The last thing we need: neutering the free-trade referee

With the coronavirus putting the world economy into its worst dive in almost a century, it would help if the surviving trade in goods and services between countries was continuing in an orderly way. But, as if we didn’t have enough problems, the future of the international body responsible for ensuring free and fair trade, the World Trade Organisation, is in grave doubt.

The eternal temptation in international trade is protectionism: please buy all our exports, but we’ll be importing as few as possible of your exports. It’s tempting because, to the voters in every country, it seems just common sense to favour your own industries over their rivals in other countries.

Only when you’ve learnt a bit of economics – about the gains from specialisation and exchange, in particular – do your realise that first, it’s the consumers of the protected products and all the local industries you don’t protect who pick up the tab, and second, when you try to steal a march on other countries, they usually retaliate, which ends up meaning you’re both screwed.

That’s why the WTO was set up: to help its 164 member countries reduce their import duties (“tariffs” as economists call them) and other restrictions on imports, and then keep them down, so all the members are better off.

As explained in a report from the Lowy Institute, prepared by Dmitry Grozoubinski, a former trade negotiator with our Department of Foreign Affairs and Trade, the WTO has three main roles.

First, the negotiation of successive “rounds” of mutual reductions in tariffs and import bans or quotas by all the members. After the establishment of the Geneva-based General Agreement on Tariffs and Trade (GATT) after the end of World War II, eight multilateral rounds of reductions were negotiated.

In the early rounds, the members were mainly the developed countries and they concentrated on reducing the tariffs on manufactures that had built up in the 1930s as countries tried to use protection to end the Great Depression, but succeeded only in making it worse.

The result of the rounds was hugely increased trade between the rich countries, which many economists believe contributed greatly to the post-war period of rapid economic growth, rising living standards and full employment, but which ended with the coming of “stagflation” – high inflation and unemployment – in the mid-1970s.

By the “Uruguay round”, completed in 1994, the negotiations had broadened to cover textiles, agricultural subsidies, services and intellectual property. Many developing countries had joined the agreement and benefited from the liberalisation of trade in clothing and textiles, and rural products.

But the round’s most spectacular achievement was turning the GATT into the World Trade Organisation, still based in Geneva. Many more developing countries joined, as did China in 2001.

The WTO’s second role is to monitor member countries’ compliance with the rules agreed on during the rounds. One rule is that once a tariff reduction has been agreed on, it’s then “bound” and mustn’t be increased.

But the most important rule is “most favoured nation”: no other country should be given a special deal. So the lowest tariff you impose on some nation must be the one you impose on every other member. Another key rule is “national treatment”: imported and locally produced goods must be treated equally.

The point of these rules is to keep world trade both free and fair; to discourage countries from backsliding and help governments resist local pressure to revert to protection. In particular, to stop small countries being pushed around by big countries.

And so you see why a middle-size country like ours has much to gain from living in a world where every country sticks to the rules – and much to lose when the big boys on the block decide to start throwing their weight around.

The WTO’s third role is to formally adjudicate trade disputes between its member countries, thereby enforcing its rules. Serious disputes go to a court-like “dispute settlement body” and, if necessary, to an “appellate body”.

So, what’s the problem? Why is the WTO in deep trouble? Because, in Grozoubinski’s words, “all three pillars are wobbly, and had been long before the Trump administration started taking a sledgehammer to them. Unquestionably, however, the picture in 2020 is grim.”

The first role – negotiating further rounds of reduced barriers to trade – is, he says, “hopelessly stalled”. The “Doha round” was launched in 2001, but was unable to reach agreement, partly because it’s much harder for so many developed and developing countries to find common ground. The last attempt to make progress was in 2013.

Meanwhile, countries have shifted from seeking multilateral agreements to doing any number of bilateral (misnamed) “free-trade agreements,” which breach the spirit if not the letter of WTO rules such as “most favoured nation”.

The second role – monitoring members’ compliance with the rules – “relies on international peer pressure for the bulk of its enforcement,” but the world is in the grip of a trade war between the United States and China, meaning the US has gone from decades of getting everyone else to agree on sensible rules and stick by them to ignoring any rules it finds inconvenient in its quest to “make America great again”.

As for the third role – a binding dispute settlement mechanism – in December the US used a procedural blockade to render the WTO’s appellate body “impotent and unable to convene the required quorum of three panellists,” thus rendering the formerly legally binding system of arbitration optional.

If that wasn’t enough, the US is refusing to approve the organisation’s budget, and Congress has bills that would withdraw the US from the WTO (but which are unlikely to be passed). The outfit’s director-general has resigned, and any member could sabotage his replacement. The next conference of trade ministers has been delayed until at least 2021.

And all this is happening at a time of pandemic and escalating protectionism. Well done, chaps.

The tables have turned in our economic dealings with the world

If you know your economic onions, you know that our economy has long run a deficit in trade with the rest of the world which, when you add our net payments of interest and dividends to foreigners, means we’ve long run a deficit on the current account of our balance of payments and, as a consequence, have a huge and growing foreign debt.

Except that this familiar story has been falling apart for the past five years, and is no longer true. In that time, our economic dealings with the rest of the world have been turned on their head.

Last week the Australian Bureau of Statistics announced that we’d actually run a surplus on the current account of $8.4 billion in March quarter. Does that surprise you? It shouldn’t because it was the fourth quarterly surplus in a row.

But that should surprise you because the first of those surpluses, for the June quarter last year, was the first surplus in 44 years. And now we’ve clocked up four in a row, that’s the first 12-month surplus we’ve run since 1973.

Of course, when the balance on a country’s current account turns from deficit to surplus, its net foreign liabilities to the rest of the world stop going up and start going down.

What’s brought about this remarkable transformation? Various factors, the greatest of which is our decade-long resources boom, which occurred because the rapid development of China’s economy led to hugely increased demand for our coal, natural gas and iron ore.

A massive rise in the world prices of those commodities, which began in 2004 and continued until 2011, prompted a boom in the construction of new mines and gas facilities which peaked in 2013. From then on, the volume of our exports of minerals and energy grew strongly as new mines came online.

But while our mining exports expanded greatly, the completion of the new mines and gas facilities meant a fall in our extensive imports of expensive mining equipment. As a consequence, our balance of trade in goods and services – which between 1980 and 2015 averaged a deficit equivalent to 1.25 per cent of gross domestic product – has been in surplus ever since.

The rise of China’s middle class gets much of the credit for another development that’s helped our trade balance: strong growth in our exports of services, particularly inbound tourism and the sale of education to overseas students.

When our country has gone since white settlement as a net importer of foreign financial capital – which has been necessary because our own savings haven’t been sufficient to fund all the physical investment needed to take full advantage of our country’s huge potential for economy development – it’s not surprising we have a lot of foreign investment in Australian businesses and have borrowed a lot of money from foreigners.

In which case, it’s not surprising that every quarter we have to pay foreigners a lot more in interest and dividends on their investments in our economy than they have to pay us on our investments in their economies.

This “net income deficit” – which is the other main component of the current account - has grown enormously since the breakdown of the post-World War II “Bretton Woods” system of fixed exchange rates prompted us to float our dollar in 1983 and started a revolution in banks and businesses in one country lending and investing in other countries, including the rise of multinational corporations.

That was when Australia’s net foreign debt started rising rapidly and the net income deficit began to dominate our current account. The net income deficit has averaged a massive 3.4 per cent of GDP since the late 1980s.

It hasn’t changed much since the tables started turning five years ago. Except for one thing. The rapid growth in our superannuation funds since the introduction of compulsory employee super in the early 1990s has seen so much Australian investment in the shares of foreign companies that, since 2013, the value of our “equity” investment in other countries’ companies has exceeded the value of more than two centuries of other countries’ investment in our companies.

At March 31, Australia had net foreign equity assets worth $338 billion. You’d expect this to have significantly reduced our quarterly net income deficit, but it hasn’t. Why not? Because the dividends we earn on our investments in foreign companies aren’t as great as the dividends foreigners earn on their ownership of our companies. Why not? Because our hugely profitable mining industry is three-quarters foreign-owned.

If you add our net foreign equity assets and our net foreign debt to get our net foreign liabilities, they’ve been falling as a percentage of GDP for the past decade. If you look at the absolute dollar amount, just since December 2018 it’s fallen by more than 20 per cent.

If all this sounds too good to be true, it’s certainly not as good as it looks. The final major factor helping to explain the improvement in our external position is the weakness in the economy over the 18 months before the arrival of the virus shock.

The alternative way to see what’s happening in our dealings with the rest of the world is to focus on what’s happening to national saving relative to national (physical) investment. That’s because the difference between how much the nation saves and how much it invests equals the balance on the current account.

Turns out that national investment has fallen in recent times (business investment is weak, home building has collapsed and government investment in infrastructure is falling back) while national saving has increased (households have been saving more, mining companies have been retaining much of their high profits, and governments have been increasing their operating surpluses).

So much so that the nation is now saving more than it’s investing, giving us a current account surplus. But this is a recipe for weaker not faster “jobs and growth”.

Too soon to say how hard virus will hit economy

To judge by the gyrations of the world’s sharemarkets, the coronavirus has us either off to hell in a handcart or the markets are panicking about something bad that’s happening, but they’re not sure what’s happening, how long it will last or how bad it will end up being. I’d go with the latter.

So would Reserve Bank deputy governor Dr Guy Debelle. He said in a speech this week that there’s been a large increase in the financial markets’ "risk aversion and uncertainty".

"The virus is going to have a material economic impact but it is not clear how large that will be. That makes it difficult for the market to reprice financial assets," he said.

That’s central-bankerspeak for "they’ve got no idea what will happen". Which is hardly surprising, since no one else has, either. More from Debelle’s speech as we go.

But understand this. Farr’s law of epidemics, developed in the mid-19th century, says that the number of cases of a new disease rises and then falls in a roughly symmetrical pattern, approximating a bell-shaped curve.

Depending on how quickly the disease spreads, the bell can have a steep rise and fall or a shallow one. Epidemiologists seek to make the bell as shallow as possible by slowing the disease’s spread. This allows the health system to avoid being overwhelmed – reducing the likelihood of panic and chaos, and making it more likely those who most need medical attention get it.

In theory, it allows more time for the development of a vaccine or useful drugs, but the World Health Organisation has said it will take about 18 months for a coronavirus vaccine to be widely available.

At this stage, the main way of slowing the spread is "social distancing" – reducing the contact between people by cancelling sporting events, closing schools or workplaces or ordering people to work at home. Of course, many people are doing their own social distancing by staying away from restaurants and bars.

The virus has now arrived in most countries. Its spread is well advanced in China, Iran, Italy and South Korea, but much less so in Singapore and Hong Kong, where the authorities got in earlier with their social distancing measures.

Such measures, however, cause considerable inconvenience, especially to parents, and disruption to the economy – both to the production of goods and, more particularly, services, and to their purchase and consumption. Not to mention the associated loss of income.

Some of this economic activity may merely be postponed – so that there’s a big catch-up once the epidemic subsides. But much of it – particularly the performance of services (if you miss a restaurant meal or a haircut you don’t catch up by having two) – will be lost forever.

Obviously, China is central to the story for both the world economy and ours. China’s economy was hit hard by the virus and the drastic but belated measures to slow its spread, though the number of cases does seem to have passed its peak and rapidly declined. Debelle said "the Chinese economy is now only gradually returning to normal. Even as this occurs, it is very uncertain how long it will take to repair the severe disruption to supply chains."

The globalisation of the world economy in recent decades is a major part of the story of this virus. It means people in any part of the world are almost instantly informed about unusual things happening anywhere else in the world. It’s good to be better informed, but sometimes it can be frightening.

For another thing, globalisation has greatly increased the trade between countries, particularly trade in services, such as tourism and education. Trade in services has been greatly facilitated by the emergence of cheap air travel.

It’s all the overseas air travel everyone does these days that has caused epidemics that break out in one part of the world to spread around the world within a few weeks. More pandemics has become one of the big downsides of globalisation.

And when governments try to limit the spread of a virus by banning the entry of people from countries where the virus is known to have spread widely, this disrupts and damages those of that country’s industries who sell their services to foreign visitors.

(When the government stops you supplying a service to willing buyers, economists classify this as a shock to the "supply side" of the economy. When your sales fall because customers become more reluctant to buy whatever you’re selling, that’s a "demand-side shock" to the economy.)

Our imposition of a ban on non-residents entering Australia from China has hit our tourism industry and our universities. Debelle said that, since January, inbound airline capacity from China has fallen by 90 per cent. Until recently, he said, tourist arrivals from other countries had held up reasonably well, "but that may no longer be true".

The Reserve estimates that Australia’s services exports will decline by at least 10 per cent in the March quarter, roughly evenly split between tourism and education. Since services exports account for 5 per cent of gross domestic product, this suggests the travel ban will subtract 0.5 percentage points from whatever growth comes from other parts of the economy during the quarter.

Another consequence of growing globalisation is the emergence of "global supply chains" – the practice of multinational companies manufacturing the components of their products in different countries, before assembling them in one developing country and exporting them around the world.

China is at the heart of the supply chains for many products. So Debelle’s remark about the delay in repairing "the severe disruption to supply chains" is ominous. The Reserve’s business contacts tell it supply chain disruptions are already affecting the construction and retail industries – but there’s sure to be more of this "supply-side shock" to come.

And the shock to demand as - whether through virus-avoidance, necessity or uncertainty - consumers avoid spending money, has a long way to run. But, Debelle said, it’s "just too uncertain to assess the impact of the virus beyond the March quarter".

Why surpluses aren't necessarily good, or deficits bad

According to the Essential opinion poll, only 6 per cent of people regard the size of the national surplus as the most important indicator of the state of the economy. I think that’s good news, but I’m not certain because I’m not sure what “the national surplus” is – or what the respondents to the poll took it to mean.

They probably thought it referred to the balance on the federal government’s budget. But the federal budget is not yet back to surplus and, in any case, it can’t be the national surplus because it takes no account of the budgets of the state governments that, with the feds, make up the nation.

Assuming respondents took it to be the federal budget balance, its low score is good news about the public’s economic literacy, but bad news for Scott Morrison and Josh Frydenberg, who are hoping to make a huge political killing when, in September next year, they expect to announce the budget finally is back in surplus.

The pollies are assuming that voters know nothing more about the economy than that anything called a surplus must be a good thing, whereas anything called a deficit must be very bad.

Actually, no economist thinks all surpluses are good and all deficits bad. Sometimes surpluses are good and sometimes they’re bad. Vice-versa with deficits. It depends on the economy’s circumstances at the time.

But the confusion doesn’t end there. There are lots of measures in the economy that can be in deficit or surplus, not just governments’ budgets. When I wrote a column some weeks back foreshadowing that the current account on the nation’s balance of payments would probably swing into surplus for the first time in 44 years, some people assumed I must be referring to the federal budget.

Wrong. The federal budget records the money flowing in and out of the federal government’s coffers – it’s bank account. The “balance of payments” summarises all the money flowing into and out of Australia from overseas – covering exports, imports and payments of interest and dividends in and out (making up the “current account”), and all the corresponding outflows and inflows of the financial payments required (making up the “capital and financial account”).

The trick is that, thanks to double-entry bookkeeping, the balances on the two accounts making up the balance of payments must be equal and opposite. So the longstanding deficit on the current account was always exactly offset by a surplus on the capital account.

And that means the (probably temporary) current account surplus was matched by the capital account swinging from surplus to deficit. Oh no.

Although Australia has been a net importer of (financial) capital almost continuously since the arrival of the First Fleet, for the June quarter we became a net exporter, lending or investing more money in the rest of the world than the rest of the world lent or invested in us.

If you tell the story of this change in plus and minus signs from the current account perspective, it’s mainly that the resources boom has greatly increased our exports, while the slowing in the economy’s growth means our imports of goods and services are also weak.

But there’s also a story to be told about why the capital account has gone from surplus to deficit. As Reserve Bank deputy governor Dr Guy Debelle explained in a speech at the time, the composition of the inflows and outflows of financial capital have changed a lot since 2000.

Since Australia has always been a recipient of foreign investments in our businesses, by June this year, the value of the total stock of that equity investment amounted to a liability to the rest of the world of $1.4 trillion.

But the value of our equity investments in the rest of the world amounted to assets worth $1.5 trillion. So, when it comes to equity investment, the latest figures show we had net assets of $142 billion.

The fact is, the value of our shares in them overtook the value of their shares in us in 2013. That’s a remarkable turnaround from the previous two centuries of being a destination for foreign investment.

Why did it come about? Mainly because of our introduction of compulsory superannuation. Our super funds have invested mainly in local companies, but they’ve also invested a lot in the shares of foreign companies.

For the most part, however, our seemingly endless string of current account deficits has been financed by borrowing from the rest of the world. By June, our debt to foreigners totalled $2.4 trillion. Their debt to us totalled $1.3 trillion, leaving us with net foreign debt of a mere $1.1 trillion.

There was a time when Coalition politicians carried on about that debt – owed more by our banks and businesses, than our governments - rather than the (much smaller) debt of the federal government, only about 55 per cent of which is owed to foreigners.

Why does our huge net foreign debt rarely rate a mention these days? Because it’s always made economic sense for a young country with huge development potential to be an importer of financial capital – it’s part of what’s made us so prosperous.

Because all the debt we owe is denominated in Australian dollars or has been “hedged” back into Aussie dollars – meaning a sudden big fall in our dollar would be a problem for our creditors, not us.

But also because, though our net foreign debt keeps growing in dollar terms, our economy is also growing – and hence, our ability to pay the interest on the debt. That’s a sign that, overall, the money we’ve borrowed has been put to good use.

Adding our net foreign assets to our net foreign debt gives our net foreign liabilities. Measured against the size of the economy (nominal gross domestic product), our net foreign liabilities reached a peak of about 60 per cent in 2009, but have since fallen to about 50 per cent.

If you think surpluses are always good, prepare for great news

Don’t look now, but Australians’ economic dealings with the rest of the world have transformed while our attention has been elsewhere. Business economists are predicting that, on Tuesday, we’ll learn that the usual deficit on the current account of the balance of payments has become a surplus.

If so, it will be the first quarterly surplus in 44 years. If not, we’ll come damn close.

You have to be old to appreciate what a remarkable transformation that is. Back in the 1980s we were so worried about the rise in the current account deficit and the foreign debt that it was a regular subject for radio shock jocks’ outrage. They knew nothing about what it meant, but they did know that “deficit” and “debt” were very bad words.

By the 1990s, Professor John Pitchford, of the Australian National University, had convinced the nation’s economists that the rises were a product of the globalisation of financial markets and the move to floating exchange rates, and weren’t a big deal.

By now, economists have become so relaxed about the “balance of payments” that it’s rarely mentioned. So news of the disappearing deficit will be a surprise to many.

To begin at the beginning, the balance of payments is a summary record of all the monetary transactions during a period that have an Australian business, government or individual on one end and a foreign business, government or individual on the other.

The record is divided into two accounts, the current account and the capital and financial account.  The balance on the current account is always exactly offset by the balance on the capital account. If one has a deficit of $X billion, the other must have a surplus of $X billion, so that the balance of (international) payments is in balance at all times.

As a Reserve Bank explainer says, the current account captures the net flow of money resulting from our international trade. The capital account captures the net flows of financial capital needed to make all the exporting, importing and income payments possible. These flows during the period change the amounts of Australia’s stocks of assets and liabilities at the end of the period.

To work out the balance on the current account, first you take the value of all our exports of goods and services and subtract the value of all our imports of goods and services, to get the balance of trade.

Then you take all the interest income and dividends we earnt from our investments in foreign countries and subtract all the interest and dividend payments we make to foreigners who’ve lent us money or invested in our companies.

The result is the “net income deficit” which, after you’ve added it to the trade balance, gives you the balance on the current account. As Michael Blythe, chief economist at the Commonwealth Bank, noted this week, that balance has been a deficit for 133 of the past 159 years.

Why do we almost always run a deficit? Because our land abounds in nature’s gifts, and there’s great opportunity to exploit those gifts and earn wealth for toil. What we’ve always been short of, however, is the financial capital needed to take advantage of all the opportunities.

Moving from poetry to econospeak, for pretty much all of our modern history Australia has been a net importer of (financial) capital, as Reserve deputy Dr Guy Debelle said in a revealing speech this week.

Because we don’t save enough to allow us to fully exploit all our opportunities for economic development, we’ve always drawn on the savings of foreigners – either by borrowing from them or letting them buy into Australian businesses.

Blythe says “the shortfall reflects high investment rather than low saving. By running current account deficits, we have been able to sustain a higher [physical] investment rate than we could fund ourselves. Economic growth rates and living standards have been higher than otherwise as result.”

True. And Debelle agrees, noting that Australia’s rate of saving is on par with many other advanced economies. (So don’t let any silly pollies or shock jocks tell you a current account deficit means we’re “living beyond our means”.)

Be sure you understand this: a current account deficit is fully funded by the corresponding surplus on the capital account, which represents the amount by which we needed to call on the savings of foreigners because the nation’s physical investment in new housing, business plant and structures, and public infrastructure during the period exceeded the nation’s saving (by households, companies and governments) during the period.

But if all that’s true, how come we’re expecting a current account surplus in the June quarter? It’s a combination of long-term changes in the structure of our economy that have been working to reduce the deficit, and temporary factors that may push us over the line.

Debelle says that between the early 1980s and the end of the noughties, the deficit averaged the equivalent of about 4 per cent of gross domestic product. But it’s narrowed since 2015 and is now about 1 per cent of GDP.

Most of this change is explained by the trade balance. It averaged a deficit of about 1.25 per cent of GDP over the three decades to 2015, but since then has moved into surplus. It hit record highs during the three months to June, totalling a surplus of $19.7 billion for the quarter.

The resources boom has hugely increased the quantity of our minerals and energy exports, and there’s been a temporary surge in the price we’re getting for our iron ore. At the same time, the end of the investment phase of the resources boom has greatly reduce our imports of mining and gas equipment.

The rise of China and east Asia also means protracted strong growth in our exports of education and tourism.

At the same time, the net income deficit has widened a little in recent years but, at 3.4 per cent of GDP, is in the middle of its range since the late 1980s.

The marked reduction in the current account deficit overall means that Australia’s stock of net foreign liabilities (debt plus equity in businesses) peaked at 60 per cent of GDP in 2009 and has now declined to 50 per cent. But that’s a story for another day.

Trump's mad trade war has a hidden logic

Simple economics tells us Donald Trump’s stated reasons for starting a trade war with China make no sense. But more advanced economics tells us it’s no surprise he’s 'P’d off' over China’s economic rise.

Trump complains that the United States buys more from China than China buys from the US, meaning his country runs a trade deficit with China. He sees this as an obvious injustice and a sign China is cheating.

But economics teaches that bilateral trade imbalances are natural and normal, the inevitable consequence of countries’ differing “comparative advantage”. (Australia’s strength is rural and mineral commodities, for instance, whereas China’s is manufacturing.)

What matters is a country’s trade with all its trading partners. But, even here, economics teaches it’s not necessarily bad for a country to run an overall trade (or, strictly, current account) deficit.

Why not? Because a country runs a current account deficit when its investment in new homes, business equipment and public infrastructure exceeds its ability to fund this investment with its own saving by households, companies and governments, thus requiring it to call on the saving of foreigners.

Conversely, a country runs a current account surplus when it saves more each year than it needs to fund that year’s investment spending, thus allowing it to lend some of its saving to foreigners.

Because some countries (such as China, Germany) save more than their profitable investment opportunities can take up, they run current account surpluses most years.

On the other side of the coin are countries (the US, Australia) that have more profitable investment opportunities than their savings can cover, so they run current account deficits most years.

Put the two groups together and – at least in theory – the world’s annual saving flows to the most profitable investment opportunities to be found on the planet, thus leaving everyone in the world better off.

But a deputy secretary of the Department of Prime Minister and Cabinet, Dr David Gruen, noted in a recent speech that, at a more advanced level of analysis, some of the recent tension over trade is a consequence of the strong and sustained growth of Asian economies, including China.

“As economies in our region have grown and moved up the value-added chain, they have increasingly competed with more entrenched, influential and valuable industries in advanced countries [such as the US],” Gruen says.

When rapidly developing countries embrace some new technology, the consequent increase in their productivity constitutes an increase in their real income (because they’re producing more output per unit of input).

This should also help raise the income of the developed countries with which they trade, since the rich guys are usually getting access to imports that are cheaper than they can produce themselves.

“While some advanced-country industries [and their workers] have undoubtedly been harmed by a rising Asia-Pacific, a rising Asia-Pacific has also meant more demand for other goods and services from advanced countries [as the developing countries spend some of their higher income on imports from the rich world],” Gruen says.

So better technology and increased trade between the rich and poor countries don’t reduce the real incomes of the advanced countries, but they are likely to change the distribution of income.

More income is likely to flow to the owners of capital and to highly skilled workers, while some lower skilled workers’ real incomes stagnate or fall.

“Such disruption is likely to continue as technology makes it easier to trade services across borders, and economies in the Asia-Pacific become increasingly sophisticated. Some of these newly threatened advanced-economy jobs rely on intellectual property or skills premiums, providing an economic rent worth protecting.

“It is no surprise that the generally open-trade stance of those in places like Silicon Valley sits alongside [Trump’s] demand for strong enforcement of intellectual property rights,” Gruen says.

And, although the rich world is better off with free trade, as technology continues to bring down natural barriers to trade in sectors previously considered “non-tradeable” – particularly services – politically influential opposition to free and open trade is likely to continue, he says.

But there’s a second implication of the economic rise of Asia I bet you haven’t thought of. “It makes less sense for the largest economy in the world to bear the costs of maintaining an open trading system as its economy becomes a relatively smaller share of global output.

“Free trade is a 'public good' – we all benefit from it, but each country has an incentive to shift the cost of maintaining it to others.

“The United States shouldered that burden when it was the world’s largest economy. When you are half the global economy you tend to benefit wherever in the world trade is occurring.

“The logic of [it] continuing to do so is now less compelling. The rules-based [trading] system, including the World Trade Organisation, emerged at a time when the US was the dominant global superpower."

Small or medium-sized economies with limited bargaining power in global markets (such as us) are better off with free trade – even when other countries are being protectionist. Why? Because protecting a few of your industries against imports hurts the rest of your industries more than it hurts the countries whose imports you don’t take.

But that’s not always true for large economies with significant market power, such as the US. They can sometimes use tariffs to drive down the prices other countries charge them for imports.

How? Their market is so lucrative the country supplying the imports absorbs some of the cost of the tariff to keep its retail prices competitive. The lower price of imports across the docks improves the big country’s terms of trade, increasing its real income.

Get it? The US has less to lose from an outbreak of protectionism than do smaller countries like us. That’s why the rest of us have to put more effort into preserving and abiding by the WTO’s “rules-based system” and Trump isn’t quite the madman he seems.

Closing out the world won't fix our problems

Talk about a slow burn. It's 10 years since the beginnings of the global financial crisis, the greatest economic collapse any of us will ever see. Things ought to be back to normal by now, but they aren't.

The world is still picking through the wreckage, deciding what should be kept and what dispensed with. What needs to be done differently to restore normality and ensure there's never another disaster like that one.

A lot of people were surprised the retribution didn't happen at the time: bankers sent to jail, famous economists and their theories discredited, presiding politicians pushed out to pasture, their reputations in tatters.

For a long time, it looked as though the same people who brought us the disaster were kept on to clean up the mess. "Sorry about that. Poor execution. Nothing wrong with the basic policies, of course. Won't let it happen again."

Now, however, there's a revolt by disillusioned and angry punters evident in many developed countries: the Americans voting in an outsider oddball like Trump, the Brits voting to quit the European Union then knackering the government trying to arrange it, the French electing a president from neither of the two main parties, the Germans re-electing Mummy Merkel, but only after reducing the combined vote of her party and the main alternative to their lowest share since the war.

It's a similar story in Oz, where last year's election saw one voter in four avoiding the two main parties and the resurrection of One Nation to scourge the establishment.

Fancy footwork by the Rudd government at the time allowed us to escape the GFC with only a few scratches. Turns out it's not that simple. The economy's been below par ever since and, for the past four years, our growth in wages has been as weak as in the other advanced economies.

Trouble is, when the pressure for change comes from the grassroots rather than frank admission of failure on the part of the policy elite, the great risk is that we'll flip to populism – policies that are popular because they sound like they'd make things better, when they wouldn't really because they misunderstand the deeper causes of the problem.

Much of the discontent has centred around globalisation – the breaking down of barriers separating countries.

Globalisation is a popular target because it can be blamed for the fall in jobs in manufacturing as well as the admission to our country of people who look different and have strange habits. Are they taking our jobs or just taking over our country?

But though it's true that some of the jobs lost in manufacturing have shifted to other countries (providing employment and income to people much poorer than any of us), our compulsive fear of foreigners blinds us to the much greater role played by automation.

As Dr Andrew Leigh, federal Labor's shadow assistant treasurer and a former economics professor, writes in a new book for the Lowy Institute, Choosing Openness, advances in technology have been shifting jobs from the farm to the cities, and now from manufacturing to the services sector, continuously since Australia became a federation.

This means attempting to "make Australia great again" by restoring protection – reducing our openness to the world – can't work. We'd have trouble establishing many new factories, and those we did would employ a lot more machines than workers.

What restoring protection would do, however, is raise the prices of all the goods we protected – starting with cars, clothing and footwear – worsening the cost of living of all working people.

It's too easy to forget the benefits of globalisation along with the costs.

Apart from being a bit too late, trying to return to White Australia would rob us of greater human links with rapidly developing Asia, where we all know our best hope of future prosperity lies.

Overall, we've gained more than we've lost from the successive waves of new technology, as well as from the way we opened our economy to the world in the 1980s. Trying to re-erect the shutters would be a costly mistake.

Overall, employment has just kept growing – which is not to deny that many less-skilled men formerly employed in manufacturing have not been able to find satisfactory employment.

The sensible conclusion is that there have been losers as well as winners, but little has been done to help the losers – with the winners required to do more to kick the tin.

"The chief challenge," Leigh says, "is to deal with the inequality that can accompany technological change and economic openness.

"This is not just a matter of fairness; it is also essential if we are to deal with the political backlash against openness.

"A spate of studies in economics and psychology have shown that humans exhibit loss aversion [we prefer to avoid losses more than we prefer making gains] and are more conscious of headwinds than tailwinds.

"Open markets require egalitarian institutions," Leigh concludes.

He's right. This is the key principle of reform we lost sight of after the departure of Hawke and Keating.

Why global trade growth has slowed

One thing you can be sure of is that international trade grows much faster than the world economy. It's the classic proof of growing globalisation, and it's been happening for ages. Except that it seems to have stopped.

For two decades from the mid-1980s, world trade – measured as exports plus imports – grew at more than double the rate of growth in gross world product.

Between 1986 and 2007, the volume of trade grew at an average annual rate of 3.4 per cent of world real gross domestic product, meaning it went from being equivalent to almost 30 per cent of gross world product to almost 60 per cent.

But then it dipped sharply in 2008 and 2009, thanks to the fall-off in trade after the global financial crisis and the onset of the Great Recession.


It bounced back in 2010 but, since 2011, its growth has been only a little faster than world production of goods and services.

In the decades before 1986, the volume of trade grew faster than production, but at much slower rates than in the two decades that followed. That's how we know to date the modern era of globalisation – the breaking down of economic barriers between national economies – from the mid-80s.

So, why has trade growth slowed so noticeably, and is this merely cyclical (temporary) or is it structural (lasting)?

According to a study by the Organisation for Economic Co-operation and Development, a fair bit of both.

The study estimates that about 40 per cent of the slowdown between 2011 and 2015, as compared with the period from 1991 to 2007, is explained by the weak growth of demand in the global economy.

In particular, the crisis saw a sharp fall-off in businesses' investment spending on new physical capital – which happens to be import-intensive – but it hasn't recovered all that much in the years since then.

But that leaves roughly 60 per cent of the slowdown explained by deeper, more structural forces, ones that won't just go away if we wait a few more years.

Part of the explanation is that, in the two decades before the crisis, certain factors contributed to making trade growth exceptionally strong, but these factors have now lost their force.

The biggest cause of this exceptional growth in trade was various measures to reduce tariff and non-tariff restrictions on trade.

In 1989, and partly at Australia's instigation, the Asia Pacific Economic Co-operation partnership between 21 countries was established to promote free trade.

The European Union moved to a single market in goods, services, labour and capital in 1992, increasing trade between its members. Because Europe consists of a number of separate countries, it's highly (international) "trade intensive" in a way that America – composed of states rather than countries – or even Australia, isn't.

In 1994, the "Uruguay round" of multilateral negotiations – the biggest of the many rounds of reductions in protection organised by the General Agreement on Tariffs and Trade since World War II – was reached.

This round extended membership of the GATT from the developed countries to about 150 developing countries – thus doing much to increase trade between the two groups. It also reached trade agreements covering new areas such as textiles, agriculture, services and intellectual property.

And, for good measure, the round turned the GATT into the World Trade Organisation.

The North American Free Trade Agreement between the US, Canada and Mexico began in January 1994.

And also hugely important to the growth of trade, China – now the world's second-largest trading nation – joined the WTO, cutting much of its protection as a condition of entry.

A second factor promoting the growth of trade in the two decades before the crisis was the widespread development of "global value chains" – value as in "value-added" – under which manufactured goods (cars, for instance) are assembled in one country using parts from many countries.

As trade liberalisation measures slowed in about 2000, continued growth in trade was supported by China's rapid emergence into the world economy.

By the second half of the noughties, however, these structural sources of growth had waned.

In this century, the WTO's Doha round of multilateral negotiations, launched in November 2001, has ground to a halt. According to the study, this halt in liberalisation explains about a quarter of the slowdown in the growth of trade between 2011 and 2015, compared with 1991 to 2007.

Many bilateral and regional trade agreements have been signed since then, but the only really significant agreement, the Trans Pacific Partnership, signed in February 2016, has since been scuttled by US President Donald Trump.

Add to this, "creeping protectionism from myriad small measures" in various countries, which has put trade liberalisation into reverse.

The spread of global value chains seems to have reached its limit, even declined.

Meanwhile, China's period of export-led growth has ended, with its authorities now aiming for growth led by domestic demand.

So what happens next, and what should be done?

The study says some cyclical recovery in the growth of trade is likely but, without further trade liberalisation, a return to the glory days seems unlikely.

"Trade", it reminds us, "and the related expansion of global value chains, boosts [economic] growth through increased productivity, by improving resource allocation, increasing scale and specialisation, encouraging innovation, facilitating knowledge transfer, fostering the expansion of more productive firms and the exit of the least productive ones."

All true. But, as the study acknowledges, the benefits of increased trade aren't spread evenly between or within the countries involved.

As a consequence of this – and the politicians' failure to ensure the losers from globalisation were compensated by the winners – the electorate in many rich countries is "increasingly polarised into pro- and anti-globalisation groups".

We have a lot of ground to make up before much enthusiasm for further globalisation returns.

Why we needn't worry about our massive foreign debt

When you consider how many people worry about the federal government's debt, it's surprising how rarely we hear about the nation's much bigger foreign debt. When it reached $1 trillion more than a year ago, no one noticed.

That's equivalent to 60 per cent of the nation's annual income (gross domestic product), whereas the federal net public debt is headed for less than a third of that – about $320 billion – by June.

Similarly, when you consider how much people worry about the future of the Chinese economy, American interest rates and all the rest, it's surprising how little interest we take in our "balance of payments" – a quarterly summary of all our economic transactions with the rest of the world.

Note, I'm not saying we should be worried about our foreign debt. We already do more worrying about the federal government's debt than we need to.

No, I'm just saying it's funny. Why do we worry about some things and not others?

Short answer: the politicians don't want to talk our "external sector" because it sounds bad. The economists don't want to talk about it because they know it isn't bad.

But since we're on the subject – and since Reserve Bank deputy governor Dr Guy Debelle gave a speech about it this week – let's see what's been happening while our attention's been elsewhere.

If you're unsure of the difference between the two debts, it's simple. The federal net public debt is all the money owed by the federal government to people, less all the money people owe it (hence that little word "net").

According to Debelle, about 60 per cent of all bonds issued by the feds is owed to foreigners and 40 per cent to Australian banks and investors. About a quarter of all bonds issued by the state governments is held by foreigners.

In contrast, the nation's net foreign debt is all the money Australian businesses and governments (and any other Aussies) owe to foreigners, less what they owe us. (For every $1 we owe them, they owe us 52¢.)

But how did we rack up so much debt?

Long story. Let's start with the balance of payments, which is divided into two accounts. The "current" account shows the money we earn from all our exports of goods and services, less the money we pay for all our imports, giving our "balance on trade".

Our imports usually exceed our exports, giving us a trade deficit. This deficit has to be funded (paid for) either by borrowing from foreigners or by having them make "equity" (ownership) investments in Australian businesses or properties.

Of course, when we borrow from foreigners, we have to pay interest on our debts. And when foreigners own Australian businesses, they're entitled to receive dividends.

The interest and dividends we pay to foreigners, less the interest and dividends they pay us (actually, our superannuation funds and Australian multinationals), is the "net income deficit".

We've been running trade deficits for so long, and racking up so much net debt to foreigners, that the net income deficit each quarter is much bigger than our trade deficit.

But add the trade deficit and the net income deficit (plus some odds and ends) and you get the deficit on the current account of the balance of payments.

The money that comes in from various foreign lenders and investors to cover the current account deficit is shown in its opposite number, the "capital and financial account".

Because the price of our dollar (our exchange rate) is allowed to float up and down until the number of Aussie dollars being bought and sold is equal, the deficit on the current account is at all times exactly matched by a surplus on the capital account, representing our "net [financial] capital inflow" for the quarter.

It turns out that, in the years since the global financial crisis of 2008-09, the current account deficit has narrowed.

In the 14 years to then, it averaged 4.8 per cent of GDP. In the years since then it's averaged 3.5 per cent. And in calendar 2016 it was just 2.6 per cent.

Why has it narrowed? Well, Debelle explains it's mainly a reduction in the net income deficit component of the overall deficit, which is at its lowest as a percentage of GDP since the dollar was floated in 1983.

The rates of interest we're paying on our foreign debt are lower because Australian – and world – interest rates are a lot lower since the crisis. And our dividend payments to foreign owners of Australian companies fell as the fall in coal and iron ore prices hit mining company profits.

That's nice. But while ever we have any deficit on the current account, our foreign debt will grow, and it already exceeds $1 trillion. Isn't that a worry?

Not really. It's not growing faster than our economy (GDP) is growing, and thus our ability to afford the interest payments.

More to the point, the current account deficit is just the counterpart to all the foreign capital flowing into Australia and helping us develop our economy faster than we could without foreign help.

The proof that such a massive debt doesn't mean we're "living beyond our means" is, first, that the nation – households, businesses and governments combined – saves a high proportion of its income rather than spending it on consumption.

Everything the nation saves each year is used to fund new investment in houses, business structures and equipment, and infrastructure. This investment is further proof we're not living beyond our means.

In fact, the nation invests more each year than we save. Huh? Well, the extra funding is borrowed from foreigners.

You can call it the surplus on the capital account of the balance of payments, or the "net foreign capital inflow" or – get this – the current account deficit.

Big change ahead for China and our export challenge

You don't need me to tell you we lucked out when we sited our island continent not too far from China. But will our luck hold?

Or, more pointedly, what do we have to do to ensure we stay lucky?

A major report, released this week, Partnership for Change, seeks to answer that question. It was prepared jointly by Professor Peter Drysdale, of the East Asian Bureau of Economic Research at the Australian National University, and Zhang Xiaoqiang, of the China Centre for International Economic Exchanges, with strong support from both governments.

Actually, our location on the edge of Asia is only half our good luck. The other half was discovering our island is rich in high quality, easily-won minerals and energy.

As a result, our economy has proved a fabulous fit with the re-emerging China. As the report explains, "Australia and China are deeply complementary trading partners".

Our "comparative advantage" is opposite to China's. A country has a comparative advantage in producing a particular item if it can do so at lower opportunity cost than other countries face.

"Australia has a large natural resource base relative to its population [so it] therefore specialises in the production of primary goods for export, and uses the proceeds to purchase labour-intensive and other manufactured goods," the report says.

"Conversely, China has a large labour supply, but relative to its population has smaller endowments of natural resources and accumulated capital. For this reason, China's industrial development was built on labour-intensive production, which it exchanges with Australia for imports of scarce resources."

And what a successful partnership it's been. In the space of not much more than a decade, China has become our biggest trading partner. It takes about 35 per cent of our exports of goods and services, and supplies almost 20 per cent of our imports of goods and services.

China is so big - its population is 56 times ours - and has been so successful in pursuing this growth strategy it's now the second biggest economy in the world (the biggest, if you allow for differences in purchasing power), the biggest trading nation and the world's biggest producer of manufactured goods.

But nothing stays the same. The resources boom that saw our trade with China grow so dramatically has reached its final stage. Prices for coal and iron ore have now fallen back.

The period of massive investment in new mines and natural gas facilities is ending, with construction spending falling sharply. The last stage is big growth in the quantity of our mining exports, with large increases in natural gas exports (mainly to China) still to come.

The boom was ended by big increases in the supply of commodities (from our competitors as well as us), but also by a slowing in China's demand as its need for more steel peaked.

So, after a period of huge expansion in our mining sector, our economy is making the adjustment back to normal, where most growth in production and employment comes from the ever-expanding services sector.

This is happening, with a few bumps. But, as part of its progress to full economic development, China is going through a much more dramatic "transition".

The report says China is "shifting its growth drivers from investment, exports and heavy industry to consumption, innovation and services".

"Chinese production is shifting from a model based on adaptation and imitation of goods, services and technologies developed elsewhere, to a model based on domestic innovation", it continues.

Part of this involves a shift from labour-intensive, low-tech, low-value manufacturing to more advanced, high-tech, high-value manufacturing.

This has already started.  Over the 20 years to 2015, low-tech manufacturing's share of China's total exports of goods has shrunk from almost half to less than 30 per cent.

So the big question is whether, now China is changing direction, it will still be the gold mine it's been for us so far.

China will still need to import a lot of our natural resources, even if its demand for those resources won't be growing as fast.

The report notes that, with prices so far down, our share of China's import market has increased markedly. Huh? It's because, compared with our competitors (including local Chinese mines), we're such an efficient, low-cost producer.

The report has modelled three scenarios for our trade with China over the next 10 years. Drysdale stresses the results aren't exact, but give us an idea.

The "baseline" scenario, where existing trends continue without much change, would see our exports to China grow by 72 per cent, while China's exports to us grew by 41 per cent. (All these figures are in real terms.)

The pessimistic scenario sees China's annual growth falling below 5 per cent during the decade. Even so, our exports to China would grow by 28 per cent, while their exports to us grew by 20 per cent.

The optimistic scenario, however, would see our exports to China grow by 120 per cent, while their exports to us grew by 44 per cent.

And the catch? Both countries would need to engage in supply-side (production) reforms to make it happen.

For China, this would involve reforming its banks and financial system, reforming its state-owned enterprises, and liberalising the capital account of its balance of payments by lifting restrictions on money flows and allowing a freer-floating exchange rate.

For us, it would involve increasing competition in sheltered industries, openness to foreign investment and skills, and facilitating investment in social and physical infrastructure.

These are what we'd have to do to make real our dream of getting our share of all the extra demand for fancy food and services coming from China's by-then massive middle class.

Here we'd be battling against a different and much bigger range of competitors than we face in the commodities market. You wonder if our spoilt business people are up to it.

China still our advantage in a dismal world

We are living in an era of exceptionally weak growth in the world economy. We can now look back and see that era began after the global financial crisis in 2008. We can look forward and not see when the era will end. It could be years, for all we know.

Naturally, this continuing global weakness has its effect on us. So we shouldn't blame ourselves for our own weaker growth relative to our earlier performance. Rather, we should recognise that, relative to the other developed economies, we've been doing pretty well.

But we do need to remember that, compared with the others, we have a secret weapon: our strong economic links with China.

Nigel Ray, a deputy secretary of Treasury, spelt out the unusual features of the world we've entered in a speech this week. He notes that "global growth has struggled to regain sustained momentum post-global financial crisis, and global aggregate demand remains weak".

This is despite monetary policy (interest rate) settings in nearly all the major economies remaining "extraordinarily accommodative", and global public debt increasing since the crisis.

Official forecasters have continued to downgrade prospects for global growth, he says. The International Monetary Fund downgraded its forecast in its January update - the 17th downgrade in five years.

Now get this. Slower world growth has been accompanied by a number of trends that can be seen across the global economy: slower growth in international trade, weak business investment, slower productivity growth, slower population growth in the advanced economies, low inflation, and lower expectations about future inflation.

Wow. That's the sort of poor performance you expect to see briefly at the bottom of a world recession, not as a semi-permanent state.

We knew that slower growth in the working-age population as a result of population ageing would mean slower economic growth, but now official forecasters in other countries are also reconsidering their view of long-run "potential" growth in gross domestic product (just as we've done recently, cutting it from 3 per cent to 2.75 per cent).

For the other countries, "this partly reflects the ongoing legacy of the global financial crisis - such crises have long-lived effects on investment in productive capital and on labour markets, increasing structural unemployment and lowering labour force participation rates".

In other words, if business goes for some years under-investing in new and improved capital equipment, this diminishes the economy's production capacity. And when some workers go for years unable to find another job, they tend to lose their skills and the self-discipline that goes with having to turn up to work on time every day and do as you're told.

But it's not only the after effects of a protracted recession. Ray says recent estimates by IMF economists suggest that productivity growth was slowing in the advanced economies even before the GFC.

More recently, we've noticed that the "convergence" between the emerging and the advanced economies (as the emerging economies catch up by growing at a much faster rate than the advanced countries) that we've seen since the turn of the century is showing signs of stalling.

If that happens, it means slower global economic growth and could have other undesirable consequences.

It happened that Reserve Bank deputy governor Dr Philip Lowe gave a speech in Adelaide on the same day, adding to Ray's description of the strange state the world economy finds itself in.

Lowe noted that, although the official interest rate in the United States has been increased for the first time in nine years, the Bank of Japan has unexpectedly moved its rate into negative territory.

In doing so it joined the European Central Bank, the Swiss National Bank, the Swedish Riksbank and the Danish central bank with negative interest rates. And there's an expectation in various countries that yet further monetary easing will take place.

Lowe says that, in earlier decades, it was very rare for central banks to worry that inflation and inflation expectations were too low.

"Yet today we hear this concern quite often, and the 'unconventional' has almost become the conventional," he says.

But back to China and the special advantage it gives us in a dismal world. Ray says we have a higher proportion of our exports - about 32 per cent of our exports of goods - going to China than any other advanced economy does.

Twenty years ago, China's economy was less than a third of the size of America's. Today it's the largest economy in the world when you measure it according to "purchasing power parity" (as you should).

China's rate of growth may be slowing, but it remains one of the fastest growing economies in the world.

What many foreign observers don't seem to understand is that, just as we are "rebalancing" our economy from mining-driven to other sources of growth, so the Chinese are doing something similar, shifting from growth based on heavy industry, investment and exports, to growth based on service industries, consumer spending and imports.

It's possible the Chinese economy could falter as it makes this transition, but they'll get there in the end and this is why it's possible for us to shift from selling them mainly minerals to selling them the goods (fancy Western foodstuffs) and, particularly, the services their growing middle class demands.

We've been talking about this for years, but now it's actually happening. Ray says China is already our largest destination for services exports, taking about 14 per cent of them last financial year.

China is now our second largest source of overseas visitors, and their visitors spend far more than average. More than a million Chinese tourists arrived in 2015.

But get this: those million visits represented only about 1 per cent of China's overseas tourism market. They are so big relative to us that just a tiny share of their market is a big deal in helping us keep growing.

Where the jobs will come from

It's a question doubting customers have been asking me through the whole of my career: but where will all the jobs come from? We worry about jobs, convinced there's never enough of them.

Whenever we're in a recession, with unemployment high and rising, people simply can't see how we'll ever get it down again.

In the more recent resources boom, a lot of people got jobs in faraway places helping to build new mines and natural gas facilities, but we knew that wouldn't last.

Mining now accounts for about 10 per cent of the value of the nation's production – gross domestic product – but it still employs only about 2 per cent of the workforce.

When the three foreign car makers announced in 2013 that they'd be ending Australian production later this year or next, the familiar cry went up: where will the new jobs come from?

It was a question I used to find hard to answer, but now I don't. When I started in this job more than 40 years' ago, there were 5.8 million people in the workforce. By now it's more than doubled to 11.9 million.

So the jobs did come, despite 40 years of worrying that they wouldn't. Where did they come from? I could work out from the figures how many came in which particular industries, but I'll skip to the bottom line: virtually all the extra 6 million jobs came from the services sector.

Where will the jobs be coming from in the years ahead? Same place. Indeed, they already are.

Our most recent worry has been where our economic growth would come from now coal and iron ore prices are falling and no new mining construction projects are taking the place of completing projects.

But the evidence is coming in. We're experiencing strong expansion in parts of the vast services sector, which is generating lots of extra jobs.

Whereas mining – and farming and, these days, even manufacturing – are capital-intensive, and so provide few jobs, service industries are labour-intensive, and so provide lots of 'em.

From a job-creating perspective, the trouble with physical things – "goods" – is that it's been relatively easy to use machines to replace workers, whereas you still need a lot of people to provide services, even when those people are given better machines to help them.

The other trouble with goods industries is that there's a limit to how many things – clothes, cars, fridges, laptops – you want to own. Time has shown there's almost no limit to the number and kinds of services we'd like others to perform for us.

Did you know there's such an occupation as "lactation consultant"? There used not to be, but there is now.

These are the reasons why almost all the extra jobs being created are in the services sector.

Last year, total employment grew by a very healthy 300,000 jobs, more than half of them full-time.
Research by Professor Jeff Borland, of the University of Melbourne, has found that more than 90 per cent of these jobs occurred in the private sector.

This private sector growth was concentrated in NSW and Victoria, whereas the growth in public sector employment was concentrated in Queensland and South Australia.

But where did the additional jobs come from? Fully a third – 100,000 – were in (the mainly private sector parts of) healthcare. Then came 75,000 in businesses providing professional and technical services, almost 50,000 in retailing, more than 40,000 in financial services and more than 30,000 in administrative and support services.

The thing to note about that list is that while some of those jobs would have been low-skilled, many – particularly those in professional services and healthcare – would have been high-skilled, well-paid and intellectually satisfying. But even the lesser-paid jobs would have been clean and safe.

So don't turn up your nose at services sector jobs.

And get this: the extra jobs went disproportionately to older workers. Although people aged 45 and above account for only 31 per cent of the overall workforce, they accounted for 57 per cent of the growth in jobs.

But wait, there's more. Though we keep hearing about the growth in the quantity of our mineral exports as the new mines come on line, we've heard far less about the growth in the quantity of our exports of services, particularly education and tourism. (We "export" services when foreigners come to Oz to receive them.)

Our services exports have benefited greatly from the fall in our dollar, which has made them cheaper to foreigners.

Last year, spending by international students on course fees, accommodation, living expenses and recreation grew by 13 per cent to more than $19 billion. Spending by foreign tourists in Australia rose by 11 per cent to almost $16 billion.

What's more, our lower dollar has encouraged many Aussies to take their holidays at home rather than abroad. We now have more tourism money coming in than going out.

You well know it was exports to China that did most to fuel the resources boom. What nobody's bothered to tell you is that it's China and its growing middle class that's doing most to boost our exports of education and tourism services.

Don't underestimate the contribution services are making to "growth and jobs".

Economy will look better when mining investment stops falling

Here's a little tip for the start of another working year: if you want to make much sense of the economy, you need a good feel for arithmetic.

Thanks to our obsession with economic growth, we're almost always focusing on the change in economic indicators like gross domestic product and its components, such as consumer spending, business investment, imports and exports. (And the figures we look at are usually "in real terms" – they've had the effect of inflation removed from them.)

So the big focus is on whether indicators have grown or shrunk since last quarter or last year and, if so, by how much. This means I often find myself writing a sentence such as "the growth in X – exports, say – accounted for more than all the growth in GDP".

Almost every time I do I get someone saying "what? how can that be true? How can the growth in a component of the total account for more than all the growth in the total?"

If that objection makes sense to you, you're showing your lack of arithmetic imagination. It's perfectly possible for one component to grow by more than the growth in the total provided some other component shrinks. Oh, of course.

Now consider this: we've been very unhappy with our "below trend" (below average) rate of economic growth in recent years, such as our growth of just 2.5 per cent over the year to September.

But everyone knows our problem is that we're having to make a transition from growth led by mining – in particular, by the massive surge in investment in the construction of new mines and natural gas facilities – to growth led by the rest of the economy.

And rough calculations suggest that the "non-mining economy" grew by about 3 per cent over the year to September.

Since we know the economy overall grew by 2.5 per cent, this means the "mining and mining-related economy" must have contracted over the year. This is hardly surprising: mining investment spending is dropping like a stone.

It's also good news. For a start, it says we've made a lot of progress in getting the rest of the economy growing strongly.

But there's another, arithmetic point. The collapse in mining investment can't go on forever. Eventually you hit bottom and can't fall any further. When that happens, the mining sector stops "subtracting from growth".

And when mining is neither subtracting from growth nor adding to it, the quite-strong growth in the non-mining economy will be all the growth we've got – and it, we can hope, will still be growing by 3 per cent a year.

In other words, the economy should speed up as soon as it loses the drag coming from the big contraction in mining investment. And that should happen by about the end of this year.

Next, have you noticed how popular it's become to measure the budget's performance by looking at the change in the level of government spending as a proportion of "nominal" (that is, before adjusting to remove the effect of inflation) GDP?

In principle, it makes sense to compare nominal government spending with the nominal size of the economy. It's saying that the size of the economy grows for various reasons – inflation, real growth, growth in the population – and it shouldn't worry us that government spending is growing for the same reasons.

It's only noteworthy when government spending is growing faster or slower than the economy.

But here's where it helps to have a feel for arithmetic. When you keep comparing an economic variable to a particular "denominator" (the number that goes on the bottom of the sum) over many years, you're implicitly assuming that the denominator (nominal GDP, in this case) moves in a reasonably steady, reliable way.

If so, any change in the ratio (the percentage) can be attributed to changes in the "numerator" (the number that goes on the top; in this case, government spending). If the denominator isn't moving in a stable fashion, then this instability could be contributing to the change in the percentage, making it hard to be sure what's going on with the numerator.

Trouble is, the resources boom has played havoc with the stability of nominal GDP. Why? Because GDP, being a measure of the nation's production of goods and services, naturally includes our production of exports.

But we know that the prices we were getting for our main mineral exports – coal and iron ore – shot up to unheard of levels in the early part of the boom, then from mid-2011 began falling back to earth.

To see how this has affected the stability of nominal GDP, consider these comparisons (for which I'm indebted to Michael Blythe, chief economist of the Commonwealth Bank). Over the nine years to 2001-02, it grew at an annual average rate of 6.1 per cent. (This would be inflation of 2.5 per cent plus real growth of about 3.5 per cent.)

We can think of that as nominal GDP's "normal" rate of growth. But then the prices boom starts and continues for the nine years to 2010-11, during which it grew at a rapid annual average rate of 7.2 per cent.

In the four years to 2014-15, however, the fallback in export prices caused nominal GDP to grow at a pathetic annual rate of 3.4 per cent – just a bit more than half what's "normal".

Get the point? The ups and downs of our mineral export prices shouldn't have any direct effect on the growth in government spending (though the boost to tax collections may have encouraged governments to be more generous on the spending side).

So the resources boom has had the effect of causing the government spending-to-GDP ratio to understate the extent of the growth in spending during the boom years, but now is overstating it.

Why it shouldn't be a bad year for our economy

Thanks for asking. Yes, I enjoyed my holiday – read some good books I'll tell you about later – but, unfortunately, didn't get far enough away from the media to avoid hearing all the gloomy news about the economy.

The Americans raised interest rates, the Chinese sharemarket fell, oil prices fell, share prices fell around the world, our dollar fell, the Chinese announced their economy was growing quite strongly, which everyone refused to believe.

Anything I've missed? Rarely has a year got off to such bad start, we were told. Might be worse than the global financial crisis, according to some guru whose name I forget. Recession will be knocking on our door, we're told.

Sorry, I'm not convinced. My guess is this won't be such a bad year for us, and next year will be quite good. Why? Because we've got a lot going for us domestically and because the bad things happening overseas won't have as much effect on our fortunes as many people have come to imagine.

It's become fashionable, particularly among our big business people, to take all the foreign economic news terribly seriously, on the assumption it has big implications for us Down Under.

I'm old enough to remember a time when most people believed that what happened to our economy was always of our own making. The Whitlam government tried to blame the recession of the mid-1970s on overseas factors, but everyone knew it was lying.

Since those far off-days, the world economy has globalised, of course, with the Hawke-Keating government doing much to open our economy to the rest of the world, particularly by floating our dollar and dismantling our protection against imports.

Another thing that's globalised is the media. When something bad happens anywhere in the world, we're told about it within an hour or two. Good news takes longer to pass on, if it gets through at all.

In the just-ended summer silly season, all the bad economic news from abroad has been a godsend to the parched local media, and we've played it for all it's worth.

But I think that, in adjusting to the globalised, joined-up world economy, we've gone too far the other way, assuming everything that happens overseas will determine our fate, that our economy is just a cork tossed on a global sea.

It's true that China's economy now has more influence on our future than the American or European economies we know more about, but even this can be overdone.

As can the media's extraordinary preoccupation with the ups and down of local and foreign sharemarkets, about which they – and we – know little. Hardly a news bulletin passes without us being told of the latest movement in the Dow, Footsie​ and Hang Seng.

The advent of compulsory superannuation saving has made our retirements more dependent on the fortunes of the sharemarket and, more to the point, made us more conscious of that dependency.

But sharemarkets have always gone up for a period and then down for a period, gone down for a while and then gone back up. Even during the market's long periods of seemingly steady rise, it's down on at least as many days as it's up.

So people who think they can learn anything useful about their affairs by listening to the nightly news to hear what happened to the market today – and then cursing when it's down – are fools. They've allowed the media to find a new way of making them feel bad.

Almost every economic event has advantages and disadvantages, producing winners and losers. When we allow a panicked global sharemarket and disaster-loving media to interpret those events for us, they soon convince us a fall in oil prices is bad news, not good, and the lower Aussie dollar is more bad news, even though it's what our economists have been praying for.

Perhaps our excessive attention to foreign news is fed by the widespread belief that countries make their living by selling things to other countries. So if other countries' economies are weak, our economy will be too, because they won't be buying much from us.

Fortunately, it ain't true. Or, to be accurate, it's 20 per cent right and 80 per cent wrong. It's true that Australians, like everyone else, make their living by producing goods and services and selling them to other people.

What's not true is that the other people have to be foreigners. Aussies will do just as well. About 20 per cent of what we produce is sold to foreigners, leaving a mere 80 per cent sold to locals.

That's why it's easy to exaggerate the effect that weak foreign demand for our goods and services will have on our economy. And the fact is that although prospects for the biggest export-oriented part of our economy – mining – are poor, the prospects for domestically oriented industries are good.

Unofficial estimates show the mining-related part of the economy is going backwards, whereas the "non-mining economy" has been growing at the healthy annual rate of about 3 per cent.

You see this in our figures for employment. Over the year to December, employment grew by more than 300,000 workers, a strong 2.7 per cent increase. The official rate of unemployment fell from 6.2 per cent to 5.8 per cent.

I'll be surprised if this steady improvement doesn't continue this year.

Economy's transition grinds on, despite quarterly bumps

What an exciting week it's been for lovers of thrills and spills in the economy. This time three months ago they were telling us it was near to subsiding into recession in the June quarter, but now they're telling us it took off like a rocket in the September quarter.

Phew, what a miraculous escape. Or what a load of cods, brought to us by those who've learnt nothing from years of watching the national accounts' gyrations in real gross domestic product from one quarter to the next.

You can either take those gyrations literally, or you can "look through" them, hoping for a better idea of what's really happening in the economy. The advantage of the first approach is that it's a lot more exciting. The disadvantage is that it convinces the public that economists know nothing and aren't to be trusted.

Let's take the story back a further three months to the March quarter. The literalists told us the economy was growing strongly because the Bureau of Statistics announced a first stab at growth in the quarter of 0.9 per cent.

Then we get growth slumping to 0.2 per cent (since revised to 0.3 per cent) in the June quarter, and now we get it soaring by another 0.9 per cent last quarter.

If you had a better feel for arithmetic than the literalists, you might think that, since the March quarter increase was a lot bigger than could have been expected, it wasn't all that surprising the June quarter increase was a lot smaller than could have been expected.

And since the June quarter increase was a lot smaller than could have been expected, it wasn't all that surprising the September quarter increase was a lot bigger than could have been expected.

It's notable that the component of GDP that explained most of the weakness in the June quarter also did most to explain the strength in the September quarter: the volume of exports.

Export volumes grew by an unusually strong 3.7 per cent in the March quarter, then fell by 3.3 per cent in the June quarter, then grew by an unusually strong 4.6 per cent in the latest quarter.

This tells us little about what was happening in the wider economy. Rather, it tells us how climate change is playing havoc with the bureau's seasonal adjustment process.

Huh? Export volumes have been growing mainly because all our new coal and iron ore mines are coming into production. Seasonally adjusted exports of coal were up in the March quarter because there were fewer cyclones than usually happen at that time of year.

They were down in the June quarter because the weather was much worse than usual. And why did they rebound in the September quarter? You guessed it: the weather was better than normal.

So those economists warning that our strong GDP growth in the latest quarter is unlikely to represent the start of a better growth trajectory are no doubt right.

But those people arguing that, since the growth in exports last quarter accounts for more than all the growth in GDP in the quarter, the domestic economy obviously went backwards and so must be very weak, aren't making a sensible comparison.

It's not sensible to give the "domestic economy" no credit for all the export growth our miners are generating, while making it bear the full burden of the sharp fall in mining investment spending.

No, to get a better idea of how the great "transition" to broader-based growth is progressing, it makes more sense to divide the economy between the mining and mining-related sector, and the rest of the economy.

Doing this shows that, whereas the latest accounts say the overall economy grew by 2.5 per cent over the year to September – a quite believable figure – the non-mining economy grew by about 3 per cent.

That is, when you put all the elements of mining together – the growth in its production and exports, the fall in its investment spending and the associated fall in imports of mining equipment – you find that, rather than accounting for more than all of it, mining is actually subtracting from overall growth.

To get a better handle on what's happening inside the non-mining sector, the Reserve Bank reported in its latest statement on monetary policy an exercise where it set aside mining – and agriculture – and divided the rest of the economy into three sectors.

First was the "goods-related" sector, composed of manufacturing, construction, utilities and distribution (transport, wholesale and retail trade). Second was the "household services" sector, including health, education, hospitality and recreation.

Third was the "business services" sector, including professional and scientific services, finance and insurance, hiring and real estate, and information and telecommunications.

The rate of growth in the household services sector has increased considerably over the past few years. It has experienced increased employment and job vacancies over the past year or more.

The rate of growth in the business services sector has picked up a bit, to be about average. It has experienced a recovery in job vacancies and employment.

So the economy's huge services sector is doing reasonably well. It's the goods-related sector where output growth remains weak, little changed for more than two years. Vacancies and employment have been little changed for about three years.

Thus there's been an accelerated shift from goods to services. And since services are more labour-intensive, while the goods-related sector is more capital-intensive, this explains why non-mining business investment has yet to recover.

It also explains why, economy-wide, we've enjoyed above-average growth in employment in spite of below-average growth in GDP for the past year or more.

So the transition to broader-based growth is proceeding. And once the huge fall in mining investment spending has come to an end, our growth figures should look a lot better than they do now. That, too, is just arithmetic.

Contrary to reports, economy battles on

Joe Hockey is right. The economic news is hardly wonderful, but the media's attempt this week to convince us the economy was perilously close to recession was sensationalist nonsense.

What set them off was news from the Australian Bureau of Statistics' national accounts that real gross domestic product grew by just 0.2 per cent in the June quarter. What they forgot to mention was that in the previous quarter it had grown by 0.9 per cent.

As Hockey says, the figures "bounce from quarter to quarter". But why let that small fact get in the way of a good scare story?

The less excitable Dr Chris Caton, of BT Investment Management, put it another way: "The weak growth for the June quarter was in part payback for the strong growth in the March quarter."

Just so. We were told, for example, that spending on home building fell by 1.1 per cent in the latest quarter, but not reminded that the previous quarter it had grown by a remarkable 5.6 per cent. There is no reason to believe the housing construction boom has ended.

We were told that the volume of exports fell by 3.3 per cent in the latest quarter, but not reminded that in the previous quarter it had grown by 3.7 per cent. Turns out the weather was unusually favourable around bulk-commodity ports in the first quarter, but unusually bad in the second.

We weren't told about these one-off negatives for growth in the June quarter, but much was made of a one-off positive: a sudden surge in defence spending, we were told, fully accounted for the quarter's 0.2 per cent growth.

(Actually, it was worse than that. Whereas total public sector spending made no contribution to overall growth in the March quarter, it contributed 0.6 percentage points in the June quarter.)

All this is why searchers after truth rather than headlines don't take quarterly changes in GDP too literally. Combine the two quarters and you get average quarterly growth of 0.55 per cent, or annualised growth of 2.2 per cent - which is probably closer to the truth.

It also fits better with a fact we were told only in passing, that the economy grew by 2 per cent over the year to June and by 2.4 per cent on average over the financial year, meaning Treasury's forecast of 2½ per cent was near enough to right - a point Hockey kept making and the media kept ignoring.

Examine the figures for the year to June and you don't find much evidence of an economy likely to collapse in a heap. Consumer spending grew by 2.5 per cent, home building by 10.4 per cent, public sector spending by 3.3 per cent.

Export volumes grew by 4.5 per cent, while import volumes fell by 0.7 per cent. In fact, apart from a small fall in the level of inventories, the only major negative contribution to growth came from business investment spending, which fell by 4.1 per cent.

That fall comes from the end of the mining construction boom, of course. It's a reminder of the truth of our position - that our transition from mining-led growth to more normal sources of growth has been far from smooth and isn't achieved yet - a truth too prosaic for the headline chasers. Growth in the low 2s is clearly well below average.

But if you dig a bit deeper you do find signs that the transition is proceeding, with help from record low interest rates and an ever-lower dollar.

For a start, there is evidence of recovery in non-mining investment. According to rough figuring by Kieran Davies, of Barclays bank, it's up by 4 per cent over the year to June, led by investment in the services sector.

Exports of services - including tourism and education - are also growing. Though little changed in the June quarter, their volume was up 7 per cent over the year, Davies says.

"With imports of services down 8 per cent over the past year as the falling exchange rate has made it more expensive to take an overseas holiday, trade in services [exports minus imports] added 0.1 percentage points to GDP in the June quarter and 0.6 percentage points over the past year."

Much has been made of the 1.2 per cent fall in "real net national disposable income per person", rightly described as the best measure of material living standards the national accounts provide. It's fallen for five quarters in a row.

Why? Because of the deterioration in our terms of trade - the prices we receive for our exports relative to the prices we pay for our imports - as coal and iron ore prices have fallen.

But it's important to see this in context. Why do so many people care so much about economic growth? I (and Joe and his boss) think it's mainly because they want to see more jobs created.

If so, real GDP - the quantity of goods and services workers are employed to produce - is a more relevant indicator than the various measures of "real income".

And the growth in GDP we've had has been sufficient to create 240,000 jobs over the year to July (including 68,000 during the supposedly knackered June quarter) and to stabilise the unemployment rate at just over 6 per cent.

It's true that the size of our real income has an effect on our spending on goods and services, and the demand for goods and services affects employers' demand for workers.

But much of the loss of income caused by lower coal and iron ore prices is borne by the mining companies (which are about 80 per cent foreign owned) and by state and federal governments (which collect lower mining royalties and company tax), rather than by the rest of us.

Times aren't easy, but we're not in bundle-dropping territory.

Lower dollar boosts services exports

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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