Who pays for Google and Facebook's free lunch?

There may be banks that are too big to be allowed to fail, but don’t fear that the behemoths of the digital revolution are too big to be regulated. It won’t be long before Google and Facebook cease to be laws unto themselves.

It’s the old story: the lawmakers always take a while to catch up with the innovators. But there are growing signs that governments around the developed world – particularly in Europe and Britain - are closing in on the digital giants.

And here in Australia, the Australian Competition and Consumer Commission is busy with the world’s most wide-ranging inquiry so far, which will report to the newly elected federal government in June. The commission’s boss, Rod Sims, gave a speech about it a few weeks ago, and another this week.

Sims says the commission’s purpose is “making markets work” by promoting competition and achieving well-informed consumers, so as to deliver good outcomes for consumers and the economy.

With this inquiry into the operations of “digital platforms”, he acknowledges that they have brought huge benefits to both our lives as individuals and our society more broadly.

“They are rightly regarded as impressive and successful, and very focused, commercial businesses. Google and Facebook are rapidly transforming the way consumers communicate, access news, and view advertising,” Sims says.

Each month, he says, about 19 million Australians use Google to search the internet, 17 million access Facebook, 17 million watch content on YouTube (owned by Google), and 11 million double tap on Instagram (owned by Facebook, along with WhatsApp).

The inquiry has satisfied itself that this huge size gives the two companies considerable “market power” – ability to influence the prices charged in certain markets.

“However,” Sims says, “being big is not a sin. Australian competition law does not prohibit a business from possessing substantial market power or using its efficiencies or skills to outperform its rivals.”

But the dominance of Google and Facebook does mean their behaviour should be scrutinised to see if it is harming competition or consumers.

To this end, the inquiry is focused on three potential areas of harm. First, the well-publicised issues of privacy and the collection and sale of users’ data.

Second, the digital platforms’ role in the advertising market, which is moving increasingly on line, where it’s estimated that 68¢ in every digital advertising dollar is going to Google (47¢) and Facebook (21¢).

And that’s not including classified advertising, the loss of which has been the biggest single blow to this august organ.

Sims says Google sells "search advertising", aimed at making an immediate sale, whereas Facebook sells "display advertising", aimed a making consumers aware of the product.

The pair sell ad space in their own right while also facilitating the advertising space sold by others, particularly the media companies. But the opacity of their algorithms and arrangements make it hard to know whether they favour their own ads over other people’s.

Advertisers say they don’t know what they’re paying for, where their ads are being displayed or to whom. This makes it harder for media companies to capture their share of advertising moving online.

Of course, higher costs for advertisers translate to higher prices for consumers.

Third is the digital platforms’ effect on the supply of news and journalism, the primary issue given to the inquiry.

Sims says newspapers and free-to-air radio and television are a classic example of a “two-sided market”. They serve consumers but, rather than charging them directly for the service as other businesses do, they cover their costs and profits by charging advertisers for access to their audience. (Newspaper subscriptions and cover prices accounted for only a fraction of their costs.)

Digital platforms aren’t just two-sided, they’re multi-sided. They, too, provide their services free, and charge advertisers, but also collect and sell to advertisers information about their users’ habits.

Google and Facebook select, curate, evaluate, rank, arrange and disseminate news stories. But they use stories created by others; they don’t create any news stories of their own. If they did, we could see this as no more than tough luck for the existing news media.

But as well as using the existing media’s stories to attract consumers and advertisers, about half the traffic on the Australian news media’s websites comes via Google and Facebook. So they have “a significant influence over what news and journalism Australians do and don’t see,” Sims says.

With the existing media having lost so much of its advertising revenue to the platforms, it’s not surprising they’ve had to get rid of at least a quarter of their journalists. There are a few new digital-only news outlets, but even they are having trouble making it pay.

Trouble is, news and journalism aren’t like most commercial products. They not only benefit the individual consumer, they benefit society as a whole. “Society clearly benefits from having citizens who are able to make well-informed economic, social and political decisions,” Sim says.

So news and journalism is a “public good” – if left to the profit-making private sector, not as much news and journalism will be supplied as is in the interests of society.

Public goods are usually paid for or subsidised by governments using taxpayers’ funds. If we want the benefits of Google and Facebook without losing the benefits of active, independent and challenging news media, taxpayers will have to help out.

Sims is canvassing several proposals before completing his final report. Since the former newspaper companies have realised they’ll never get much of a share of digital advertising, they’re now putting more hope in persuading their regular users to pay directly by buying subscriptions.

With the long-established attitude that everything on the internet should be free (or, at least, seem free), they’re finding it hard going.

That’s why I think Sims’ best suggestion is making personal subscriptions to the news media tax deductible, provided the outlet is bound by an acceptable code of conduct.

Top economy manager wants you to get bigger pay rises

This year more than usually, if you want straight talking about the state of the economy and its prospects, listen to the econocrats not the election-crazed politicians.

Late last week, Reserve Bank governor Dr Philip Lowe had more sensible things to say in three hours than we usually get in a month.

He was giving evidence to the House of Representatives standing committee on economics. For a start, he left little doubt about his disapproval of the way the two sides are turning the election campaign into a bidding war.

It’s clear the reason the election is being delayed until May is so Scott Morrison can use the April 2 budget to announce tax cuts in addition to the three-stage, $144 billion-over-10-years cuts he announced in last year’s budget.

He’s upping the ante not just because he’s behind in the polls, but also because Bill Shorten is promising to make the first-stage cuts about twice the size of Morrison’s. And big increases in spending on health and education.

Plus Shorten is claiming he’d have bigger budget surpluses. How? By reducing tax breaks used mainly by higher income-earners. The risk, however, is that Labor could get locked into cutting taxes and increasing spending, but not be able to get its revenue-raising measures through the Senate.

What would be worrying Lowe is that, just as we’ve come within sight of returning the budget to (tiny) surplus – but before we’ve made any progress in repaying the huge debt successive governments have racked up over the past decade – both sides have declared Mission Accomplished and started promising tax cuts galore.

Lowe said we should be running big budget surpluses and cutting back the debt as a sort of insurance policy against the next downturn in the economy – which he doesn’t see happening in the next year or two, but will happen one day.

Consider this. When the global financial crisis hit in October 2008, Lowe’s predecessor acted to protect us from the tsunami by cutting the official interest rate by 4 percentage points in about as many months.

Trouble is, we’ve since entered a low growth, low inflation world, and interest rates have remained low. The official interest rate is just 1.5 per cent. So the central bank has little scope to stimulate the economy the way it did last time.

In that case, the government should use its budget to stimulate the economy by splashing cash, spending on school playgrounds and the like.

See the problem? We won’t have much scope to do that, either, if we’ve been so busy awarding ourselves tax cuts that we’ve made little progress in reducing all the debt we’ll be starting with.

Moving on, Lowe said the economy’s two main worries were the weak growth in wages and falling house prices. But he stressed that wages and household income were far more significant than house prices.

If you were thinking it was the other way round, that may be because the media have misled you. “It’s largely the income story which doesn’t get talked about enough, because the media love talking about property prices,” he said.

Whereas household income, coming mainly from wages, used to grow by about 6 per cent a year (before allowing for inflation), in recent years it’s grown by less than 3 per cent.

Lowe didn’t say it, but what economists see as weak growth in wages, most ordinary mortals perceive as the worsening “cost of living” – which polling shows is now voters’ greatest concern.

People are having trouble balancing their own budgets, not because prices generally are soaring, but because their wages aren’t growing a per cent or two faster than prices, the way they used to.

Lowe is confident wages will gradually improve, but “if we have another five years where workers don’t get their normal share of productivity growth [that is, if wages don’t return to growing a per cent or so faster than prices each year], we’ll have all sorts of economic, social and political problems”.

Gosh. He did have some good news, however. He’s confident employment will continue growing strongly because the rate of job vacancies is higher than it’s ever been.

And whereas economists have long believed the rate of unemployment couldn’t fall below “about 5 per cent” before we started getting excessive wage settlements and rising inflation, Lowe now believes unemployment can fall further to “about 4.5 per cent” before there’s a problem. (May not sound much to you, but it gives us scope for 67,000 more jobs.)

Lowe says there’s more competition between the big banks than we’re told about. Remember a few months ago when they raised their mortgage interest rates by between 0.1 and 0.15 percentage points?

That’s what they told the media and what they wrote on their price lists. In truth, however, rates rose by only 0.03 or 0.04 points. Why? Because too many of their customers threatened to take their business elsewhere.

Finally, some free advice from the nation’s most powerful economist: “I encourage everyone who has a mortgage, if they haven’t done so recently, to go and ask their bank for a better deal. And if the bank says no, go look for another bank.”

It’s not business-bashing, it’s the public’s moment of truth

With the federal election campaign being fought over which side will do the better job of re-regulating the banks, the energy companies and business generally, big business seems to be going through the stages of grief. It’s reached denial.

According to the Australian Financial Review, the Business Council of Australia is most put out that the Morrison government has yielded to pressure from Labor and some Nationals to support a bill making it easier for smaller businesses to take legal action against big businesses.

Apparently, Scott Morrison and his lieutenants had the temerity to make the decision without giving the council an opportunity for private lobbying.

Which would have been intend to avoid “harmful unintended consequences,” including any possible drag on the economy. Of course.

Apparently, it’s just another instance of the growing level of “business bashing” in this campaign.

Sorry, guys, you’ve got to have a better argument than that. Accusing your critics of business-bashing or teacher-bashing or bank-bashing is what you say when you haven’t got a defence and are succumbing to a persecution complex.

It makes you and your mates feel better, but that’s all.

It’s a refusal to accept any responsibility for the bad performance of which people are complaining. Since it’s entirely the fault of others – usually, the government – any attempt to make me and my mates bare our share of responsibility can be explained only by ignorance and malice.

Such denial offers big business no way forward. Much better to admit there’s a fair bit of truth to the criticisms and accept that your performance will have to be a lot better.

The Business Council needs to admit to itself that this is not some passing phase of populist madness, it’s the end of the line for the “bizonomics” that micro-economic reform degenerated into – the belief that what’s good for big business is good for the economy.

The simple truth is that, when you go for years abusing your market power, the electorate eventually wakes up and hits back, threatening to toss out any government that isn’t prepared to set things to rights.

Now the scales of economic fundamentalism have fallen from our eyes, who could doubt that big businesses use their superior power – including their ability to afford the best legal advice – to unreasonably impose their will on smaller businesses, just as they impose incomprehensible and utterly non-negotiable terms and conditions on their customers. Like it or lump it.

One of the greatest weaknesses of “perfect competition” – the oversimplified model of market behaviour that permeates the thinking of economists, both consciously and unconsciously – is its implicit assumption that the parties to economic transactions are of roughly equal bargaining power.

In the era of oligopoly, however – where so many markets are dominated by four or even two huge corporations - nothing could be further from the truth.

It’s thus perfectly reasonable for governments to intervene in markets to bolster the bargaining power of the smaller and weaker parties – whether employees permitted to bargain collectively and go on strike, small businesses helped to seek legal redress from much bigger businesses, or customers protected from misleading advertising, high-pressure selling and other abuses.

It’s because economists’ thinking is so deeply infected by their model’s unrealistic assumptions that they fell for the notion that merely providing consumers with more information on labels and in “product statements” (quickly sabotaged by being turned into pages of legalese) would protect them from exploitation.

Though oligopolies have existed for decades, economists have put remarkably little effort into studying how they work and, more particularly, how they can be regulated to ensure the economies of scale they have been designed to capture are passed through to their customers.

The trouble is that oligopolies do all they can to avoid competing on price.

A part of this is offering a range of products that are almost impossible to compare with other firms’ products.

In the complex, busy world we live in, it’s utterly unrealistic to expect ordinary consumers to devote hours of precious leisure time to checking to see whether their present provider of bank accounts, credit cards, mortgages, mobile phones, electricity, gas and even superannuation is quietly taking advantage of them.

This is the case for government regulation to impose standardised comparisons and default products, statutory guarantees, legal obligations to act in the client’s best interests, and much else.

The other thing we’ve learnt in recent times – from the banking inquiry and many other examples – is that if businesses large and small are confident they won’t get caught, there’s no certainty they’ll obey the law.

We've had plenty of new jobs - for the young, not so much

You can be sure Scott Morrison and Josh Frydenberg will be boasting about this week’s job figures, which show the jobs market remaining unusually strong. But their critics know not to believe the numbers.

The Australian Bureau of Statistics’ figures for January show the seasonally adjusted rate of unemployment steady at 5 per cent – the lowest it has been since the start of the decade. The more reliable “trend” (smoothed) estimate is little different at 5.1 per cent.

Sticking with the trend figures, employment has increased by more than 295,000 people over the past year. That’s a rise of 2.4 per cent – a lot bigger than the average annual growth rate over the past 20 years of 2 per cent.

Almost three-quarters of those extra jobs were full-time. Full-time employment has been growing particularly strongly in the past few years.

Another good indicator of how well the economy is going at providing jobs for those who want to work is the employment ratio – the proportion of everyone in the population aged 15 and over who has a job. It’s steady at 62.4 per cent, the highest it’s been.

Just during January, employment increased by 24,900 to reach 12.7 million. That’s an increase of 0.2 per cent, above the monthly average growth rate over the past 20 years of 0.16 per cent.

But don’t get the idea this means all of us stayed in our jobs while another 24,900 joined us. That’s just the net increase. There was a lot more coming and going than that. Indeed, the bureau informs us that, each month, about 300,000 people leave employment and about 300,000 enter it.

Looking at that strong performance over the past couple of years, what’s not to like? With a federal election coming up, why shouldn’t Morrison and Frydenberg boast about the great job they’ve done on jobs?

Well, a lot of their critics would be happy to tell you. They know the official unemployment figures understate the true extent of joblessness.

Did you realise, for instance, that the bureau counts you as employed even if you’ve worked for as little as one hour a week?

This means that, as well as the 680,000 people counted as being unemployed, there are another 1.1 million people who are under-employed – those who have a part-time job, but want to work more hours a week than they are.

Those 1.1 million represent 8.3 per cent of the “labour force” (all those with jobs or looking for jobs). Add that 8.3 per cent to the official unemployment rate and you get a total “labour under-utilisation rate” of 13.3 per cent.

This is down from 14 per cent a year ago, with under-employment accounting for just 0.2 percentage points of the fall and unemployment accounting for the rest.

So the under-employment rate, which rose in the years after the global financial crisis, has fallen since its peak of 8.8 per cent in early 2017, but much more slowly than the fall in unemployment.

That’s the standard critique of the official story: the “true” extent of joblessness is far higher than the official unemployment rate tells us, and when you take account of widespread under-employment you see also that the rate of improvement has been a lot smaller.

What are we to make of this criticism? Well, it’s correct factually, but when you look deeper you see it goes to the other extreme of overstating the extent of the problem.

Take, for instance, the oft-repeated news that people are counted as unemployed if they work for as little as an hour a week. That’s true, but how many people do work as little as an hour?

Answer: almost no one. This week the bureau issued a special note about this matter. It says that only about 14,500 people do, out of total workforce of 12.7 million – that is, 0.1 per cent. (If you think 14,500 people is a lot, you don't realise how big our economy is.)

Make it people working up to three hours a week and you’re still only up to 100,400 people, or 0.8 per cent. In fact, about 97 per cent of workers usually work seven hours or more a week. That’s at least one full shift a week.

The point is that you have to draw the dividing line between unemployed and employed somewhere, and by adhering to the longstanding international convention of drawing it at an hour a week, we are not significantly overstating the position.

Many people assume the only good job is one that’s full-time. Wrong. Many students, parents and semi-retired people are perfectly happy working only part-time.

Further, many people assume that every part-time worker who says they’d like to work more hours is someone who’d rather have a full-time job if only they could find one. That’s wrong, too. Though many would indeed prefer a full-time job, many part-timers want to stay part-time, but wouldn’t mind working a few extra hours.

So when you take the unemployment rate (people with no job) and simply add the under-employment rate of 8.3 per cent on to it, you’re exaggerating the number of people working significantly fewer hours than they want to.

But let’s take a closer look at under-employment. As the bureau has explained, it is concentrated among the young. More than a third of the under-employed are aged 15 to 24. About 18 per cent of all workers in this age group are under-employed.

It seems clear that education-leavers have borne more than their fair share of the pain during the period of below-par growth since the global financial crisis in 2008. Many people leaving university have had to settle for a part-time job and, until quite recently, they’ve taken more months to make it into full-time employment.

The latest figures from the universities show their new graduates are now taking less time to find a decent job than they were.

But, in any case, caring about the troubles of young people is deeply unfashionable. It’s the well-off elderly we should be worrying about.

If only the Indigenous had the worries of the well-off aged

One thing I hate about elections is the way politicians on both sides seek to advance their careers by appealing to our own self-centredness. I suppose when they know how little we respect them for their principles, they think bribing us is all that’s left.

The federal election campaign hasn’t started officially, but already the one issue to arouse any passion is the spectacle of the most well-off among our retired screaming to high heaven over the proposal that, though granted the concession of paying no tax on income from superannuation, they should no longer receive tax refunds as though they were paying it.

We teach our children to respect the needs and feelings of others, and to take turns with their toys, but when it comes to politics you just get in there and fight for as much lolly as you can grab. And if my voice is louder and elbows sharper than yours, tough luck.

When someone at one of those rallies of the righteous retired had the bad manners to suggest that the saving would be used to increase spending on health and education (and increase the tax cut going to those middle-income families still required to pay tax on their incomes) they were howled down. Health and education? Don’t ask me to pay.

You gave me this unbelievably good tax deal, I paid the experts to rearrange my share portfolio so as to fully exploit it, and now you tell me you’ve discovered you can’t afford it and other people’s needs take priority. It so unfair.

Meanwhile, at the other end of the income spectrum, Scott Morrison delivered a Closing the Gap report to Parliament last Thursday. It was the 11th report since the practice began, following Kevin Rudd’s National Apology in 2008.

Morrison was the fifth prime minister to have delivered the report. The fifth obliged to admit how little progress has been made in achieving the seven targets we set ourselves.

The original targets were to halve the gap in child mortality by 2018, to have 95 per cent of all Indigenous four-year-olds enrolled in early childhood education by 2025, to close the gap in school attendance by 2018, to halve the gap in reading and numeracy by 2018, to halve the gap in year 12 attainment by 2020, to halve the gap in employment by 2018, and to close the gap in life expectancy by 2031.

As you see, four of the seven targets expired last year. None of them was achieved. They’re being replaced by updated – and more realistic – targets.

In his progress report, Morrison was able to say only that two out of the seven targets were on track to be met.

The first of these is the goal of having 95 per cent of Indigenous children in early childhood education by 2025. This was achieved in the latest figures, for 2017, with NSW, Victoria, South Australia, Western Australia and the ACT now at 95 per cent or more.

The other is halving the gap in year 12 attainment by 2020. Morrison says this is the area of biggest improvement, with the Indigenous proportion jumping by 18 percentage points since 2006.

With the key target of life expectancy, the figures show some improvement for Indigenous people from birth, but associate professor Nicholas Biddle, of the Centre for Aboriginal Economic Policy Research at the Australian National University, warns that the figures are dodgy.

So why have we been doing so badly? Biddle and a colleague argue that the original targets were so ambitious they couldn’t have been achieved without radically different policies, not the business-as-usual policies that transpired.

That’s one way to put it. It’s common for politicians to announce grand targets that make a splash on the day, without wondering too hard about how or whether their successors will achieve them. And no one was more prone to such “hubris” (Morrison’s word) than Kevin07.

A second reason, they say, is that successive governments’ policy actions haven’t always matched their stated policy goals. Their employment target, for instance, hasn’t been helped by the present government’s abolition of its key Indigenous job creation program, the community development employment project.

Then there’s the present government’s soft-target approach to limiting the growth in government spending, which has involved repeated cuts to the Indigenous affairs budget, particularly in Tony Abbott’s first budget.

The most significant Indigenous policy initiative in ages, the Northern Territory Intervention – which preceded Closing the Gap, but has been continued by governments of both colours – may have directly widened health and school attendance gaps.

As well as disempowering Aboriginal people in the territory, the immense amount of money and policy attention devoted to the Intervention “could have been better spent elsewhere”.

Third, they say, measures intended to achieve the targets have rarely been subject to careful evaluation and adjustment.

Morrison professes to have learnt these lessons. But, the authors say, if his “refreshed” approach “does not put resources – and the power to direct them – into Indigenous hands, the prospects for closing socio-economic gaps are likely to remain distant”.

Having stuffed-up deregulation, don't stuff-up re-regulation

As the banking royal commission finishes, the aged care royal commission begins investigating the mistreatment of old people by – taking a wild guess – mainly the for-profit providers. Surely it won’t be long before the politicians, responding to the public’s shock and outrage, are swearing to really toughen up the regulation of aged care facilities.

It’s not hard to see we’ve passed the point of “peak deregulation” and governments will now be busy responding to the electorate’s demands for tighter regulation of an ever-growing list of industries found to have abused the trust of economic reformers past.

But having gone for several decades under-regulating many industries and employers, there’s a high risk we’ll now swing to the opposite extreme of over-regulation. That could happen if politicians simply respond to populist pressures to wield the big stick against greedy business people.

It could happen if politicians yield to one of the great temptations of our spin-doctoring age: caring more about being seen to be acting decisively than whether those actions actually do much good.

And it could happen if our econocrats refuse to admit the shortcomings of their earlier advocacy of deregulation – including their naive confidence that the power of market forces would ensure businesses treated their customers well – and go into a sulk, washing their hands of responsibility for what happens next.

But against all those risks that, in seeking to correct the failures of the previous regime we introduce something that’s just as bad only different, there’s one cause for optimism: as the first cab off the re-regulatory rank, Commissioner Kenneth Hayne’s guiding principles for turning things around. (To be fair, those principles seem to have been influenced by Treasury’s submission to the commission.)

His first principle is that, since almost all the misconduct he uncovered was already unlawful, there’s no need for a raft of legislation to make them doubly illegal. The problem is more getting people to obey the existing law.

Blindingly obvious? Not to a politician who wants to be seen by an angry but uncomprehending public to be acting immediately and decisively. On the rare occasions when Australia is touched by a terrorist act, we see Parliament recalled to pass urgent legislation making terrorism quintuplely illegal.

Hayne’s second principle is that compliance will be increased by making the law simpler, rather than more complex, so no one can be in any doubt about what’s required of them.

The more complex and voluminous you make the law, the more scope you give well-resourced offenders to pay lawyers to find loopholes and argue the toss and string out court proceedings. In the process, increasing the cost to taxpayers of bringing them to justice, increasing the likelihood of them getting off and increasing the reluctance of the regulators to take them on in the first place.

Hayne says the whole body of law needs to be rewritten to simplify and clarify the legislators’ intentions. In the meantime, however, some changes should be made more quickly.

One is to get rid of exceptions, carve-outs and qualifications. Examples are the “grandfathering” (leaving existing arrangements unaffected by new rules) of certain commissions, and the exclusion of funeral insurance from rules affecting other insurance.

As two law professors from the University of Melbourne have pointed out, the rule of law requires like cases to be treated alike. To make exceptions you need powerful arguments – which haven’t been made.

“Instead,” they say, “exceptions and carve-outs reflect the lobbying of powerful industry groups concerned to preserve their own self-interest.” True. There’s no principle of deregulation that says it’s OK to look after your mates.

In highlighting the shortcomings of existing legislation, Hayne stressed that “where possible, conflicts of interest and conflicts between duty and interest [such as not acting in the best interests of your client] should be removed”.

But his final guiding principle is that existing laws must be enforced. “Too often, financial services entities that broke the law were not properly held to account. Misconduct will be deterred only if entities believe that misconduct will be detected, denounced and justly punished,” he said.

Just so. And it raises a mode of response to the electorate’s wider discontents, as governments set out on the path of “re-regulating” industries other than financial services: regulations may need improving, but we don’t need a lot more of them.

No, what we need a lot more of is regulators doing – and being seen to be doing – their job of enforcing existing regulations with vigour and effectiveness, and governments being unstinting in providing them with resources.

Back to the future: Keynes can lift us out of stagnation

Every so often the economies of the developed world malfunction, behaving in ways the economists’ theory says they shouldn’t. Economists fall to arguing among themselves about the causes of the breakdown and what should be done. We’re in such a period now.

It’s called “secular stagnation” and it’s characterised by weak growth – in the economy, in consumer spending, in business investment and in productivity improvement. This is accompanied by low price inflation and wage growth, and low real interest rates.

Let me warn you: the last time the advanced economies went haywire, it took the world’s economists about a decade to decide why their policies of managing the macro economy were no longer working and to reach consensus around a new policy approach.

That was in the mid-1970s, when the first OPEC oil-price shock brought to a head the problem of “stagflation” – high unemployment combined with high inflation – a problem the prevailing Keynesian orthodoxy said you couldn’t have.

The Keynesians’ “Phillips curve” said unemployment and inflation were logical opposites. If you had a lot of one, you wouldn’t have much of the other.

The developed world’s econocrats lost faith in Keynesianism and flirted with Milton Friedman’s “monetarism” – which was just a tarted-up version of the “neo-classical” orthodoxy that had prevailed until the Great Depression of the 1930s.

That was the previous time the economics profession fell to arguing among itself. Why? Because neo-classical economics said the Depression couldn’t happen, and had no solution to the slump bar the (counter-productive) notion that governments should balance their budgets.

It was John Maynard Keynes who, in his book The General Theory, published in 1936, explained what was wrong with neo-classical macro-economics, explained how the Depression had happened and advocated a solution: if the private sector wasn’t generating sufficient demand, the government should take its place by borrowing and spending.

In the period after World War II, almost all economists – and econocrats – became Keynesians. Until the advent of stagflation.

Notice a pattern? We start out with neo-classical thinking, then dump it for Keynesianism when it can’t explain the Depression. Then, when Keynesianism can’t explain stagflation, we dump it and revert to neo-classicism.

Enter Dr Mike Keating, a former top econocrat, who thinks the present crisis of stagnation means it’s time to dump neo-classicism and revert to Keynesianism.

Why do economists have rival theories and keep flipping between them? Because neither theory can explain every development in the economy, but both contain large elements of truth.

So it’s not so much a question of which theory is right, more a question of which is best at explaining and solving our present problem, as opposed to our last big problem.

I think there’s much to be said for this more eclectic, horses-for-courses approach. There’s no one right model. Rather, economists have a host of different models in their toolbox, and should pull out of the box the model that best fits the particular problem they’re dealing with.

And much is to be said for Keating’s argument that we need a different economic strategy to help us into the 21st century. Got a problem with stagnation? The tradesman you need to call is Keynes.

Although the rich economies are in a lot better shape than they were during the Depression – mainly because, in the global financial crisis of 2008, governments knew to apply Keynesian stimulus - Keating sees similarities between the two periods of economic and economists’ dysfunction.

In this context, the key difference between the rival theories is their differing approaches to supply and demand.

Neo-classical economics assumes the action is always on the supply side. Something called Say’s Law tells us supply creates its own demand, so get supply right and demand will look after itself.

The modern incarnation of this is “the three Ps”. In the end, economic growth is determined by the economy’s potential capacity to produce goods and services, and our “potential” growth rate is determined by the growth in population, participation and productivity improvement (with the last being the most important).

By contrast, Keynesianism is about fixing the problem Say’s Law says we can never have: deficient demand. Insufficient demand was what kept us trapped in the Depression. Keating argues the fundamental cause of our present stagnation is deficient demand, and the solution is to get demand moving again.

Back in the stagflation of the 1970s, however, the problem wasn’t deficient demand. It was the supply side of the economy’s inability to produce all the goods and services people were demanding, thus generating much inflation pressure.

After realising that Friedman’s targeting of the money supply didn’t work, the rich world’s eventual solution to the problem was what we in Australia called “micro-economic reform” – reduced protection and government regulation of industries, so as to increase competition within industries and spur greater productive efficiency and productivity improvement, thus increasing our rate of “potential” growth.

Keating – who, with another bloke of the same name, played a big part in making those early reforms – insists they worked well and left us with a more flexible, less inflation-prone economy. True.

By now, however, assuming you can fix a problem of deficient demand by chasing greater competition and improved productivity just shows you haven’t understood the deeper causes of the problem.

But when Keating advocates a new economic strategy of demand management, he doesn’t just mean governments borrowing and spending a lot of money now to give demand a short-term boost.

He mainly means a new kind of micro reform that, by increasing the income going to those likely to spend a higher proportion of it, and by lifting our education and training performance to help workers cope with new technology, ensures demand strengthens and stays strong in the years to come.

We could be among the world's climate change winners

In the dim distant past, politicians got themselves elected by showing us a Vision of Australia’s future that was brighter and more alluring than their opponent’s.

These days the pollies prefer a more negative approach, pointing to the daunting problems we face and warning that, in such uncertain times, switching to the other guy would be far too risky.

We’ve gone from “I’m much better than him” to “if you think I’m bad, he’d be worse”. Maybe they simply lack any vision of the future beyond advancing their own careers.

Management-types tell us we should conduct “SWOT analysis” – considering our strengths and weaknesses, opportunities and threats. But we’ve become mesmerised by the threats and incapable of seeing the opportunities. Such a pessimistic mindset is crippling us when we could be going from strength to strength.

Take climate change. It, of course, is a threat – to our climate, and hence to our comfort and our economy – but think a bit more about it and you realise that, for a country like ours, it’s also a new gravy train we could be climbing aboard.

The stumbling block is that responding to climate change requires change – and no one likes change, especially those who earn their living from the present way of doing things.

So, what more natural reaction than to resist change? Economists are always warning politicians not to try “picking winners”. In reality, they’re far more likely to resist change by spending lots of money trying to prop up losers.

Start by denying that change is necessary. Global warming isn’t happening, it’s just a conspiracy by scientists angling for more research funds.

Nothing new about heatwaves, bushfires, droughts, floods and cyclones – they’ve always existed. They’re becoming bigger and more frequent? Just your imagination.

What you’re not imagining is the ever-higher cost of electricity. But that’s just because those ideologues imposed a carbon tax and are making us subsidise renewable energy. Get rid of the taxes and subsidies and the cost falls back to what it was.

And those terrible wind turbines. They’re unnatural and unsightly, they kill rare birds and their noise endangers farmers’ health.

Renewable energy is unreliable because it depends on the wind blowing or the sun shining. You need coal for steady supply. With the greater reliance on renewables, where do you think the blackouts are coming from?

And renewable energy is so expensive. Coal-fired electricity is much cheaper. Plus, we’ve got all our chips stacked on coal. We’re world experts at open-cut coal mining. Our coal is much higher quality than most other countries'.

Coal provides jobs for 30,000 workers. There are towns desperate for jobs who’d just love another coal mine. And, of course, we’ve still got huge reserves of the stuff that’s of no value if it stays in the ground.

Some of these claims have always been untrue, some are no longer true and some are less true than they were.

Just this week, for instance, a report from the independent Grattan Institute has debunked the claim that “outages” are being caused by renewables, saying more than 97 per cent of outage hours can be traced to problems with the local poles and wires that transport power to businesses and homes.

While it’s true that power from existing coal-fired generators is dirt cheap, many of these are old and close to the end of their useful lives. They’re not being replaced by new coal generators because there’s too much risk that the demand for coal-fired power will dry up before the generators have returned the money invested in them.

The latest report from the CSIRO says the lowest-cost power from a newly built facility is now produced by solar and wind.

The cost of solar, battery storage and, to a lesser extent, wind power, has fallen dramatically over this decade, partly because of advances in technology but mainly because of economies of scale as China and many other countries jump on the bandwagon. These falls are likely to continue.

This has gone so far that the old arguments about the need for a price on carbon and subsidies for renewables are being overtaken by events.

Installation of renewable generation is proceeding apace, with all renewables’ share of generation in the national electricity market jumping from 16 per cent to 21 per cent, just over the year to December, according to Green Energy Markets.

So, as the economist Professor Frank Jotzo, of the Australian National University, has said, coal is on the way out. The only question is how soon it happens.

According to our present way of looking at it, this is disastrous news. But not if we see it as more an opportunity than a threat.

Professor Ross Garnaut, of the University of Melbourne, has said that “nowhere in the developed world are solar and wind resources together so abundant as in the west-facing coasts and peninsulas of southern Australia.

“Play our cards right, and Australia’s exceptionally rich endowment per person in renewable energy resources makes us a low-cost location for energy supply in a low-carbon world economy.

“That would make us the economically rational location within the developed world of a high proportion of energy-intensive processing and manufacturing activity.”

Politicians, economists will decide if bank misbehaviour stops

In the wake of the Hayne report on financial misconduct, many are asking whether the banks have really learned their lesson, whether their culture will change and how long it will take. Sorry, that’s just the smaller half of the problem.

You can’t answer those questions until you know whether the politicians and their economic advisers have learned their lesson and whether their culture will change.

Why? Because the game won’t change unless the banks believe it has changed, and that will depend on whether governments (of both colours) and their regulators keep saying and doing things that remind the banks and others on the financial-sector gravy train that the behaviour of the past will no longer go undetected and unpunished.

One of Commissioner Hayne’s most significant findings was that almost all the misbehaviour he uncovered was already illegal. Which raises an obvious query: in that case, why did so much of it happen?

Hayne’s answer was “greed”. That’s true enough, but doesn’t tell us much. Greed has been part of the human condition since before we descended from the trees. But greed has been channelled and held in check by other factors – particularly by social norms that disapprove of it and find ways to censure people who aggrandise themselves are the expense of others. In old times, social ostracism was enough.

So, since banks and other financial outfits haven’t always been willing to exploit their customers the way they have recent decades, the question is: what changed?

One explanation is that the economy’s become a bigger, more complex, more impersonal place, where the exploiter and the exploited don’t know each other. Where the exploitation is carried out by four of the biggest, most sprawling and intricate computer systems in the country.

Where I can spend my obscenely large pay cheque without seeing the faces of the people I’ve ripped off flashing before my eyes. Indeed, in my suburb, all of us get huge pay cheques. And I don’t feel guilty; some of them get much bigger cheques than me.

But another part of the explanation must surely be that things started changing after the triumph of “economic rationalism”, the introduction of microeconomic reform, and the deregulation of the financial sector in the second half of the 1980s.

In the highly regulated world, there was less scope and less incentive to mistreat customers. Competition was limited and there was little innovation. Deregulation was intended to spur competition between the banks and give customers a better deal.

I’m not saying bank deregulation was a bad idea. It did bring innovation (we forget that banking and bill-paying are infinitely more convenient than they were) and you no longer have to live in a good suburb to get a loan from a bank.

And the banks do compete far more fiercely than they used to. It's just that they compete not on price (as the reformers assumed they would) but on market share and which of the big four achieves the biggest profit increase.

In this they’ve behaved just as you’d expect oligopolists to behave.

In the meantime, economic rationalism sanctified greed (the “invisible hand” tells us the market leaves us better off because of the greed of the butcher and the baker) and economists invented euphemisms such as “self-interest” and “the profit motive”.

Then, after economists got the bright idea of using bonuses and share options to align management’s interests with shareholders’, big business elevated “shareholder value” to being companies' sole statutory obligation.

Now, however, when Hayne says the banks gave priority to sales and profits over their customers’ interests, everyone’s rolling around in horror.

And politicians and econocrats are feigning surprise that financial regulators, long given a nod and wink to dispense only “light” regulation of the players (and denied the funding to give them any hope of successful prosecutions), did just as they were told.

Unless the econocrats and their political masters are willing to accept the naivety that marred bank deregulation, the harm ultimately done to bank customers – ranging from petty theft to life-changing loss – and the system’s susceptibility to political corruption, the banks’ culture won’t change because the will to change it won't last.

The existing prohibitions on mistreatment of customers need to be made more effective, as proposed by Hayne but, above all, the law needs to be policed with vigour – including adequately resourced court proceedings – so the banks realise they have no choice but to change.

The economy isn’t in trouble, but let’s cut interest rates anyway

Rather than merely acknowledging that the next move in interest rates is as likely to be down as up, I think the Reserve Bank should get on with cutting them. But not for the reason you may imagine.

There are plenty of people – many of them in the media – silly enough to believe a fall in interest rates is always good, and a rise always bad. They have a mortgage-centred view of the universe.

They forget that lower rates are bad news for people living off their savings – or saving for a home deposit.

More particularly, they forget that central banks use interest rates to keep the economy on an even keel. Judged the conventional way, central banks cut interest rates when they judge the economy to be weak or weakening.

So, even for those with mortgages, a cut in rates is no reason to celebrate. They’ll be paying less interest, sure, but only because, in the econocrats’ judgement, there’s now a greater risk they’ll lose their job, be put on a short working week, or go for year or two without a pay rise.

Is that what you’re hoping for? I’m not. Nor do I think it’s our certain fate. The biggest risk we face is talking ourselves into a downturn – for no better reason than it would be something new to talk about.

Telling ourselves that a fall in house prices – something we’ve experienced many times before and lived to tell the tale – is the start of an avalanche.

Or, when Reserve Bank governor Dr Philip Lowe moves from saying the next move in rates is up, to saying the chances are evenly balanced between up and down, leaping to the conclusion he’s really saying a cut is imminent.

It isn’t. It isn’t because, as he made plain in a speech on Wednesday – and reiterated in the statement on monetary policy on Friday – he remains confident the economy has slowed a bit, but no worse. His revised forecast is for the economy to grow by an above-trend 3 per cent this year.

And a rate cut isn’t imminent because he said it wasn’t. “[The board] does not see a strong case for a near-term change in the cash rate. We are in the position of being able to maintain the current policy setting while we assess the shifts in the global economy and the strength of household spending.”

He also said that “what we are seeing looks to be a manageable adjustment in the housing market”.

So a rate cut isn’t imminent. According to Lowe, a cut would require “a sustained increase in the unemployment rate”. Which, judged by conventional standards, is good news. It means he believes the economy will continue plugging on.

But my point is different. Lowe is pursuing a conventional, business-as-usual approach to managing the economy because he assumes nothing fundamental has changed.

His conventional thinking is that it’s weak wage growth that’s driving the economy’s relative stagnation. It hasn’t occurred to him it’s the other way round: the economy’s stagnation is the cause of weak wage growth.

I think it’s clear the phenomenon of “secular (that is, long-lasting) stagnation” – exceptionally low inflation, low wage growth, low real interest rates, low business investment, low productivity improvement and low economic growth – applies to our economy as well as to the United States and the other advanced economies.

Every symptom on that list applies to us (bar the long-past mining investment boom). And stagnation isn’t a bad way to describe our position, where growth over the 10 financial years since the global financial crisis has averaged less than 2.6 per cent a year and only one year (2011-12) has been above trend.

One thing that’s become clear in America and other advanced economies is that secular stagnation – the causes of which economists are still debating – has caused conventional estimates of the NAIRU (“non-accelerating-inflation rate of unemployment” – the lowest rate to which unemployment can fall before wage and price inflation begin to worsen) to be far too high.

In those countries, unemployment has fallen well below where the NAIRU (sounds a bit like the island) was thought to be, without any sign of price inflation or excessive wage growth.

The same can be said of us. The Reserve estimates our NAIRU to be “about 5 per cent”. Our actual unemployment rate has been at 5 per cent or so for some months, while the latest reading for underlying inflation is 1.75 per cent and for the wage price index is 2.2 per cent.

So, we’re at the supposed NAIRU without the slightest sign of inflation pressure. Indeed, underlying inflation has been below the 2 to 3 per cent target range since the end of 2015, and Lowe is forecasting it won’t get up into the target range until the end of next year.

This suggests that, in our newly stagnant world, the true NAIRU is a lot lower: 4.5 per cent, maybe 4 per cent. And since, as Lowe reminds us, the RBA’s objectives include “delivering on full employment”, he should be trying harder to get unemployment down to the true NAIRU.

How? By using the one instrument available to him: cutting interest rates to loosen a monetary policy that’s tighter than it needs to be.

Until recently, Lowe’s best reason for not lowering rates was a desire to avoid adding fuel to the boom in house prices (“asset-price inflation”). But now that constraint has lifted, there’s no reason to hesitate.

You could argue that, with households already so loaded with debt, a rate cut may not do much to boost consumer spending. But it probably would lower the dollar, which would improve our industries’ price competitiveness internationally, encouraging them to hire more workers. We’ve got little to lose.

Bank royal commission the start of re-regulation

If you think the banking royal commission’s damning report means you’ll never again be overcharged or otherwise mistreated by a bank, you’re being a bit naive. If you’re hoping to witness leading bankers being dragged off to chokey, you’ll be waiting a while.

But if you think that, once the dust has settled, we’ll find little has changed, you haven’t been paying attention.

I think we’ll look back on this week and see it as the start of the era of re-regulation of the economy. The time it became clear our politicians were no longer willing to give big business an easy ride, to assume it would only ever act in the best interests of its customers and that nothing should ever be done to displease the big end of town, for fear this would damage the economy.

And I’m talking about a lot more than banking, superannuation and insurance. Many other industries have been treating their customers or employees badly, and they too will find governments getting tough with wrongdoers.

Why the change of heart? Because, in so many cases, the 30-year experiment with deregulation, privatisation and outsourcing is now seen to have ended badly.

Recent years have revealed many businesses breaking the law while government regulatory bodies fail to bring them to justice: firms paying their employees less than their legal entitlements, firms taking advantage of foreign students and others on temporary work visas, private providers of vocational education inducing youngsters to sign up for inappropriate courses, irrigators illegally extracting water from the Murray-Darling river system, private inspectors certifying high-rise apartment blocks later found to be seriously defective, and many more.

Big business may have power and money, but customers and employees have votes. And when voters experience mistreatment at the hand of business – or just read about the mistreatment of others – they tend to blame the politicians, who were supposed to ensure such things happened only rarely.

Commissioner Kenneth Hayne has found that almost all the misbehaviour by banks and other institutions he uncovered was already illegal.

He makes the point that “the primary responsibility for misconduct in the financial services industry lies with the entities concerned and those who managed and controlled those entities”.

But, he adds, “too often, financial services entities that broke the law were not properly held to account.

“The Australian community expects, and is entitled to expect, that if an entity breaks the law and causes damage to customers, it will compensate those affected customers. But the community also expects that financial services entities that break the law will be held to account.”

And when the Australian community realises this hasn’t happened, who does it blame? Who does it seek most to punish? The government of the day. Even though the genesis of the policy problem lies in decisions made by governments long gone.

Do you see now why the worm has turned on deregulation?

Former Labor and Coalition governments’ naive faith that “market forces” would oblige businesses to do the right thing has proved badly misplaced. In their scramble for higher profits and pay, seemingly respectable businesses have taken advantage of their greater freedom, knowingly breaking the law whenever they thought they wouldn’t be caught.

And now the chickens have come home, who’s most at risk of losing their jobs? Not the bosses of offending businesses, not the regulators asleep at the wheel, but the government of the day. That’s the rough justice of democracies. Voters hit out at those they have the power to hit – those they elect.

It was business that had the fun, but it’s politicians in most immediate danger of paying the price. Do you really think they’ll be going easy on their former business mates who’ve been dudding them behind their backs?

But what’s a threat to the government is an opportunity for the opposition. Competition between the two parties will ensure the Hayne commission’s recommendations are acted on.

And, whichever side wins the election, the next term will see a tightening of the regulation of many industries beside financial services.

Commissioner Hayne was highly critical of the two main financial regulators, the Australian Securities and Investment Commission and the Australian Prudential Regulation Authority. Why did they allow so much wrongdoing to get past them?

Partly because they succumbed to the ailment threatening all regulators: “capture” by the industry they were supposed to be regulating. They allowed themselves to become too matey with the industry, seeing its point of view more clearly than the interests of its customers.

But there’s more to it. During the decades in which politicians and some economists convinced themselves that the more lightly businesses were regulated the better they’d serve the rest of us, the regulatory authorities were left intact more for appearances than function.

They soon got the message that their political masters – from either side of politics – wanted them to go easy on business. Both sides went for years reinforcing the message by repeatedly cutting the regulators’ funding.

But all that’s changed. The politicians, claiming to be shocked by the regulators’ dereliction, are now pumping in taxpayers’ money as fast as they can go. Life won’t be the same for big business.

Hey pollies: weak wage growth won't fix itself

The economy’s prospects are threatened by various risks from overseas – about which we can do little – and by continuing weakness in wage growth – about which the two sides contesting the May federal election have little desire to talk.

In his major economic speech last week, Scott Morrison gave wages only a passing mention: “by focusing on delivering a strong economy we create the right environment for wages growth, which we are now beginning to see, and more will follow”.

Actually, you need a microscope to see any improvement. The microscope shows that most of it is explained by the Fair Work Commission’s hefty 3.5 per cent increase in minimum wage rates last June.

(And why was it so generous? To offset the effect on pay packets of its earlier decision to phase down Sunday penalty rates.)

Not, however, that Bill Shorten has had a lot more than Morrison to say about the causes and cure of weak wage growth. Presumably, Shorten fears that anything he says about changes to wage fixing will be used to feed yet another scare campaign about him being a patsy for a union takeover.

Two or three years ago, I was happy to entertain the view still publicly espoused by the Reserve Bank (and still happily hidden behind by Morrison) that the wage problem was simply cyclical: wages are taking longer than expected to recover from the ups and downs of the resources boom but, be patient, they’ll come good soon enough.

Sorry, that possible explanation gets harder to believe as each quarter passes without any sign of nominal wage growth moving ahead of weak inflation, so as to give employees their rightful share of the improvement we’ve achieved in the productivity of their labour.

(And thus – ScoMo please note - giving the boost to real household disposable income, then consumer spending and then business investment spending, that has always been the greatest single contributor to “delivering a strong economy”.)

No, as years pass without the cycle restoring real wage growth, it becomes easier to believe the problem arises from some deeper issue with the structure of the economy.

The most popular structural explanation – best espoused by Professor Joe Isaac, an eminent labour economist – is that the “reform” of wage fixing went too far in shifting the balance of industrial bargaining power in favour of employers.

Isaac’s various proposals for reforming the reform – including restoring unions’ right of entry to the workplace, reducing the rigmarole before workers can strike, and restoring permission for industry-wide bargaining – would no doubt have crossed Labor’s mind for serious consideration should it win the election.

But another noted labour economist, former top econocrat Dr Mike Keating, has his doubts. He says he has no great objection to Isaac’s wage-fixing reforms, but doubts they’ll get wages moving because the structural problem is much deeper.

As argued in detail in his book with Professor Stephen Bell, Fair Share, and many articles and blogs, Keating sees our wages problem in the much broader context of the malaise of “secular stagnation” that’s been gripping the US and other advanced economies for at least a decade.

Keating reminds us that wage growth has been weak in most of the advanced economies for several decades, accompanied by rising inequality.

The distribution of earnings (that is, wages, rather than income from all sources) has become more unequal, Keating argues, mainly because of technological change and, to a lesser extent, globalisation.

Technological change has been “skill-biased”, with strong growth in high-skilled employment, and reasonable growth in unskilled jobs, but a decline in middle-level jobs, where routine jobs are being done by computers.

The result is a change in the structure of employment, one which increases earnings inequality. If so, it’s not a problem that could be fixed by higher wage-rates.

Keating says we’ve been slow in Australia to see what’s increasingly been realised overseas and by the international economic agencies: income inequality is bad for economic growth (mainly because the high-paid save rather than spend a higher proportion of their incomes).

But Keating’s more fundamental policy response to the problem of technology-driven weak wage growth and increased inequality is enhanced education and training, to help workers adjust to the challenges posed by new technologies, as well as spur the adoption of those technologies.

He’d give priority to early childhood learning and life-long learning through the TAFE system. He's happy to note this would require us to pay more tax rather than less – another thought the pollies don’t want us thinking about right now.

Rates of tax tell us nothing about economic success

When Leigh Sales of 7.30 asked Scott Morrison what evidence he had to support his claim that the economy would be weaker under Labor because it would impose higher taxes, he replied “I think it’s just fundamental economics 101”. Sorry, don’t think so.

The belief that an increase in taxes must, of necessity, discourage work effort, saving and investing is regarded as a self-evident truth by the well-paid. Similarly with the converse: a decrease in taxes must, of necessity, encourage work effort, saving and investing.

But since no one particularly enjoys paying taxes – and some people really hate it – they would think that, wouldn’t they.

It’s a simple, all-purpose, no-need-to-explain argument against me being asked to pay more tax and in favour of me paying less. What’s not to like?

Just that it misrepresents what economics teaches.

It’s true that some economists emphasise the “deadweight loss” involved in imposing taxes. In principle, a tax distorts an individual’s choices, causing them to do things they otherwise wouldn’t.

This distortion of choices is said to be “economically inefficient”, in that it fails to produce the allocation of economic resources – land, labour and capital – that maximises the “utility” (satisfaction) the community derives.

The degree of allocative inefficiency differs for different taxes, with some said to involve greater deadweight loss than others.

By this logic, one of the worst taxes is conveyancing duty (which discourages people from moving house) and the best is a poll tax (everyone pays the same dollar amount each year which, being impossible to avoid, doesn’t change behaviour).

One thing often not mentioned in economics 101 is that tax on the unimproved value of land (such as council rates) and inheritance taxes score well.

But these calculations are based on theory and assumptions. The first of their limitations is that they ignore the benefits that flow when the taxes are spent. When they’re spent on government provision of “public goods” (goods or services that would be undersupplied if their provision was left to the private sector) they increase allocative efficiency.

You shouldn’t have to go beyond first year economics to learn that changes in the price of something have two effects: an “income effect” and a “substitution effect”.

People who believe an increase in income tax (which is a price) discourages work, and a cut in income tax encourages it, are focusing on the substitution effect and ignoring the income effect.

It’s true that a higher rate of income tax should discourage work by reducing the monetary benefit you get from it, relative to the benefit you get from not working. That is, from enjoying more “leisure”. It thus should encourage you to substitute leisure for work – that is, work less.

 By contrast, lowering the tax on work should encourage people to substitute work for leisure – work more.

Trouble is, the income effect works the opposite way. Increasing income tax reduces your after-tax income. If you don’t want your income to fall, you have to do more work, not less. Similarly, cutting income tax increases your after-tax income, encouraging you to work less.

The fact that the income effect and the substitution effect pull in opposite directions means economic theory can’t tell us whether or not tax increases discourage work. To answer that question you have seek out empirical evidence from the real world.

In doing so you’ll make up for theory’s implicit assumption that money is the only factor motivating people to work. If that’s what you think, you’ve got a lot to learn about human nature.

The empirical evidence says changes in the rate of income tax for “primary earners” – the main person a family relies on for income, who’s usually working full-time – aren’t great.

It’s only “secondary earners” - often women working part-time – whose hours of work are much influenced by increases or decreases in income tax.

This is pretty obvious when you think about it. The number of hours worked by full-time employees is set by their boss, whereas part-timers have some degree of control over the hours they work. Certainly, they decide whether they want to move from part-time to full-time.

Let me tell you: politicians’ motive for tax cuts is almost always more political than economic. If Morrison was really on about encouraging more work, his tax cuts would be aimed at working mothers, not the highly paid full-timers they are aimed at.

But there’s another empirical test of his confident assertion that high rates of tax discourage economic growth and low rates encourage it.

If that were true it should also be true that countries with high tax rates have low living standards, whereas countries with low tax rates have high living standards.

Try as they might, however, economists have never been able to find an inverse correlation between the level of taxes and a country’s rate of growth.

For a start, the poor countries have much lower rates of total taxation than the rich ones. Rich countries have high tax rates so they can enjoy the many benefits of being rich: the welfare state, good public infrastructure, good health care, good education and much else.

The Organisation for Economic Co-operation and Development regularly publishes figures for their 35 member-countries’ rates of total taxation (federal and state) as a percentage of gross domestic product.

Its latest figures, for 2017, show its rich-country members ranging from 46 per cent for France and Denmark to 23 per cent for Ireland. Sweden is on 44 per cent, Germany on 37.5 per cent.

The average for the whole OECD is 34 per cent, with us on about 28 per cent and the United States on 27 per cent (but with a much bigger budget deficit).

If they don’t tell you all that in economics 101, ask for your money back.

Unhealthy, unhappy lives aren't fair exchange for higher incomes

In his Australia Day address, social researcher Hugh Mackay said that "the Australia I love today – this sleep-deprived, overweight, overmedicated, anxious, smartphone-addicted society – is a very different place from the Australia I used to love".

He identified three big changes: the gender revolution, increasing disparity in wealth, and social fragmentation.

He approves of the first, but laments that we’re "learning to live with a chasm of income inequality" and that social fragmentation means Australians are become "more individualistic, more materialistic, more competitive".

The third big change, he said, posed the biggest challenge – preserving social cohesion.

Earlier this month, the playwright David Williamson lamented that, since the advent of neoliberalism, "the world has become a nastier, more competitive, more ruthless place".

"There’s no perfect society, but I don’t think it needs to be as brutal as it is now."

As we move on from our officially required season of national navel-gazing – "yes, but what does it mean to be Australian?" – these concerns are worth pondering.

Economists object to being blamed for every ill that’s beset our country in the past 40 years. Where’s the proof that this economic policy or that has caused a worsening in mental health, they demand to be told.

It’s true that few developments in society have just a single cause. It’s also true there’s little hard evidence that the A of “microeconomic reform” caused the B of more suicides, for instance.

But there’s a lot of circumstantial evidence. After all, the specific objective of micro reform was to increase economic efficiency by making our markets more intensely competitive. The economists’ basic model views us as individuals, motivated by self-interest, and the goal of faster growth in the economy is aimed at raising our material standard of living.

And if some of our problems stem from changing technology – pursuing friendship via screens, for instance – can economists disclaim all responsibility when one of their stated aims is to encourage technological advance in the name of higher productivity?

Economists assume that economic growth will leave us all better off. Most take little interest in how evenly or unevenly the additional income is shared between households.

The Productivity Commission’s recent and frequently quoted report, finding that the distribution of income hasn’t become more unequal, refers to recent years, not the past 40. And the report averages away the uncomfortable truth that the incomes of chief executives and other members of the top 1 per cent have increased many times faster than for the rest of us.

Sometimes what’s happened since the mid-1980s reminds me of the old advertisement: are you smoking more, but enjoying it less?

Our real incomes have grown considerably over the years – even for people at the bottom – and economic reform can take a fair bit of the credit. It can take most of the credit for the remarkable truth that, unlike all the other rich countries, we’ve gone for 27 years without our least fortunate experiencing the great economic and social pain of recession and mass job loss.

But though most of us are earning and spending more than ever, there’s evidence we’re enjoying it less. Our higher material living standards have come at the cost of increasing social and health problems.

Is that so hard to believe when the key driver of our higher incomes is more intense competition between us?

Economists generally take little interest in social and health problems, regarding them as outside their field. But though problems such as loneliness, stress, anxiety, depression and obesity were with us long before the arrival of neoliberalism, they seem to have got worse since the mid-1980s.

Last year, Dr Michelle Lim, a clinical psychologist at Swinburne University, and her colleagues produced the Australian Loneliness Report, which found that more than one in four Australians feels lonely three or more days a week.

It’s most common among those who are single, separated or divorced. Compared to other Australians, the lonely report higher social anxiety and depression, poorer psychological health and quality of life, and fewer meaningful relationships and social interactions.

Turning to increased stress, it’s an inevitable consequence of living in bigger, faster cities and working in more competitive workplaces. Our bodies respond to stressful events with a surge of adrenaline, which increases our reaction speed and helps ensure our survival.

Trouble is, our bodies aren’t designed to cope with repeated stressful events and adrenaline rushes. Our readiness for fight or flight doesn’t decline, and we remain permanently aroused, which damages our health, making us more at risk of a heart attack or getting sick in other ways.

If more "jobs and growth" and the higher incomes they bring are intended to make us happier, maybe governments would do better by us if they switched their objective from increasing happiness to reducing unhappiness.

For instance, if the banks are now being criticised on all sides for putting profits before people, why are governments – facing an epidemic of obesity and diabetes - so respectful of the food and beverage industry’s right to continue fatten its profits by fattening us and our kids?

Give economists a PC and they start making more sense

Economies turn down and back up, but one of the biggest, long-running economic stories of our time is the way the digital revolution is disrupting one industry after another. So let me tell you how it’s changing the academic study of economics.

You probably imagine the economic research carried out in universities is terribly theoretical and impractical. It used to be, but not anymore.

You can trace the progress of academic economics by looking at who’s been awarded the Nobel memorial prize in economic sciences from about 2001 onwards, and what they did to deserve it. Of course, there’s usually a long delay between when you make your seminal contribution and when you get your gong.

Until the turn of the century, the prize usually went to people elaborating on orthodox neo-classical theory, particularly by shifting to mathematical reasoning.

It may surprise you that the man who wrote the most popular introductory textbook of the post-war years, Paul Samuelson, was also the individual who did most to turn economic reasoning from words and diagrams to equations.

The development of the first mathematical “econometric” models of the macro economy was another important advance.

It was about 30 years ago that the frontier of economic research took a more realistic turn by shifting to the study of “imperfect competition”, where the idealised assumptions of the simple neo-classical model of markets were critically examined.

In 2001, for instance, the prize was shared by three American economists – George Akerlof, Michael Spence and Joseph Stiglitz – for their demonstration that, rather than being perfectly shared by everyone in a market, information is usually asymmetric – with sellers knowing more than buyers – and, rather than being costless, is expensive to acquire.

Another example: Paul Krugman got his gong in 2008 for demonstrating that there’s more to international trade than just each country pursuing its “comparative advantage”, as mainstream theory assumes.

It was about 40 years ago that the psychologist Daniel Kahneman (gonged in 2002) and the rebellious economist Richard Thaler (2017) began formulating behavioural economics, an advance on the neo-classical assumption that all decision-making is rational. Robert Shiller got his in 2013 for his study of non-rational behaviour in financial markets.

But recent studies of articles in the world’s top economic journals (mainly American) have shown that, since about the turn of the century, theoretical papers have largely been replaced by empirical studies of particular relationships in particular markets (competition between male and female drivers in Japanese speedboat races, for instance).

This shift from deducing conclusions from assumption-based theory to examining the relationships between real-world variables, to see how the theory measures up, is a big improvement. But why has it happened?

I give most credit to the information revolution. Computerisation has hugely increased that number of “data sets” of business information waiting to be discovered and subjected to statistical tests by academic economists checking hypotheses or just looking for interesting relationships.

All of which is easily done using programs on your personal computer, rather than waiting your turn for time on the main-frame. And it fits with economists’ modern addiction to using stats and maths for “academic rigour”.

As part of their greater interest in empirical evidence rather than what theory tells us should be the case, economists have started doing something they long believed was impossible: economic experiments – including searching out “natural experiments”, such as the famous study of two nearby cities in different US states, where one state raised the minimum wage and the other didn’t.

By the standards of real mathematicians, economists’ maths isn’t that fancy, but it’s more advanced than used by others in the social sciences. Economists have made more progress in moving from finding correlations to establishing causal relationships than the psychologists have – which probably means they get more research funding.

It also means there’s less resistance from international journals to publishing research about that uninteresting and unimportant place called Australia. I’m told doctoral students come to Oz because they’ve heard we have good data sets.

The risk, however, is that research projects are chosen because good data are available, rather than because the questions being answered are important to our understanding of how the economy works and to finding better solutions to our economic problems.

We don’t want academic economists losing interest in their theory, we want them using their empirical evidence to improve it. Making it more realistic and thus more reliable in its predictions about what happens if you do X, or whether policy A or policy B is more likely to improve things.

You'd be surprised what's propping up our living standard

It’s the last lazy long weekend before the year really gets started, making it a good time to ponder a question that’s trickier than it seems: where has our wealth come from?

The question comes from a reader.

“Australia has been without a recession for 25 or more years, the economy seems booming to me, just by looking around: employment, housing prices, explosive building in major capitals, etc. Where is the wealth coming from? Mining? Other exports? Because the resources have to come from somewhere,” he writes.

That’s the first thing he’s got right: it’s not money that matters (the central bank can create as much of that stuff as it sees fit) it’s what money is used to buy: access to “real resources” – which economists summarise as land (including minerals and other raw materials), labour and (physical) capital.

But here’s the first surprise: of those three, when you trace it right back, probably the most important resource is labour – all the work we do.

The first complication, however, is the word “wealth”, which can mean different things. It’s best used to refer to the value of the community’s assets: its housing, other land and works of art, the equipment, structures and intellectual property owned by businesses (part of which is represented by capitalised value of shares on the stock exchange), plus publicly owned infrastructure (railways, roads, bridges and so forth) and structures.

To get net wealth you subtract any debts or other liabilities acquired in the process of amassing the wealth. In the case of a national economy, the debts we owe each other cancel out, leaving what we owe to foreigners. (According to our national balance sheet, as calculated by the Australian Bureau of Statistics, at June last year our assets totalled $15.4 trillion, less net liabilities to the rest of the world of $3.5 trillion.)

But often the word wealth is used to refer to our annual income, the total value of goods and services produced in the market during a year, as measured by gross domestic product (which in the year to June was $1.8 trillion).

The people in an economy generate income by applying their labour to land and physical capital, to produce myriad goods and services. Most of these they sell to each other, but some of which they sell to foreigners. Why? So they can buy other countries’ exports of goods and services.

Only about 20 per cent of our income comes from selling stuff to foreigners and only 20 per cent or so of the stuff we buy comes from foreigners. This exchange leaves us better off when we sell the stuff we’re better at producing than they are, and buy the stuff they’re better at than we are.

Much of what we sell to foreigners is minerals and energy we pull from the ground and food and fibres we grow in the ground. So it’s true that a fair bit of our wealth is explained by what economists call our “natural endowment”, though it’s also true that we’re much more skilled at doing the mining and farming than most other countries are.

Speaking of skills, the more skilled our workers are – the better educated and trained – the greater our income and wealth. Economists call this “human capital” – and it’s worth big bucks to us.

How do the people in an economy add a bit more to their wealth each year? Mainly by saving some of their income rather than consuming it all. We save not just through bank accounts, but by slowly paying off our mortgages and putting 9.5 per cent of our wages into superannuation.

It’s the role of the financial sector to lend our savings to people wanting to invest in the assets we count as wealth: homes, business structures and equipment and public infrastructure. So if most of our annual income comes from wages, most of our savings come from wage income and our savings finance much of the investment in additional assets.

But because our natural endowment and human capital give us more investment opportunities that can be financed from our savings, we long have called on the savings of foreigners to allow us to invest more in new productive assets each year than we could without their participation.

Some of the foreigners’ savings come as “equity investment” – their ownership of Australian businesses and a bit of our real estate – but much of it is just borrowed. These days, however, our companies’ (and super funds’) ownership of businesses or shares in businesses in other countries is worth roughly as much as foreigners’ equity investments in Oz, meaning all our net liability to the rest of the world is debt.

Naturally, the foreigners have to be rewarded for the savings they’ve sunk into our economy. We pay them about $60 billion a year in interest and dividends, on top of the interest and dividends they pay us.

The main thing we get in return for this foreign investment in our economy is more jobs (and thus wage income) than we’d otherwise have, plus the taxes the foreigners pay.

People worry we can’t go on forever getting wealthy by digging up our minerals and flogging them off to foreigners. It’s true we may one day run out of stuff to sell, but our reserves – proved and yet to be proved – are so huge that day is maybe a century away (and the world will have stopped buying our coal long before we run out).

A bigger worry is the damage we’re doing to our natural environment in the meantime, which should be counted as reducing our wealth, but isn’t.

But mining activity accounts for a smaller part of our high standard of living than most people imagine – only about 8 per cent of our annual income.

Most of our prosperity – our wealth, if you like – derives from the skill, enterprise and technology-enhanced hard work of our people.

More jobs for older workers than ever before

“Too old, too senior, too experienced, too expensive – heard ’em all. Ours is a society which does not value age and lived experience. Over 50? It’s the scrap heap for you.”

I can’t remember where I saw that quote, but I bet you’ve heard those sentiments many times. The media are always bringing us stories about people who, having lost their job in late middle age, find it very hard – even impossible - to get another one.

It’s understandable that people experiencing such treatment get pretty bitter about it. And it’s not surprising the media and the politicians take their complaints so seriously. The federal government has appointed successive age discrimination commissioners, and instigated various schemes offering subsidies to employers willing to hire older workers.

All of which is just as likely to increase prejudice as reduce it. The more public figures bang on about the prevalence of age discrimination, the more they risk sending a message to employers that if everyone else is ridding themselves of older workers, why aren’t they?

And if older workers weren’t sub-standard, why would the government find it necessary to subsidise their cost?

It would be silly to deny that some employers are prejudiced against older workers – just as some are prejudiced against young workers (an injustice the media are far less eager to tell us about).

But it’s just as silly to leap from the truth that some proportion of older workers has trouble finding re-employment to the outlandish claim that every worker over 50 is headed for the scrap heap.

I don’t know the true extent of discrimination against older workers, but I’m pretty sure we’ve been given an exaggerated impression of it, with many older workers caused to worry unnecessarily.

If there was any truth to the notion that everyone over 50 is headed for the scrap heap, we should be seeing a sharp decline in the rate at which people over 50 are participating in the labour force.

But we’re not. Indeed, the reverse is happening. The statistical truth is that the participation rates of older age groups are higher than they’ve ever been – a point Reserve Bank governor Dr Philip Lowe made in a little-noticed speech last year.

The ageing of the population – and, more particularly, the retirement of the baby-boomer bulge – means the proportion of older people working should have declined. Remarkably, it’s increased.

There was a time when early retirement was all the rage. As soon as you could retire, you did. And a lot of workers were retired involuntarily.

But those days are long gone. The age at which men and women are retiring keeps rising. In the 1980s and ‘90s, less than one worker in 10 was over 55. Today it’s almost one in five.

Since 2000, the “participation rate” for men aged 55 to 64 has risen from 60 per cent to about 67 per cent. The rate for women has been rising since the early ‘80s – from 20 per cent to 60 per cent.

For men aged 65 and over, the participation rate has risen since 2000 from 10 per cent to almost 20 per cent. (Read that again if it didn’t sink in.) For women in the same age group, participation has gone from a per cent or two to about 10 per cent.

The big news is that older people are staying longer in the workforce than ever before, but the story we’re being fed is that employers are discriminating against older workers wherever you look.

How has this remarkably under-reported truth come about? Partly for negative reasons. The higher cost of homes has caused people to take on mortgages later in life, meaning some people have higher levels of mortgage debt as they approach retirement and don’t want to stop working until it’s paid off.

The knowledge that we’re living longer – combined with the super industry’s unceasing efforts to convince us we haven’t saved enough – has prompted some people to delay their retirement.

Governments have lifted the age pension age to 65 for women, and are now phasing the age for both sexes up to 67. They’ve also raised the age at which you may access your superannuation savings.

But then there are the positive reasons. The present generation of older workers is much healthier than earlier generations.

And we’re living longer. Which makes it hardly surprising we’re working longer. Of course, another factor that’s helping is greater acceptance by employers of “flexible work practices” – including allowing workers to shift from full-time to part-time. That is, there’s been a rise in semi-retirement.

Then there’s the fact that more and more people work in the services sector, in jobs that tend to be less physically demanding.

But perhaps the biggest factor is the delayed effect of the trend for most mothers to return to the workforce after childrearing. Now more of them are still working decades later.

Oldies are always expounding on the supposed shortcomings of the younger generation. But there’s one respect in which oldies set youngsters a bad example: they’re champions at feeling sorry for themselves – even when the facts don’t back them up.
