Occupations are changing as the jobs total grows
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.

ETHICS IN ECONOMICS
Australian Conference of Economists, Special Session, Sydney, Friday, July 21, 2017
The notion that ethics has anything to do with economics, that economists should subject their professional behaviour to some sort of ethical standard, is such a foreign one that we have a long way to go in just accepting the idea, let alone finding a way to put it into practice.
I don’t pretend to have all the answers, though I do have some strong opinions. And it probably won’t surprise you to know that, as a journalist, my work is subject to a clear and detailed ethical code, set by the journalists’ union, accessible on its website, endorsed by many media companies and updated as necessary. Journos don’t delude themselves that they merely explore a “positive” science, without resort to “normative” considerations.
There are two ways to think of the economists’ role. One is that it’s to provide the community with dispassionate advice about the best ways for it to go about achieving its economic objectives. The other is to explain/convince/assert to the community what its economic objectives should be, and hence the policies that must be followed to achieve them.
The term “economic rationalism” was in use long before the sociologist Michael Pusey took credit for coining it, but the growing influence of this Treasury-style thinking during the term of the Hawke-Keating government – the Australian equivalent of what people overseas call neoliberalism – was very much in this second, more missionary approach of telling governments exactly what policies they should and should not be following.
In my own career as an economic commentator it wasn’t until around the turn of the century that I found my own ethical anchor in the slogan, Serve the Reader. Although I haven’t stopped supporting those policies I consider to be better than others, I have switched my mission from trying to persuade readers of the rightness of the economic rationalist cause, to acting as a kind of theatre critic to economics, elucidating the strengths and weaknesses of economic theories and policies for the benefit of my readers. When I see someone – politician, vested interest, economist – using economics to pull the wool over my readers’ eyes, I’m on their case.
Which brings me to the main point I want to make and the main reason I was so easily enticed to be on this panel today. If ever there was a part of the economics profession where behaviour seems most in need of ethical standards it must surely be the relatively new industry of “economic consultancy” – economists who make their living providing economic analysis – usually in the form of econometric modelling – to paying customers, usually industry groups lobbying the government for or against some policy proposal, but occasionally the government itself.
Sometimes I think economic consulting is little more than the up-market end of the public relations industry. I suppose there must be occasions where these consultants provide their clients with analysis purely for their use internally but, for the most part, the analysis is sought so that it can be made public, complete with oversimplified press release, in order to influence public opinion and put pressure on the government.
Often the attempt is made to give this analysis greater authority and credibility by calling it “independent” analysis. I can’t remember ever hearing the economists who produced it contradicting this claim, but nor can I imagine how anyone who believes in the power of market forces could believe that analysis that’s the product of a commercial transaction – where the producer is hoping the paying customer is pleased with what they paid for and will make repeat orders – is in any way “independent”. Is it the behaviour of an independent authority to keep its mouth tightly buttoned while your client, and the politicians who agree with his cause, repeatedly misrepresent your findings to the public?
This lack of independence is just as much the case when Treasury or some other department is commissioning analysis on behalf of the government. Sometimes the government may be genuinely uncertain and in need of external advice, but it’s far more likely it’s after “modelling” intended to help it persuade the public and the Senate that the policy it has determined to introduce should be accepted. In such transactions, Treasury knows what policies it favours, it knows what the government wants to be told, and it has a fair idea which consultants will be more amenable to giving it and its political masters the advice they’re hoping for. Forum shopping is a vice not limited to lawyers. Why do you think successive governments have refused to allow the Productivity Commission to analyse the costs and benefits of the so-called free trade agreements they make? They know the trouble with the PC is that it really does consider itself independent.
You don’t need to be a modeller to know how easy it is for the modeller to get the results desired by the choice of model used and by tweaking the variables. And yet the results are so often presented to the public as though they are God’s immutable truth. There’s no accompanying acknowledgement of the chosen model’s strengths and weaknesses, no admission of the key variables that are driving the models results, no sensitivity analysis, no admission that the model is a combination of both empirically measured variables and mere economic theories about how the variables combine to produce the model’s much touted results. No admission that exogenous variables for the future are set quite subjectively. No admission that many economists would disagree with the particular theories underlying the model you used.
Sometimes cannier modelers seek to insure themselves against criticisms such as these by burying in the very fine print of their reports jargon-ridden acknowledgements of some of them. But they stay mute when their results are presented and debated in a way that makes clear these insurance clauses haven’t been read by the very people who should have read them, as it was always intended they not be. This is ethical behaviour? Caveat emptor makes it all OK?
But I suspect there’s a related, less commercially driven reason why the use of economic modelling in the public policy debate is more about bamboozling non-economists than enlightening them. The other explanation is that, consciously or unconsciously, economists seek to avoid the Wizard of Oz Moment, when we see behind the curtain and realise the powerful wizard is really just a little man shouting into a megaphone, using tricks to make out he knows a lot more than he actually does.
Consider just two examples. Although many economists bang on endlessly about the adverse incentive effects of high marginal tax rates, we purport to show the effects of major tax reform using a model that can represent income tax only as a flat-rate tax. Why? Because it has just a single, “representative” household. We use a model utterly inadequate to the task – because it’s the best we’ve got – and present the results as definitive without any up-front admission that we don’t have the tools to answer the question we’ve been asked.
Or, take the very common modelling practice of assuming a short-term Keynesian world and a long-term neoclassical world. We ask such a model to tell us the long-term economic cost of introducing the carbon pollution reduction scheme. It starts in equilibrium, introduces the disturbance of a CPRS, wobbles a bit, then starts on its inexorable journey back to long-term equilibrium. Then we announce to the punters that our modelling shows the scheme’s long-term cost in forgone economic growth is, fortunately, quite minor. Then we wonder why they don’t trust us.
They say forecasters have a lot to be modest about. I’d add they have a lot to be more ethical about.

The era of neoliberalism is ending and reversing
I'm a great believer in the pendulum theory of history: trends in human activity go on and on until they reach an unacceptable extreme, and then one day they turn and start going back the way they came.
That's certainly the way fashions in economics and government policy work. Consider the story since the end of World War II, using Britain as our guide.
There was a great reforming spirit after the war, and much that needed fixing. The economy wasn't working well and ordinary people – who'd done their duty so selflessly during the war – weren't getting a fair share of the economic rewards.
So the Brits set about installing the welfare state – comprehensive social security payments and a national health service in which most doctors became government employees – and "nationalising" many troublesome but important industries.
This new trend of nationalisation was copied in other countries including, to an extent, Oz.
But as the years rolled by it became clear that Britain's economy wasn't working well. Eventually, a new Boudica rose up, name of Maggie Thatcher, to set things right.
The problem was obvious: too much of the economy owned and run by the government and all those civil servants. Too many rules and regulations. The economy was inflexible and unresponsive. The unions had too much power and were abusing it, always on strike until they got their way.
The answer was to "privatise" most of the nationalised industries and get the unions back in their box.
We need to unshackle the power of the market, with its much greater ability to respond to changing times, greater desire to satisfy customers' needs and motivation to root out inefficiency.
This new trend of privatisation and deregulation – also pushed by Ronald Reagan in the US – has been copied in many developed economies, not least here.
By the early 1980s our economy wasn't working all that well. In a world of floating currencies, we were still trying to fix our exchange rate, battling speculators who always won.
Our banks were a joke, never able to lend enough for a home loan, so you went to a building society or they fitted you up with an expensive second mortgage from their finance company.
We'd been trying to cut ourselves off from the world with high barriers against imports, but been left with an economy that was highly inflation-prone, with much higher unemployment to boot.
Paul Keating and Bob Hawke set about modernising the economy, opening it up to a rapidly globalising world. They didn't ape Thatcher so much as start listening to the advice Treasury had been giving governments for years.
You've detected history's pendulum at work, I trust. Look at it over the decades and you see the fashion in management of the economy swinging from one extreme to the other.
Why does it swing so far? Because the truth – the happy medium – is somewhere in the middle but, because it's some combination of market forces and government management, is devilishly hard to find.
Much easier and more satisfying to champion one extreme or the other.
Why bring this up now? Because, if you hadn't noticed, this particular pendulum has just started swinging back.
As no less an authority than The Economist magazine has judged, the "neoliberal consensus" has collapsed.
For almost 40 years in the English-speaking economies, both sides of politics have accepted that businesses and individuals should be allowed to go about their affairs with as little restriction as possible.
But now both sides are stepping back from that attitude, doing so under pressure from voters growing increasingly unhappy about the state of the economy – in Oz, low wage growth, high energy costs, a seeming epidemic of business lawlessness and a lengthening list of government outsourcing stuff-ups – and the special treatment accorded to business.
You can see it overseas in the electoral popularity of Bernie Sanders and Jeremy Corbyn, and the anti-establishment revolts in the Brexit vote and the election of Donald Trump.
It didn't do her any good, but you see it in Theresa May's Conservative Party election manifesto: "We do not believe in untrammelled free markets. We reject the cult of selfish individualism. We abhor social division, injustice, unfairness and inequality."
Here, you see it in Malcolm Turnbull's reaction to the failed reform of the national electricity market, with his willingness to impose export restrictions on gas companies, buy Snowy Mountains hydro back from the states and contemplate federal construction of new coal-fired power stations.
You see it in Bill Shorten's policy of curbing negative gearing and the capital gains tax discount, his opposition to cuts in the company tax rate and willingness to legislate to restore and protect weekend penalty rates.
I reckon there's a lot more government assertiveness to come. You don't fancy a lifetime of precarious employment in the "gig economy" for yourself or your kids?
Don't worry, before long governments will legislate to protect employees rights at work – just as they used to in the old days.

Worsening school performance is everyone’s business
Unfortunately, seeing the sense of this is a lot easier than ensuring it happens.
On natural capital – the preservation of species and physical resources, and the healthy functioning of the ecosystem – we've got one whole side of politics still struggling to get its climate-change deniers back in their box.
Even on human capital – the acquisition of knowledge and know-how – there's plenty of conflict, ranging from economic rationalists who think constraining the growth in government spending and taxation more important than accruing human capital, to people in the education system who think the adequacy of their present performance is no one's business but their own.
On the one hand, we've got the smaller-government brigade saying the performance of, say, school education can be fixed without spending an extra dollar.
On the other, we have teachers – some of them, anyway – arguing there's no problem that having taxpayers hand over a lot more bucks wouldn't fix.
How would the extra money be spent? That's for teachers and education departments to decide, and for everyone who isn't a teacher – and therefore knows nothing about schools – to mind their own beeswax.
The smaller-government brigade closes its eyes to the need to improve the performance of our schools and to the significant economic and social gains we stand to make by improving that performance.
The size of these gains can be demonstrated using the Fairfax-Lateral Economics index of Australia's wellbeing, compiled by Dr Nicholas Gruen and published every quarter upon the release of the national accounts.
The index overcomes the limitations of gross domestic product as a measure of economic progress by starting with the most appropriate modification of GDP – real net national disposable income – and adding to it estimates of the value of human capital, natural capital, the effects of distributional inequality, environmental amenity, health and employment-related satisfaction.
The measure of human capital takes account of early childhood risk, school performance, tertiary education, innovation (multi-factor productivity) and skills atrophy from long-term unemployment.
The indicator used to measure our progress in school education is the change in our score from the regular testing of our 15-year-olds' reading ability under the OECD's Program for International Student Assessment.
Our kids' reading score has fallen almost continually since 2000, from 528 to 503, or 4.7 per cent. By comparison, Canada's score has declined only marginally over the period, from 534 to 527.
The index's estimates suggest that, were we able to lift our score only to Canada's level, this would increase the value of our human capital by almost $17 billion a year.
That's equivalent to about 1 per cent of GDP – far more than promised by almost any other proposed economic reform, including cutting the company tax rate.
Putting it another way, had our 15-year-olds' performance not deteriorated since 2003, the estimated value of the human capital – know-how – in the heads of this year's 15-year-olds would be $17 billion greater than it is.
Our kids' academic performance in each of the areas measured in the PISA tests – reading, maths and science – has been deteriorating, though at differing rates. This is worse than the picture shown by successive NAPLAN test results, summarised as flat to down.
This is why teaching is a problem too important to be left to teachers. The more so because some teachers – a minority, I trust – have become hyper-defensive, refusing to acknowledge there's a problem, telling themselves that, if there is a problem, it's everybody's fault bar their profession's, and branding any non-teacher who dares to offer an opinion a "teacher-basher".
Julia Gillard's attempt to use the measurement (via NAPLAN) and publication (via the My School website) of students' and schools' academic performance to raise standards by fostering competition between schools was misguided – pseudo-economic – and has failed.
But too much of the resistance and criticism of NAPLAN and My School arise from some teachers' desire to continue avoiding public accountability for the quality of their work.
It should go unmeasured (because fault can be found with every form of measurement humans have tried) and, to the extent that performance information exists, it should remain confidential to insiders, because outsiders lack the expertise to interpret it correctly.
Sorry guys, but more money comes at the price of greater accountability to, and scrutiny by, the mug taxpayers who cough it up.
