THE GLOBAL ECONOMY

Aurora College Economics HSC Study Day, Sydney

Every year there’s some event in the news that’s relevant to your study of the global economy, and this year it’s the growing realisation that the process of globalisation has stopped and begun to reverse – “deglobalisation”. The pandemic hasn’t helped, nor has the invasion of Ukraine, but it’s the increasing tension between the US and China that has raised the spectre of the world being divided into two rival trading blocs. It’s likely the value of world trade will fall in 2023.

The arrival of the pandemic in early 2020 led to an immediate fall in world trade, but it recovered sharply the following year. However, the disruption to the supply of many imported goods has led some countries and companies to “re-shore” their supply chains, by producing more goods and components at home rather than abroad. While making their supply more reliable, this will raise the cost of those products. For some, this has just been the latest excuse for protection against competition from imports. The IMF has argued that supply chains can be diversified – made reliant on a wider range of foreign suppliers – without losing the benefits from trade.

The invasion of Ukraine has disrupted the supply of oil and gas from Russia to many European economies, as well as the supply of wheat and other foodstuffs to developing countries. This has happened not so much because of the war as because of the trade sanctions imposed on Russia by the US and its many allies. As the war drags on, the Europeans and others move to alternative suppliers, a process known as “friend-shoring” – moving your trade to countries you get on with, not necessarily those offering the best prices or service.

America’s swing to protectionism

For many decades, the US was the great champion of free trade and rules-based trading under the GATT – the General Agreement on Tariffs and Trade – and its successor, the World Trade Organisation. It was the support of the US that allowed China to become a member of the WTO in 2001, leading to huge growth in international trade and globalisation. Much manufacturing activity moved to China from the developed economies, leading to decades of lower prices for manufactured goods throughout the world, and the accelerated growth of the Chinese economy. But it also led to much unemployment for displaced factory workers in the US. While all consumers benefited from the cheaper imports, far too little was done to help those workers find employment elsewhere. This was the grass-roots cause of America’s swing to protectionism.

President Donald Trump won election in 2016 on a promise of protecting American industry against “unfair” competition from developing countries and, in particular, China. He launched a trade war with China, made changes to various trade agreements, and refused to join a US-sponsored trade agreement with Japan, Australia and various other Asian economies (which went ahead anyway). What’s now apparent is that US protectionism, and the trade war with China, have continued under President Joe Biden. He has resorted to subsidies and export controls, contrary to WTO rules.

It's now clear the US is motivated not just by protectionism, but also big-power rivalry with China. America is unwilling to share power with the rising superpower, China. It is particularly unwilling to have China overtake it as leader in advances in digital technology. When politicians and officials say they are worried about the effect of “geostrategic conflict” on world trade, this is what they mean. When they worry about the “fragmentation” of world trade, they mean they fear the world could divide into two rival trading blocs, led by America and China. This would involve great losses of the “gains from trade” through pursuit of “comparative advantage”. In October 2022, the US imposed sweeping restrictions on exports of semiconductors (chips), aimed at preventing China from advancing technologically. This also explains America’s efforts to stop Huawei and TikTok from expanding outside China.

Definition

The OECD defines globalisation as “the economic integration of different countries through growing freedom of movement across national borders of goods, services, capital, ideas and people”.

That’s a good definition, but I like my own: globalisation is the process by which the natural and government-created barriers between national economies are broken down.

Globalisation’s two driving forces

With this definition I’m trying to make a few points. One is that globalisation has had two quite different driving forces. The one we hear most about is the decisions of governments around the world to break down the barriers they have created to limit flows of goods and money between countries by reducing their protection of domestic industries and by deregulating their financial markets and floating their currencies.

But the second factor promoting globalisation is just as important, if not more so: advances in technology – including advances in telecommunications, digitisation and the internet, which have hugely reduced the cost of moving information and news around the world, as well as increasing the speed of its movement. This has allowed a huge increase in trade in digitised services. As well, advances in shipping – containerisation, bigger and more fuel-efficient ships – and in air transport have led to increased movement of goods and people between countries.  

Globalisation is a process

Another point my definition makes is that globalisation is a process, not a set state of being. Because it’s a process, it can go forward – the world can become more globalised – or it can go backwards, as national governments, under pressure from their electorates, seek to stop or even reverse the process of economic integration. Among the advocates of globalisation there tended to be an assumption that the process of ever greater integration was inevitable and inexorable. That was always a mistaken notion.

Earlier globalisation

The process of globalisation is and always was reversible. People should know this because this isn’t the first time the process of globalisation has occurred and then been rolled back. The decades leading up to World War I saw reduced barriers and greatly increased flows of goods, funds and people between the old world of Europe and the new world of America, Australia and other countries. But this integration was brought to a halt in 1914 by the onset of a world war. And the period of beggar-thy-neighbour increases in trade protection, to which countries resorted in response to the Great Depression of the early 1930s, greatly increased the barriers between national economies. Indeed, in the years after World War II, the many rounds of multilateral tariff reductions brought about under the GATT – the General Agreement on Tariffs and Trade, which has since become the World Trade Organisation – were intended to dismantle all the barriers to trade built up in the period between the wars.

The era of hyperglobalisation

The period between the end of World War II in 1945 and the late 1980s saw huge growth in trade between the advanced economies, as a consequence of those successive rounds of tariff reductions. But from the late ’80s until the global financial crisis and Great Recession of 2008 there was a period of “hyperglobalisation” in which trade between the developed and developing countries grew hugely. This was partly because of the way the digital revolution and other technological change broke down the natural barriers between countries. But also the result of the eighth and final “Uruguay round” of the GATT in 1994 reducing tariff and other trade barriers between the developed and developing countries.  Many poor countries joined the new WTO at this time, with China joining in 2001.

One measure of the extent of globalisation is the growth in two-way trade between countries (exports plus imports) as a proportion of gross world product (world GDP). Between 1990 and 2008, global trade rose from 39 pc to 61 pc of GWP – the period of rapid globalisation.

Note that the poor countries did well out of the quarter-century of rapid globalisation. Between 1995 and 2019, real GDP per person in the emerging economies more than doubled, whereas in the advanced economies it grew by only 44 pc (after allowing for differences in purchasing power).

The era of deglobalisation

But the end of hyperglobalisation can be dated to the global financial crisis in 2008, and the new era of “deglobalisation” has continued during the pandemic. Two-way trade as a proportion GWP fell after the global financial crisis, and even by 2019 had not regained its peak in 2008.

Among the signs of deglobalisation are Britain’s vote in 2016 to leave the European Union – Brexit – and thus to reduce its degree of economic integration with the rest of Europe – a decision most outsiders see as involving a significant economic cost to the Brits’ economy. Second, the Trump administration withdrew from the Trans Pacific Partnership, an agreement between the US and 11 other selected countries (including Australia) to reduce barriers to trade between them – although the remaining 11 finalised an agreement without the US.  Third, the Trump administration withdrew from the Paris global agreement on reducing greenhouse gas emissions. Fourth, Trump launched a trade war with China. President Biden has re-joined the Paris agreement and repaired America’s relations with its allies, but continues the contest with China.

The temptation of returning to protectionism

The period of hyperglobalisation saw the shift of much manufacturing from the rich countries (including Australia) to China and other developing countries with cheaper labour. But it’s likely that, in the period of slower growth that followed the global financial crisis, some countries yielded to the temptation to return to protecting their domestic industries against foreign competition, returning to the (failed) strategy of growth through “import replacement” rather than “export-led” growth. Regrettably, this trend is being led by the two biggest developing economies, China and India. China raised its import barriers against many Australian exports, but is now lowering them.

This trend has continued during the pandemic, with The Economist magazine reporting that countries have passed more than 140 special trade restrictions during the pandemic. Some of these may arise from concerns in the rich countries during the pandemic over the lack of availability of personal protective equipment, or vaccines. Worries about the pandemic’s disruption of global supply chains may be another reason for the return of protectionist attitudes in the advanced economies.

The channels of globalisation

The four main economic channels through which the world’s economies have become more integrated are:

1) Trade in goods and services

2) Finance and investment

3) Labour

4) Information, news and ideas.

Trade is probably the channel that gets most attention from the public. Donald Trump’s populist campaigning against globalisation focused on the belief that America’s greater openness to trade – particularly with developing countries – caused it to lose many jobs, particularly in manufacturing, as cheaper imports caused many domestic producers to lose sales, or as factories have been moved offshore to countries where wages are lower, without America receiving anything much in return.

Surprisingly, financial globalisation didn’t get as much blame as it could have for the global financial crisis and the Great Recession it precipitated. Most countries have not liberalised the flow of labour into their economy in the way they have the other factors of production.

Income distribution and the gains from trade

One of economists’ core beliefs is that there are mutual gains from trade. Provided the exchange of goods is voluntary, each side participates only because it sees some advantage for itself. This is undoubtedly true, but in the era of renewed globalisation we’ve been reminded that, though the gains may be mutual, they are not necessarily equal. Some countries do better than others.

Similarly, the benefits to a particular country from its trade aren’t necessarily equally distributed between the people within that country. When, for example, a country imports more of its manufactured goods because they are cheaper than its locally made goods, all the consumers who buy those goods are better off (including all the working people), but many workers in the domestic manufacturing industry may lose their jobs.

Another factor that has been working in the same direction is digitisation and other technological change which, in its effect on employers’ demand for labour, seems to be “skill-biased” – that is, it tends to increase the value of highly skilled labour, while reducing the value of less-skilled labour. It seems likely that, between them, trade and technological advance have worked to shift the distribution of income in America, Britain and, to a lesser extent, Australia, in favour of high-income families and against many middle and lower-income families.

The unwelcome surprise many politicians and economists have received from the high protest votes for Brexit, Trump and One Nation is causing them to wonder if too little has been done to assist the workers and regions adversely affected to retrain and relocate, and too little to ensure the winners from structural change bear most of the cost of this assistance.

Grim Reaper is catching up with the Baby Boomers, waving bills

Having witnessed the last days of my parents and in-laws, I don’t delude myself – as they did – that I’ll be able to avoid being carted off to an old people’s home. Sorry, an aged care residential facility.

Actually, I dream of dying in the saddle. My last, half-finished column would be the announcement that I’d finally made way for the bright young women coming up behind me. That’s assuming they hadn’t already found a chance to push me under a bus.

Speaking of bright young women, Anthony Albanese’s Minister for Aged Care and Sport, Anika Wells, seems to be attacking her job with much more enthusiasm than her Coalition predecessors.

In a speech to the National Press Club last week, she noted that Labor inherited a system that a royal commission had characterised with a single word – “neglect”. She’d spent the past 12 months engaged in “triage” and “urgent reform” and was now able to think about the future.

And what’s she been thinking? “I don’t want Australians to be scared about the care they will be provided in later life,” she said. “I don’t want daughters and sons worried about the treatment their parents will receive.”

The Howard government’s Aged Care Act of 1997 was aimed at saving money by turning aged care over to community and for-profit providers. It was focused on how the providers were to run their services, setting out their obligations and responsibilities.

But, as recommended by the royal commission, the government planned to introduce a new act next year, this time focused on the rights of older people, with “a clear statement that the care provided to residents is safe and of high quality”.

Labor had already done much to fix the system, she said, but there were more challenges ahead, and “we must act now”. Why? Because “the Baby Boomers are coming”. (I’d have thought they’d come some time ago, and the real problem was their looming departure.)

But I imagine the Boomers (present company excepted) will be living a lot longer than previous generations – thanks to advances in medical science and being the first generation to realise that exercise was something to be sought and enjoyed, not avoided.

But though their arrival in aged care may be at a later age, their later lives won’t be trouble-free and certainly not doctor-free.

One change we’ll be seeing is more in-home care. Almost everyone would prefer to keep living at home rather than go off to a “facility” (sounds like a toilet block). The previous government did introduce the home-care package, but it was expensive and so was limited in how many people were given it.

Wells is introducing a new Support at Home program in July 2025 which, by delaying or eliminating people’s move to facility care, should save money.

But her big announcement last week was the setting up of an aged care taskforce – chaired by her good self – to answer the royal commission’s “great unanswered question”: How to make aged care equitable and sustainable into the future?

Which is a politician’s way of saying, “How we gonna pay for all this?”

One of the commissioners wanted a new aged care tax levy of 1 per cent of everyone’s taxable income (which, in practice, would be added to the present 2 per cent Medicare levy), whereas the other wanted some unspecified combination of a levy and a means-tested contribution from users.

Wells notes that, within a decade, we’ll have, for the first time ever, more people aged over 65 than under 18. And the proportion of people aged 15 to 64 – the people working and paying income tax – will shrink.

Now, this is the point where we need to remember that we’ve gone for decades stacking the financial rules against the younger generation and in favour of the oldies. We’ve kept handing tax breaks to the ageing. Old people can have good incomes that are largely untaxed, whereas young people on the same money have to pay up - and pay for their tertiary education.

It’s not true that every Boomer’s rolling in it – there are poor people in every generation – but most have done pretty well. Most were able to climb aboard the home-ownership gravy train when homes were still affordable. Many have been able to buy an investment property or two on the top.

And though the compulsory superannuation scheme hasn’t applied to the whole of their working lives, they’ll be retiring with a lot more, hugely taxpayer-subsidised super than any previous generation.

So, the idea of spreading the entire cost of the Boomers’ aged care – whether in-home or in-facility – across all those people young enough to still be working and paying income tax ought to be unthinkable.

If Labor doesn’t summon the courage to ask those Baby Boomers who’ve done OK to help pay directly for the cost of their highly privileged lives’ last stage, it will just prove what a rotten world Albo and the rest of us have left our offspring.

Economy close to stalling, as Reserve hits the brakes yet again

It’s been a puzzling week, as we learnt the economy had slowed almost to stalling speed, just a day after the Reserve Bank raised interest rates for the 12th time, and warned there may be more.

According to the Australian Bureau of Statistics’ “national accounts”, real gross domestic product – the economy’s production of goods and services – grew by just 0.2 per cent over the three months to the end of March.

That took growth over the year to March down to 2.3 per cent, which sounds better than it is because the economy has slowed so rapidly. If it continued growing by 0.2 per cent a quarter, that would be annual growth of 0.8 per cent.

And the resumption of immigration means the population is now growing faster than the economy. Allow for population growth and GDP per person actually fell by 0.2 per cent. Over the year to March, it grew by only 0.3 per cent.

While a growing population is good for businesses – they have more potential customers – to everyone else, economic growth has been sold to us as raising our material standard of living. Not much chance of that if GDP per person is falling.

The Reserve Bank has been trying to slow the economy down because demand for goods and services has been growing faster than the economy’s ability to supply them, thus allowing businesses to increase their prices.

With additional help from the rising prices of imported goods and services, the rate of inflation has shot up. It’s started falling back from its peak of 7.8 per cent at the end of last year, but is still way above the Reserve’s 2 per cent to 3 per cent target range.

The Reserve’s been raising the interest rates paid by the third of households with mortgages, to reduce their ability to spend on other things. But, at this stage, probably the biggest dampener on consumer spending is coming from the failure of wages to keep up with rising prices.

“Demand” means spending, so if households find it harder to spend on goods and services, that makes it harder for businesses to raise their prices, thus bringing the inflation rate back down.

And remember that the full effect of all the interest rate rises we’ve seen is still to be felt. The pain will increase over the rest of this year.

But if I were Reserve Bank governor Dr Philip Lowe, I wouldn’t be too worried that the plan wasn’t working. The biggest single factor driving GDP is consumer spending, which accounts for more than half of all spending. In the June quarter last year, it grew by 2.2 per cent.

The following quarter its growth fell to 0.8 per cent, then 0.3 per cent, and now 0.2 per cent. Wow. I think the squeeze is working.

Although more people have been working more hours, real household disposable income fell by 0.3 per cent in the quarter, and by 4 per cent over the year to March.

It was hit by the failure of wages to rise in line with prices, by the doubling in households’ interest payments, and by the bigger bite that income tax took out of pay rises, caused by bracket creep.

How did households manage to keep their consumption spending growing despite their falling real income? By cutting the proportion of their income that they were saving from more than 11 per cent in March quarter last year to less than 4 per cent this March quarter – the lowest it’s been in about 15 years.

Household investment spending on newly built homes and alterations fell by 1.2 per cent, its sixth fall in seven quarters.

One bright spot was growth in business spending during the quarter of 2.9 per cent, led by spending on machinery and equipment, and non-dwelling construction – particularly on renewables and electricity infrastructure.

Unfortunately, much of the machinery investment was on imported equipment that had been delayed by the pandemic, so it’s not a sign of continuing strength. The volume of spending on imports was a super-strong 3.2 per cent, but imports subtract from GDP, of course.

Treasurer Jim Chalmers always blames the economy’s slowdown on higher interest rates (blame the Reserve, not me), high inflation (not me either) and “a slowing global economy” (blame the rest of the world).

A slowing global economy? Yes, of course. Everyone’s heard about that. Trouble is, the main way the rest of the world affects us is by buying – or not buying – our exports. And the volume of our exports grew by 1.8 per cent in the March quarter, and 10.8 per cent over the year to March. That’s because our miners have done so well (and our fossil-fuel-using households and businesses so badly) out of the higher world coal and gas prices caused by the Ukraine war.

Even so, this quarter’s growth in export volumes of 1.8 per cent has been swamped by the 3.2 per cent growth in import volumes, meaning that “net exports” – exports minus imports – subtracted 0.2 percentage points from the overall growth in real GDP during the quarter.

After Lowe’s decision on Tuesday to raise rates yet again, Chalmers wasn’t mincing his words. “I do expect that there will be a lot of Australians who find this decision difficult to understand and difficult to cop – ordinary working Australians are already bearing the brunt of these interest rate rises, they shouldn’t bear the blame too,” he said.

“The Reserve Bank’s job is to quash inflation without crashing the economy, and they will have a lot of time and opportunities to explain and defend the decision that they’ve taken today.”

Lowe has said repeatedly that he’s seeking the “narrow path” where “inflation returns to target within a reasonable timeframe, while the economy continues to grow, and we hold on to as many of the gains in the labour market [our return to full employment] as we can”.

After seeing the next day’s GDP figures, Paul Bloxham of HSBC bank observed that the narrow path “is looking extremely narrow indeed”. True.

Consumerism and social status keep our noses to the grindstone

What better time to think about whether we’re working too hard than while we’re enjoying a Monday off, thanks to a public holiday? Wouldn’t it be nice if every weekend could be a long weekend?

Actually, almost 100 years ago, the greatest economist of the 20th century, John Maynard Keynes, pretty much predicted that’s the way we’d be living by now.

In his essay Economic Possibilities for our Grandchildren, written in 1930, he envisaged that by now, we’d be able to live comfortably while having to work only 15 hours a week. We could work just three hours each weekday, or clock up our 15 hours in just a few days – say, three five-hour days.

Really? What a duffer. How could anyone so smart be so disastrously wrong?

Well, not quite. What Keynes was saying was that, technological advance – the invention of ever-better labour-saving machines – would increase the productivity of our labour to such an extent that, by now, we wouldn’t need to work very hard to be able to live comfortably.

His point was that, as we’re able to produce more goods and services per hour of work, we become better off. We can take that benefit either as enjoying an unchanged material standard of living while working fewer hours a week, or as higher monetary income – thus allowing us to buy more stuff – while working the same number of hours.

As Jan Behringer and other economists from Germany’s University of Duisburg-Essen have written, in the years since Keynes made that prediction the productivity of labour in the developed economies has improved by more than he expected.

So, we could have been working a 15-hour week had we chosen to but, in fact, we chose to take the money and the extra stuff rather than the extra leisure. Working hours have fallen since the 1930s, but not by all that much.

Behringer and colleagues say the “obstacles to more leisure time are primarily sociopolitical in nature” – by which they mean it’s not purely economic reasons, the shortage of resources, that require us to work more.

I’ve no doubt it has suited the rich and powerful to have us working and spending rather than devoting four days a week to developing our hobbies. That way, the rich and powerful get more so.

But, by the same token, I think the rest of us have been easily seduced by the lure of the materialist, consumer culture. We love buying things that are new, shinier and do better tricks.

In Australia – and in Europe, but less so in America – pretty much all the reductions in working hours, the increases in annual leave and sick leave, and the introduction of that strange animal, long service leave, have happened because union-backed governments have imposed them on unwilling employers.

And every time they have, the employers and their political parties have predicted the death and destruction of the economy.

But, even so, how long since you’ve seen a union telling its bosses they should go easy on the pay rise, but cut working hours? No, I have no doubt that the workers have preferred more bangles and baubles.

Behringer and colleagues, however, have a different take. Their study of developments in the US and Europe over the decades leads them to two conclusions.

First, since the 1980s, average working hours have fallen more slowly as inequality – the gap between high and low incomes – has increased.

Second, in countries with high inequality, employees earning higher hourly wage rates tend to work longer hours than those on lower hourly wage rates.

Both these findings are striking because they contradict economists’ earlier finding that people with higher incomes chose to increase their leisure time.

So, what’s going on? The authors’ explanation is that rising inequality of incomes leads to more “upward status comparisons”. Like most social animals, we are conscious of our social status – where we fit in the pecking order.

And, particularly where there’s a big difference between the top and the bottom, we seek to improve our position.

“The upper middle class emulates the consumption norms of the rich, and sacrifices leisure time to do so. Because the rich also increase their spending on status goods such as housing, education, etc as their incomes rise, the middle class feels pressure to keep up,” they say.

“After all, what constitutes ‘a good place to live’ or ‘a good education’ is essentially defined in comparison to the standards that the upper income groups largely determine.”

Another of their findings is that working hours are more likely to be shorter when wage bargaining is centralised and government social benefits in kind (but not in cash) are more adequate.

One possible explanation, they say, is that centralised wage bargaining reduces status conflict because workers can decide collectively to avoid a “positional arms race” to allow shorter working hours and more leisure.

They find that social benefits in kind rather than cash are associated with lower hours of work. This may be because the direct provision of goods and services by governments reduces the need for status-oriented private spending on goods and services.

Education has many dimensions. It broadens the mind, it helps you get a better-paying job, and it’s a “positional good” – it helps people judge your social status.

"The extent to which the education sector is organised through private markets is found to be associated with longer working hours among workers who themselves have high levels of education,” the authors say.

Get it? If governments provided better healthcare and public schools, more people would be content to use the publicly provided services along with everyone else, and fewer people would feel the need to work longer to afford private hospitals and schools.

It's not the wolf at the door that's driving women to work harder

Why do mothers go out to work? Why are more women doing paid work than ever before? And why are more of those women working full-time? At a time when so many are struggling with the cost of living, it’s easy to conclude that more women are having to work more hours just to keep up. But I think that sells women short.

Worse, it’s a fundamental misreading of perhaps the greatest social change of our age: the economic emancipation of women.

I don’t doubt that women are just as concerned about the cost of living as men, maybe more so if they’re in charge of the family budget. Nor do I doubt that, if you ask a woman why she’s been doing more paid work lately, the cost of living’s likely to be mentioned.

But things are not always as they seem. For instance, when people complain about the cost of living, their focus is on rising prices. But prices rise almost continuously. What matters more is whether wages are rising as fast as prices are – or, preferably, a little faster.

It’s true that the prices for goods and services have risen at a much faster rate than normal over the past two years or so. But the real problem is that wages – which usually do keep up – have been falling behind since the start of the pandemic. Yet people are far more conscious of the rising prices than of the weak wage growth.

Another distinction that’s clearer to economists than to normal people is between the cost of living and the standard of living. When people have trouble maintaining the same standard of living as their friends – a comparable car, comparable house, comparable private school – they would often rather blame the cost of living than their need to keep up with the Joneses.

No, what’s driving the change in women’s lives – causing them to behave very differently from their grandmothers – isn’t the cost of living, it’s education. And with education has come aspiration. Aspiration to put their learning to work, to have a career as well as a family, and to be treated equally with men.

I think it all started sometime in the 1960s when, for some unknown reason, the parents of the rich world accepted that their daughters were just as entitled to a good education as their sons. Everything flows from that fateful change in social attitudes and behaviour. What father today would dream of telling his daughter that, being a girl, she didn’t need an education?

The trouble for boys is that girls do education better. It’s now several decades since the number of girls going to university first exceeded the number of boys.

That being so, the figures for two-income families should come as little surprise. The latest report from the federal government’s Australian Institute of Family Studies, Employment patterns and trends for families with children, finds that in 2022, both parents were employed in 71 per cent of couple families with children under 15. This is up from 56 per cent in 2000, and 40 per cent in 1979.

Within those couple families, the proportion with both parents working full-time was 31 per cent in 2021, up from 22 per cent 12 years earlier. The proportion with one parent working full-time and the other part-time is unchanged at 36 per cent.

Only 4 per cent of these families involved fathers who weren’t working and mothers who were. (Which leaves the young men in my immediate family looking good.)

But there’s something else you need to understand. In the days when there weren’t many two-income families, this gave them a distinct advantage in the housing market. They could afford a better house than their peers.

Once most young home-buying couples have two incomes, however, their greater purchasing power gets built into the prices of the kind of houses they buy, so that what began as an advantage turns into a requirement.

Now it’s the couples who choose not to have both partners working who’ll have trouble affording a home comparable to those of other couples. They’ll have to accept a lower standard of living.

Similarly, it’s a misconception to say, as some do, that you need to have both parents working to afford a family. No, you just have to accept a lower standard of living.

I’ve long suspected that the rise of the two-income family helps explain the growing practice of sending kids to private schools. Two incomes make this easier to afford – though this, too, gets built into the size of the fees the schools can get away with charging.

There’s no reason a mother – or a father – who chooses to have a career should feel guilty about it. But I suspect some double-income couples find it easier to justify if they can say that the extra money is buying their kids a better education.

Sorry, a mountain of evidence says that, once you allow for the parents’ socio-economic status, private schools don’t add to students’ academic performance. Buyer beware.

Business cries poor on wages, even as profits mount

Don’t believe anyone – not even a governor of the Reserve Bank – trying to tell you the Fair Work Commission’s decision to increase minimum award wages by 5.75 per cent is anything other than good news for the lowest-paid quarter of wage earners.

Because they are so low paid, and mainly part-time, these people account for only about 11 per cent of the nation’s total wage bill. So, as the commission says, the pay rise “will make only a modest contribution to total wages growth in 2023-24 and will consequently not cause or contribute to any wage-spiral”.

But that’s not the impression you’d get from all the wailing and gnashing of teeth by the main employer group, the Australian Chamber of Commerce and Industry. It claims “an arbitrary increase of this magnitude consigns Australia to high inflation, mounting interest rates and fewer jobs”.

These are the sort of dramatics we get from the Canberra-based employers’ lobby before and after every annual wage review. They lay it on so thick I doubt anyone much believes them.

But it’s worse than that. In the age-old struggle between labour and capital – wages and profits – most economists have decided long ago whose side they’re on, and long ago lost sight of how one-eyed they’ve become.

For a start, many of the talking heads you see on telly work for big businesses. They’re never going to be caught saying nice things about pay rises.

Econocrats working for conservative governments have to watch what they say. And parts of the media have business plans that say: pick a lucrative market segment, then tell ’em what they want to hear.

In my experience, there’s never any shortage of experts willing to fly to the defence of the rich and powerful, in the hope that some of the money comes their way.

But I confess to being shocked in recent times by the way the present Reserve Bank governor, Dr Philip Lowe, has been so willing to take sides. The way he preaches restraint to ordinary workers struggling to cope with the cost of living, but never urges businesses to show restraint in the enthusiasm with which they’ve been whacking up their prices.

It’s true that Lowe has a board that’s been stacked with business people, but that’s been true for all his predecessors, and they were never so openly partisan.

When businesses take advantage of the excessively strong demand that Lowe himself helped to create, that’s just business doing what comes naturally, and must never be questioned, even in an economy characterised by so much oligopoly – big companies with the power to influence the prices they charge.

But when employees unite to demand pay rises at least sufficient to cover the rising cost of living, this is quite illegitimate and to be condemned. The more so when a government agency such as the Fair Work Commission acts to protect the incomes of the poorest workers.

On Friday, the commission set out what has long been the rule for fair and efficient division of the spoils of the market system between labour and capital: “In the medium to long term, it is desirable that modern award minimum wages maintain their real value and increase in line with the trend rate of national productivity growth”.

In other words, wage rises don’t add to inflation unless their growth exceeding inflation exceeds the nationwide (not the particular business’) trend (that is, over a run of years, not just the last couple) rate of growth in the productivity of labour (production per hour worked).

But last week, in his appearance before a Senate committee, Lowe was twisting the rule to suit his case, setting nominal (before taking account of inflation) unit labour costs (labour costs adjusted for productivity improvement) not real unit labour costs as the appropriate measure.

He told the senators that growth in labour costs per unit of 3 or 4 per cent a year was adding to inflation because the past few years had seen no growth in the productivity of labour (which, of course, is the fault of the government, not the businesses doing the production).

This is dishonest. What he was implying was that wage growth should not bear any relationship to what’s happening to prices at the time. Wage growth should be capped at 2.5 per cent a year every year, come hell or high water.

Without any productivity improvement, any wage growth exceeding 2.5 per cent was inflationary. Should the nation’s businesses choose to raise their prices by more than 2.5 per cent, what was best for the economy was for the workers’ wages to fall in real terms.

Now, Lowe is a very smart man, and I’m sure he doesn’t actually believe anything so silly. Like the employer groups, he’s cooked up a convenient argument to help him achieve his KPIs. He sees the inflation rate as his key performance indicator.

He’s got to get it down to the 2 to 3 per cent target range, and get it down quick. He ain’t too worried what shortcuts he takes or who gets hurt in the process.

When he claims that, absent productivity improvement, wage rises far lower than the rate of inflation are themselves inflationary, what he really means is that they make it harder for him to achieve his KPIs.

Clearly, the wage rise that would help him get the inflation rate down fastest is a wage rise of zero. It would plunge the economy into recession, and businesses would have a lot more trouble finding customers, but who cares about that?

It’s not true that sub-inflation-rate pay rises add to inflation. What is true is that the bigger the sub-inflation rise, the longer it takes to get inflation down. But he doesn’t like to say that.

Why’s he in such a hurry he’s happy for ordinary workers to suffer? Because he lies awake at night worrying that, if it takes too long to get inflation down, inflation expectations will rise and a price-wage spiral will become entrenched.

Does Treasury secretary Dr Steven Kennedy also lie awake? Doesn’t seem to. He told the senators last week that “there are no signs of a wage-price spiral developing and medium-term inflation expectations remain well anchored”.

If ever there was a general fighting the last war, it’s Lowe.

Meanwhile, please don’t say business profits seem to be going fine. It may be true, but please don’t say it. Business doesn’t like you saying such offensive things, and business’ media cheer squad goes ape.

For better housing affordability, try the premier, not the PM

People have been complaining about the unaffordability of houses for as long as I’ve been a journalist. In all that time, governments have professed great concern, while doing nothing of consequence. But I suspect their insouciance can’t last much longer.

Over the years, the prices of houses and apartments have risen much faster that household incomes have risen, gradually lowering the proportion of Australians able to afford a home of their own.

So the problem keeps getting worse and, with interest rates having risen so far so fast, as well as renters now feeling so much pain, it wouldn’t surprise me if, in coming federal and state elections, many younger voters – and some of their parents – were really steamed up about the issue.

If so, both Labor and the Liberals will be vulnerable to minor parties offering solutions – sensible or otherwise. But what could the major parties do to reduce the problem?

Well, nothing that some people wouldn’t vigorously object to. That’s why the political duopoly has done so little for so long.

The unending rise in house prices has been caused by various factors – some under the control of the federal government, some controlled by the states.

If prices keep rising, this suggests that demand is outstripping supply. In general, the feds have more direct influence over the demand for housing, whereas the states have more direct influence over the supply of them.

It’s wrong to assume that all the problems are coming from either the demand side or the supply side. But, of late, economists have been focusing on the supply side, which points the finger at state governments.

At first blush, if house prices are high and rising, this suggests not enough houses are being built. That’s probably true at present, with immigrants coming faster than we’re building new dwellings for them to live in.

But, over the decades, supply has eventually caught up with demand, so that doesn’t explain why prices have been rising for ages.

And, if it was just a matter of building enough houses to accommodate the growing population, cities would just keep spreading out for ever. That would be expensive – with all the extra transport and infrastructure you’d have to build – and not everyone wants to live that far out from the CBD.

So, the real supply issue is not that we should be building enough houses, it’s building enough housing where people want to live. And the truth is that many people want to live closer in.

As the NSW Productivity Commission explains in a new report, state planning systems make it “difficult to build enough new homes where people want to live – close to jobs, transport, schools and other amenities”.

“Instead, the system encourages urban sprawl, forcing people into longer and longer commutes. These policies increase inequality, especially for low and middle-income workers.”

Guess what happens if governments don’t allow enough homes to be built where people want to live? The prices of homes in, or nearer to, the most desirable areas get bid up relative to prices out in the boondocks, forcing up the median price.

As Australia’s population has grown so rapidly over the decades, the populations of Sydney, Melbourne and the other state capitals have increased greatly, but done so mainly by spreading out.

This has made housing more expensive, as people have had to pay more to live in the closer-in, more desirable parts of the city. Inevitably, it’s the better-off who get the best spots and the less well-paid who have to live further out, where the amenity is less.

Everyone’s paying more for their housing, but the well-off pay a smaller proportion of their income than those in the middle and at the bottom. This pushes families to compromise on where they live – further from family, friends and jobs.

The NSW Productivity Commission report says poor housing affordability brings four disadvantages to individual families and the community. It leaves families with less to spend on other things. It reduces the productivity of the nation’s labour because so many people who want to work can’t afford to live near their best employment prospects.

It adds to environmental damage because more workers live further from city centres and endure long, polluting commutes to their jobs.

And it reduces people’s quality of life because so much of our cities’ populations end up too far from the beach, sports arenas, big entertainment venues and other amenities.

So, what can state governments do to reduce these costs and make our lives better?

We should build more new homes in areas closer to the city’s centre. “These areas offer both the richest collection of job opportunities, and a supply of already-built infrastructure and other amenities whose capacity can be leveraged and expanded,” the report says.

What we need to do is build up, not out, and achieve more “infill” of unused or underutilised land close in.

Specifically, the report says, we need three changes. First, raise average apartment heights in suburbs close to the CBD (and to job opportunities).

Second, allow more development around transport hubs, such as train stations, and take advantage of our existing infrastructure capacity.

And third, encourage more townhouses and other medium-density development, and allow more dual-occupancy uses such as granny flats, where higher density is not an option.

The report argues that, even if the new supply of homes targets the high end of town, building more housing closer to the CBD, “downward filtering” means affordability improves everywhere.

The new, more expensive homes near the centre will be occupied by high-income families. But they will leave behind high-quality homes that middle-income families can move to, leaving their homes to be occupied by lower-income families.

NSW Productivity Commissioner Peter Achterstraat says that “if you believe, as I do, that today’s kids deserve the same shot at the Australian dream that my generation had, we need to change our planning system and build near existing infrastructure to make room for them”.
