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.

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.

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.

Positions vacant: economists (women preferred)

Never in the field of economic conflict was so much analytical effort devoted to so few... as in Reserve Bank governor Philip Lowe’s one-man crusade to save the economics profession.

This latter-day Lord Kitchener wants more young Australians studying economics at high school and university, then enlisting as economists in the holy war against economic inefficiency.

His message: Your country needs you. Opportunity cost is being flouted on every hand, yet we have just 3000 professional economists fighting the tide of economic illiteracy.

Young women, in particular, should look at themselves in the mirror and ask the hard question: what good reason have I not to become an economist? Why should I squander my life on any lesser calling than the orderly regulation of mammon?

And let’s have no weak excuses that you know nothing about being an economist – what kind of people they are, what they do, where they work, how hard it is to find a job. Not forgetting a question that could cross the mind of someone with the right stuff to be a dismal scientist: how well does it pay?

Field marshal Lowe has had his people working night and day scouring data bases far and wide to answer all such questions. Rochelle Guttmann (ably assisted by James Bishop, a mere male) does so in the subtly titled paper, Does It Pay to Study Economics? taken from my rapidly dwindling pile of unused reports, seasonally adjusted from 2018.

According to the 2016 census, fewer than 3000 people work as economists, even though there are 73,000 people with post-school qualifications in economics. What’s worse, only about two-thirds of people working as economists actually hold a qualification in economics.

But this is misleading. It’s not nearly that bad. For a start, the 3000 excludes about 2000 academic economists, who are classed as university lecturers. More significantly, to be classed as holding a qualification in economics, you must have that word in the name of your degree.

This is silly. In the day, the title of your degree said as much about which uni you went to as about the subject you majored in. Economics majors at Melbourne or UNSW walked away with a BCom, whereas accounting majors at Sydney got a BEc.

Little wonder people holding an “economics” degree are more likely to work as an accountant than as an economist. And you can forget the notion that a third of working economists are unqualified academically.

Returning to the recruiting drive, the authors make two observations about the huge disparity between those having done an economics degree and those getting a job as an economist.

First, it probably shows it’s hard for someone with an economics degree to actually get a job as an economist (ie, S > D). But it probably also shows that an economics degree is generalist in nature and provides a breadth of skills that allows you to work in a broader range of jobs compared to other degrees.

Get this: “80 per cent of economics graduates work in high-skilled white-collar occupations”.

More than a third of economists (narrowly defined) work in public administration, well over a quarter in private-sector professional services and about 15 per cent in financial services. But people with economics degrees work in a broader range of occupations and industries than people with degrees in most other fields.

Whether you’re talking economists or people with economics degrees, more than 60 per cent of them are men. Lowe believes – as does his teenage daughter, apparently – this disparity must be corrected. (The daughters of powerful men are far more influential than is commonly understood.)

Now to the question no economist would regard as sordid. Figures from the Australian Tax Office say economists have hourly earnings that put them in the top 3 per cent of earnings by occupation.

Graduates with economics degrees typically have higher full-time earnings than other graduates. They’re comparable with STEM (science, technology, engineering and maths) degrees, and higher than for business and other social science degrees.

Guttmann and her male sidekick say the labour market tends to pay the highest wages to people with the skills, abilities and knowledge that are in shortest supply [relative to employers’ demand].

So which skills make economists well-paid? Apart from their knowledge of economics, economists have skill in maths that’s way above the average for other skilled occupations, and above-average analytical skill, for reasoning and problem solving (which is what brings the big bucks).

Looking for the catch? You’ve found it. If you’re weak on maths, you might be happier as a journo.

Compared to you and me, the feudal serfs had it easy

Back at work yet, or still enjoying your summer break? Either way, you probably wish you had more annual leave. I could tell you to count your blessings, that today’s full-time workers get much longer holidays than workers have ever had.

But maybe that isn't true. It’s certainly true that we get longer holidays and work fewer hours than workers did in the 19th century but, according to the sociologist Juliet Schor, the 19th century – not long after the end of the Industrial Revolution – was an aberration in the history of human labour.

Indeed, if we’re to believe Dr Lynn Parramore, senior research analyst at the Institute for New Economic Thinking, we’re working a lot harder than medieval peasants did. “Ploughing and harvesting were backbreaking toil,” she says, “but the peasant enjoyed anywhere from eight weeks to half the year off.”

The church, mindful of how to keep a population from rebelling, enforced frequent holy-days. Weddings, wakes and births might mean a week off, quaffing ale to celebrate, and when wandering jugglers or sporting events came to town, the peasant expected time off for entertainment, she says.

There was no work on Sundays, and when ploughing and harvesting seasons were over, peasants got time to rest, too. In fact, according to Schor, during periods of particularly high wages, such as 14th century England, peasants might put in no more than 150 days a year.

I’m not sure every scholar would agree with this assessment, and the 14th century was the tail end of England’s feudal system, which began after the French Norman Conquest of England in 1066.

So if you’re not sure you’d have been happier as a serf – good thinking.

Feudalism was the system of political and economic organisation that preceded England’s Agricultural Revolution and Industrial Revolution, before we got to a capitalist or market economy approximating what we have today.

According to the father of modern economics, Adam Smith, feudalism was a social and economic system defined by inherited social ranks, each of which possessed social and economic privileges and obligations. Wealth derived from agriculture, which was arranged not according to market forces but on the basis of customary labour service owed by serfs to landowning nobles.

The king owned all the country’s land, but leased much of it to nobles, often called barons. The barons ran the decentralised, feudal system. These “lords of the manor” were in complete control of their manor, meting out justice, minting their own money and setting their own taxes.

The barons divided some of their land between their knights. The knights, in turn, distributed some of their land to the serfs, also known as villeins or peasants.

That covers people’s privileges, now their obligations. In return for their land, the barons paid rent to the king and provided him with knights to fight his battles when required. In return for their land, the knights provided their baron with personal protection and military service to the king.

In return for their land, the serfs paid their master with maybe a third of the food they grew, as well as being compelled to work on his own land. They couldn’t leave the manor and needed their lord’s permission to marry. They were often charged a fee for use of any of the improvements on the manor – roads, bridges, mills and bakehouses. And sometimes they had to fight in the baron’s battles.

Serfs lived with their animals in one-room homes they built themselves with wattle-and-daub (woven twigs daubed with mud). Their clothes were self-made, mainly of wool and very scratchy. They grew rye, wheat and other grains, grazed sheep on the common, had a kitchen garden and a few apple and pear trees.

Most of what they ate they grew themselves: little meat, but lots of rye bread and a stew of peas, beans and onions, called pottage. Berries, nuts and honey were gathered from the woods.

The feudal system fell into decline for many reasons. One was that the military became full-time professionals. Another was the Black Death (bubonic plague) of 1348, which killed many of the serfs. Landowners desperate for workers to harvest their crops had to do the unthinkable: pay actual wages to anyone who’d work their land – and the wages were high. Thus did the lords lose their hold over the serfs.

But Professor Richard Grabowski, of Southern Illinois University, has advanced a more economic theory. Manorial agriculture wasn’t very efficient, even though productivity could have been improved by such measures as removing stones from fields, adding mineral fertilisers and making greater use of fodder crops.

But the system of forced labour precluded use of these techniques because they required more care and skill than the serfs had any incentive to apply when working in the lord’s fields rather than their own.

Creating this incentive would have required shifting to paid labour, but this would cost the lord the ability to order his serfs to help fight a rival lord trying to grab his land. The first lord to free his serfs would lose his land to the others.

So the lack of national enforcement of property rights was another barrier to greater productivity. As the feudal system gradually broke down, the basis for power shifted from how many serfs you controlled to how good you were at using your land to generate more income.

England’s long Agricultural Revolution involved moving to market relationships between land owners and labourers, and almost all rural production being sold in markets, as well as huge improvements in agricultural productivity, making the nation much more prosperous.

People may have worked more hours on more days in the year, but they were much better paid to do it.

Indigenous small business is on the rise

It’s the season of good cheer, so let me give you some good news: we’re not making the progress we should be in Closing the Gap between Indigenous and non-Indigenous Australians, but when it comes to increasing the ranks of Indigenous small-business people we’re doing surprisingly well.

The number of Indigenous owner-managers is conservatively estimated to have increased by 32 per cent between 2006 and 2011, and by 30 per cent between 2011 and 2016.

That’s coming off a low base but, even so, the number increased from 10,400 to 17,900 over the decade to 2016. This took the proportion of Indigenous owner-managers in the over-15 population from 3.2 per cent to 3.4 per cent.

This may not seem much, but it occurred while the proportion of non-Indigenous owner-managers actually decreased from 10 per cent to 8.6 per cent – a fall that probably reflects the difficulties affecting the economy since the global financial crisis in 2008.

It says Indigenous small businesses are making headway in the economy despite its relatively low growth over the past decade.

The figures have been derived from census data in a paper by Siddharth Shirodkar and Dr Boyd Hunter, of the Centre for Aboriginal Economic Policy Research at the Australian National University, and Professor Dennis Foley, of the University of Canberra.

The authors note that the historical exclusion of Indigenous Australians from mainstream economic life has led to low accumulation of wealth across many Indigenous communities. Only a relative few gained formal business experience before the past decade.

The result is that the vast bulk of entrepreneurially inclined Indigenous Australians probably lack the key preconditions to start a business and prosper in our capitalist economy, they say.

Today, however, things are improving – to some extent as a result of government policy. In 2015, the Indigenous Procurement Policy established targets for federal government departments to buy what they needed from Indigenous suppliers.

The value of successful tenders by Indigenous business owners has grown from about $6 million in 2012-13 to more than $1 billion in the policy’s first two and a half years to the end of 2017. Today, more than 1000 indigenous businesses are contracting with the feds.

This year the government also announced the Indigenous Business Sector Strategy, which includes measures to provide greater business support, improved access to finance, stronger connections to business networks and better sharing of information about commercial opportunities.

But all of that is insufficient to explain the rise in Indigenous enterprise over the past decade. And get this: official analysis of the register of Indigenous businesses suggests that Indigenous-owned firms are between 40 and 50 times more likely to hire Indigenous employees than are non-Indigenous firms.

So the establishment of Indigenous businesses is an important mechanism to deliver economic development and increased Indigenous participation in the workforce. And this, the government tells us, is shifting the narrative from welfare and dependence to aspiration, empowerment and independence. (A lovely thought – if only it had more substance.)

Certainly, “Indigenous entrepreneurs offer their community an avenue for greater and long-overdue economic self-determination, create positive role models within families and communities, and can serve as mentors to young, entrepreneurial Indigenous Australians,” as the authors say.

The businesses these owner-managers run are spread across Australia, but the vast majority of owner-managers are located on the east coast, particularly in greater Sydney and the rest of NSW. Large numbers also live in Brisbane, the rest of Queensland and in Melbourne.

The growth in capital cities over the past decade has occurred at double-digit rates except in Darwin, where the number of Indigenous businesses fell over the five years to 2016.

But the pattern in the regions was mixed. In regional parts of NSW, Queensland and Victoria there was double-digit growth over the decade, with the number in regional NSW doubling to more than 2700.

In regional South Australia, Western Australia and Tasmania, however, numbers remained flat between the censuses of 2011 and 2016. And they actually fell by 44 per cent in regional Northern Territory.

This could partly reflect the reduction in business opportunities following the end of the resources boom, though the same effect isn’t apparent in regional Queensland, probably because its business activities are more diverse.

But mining doesn’t fully explain the falls in the NT. Here the feds’ NT “intervention” may be to blame.

The largest declines in the number of owner-managers were in remote regions of the NT and very remote parts of WA. This reinforces the story that remote areas, where about 20 per cent of the Indigenous population lives, are underdeveloped in terms of access to markets. Clearly, it’s getting worse.

Abolition of the Community Development Employment Projects scheme may be another part of the explanation. These involved local community-run organisations creating work experience for participants and opportunities to work in communities and meet community needs through small-scale activities not otherwise funded.

Funding provided for the scheme was used to support the on-costs for these community organisations. Its abolition led to the closure of many of them. Even if they were unlikely to have owner-managers associated with them in the census, they may have supported other local enterprises by providing them with low-cost or subsidised labour.

You can argue that, by giving people subsidised jobs and solutions to community needs, the scheme robbed them of the incentive to find real, better-paid jobs and start unsubsidised businesses but, as the decline in owner-managers suggests, that doesn’t justify simply pulling the plug without providing a better substitute.

Smacks to me of controlling the growth in government spending at the expense of the most disadvantaged people in the most remote parts of the country, where opportunities to lift yourself up by your bootstraps are even rarer than in comfortable middle-class electorates.

Tax reform is pushed by rich males, for rich males

I know it’s a shocking thing for an economics writer to confess, but I’ve lost my faith in the Search for the Golden Tax System. I no longer believe that reforming our tax system is the magic key to improving the nation’s economic and social wellbeing.

As we start to review the modest achievements of the Abbott-Turnbull-Morrison government over the past five years, business people, economists and accountants are lamenting its lack of progress on tax reform.

It raised expectations of sorely needed reform, then wilted at the first hint of political difficulty. The Rudd-Gillard-Rudd government did little better in its six years.

So, the zealots are telling us, the tax system remains unreformed, a millstone around our economy whose threat to our future becomes ever-more urgent. Every so often, one of the big four firms of chartered accountants comes up with its own plan to fix everything.

Sorry, not buying. It’s true our tax system is far from ideal, but if after decades of trying we’re still no closer to nirvana, it’s doubtful we ever will be.

Meanwhile, other aspects of the economy just as important to our present and future wellbeing, and just as in need of “reform”, languish while we obsess about taxes.

Such as? Education and training. Health. Cities with long commute times. “Sorry, we’ll get on to it as soon as we’ve increased the GST.”

The never-ending quest for tax reform is being promoted partly by econocrats, tax economists and tax accountants who specialise in the topic and have little to contribute on other issues.

But the biggest push is coming from rich white males in big business. Their goal is to “reform” the tax system so that they and their company pay less and others pay more. No matter how long it takes, they won’t “move on” until they’ve got what they want.

She didn’t put it this way, but the truth that tax “reform” has long been pushed by well-off men for their own benefit – and at the expense of less well-paid women – was demonstrated in a paper given at a tax conference last week by one of our leading tax economists, Professor Patricia Apps, of the University of Sydney Law School.

She showed how the Productivity Commission’s recent report finding there’d been no increase in inequality in recent decades rested on lumping couples’ incomes together, ignoring the difference in contributions by each partner and, in particularly, assuming that “home produced goods and services” - such as childcare, cooking or cleaning - make no contribution to the family’s standard of living, so can be ignored when they have to be bought in because both partners are working.

To be fair, the commission did its analysis the way it’s usually done. But that’s because such analysis is mainly done by men, to whom it never occurs to take account of home production.

Apps used samples of more than 2400 households from the official household expenditure surveys in 2004 and 2016 to divide their income between that contributed by the “primary earner” (mainly male) and the “secondary earner” (mainly female). Primary earners were aged between 20 and 60.

She found that over 12 years, the incomes of primary earners’ in the bottom decile (group of 10 per cent) rose by 53 per cent, increasing to a 78 per cent rise for those in the eighth decile and 124 per cent for the top decile. Look like rising inequality to you?

Then she estimated the income tax those primary earners paid, after adjusting for inflation. Comparing the last year with the first, those in the bottom decile got a real tax saving of $1450 a year, whereas those in the top decile got a saving of $12,340 a year.

So, high income earners benefited most. But get this: after the bottom decile the tax saving fell to a low of $200 for the fifth decile and $370 for the sixth. It then started rising slowly until it leapt for the top decile.

See what’s happened? Very low income earners have done OK, earners at the very top have done brilliantly, and people around the middle have got peanuts. Guess where the (mainly female) secondary earners are likely to be congregated?

Of course, the high income-earners keep telling us their tax rates need to be cut to encourage them to work harder. But Apps has calculated the workers’ “labour supply elasticity”. In effect, she finds it’s very elastic (price-sensitive) for part-timers, but quite inelastic for full-timers, particularly those who’re highly paid.

Looking at primary earners in the top decile, she found that, despite their huge pay rise over the 12 years, and their generous tax cuts, the average number of hours they were working was virtually unchanged.

The various tax changes we’ve had – which aren’t nearly enough to satisfy the tax reformers – have favoured (mainly male) high income-earners, without any sign it’s made them work more.

The people whose decisions about whether to leave the home to do paid work, or to move from part-time to full-time, are those most likely to be affected by the tax they have to pay, but are no better off and probably worse off.

No prize for guessing these are mainly women with children. All this is long known by true tax experts – but just as long ignored. Tax reform is a game for well-off men on the make. Wake me when the women take over.

How economists lost their fear of minimum wage rises

Do rises in the minimum wage come at the expense of jobs? If you listen to the employer groups, they certainly do. But this is a question on which economists have changed their tune.

So much so that the latest issue of the Reserve Bank’s Bulletin includes an article by one of its researchers, James Bishop, concluding there’s no evidence that modest, incremental increases in minimum award wages have an adverse effect on hours worked or the rate of job destruction.

There’s no way the Reserve would have said such a thing 20 years ago.

For decades, most economists did believe increases in the minimum wage would cause employment to be lower than otherwise if they took the wage rate above where market forces would have set it – the “market-clearing” price at which the quantity supplied and the quantity demanded were equal.

Their certainty came from elementary economic theory. Their simple “neo-classical” model of markets, the bedrock on which most economists’ thinking is based, told them that if you raise the price of something without any change in its supply, you’ll cause less of it to be demanded.

That was as true for the price of labour as it was for the price of bananas or anything else.

This continued to be the conventional wisdom among economists until 1994, when two American economists, David Card and Alan Krueger, published the results of their “natural experiment” in which they compared what happened in 410 fast food restaurants in two adjoining states after New Jersey raised its minimum wage by 19 per cent but Pennsylvania didn’t.

To much amazement, they found that the rise in the price of labour actually led to a small rise in employment, not a fall.

In other words, they checked the theory against the real world and found it wanting.

This implied that the simplified model of demand and supply might be good for predicting the consequences of a rise in the price of bananas, but it isn’t much good at predicting developments in a market where every unit of labour is different and comes with a human attached.

A model that could predict the outcome Card and Krueger found is one that assumes employers have a degree of market power over wages, allowing them to fix wage rates below where a free market would put them, until the government intervened.

Card and Krueger’s challenge to the conventional wisdom set off decades of empirical studies throughout the developed world trying to replicate or refute their findings. Not surprisingly – since academic economics is riven by ideological conflict – they found both.

Bishop says that, on balance, the weight of evidence is that “modest and incremental increases in minimum wages do not have significant adverse effects on hours worked and job loss”.

But Australia’s system of minimum wages is very different to other countries’ systems, and there hasn’t been much empirical testing here.

Countries such as Britain, Germany and New Zealand set a single national minimum wage; in the United States it varies by state.

In Oz we, too, have a national minimum wage, but we also have more than 100 industrial awards covering particular industries or occupations, each of which sets a number of minimum wage rates for particular job classifications covered by that award.

Awards cover those aspects of employees' pay and conditions that they’re permitted to cover by the national Fair Work Act. Awards are awarded by the Fair Work Commission after submissions from unions and employer groups and they have the force of law.

Pay someone less than the minimum amount specified in the relevant award and you’re breaking the law.

It’s true, of course, that many workers’ pay – a good third of all employees – is determined by their enterprise agreement rather than their award. The wage rates specified in agreements are usually a fair bit higher than those in the award.

Roughly 40 per cent of employees are covered by “individual arrangements” between the individual and their employer, which may be formal (written) or informal. These wage rates need to be at least as high as provided in the individual’s award.

Not a huge number of workers depend on the national minimum wage (of $18.93 an hour, $719 a week and $37,406 a year), but many workers are paid according the much higher minimums set out in their award.

And here’s the trick: when, after a public hearing, the Fair Work Commission decides by how much it will increase the national minimum wage on July 1 each year, it increases the thousands of minimums set out in awards by the same percentage. (The highest award minimum is $171 an hour.)

So our minimum wage directly affects the wages paid to about a quarter of all employees. That’s a much higher proportion than in the other rich economies.

What’s more, the minimum wage increase probably affects many more workers indirectly, particularly those on individual arrangements.

Our national minimum wage has long been among the highest in the rich countries, both in its absolute level and relative to the median wage.

Consider this: while the wage price index has been rising by only about 2 per cent a year in recent years, the annual increase in the minimum wage was 3.5 per cent this year, 3.3 per cent last year and 2.4 per cent in 2016.

All these are the reasons it was important for Bishop to study our minimum wages to check that the broad conclusions reached in other countries also apply to us.

He did, and they do. He finds that our minimum wage increases “appear to have no discernible adverse effect on hours worked or job loss”.

But minimum wages being the contentious topic they are, he’s quick to add some qualifications.

“The results do not necessarily generalise to large, unanticipated changes in award wages. There will always be some point at which a minimum wage adjustment will begin to reduce employment significantly,” he says.

And here’s a worry: “It is possible that the adverse consequences of higher wage floors may be borne by job seekers, rather than current job holders.”

Young people bearing the brunt of a weak economy

Without wanting to be branded a class traitor, I have to admit that we Baby Boomers have enjoyed a rails-run in the race of life.

Most of us had little trouble getting ourselves set up in the jobs market and then the housing market. I look at today’s bright and bushy-tailed youngsters, just starting out in both markets, and don’t envy them one bit (except, of course, their instinctive understanding of the right place to click on a webpage).

(Just to protect my back: those Baby Boomers who were conscripted, or ended up in Vietnam, didn’t have it easy. Nor should those who’ve come after us imagine all Baby Boomers are rolling in it, have never been unemployed, never paid uni fees nor suffered bad luck.)

In the decade since the global financial crisis and the recession we supposedly didn’t have, the supply of people wanting to work has been stronger than employers’ demand for work to be done.

That’s true even though the rate of unemployment never got very high and isn’t all that high today. But a study by Zoya Dhillon and Natasha Cassidy, of the Reserve Bank, confirms what I’ve long suspected: the reason the position overall hasn’t looked so bad is the brunt of the weakness in employers’ demand for labour has been borne by young people leaving school and university.

Whatever you’ve heard in the media, not a lot of workers have been laid off since the shock in September 2008. Employer behaviour has changed, the study confirms. Firms have been less inclined to get rid of people and more inclined to reduce the total amount of hours they’re paying for.

This has become easier for them to do because of their greater ability to employ people on a part-time or casual basis.

On balance, and from an economy-wide perspective, this change of behaviour is an improvement, a shift to a lesser evil. It’s a terrible blow to suddenly lose your job. Better to have some paid work than none.

But the price for this marginal improvement has been paid mainly by the young. Established workers have tended to keep their jobs, but employers haven’t recruited as many people at entry-level. And more of the jobs they’ve offered young people have been part-time.

A new twist on last in, first out.

The result is that education-leavers have had greater trouble – and suffered longer delays – in finding a full-time job suited to their education.

“Over the past decade,” the study says, “increases in the unemployment and underemployment rates for younger people have been twice as large as for the overall labour market. The share of 20 to 24 year-olds that have become disengaged from either study or work has also increased.”

“Younger people” means those aged 15 to 24, though remember that those aged 15 to 19 will mainly be still at school, while many of those aged 20 to 24 will be at university or TAFE.

Some younger people have part-time jobs while still at school, and most higher education students in full-time study also work part-time.

Nothing new or worrying about that. But “in recent years there has been a pronounced increase in the share of 20 to 24 year-olds working part-time who are not studying full-time”.

You’ve heard, no doubt, that while the official unemployment rate has been edging down, the rate of underemployment – people working part-time who want to work more hours – has been edging up (until lately, as we’ll see).

What’s less well known is that underemployment is dominated by younger workers, and it’s they who’ve done most to drive the rate up over recent years. A lot of this would be people finishing uni but having trouble finding a full-time job and taking a part-time job while they keep searching.

In the mid-1990s, about 80 per cent of all bachelor-degree graduates found a full-time job within four months of graduating. By last year, that had fallen to just over 70 per cent – about the same as it got down to during our last severe recession in the early 1990s.

Remember, it’s like a traffic jam. It takes a lot longer than it should, but you do get through eventually.

The most worrying thing is the “NEET rate” – the proportion of younger people who are “not in education, employment or training”. The NEET rate has fallen over the decades as we’ve done better at getting more of our young people into education and training.

But the rate for 20 to 24 year-olds has increased in recent years and is back to where it was in 2005.

The study says prolonged spells of disengagement from the labour market are known to have lasting ill-effects. “Poor labour market outcomes early on not only affect an individual’s future employability, but also have persistent negative effects on lifetime earnings.”

All this says the difficulties younger people are encountering in finding decent full-time jobs are better explained by the economy’s prolonged period of below-par growth since the financial crisis than by the sexier and more frightening explanation that it’s caused by the rise of the “gig economy”.

Which brings me to a little good news. The trend rate of underemployment for all ages has fallen a little to 8.4 per cent over the past year. And the rate of unemployment for younger people has fallen from 12.4 per cent to 11.6 per cent in just the past four months.

Economy’s health requires reform of earlier wage reforms

Can you believe that many economists were disappointed by this week’s news from the Australian Bureau of Statistics that consumer prices rose by only 2.1 per cent over the year to June?

Why would anyone wish inflation was higher than it is? Well, not because there’s anything intrinsically terrific about fast-rising prices, but because of what a slow rate of increase tells us about the state of the economy.

It’s usually a symptom of weak growth in economic activity and, in particular, of weak growth in wages. Prices and wages have a chicken-and-egg relationship. By far the most important factor that pushes up prices is rising wages.

But, as measured by the bureau’s wage price index, wages rose by just 2.1 per cent over the year to March, roughly keeping up with prices, but not getting ahead of them.

We’re used to wages growing each year by 1 per cent-plus faster than prices, but such “real” growth hasn’t happened for the past four years or so (which probably explains why so many people are complaining about the high “cost of living” even when price rises are so small).

It’s important to understand that wages can grow faster than prices without that causing higher inflation, provided there is sufficient improvement in workers’ productivity – output per hour worked – to cover the real increase.

Of late we’ve had that productivity improvement, but all the benefit of it has stayed with business profits, rather than being shared between capital and labour by means of increases in real wages.

I’ve said it before and I’ll keep saying it until it’s no longer relevant: the economy won’t be back to healthy growth until we’re back to healthy growth in real wages. That’s for two reasons.

First, in a capitalist economy like ours, the “social contract” between the capitalists and the rest of us says that the people without much capital get their reward mainly via higher real wages leading to higher living standards.

Second, consumer spending accounts for more than half the demand for goods and services in the economy; consumer spending is done from households’ income, and by far the greatest source of household income is wages.

So, as a general proposition, if wages aren’t growing in real terms, there won’t be much real growth in household income and, in that case, there won’t be much real growth in consumer spending. And the less enthusiastic we are about buying their stuff, the less keen businesses will be to invest in expansion.

Get it? Of all the drivers of economic growth, by far the most important is real wage growth. If your economy’s real wage growth’s on the blink, you’ve got a problem. You won’t get far.

Economists used to believe that real wage growth in line with trend improvement in the productivity of labour was built into the equilibrating mechanism of a capitalist economy. A chap called Alfred Marshall first came up with that idea.

But with each further quarter of weak price and wage increase it’s becoming clearer it was a product of industrial relations laws that boosted workers’ economic power by helping them form unions and bargain collectively with employers.

As has happened in most rich countries, our governments, Labor and Coalition, have been “reforming” our wage-fixing process since the early 1990s by reducing union rights and encouraging workers to bargain as individuals rather than groups.

Trouble is, governments have been weakening legislative support for workers and their unions at just the time that powerful natural economic forces – globalisation and greater trade between rich and poor countries, “skill-biased” technological change, the shift from manufacturing to services – have been weakening the bargaining power of labour.

Whoops. In hindsight, maybe not such a smart “reform”. My guess is it won’t be long before governments decide they need to promote real wage growth by restoring legislative support for unions and collective bargaining.

But how could they go about this? Well, Joe Isaac, a distinguished professor of labour economics at Monash and Melbourne universities and a former deputy president of the Industrial Relations Commission, outlines a plan in the latest issue of the Australian Economic Review.

Isaac proposes four main reforms of the reforms. First, the Fair Work Act should be less prescriptive, giving the Fair Work Commission greater discretion to intervene in industrial disputes, to conciliate and, if necessary, impose an arbitrated resolution on both sides.

Second, the present restrictions on unions’ right to enter workplaces should be eased to allow them to check the payments made to union and non-union employees, as well as to recruit members.

The widespread allegations of illegal underpayment of wages suggest “a serious lack of inspection of pay records” – formerly a task in which unions had a major role. “These breaches in award conditions cannot be discounted as a factor in the slow wages growth,” Isaac says.

Third, legislation against “sham contracting” – employers reducing their workers’ entitlements by pretending those employees are independent contractors – should be tightened.

Fourth, the present procedures and delays before workers are allowed to strike while negotiating new wage agreements should be reduced.

As well, bargaining and striking over multiple-employer or industry-wide agreements should be permitted. As economists long ago established, real wage rises should reflect the economy-wide rate of productivity improvement, not the experience of particular firms.

Industry-wide and multiple-employer agreements allow unions to support people working in small and medium businesses, not just those in big businesses and government departments.

Such bargains are known as “pattern bargaining” and are illegal at present. It’s true that pattern bargaining was pressed and extended to other industries unjustifiably in years past, but the commission should have the power to prevent pattern bargaining where it’s not justified.

Now, many employers may view Isaac’s proposed “reregulation” of wage fixing with alarm. What’s to stop the return of unreasonable union behaviour and excessive wage rises?

Ah, that’s just the point. What will prevent it is all those other developments that have weakened workers’ bargaining power.

How our economic prospects turn on wage growth

You know the world's behaving strangely when you hear a heavy from the central bank saying it's expecting more "progress" on the "turnaround in inflation", then realise they're hoping inflation will go higher.

That's just what Dr Luci Ellis, the Reserve Bank's third heaviest heavy, told a bunch of economists at a conference this week.

Why would anyone hope for prices to be rising faster than they are? Not so much because higher prices are a good thing in themselves, as because rising inflation is usually a sign of an economy that's growing strongly and keeping unemployment low.

By contrast, very low inflation – say, below 2 per cent – is usually a sign of an economy that's not growing strongly, with unemployment either rising or higher than it should be.

Ellis' remarks are a reminder that the economy's biggest problem at present is weak growth in wages. She knows that if prices started rising faster, the most likely explanation would be higher growth in wages, which employers were passing on to their customers by raising their prices.

What could oblige employers to increase the wages they pay? Their need to retain or attract more workers – particularly skilled workers – at a time when the demand for labour was rising, caused typically by increased demand for the goods and services businesses were employing people to produce.

The point to note here is that the Reserve's mental model of inflation is of what economists used to call "demand-pull" inflation. It's simple: the prices of goods and services rise when the demand for them is outpacing their supply.

Note, too, that this involves an inverse relationship between inflation and unemployment: when one goes up, the other goes down, and vice versa. Economists call this the "Phillips curve", named after its discoverer, Bill Phillips, a Kiwi economist.

Ellis confirmed that, although the economy (real gross domestic product) grew at a trend rate of just 2.4 per cent over the year to September, the Reserve's forecast that growth will pick up to about 3¼ per cent over this year and next remains unchanged.

This will involve a pick-up in wage growth and inflation, she said.

The Reserve is more confident of these forecasts than it was when it first made them in early November. Even so, Ellis admitted to some particular "uncertainties": how much production capacity in the economy is going spare at present, and how much, and how quickly, wage growth and inflation will pick up as spare capacity declines.

How much unused production capacity remains in the economy matters because, until it's used up, the economy can grow much faster than it can once the economy's at full capacity – full employment of labour and capital – without this causing inflation pressure to build.

Once the economy is at full employment, how fast rising demand can cause the economy to grow without also causing higher inflation is determined by the economy's "potential" growth rate – that is, by the rate at which rising participation in the labour force, increasing investment in capital equipment and improving productivity are adding to the economy's ability to produce more goods and services.

That is, how fast potential supply is growing. So the economy's potential growth rate sets the medium-term speed limit on how fast demand can grow before causing a build-up in inflation.

The Reserve's most recent estimate is that our potential growth rate has slowed to 2.75 per cent a year (mainly because of the retirement of the bulge of baby boomers).

But how do we measure how much spare production capacity we have at any time? We measure the spare capacity of our mines, factories and offices mainly by looking at answers to questions in the regular surveys of business confidence.

That's physical capital. In the labour market, idle production capacity is measured by the rate of unemployment.

But it's wrong to think full employment is reached when the unemployment rate falls to zero. That's partly because, at any point in time, there will always be some workers moving between jobs (called "frictional" unemployment).

Also because of a much higher rate of "structural" unemployment. The structure of the economy is always changing, with some industries expanding and some contracting. This increases the number of workers who don't have the particular skills employers are seeking, or who do have them but live far away from where the job vacancies are.

In the old days, there were a lot of low-skilled jobs that could be filled by people who had left school early and hadn't learnt much. These days, there a far fewer of those jobs, so people with inadequate skills are often out of a job.

Economists measure full employment by estimating the rate to which unemployment can fall before shortages of skilled labour cause employers to bid up wages and thus cause price inflation to accelerate.

They call this the NAIRU – the non-accelerating-inflation rate of unemployment – and the Reserve's latest estimate is that it's "around 5 per cent". It says "around" because every economist's estimate is different, so it's wrong to be too dogmatic.

This week's trend figures from the Australian Bureau of Statistics for the labour force in January show the unemployment rate has been steady at 5.5 per cent since July. That's well above the NAIRU.

Over the same six months, however, employment has grown by almost 180,000, or 1.5 per cent, causing the rate at which people are participating in the labour force to rise by 0.4 points to 65.6 per cent – its highest for seven years and a record high for participation by women.

If the laws of supply and demand still hold – a safe bet – this unusually strong growth in the demand for labour should lead to higher wages and then higher prices sooner or later. But Ellis warns it's likely to be "quite gradual".

Seeking the truth about the extent of unemployment

So, the Australian Bureau of Statistics told us this week, the rate of unemployment fell a tick to 5.6 per cent in July. Trouble is, most people know the official unemployment rate understates the extent of the problem.

What many people don't know, however, is that when you take the rate of unemployment and add the rate of under-employment, which in May took us up to 14.5 per cent, you overstate the extent of the problem.

It's well known by now that the official definition of unemployment is a very narrow one because you only have to do one hour's work in a week to be classed as employed.

A lot of people also know – or think they know - that this amazing definition was introduced by the government some years ago to stop the figures looking so bad.

Labor voters know it was a Coalition government that fudged the figures; Liberal voters know the villain was a Labor government.

Sorry, this is an urban myth. It is just not true. The bureau would never allow any bunch of politicians to fiddle with the definitions it uses.

As it has explained many times, the bureau uses internationally agreed standards to define unemployment, which are set by the International Labour Organisation, part of the United Nations.

They had to draw the dividing line between unemployed and employed somewhere, and they chose one hour – a choice that was easier to make in the days when almost all the jobs were full-time.

Even today, there'd be very few people actually working just an hour or two a week. Most would work at least one shift of seven or eight hours.

Even so, there's no denying that such a narrow definition understates the extent of joblessness. This is why the bureau also publishes a measure of underemployment.

The underemployed consist of all those people who are working part-time – defined as less than 35 hours a week – but would prefer to be working more hours.

When you take the rate of underemployment and add it to the rate of unemployment (with both unemployment and underemployment expressed as proportions of the labour force) you get what the bureau calls the "labour underutilisation rate", which we can think of as a broader measure of unemployment.

If you look over the years, the rate of unemployment tends to go higher and lower in line with the downs and ups in the business cycle.

You can also see the business cycle reflected in the rate of underemployment, but it has a much clearer underlying upward trend. It was 2.6 per cent in 1978, but 8.3 per cent in November 2015 and 8.8 per cent this May.

Until early 2003, the unemployment rate was higher than the underemployment rate, but since then the underemployment rate has been higher, with a growing gap.

Between February 2015 and this May, the unemployment rate fell by 0.5 percentage points, whereas the underemployment rate rose by 0.3 points.

The underemployment rate is a lot higher for females, 11 per cent, than for males, 6.9 per cent.

It's also greatest among people in lower-skilled occupations and lowest among people in higher-skilled occupations. (Uni students please note.)

Now get this: although workers of all ages suffer underemployment, it's much more a problem for the young. More than a third of the underemployed are aged 15 to 24, and their rate is 18.5 per cent.

But why has the trend rate of underemployment been rising steadily since the late 1970s?

Since underemployment is an affliction of part-time workers, the steady rise in part-time employment over that time – so that it now accounts for about a third of all jobs – does much to explain why there's more part-timers who happen to be saying they'd prefer to be working more hours.

Professor Jeff Borland, of the University of Melbourne, adds that "younger workers appear to have experienced the largest increase in underemployment because they have had the largest growth in part-time employment".

He reminds us that more young people have part-time work because more of them are in full-time education and needing a part-time job.

But here's my punchline: although the official unemployment rate understates the size of the problem, just adding the underemployment rate goes to the other extreme of exaggerating it.

Why? Because it adds apples to oranges. We worry most about underemployment because we assume it involves people who need full-time jobs but have had to settle for part-time.

It does. But it also includes people who are happy to stay part-time but, even so, would prefer to work an extra shift or maybe just a few more hours.

It doesn't make sense to add people with such a small problem to people with the much bigger problem of needing a full-time job but not being able to find one, as though they were similar.

Remember, too, that almost a third of the people included in the official unemployment rate are looking only for part-time work.

This is why, if you search very deep on the bureau's website (clue: catalogue no. 6291.0.55.003, table 23b) you find that, as well as just counting heads, it also does a more accurate measure of underemployment that counts the hours people are looking for – meaning part-timers needing a full-time job count for a lot more than those just wanting a few more hours.

This "volume" measure shows that, in May, the underemployment rate was 3.2 per cent of all the potential hours the whole labour force could work, and the unemployment rate was 4.3 per cent, giving an hours-based measure of labour underutilisation of 7.5 per cent.

Which is closer to the truth of the matter.

Why wage growth will strengthen before long

It's become deeply unfashionable to presume any of the present weakness in wage growth is merely cyclical (and thus temporary) rather than structural (and thus lasting). Sorry, my years of economy-watching tell me it's never that simple.

It's the mark of an amateur – a journalist who prefers sexy stories to boring stories that are more likely to be true; a youngster who believes all they're told on social media – to believe the established patterns of the past have no bearing on the present.

Note, I'm not denying the likelihood that a significant part of the problem may arise from deep, structural causes requiring correction by judicious government intervention.

What I'm saying is it's far too soon to conclude no part of the weakness is temporary. We'll know the truth of the matter only with hindsight.

We know the importance of "confidence" in driving the business cycle, but it doesn't just apply to businesses and consumers. It also applies to workers negotiating pay rises.

There's a chance that, with all the union movement's exaggerated talk of an ever-rising tide of "precarious employment", organised labour has spooked itself into accepting lower pay rises than it needs to.

As Reserve Bank governor Dr Philip Lowe keeps hinting, one day workers will decide to contest bosses' claims that they couldn't possibly afford more than a 2 per cent pay rise.

For another thing, it's surprising the wage-rise pessimists have failed to take heart from the Fair Work Commission's decision in June to raise not just the national minimum wage, but the whole structure of award minimums, by 3.3 per cent.

This compares with a rise last year of just 2.4 per cent.

It's true that only about a quarter of employees are directly affected by this decision, but many more are affected indirectly because the "individual arrangements" by which their wages are set consist merely of a set margin above their award rate.

And why would the supposedly more industrially powerful workers on enterprise agreements settle for another 2 per cent rise when, all around them, weaker workers were getting 3.3 per cent?

But there's a more technical argument that a period of weak wage growth was just what was needed as part of our transition from the decade-long resources boom. With that transition close to completed, it shouldn't be long before wage growth strengthens.

As Professor Ross Garnaut warned in 2013 in his book, Dog Days, the big fall in the nominal exchange rate that (eventually) followed the collapse in mining commodity prices wasn't all that was needed to restore the international price competitiveness of our export and import-competing industries.

We also needed the nominal depreciation to become a "real" depreciation, with the costs faced by Australian firms rising much more slowly than the average of costs faced by firms in our major trading partners' economies.

Garnaut doubted we could achieve the high degree of wage restraint need to make the depreciation stick but, as former top econocrat Dr Mike Keating pointed out in a recent blog post, that's just what's happened.

Keating says you'd expect that, over the medium to longer term, real wages, the productivity of labour and "real net national disposable income" per person (a version of gross domestic product that's adjusted for swings in our terms of trade) would each grow by about the same amount.

Between 2002 and 2012, the period of the resources boom, real wages grew faster than productivity, though by less than the strong growth in the real national income measure.

But Keating notes that, following the 2012 peak in the resources boom, these relationships were reversed, with real national income actually falling between 2012 and 2016. Real wages then needed to rise by less than productivity, which is just what's happened.

"My judgement is that equilibrium between productivity, [real] wages and real net national disposable income per person has now been restored," Keating concludes – implying there's now scope for real wages to grow in line with improvements in productivity.

This fits with the Reserve Bank's conclusion in its May statement on monetary policy that, as measured by comparing our "nominal unit labour costs" (nominal wage growth versus the change in labour productivity) with those of our trading partners, our real exchange rate has fallen to about its post-float average. This wouldn't have changed much since May.

So there's been a sound economic justification – the need to restore our industries' international price competitiveness – for our weak wage growth over the past three or four years.

But that need has now been satisfied, allowing us to hope for a return to real wage growth.

The way wages are set is changing

Since we've all got so excited about the weak growth in wages, let me ask you a personal question: How much do you know about how wages are set?

For instance, how many workers are affected by the 3.3 per cent increase in the federal minimum wage, announced by the Fair Work Commission in June?

Some people say the weak wages growth is explained by the efforts to discourage collective bargaining under John Howard's Work Choices and neo-liberalism more generally. Any signs of this?

Wages can be set in different ways. So what are they, and how many workers are affected by each?

These questions are answered by a box on the minimum wage decision in the Reserve Bank's latest statement on monetary policy, issued last week. Many of its figures came from the Australian Bureau of Statistics publication, employee earnings and hours, catalogue number 6306.0, for May 2016.

The bureau finds three main ways of setting the wages of employees: "award only", collective agreements and individual arrangements.

Industrial "awards" are legally enforceable determinations made mainly by the federal Fair Work Commission, which set the minimum pay and conditions for employees in a particular industry or occupation.

They form a safety net for the great majority of employees. Any employer paying less than the minimum wage specified in the relevant award is breaking the law and could be prosecuted.

Every year the commission reviews, and usually increases, the "national minimum wage", which is the lowest amount any adult employee may be paid. In this year's review, the national minimum was increased by 3.3 per cent to $18.29 an hour.

What's less well understood is that, at the same time it adjusts the national minimum wage – the minimum minimum, so to speak – the commission also adjusts all the various minimums for workers in different classifications set out in each of the many industrial awards.

Since 2011, the commission has increased the full set of award minimum wages by the same percentage as its increase in the national minimum wage.

According to the bureau's latest figures, for May last year, about 23 per cent of our 10.1 million employees were totally reliant on the relevant minimum wage set out in their award.

Next on the list of wage-setting methods is the 36 per cent of employees whose wages are set by "collective agreements".

Most of these agreements are "enterprise bargaining agreements" negotiated with employers by a union representing the workers at the enterprise.

Enterprise agreements – which should be registered with the commission – build on the provisions of the employees' award, usually involving wage rates and conditions (such as paid leave) that are more generous than provided for in the award.

That leaves 41 per cent of employees – the largest share – having their wages set by "individual arrangements". But this is a rag-bag group.

It may include some people still on formal "individual contracts" left over from the Work Choices era, and it certainly includes managers and employees in highly paid professions whose wages and conditions have always been set by direct negotiation with the boss.

But there's another, big and interesting group: all those ordinary workers whose "individual arrangement" is that they get the award wage plus $X a week, or plus Y per cent.

This means a lot more workers' pay is protected by the award system than a quick look at the figures would suggest. Similarly, the commission's annual increase in award wage rates has a bigger effect on overall wage growth than you'd think.

So how have the proportions of employees in the three wage-setting categories been changing?

Over the 14 years to the start of 2016, the share of employees covered by collective agreements has fallen by 1.8 percentage points to 36 per cent, while the share of individual agreements has fallen by 0.4 points to 41 per cent, meaning the share of award-only employees has increased by 2.2 points to 23 per cent.

But before you take this as proof that a campaign against collective bargaining has forced more workers back to mere reliance on their award, remember there are other possible explanations.

Changes in the composition of the workforce, for instance. Since most part-time employees are award-only, the slowly increasing proportion of part-time jobs could explain much of the increase in the award-only share.

And remember this: some industries are growing faster than others, but different industries have different degrees of reliance on particular wage-setting methods.

For instance, collective bargaining is most common in public administration (covering 78 per cent of employees), education and training (63 per cent), utilities (60 per cent), and health care (55 per cent). That is, industries dominated by the public sector.

Individual arrangements are most common in professional and technical services (80 per cent), wholesale trade (70 per cent), rental and real estate services (63 per cent), construction (58 per cent) and – get this – manufacturing (55 per cent).

That leaves the award-only method most common in hospitality (43 per cent), admin services (42 per cent) and retailing (34 per cent).

It's true that hourly rates of pay are highest for employees with collective bargaining ($39.60), with individual arrangements next on $38.50, and award-only last on $29.60.

But the gap has been narrowing, with the average hourly rate under collective bargaining growing by 89 per cent in nominal terms over the 16 years to May 2016, while award-only grew by 97 per cent and individual arrangements by 109 per cent.

Again, however, this is likely to be explained more by the changing structure of industries and occupations – for instance, a higher proportion of high-paid managers and professionals in the individual arrangements category – than by campaigning against collective bargaining.

Statistics – especially these broad averages – can be misleading. But ignoring the stats and listening only to anecdotes will leave you with a much more distorted picture of reality.

All the things that aren't causing weak wage growth

There's just one problem to remember before we work ourselves into a complete tizz over the War on Wages, convincing ourselves globalisation and digital disruption mean we'll never get a steady job or a decent pay rise again.

It's this: so far we've heard a lot of suspiciously confident predictions about the way robots and digitisation are about to destroy millions of jobs, a lot of anecdotes about law-breaking employers, a lot of scary stories about "the gig economy" and "portfolio jobs", a lot of adults assuring impressionable school children they'll have 10, or is it 17, different jobs in their working lives, a lot of propagandising by the unions about the rise of "precarious employment" and a lot of speculation about how all this somehow explains why wages growth is the slowest it's been since the early 1990s.

Know what we haven't got a lot of? Hard evidence that any of all that has actually started happening to any significant extent.

This is not to say some version of all that won't happen at some time in the future. I can't say it won't since I don't know that the future holds, unlike all the self-proclaimed experts with their precise predictions.

(Next time you hear someone telling you exactly how many jobs robots will have destroyed by 2020, or how many jobs or occupations you'll have in the next 40 years, ask yourself this question: How – would – they – know?)

But if there's no evidence this frightening future has got going yet, there's no way it can explain why wage growth has been so weak for the past three or four years.

For once, let's take a close look at what we actually know has been happening.

It is true that, as we saw in this column two weeks ago, the structure of occupations in the workforce is changing. Research by Dr Alexandra Heath, of the Reserve Bank, shows the share of routine jobs has fallen by 14 percentage points, while the share of non-routine jobs has risen by 14 points.

Similarly, the share of manual jobs has fallen by 5 percentage points, while the share of cognitive jobs has risen to the same extent.

But this is a long-term trend. These figures are for the change over the 30 years to 2016, and there's no sign of the trend accelerating over recent years.

A lot of detailed – and reassuring – research on the official statistics has been done by one of our leading labour-market economists, Professor Jeff Borland, of the University of Melbourne, and reported on his website, Labour Market Snapshots.

For one thing, Borland's been searching for evidence that our jobs are being taken by robots – and failing to find it. He breaks the issue into two parts.

First, has computerisation reduced the total amount of work needing to be done by humans, as many people assume?

No. The total amount of work available per head of population has bounced around with the ups and downs of the business cycle but, overall, has shown no downward trend. The latest figures show, if anything, a bit more hours of work per person than there were in the mid-1960s.

Second, consistent with Heath's research, Borland finds evidence that the progressive introduction of computers, which began in the early 1990s, is probably changing the types of jobs being done by workers.

But he, too, finds that the pace of change in the composition of employment "is no quicker today than in the period before computers".

"So while computers may be having some impact on the Australian workplace, most claims about their impact are vastly overstated," Borland concludes.

Next, Borland shines his statistical spotlight on all the claims about work becoming more insecure or "precarious".

You don't have a proper, full-time permanent job. You get a bit of work here and a bit there. If you do have a job, it never lasts long.

The Australian Bureau of Statistics has long published figures for job "tenure" – how long people have been with their current employer.

If all the talk of growing instability was a genuine trend – as opposed to the experience of a relatively small number of individuals – you ought to be able to see it in the job tenure figures.

But you can't. The reverse, in fact. Borland finds that, from the early 1980s to the present, the proportion of workers who've been in their job for 10 years or more has been steadily increasing. This is greatest for women, for whom it's gone from 12 per cent to 25 per cent.

At the same time, the proportion of all workers in their job for less than a year has been decreasing.

Next, how insecure do workers feel? When the bureau asks employees whether they expect to be with their present employer for the next 12 months, the proportion of men who don't has been steady at about 9 per cent between May 2001 and May this year.

Over the same period, the proportion for women has fallen steadily from 11 per cent to 9.5 per cent.

From all the talk, you'd expect the proportion of employees working for labour hire companies and temporary agencies to be rising strongly.

It ain't. Actually, between 2001 and 2015 it's fallen from a tiny 3.1 per cent to a tinier 2.2 per cent.

And though it's true the proportion of jobs that are part-time is continuing to rise, over the 10 years to 2016 it rose at the slowest rate for any decade since the mid-1960s.

Of course, none of this is to deny that wages growth in Australia has been surprisingly weak for several years, as it has been in other developed economies.

But in our guessing game about what might be causing that weakness, let's not get too fanciful.

Occupations are changing as the jobs total grows

Have you heard that most of the jobs being created in the economy these days are part-time? No? Good. Yes, you have? Sorry, your info's out of date.

It was true last year, but not this year. As this week's figures for the labour force from the Australian Bureau of Statistics showed, of the 176,000 additional jobs created in the first six months of this year, 93 per cent were full-time.

That, BTW, was an exceptionally rapid annualised rate of growth of 2.9 per cent. Doesn't sound like the economy's dead yet.

Admittedly, it was a very different story last year. The calendar year saw growth in total employment of just 100,000 jobs – a very weak 0.8 per cent – of which 135 per cent were part-time.

Huh? Think about it: there must have been a fall of 35,000 in the number of full-time jobs. And there was.

It was a particularly bad year, and with all the happy scare stories about the rise of the "gig economy" it was enough to convince a lot of education-leavers that their chances of ever getting a decent, full-time job were low.

Moral: don't count your nightmares before they've hatched.

Dr David Gruen, a deputy secretary in the Department of Prime Minister and Cabinet, noted in a speech this week that "the displacement of jobs by technology ... is one of the developments that is leading to a sense of unease among many in the community."

People may fear that their own job may be taken over by a machine, or worry there'll be insufficient meaningful jobs for their kids.

Maybe, maybe not. Before we leap to cataclysmic conclusions, Gruen reminds us that fears of technological advances rendering many jobs obsolete is an idea with a long pedigree – back to the Luddites going around smashing machines in the early 1800s.

In the 200 years since then, employers have never ceased seeking out the newest and best labour-saving technology, but so far this has failed to cause mass unemployment.

Coming to today, Gruen says there's little sign of a quickening in the rate of change in occupations that might signal big, new technology-driven changes in the labour market. Nor is there any sign of the rapid improvement in the productivity of labour that you'd expect to see if there was widespread replacement of workers with machines.

But what's been clear for some time, he says, is that jobs across the economy are not equally susceptible to being displaced by technology and automation.

"Routine or predictable tasks are more susceptible to displacement than non-routine tasks. This observation applies to both manual and cognitive tasks – whether manual or cognitive, routine tasks are easier to automate than non-routine ones."

Dr Alex Heath, of the Reserve Bank, has used the stats bureau's figures on workers by occupation to see how these distinctions have affected our workforce over the 30 years to 2016.

She finds no sign of a recent quickening in the pace of change in occupations, but she certainly does find such change over the 30 years since 1986.

The proportion of routine manual jobs (such as labourers and machinery operators) in total employment has fallen from 40 per cent to 30 per cent, while the proportion of routine cognitive jobs (such as salespeople and clerical workers) has fallen from 27 per cent to 24 per cent.

In contrast, the number of non-routine manual jobs (such as nurses and hospitality workers) has risen from 6 per cent to 11 per cent, with non-routine cognitive jobs (such as management and professional occupations) rising from 27 per cent to 36 per cent.

This means routine jobs' total share of the workforce fell by 14 percentage points, whereas non-routine jobs' share rose by 14 points.

The share of routine and non-routine manual jobs fell by 5 percentage points, meaning the share of all cognitive jobs rose by the same.

(If you're wondering, over that 30-year period, total employment grew by almost 5 million jobs – an increase of more than 70 per cent – with the extra jobs spread about equally between part-time and full-time.)

Gruen says we should expect these trends to continue. But he makes a point first made by American economist Daron Acemoglu, that there's not one big trend going on in the workplace, but two.

The one that gets all the headlines is automation – jobs being taken over by machines. But the trend that gets much less notice – thus contributing to the public's excessive anxiety – is the continuous creation of new, useful, complex (that is, non-routine) jobs.

We've seen that, for at least the past 30 years in Oz, both trends have been at work. One displacing jobs, the other creating them. And so far, their effect on the composition of jobs has been roughly equal, and hasn't prevented continued growth in the total number of jobs.

Of course, it remains possible that the digital revolution will cause an acceleration in trend of displacement of jobs by machines, thus overwhelming the creation of new, complex jobs.

But another American economist, David Autor, has explained that certain tasks are particularly hard to automate.

These are tasks "that people understand tacitly and accomplish effortlessly, but for which neither computer programmers nor anyone else can enunciate the explicit 'rules' or procedures ... [The] tasks that have proved most vexing to automate are those demanding flexibility, judgment and common sense – skills that we understand only tacitly".

Of course, it's possible that "machine learning" may overcome these problems, but there's another constraint on machines taking all our jobs away to remember: the need for interpersonal skills in a growing number of jobs, plus our human preference for being served or helped by humans, not robots.

Don't discount the human factor.

How politicians use claims about 'jobs' to mislead us

What's the four-letter word politicians of both stripes most use to bamboozle voters? Jobs. Or, as Neville Wran, former NSW premier and never given to understatement, used to say Jobs, Jobs, Jobs.

Economists and business people worship at the shrine of Growth because it raises their material standard of living. Materialism is the god of our age.

But growth is rarely what the pollies try to sell the public on. No, what presses the right button with ordinary folk is jobs.

Just as most of us don't know much about art, but know what we like, so most of us don't know much about economics, but do know there's an eternal shortage of jobs. We can just never hope to have enough of them.

So the sleaziest, most obviously self-aggrandising business person knows to say about whatever money-making project they want permission to undertake that it will create loads and loads of new jobs.

No matter what damage your scheme would do to the surrounding environment – and thus to the prospects of other industries – nor how great the risk you'll skip town if it's not working out, promise jobs and you're already half way in the door.

You can always find a friendly economic consultant who, for a small consideration, will do some modelling of your proposition and produce a generous – even exaggerated – estimate of the many thousands of jobs your plan will generate. Directly and, not forgetting, indirectly. Thousands.

Then there's a high chance government politicians will take up your cause, accepting without question or qualification you inflated job estimates, and castigating all those who lack the vision to see how much your scheme will contribute to the community's wellbeing (not to mention their re-election).

This, among many other instances, is the story of the resources boom, which our leaders applauded all the way and made little effort to control.

Think of all the jobs created. The main price we paid was that the dollar, caused by the boom to stay way too high for too long, prompted a slab of our manufacturing sector to give up the struggle.

Perversely, the highly-publicised loss of jobs that followed has served only to reinforce the public's conviction that we can never have enough jobs and that anyone claiming to want to create a few should be welcomed without further question.

It's true, of course, that a healthy rate of growth in employment is the most important thing we should expect of our economy, given our growing population.

Trouble is, our uncritical obsession with jobs – any jobs – leaves us open to manipulation by business people and politicians with their own barrows to push.

Promoters of projects exaggerate the number of jobs they will create secure in the knowledge that politicians and the media will repeat their claims without bothering to check them.

And no one but no one will return a few years later to check the gap between what was promised and what was delivered.

With mining projects, too little is done to remind people that almost all the promised jobs are for the construction, not running the thing. As soon as the project's completed, the construction workers go back where they came from – often overseas – leaving the nearby towns as flat as a tack.

Many development projects require skilled workers. But workers with particular skills are usually in short supply, meaning the project doesn't create additional jobs for plumbers or whatever so much as create vacancies that have to be filled by attracting plumbers away from their existing jobs elsewhere.

Every dollar anyone spends has indirect, flow-on effects beyond what was originally spent on. But these indirect effects are hard to measure and easy to exaggerate.

My rule of thumb is that whenever you hear the promoters of projects talk about all the jobs to be created indirectly, they ain't to be trusted.

As you recall, the centrepiece of Malcolm Turnbull and Scott Morrison's "plan for jobs and growth" was their desire to cut the rate of company tax from 30 to 25 per cent over 10 years.

Last week the Senate agreed to cut the rate to 27.5 per cent for companies with turnover under $50 million a year.

Turnbull and Morrison have chosen to regard this a big win, and are already assuring us it will do wonders to encourage small and medium businesses to expand and create jobs.

ScoMo​'s demanding to know whether Labor would reverse the tax cut and spend the money on other things, such as education and health, accusing it of "playing cynical politics all along with no regard for the jobs and wages that are at stake".

Get it? Cutting company tax creates jobs; not cutting it doesn't. Nor does spending the money on education and health create jobs.

This is economic nonsense. ScoMo regards it as a self-evident truth that cutting taxes creates jobs whereas raising taxes destroys jobs. Unfortunately, no one's told the Scandinavians.

In fact, there's no empirical evidence of a relationship between countries' level of taxation and their success in creating jobs.

ScoMo's own Treasury modelling predicts that the full company tax cut would do almost nothing to increase employment.

Beware of politicians trying to sell propositions on the basis of all the jobs they'll create. They just know which of your buttons to press.
