It's official: the labour market is different

Any report that the hardline commentators brand as "mushy drivel" can't be all bad. And, indeed, the Productivity Commissions' draft report on the Workplace Relations Framework is far more enlightened, balanced and sensible than we've come to expect from that highly model-bound institution.

For several years, militant employer groups and the national dailies have been claiming that Julia Gillard's Fair Work Act reregulated the labour market, put the unions back on top and caused the slowdown in productivity improvement.

The report puts those people back in their box, rejecting outright their claim that the industrial relations system has become dysfunctional.

"Many features work well, especially given the need to find a balance between the conflicting goals of the parties involved," the commission's chairman, Peter Harris, said.

"Changes to the workplace relations framework have to recognise that it's not just about the economics. There are ethical and community norms about the way in which a country treats its employees."

The report's conclusion is that industrial relations needs "repair not replacement". So it does propose a lot of changes – most of which go the employers' way – which are worth debating, but not today. Today let's just record the full extent to which the scales have fallen from the commission's eyes.

Its first realisation is that the labour market isn't the same as other markets and labour is not just an ordinary input to the production process.

"Labour economists [those economists who specialise in studying the labour market] generally recognise that labour markets work somewhat differently from the pure competition model. Of course, no market aligns completely with the basic and tractable model described in introductory economic textbooks, and some of the common divergences from the competitive model arise in labour markets too," the report says.

"However, labour markets additionally have some particularly distinctive features. These features provide a potential economic rationale for different aspects of labour market regulation . . ."

What's distinctive about the labour market is that "units" of labour being added to the production process inescapably come with fallible humans attached. What's more, the human units work for fallible human managers. This makes the labour market far less impersonal than textbooks describe.

"In the real world, employers and employees are people with all their various flaws and virtues, and these can collide in workplaces in ways that have ramifications for how labour markets function."

For one thing, "people make mistakes". For instance, employers and employees may form an employment contract without doing enough to check the other side out.

For another, "employers and employees have values that are important to the way they do their work. An employee may want to work many additional hours at no cost because of professional pride. Employers may want to pay bonuses, provide better staff facilities or assist an employee facing family problems (say domestic abuse) because they are dealing with human beings who they wish to help and please.

"Employers and employees dealing with each other are not merely doing so as part of a calculated business strategy, and in some cases this opens the door for one party to exploit the other's goodwill and non-monetary motivations. (One less altruistic formulation of this is that employers may sometimes set higher prices for labour to motivate trust and to increase the cost of shirking – one example of so-called 'efficiency wages'.)"

The simple model assumes units of input and even units of output are homogeneous (all the same). But "there are few 'representative' employers and employees. People have heterogeneous [different] tastes for workplace conditions and heterogeneous abilities, even when paid the same wage rate.

"Some businesses are poorly managed, and most are not at the technological and managerial frontier [not best-practice]."

Some of these complexities "suggest a need for regulation, others not. For example, regulation of blatantly unfair dismissal is justified, not only because the act itself is problematic but also because the potential to do it allows leverage by an employer to exploit vulnerable employees".

The commission "considers that, on average, employers have stronger bargaining power than employees, with consequences for wages and conditions, unless countered by regulations or (constrained) employee collective bargaining".

Get that? The commission acknowledges the legitimacy of collective bargaining. It also accepts the relevance of ethical and social considerations.

"Labour market outcomes do not just affect economic performance – they also have a substantial impact on equality of opportunity, the stability of family relationships and social cohesion more generally.

"The ethical and social dimensions of the labour market form a basis for many aspects of the workplace relations system that differentiate it from the regulation of other markets. For example, the 'price' of labour differs from the price of most other inputs in an economy.

"A broad principle underpinning Australia's competition policy framework is that lower prices from competition are almost always desirable. In labour markets it is less clear that a lower price is necessary desirable, given that many people's incomes and wellbeing depend to a considerable extent on the price of labour and it can be costly to use alternative mechanisms to redistribute income.

"Indeed, the existence of a minimum wage – a 'floor price' set by regulation, which would usually be seen as contrary to the public interest for other goods and services – illustrates this distinction."

Returning to the commission's dismissal of the militant employers' claims, it finds that "contrary to perceptions, Australia's labour market performance and flexibility is relatively good by global standards, and many of the concerns that pervade historical arrangements have now abated.

"Strike activity is low, wages are responsive to economic downturns and there are multiple forms of employment arrangements that offer employees and employers flexible options for working."

But my favourite quote is this: "Toxic relationships between employers and employees can sometimes surface due to poor relationship management rather than flaws in the workplace relations framework."

Ain't that the truth.

Digital disruption: more pros than cons

Do you get the feeling we've got a government that's worrying about everything except getting on with governing? One issue that's not getting the attention it deserves is the rise of "digital disruption".

The pace at which the continuing revolution in information and communications technology is reshaping industries and occupations is remarkable.

As the consultants Deloitte Access Economics wrote in a report for Google, just a few years ago most consumers logged on to the internet to access email, search the web and do some online shopping. Most of us still accessed the internet using a computer.

"Today, digital technology including cloud platforms, smart hand-held devices and social networks are the new beachheads of the sweeping impacts of the internet," the report says.

"Rapidly evolving from basic connectivity, these technologies are further changing not only how consumers interact with businesses, but also how businesses are organising themselves."

We've seen the digital revolution change the way we buy and listen to music, read books, learn the news, shop, do our banking, pay bills and check in on flights. Its changes to the news media and banking and other financial services have a long way to run yet.

The digital revolution is about information in all its forms, how it's gathered, processed, accessed, transferred and stored. "Big data" is about how all this information is analysed to produce further information about how we behave.

This is why you don't have to be very brave to predict that digital-driven change will be affecting many more industries before it's through.

As the consultants say, while reaching new customers and responding to customer needs is a big reason for businesses to go online and to use social media, we're now seeing "transformational change" inside businesses as they take advantage of the efficiencies that advances in digital technology are making possible.

This means "cloud, data analytics and machine-to-machine technologies" emerging as a second big driver of change. (It also means you and me learning to live with a lot of high-sounding words we barely understand.)

And phones are taking over the world. "The rise in mobile access to the internet and digital services through smartphones and connected devices [I think that means iPads] has prompted new ways of thinking about presenting information to consumers on smaller screens and capitalising on usage trends."

Read your newspaper on a phone? Sure. Many people already do, and we're working to improve our offering as we speak.

Hip business people speak of digital disruption as though it's a wonderful thing. It will make the world a better, faster, easier place, so bring it on.

But that word "disruption" sounds more nasty than nice. So which is it to be?

Both. If new inventions take hold and spread it's because enough people really do think they're an improvement.

But that doesn't stop the industries and businesses most affected by the advance from being turned on their head and maybe even forced to close. So the benefits to customers usually come at a cost to many workers.

Some are redeployed, some become redundant. Most ejected workers eventually find a new job – even if it isn't always as good as the one they left – though some, particularly older people, may never get back on their feet.

But how far have we got with the digital revolution to date? Deloitte Access Economics has gathered what we know and done some rough figuring in a report for the Australian Computer Society.

The consultants say that, compared with other developed countries, Australia is a high-level user and adopter of information and communications technology, with comparatively high rates of mobile broadband penetration and business adoption of digital technology for commercial practices.

According to the Organisation for Economic Co-operation and Development, for every 100 people in Oz there are about 114 subscriptions to mobile wireless broadband, more than any other country bar Finland.

Almost three-quarters of our businesses have a website and a very high 38 per cent of businesses actually make sales over the internet.

The OECD says our information technology specialists make up 3.6 per cent of our workforce, which puts us right behind the Nordic countries and North America. Using a broader definition, about 22 per cent of the workforce is in info-technology-intensive occupations.

The consultants' own estimates say about 300,000 info-tech workers are in the industry proper, with about another 300,000 in other professional and scientific service industries, public administration, financial services and various other industries. This amounts to 5 per cent of the workforce.

They estimate that the digital economy contributed almost $80 billion to gross domestic product in 2013-14, well up on their previous estimate in 2011 and about 5 per cent of the total economy.

But they identify two areas of weakness. First, the 10 per cent of our total annual spending on research and development that we devote to information and communications technology is way behind other developed economies, even small ones.

Second, demand for info-tech workers is expected to grow by 100,000 over the next six years, but Australian new graduates with info-tech qualifications have declined significantly since the early noughties.

More than 10,000 temporary skilled migrant 457 visas have been granted annually to info-tech workers in recent years. In 2013-14 it was closer to 20,000.

Really? This is the best we can do by our own young people? Surely we should be trying harder.

Mainstream economics remains highly useful

When Gigi Foster gave a radical speech to the Economic Society in Sydney last week – which soon had the audience interjecting and arguing among itself – she was careful to begin by saying her goal was to add to the standard economic model, not replace it.

She claimed the economists' model was the most successful model in all of social science, then listed what she considered to be its four most useful contributions.

By rights I should be telling you about her radical additions to the model, but I'll save that for another day because I, too, have been known to be fairly full and frank about the model's weaknesses and, like her, I don't want anyone thinking that means I regard it as a load of bulldust.

Just the reverse, in fact. It's been so useful and so influential that most of its insights will strike you as bleeding obvious. They are now.

Dr Foster, an associate professor at the University of NSW, is one of Australia's leading behavioural economists. Along with Professor Paul Frijters​, of the University of Queensland, she's the author of the ground-breaking book, An Economic Theory of Greed, Love, Groups and Networks.

Her first "big hit" of conventional economics is its discovery that there are "gains from trade". And what's true within an economy – where we each specialise in producing something we're good at, then use money to trade with others – is equally true between economies.

It follows that countries preferring self-sufficiency to the interdependency of international trade will forgo much prosperity. One of economics' earliest discoveries is the benefit of "comparative advantage": countries do best when they concentrate on producing those things they can make at least opportunity cost relative to other countries' opportunity costs.

So you avoid erecting barriers to trade, follow your comparative advantage and import the rest from the cheapest suppliers.

Foster's second big win for economics is realisation of the benefits of competition – not just between producers but also between producers and their customers. So we prevent or regulate monopolies. We create markets when none exist – by, for instance, putting a price on carbon.

And we intervene in markets where we see that competition isn't sufficient to prevent them from failing to deliver the benefits we expect and where the intervention is likely to make the market work better.

Third, a natural role for governments is the provision of "public goods" – goods or services whose nature prevents private producers from capturing enough of the benefits to induce them to provide as much of the item as is in the community's interests.

Examples of public goods provided by governments are numerous: infrastructure, defence, education, the system of law and even the currency.

Foster's final example is the finding that monetary incentives matter. People respond to price changes – though their degree of responsiveness or "elasticity" varies under the influence of other factors. Taxation discourages economic activity, leading to a "deadweight loss" to the community.

That's Foster's list of insights we owe to economists and their model, but I can think of a few more. One is the aforementioned concept of opportunity cost. Because economic resources – including environmental assets – are limited, anything we choose to do comes at the cost of everything else we can't do with those resources.

Since these other things are endless, economists measure opportunity cost by looking only at the next most desirable thing we could have done. The moral of opportunity cost is: since you can't have everything, choose carefully.

Another insight is that anything we choose to do will bring costs as well as benefits. Moral: be sure to weigh the costs against the benefits before you jump.

Then there's our tendency to look only at the initial effect of particular developments. Economists know to ask the next question: but then what happens? It's usually the reaction to the initial effect – the "second-round effect" – that matters.

Say there's a big rise in the cost of electricity. The initial effect is to leave you with less money to spend on other things, which you hate. So you react to this by using power less wastefully, by buying a more energy-efficient fridge next time, or by investigating the costs and benefits of installing solar panels.

All this may seem obvious, but that's a measure of the economists' success in influencing the way we think.

Even so, it's surprising how often we forget these things. That's why we need economists as well as their model: to keep reminding us of the seemingly obvious and doing what they can to stop us wasting money.

Uni economics declines at hands of accountants

If you think economists have too much influence in the halls of power - or that Australia would be better off if its accountants and business people knew less about how the economy works - or that the political debate would be improved if fewer citizens were economically literate - I have good news: academically, the economists are being cut down to size.

And it's the accountants who are doing it.

While business and management courses and departments are booming, many universities are cutting back, even abandoning their teaching of economics. Faculties of economics are becoming business schools.

At the University of Sydney, the economists have been ejected from their own faculty and - along with the political economists - consigned to the outer darkness of the arts faculty (where, as it happens, they're getting more customers).

It may not be long before, to be able to study economics at uni, you'll need an ATAR (Australian tertiary admission rank) high enough to get into one of the "sandstone" universities, the Group of Eight (Go8): Australian National University, the universities of Sydney, Melbourne, Adelaide, Queensland and Western Australia, plus Monash and UNSW.

Trouble is, the sandstone unis don't rate as well on teaching as do the newer, smaller metropolitan and regional unis. Their top priority is research - and don't believe anyone who tells you researchers make the best teachers.

The story of the decline of academic economics in Australia has been told in several papers by Dr John Lodewijks, of the University of NSW, and Dr Tony Stokes and Dr Sarah Wright, of the Australian Catholic University.

At La Trobe University in Melbourne, the school of economics has had to greatly reduce its staff, with fewer professors. Its stand-alone economics degree is no longer offered. Similar changes began at the University of Western Sydney in 2012.

Victoria University's department of applied economics has been broken up, with staff now teaching finance and international business. Economics is being subsumed within business at the University of Newcastle, University of New England, University of Tasmania and James Cook University in far north Queensland.

Griffith uni on the Gold Coast has reduced its offering in economics. Edith Cowan uni in Perth has discontinued the economics major within its bachelor of business. Its economics teaching staff has been slashed, with most of those remaining now teaching finance and quantitative methods. Curtin uni in Perth has also got rid of many economists. Even at the uni of WA a bachelor of economics is no longer offered.

As with Sydney uni, at the multi-campus Australian Catholic University economics has  been ejected from the business faculty and transferred to arts.

When I did a commerce degree at the uni of Newcastle in the late 1960s, three years of economics were compulsory. These days in business courses it's down to one year - or less.

It's clear the accountants would like to be rid of economics completely. What holds them back is that their degree would lose accreditation with the professional accounting bodies.

Over the period from 2002 to 2011, Australia's total student load grew by 40 per cent. The economics students' load rose by just 28 per cent.

From 2012, but with transitional arrangements starting in 2010, universities' enrolments of domestic students were deregulated, meaning unis could enrol as many students as they liked and also that the federal government could no longer influence the number of students studying particular subjects. Enrolments became "demand determined".

The objective of this was to ensure a higher proportion of school-leavers went on to uni. So it has involved a general lowering of ATAR cut-offs for entry into particular courses.

Despite the growth in student numbers overall as a result of the uncapping of places, the number of students studying economics actually declined between 2008 and 2013.

The overall increase in domestic undergraduate commencements was 34 per cent. Business and management numbers rose 38 per cent, and marketing and sales courses rose 39 per cent. But economics commencements fell by 7 per cent to fewer than 5400.

Between 2007 and 2014, the average ATAR cut-off for "business/commerce" (which would include economics) at non-Go8 unis fell by 7.8 points to 65.1, while the average for the Go8 rose fractionally to 89.1.

It seems that the sandstone unis are now capturing more of the able students who formerly would have gone to the newer, lesser-status metropolitan and regional universities.

And it seems all this has allowed a turning away from economics. It's likely  the subject is perceived by students as more intellectually demanding, with less well-prepared students preferring business studies. Many people think business studies is more practical and more likely to lead to a job.

University managers want to shift resources to the subjects in greatest demand from students and probably think they're more likely to get funding from businesses.

So the teaching of economics is contracting and concentrating in the group-of-eight unis. But while these are well known for their high quality research, they're not particularly noted for high quality teaching of economics.

Research has shown a negative relationship between research quality and student satisfaction with teaching. And studies of course-experience questionnaires show that the elite unis perform worse in student satisfaction with teaching than the other unis, particularly the newest ones.

It was two of the lowest ATAR unis, Australian Catholic and Western Sydney, which achieved the highest scores - 86 and 80 respectively - in the good-teaching category.

It's easy to blame an intellectually lazy younger generation. But, to some extent, the academics have brought this on themselves.

There are plenty of hard subjects at uni, but for decades economists have taught economics as though it's only the cultivation of future PhDs that matters to them, making little attempt to capture young imaginations by demonstrating the practical relevance of their dry, ever-more mathematical theories.

Trouble is, it's not only they who'll pay the price of their neglect.

BANKING AND FINANCE IN AN UNCERTAIN FUTURE

Talk to dinner guests of Hall & Wilcox, lawyers, in association with the Wheeler Centre, Melbourne - Wednesday, July 29, 2015 in Sydney & Tuesday, August 4, 2015 in Melbourne

I’ve been invited to talk to you about the future of banking and finance which, being a journalist, I’m more than happy to do. As a great newspaper owner from the Victorian era, Lord Northcliffe, once said, journalism is a profession whose business is to explain to others what it personally doesn’t understand. I know a fair bit about the economy, a fair bit about budgets and monetary policy and a fair bit about the news media, but I’m no expert on banking and finance, and I’m certainly no techhead.

In preparing for tonight I faced two choices: I could give you a gee-whiz job about all the radical, amazing, frighten changes that are about to engulf us, or I could give you the benefit of the views of grumpy, somewhat cynical old man who’s been watching banking and finance from the sidelines for 40 years and, in particular, watching the process of economic and social change over that time. You can’t be a commentator without being a student of change. I’ve decided to give you a bit of both, but less of the gee-whiz and more of the sceptical old fart.

But before I get into it, let me say this: it never ceases to amaze me that people never tire of asking economists - or, in my case, economic journalists - to tell them what will happen in the future. They keep doing this even though they know full well that economists are hopeless at forecasting. Why? Because as humans we’re addicted to the desire to know what the future holds so we can do something about it: stop it, sidestep it or exploit it. Psychologists call this humans’ “illusion of control”. We have an ingrained belief that if we can find out what’s coming up we can control what happens to us. It’s an illusion, of course. No one knows what the future holds and our ability to change it is usually a lot more limited than we imagine.

It’s because our desire to know and influence the future is a product of our evolution as a species that no amount of bum forecasts in the past deters us from asking for another forecast. So let me oblige. But rather than getting down to a few sexy, gee-whiz examples, I’m going to give you a more top-down, analytical view.

Around the world, and in Australia, banking and financial markets have been changing continuously since the early 1980s - that is, for about 40 years, because of the interrelated forces of globalisation (including the increased integration of the world’s financial markets), changing attitudes to regulation (first deregulation and now a degree of reregulation), and technological advance (particularly greatly reduced costs of telecommunication and of the collection, analysis, transfer and storage of information).

The practice of banking involves “intermediation” - taking deposits from savers and lending the money to investors - and “maturity transformation”: borrowing money for short periods or at call, but lending money for long periods of up to 25 years. Australia’s banking system, like most countries’, has long been dominated by a small number of very large banks, engaged in providing the full range of financial services: facilitating payments, taking deposits and making loans, providing investment advice and the management of assets, and actively participating in most financial markets, for short-term money, securities, foreign exchange, shares, derivatives and so forth. Why is banking so oligopolistic? Because of high barriers to entry arising from economies of scale and the high cost of information.

At this point the main sources of change in banking and finance are, first, continuing changes in the regulation of banks and other major financial players as governments and financial regulators seek to prevent another global financial crisis and, second, continuing innovation as entrepreneurs seek to exploit the opportunities and greatly reduced information costs created by the digital revolution.

The main question we’re considering - the main imponderable - is the extent to which changes in regulatory requirements and in information costs will reduce the barriers to entry, break down the banks’ dominance in the provision of financial services and lead to a flowering alternative suppliers of those services.

The international regulators’ efforts to raise the capital and liquidity requirements imposed on the world’s banks will reduce their gearing and thus, as they frequently complain, increase their costs of intermediation. Whether these greater costs will be borne by the banks’ shareholders or passed on to their customers will be determined by the strength of competition in the relevant markets. But, either way, the higher cost of intermediation will make the banks vulnerable to unregulated suppliers of financial services. As witnessed by the growth of Australia’s corporate bond market, our big corporates are already borrowing directly from the market rather than from banks, and this practice is likely to move down to medium-sized corporates.

Of course, to the extent that the costs of tighter capital requirements shift transactions from the regulated to the unregulated sector, it will frustrate the regulators’ efforts to reduce the risk of another financial crisis. But don’t underestimate the regulators’ ability to fight back by using the digital revolution’s huge reduction in the cost of gathering and analysing financial information to impose much greater disclosure of transactions of non-banks as well as banks (see the speech by Andrew Haldane and others at the Bank of England, in March 2012).

At last we’re up to the sexy bit: all the amazing new products, and opportunities and new players that are likely to emerge as digital disruption reaches banking and financial services. As a journo I do know something about the way the digital revolution is hugely disrupting one industry after another, changing their face for ever. Whatever scepticism you may hear from me, be clear on this: I don’t for a moment doubt that major digital innovation is coming to banking and financial services.

For a full list of every presently conceivable innovation that may possibly disrupt banking as we know it, I refer you to the report on The Future of Financial Services, prepared by Deloitte and others for the World Economic Forum in June this year. But picking out the highlights, in payments system category we have mobile money and digital wallets, such as Apple Pay and Google wallet. This will continue the reduction in the use of cheques and cash, increasing the efficiency of the payments system to the benefit of all, but without much disruption to the banks. We can perhaps reduce the involvement of banks in the making of payments, but I don’t see how we can get away from holding our money in banks. If so, there’ll be a bank somewhere at either end of the payment, even if the transfer isn’t actually conducted by a bank.

Of course, we could keep our money in “crypto currencies” such as bitcoin, but so far the only people doing so seem to be crooks and a few geeks who love trying anything new. If you go back far enough you find we have a history of non-government money - of banks issuing their own banknotes - and it wasn’t a happy one, hence the ultimate outlawing of private money. Apart from any risk benefits from a government monopoly over the issue of fiat money, remember that governments and their central banks benefit greatly from seigniorage.

Turning from payments to intermediation, we come to peer-to-peer lending. The main point here, I think, is that you don’t need to be a bank to match a person or company wanting to lend a certain sum for six months or five years with a person or company wanting to borrow that sum for the same period. Nor do you have to be a bank to assess borrowers’ credit worthiness using advanced software. But matching is not intermediation; it’s not standing between the depositor and the borrower so that the depositor’s claim is against a big, regulated, virtually government-guaranteed bank, not against some puny borrower. Similarly, matching is not maturity transformation; it’s not using a thousand at-call deposits to issue one 20-year loan. Both intermediation and maturity transformation involve taking risks. If a digital upstart doesn’t take on those risks there wouldn’t be many people wanting to lend through them rather than a bank. Certainly, not after the first time the economy had turned down and caused many borrowers to be unable to repay their debts. Were the digital upstart to take on those risks it would either have to lay them off to a bank, or with help from a bank, or it would itself become a virtual bank - in which case it wouldn’t be long before the bank regulators began regulating it.

Turning from intermediation to investment management, much of which is done today by bank subsidiaries, it’s not hard to see that digital upstarts could have success in offering automated, and hence cheaper, advisory functions and actual asset management. But one question is how many punters - or even businesses - would be happy to hand their savings over to a financial robot rather than a human with a good bedside manner.

Summing up, it’s clear that digitisation gives new entrants to the financial services industry the potential to greatly reduce the costs of gathering, processing and transferring financial information. They also have the potential to create valuable new information from the analysis of that financial information. And they have the advantage of having no legacy assets or attitudes.

By the same token, incumbency also carries some advantages. The banks have deep pockets to match the upstarts on the digitisation of financial information or to buy out or copy innovators that succeed with new tricks. And they have a record of being early adopters of improved technology.

But banking is very different from news or books or records or shopping for sneakers. Banking is much more about managing of various forms of risk. And to me the key question is whether digital innovation offers any great advance in the management of risk in addition to its advantages in the management of information. If it doesn’t, I doubt if it will get far. If it does, the banks really will be given a run for their money. But remember that the regulators’ primary concern is systemic risk - the ability of failures in the banking system to inflict great damage on the rest of the economy. So if the digital upstarts do become bank-like - the banks you have when you’re not having banks - I don’t imagine the authorities would waste too much time in starting to regulate them as banks. Bill Gate’s famous saying that “we need banking but we don’t need banks” is a non-sequitur. Any rival outfit that steals the banks’ core business itself becomes a bank.

Now, at last, we come to the part where the grumpy old man comes out of his cave. People have been predicting the demise of the big banks since the advent of financial deregulation in the 1980s - so far to no avail. Can you remember when the entry of the foreign banks was going to do in our local banks? Can you remember when deregulation and the emergence of superior specialised rivals in the provision of particular financial services was going to dismember our big universal-provider banks? So far, whatever the challenge, our big four have gone from strength to strength. Moral: don’t write them off too cheaply.

Next, if you want advice on what the future holds for banking and finance, my advice is that you’ll do better talking to economic historians and the students of earlier waves of major technological innovation - from the railways to electricity to the internal combustion engine to radio - than listening to futurologists and tech-heads. One thing the students of economic history will tell you is that it can take decades for the full commercial potential of major advances to be uncovered and implemented. Another is that the hundred or more start-ups determined to make a killing out of producing automobiles (or whatever) will eventually pack down to just a handful of big, successful, long-lasting corporations - GM, Ford and Chrysler - but until the end it’s impossible to predict who the victors will be.

Even in terms of which gee-whiz new ideas will survive and prosper, and which won’t, the futurologists have a list of failed predictions as long as your arm. They impress us because they seem to know so much about the new technological wonders just over the horizon, but this is their downfall: they love the technological and they love novelty. What they don’t know much about is human nature. Consequently they fail to make the key distinction between what new technology could do for us and what we’ll want it to do for us. Only the stuff we want - the stuff that fits in with human nature - will survive and prosper. Consider the lack of interest in telecommuting. Or the continuing concentration of the financial markets despite the move to electronic trading. Predictors must never forget that humans are intensely social animals. We like to be with others. Urban economists studying the increasing concentration of GDP - value-adding - in CBDs are realising that we learn from being in contact with others. It seems conference calls, even Skype, are a poor substitute for face-to-face contact. MOOC - massive open online courses.

Next, what drives technological change is competition and the desire for profits; business outsiders trying to steal a march on the incumbents, or insiders on their fellow incumbents. I remember Bob Gottliebsen before the Tech Wreck banging on about the huge profits to be made from B2B. But if you study the major technological advances of the past you soon realise that what starts as business people out to make a killing ends up delivering its greatest benefit to customers. The way it works is that any player who comes up with a really successful innovation will soon be copied - by other outsiders and, eventually, by the incumbents- which forces down prices and profits, and shifts the benefit to customers. Apart from any history, I know this from the digital disruption of classified advertising in newspapers. The users of classified ads for houses, jobs and cars have ended up with an infinitely better product for a fraction of the price of an old newspaper classified.

This process by which well-functioning market economies deliver the benefits of digital disruption and other technological change to customers rather than capitalists is one of the great attractions of capitalism. Which is why, though I’m uncertain how much digital disruption will do knock the banks off their perch, I am confident the new or improved products we end up with will be of great benefit to the users of financial services.

Job insecurity isn't as great as you imagine

As everyone knows, the world of work just gets tougher. For a start there's the ever-growing incidence of "precarious employment" – people in casual jobs, or on short-term contracts, or working for labour-hire companies or temping agencies, or being cast adrift by their employer without benefits as supposedly self-employed.

If you do have one of the ever-scarcer full-time, permanent jobs, you're probably working a lot longer hours than you used to. Unpaid, I'll be bound.

These days, no one stays in the same job – even the same occupation – for very long. More and more people are being made redundant. A young person leaving education can expect to have many different jobs before finally they retire at 70.

It won't be long before many people don't so much have a job as a portfolio of jobs – different things they do for different outfits in any week or month, hoping that when they add it all together it amounts to a reasonable living.

All pretty terrible, eh? There's just one problem – it might be what everyone knows, but none of it's true.

Two profs at the University of Melbourne's Melbourne Institute, Roger Wilkins and Mark Wooden, have looked at the figures and they question all we think we know. Their findings were published in the Australian Economic Review.

It is true we have a lot of part-time and casual employment in Australia – more than in most other rich countries – much of it done by mothers with young families and students who aren't wanting a full-time job. And, these days, by people in semi-retirement.

It's also true that the number of part-time and casual jobs grew rapidly for several decades. It's still growing, but much more slowly.

According to the authors' reading of the figures, over the 10 years to 2013 the proportion of men working part-time has increased by 2 percentage points to just under 18 per cent, while the portion of women has been steady at almost 48 per cent.

While most part-timers are also casuals, the two groups don't overlap completely. The Bureau of Statistics defines casual employment as not receiving paid annual leave and sick leave. Its figures show that, for men, the proportion of casuals has been relatively steady since the late 1990s, fluctuating about 20 per cent. Among women the share has fallen from about 31 per cent to less than 27 per cent.

The annual household, income and labour dynamics in Australia – HILDA – survey shows that more than two-thirds of workers were in permanent or ongoing employment in 2012, an increase of 1.5 percentage points since 2001, when the survey began.

HILDA suggests the share of labour-hire and temporary-employment agency jobs has fallen over that time from 3.7 per cent to 2.7 per cent. (It would be much higher than that in particular industries, of course.)

Nor can Wilkins and Wooden find any evidence that there's been a shift away from employment to greater use of self-employment. Indeed, the stats bureau's figures show the proportion of self-employed in the workforce has been steadily declining over the past 20 years, from 14 per cent to 10 per cent in 2013.

Turning to overwork, there was a time when it was increasing (which got a lot of media publicity), but since then it's been declining (which has got little).

Among men working full-time, the proportion working no more than 40 hours a week increased from 52 per cent to 58 per cent over the 10 years to 2013. The proportion working more than 50 hours fell from 31 per cent to 27 per cent.

That's still a lot, of course. But remember that the people you'd most expect to be working long hours are managers and highly skilled professionals, and these have long been the two fastest-growing occupations. Such people rarely get paid overtime. Rather, the long hours they work are reflected in their hefty annual salaries.

Then there's the widespread perception that these days people are always losing their jobs and having to move on. When employers announce mass layoffs it invariably gets much attention from the media. When there's nothing to announce it gets no attention.

The stats bureau's figures for average job duration and rates of job mobility show little sign that jobs have become less stable, the authors say. In February 2013, just 18 per cent of the employed had been in their job for less than a year, down from 22 per cent in 1994.

In the latest figures, just over one worker in four had been in their job for at least 10 years, up from 23.6 per cent in 1994.

Of course, how long people stay in the same jobs is determined by both dismissals and quits. If jobs are becoming less secure you'd expect dismissals to be up and voluntary departures down.

Both of these vary with the ups and downs of the business cycle but, even so, they've tended to decline. In February 2013, fewer than 3 per cent of all the people who'd had a job in the previous 12 months had been retrenched.

The proportion losing their jobs for any reason was 6 per cent. About 10 per cent of people had quit their jobs.

There are a lot of problems in the world, including the world of work, but let's not imagine more than actually exist.

Why the economy's slow growth may last

The biggest economic story last week wasn't all the wishful thinking about raising the goods and services tax, it was Reserve Bank governor Glenn Stevens' warning that the economy's "potential" rate of growth may be lower than we've assumed.

Predictably, those commentators who did see the significance of this news were too busy putting their own spin on it to make sure what Stevens' said was widely taken in. So let me have a go.

The macro managers' long-standing belief that the economy's "trend" rate of growth is 3 per cent a year or a fraction more has been challenged by the Bureau of Statistics' labour force estimates showing that, over the past year, the rate of unemployment has stabilised at 6 per cent.

Trouble is, the latest national accounts show the economy growing by only 2.3 per cent over the year to March. This is well below the trend rate that, almost by definition, is the rate at which the economy must grow to hold the unemployment rate steady.

How is this discrepancy explained? Stevens ran through the range of possibilities. Maybe employment hasn't been growing as strongly as the figures say at present. Maybe the economy has been growing more strongly than the figures say at present.

Or maybe part of the surprisingly strong growth in employment is explained by the unusually slow growth in wage rates, which would be saving some jobs and creating others.

The final possibility – and the one to which Stevens gives most weight – is that the trend rate of growth is lower than we've assumed, thus allowing unemployment to stabilise at a lower rate of economic growth than we've assumed.

Economists use the term "trend" in both a backward-looking and a forward-looking sense. If you calculate our average actual rate of growth over the past 10 or 20 years, this must have been our "potential" growth during that period.

If nothing in the economy has changed over that time, it should also be our average, trend rate of growth in the coming five or 10 years.

However, things do change – the population ages, for instance – so economists have to make guesses about what our potential growth rate will be in the future.

Our potential growth rate is the maximum rate at which the economy can grow on average over the medium term without a causing a serious inflation problem. It's set by the economy's supply side.

It represents the average rate at which the economy's capacity to produce goods and services is growing. And this is usually thought of as being determined by the rate of growth in the working population plus the rate of improvement in the productivity of labour.

(Whether in any particular year the economy is growing at a rate below, at or above its potential growth rate is determined by the strength of demand at the time. However, the economy can grow faster than its potential "speed limit" only for as long as it has idle production capacity to use up.)

But this is where those commentators who cottoned on to the significance of Stevens' views jumped to their own conclusions about what was causing the suspected slowdown in potential growth. They assumed it must be caused by a slowdown in labour productivity improvement.

Why? Because this fits well with the economists' (including Stevens') long-running campaign to persuade us to undertake more micro-economic​ reform so as to raise productivity and, hence, material living standards.

What they missed in their missionary zeal was Stevens' clear indication that he thought the culprit was slower-than-expected population growth.

The econocrats' figuring suggest a potential growth rate of 3 per cent would be explained by population growth of 1.7 per cent to 1.8 per cent a year, plus growth in labour productivity of 1.2 per cent to 1.3 per cent a year.

So their expected rate of productivity improvement is already pretty low, while the end of the mining construction boom and slow growth generally have seen population growth slow to 1.5 per cent a year or less as the net intake of workers on temporary 457 visas falls and Kiwis go home to a faster-growing economy.

The other thing the missionaries missed was Stevens point that, to the extent the lower trend rate is caused by lower population growth, it shouldn't involve any slower rate of improvement in our material living standards, as measured by growth per person.

Missionary micro-economic reformers won't win lasting converts by misrepresenting our present position, nor the outlook for growth. Their pessimism about future productivity improvement isn't supported by our more recent performance. It's little more than a guess.

We're not doing too badly on productivity

Rummaging through the media's rubbish bins this week, I happened upon some good news. According to the Productivity Commission's annual update, the productivity of labour improved by 1.4 per cent in 2013-14.

And get this: in the 12-industry "market sector" of the economy, it improved by 2.5 per cent in that year and by 3.7 per cent the year before.

To give you an idea, the 40-year average rate of market-sector productivity improvement is 2.3 per cent. So, despite all the worrying we've been doing in recent years about our poor productivity performance, it seems we're now doing quite well.

In which case, how come no one wanted to tell us? I can think of three reasons. First is the media's assumption that good news is of little interest to their customers.

Second is that the Productivity Commission's preference is for brushing aside the labour productivity figures and getting us to focus on the figures for "multi-factor productivity", which show an improvement of just 0.4 per cent in 2013-14 and 0.4 per cent the year before. This compares with the 40-year average of 0.8 per cent a year.

Third is that the nation's economists are engaged in a campaign to persuade us we need a lot more micro-economic reform so as to raise our rate of productivity improvement and, hence, the rate at which our material standard of living is rising.

They'd make the same argument whether our productivity performance was good, bad or indifferent, but it helps the selling job if they leave us with the impression our recent performance is poor.

Anyway, let's take a closer look at the commission's new figures. Productivity, which compares the growth in the output of goods and services with the growth in inputs of labour and capital, is a measure of the efficiency of our production. When outputs grow faster than inputs, the economy – the economic machine, so to speak – has become more efficient.

The simplest (and probably least inaccurate) way of measuring productivity is to take the increase in the quantity of goods and services produced during the year and divide it by the increase in the total number of hours worked to produce the stuff.

The main way to increase the productivity of workers is to give them more machines to work with. But the commission believes a more revealing measure is multi-factor productivity. You calculate this by dividing the increase in output by the increase in labour inputs plus the increase in capital inputs (use of machines and other equipment).

The main thing causing an increase in multi-factor productivity is technological advance – the invention of better machines plus improved ways of running businesses. But also improvements in "human capital" – the rising education and skill of the workforce.

That's all fine in theory, but it gets pretty ropey in practice. For a start, we have no way of measuring the productivity of the public sector (healthcare, education and public administration) because, for the most part, it doesn't sell its output in the market.

The market sector covers the financial services, mining, construction, manufacturing, transport, retail trade, wholesale trade, information media and telecommunications, electricity gas and water, agriculture, accommodation and food services, arts and recreation services, rental hiring and real estate services, professional scientific services, administrative support services, and "other" services industries.

That's 16 industries – though, for reasons it doesn't explain, the commission's 12-industry measure of market sector productivity doesn't include the last four industries on that list. Even so, the 12 industries account for 65 per cent of gross domestic product.

A much more serious problem is that the measurement of multi-factor productivity is quite dodgy. It's measured as a residual, meaning that any error in measuring the three other items in the sum will (and does) make the measurement of multi-factor productivity wrong.

More particularly, economists have no way of accurately measuring capital inputs. Just one of their problems is that they can't distinguish between more machines and better machines, meaning their so-called measure of multi-factor productivity excludes much of the technological advance it purports to measure.

The besetting sin of economists is the way they confidently quote their figures to a trusting public, without breathing a word about the data deficiencies and dubious assumptions that lie behind their calculations. When they fail to issue a product warning, it's the duty of the conscientious economic journalist to call them out.

In such circumstances, the commission's results need to be treated with scepticism – particular when, as was true in the noughties, they were so unprecedentedly low as to be implausible.

But let's look at the commission's breakdown of the latest year's supposedly weak result of 0.4 per cent. Half of the 12 industries – all of them in the services sector – achieved remarkably strong improvements, ranging between 1.1 per cent and 5.4 per cent.

Three industries – mining, construction, agriculture – had growing production but marginally declining multi-factor productivity. We know the problems in mining and construction are temporary. Agriculture's poor performance came mainly from drought.

The last three industries – utilities, manufacturing and transport – suffered declining production but lesser declines in inputs, meaning their multi-factor productivity deteriorated quite significantly.

We know the utilities, particularly electricity and gas, are coping with major structural changes, not helped by the earlier misregulation of poles and wires. We know manufacturing is still recovering from the high exchange rate caused by the resources boom. Whatever transport's problem is – we're not told – it will get over it.

That's the trouble with the supposedly worrying figures for multi-factor productivity. Apart from the ropiness of their calculation, when you investigate the stories for the particular industries involved you can't find anything major to worry about.

I'd say that, despite all the barrow-pushers wanting to use poor productivity figures to bolster whatever cause they're promoting, we're not doing too badly on productivity.

Everyone wants a slice of a higher GST

Norman Lindsay called it the Magic Pudding. Economists call it opportunity cost. In the untiring campaign by some for an increase in the goods and services tax, a new magic pudding has been created. The trouble is, opportunity cost is real, but magic puddings aren't.

Put at its simplest, the concept of opportunity cost says that if you've got a dollar, you can only spend it once. This truth might be glaringly apparent, but it's surprising how often grown men (and, less commonly, grown women) forget it.

By contrast, the original magic pudding allowed its owners to "cut and come again". No matter how many times they cut themselves a slice, the pudding would magically grow back.

Just the most recent proposal for a higher GST – of 15 per cent – comes from the Premier of NSW, Mike Baird. He wants it to help the state governments raise more taxation to help them pay for the ever-growing cost of their public hospitals and still balance their budgets.

But Baird and some of his fellow premiers aren't the only people with designs on the extra revenue a higher GST would bring. He's been spurred by the knowledge that, so far, Prime Minister Tony Abbott is sticking with the plan announced in last year's budget to move to a less generous way of indexing federal grants to the states for their public hospitals and schools from 2017, which would cause those grants to grow by $80 billion less than they would have, over the following decade.

There are people cynical enough to believe this cut was aimed at softening the premiers up and obliging them to agree to an increase in the GST as the only solution to their future funding problems.

But do you see what this means? It means a big slug of the extra revenue raised by a higher GST would go towards solving the feds' budget problems, not the states'. Suddenly, the pot of gold isn't looking so big.

But that's not all. There are a lot of economists and business people urging that the proceeds from the higher GST first be used to abolish various state taxes regarded as "inefficient" – that is, ones that have the effect of seriously distorting the choices people make.

Top of the list of inefficient state taxes is stamp duty on the transfer of commercial and domestic properties, and the tax on insurance policies. But some business people have their eye on using the GST to replace payroll tax. And a lot of landlords would like to get rid of land tax.

But why stop at eliminating state taxes? Why not use it to reduce a few federal taxes you don't like?

Big business is very anxious to "reform" the tax system by using a higher GST to cut the rate of company tax. And many high income-earners believe it vitally important to cut the top personal tax rate, lest all our top people migrate to countries where taxes are lower (Malaysia, say).

It's clear Treasurer Joe Hockey would very much like to cut company tax and the top tax rate for individuals, if only the boss could summon the courage (and Hockey's powers as a salesman were magically transformed).

But Hockey has another problem he'd no doubt like the GST's help with. He knows that the main thing he's using to allow him to project slowly declining budget deficits in coming years is ever-rising collections of income tax, caused mainly by "bracket creep" – inflation pushing people into higher tax brackets.

The trouble is, after a while, people notice the higher tax rate they're paying on any overtime or pay rise. When they do, they tend to get pretty stirred up and look for a politician to blame.

So Hockey knows that, before long, he'll need to have a tax cut that gets people on tax rates below the top one back into lower brackets. It would be nice if he could make up some of this lost revenue by increasing the GST.

See the magic pudding? There's a host of different groups pushing for higher GST, but they all want to use the proceeds to pay for something different. Between them they have plans to spend each extra GST dollar many times over.

That's true even if, as well as simply increasing the rate to, say, 15 per cent, we also extended it to cover food, education, health and financial services.

And don't forget this: because the GST is universally acknowledged to be a "regressive" tax – it takes a higher proportion of low incomes than of high incomes – it would have to come with a lot of "compensation" for low- to middle-income earners, in the form of increases in pensions and the family allowance and cuts in income tax at the bottom.

All this compensation would have a cost. In other words, the net proceeds from raising the GST would be a lot lower than the gross.

If you get the feeling the debate about increasing the GST has entered the realm of fantasy, you're not wrong. Once the more fanciful ways of using the proceeds had been eliminated, the number of people pushing for it would be greatly reduced.

If you get the feeling this means the GST won't be going up any time soon, you're not wrong, either. I won't be losing any sleep over it.

Tax reform push doesn’t add up

For once the Business Council has said something those who don't champion the interests of big business can agree with. We have indeed reached a new low in the nation's political leadership.

The council's president, Catherine Livingstone, said last week that "at a time of great economic uncertainty, Australia needs and deserves strong leadership, and the opportunity to discuss reform options as a community".

"Our political representatives are elected and paid by the community to implement policies that will best serve the country. Their leadership responsibility is to ensure that there is a constructive, well-informed debate, leading to implementable outcomes; it is not to undermine the debate in the cause of party political positioning."

Livingstone's rebuke was rightly aimed at both sides of politics and both levels of government. But it must be said that Tony Abbott is the worst offender. Clearly, a government has greater responsibility to lead than an opposition.

The federal opposition's responsibility is not to descend to the level of destabilisation and automatic obstruction resorted to by the previous occupant of the position. Abbott is forging new lows on both sides of the Speaker's chair.

It was Abbott who, not long after Joe Hockey made his first call for a "sensible, mature debate about tax reform", summarily ruled out reform of negative gearing and superannuation tax concessions.

Why? Because Labor signalled its intention to propose such reforms and Abbott saw a chance to wedge Labor by portraying it as high taxing and the Coalition (with all its bracket creep) as low taxing.

Hence Livingstone's reference to "party political positioning". The sad truth is, these days governments rarely propose any "reform" without using it to attempt to wedge the other side. Kevin Rudd tried it with his failed carbon pollution reduction scheme, and Julia Gillard tried it with the Gonski education reforms and the national disability insurance scheme.

There's nothing Bill Shorten would like more than to wedge the Coalition on changes to the goods and services tax (apart from being given an excuse to proclaim the return of Work Choices), but Abbott lost no time in wriggling out of promising any serious change to the GST by imposing a condition he knew would not be fulfilled: every premier must first agree to the change before he endorsed it.

Those calling for greater bipartisanship on tax reform need to remember that, of all the areas of reform, taxation is the one where it's been least evident in the past. The Coalition (and the Business Council) opposed Paul Keating's introduction of capital gains tax and fringe benefits tax.

Labor opposed John Howard's introduction of the GST; the Coalition opposed Labor's introduction of the carbon tax and the mining tax. The only instance of bipartisanship I remember is Simon Crean (foolishly) waving through Howard's halving of the capital gains tax.

The parties divide on tax because there's no issue where the two sides' continuation of class warfare is more apparent. The Coalition seeks to favour the interests of business and high-income earners; Labor tends to favour middle and lower-income earners.

While in opposition, Abbott promised his big-business backers he'd take proposals for major changes in taxation and industrial relations to the 2016 election. But the public's rejection of his first budget as grossly unfair, and his subsequent poor showing the in polls means the government is fighting for survival, with no stomach for unpopular "reforms" of taxation or anything else.

Last week we had Hockey giving a speech that pretended the tax reform white-paper process was alive and well, even though we all know it's going nowhere.

He repeated his call for a mature debate about tax reform, while ruling out various reforms – changes to super tax concessions, negative gearing, the half tax rates on capital gains, the GST – and listing the changes he favoured (at some wonderful time in the future): a lower company tax rate, cutting the top personal tax rate and doing something about bracket creep.

The government's professed goal is lower taxes and no new taxes but, apart from the rise in GST we're not having, Hockey mentioned no tax he'd be prepared to increase to pay for all those he'd like to cut.

The only way to square that circle is another attempt at sweeping cuts in government spending, or to let budget deficits and debt go up rather than down. But who'd believe that?

The tax changes he fancies are from the Business Council wish-list​, shifting the tax burden from higher earners to lower earners. They'd be just as unfair as last year's budget.

Memo big business: no fairness, no deal. You should have learnt that last year.

All we should be doing to protect land and water

You get the feeling Tony Abbott doesn't lie awake at night worrying about what our economic activity is doing to our natural environment.

In which case, those of us who do care about ecological sustainability – including many Coalition voters and, in all probability, Abbott's successor, whether Liberal or Labor – will have a lot of catching up to do.

This looks like being true of our excessive contribution to global greenhouse gas emissions. But it also applies to the more mundane problems of protecting and restoring our degraded land, water systems and native flora and fauna.

So what should we be doing, even if we aren't yet? The Wentworth Group of Concerned Scientists have produced a paper on Using Markets to Conserve Natural Capital. As the name implies, it has economists' fingerprints all over it.

In many cases the adverse environmental consequences of economic activity aren't reflected in the costs faced by producers and their customers, a classic instance of "market failure" – where the operation of market forces does not produce satisfactory outcomes for the community.

For instance, industries will continue to emit excessive greenhouse gases if there's no market value placed on retaining a stable climate system. And farming may cause land degradation if there's no market value placed on preserving the services the ecosystem provides to society by allowing us to grow food and fibre.

All this is a way of saying that the economy and the environment are inextricably linked but, left to its own devices, the market isn't capable of ensuring we don't stuff the environment and thereby stuff the economy.

Most economists accept this truth, but argue that the least economically costly way to fix the problem is to intervene in markets in ways that harness market forces to the service of the environment.

Often this can be done by getting the social (community-wide) costs of environmental damage incorporated into the private costs borne by producers and consumers. This was the rationale for the Gillard government's policy of using a hybrid carbon tax/emissions trading scheme to put a price on emissions of carbon dioxide and other greenhouse gases.

The concerned scientists accept this logic and propose four market-oriented interventions to reduce future damage to the nation's "environmental assets" and to fix past damage.

Their first proposal is to change the law to impose on all landowners, public or private, a "duty of care" to prevent further damage to their land and water resources. Developing codes of practice would give landowners greater certainty about their obligations.

This reflects the principle that the community's right to a clean and sustainable environment overrides the rights of individuals to unrestricted use of their private property.

Actions of great environmental value that go beyond the standard of care required – such as fixing damage done in the past – could be purchased by governments from private owners using programs that use market-based instruments, such as Victoria's BushTender​ program.

The scientists' second proposal is for the federal government to supplement our efforts to reduce carbon emissions by paying farmers, Indigenous communities and other landowners to engage in "carbon farming" – doing things that improve the rate at which carbon dioxide is removed from the atmosphere and converted to plant material or soil organic matter, where it stays.

If you do this right, it can also be used to restore degraded land. But it involves having a price on carbon so farmers can be rewarded with valuable "carbon offset" certificates.

However, there are risks if the market for carbon offsets isn't properly regulated. "Without complementary land-use controls and water accounting arrangements in place, carbon forests could take over large areas of high quality agricultural land and affect water availability," the paper warns.

"This could create adverse impacts on food and fibre production, and affect regional jobs that are dependent on these industries."

The scientists' third proposal is that we reform the tax system to make it one that doesn't encourage unsustainable practices, but rather encourages the conservation and repair of the natural environment.

"Subsidising or providing economic incentives for fossil fuels makes no sense because it results in increased costs to the environment, costs we will all have to bear sooner or later," the paper says.

It particularly makes no sense when at the same time we're using a tax on carbon to discourage the use of fossil fuels or, as now, spending taxpayers' money to pay for "direct action" to reduce emissions.

And yet our miners and farmers are exempt from paying petrol excise on fuel used off-road. It's the obvious tax break to get rid of – and save the government money.

The paper also recommends establishing a broad-based land tax to provide long-term, equitable funding for paying farmers, Indigenous communities and other land holders to restore and maintain environmental assets in a healthy condition.

Finally, the scientists propose government action to encourage sustainable farming practices. They say farmers need to receive a financial reward for managing their farms sustainably and suppliers, retailers and consumers need to have confidence that their products satisfy rigorous standards.

A farm is sustainable when environmental assets located on the farm are being maintained in a condition that contributes to the overall health and resilience of its surrounding region.

Environmental assets – not all of which will be on farms – include soil, native vegetation, native fauna, water resources (rivers, aquifers, wetlands, estuaries) and carbon.

The financial reward doesn't have to come from the government. Consumers will pay a premium for food that has been grown sustainably, provided they have some assurance this is so.

The government's role is to support the development of voluntary, industry-based sustainable certification of farms and to ensure such schemes are trustworthy. The government should also be active in the development of international sustainability standards so our exporting farmers can participate and benefit.

All very sensible stuff. Now we just need a sensible government.

Increase property tax, not the GST

Let me tell you something neither side of politics will: we'll be paying a lot higher taxes over the next decade than we are today. And don't think you could have up to 10 years before that prediction comes to pass – it's already started.

It's happening because of bracket creep. This year's budget says the present intention is to let inflation push people into higher tax brackets for another five years before our next tax cut in 2020.

The more continuing falls in the prices of iron ore and other mineral exports slow the growth in company tax collections, the further into the future the timing of our next cut in income tax.

So much for the man who says he stands for lower taxes, whereas his opponents stand for higher taxes. It does seem that Labor may summon the courage to go to the next election promising to reduce superannuation tax breaks for the well-off and to do something about negative gearing.

But continuing bracket creep plus those small reforms – should we ever see them – won't be sufficient to stop budget deficits getting ever higher as government spending – federal and state – continues growing strongly. In particular, spending on health and education are almost certain to grow faster than the nation's income (gross domestic product) is growing.

Similarly, don't believe the team captain when he claims to stand for "smaller government". We have the inglorious retreat from last year's budget – which was intended fix the budget deficit for good and all, and do so almost solely by cuts in government spending – to convince us that the electorate simply won't tolerate the scale of cuts, nor the unfairness, needed to hold our spending down to the level that receipts from our present collection of taxes are able to cover.

Usually, this is the point where the question of raising collections from the goods and services tax is raised. Either raising its rate from 10 per cent, or broadening its net to include food, education and health. Or both.

Be under no illusion, the rich and powerful of this country have their hearts set on raising more from GST. They want it not to cover ever-rising government spending but to cover the cost of cutting the rate of company tax and the top rate of income tax.

They argue that globalisation has intensified the "tax competition" between countries. Financial capital is now a lot more mobile and if we tax it too heavily it will go elsewhere. So we need to cut our taxes on highly mobile resources (company tax and income tax on highly paid executives) and increase tax on less mobile resources (consumption tax paid by punters who can't move countries).

That this would shift the burden of taxation from the well-off to the less well-off is just an unfortunate but unavoidable consequence of a globalising world, we're told.

But this is where someone of consequence has said something new and different. In a paper to be released on Wednesday, the head of the Grattan Institute, John Daley, with help from Brendan Coates, argues that the obvious tax we need to raise is not GST but property tax.

He's right, and it's amazing it's taken so long for someone to say the obvious. Real estate is the ultimate immobile resource. A tax on land – with or without the improvements built on it – is very hard to avoid, even by foreign multinationals. It's also highly "efficient" in the economists' sense that it does little to distort people's behaviour. It doesn't discourage them from working, saving or investing.

Since it's the state governments that do most of the spending on health and education – and Abbott still has on the books his plan to cut his budget deficit by reducing federal grants for public hospitals and schools by $80 billion over a decade starting in 2017 – it's appropriate that the tax would be levied by the each of the states, which would keep the proceeds.

Politically, I don't imagine voters would view the prospect of higher property tax with any less hostility than they'd view higher GST. But there's one big difference: increasing property tax would much fairer.

GST is "regressive" – it takes a higher proportion of low incomes than high incomes – whereas property tax is "progressive", hitting the rich harder than the poor. It's actually a tax on one of the main forms in which we keep our wealth.

At present we pay three taxes on property: local government rates, stamp duty when properties are bought and land tax on property other than the family home.

Daley proposes leaving these taxes unchanged while adding a new "property levy" imposed on all property, including owner-occupied homes. The levy would be applied to the same tax base as used for local rates.

He estimates that an annual levy of just $2 for every $1000 of unimproved land value, or $1 for every $1000 of improved value (land plus building), would raise about $7 billion a year.

A homeowner would pay a levy of $772 a year on the median-priced Sydney home, valued at $772,000, or $560 a year on the median-priced Melbourne home, valued at $560,000.

What would we get for that? Mainly, more healthcare, giving us longer lives and less infirmity. Not a bad deal.

Lower dollar boosts services exports

Did you know that when the value of our dollar falls, imports become dearer? When the Business Bible learnt this last week, it got so excited it led the paper with the news.

Every smarty knows that the economic turmoil in Greece and China must spell bad news for us, so when the turmoil caused the Aussie dollar to fall below US75¢, this was obviously the start of the badness.

Apparently, it means the "global purchasing power" of Australian households has fallen. Who knew?

Immediately, our ever-vigilant media sprang into action to determine which purchases were likely to be more expensive. Don't you love the way the media can find the downside in any piece of economic news?

The fact that for months the nation's macro-economists and many of our business people have had their tongues hanging out, thirsting after a lower exchange rate, was something no one considered worth mentioning.

Nor that Reserve Bank governor Glenn Stevens' wish to see the dollar fall to US75¢ had finally come true.

It's true that if you view the position solely from the perspective of consumers, a higher dollar is good news and a lower dollar is bad.

However, from the perspective of Australia's trade-exposed industries and their employees, it's the other way around.

A high dollar means you get fewer Aussie dollars for anything you export, whereas the imports you compete against in the local market are now cheaper than they were.

So a higher dollar means Australian tradeable industries suffer a loss of international price competitiveness, which almost always leads to them reducing their production and their job opportunities.

In other words, a higher dollar has a contractionary effect on economic activity (which at least has the advantage of reducing inflation pressure). And that's been our story since the mining boom caused the Aussie to appreciate so strongly.

However, with mineral commodity prices having been falling since mid-2011 and mining construction projects winding up since the end of 2012, the dollar finally began falling back; though, thanks to the advanced economies' resort to "quantitative easing" (creating money), not by as much as the fall in commodity prices implied should happen.

It follows that a lower dollar has an expansionary effect on economic activity. Since our exporters now get more Aussie cents for each US dollar they earn, they're able to export more. And, since imports are now more expensive to their domestic customers, they're able to recapture a larger share of the local market.

The consequence is that our tradeable industries increase their production and the job opportunities they provide.

In our attempts to explain why relatively strong growth in employment – particularly since the start of this year – has caused the official unemployment rate to stay steady at 6 per cent, you'd have to give the lower dollar a fair bit of the credit.

That's particularly evident in the strong growth in employment in the services sector and in exports of services. Historically, services were regarded as non-tradeable, but globalisation and advances in transportation, telecommunications and digitisation are making that less true every year.

The tradeable services sector's improved price competitiveness comes at a time when Asia's middle-class is growing in size and income, with its consumption preferences shifting towards Western goods, services and destinations.

No service industry better demonstrates the lower dollar's beneficial effect on production and jobs than tourism: an industry where import replacement is just as important as exporting. The lower dollar not only attracts more foreigner visitors, it encourages Australians to holiday at home rather than abroad.

Estimates from Paul Bloxham, of HSBC bank, show spending on tourism accounts for about 3 per cent of gross domestic product, with about a third of this coming from foreign tourists.
The industry employs more than 500,000 people.

Overall, the value of tourism exports reached $14 billion in 2014, up 8 per cent. Tourist arrivals from China over the year to May were up 21 per cent on the previous year, Bloxham says. Chinese visits to Oz have increased to 920,000 over the past year, up from 370,000 five years ago.

Turning to education exports, Bloxham says international student enrolments reached a new high of almost 147,000 at the start of this year. Last year, the value of education exports reached $17 billion, surpassing the previous record in 2009.

And Joe Hockey has reminded us that the value of all services exports over the year to March was up 8 per cent, their fastest growth since 2007.

So if the fallout from the present international turmoil involves further falls in the Aussie, don't let anyone tell you it's a bad thing.
