Slowly, economists are revealing the weaknesses in their theories

Economics is changing. It’s relying less on theorising about how the economy works, and more on testing to see whether there’s hard empirical (observable) evidence to support those theories.

Advances in digitisation and the information revolution have made much more statistical information about aspects of economic activity available, and made it easier to analyse these new “data sets” using improved statistical tests of, for instance, whether the correlation between A and B is causal – whether A is causing B, or B is causing A, or whether they’re both being caused by C.

But another development in recent decades is economists losing their reluctance to test the validity of their theories by performing experiments. Let me tell you about two new examples of empirical research by Australian academic economists, one involving data analysis and the other a laboratory experiment.

We see a lot of calls for reform that take the form: change taxes or labour laws in a way that just happens to benefit me directly, and this will make “jobs and growth” so much better for everyone.

These reformers always convey the impression that the changes they want are backed by long established, self-evident economic principles. And they can usually find professional economists willing to say “yes, that’s right”.

But what gets me is that, when the self-declared reformers get their “reform”, it’s rare for anyone to bother going back to check whether it really did do wonders for jobs and growth. Wouldn’t there be something to learn if it was a great success, or if it wasn’t?

Do you remember back in 2017, when employers were campaigning for a reduction in weekend penalty rates? The retailers and the hospitality industry told the Fair Work Commission that making them pay much higher wage rates on Saturday and Sunday was discouraging some businesses from opening on weekends, to the detriment of the public’s convenience.

If only penalty rates were lower, more businesses would open on weekends, or stay open for longer, meaning consumers would spend more, and more workers would be employed for more hours, leaving everyone better off.

The employers got strong support from the Productivity Commission and some economist expert witnesses. So the commission decided to reduce the Sunday and public holiday penalty rates in the relevant awards by 25 to 50 percentage points, phased in over three years.

Associate Professor Martin O’Brien, of the University of Wollongong’s Sydney Business School, commissioned a longitudinal survey (looking at the same people over time) of about 1830 employees and about 240 owner-managers or employers, dividing the workers between those on awards and a control group of those on enterprise agreements (and so not directly affected).

The economists’ standard, “neo-classical” model of the way demand and supply interact to determine the market price, with movements in the price feeding back to influence the quantity that buyers demand and the quantity sellers want to supply, does predict that a fall in the price of Sunday labour will lead employers to demand more of it.

So what did the survey find? It could find no effect on employment in the retail and hospitality sectors. This is consistent with a growing body of mainly American empirical evidence that, contrary to neo-classical theory, increases in minimum wages have little effect on employment.

But here’s an interesting twist: a majority of employers reported not making the reduction in penalty rates and a majority of employees reported not receiving any reduction.

One explanation for this is that employers didn’t pass on the cuts because they valued staff loyalty and commitment. If so, this fits with the judgment of many labour economists that the relationship between a firm and its workers is far more nuanced than can be captured by the neo-classical assumption that price is the only motivator.

An alternative explanation, however, is that those employers didn’t cut the Sunday penalty rate because they weren’t paying it in the first place.

Turning to the laboratory experiment, it tests the much more theoretical assumption that the behaviour of people engaged in economic activities is guided by their “rational expectations” about what will happen in the future.

Economists have come to care about what people expect to happen because this affects the way people behave, and so affects the future we get. In recent decades, many mathematical models of the macro economy have used the assumption that people form their beliefs about the future in a “rational” way to make the maths more rigorous.

By “rational” they mean that people respond to new information by immediately and fully adjusting their expectations – beliefs – about what will happen to prices, the economy’s growth or whatever. Which is a lovely idea, but how realistic is it?

Dr Timo Henckel, of the Research School of Economics at the Australian National University, Dr Gordon Menzies, of the University of Technology Sydney, and Professor Daniel Zizzo, of the University of Queensland, analysed the results of an experiment conducted by Professor Peter Moffatt, of the University of East Anglia, involving 245 students answering questions.

On receiving each piece of new information, the subjects had first to decide whether to adjust their beliefs and then, if so, by how much. The experimenters found that the subjects reacted very differently.

They found that, in general, people don’t update their beliefs with each new piece of information. And when they do, they tend not to adjust their beliefs by as much as they probably should. In other words, people display a kind of belief conservatism, holding on to a belief for longer than they should.

They found that this conservatism is explained to some extent by people’s inattention – they were distracted by other issues – and to some extent by the complexity of the issue: it was “cognitively taxing”.

It turns out that very few people – just 3 per cent of the subjects – display the rational expectations economists assume in their model-building. Most people’s behaviour, the authors say, is better described as “inferential expectations”.

Now, you may not be wildly surprised by these findings. But, in the academic world, common sense doesn’t get you far. You must be able to demonstrate things the academic way.

Even so, Henckel says that the responses of the experiment’s subjects extend to many parts of life, from the behaviour of investors in the share and other financial markets – this is how bubbles develop – to people’s political convictions, where they hold on to beliefs for far too long, ignoring much contrary evidence.

Indeed, inferential expectations apply even to scientists, who form a view of the world which they will revise or overturn only if there is overwhelming evidence to the contrary. So don’t expect economic modellers to abandon their convenient assumption of rational expectations any time soon.

Budget warning: more rent-seeking won't create jobs

While we wait to see next week’s budget, think about this: economists must shoulder much of the blame for past "reforms" that ended up doing more harm than good. But more of the blame should go to the politicians who allowed lobbying by generous industries to subvert reform and turn it into rent-seeking, or worse.

Lefty academics who bang on about the evils of what they love calling "neoliberalism" seem to see it as some kind of conspiracy between the economics profession and big business.

There’s some truth to this – after all, many economic practitioners work for or produce "independent" consultant reports for big business. But the old rule from politics applies: what may look like a conspiracy is more likely to be just a stuff-up.

The term neoliberalism – a pompous, hipster word only a "problematic" academic could love – conceals more truth than it reveals. The words we used in Australia when this way of thinking became dominant in the 1980s were "economic rationalism" in pursuit of "micro-economic reform" – the very thing Productivity Commission boss Michael Brennan advocated a return to in a speech last week.

The more revealing label, however, is the one preferred by two leading British economics professors, Paul Collier and John Kay, in their new and enlightening book, Greed is Dead: "market fundamentalism".

The economic rationalist thinking that drove extensive economic policy change in the ‘80s and ‘90s took the profession’s ubiquitous neo-classical, demand-and-supply model of how markets work and assumed it was all you needed to know about how the economy worked.

It thus overemphasised the role of competition between "self-interested" (selfish, greedy) individuals, but underestimated the role of co-operation and community spirit and the importance of touchy-feely things such as job security, loyalty and our trust in economic and political institutions in making the economy work well.

The simple model’s assumption that all individuals and firms unfailingly act with full foresight of their best interests implies that government intervention is unnecessary and may well make things worse.

So the greatest crime of the rationalists (including, until far too late, yours truly) was naivety. They saw reforms that worked well in theory and assumed they’d work just as well in practice. In many cases they did work well enough, but in too many others they failed badly.

Unintended consequences abounded, the greatest of which was what I call "the sanctification of selfishness". When the econocrats were planning the removal of import protection they confidently predicted a benefit would be to discourage "rent-seeking" – businesses incessantly lobbying the government for favours when they should be getting on with running their businesses more efficiently.

In reality, rent-seeking has become rife. Since the mid-80s, the Canberra-based lobbying industry must surely have been one of our fastest growing and most lucrative. The economists’ greatest naivety has been their assumption that successive governments would faithfully implement their reform plans while resisting the temptation to do favours for generous mates.

Which brings us to next week’s budget. Recent days have seen big business campaigning for tax breaks, a further shift in the industrial relations power balance in favour of employers, and the removal of "burdensome regulations", all to create jobs.

Trouble is, years of bitter experience have taught us to recognise rent-seeking when we see it. Because economic rationalists have left people with the notion that economic progress is driven solely by self-interest, the rich and powerful now see themselves as justified in demanding that the economy be re-organised in ways that facilitate their efforts to get richer and more powerful.

Among the various micro-economic reforms advocated last week by the Productivity Commission’s Brennan as ways of speeding up the recovery were: removing rigidities in the labour market, streamlining the approvals process for new businesses and improving the “culture” of regulators.

I have no doubt there are plenty of anachronistic, pettifogging, cumbersome provisions of industrial relations law that both sides could readily agree to remove. But I doubt that’s what the employers are seeking. They want their quid without any quo.

Equally, I don’t doubt that much could be done to minimise the time-wasting involved in the regulation of business, without compromising other public policy goals. But too often removing "green tape" is code for sacrificing long-term protection of our environmental assets in favour of letting a few developers temporarily create a few hundred jobs while they build some highly automated mining project.

And while the culture of pushing people around at Centrelink or the local council should definitely be corrected, the last time the pollies went down this road they left the banking and corporate regulators with the clear impression that what they wanted was a buddy-buddy culture. The banks concluded that, for them, obeying the law was optional, and we all remember what happened next.

They should make benefiting you the goal of economics

I was reading yet more about the troubles besetting the rich economies when it struck me: we’d do a lot better if our politicians and their advisers just managed the economy in ways that gave first priority to benefiting the ordinary people who constitute it.

The bleeding obvious, you say? Well, of late, not so you’d notice. Just what we’ve always been doing, the pollies and economists say? Again, not so you’d notice. Too simple? Not if you do it right.

Economics is the study of “the daily business of life” – going to work to earn money, then spending that money. If so, the economy is nothing more than all those who work (paid or unpaid) and consume, which is all of us.

The fact that we are the economy means it’s actually our economy. So all the other players – politicians, economists, even business people – are there to serve our interests. Rather than becoming alienated from the process, we should be holding them to account.

During the past 30 or 40 years of what it’s now fashionable to call neo-liberalism, we were acting on the theory that the best way to benefit all Australians was to reduce the role of government in the daily business of life and give freer rein to businesses.

This indirect approach didn’t work well. We gave our bankers and business people greater freedom from government regulation, but they abused our trust. The lenience of regulators has seen business become remarkably lawless. Too much of the extra income the economy has generated has gone to the very highest income-earners, leaving too little going to middle and lower income-earners.

This era of “economic rationalism” and “microeconomic reform” has ended, leaving Scott Morrison with much damage to clean up. Meanwhile, many voters are disillusioned and distrustful of both main parties, and are turning elsewhere to populists such as Pauline Hanson, who not only have no answers to the problems that bother us, but also seek our support by blaming our troubles on unpopular scapegoats – Muslims, city-slickers etc.

The economic rationalists’ solution to misbehaving businesses, caveat emptor – let the buyer beware – is good advice but, in the modern complex world, it’s impractical. There aren’t enough leisure hours in the day for us to spend most of them checking that all the businesses we deal with aren’t overcharging us or taking advantage of us in some way, and our employer isn’t underpaying us.

So why don’t governments cut to the chase and simply make treating us in such ways illegal? And when doing so is already illegal – as it usually is – why don’t they resume adequately policing those laws?

Something almost everyone craves in their lives, but politicians and economists long ago lost sight of, is a high degree of security. We want the security of owning our own homes and we want security in our employment.

And yet we’ve allowed home ownership to become unaffordable to an increasing proportion of young people. Why? Because we’ve put the interests of existing home owners ahead of would-be home owners. We could fix the unaffordability problem if we were prepared to put the interests of the young ahead of the old.

Some degree of flexibility in the job market is a good thing provided it works both ways. Under economic rationalism, the goal was more flexibility for employers without any concern about what this did to the lives of casual workers mucked about by selfish and capricious employers.

It’s good that part-time jobs are now available for those who want one – students, parents of young children, the semi-retired – but we could do more to make part-time jobs permanent rather than casual.

Many young people worry that we’re moving to a “gig economy” in which most jobs are non-jobs: short-lived, for only a few hours a week and badly paid, with few if any benefits.

I don’t believe we are moving to such a dystopia, mainly because I doubt it would suit most employers’ interests to treat most of their employees so shabbily. But, in any case, the way to avoid such a world is obvious: governments should make it illegal to employ people on such an unacceptable basis.

And governments will do that as soon as it’s the case that not to do so would cost them too many votes. That is, we have to make democracy work for the masses, not just the rich and powerful.

Of course, the security many of us would like is to live in a world where nothing changes. Sorry, not possible. Economies, and the mix of industries within them, have always changed and always will – often for reasons that, though they disrupt the lives of some people, end up making most of us better off.

New technologies are a major source of disruptive, but usually beneficial, change. Another source of disruptive change is the realisation that certain activities are bad for our health (smoking, for instance) or for the natural environment (excessive irrigation and land clearing, burning fossil fuels) and must be curtailed.

Adversely affected interest groups will always tempt governments to try to resist such change – at the ultimate expense of the rest of us. The right answer usually is for change to go ahead, but for governments to help the adversely affected adjust. Just what we haven’t been doing.

Confessions of a pet shop galah: much reform was stuffed up

As someone who, back in the day, did his share of being one of Paul Keating’s pet shop galahs – screeching "more micro reform!" every time they saw a pollie – I don’t cease to be embarrassed by the many supposed reforms that turned into stuff-ups.

My defence is that at least I’ve learnt from those mistakes. One thing I’ve learnt is that too many economists are heavily into confirmation bias – they memorise all the happenings that affirm the wisdom of their theory, but quickly cast from their minds the events that cast doubt on that wisdom.

Well, let me remind them of a few things they’d prefer to forget.

Of course, it’s not the case that everything done in the name of "micro-economic reform" was wrong-headed. The floating of the dollar was an unavoidable recognition that the era of fixed exchange rates was over. And the dollar’s ups and downs have almost always helped to stabilise the economy.

The old regulated banking system wasn’t working well and had to be junked. With the rise of China in a globalising world, persisting with a highly protected manufacturing sector would have been a recipe for getting poorer. Nor could we have persisted with a centralised wage-fixing system or a tax system that failed to tax capital gains, fringe benefits and services – to name just a few worthwhile reforms.

Many privatisations were justified – the government-owned banks, insurance companies and airlines – but the sale of geographic monopolies (ports and airports) and natural monopolies (electricity and telephone networks) was a step backwards, mainly because governments couldn’t resist the temptation to maximise the sale price by preserving the businesses’ pricing power at the expense of consumers.

The conversion of five state monopolies into the national electricity market proved a monumental stuff-up at all three levels: generation, transmission and retail. It quickly devolved into an oligopoly with three big vertically integrated firms happily overcharging consumers at every level, with collateral damage to the use of carbon pricing in reducing greenhouse gas emissions.

We’ve learnt that “markets” artificially created by governments and managed by bureaucrats are – you wouldn’t guess – hugely bureaucratic, with the managers susceptible to “capture” by market players. The gas market has also been an enormous stuff-up, threatening the survival of what remains of Australian manufacturing.

The ill-considered attempt to treat schools and TAFEs and universities as being in some kind of market, where fostering competition between them and paying teachers performance bonuses would spur them to lift their performance, proved an utter dud.

Had the harebrained plan to deregulate uni fees not been stopped, it would have made even worse the chronic disorientation of the nation’s vice chancellors on what universities are meant to do and why they’re doing it. Lesson: trying to turn non-market parts of society into markets, while blithely ignoring all the obvious reasons such "markets" would fail, is a fool’s errand.

Which brings us to the half-baked idea of trying improve the provision of taxpayer-funded services by making their delivery “contestable” by for-profit providers. It's been an expensive failure pretty much everywhere it’s been tried: childcare, employment services, vocational education and training, and aged care (see present royal commission), not to mention privately run prisons and offshore detention centres. How long will it be before we’re having a royal commission into the abuses of the largely outsourced national disability insurance scheme?

Why have so many reform programs ended so badly? Partly because of the naivety of econocrats and other proponents of "economic rationalism". They had no notion of how far the grossly oversimplified neo-classical model of markets they carry in their heads misrepresented the big bad real world.

And many of them, having spent their working lives solely in the public sector, had no idea of how wasteful or bureaucratic the supposedly rational private sector could be. Actually break the law if they thought they wouldn’t get caught because corporate law-breaking wasn’t being policed? Sure. Rip off the government because the bureaucrats wouldn’t notice? Love to.

But there’s another reason so many reforms blew up. Because naive econocrats failed to foresee the way reforms intended to leave consumers or taxpayers better off could be hijacked by Finance Department accountants looking to cut government spending and produce "smaller government" by whatever expediency possible (see uni fee deregulation) and politicians looking to win the approval of big business or to move money and influence from the public sector column (them) to the private sector column (us).

Lesson: if a venal politician can find a way to sabotage micro-economic reform to their own advantage, they will.

How we could revive faith in democracy

How much is our disillusionment with politicians, governments and even democracy the result of our pollies’ 30-year love affair with that newly recognised mega-evil “neoliberalism”?

To a considerable extent, according to Dr Richard Denniss, of the Australia Institute, in the latest Quarterly Essay, Dead Right.

I’m not sure I’m fully convinced by his argument, but it’s a thought-provoking thesis that’s worth exploring.

Like “globalisation” in the 1990s, neoliberalism has become the all-purpose political swearword of the 2010s. Anything economic that you don’t approve of can be condemned as neoliberalism.

But Denniss provides some more specific attributes. “The intellectual core of neoliberalism is the idea that the profit motive of companies, combined with consumers’ ability to choose the product that suits them best, will result in the best possible social and economic outcomes,” he says.

Implicit in this is the belief that government intervention in markets is always suspect and should be reduced to a minimum, just as taxation is an onerous “burden” which must be reduced if we are to prosper.

Dennis argues that neoliberalism hasn’t just involved much deregulation, privatisation, outsourcing of government services and cuts in government spending, it’s also changed our culture – the way we think about politics and political issues.

Its focus on the individual has sanctified selfishness, releasing people from the restraints of solidarity with the rest of the community and legitimating the lobbying mentality. We’re all free to press our own interests on the government, and if that means I extract more than you do, that just proves I worked harder than you.

But the greatest cultural change, according to Denniss, is the belief that economic issues outweigh all other considerations. “The trick of neoliberalism was to convince the public that it is the economic dimension of big issues that we must focus on,” he says.

“Past generations . . . did not see the need to delay all significant debates about the shape and direction of their society until tax and industrial relations policies were optimised according to specific principles understood by a tiny proportion of the population.”

Denniss says we no longer talk about the inherent value of educating our children, but of the increase in skills and productivity that their education will bring to the economy.

A big part of this is the obsession with maximising the growth of the economy – or, in Malcolm Turnbull’s more enticing packaging, Jobs and Growth.

“After 27 years of continuous economic growth, it is inconceivable that the thing Australia needs most is to ‘grow our economy’ some more.

“What we really need is to rebuild trust in our institutions and confidence in our country. We need to debate far more specific and important national goals, and then show ourselves that when we work together we can make things better. We have done it before and other countries are doing it right now.”

What if Australian parliaments stopped trying to fix the industrial relations system or the tax system for a few years, and focused instead on things that Australians really care about?

“For 30 years Australians have been told that what is good for gross domestic product is good for the economy, and hence for the country. But that is like saying that the more money a family earns, the happier the children will be.

“It is the shape of our economy that determines our wellbeing, not its size. Spending $1 billion subsidising the Adani coalmine will create economic activity [and jobs], but so will spending that money promoting Australian tourism or improving Sydney’s pubic transport.

“The important question isn’t whether a project will ‘create activity’, but whether a project will make Australia a better place or not.”

Like waiters in a restaurant, says Denniss, politicians and bureaucrats are not there to tell us what we must order, but to show us the menu and explain the specials.

So one of his proposals is to replace the Productivity Commission with a national interest commission, to provide both governments and the public with broad advice on the advantages (as opposed to benefits) and disadvantages (as opposed to costs) that, say, a major project or a universal basic income, might entail.

The opposite of the narrow economic agenda of neoliberalism isn’t a progressive economic reform agenda, Denniss says, it’s the re-establishment of a broad debate about the national interest.

“After 30 years of hearing that politicians, government and taxes are the things that ruin the economy, it is time for the public to hear and see that politicians, government and taxes are the foundations on which prosperous democratic nations are built.”

There are dozens of popular things that state and federal governments could get on with that would make Australians happy, make Australia a nicer place to live and, most importantly, show the Australian public that the decisions made by parliament do make a difference.

Such as? “Bans on political donations, the establishment of strong anti-corruption watchdogs, reform to parliamentary entitlements, higher taxes on annual incomes over $1 million, closing loopholes that allow companies to pay billions in dividends and nothing in tax, legalising marijuana, banning poker machines, and preserving all existing parks from property development.”

The world is full of alternatives and choices, Denniss concludes. “Neoliberalism’s real power came from convincing us that we had none. We do, and making them is the democratic role of citizens – not the technocratic role of economists, nor that of any self-serving elite."

Economic rationalists regroup under populist attack

Reading the Productivity Commission's grand plan to "shift the dial" on micro-economic reform gives me a feeling of deja vu all over again.

When I started in this business in the mid-1970s, macro-economics had become a pitched battle between Keynesians and monetarists. It took years for a resolution of that conflict to emerge.

The monetarists didn't win the war, but they did win a lot of battles, and management of the macro economy was changed forever.

Today's great conflict in economics comes in the aftermath of the global financial crisis, as politicians in all the advanced economies abandon the "neoliberal consensus" under pressure from the populist revolt against privatisation, deregulation, austerity and all the rest.

You could say the global rethink of economics began immediately after the crisis, but it's just in the Productivity Commission's latest report proposing a "new policy model" for future change that we see our local "thought leaders" among economic rationalists shifting to an agenda that responds to the criticism of the old approach and proposes a new set of reforms aimed at improving productivity while giving voters far less cause to object.

Why so few commentators have perceived the significance of this "dial shift" is hard to fathom.

Read the report and it sticks out like organ stops. For some years since the crisis, the bosses of the International Monetary Fund, the Organisation for Economic Co-operation and Development, and even the Bank of England have said we need economic growth to be more "inclusive".

Now the Productivity Commission agrees and has reshaped its reform agenda accordingly.

The old agenda accepted the conventional wisdom that economic efficiency and equity (fairness) were in conflict. Since the crisis, however, economists at the fund and the OECD have been producing evidence that increasing inequality inhibits economic growth.

Now our commission agrees, arguing that its proposed shift in the reform dial will avoid "too great a dispersion in incomes, given evidence that this can, in its own right, adversely affect productivity growth".

In shifting reform priorities from changing tax incentives, moving the balance of wage-setting power in favour of employers, deregulating and privatising, to reforming healthcare, education and cities, the commission is attempting to humanise reform.

In setting its main priorities as improving the quality of services delivered to patients, students and commuters, the commission has made ordinary punters the main beneficiaries. What's that if it's not more "inclusive"?

Low and middle-income earners would be the chief winners because the better-off are better able to buy their way out of bad medical treatment, bad teaching and long commutes.

And get this: more efficient and effective healthcare, teaching and cities bring intrinsic benefits to the lives of ordinary people, whether or not they ever "shift the dial" of the measures of productivity that the commission takes so literally (which they quite possibly won't).

The commission's "new policy model" is far better fitted to an economy ever-more oriented to the services sector, and to an economy where the value of knowledge becomes more apparent as each year passes.

What seems to have bamboozled the commentators is the notion that nothing on the commission's new reform agenda is particularly new.

True, but silly. In economics, there's not much that's new under the sun. Sure economists have been rabbiting on for years about the need to reform healthcare and education and – much more recently – "urban economics".

What's new is not the topics but the priority and emphasis they've been given. What's new is sorting through a list of old potential reform topics to find those that tick the efficiency box and the fairness box.

Another uncomprehending reaction has been that many of the specific reforms the commission advocates – road-use charging, for instance – would be politically difficult, and most unlikely to be taken up by the Turnbull government.

True, but beside the point. What's significant is the radical change in thinking about the nature and direction of economic reform, not how long it will take for those reforms to be made.

I've been around long enough to see plenty of politically impossible reforms come to pass.

A more perceptive critique of the "new policy model" is that it takes us straight into territory where the states have as much say as the feds, if not more. No easy country.

And while it's true ordinary voters have much to gain from the new agenda, it's equally true that vested interests in the health, education and city industries have much to lose.

One further lesson from economic rationalism's poor record in recent times is that if you're not game to take on powerful rent-seekers, you won't get far.
