition to make your discipline sound smarter than it is, the economists win).

People often succumb to the urge for immediate gratification, thinking too little about the problems this will create for them down the track. It's natural - economists would say "rational" - to value the present more highly than the future. But if you go too far in that direction and end up regretting the choices you made, you've overvalued the present and undervalued the future, making your preferences inconsistent over time.

Most of us have a self-control problem in some field or other. People who are overconfident about their ability to control themselves in the future - to, say, manage heavy repayments - will make their lives more of a pain than they need to be.

Those who are more realistic often use "commitment devices" to impose self-control on themselves. The most extreme example is to cut up your credit card. Compulsory superannuation contributions for employees are a kind of government-imposed commitment device to help us save for retirement - which may be why so few people object.

Businesses exploit our self-control problems by, say, designing a gym subscription that seems cheap, but only if we keep using it for the length of the contract. Or by starting a credit card or home loan with a low interest rate (known in the trade as a "teaser" rate) but then jumping to an overly high rate.

Have you ever delayed moving to a better bank account, or putting some of your savings in a term deposit paying a higher interest rate? The experts call this "procrastination" (now that's a surprise) and class it as a version of present bias.

Examples are legion: deciding to cancel something but not getting around to it, not checking to see if the accounts and the loans and phone contracts you have are still the best available, or not putting much work into searching for the best deal in the first place.

This, too, leaves you open to exploitation by businesses. Some offer a "free trial" while knowing few people will cancel the deal when the paying period begins. Even requiring cancellation by post exploits our inertia.

Have you ever driven a hard bargain to buy a new car, but then gone overboard buying extras like rust-proofing, window-tinting or an improved security system? Have you ever bought a new TV or computer, then been sold extended warranty insurance?

Have you ever hung on to shares now worth less than you paid for them, hoping they will come good and you won't have to accept you made a bad decision to buy them?

If so, you've fallen victim to the biases of "reference dependence" in the first case and "loss aversion" in the second.

It's virtually impossible to look at something and decide what you think about it without consciously or unconsciously comparing it with something else. When buying a car, we compare and contrast all the ones we could buy. Failing that, we compare the one we're thinking of buying with our old one. If we don't have an old car to compare with, we compare having one with going by bus.

Comparisons are almost unavoidable. But we're so dependent on having something else to compare with - use as a point of reference - that if a sensible comparison isn't available we'll use one that makes no sense at all.

An old experiment asks people to estimate how many African countries are members of the United Nations. Most people have no idea. But if, before or while asking the question I mention 60, many people will seize on that number. Do I reckon the number of countries is more or less than 60? How much more, or how much less? That's an easier question to answer.

This way of making decisions is known as "anchor and adjust" and all of us use it all the time, consciously and unconsciously. Trouble is, 60 was a number plucked from the air. Experiments show that if you mention 100 rather than 60 before asking the question you get higher answers.

Point is that our reference dependence makes us easy meat for clever salespeople. We go overboard buying extras for our new car because they all seem so cheap relative to the huge sum we've just forked out to buy the car.

Likewise with extended warranties, which are notoriously overpriced for what little you get back. Anyone wanting to buy "peace of mind" is usually overcharged.

It's an empirical fact that most of us hate making losses much more than we love making gains. By about two to one, they say.

This explains why we do silly things like hanging on to dud shares we should sell - and then should put the proceeds into something with better prospects of gain.

These examples come from a report on behavioural economics prepared by Britain's new Financial Conduct Authority, which has been charged with finding ways to prevent businesses taking advantage of our lack of rational thinking. Good idea.
