how we caught the economic growth bug, but may shake it off

Do you realise that the great god of mammon, Gross Domestic Product, has really only been worshipped in Australia for 60 years last month? Its high priests at the Australian Bureau of Statistics have been celebrating the anniversary.

Sixty years may see a long time to you, but not to me. And not when you remember that the study of economics, in its recognisable form, started with the publication of Adam Smith’s Wealth of Nations in 1776.

GDP is the most closely watched bottom line of the "national accounts" for the Australian economy.

So what do GDP and the national accounts measure, where did they come from and are they as all-important as our economists, business people and politicians seem to think, or is GDP the source of our problems, as many environmentalists and sociologists seem to think?

What GDP measures can be described in several ways. I usually say it measures the value of all the goods and services produced in Australia during a period.

But because workers and businesses join together to produce goods and services in order to earn income, it’s equally true to say that GDP is a measure of the nation’s income during a period.

And since income is used to buy things, it’s also true that GDP measures the nation’s expenditure (but only after you subtract our spending on imports and add foreigners’ spending on our exports).

Now some qualifications.

GDP measures the value of goods and services bought and sold in the market place, plus the goods and services supplied by governments but paid for by our taxes. This means GDP doesn’t include the (considerable) value of all the goods and services – meals and so forth – produced in the home without money changing hands.

Economists (and economic journalists) make so much fuss about the quarterly ups and downs of GDP – is the economy growing or contracting, is it growing faster or slower? – it’s easy to assume that economic growth is something they’ve always obsessed about.

In truth, it’s a relatively recent preoccupation – suggesting it’s a habit we may one day grow out of. You see this more clearly when you consider the origins of GDP and the national accounts it springs from.

The 60-year anniversary is of the move to quarterly estimates of the growth in GDP in September quarter, 1959. It’s hard to be obsessive about something when you don’t get regular reports on how it’s going.

Fact is, until the Great Depression of the 1930s, economists were preoccupied with studying how markets worked ("micro-economics") and gave little thought to how the economy as a whole worked ("macro-economics"), let alone how fast it was growing.

In his recent history of the federal Treasury, Paul Tilley noted that it was just a department full of bookkeepers until the upheavals of the Depression caused its political masters to ask questions about what they should be doing that it couldn’t answer. That’s when Treasury became macro-economists.

It was the failure of "neo-classical" economics to provide an effective response to the Depression that led to the ascendancy of an Englishman who did have answers, John Maynard Keynes. At the heart of the ensuing the "Keynesian revolution" in economics was the notion that there was such a thing as the macro economy and that it was the responsibility of governments to "manage" that economy, ending its slump and getting workers back to work.

Once you started thinking like that, it became obvious that, to manage the economy effectively, you needed to measure it and track the changes in it over time.

The first economists to start developing a systematic and internally consistent way of measuring the economy, in the early 1930s, were Simon Kuznets in the United States and Colin Clark in Britain. Clark, a disciple of Keynes, moved to Australia in 1938 and spent the rest of his life as an adviser to the Queensland government.

For some years after World War II, our Treasury issued annual, out-of-date estimates of the size of GDP and its components.

The Keynesian economists’ preoccupation then was not with growth as such, but with keeping the economy at "full employment" – in those days defined an unemployment rate of less than 2 per cent – which, admittedly, did require it to be growing pretty quickly. In those days, however, GDP was used more as an aid to the short-run stabilisation of the business cycle – "demand management".

Paul Samuelson’s legendary introductory textbook, first published in 1947, which "brought Keynesian economics into the classroom", didn’t have an entry for "growth" until its sixth edition in 1964.

It was only about then that people became preoccupied with economic growth, as indicated by the growth in GDP.

The critics are right to point out the many respects in which GDP falls short as a measure of human wellbeing. But, though it’s true many people treat GDP as though it is such a measure, it was never designed to be used as such.

I agree with the critics that there’s more to life than economic growth and that politicians and economists should give less attention to growth and more to the many less tangible, less well-measured social factors that also affect our wellbeing.

It’s true, too, that GDP was developed before we became conscious of the need for economic activity to be ecologically sustainable – which the present hellish summer reminds us it certainly isn’t at present. In this sense, GDP is no longer "fit for purpose".

It’s wrong, however, to conclude that continuing growth in GDP is incompatible with ecological sustainability. People say that because they don’t understand what drives the "growth" that GDP measures (hint: improved productivity).

We can have unending growth in GDP and sustainable use of natural resources (which is what the environmentalists care about) by changing the way economic activity is organised – including by getting all our energy from renewable sources.

Government on the cheap leaves us burningly reliant on charity

As the cast were taking their bows at the end of a show before Christmas, one of them stepped forward to say that, as we left, we’d be approached by people with buckets collecting for the NSW Rural Fire Service. Normally I’d reach for my wallet – I’d done so a few weeks earlier when they were collecting for an actors’ charity – but this time I declined.

Like Victoria’s Country Fire Authority, the RFS is staffed by volunteers. Why did they need donations? Presumably, to help cover the cost of needed equipment or incidental expenses. Really? What’s happened to the state government’s cheque book? And don’t I remember hearing that the RFS had had its funding cut?

No one believes every worthy cause should be funded by the government so that private charity becomes redundant. And it’s true the federal government partially subsidises donations by making them tax-deductible. But where do you draw the line between what the government should cover and what can be left to the generosity – or otherwise – of private citizens?

The more I think about it, the more I realise that, as part of their commitment to Smaller Government and lower taxes, governments have been quietly shifting the dividing line between what the government pays for and what should depend on charity.

All governments have been doing it. State governments, for instance, have long left country (but not city) fire-fighting to volunteers. And have long underfunded the upkeep of public schools, believing parents and citizens can be left to make up the shortfall. But it’s been a particular trick of the federal Coalition government as it struggles to return its budget to surplus when there are expensive, vote-buying tax cuts to be covered.

If you’re wondering why, despite his contrition at having taken an overseas break his spin doctors tried to keep secret, and his freely dispensed “thoughts and prayers”, Scott Morrison remained adamant for so long that all that was needed was already being done to help the firefighters, it’s because he knows that too much generosity on the feds’ part could see his precious budget surplus whittled down to nothingness.

Since its election in 2013, this government has been insistent that the budget should be returned to surplus by cutting government spending, not by explicit increases in taxes (hidden tax increases caused by bracket creep are okay, of course, because the punters don’t notice ’em).

Its first budget in 2014 was a long-term plan to improve the budget by what the bureaucrats call “cost-shifting”. Much of the cost of health and education was to be shifted onto the states’ budgets. Some was to be moved to your household’s budget via the $7 charge for visits to the doctor.

That budget was so badly received most of those plans were reversed. But Finance Minister Mathias Cormann and his accountants have continued to limit the growth in government spending by penny-pinching in ways that voters wouldn’t notice or object to.

They’ve got welfare dependency to “its lowest level in 30 years” not by getting the unemployed into jobs, but by using petty excuses to suspend people’s dole payments. How do these unfortunates live without money to live on? They fall back on their families or go cap-in-hand to the Salvos or Vinnies. Get it? The feds are cost-shifting to charities – the same community groups whose grants they’ve cut back.

According to a recent survey of its members’ staffs by the Australian Council of Social Service, 76 per cent of staff dealing with housing the homeless reported an increase in demand, as did 71 per cent of those providing financial counselling and support (aka money). Respondents to the survey said the unmet demand naturally had adverse impacts on the community. Where people fall through the cracks they can end up in hospitals or the justice system (cost-shifting to the states).

I’ve been reading about how many small country towns are relying on newly formed charities for their supply of water. More broadly, the desire to limit government spending encourages politicians to ignore reports warning of looming troubles and push problems off into the future. Some of the foreseen problems fail to materialise, but many eventually reach crisis point and can no longer be ignored.

The aged care royal commission is revealing the shocking results of one attempt to keep government small by relying on for-profit providers, underspending on the provision of home-care packages and on policing institutions’ adherence to the rules.

Which brings us back to our truly heroic volunteer firefighters. Morrison’s reluctant decision to pay them $300 a day for a maximum of 20 days is the least he can do to acknowledge their loss of income (or annual leave) while serving their communities.

His reluctance – and anxiety to emphasise it’s not a payment of wages – is understandable, however. Behavioural economics is clear that paying people to do what they formerly did without payment can kill the motivation to donate your services for noble reasons. Morrison has stressed that this response to a problem of unprecedented severity shouldn’t be seen as setting a precedent.

Good luck with that. If climate change is making drought, heatwaves and bushfires bigger and more frequent, the horrific events of this summer will become a regular occurrence – meaning the days of leaving bushfire fighting to unpaid volunteers are numbered.

Living in the post-inflation era turns out to be no fun

It’s Christmas shopping time, when the bills mount up and your money never goes far enough. So how come people are saying the inflation rate should be higher? I thought inflation was meant to be a bad thing?

It’s a good question when one of those people is Reserve Bank governor Dr Philip Lowe. He keeps saying we need to get unemployment lower and inflation back up into the 2 to 3 per cent target range. (At last count the annual rate of increase in consumer prices was "only" 1.7 per cent. I can remember when, for a brief period in the 1970s, it was 17 per cent.)

The short answer is that Lowe doesn’t see higher prices as a good thing in themselves. Rather, he sees them as a means to an end. Or better, as a symptom or by-product of something that is a good thing.

Why do prices rise? Because the demand for goods and services – the desire to purchase them – is growing faster than the supply of them – our businesses’ ability to produce them. So the rate of price inflation is a symptom or sign of strong demand.

And strong demand for goods and services is a good thing because it means the economy is growing and so is employers’ need for workers to help produce more goods and services. Employment increases and unemployment falls.

So Lowe wants to see higher prices simply because they’re a means to the end of lower unemployment. What’s more, increased employer demand for labour relative to its supply makes labour – particularly skilled labour – scarcer and so puts upward pressure on its price, otherwise known as wages.

And, as he’s often said, Lowe would like to see employers paying higher wages than they are, because consumer spending – consumer demand – is so weak at present mainly because wages are hardly growing faster than consumer prices, and real wages are the main thing that drives consumer spending.

All that make sense? Good – because now I’ll give you the more complicated answer. Surely, although strong demand is good for the economy, it would be better if supply was just as strong, meaning we could have growth in jobs and living standards without any inflation?

That makes sense in principle, but not in practice. The managers of the macro economy believe we need some inflation, though not too much. For two reasons. First, though you’ll find this hard to credit, economists are sure our consumer price index (like other countries’ CPIs) overstates inflation.

That’s because the official statisticians are unable to pick up all the cases where prices rise not simply because the firm’s costs have risen, but because the quality of the product has been improved. If so, aiming for a measured inflation rate of zero would require you to crunch the economy hard enough to make actual inflation less than zero – that is, prices would be falling.

The second reason is that sometimes, when the economy is growing too strongly, wages rise too much, prompting firms to lay off workers. Trouble is, workers hate having their wages cut. But if you’ve got a bit of inflation in the system, you can cut wages in real terms simply by skipping an annual pay rise, which workers find less unpalatable.

When the Reserve Bank set its target for inflation in the early 1990s, it settled on 2 to 3 per cent a year ("on average over the medium term"). It thought such a range would overcome both problems and insisted such a target range constituted "practical price stability".

But things in our economy and all the advanced economies have changed a lot since the 1990s. Demand has been chronically weak relative to supply since the global financial crisis and, in consequence, inflation rates have been below-target everywhere.

Some people have suggested we move to a lower, more realistic target range, but Lowe has resisted, arguing that to do so would lower firms’ and workers’ expectations about inflation, making our weak-demand problem even worse. He may be right.

But now try this thought. Inflation is 1.7 per a year, while wages are growing by 2.2 per cent and workers aren’t at all happy. I’ve had several top economists agree with my contention that, if we could wave a magic wand and raise both inflation and wages by, say, 2 percentage points, so that wages were growing by 4.2 per cent, workers would be a lot less discontented.

Why? Because of a phenomenon that economists used to talk about a lot in in the 1960s, but rarely mention today, called "money illusion". People who aren’t economists keep forgetting to allow for inflation. If so, the era of very low inflation isn’t proving to be much fun.

Don’t bank on budget surpluses this year or in future

This week’s mid-year budget update has changed the fiscal outlook markedly. It’s now a lot clearer that neither in this financial year nor those following is a budget surplus assured.

Whether he knows it or not, by staking so much of his political and economic credibility on getting back to surpluses, Scott Morrison has taken an enormous gamble. When the reality of this “courageous decision, minister” finally gets through to him, I won’t be surprised to see him perform a backflip to go down in history.

Since the election of the Coalition in 2013, there’s been a great debate about the causes of our economy’s continuing sub-par performance. While some economists have argued its roots lie mainly in changes to the structure of the economy (and thus lasting), the econocrats have insisted the causes are cyclical and thus temporary.

So Treasury and the Reserve Bank have gone on, budget update after budget after budget update, predicting that, although the latest indicators show the economy remaining sub-par, it will soon return to the trend growth we were used to before the global financial crisis.

Until now. The mid-year update represents the first stage in the econocrats’ quiet shift from cyclical to structural as the predominant cause of the economy’s weakness. And the first hint it was on its way came in late November, when Reserve Bank deputy governor Dr Guy Debelle pronounced that annual wage rises of between 2 and 3 per cent were “the new normal”.

By far the most significant revisions to the budget forecasts were made to annual growth in the wage price index. With the actual for last financial year coming in at 2.3 per cent rather than 2.5 per cent, the prediction for this year was cut by 0.25 percentage points to 2.5 per cent. The following three years were cut by 0.75 points to 2.5 per cent, by 0.75 points to 2.75, and by 0.5 points to 3 per cent.

This would be the main factor explaining why, after consumer spending grew by just 1.2 per cent over the year to September, the forecasts for consumer spending were cut by 1 percentage point to 1.75 per cent for this financial year, and by 0.5 points to 2.5 per cent for next year.

Despite offsetting changes to other components of gross domestic product, these major downward revisions to wages and consumer spending do most to explain why the forecast for real GDP growth for this financial year was cut by 0.5 percentage points to 2.25 per cent – but nothing to explain why growth the following year was kept unchanged at 2.75 per cent (but see below).

The major cuts to wages and consumer spending forecasts do most to explain why, after just eight months, the government’s been obliged to slash the budget’s estimate of tax collections and other revenue over the budget year and the three “forward estimates” years by a total of – amazingly — $33 billion.

Partly offsetting this, however, are its net cuts in estimated government spending over the four years of $11.5 billion. How is this possible when, in the time since the budget, the government has announced additional spending of $8.2 billion over the period on drought support, aged care and accelerated spending on infrastructure?

It’s possible because the lower predicted growth in wages and inflation will save the budget money on indexed welfare payments and, more particularly, because the fall in long-term interest rates will save it big money on interest payments on the net public debt. An expected gross saving on the spending side of $19.7 billion.

See what a difference less optimistic forecasts for the economy make to the budget?

Slashing revenue estimates by $33 billion, less the net saving on spending of $11.5 billion, means the expected budget surpluses over the four years have been slashed by $21.5 billion, from $45 billion to $23.5 billion. The expected budget surpluses have almost halved in the space of eight months.

This means the expected surplus for this financial year has been cut to $5 billion, or just 0.3 per cent of annual nominal GDP. Do you see how, in a budget worth $500 billion, such a small sum could disappear with just the smallest overestimate of revenue or underestimate of spending?

It’s the same for the revised predictions for surpluses in the following years: $6 billion (0.3 per cent of GDP), $8 billion (0.4 per cent) and $4 billion (0.2 per cent).

As former top econocrat Dr Mike Keating has argued, with no fall in unemployment expected until a modest improvement in 2021-22, the revised forecasts offer no convincing reason why annual wage growth will recover from its present rate of 2.2 per cent to a projected 2.75 per cent in 2021-22 and 3 per cent the year after.

Amazingly, the budget update papers imply this will happen because the budget’s projection methodology requires it to. Same with the return to (pre-crisis) trend GDP growth of 2.75 per cent next financial year. (This is a sign the econocrats have some way to go in fully accepting that structural changes will stop us ever returning to the “old normal”.)

But just as hard to believe as the out-year growth projections is the budget’s assumption that, having so far succeeded in limiting average real growth in government spending to 1.8 per cent a year, the government will now limit it to 1.3 per cent a year over the next four years.

As Keating has noted (and peak welfare group ACOSS’s Dr Peter Davidson before him), this implies real government spending per person will actually be falling.

Unsurprisingly, the Parliamentary Budget Office has warned it’s hard to believe such a degree of restraint could be maintained over such a long time.

Even Morrison’s secret weapon, aka hollow log – the budget’s highly conservative assumption on future world iron ore prices – rests on a gamble that iron ore prices will remain abnormally high. It would be so much less risky just to have some fiscal stimulus.

Orana to Christmas, summer and the chance to go bush

Out on the plains the brolgas are dancing
Lifting their feet like war horses prancing
Up to the sun the woodlarks go winging
Faint in the dawn light echoes their singing
Orana! Orana! Orana to Christmas Day

To me one of the nicest bits of Christmas is a chance to sing the Australian carols of the old ABC’s William G. James, including Carol of the Birds. Orana, by the way, means welcome.

I don’t like to boast, but one of my achievements this year was to see a brolga. Several, in fact. Flying rather than dancing but, even so, one to cross off my bucket list. I’ve also seen jabirus, magpie geese, comb-crested jacana, osprey, white-bellied sea eagles, red-tailed black cockatoos and crocodiles, fresh and salty.

I’ve also seen Timorese ponies, Asian buffalo and – more surprising – Indonesian banteng cattle. By now the banteng are endangered in Indonesia, but going strong in northern Australia.

All during a 12-day tour of Arnhem Land, bouncing along unsealed roads in a truck converted to a bus, to visit remote Aboriginal communities (complete with permits) and cave paintings. An unforgettable experience, one moneyed Baby Boomers should consider before they jet off on yet another exploration of other people’s homelands.

Actually, I sometimes wonder whether the day is coming when – because of the damage it does to the atmosphere – we will look back with amazement and envy on the relatively brief golden age when flying for tourism was not only permitted but dirt cheap, so we roamed the globe whenever we could get away.

It’s a terrible thought. Let’s hope it never happens, thanks to some technological advance in aircraft fuel. But while it lasts, let’s not forget what a privileged generation we are.

But what of ecotourism? Is it as virtuous as we wilderness wanderers like to imagine, or will the new age puritans put the kybosh on that, too?

Well, I’ve been checking what the academic experts are saying – courtesy of my second-favourite website, The Conversation – and, though you can find the killjoys if you look, I think ecotourism gets a qualified tick.

It’s true that, in an ideal world, we’d all stay at home admiring nature from afar and insisting the politicians keep the outback – and other continents’ backblocks – locked up and in pristine condition. Where damage had already been done, we’d happily pay high taxes to compensate farmers, miners and tour operators for closing their businesses, and to restore the land to its former state.

No, not going to happen. Those who live in far-flung parts aren’t going to renounce the material ambitions that drive the rest of us. They’ll continue finding ways to make a buck. If so, ecotourism – whatever its downsides – will do a lot less harm than many other ways for bushies to earn a living.

Dr Guy Castley and two other researchers at Griffith University find ecotourism can contribute to conservation or adversely affect wildlife, or both. Attitudes of local communities towards wildlife influence whether they support or oppose poaching. Income from ecotourism may be used for conservation and local community development, but not always.

But for seven of the nine threatened species they studied – the great green macaw in Costa Rica, Egyptian vultures in Spain, hoolock gibbons in India, penguins, wild dogs and cheetahs in Africa, and golden lion tamarins in Brazil – ecotourism provided net conservation gains.

This was achieved through establishing private conservation reserves, restoring habitat or by reducing habitat damage. Removing feral predators, increasing anti-poaching patrols, captive breeding and supplementary feeding also helped.

For orang-utans in Sumatra, however, small-scale ecotourism couldn’t overcome the negative effects of logging. And for New Zealand’s sea lions, ecotourism only compounded the effects of intensive fishing because it increased the number of pups dying as a result of direct disturbance at sites where the sea lions came ashore.

Michele Barnes and Sarah Sutcliffe, of James Cook University, studied the effect of a shark education and conservation tour off the coast of Oahu, Hawaii. Sharks are crucial to our marine ecosystems, yet many shark populations are in decline because of fishing (particularly for shark-fin soup), fisheries bycatch, habitat destruction, and climate change.

Sharks have a PR problem. They are feared by many, demonised by the evil media, treated as human-hunting monsters, and cast as the villains in blockbuster movies. In many places, governments cull sharks in the name of beachgoers’ safety.

The researchers found that the program gave participants significantly more knowledge of the ecological role of sharks and a more favourable attitude towards them. It also had a significantly positive effect on people’s intentions to engage in shark conservation behaviour. This remained true even after allowing for the participants’ greater initial positive attitudes towards sharks than the public generally.

Even when not off somewhere exotic, my family almost always ends up holidaying in or near some national park. But what about all the damage done to parks to accommodate the needs of tourists?

Dr Susan Moore, of Murdoch University, and others from Southern Cross University, argue sensibly that parks need visitors to get vital community and political support.

“We need people in parks because people vote and parks don’t,” they say. “Strong advocacy from park visitors for environmentally friendly experiences, like wildlife viewing, photography, hiking, swimming, canoeing and camping, can counterbalance pressures for environmentally destructive activities such as hunting and grazing.” Amen to that.

Letting things get worse so we're well placed to fix them later

If you've been feeling the pinch of a massive mortgage and minuscule pay rises and resolving to keep your spending tight this Christmas, Scott Morrison has good news. You will be relieved to hear the federal budget is still on track to reach a surplus this financial year and stay in surplus as far as the accountants' eyes can see.

Although many economists have been panicking over the economy's weak state – and the panickers were joined this week by the International Monetary Fund – Morrison is sticking to his resolve to keep his foot on the budget brake rather than move it to the accelerator.

This, his Treasurer Josh Frydenberg assured us in the mid-year budget review, will bring great
economic benefits, providing "the stability and certainty that households and businesses need to
plan for the future, giving them confidence to spend and invest knowing that the government can
keep taxes low and guarantee funding for essential services".

Hasn't worked so far, but it's bound to kick in soon.

Admittedly the economy's growth is weaker than he predicted it would be before the election in
May, so Frydenberg has had to cut the expected surplus this financial year by $2 billion to $5 billion (not all that much in a $500 billion budget) and by $5 billion next year.

This is mainly because the government has been obliged to abandon the confident prediction it has been making throughout its time in office that wage growth would soon return to something much healthier.

The bad news from the update is that Frydenberg is not expecting pay rises to average as much as 3 per cent a year until the second half of 2022 at the earliest.

But if that makes you fear the budget may not stay in surplus for long, Morrison has more good news. Much of the budget's recent strength despite a slowing economy is explained by the huge taxes our mining companies will be paying because a mining disaster in Brazil has pushed the world price of iron ore way up.

The trick is they've built themselves a hollow log. The budget's figuring is based on the assumption that the iron ore price collapses to $US55 a tonne. Should that not happen, Morrison can use the difference to prop up his budget if the panickers are right and the economy stays weak rather than speeding up, as he's sure it will.

On a separate matter, remember the Future Fund, set up in the early years of the resources boom when the Howard government was running budget surpluses so big they were embarrassing? According to Frydenberg's latest figuring, the income from all the shares the fund's money was invested in will account for most of the budget surpluses the government is expecting to run.

Now that's the "responsible fiscal management" we have come to expect of the Coalition. And it must surely comfort you to know that, should the worst come to the worst, the government will be well placed to launch a few life boats. On a user-pays basis, of course.

Your antidote to Frydenberg’s budget-update talking points

At a time when the Prime Minister is refusing to accept that our weak economy needs a boost rather than a drag from the budget, stand by for loads of look-over-there spin from his unfortunate Treasurer Josh Frydenberg when he unveils the mid-year budget update today.

That was Frydenberg’s way of bluffing his way round the news earlier this month that the economy had grown by a disappointing 1.7 per cent over the year to September. So it wouldn’t be surprising to see some of those talking points get another run today.

He started with the line that, despite a result that laughed at his forecasts made only eight months earlier, the economy remains “remarkably resilient in the face of significant global and domestic economic headwinds”.

That’s a spin doctor’s way of saying “it could have been even worse”. Arithmetically true, but cold comfort. Since Frydenberg is boasting about our strong growth in exports, it’s hard to see much evidence of the global headwinds he claims are holding us back. And the domestic headwinds we’re suffering are home-grown and all too evidently a sign of poor economic management.

But Josh has more: “While other major developed economies like Germany, the United Kingdom, South Korea and Singapore have experienced negative economic growth, the Australian economy is in its 29th consecutive year of economic growth.”

Yes, but at present almost all our growth is coming from high immigration-fed population growth, not rising prosperity. As AMP Capital’s Dr Shane Oliver has noted, our annual growth in gross domestic product per person is just 0.2 per cent, compared with America’s 1.4 per cent, Japan’s 1.6 per cent and even the Eurozone’s 1 per cent.

In the first of his look-over-there arguments, Frydenberg boasts that we’ve maintained our AAA credit rating from three leading US rating agencies. Since these agencies’ lapse in ethical standards contributed significantly to the global financial crisis, this isn’t a recommendation I’d be skiting about. Any government that lets those disreputable characters dictate its budget policy lacks the courage of its convictions.

Next, we’ve seen our current account on the balance of payments “return to surplus for the first time in more than 40 years”. Not sure whether this boast is a sign of our Treasurer’s economic illiteracy, or his assessment of ours. Only the same people who think now’s a good time for the budget to take more out of the economy than it puts back – that is, return to surplus – would be foolish enough to think a current account surplus was a sign of economic strength.

It’s actually a sign that business investment is so unusually weak that our households, companies and governments are saving more than is needed to fund our national investment in new productive assets. Our usual current account deficit would be a much better sign of strong investment in future expansion.

Then we’re told that “welfare dependency is at its lowest level in 30 years”. With the unemployment rate at 5.3 per cent and the under-employment rate at 8.5 per cent, that’s not because they’ve all got jobs, it’s because of the government’s greater use of excuses to cut people off the dole and make them reliant on charity for their survival. Talk about reversion to the mean.

In a breathtaking case of Orwell’s Newspeak, Frydenberg claimed “growth has been broad-based with household consumption, public final demand and net exports all contributing to GDP growth”.

This is the very opposite of the truth. Since growth in consumer spending was a negligible 0.1 per cent during the quarter, the vast private sector of the economy actually went backwards, with what little growth we got coming from the much smaller (and despised) public sector and from net exports.

Growth in the September quarter was weaker than expected because Frydenberg’s repeated assurances that his middle-income tax offset would boost consumer spending failed to happen. Talk about chutzpah. He changed his line to “whether spent or saved, the tax cuts are putting households in a stronger economic position, making them more financially secure with more money in their pockets” without a blush.

Finally, it’s the drought’s fault – and you surely can’t blame the government for that. “Farm GDP is 5.9 per cent lower through the year to the September quarter and falling in four of the past five quarters. Rural exports fell by 2.8 per cent in the quarter,” Frydenberg said.

Arithmetically correct, but calculated to mislead. What he hopes you won’t remember is that, these days, agriculture accounts for only about 2 per cent of GDP, meaning the drought shaved only 0.1 percentage points off growth in the quarter, and 0.2 points over the year.

All this is the balderdash we get when pollies give politics priority over policy.

Why the government's forecasts are always way off

Just to warm you up for the mid-year budget update on Monday, let me ask you: why do you think Treasury and the Reserve Bank have gone for a least the past eight years forecasting more growth in the economy than ever transpired?

Kieran Davies, a respected economist from National Australia Bank, has been checking. He says their mistake has been failing to allow for the decline in our “potential” growth rate since the global financial crisis in 2008.

Actually, Davies has checked only the Reserve’s forecasting record, not Treasury’s. But the two outfits use similar forecasting methods and use a Joint Economic Forecasting Group to ensure their forecasts are never very different.

An economy’s “potential” growth rate is the average rate at which its capacity to produce goods and services is growing each year. This is determined by the average rate at which the Three Ps are growing – population, participation (in the labour force) and productivity (output per unit of input).

Sometimes (as now) the economy’s annual demand for goods and services doesn’t grow as fast as its potential to supply those goods and services is growing. This creates an “output gap” of idle production capacity, including unemployed and under-employed workers.

When demand picks up, the economy can grow faster than its potential growth rate for a few years until the idle capacity is fully taken up and the output gap has disappeared. Once that’s happened, the potential growth rate sets the speed limit for how fast the economy can grow. If demand’s allowed to grow faster than supply, all you get is inflation.

We know from the fine print in the budget papers that Treasury’s estimate of our present potential growth rate is 2.75 per cent a year. You can be sure the Reserve’s estimate is the same. This is often referred to as the economy’s forward-looking “trend” (medium-term average) rate of growth.

Treasury’s projections of growth over the rest of the next 10 years are based on the assumption that, once the economy has returned to its trend rate of 2.75 per cent, it will then grow by 3 per cent a year for several years until the idle capacity is used up, when it will revert to 2.75 per cent. (This projection of perfection is what allows the budget papers to include an incredible graph showing the budget surplus going on forever and the government’s net public debt plunging to zero by June 2030.)

Now, here’s the trick. Because the Treasury and Reserve forecasters have no more knowledge of what the future holds than you or I do, they rely heavily on a long-established statistical regularity called “reversion to the mean”. That is, if at present the variable you’re forecasting is above its average performance, the greatest likelihood is that it will move down towards the average. If it’s below average, it’s likely to move up towards the average.

So now you know why, for at least the past eight years, Treasury has forecast that, though growth in the economy is weak at present, within a year or two it will return to trend, and then go higher. When it turns out that didn’t come to pass this time, it’s still the best bet for next year. Fail and repeat. Although the Reserve revises its forecasts every quarter, it follows the same method.

Davies’ examination of the Reserve’s forecasting record found that, since the financial crisis, it had persistently overestimated growth in real gross domestic product in the year ahead, and had nearly always overestimated growth over the next two years.

Why? Because it failed to take account of the decline in the potential growth rate since the crisis. It’s a safe bet the Reserve has stuck with 2.75 per cent. But Davies says the Reserve’s own econometric model of the economy, MARTIN, finds that potential growth has declined from 3.1 per cent in 2000 to 2.7 per cent in 2010 and 2.4 per cent in 2019.

In other words, when your forecasting method relies so heavily on reversion to the mean, if your estimate of potential growth is too high, it’s hardly surprising you’ll forecast more growth than you ever get.

But what’s wrong with the econocrats’ estimate of the potential growth? It could be in one or more of their estimates of growth in its three P components, but Davies’ checking shows it’s not population or participation, but productivity.

Davies says the MARTIN model shows that trend growth in productivity has slowed from 2 per cent a year in 2000, to 1.3 per cent in 2010 and to 1.1 per cent in 2019. This slowdown is not peculiar to Australia, but has occurred across the advanced economies.

Taking the median rate for those other economies, he estimates that the annual improvement in their productivity of labour per hour worked has slowed from 1.9 per cent in the 10 years before the crisis, to 0.8 per cent in the years since the crisis.

Davies’ equivalent estimates for us are similar: from 2.1 per cent to 1.2 per cent.

Okay, so why has productivity improvement slowed? Labour productivity has two components: “capital deepening”, where investment in more capital equipment per worker makes workers more productive, and “multi-factor productivity”, which is the improvement that can’t be explained by anything but technological progress (not more equipment so much as better equipment, plus improvements in the way factories and offices are organised) and reforms to the structure of the economy (“micro-economic reform”).

Davies finds the overall decline is mainly explained by the weakest rate of improvement in multi-factor productivity in decades – that is, little technological progress, here or overseas – but also by investment in the stock of non-mining physical capital that’s only just keeping up with the growth in the supply of labour (which, I imagine, hasn’t been helped by our need for “capital widening” to provide equipment to all the extra migrant workers).

What Davies’ digging has really exposed, of course, is the econocrats’ refusal to accept that our economy’s caught in former Bank of England governor Mervyn King’s “low-growth trap”.

How Morrison is putting politics ahead of policy

If you think Scott Morrison’s been busy doing not very much since the election in May, you are much mistaken. In truth he’s been very busy doing stuff of not much interest to you. But sometimes it pays to take an interest in things that don’t seem of interest.

For instance, I wouldn’t expect you to have taken much interest in the reshuffle of government departments he announced on Friday. But I’ve been reading up on it and been amazed – or appalled – by what I’ve learnt.

It’s said to be the most dramatic overhaul of the federal public service since 1987, cutting the number of departments from 18 to 14 while creating four new mega-departments and removing five department secretaries, three of them women.

Morrison said it was not a cost-saving measure, but had been done to “better align and bring together functions within the public service so they can all do their jobs more effectively and help more Australians”.

So be very clear on that: it’s been done to ensure you and I get better service from the public service. Specifically, the number of departments was shrunk so as to “ensure the services that Australians rely on are delivered more efficiently and effectively”.

I just have one problem: that’s what they all say. If Morrison had increased rather than decreased the number of departments, he would still have assured us it would make the public service more efficient and effective.

This is hardly the first time departmental arrangements have been changed. They’re changed after every election and often several times more. Changes are so common bureaucrats have a name for them: MoG – changes in the “machinery of government”.

According to calculations by Bob McMullan, former Labor minister turned academic, more than 200 changes have been made since 1993-94. “In 2015-16, machinery of government changes involved the movement of 8000 staff in 21 separate changes. Changes following the 2013 election, which involved the movement of 12,000 staff, cost an average of $14 million per agency.”

Governments everywhere do it, but research by academics at UNSW’s Canberra campus suggests Australian governments do it far more than others. “Even governments with an emphasis on ‘cutting red tape’ [such as this one] have undertaken extreme and costly MoG changes,” they say.

So why are the latest changes said to be the biggest since 1987? Because that’s when the Hawke government introduced the idea of merging departments into mega-departments. Paul Keating reversed some of those changes and John Howard undid much of the rest. Get it? It’s time to mega up again.

When the changes cause the name of some function to drop out of the ever-longer titles of departments, the interest group invariably sees red. A few years ago it was the scientists, this time it’s the arts. Actually, the arts have never had their own department, but have been shunted from one department to another.

Since Bob Hawke’s day they’ve gone from Environment to Communications, back to Environment, then Regional Development, Prime Minister and Cabinet, back to Regional Development, then Attorney-General’s, back to Communications and now to the new mega Department of Infrastructure, Transport, Regional Development and Communications.

So many MoG changes involve moving functions from one department to another that McMullan has christened them “merry-go-round decisions”. “Responsibility for childcare, aged care and Indigenous affairs (to name a few) have all been the subject of multiple shifts in the past decade. In some cases, the functions have moved out of one department only to return to their original home a few years later,” he says.

He adds that “disentangling financial structures, IT support structures, property responsibilities and HR systems from old organisations and reintegrating them into new ones takes considerable time and effort”.

Former boss of Prime Minister’s Terry Moran’s comment on the latest changes is blunter: “There’ll be turmoil in many departments for a significant period."

So why do the changes keep happening? Partly to create the appearance of progress – “reform”. Sometimes I think the pollies are trying to convince themselves as much as us. But mainly to indulge the preferences, prejudices and professed priorities of the prime minister and his or her ministers.

It’s notable that these extensive changes to the bureaucracy – including the sacking of five department heads – involve no changes to the ministry. The new mega Department of Agriculture, Water and the Environment will now contain three Cabinet ministers, co-equal in power and glory.

What particular preferences and prejudices of Morrison do the latest changes reveal? I think it reveals this government’s disdain for public servants. It’s the revenge of the ministerial staffers (which many ministers started their political careers as). Who needs public servants giving ministers advice when it’s the staffers who understand the politics of the matter?

This is Morrison surrounding himself with the top public servants he knows and likes, replacing the ones who want to keep talking about policy with can-do men and women who don’t argue.

Morrison has repeatedly expressed his belief that he doesn’t need policy advice from public servants. They should just be getting on with implementing the policies the government gives them.

I think this is Morrison perfecting the hermetic seal of his personal Canberra bubble. He already knows what’s on his to-do list and he doesn’t want news from the outside world delaying or deterring him from his purpose.

Please, no more Pollyanna impressions in the budget update

The mid-year budget update we’ll see next Monday presents the government and its econocrats with a threshold question: can their battered credibility withstand one more set of economic forecasts based on little more than naive optimism?

Or won’t it matter if first the industry experts, and then the Quiet Australians in voterland, get the message that budgets are largely works of fiction - based on political spin, with forecasts crafted to fit - and so are not to be believed?

Last week’s national accounts confirmed five successive quarters of weak growth in the economy and left Reserve Bank governor Dr Philip Lowe’s lovely thought of the economy reaching a “gentle turning-point” looking pretty ragged.

Maybe if you squint you could see a pattern of improvement, with the economy’s weakness concentrated in the last two quarters of 2018 (growth in real GDP of 0.3 per cent and 0.2 per cent), and strength returning in the first three quarters of this year: 0.5 per cent, 0.6 per cent and now 0.4 per cent.

Trouble is, that ain’t economics, it’s numerology: looking at a pattern of numbers without troubling your head with the varying factors that are driving them. Look at what’s driving those numbers and the illusion is dispelled.

Every part of the private sector is weak: consumer spending, home building and business investment, so much so that, as a whole, it’s actually contracting. That consumer spending is weak and getting weaker – despite the tax cut and three cuts in interest rates – is hardly surprising when you remember how weak the growth in wages has been.

It’s a great thing that public sector spending is providing most of what little growth we’re getting while the private sector goes backwards, but it doesn’t count as a sign the economy’s getting back on its feet.

As for the contribution from net exports, it would be more encouraging if it weren’t for the knowledge that a fair bit of it comes from the fall in imports you’d expect to see when domestic demand is “flat to down”.

But for a disillusioning summary statistic, try this: real household disposable income per person – a good measure of average material living standards - has essentially been flat since the end of 2011. So the Quiet Australians have nothing to show for eight years of toil. The rest is a conjuring trick where high population growth is passed off as growing prosperity.

Three quarters into our run of five weak quarters, Scott Morrison fought the election on a claim to have delivered a Strong Economy. The two subsequent sets of national accounts have destroyed that masterpiece of the marketer’s art.

But Morrison’s misrepresentations came bolstered by Treasury forecasts and projections showing the economy would quickly recover from weakness to strength, whereupon it would enter a five-year period of above-trend (3 per cent) annual growth before reverting to trend for the rest of a decade.

This flight of back-of-an-envelope fancy not only appeared to be Treasury’s endorsement of Morrison’s unfounded claims about strong growth, they supported the government’s claim that the budget could easily afford to double the tax cuts announced in the previous year’s budget – taking the cumulative cost to revenue to $300 billion over a decade – and still achieve healthy annual surpluses, eliminating the government’s net public debt by June 2030.

Just eight months later, these fearless forecasts aren’t looking too flash. They had the economy returning to trend growth of 2.75 per cent this financial year and inflation returning to 2.5 per cent by June 2021.

Most wonderful of all, they had annual wage growth accelerating to 2.5 per cent by June (actual: 2.3 per cent, falling to 2.2 per cent following quarter), to 2.75 per cent by June next year, then to 3.25 per cent by June 2021 and 3.5 per cent by June 2022 and in all subsequent years.

Wages are such a central driver of the economy, this triumph of hope over experience was essential to any forecast recovery in consumer spending and economic growth, not to mention any return to (bracket-creep-fuelled) budget surpluses despite tax cuts.

See the problem Treasurer Josh Frydenberg and his troops face in preparing next Monday’s mid-year budget update? Do they keep playing the budgetary version of the with-one-bound-our-hero-broke-free game and leave themselves open to growing derision, or do they stop pretending, offer plausible forecasts and adopt a more defensible projection methodology, and start on the long road back to being respected and authoritative?

But if the days of Treasury being game to give the boss (Morrison) forecasts he won’t like are long gone, that raises a courage question for the Reserve heavies: when will they stop ensuring their forecasts tick-tack with Treasury’s and start telling us what they really think?
