Is it our future to be China's quarry? Decision 2010

Australia's traditional economic challenges will be turned on their head in this decade.

WHAT our economy needs in the 2010s is success in balancing supply and demand. Does that sound obvious and not very hard? It's neither.

A big part of the problem is neither you nor I nor the politicians are used to thinking of the economic problem in those terms. And even when we do, we define the problem in conventional terms, failing to take account of the ultimate provider of both supply and demand: the natural environment.

Speaking at the nationwide level, when demand exceeds supply we get inflation. When supply exceeds demand we get unemployment. So we need to keep them in alignment to minimise both problems.

But both demand and supply are moving targets. The economy keeps growing, so we need to keep both demand (spending on goods and services) and supply (capacity to produce them) growing at much the same rate.

If the severe difficulties facing European economies were to spread - including to China, India and the developing world - our problem would be one of deficient demand relative to supply, leading to slow growth and rising unemployment.

But the greater likelihood is that our overarching problem will not be deficient demand but deficient supply as we struggle to greatly expand our capacity to meet developing Asia's voracious appetite for our minerals and energy.

Supply is by far the better deficiency to have. It's the problem of the prosperous and successful, not the waning and struggling. But that doesn't stop it being a problem.

In early 2008, before the global financial crisis hit, we were in the midst of a resources boom. Relative to the prices we were paying for our imports, the prices for our exports were the highest in 50 years.

Our economy was operating at close to full capacity. Unemployment was down to 4 per cent, shortages of skilled labour were emerging, factories and other businesses were flat-chat and real wages were rising, although inflation pressure was building and the Reserve Bank had pushed its official interest rate to a 14-year high.

Mainly because Asia's demand for our exports scarcely missed a beat, but also because our domestic recession was so mild, the likelihood is that the resources boom will soon resume and we'll soon return to full capacity.

Everyone assumes it is hardest to manage Australia's economy in bad times. Recessions are painful and economic managers come in for criticism, but it's the good times that are hardest to manage.

Why? It is easy to stimulate demand - with increased government spending, tax cuts and much lower interest rates - but hard to conjure up increased supply. That requires more skilled workers, housing, machines, factories, mines and offices, as well as more public infrastructure: roads, bridges, public transport, power stations, coal loaders and ports.

In the past the solution was to minimise inflation by using high interest rates or tax increases to suppress demand. But we've usually done too much too late and ended up in recession.

However, past booms have been temporary, "cyclical" events caused by brief periods of strong growth in the developed world. This boom, which began in 2003, seems more lasting ("structural") because it arises from the two most populous countries entering decades of economic transformation from underdeveloped to developed.

We're likely to go through an extended period in which supply grows rapidly - we greatly increase the economy's productive capacity. But we're already close to full employment.

Assuming Asia's strong demand for commodities continues, an increase in our capacity to produce coal, iron ore and natural gas is already in train. Business spending on physical investment will soon take its highest share of gross domestic product in half a century.

But when our labour and capital are already pretty much fully employed, the only way we can put more resources into new mines, gas terminals and related infrastructure is by taking those resources from somewhere else.

Some industries (and states) have to give up resources so the mining industry (and the states it is in) can have more resources. This doesn't necessarily mean other industries and states have to contract in absolute terms, it may just mean the lion's share of future annual growth in employment and physical capital goes to mining and the mining states.

Governments can help by adding to the supply of skilled labour (through increased training and skilled migration), well-located land for home building and necessary public infrastructure. But even though the nation's supply constraint moves out each year, and can be made a little faster, it's still a constraint. It still limits how much more we can do. If we try to exceed that limit, all we get is inflation.

A big part of the political problem governments will face is that, after 30 years of high unemployment, the public is locked into a mentality that our key problem is deficient demand, with the implication that any proposed project claimed to create jobs is unquestionably worthy of government support.

The notion that if project X is to create 500 jobs, those workers will have to be taken from jobs elsewhere is foreign to our thinking. What's more, the higher wages it needs to attract workers could provoke a wages bidding war that adds to inflation.

Can you imagine any politician saying a new project requiring 500 workers didn't sound like such a good idea? Welcome to the future challenge.

The economy has a natural mechanism for helping the needed geographical and industrial change in its structure: the floating exchange rate. By going high during resource booms, it squeezes those export and import-competing industries whose demand isn't booming.

But this automatic mechanism will need reinforcement from overt government policy. Adding to supply often involves adding to demand in the first instance. Demand can be divided into spending on consumption and spending on physical investment.

If supply constrains the demand we can accommodate without inflation, but an increased share of demand needs to be devoted to investment - in business plant, housing and public infrastructure - that leaves less room for consumer spending.

A lasting resources boom needs to constrain growth in consumer spending if it's not to involve runaway inflation. Households need to spend less and save more.

The economic managers have ways of combating inflation pressure and discouraging excessive growth in consumption (particularly spending on consumer durables such as cars and major household items, which are usually bought on credit): raise interest rates.

So the bigger and longer the resources boom, the higher you can expect interest rates to be.

Don't like that solution? A better (but only partial) substitute would be for the federal government to run ever-increasing budget surpluses even after its debt is paid back, with the money invested anywhere but in Australia.

We look like we'll need some unfamiliar and controversial policies from the next and future federal governments if we're to exploit our geological and geographical luck without coming unstuck.

And that's just the conventional analysis, which conveniently ignores the natural environment. Responding to the way economic growth is damaging the ecosystem and starting to feed back adversely on the economy will require an extra dimension of unfamiliar and controversial policies.

Population fall poses immense new challenges

Peter Costello used to say demography is destiny. Like many of the things he said, that's an exaggeration. But it is going to have a big effect on your future.

Demography is the study of human populations. In principle, it's quite separate from economics. But economists are likely to be saying a lot more about it - and boning up on it - because demographic change will have a big effect on the thing they care about most: the growth of the economy.

Actually, as you realise when you read the article by Jamie Hall and Andrew Stone in this quarter's Reserve Bank Bulletin, demographic change has always had a big effect on the growth in gross domestic product.

It's just that, because so far its effect on growth has been positive, we've been able to take it for granted. From about now, however, its effect is likely to be negative, so we'll be taking a lot more notice.

Leaving aside migration (as we will do in this article), the main factor that drives population growth is the fertility rate - the number of babies per woman. (The death rate also matters, obviously, but we'll also take rising longevity as read.)

The world's population has been growing rapidly for most of the past century, thanks to improvements in public health, medical science and economic development. But the global fertility rate has been falling sharply since the end of the postwar baby boom. From five babies per woman it's now down to about 2, thanks to the spread of effective contraception and rising living standards.

United Nations projections foresee the rate falling to two babies per woman by the middle of this century, which is lower than the replacement rate of 2.1 babies.

So the rate of growth in the world's population has been slowing for decades and, while population is expected to continue growing until the second half of this century, it will then start to decline.

Get that: some of our youngsters will live to see the world's population falling. But population decline will start earlier in some countries than others. Indeed, it's already started in Japan and Germany. And it won't be just the rich countries where population is falling.

The growth in a country's output of goods and services (GDP) can be viewed as coming from two sources: growth in the input of labour and improvement in the productivity of that labour. Three main factors determine the growth in the input of labour: growth in the population, growth in the proportion of the population that is of working age, and changes in the rate at which people of working age choose to participate in the labour force. (Again for simplicity we'll ignore changes in the participation rate.)

Over the 10 years to 2005 the United States' average growth in real GDP was 3.3 per cent a year. Turns out that 1.1 percentage points of that growth came from increased population (meaning it did nothing to raise America's standard of living) and 0.2 percentage points came from the rising proportion of the population that was of working age (here assumed to be those aged between 15 and 64).

But now Hall and Stone estimate that, over the 10 years to 2020, the average annual contribution to economic growth from population increase will be a smaller 0.9 percentage points, and the contribution from change in the working-age share will be minus 0.3 percentage points.

In other words, America's average rate of economic growth is expected to be 0.8 percentage points a year (or about a quarter) less, simply because of direct demographic change. The equivalent expected declines in the demographic contribution are 0.6 percentage points for Japan, 0.3 points for Germany and 0.2 points for Italy.

Why is America's loss likely to be greatest? Because demographic change is only now catching up with it. The others have already taken a fair bit of their medicine. It turns out that most of Japan's "lost decade" of weak economic growth is explained by its ageing and now declining population. Without that, its growth was much the same as Germany's.

So far we've tended to think of slow-growing or falling population as an issue purely for the developed countries. But Hall and Stone demonstrate that the coming decade will see demographic change making a reduced contribution to growth throughout Asia.

What's more, China's population will start to fall slowly in about 20 years' time and South Korea's population will peak in 10 year's time and then fall quite rapidly.

Looking again at the 10 years to 2005, China's economic growth averaged 8.8 per cent a year. Of this, 0.8 percentage points came from population increase and 0.6 percentage points from a higher working-age share.

Over the coming 10 years, however, Hall and Stone estimate that population's contribution to growth will slow to 0.6 points a year and the working-age share's contribution will be minus 0.3 per cent. So demography's contribution to growth will be 1.2 points a year lower than in the previous period.

Now take Korea. Demography contributed 0.7 percentage points to its average economic growth of 4.4 per cent a year in the first period, but will make a zero contribution over the coming decade.

The general story for east Asia (the five main ASEAN countries plus Korea, Taiwan and Hong Kong, but excluding China and Japan) is that demography's contribution of 1.8 percentage points (or almost half) during the 10 years to 2005 will fall to 1 percentage point in the coming decade.

But two Asian countries stand out from this general picture of demographic change making a significantly reduced contribution to economic growth over the next 10 years. Population growth in Indonesia and India will be slowing, but still relatively strong.

So the demographic contribution in Indonesia will slow only from 1.9 percentage points a year to 1.2 points a year. In India it will slow only from 2.2 points a year to 1.6 points.

Much of the demographic difference between China on one hand and India and Indonesia on the other would be explained by differences in population control policies, particularly China's one-child policy, which is about to really make its presence felt. (The main explanation for Korea, I suspect, is simply rising affluence prompting people to have fewer kids.)

But however it's explained, the likelihood is that, in about 2030, India will overtake China as the most populous country. So rest assured, economists will be saying a lot more about demography in coming years.

How Keynes, not mining, saved us from recession

You never judge economists by whether they get their forecasts right. They rarely do. But they score points in my book if they're willing to work out why they got them wrong - and make the results public.

This is what Treasury's chief forecaster, Dr David Gruen, did in a speech to the Economic Society in Sydney on Friday.

I don't hold out much hope that such exercises will help produce better forecasts in future. But they should deepen our understanding of how the economy works.

Gruen's examination of Treasury's record in forecasting real gross domestic product over the past 21 years finds there's no upward or downward bias in its errors, but its "mean absolute percentage error" is 0.93 percentage points.

When you remember the trend rate of growth is about 3.25 per cent a year, that's a high degree of error.

Last May Treasury forecast that real gross domestic product would contract by 0.5 per cent in the financial year just ending, the first time it had ever forecast "negative growth". The year isn't over yet, but the revised forecast in this year's budget is positive growth of 2 per cent. And just the first three-quarters of the financial year are showing average growth of 1.9 per cent.

But if you think all that's bad, just remember: the smarties who purport to know better than Treasury are usually worse. Consider these reactions to the forecasts in last year's budget.

Des Moore, the climate-change denying activist: "The Rudd government's budget paints an unbelievable picture of a very mild recession (only a 0.5 per cent fall in GDP next year) followed by a recovery of 2.25 per cent in the election year (2010-11) and an above-trend rate of growth of 4.5 per cent in the following year."

John Roskam, a leading libertarian: "If Prime Minister Kevin Rudd genuinely believes Treasury is conservative when it forecasts economic growth of 4 per cent within two years, then it would be interesting to know his definition of optimistic. Treasury officials are not used to being laughed at on budget night but, as soon as their growth forecasts were revealed, no other reaction was possible."

Of course, we do know that average growth in real GDP in calendar 2009 was 1.3 per cent, and Gruen has revealed Treasury's unpublished forecast of minus 0.9 per cent. This was worse than the mean of minus 0.6 per cent for 17 private sector forecasts gathered by Consensus Economics, but right on the median.

After allowing for imports and inventories, the largest contribution to growth came from consumer spending (1.4 percentage points), followed by public sector spending (0.9 points), business investment and exports (0.4 points each), with housing investment making a negative contribution of 0.3 points.

(If you're wondering how all that adds up to just 1.3 per cent, it does so with the help of a negative contribution of 1.5 points from the "statistical discrepancy". Don't groan - the national accounts are like that; it's just one of the complications forecasters face.)

It's clear most of that surprisingly strong performance was due to old-fashioned Keynesian fiscal stimulus. Consumer spending was greatly bolstered by the cash splash, while the jump in public sector spending speaks for itself. The growth in business investment was explained by the draw-forward effect of the temporary tax break.

According to Treasury's estimates, the fiscal stimulus contributed about 2 percentage points to the overall growth of 1.3 per cent last year, meaning that, without it, GDP would have contracted by 0.7 per cent.

So much for the claim the mining sector was "a key factor in keeping Australia out of recession".

If you decompose exports' contribution of 0.4 percentage points, rural commodities contributed more (0.3 points) than mineral commodities (0.2 points), with manufactures making a negative contribution.

Treasury did allow for the effect of the fiscal stimulus in its forecast, but it's pretty clear it (and everyone else) didn't allow enough.

Gruen believes it took insufficient account of the "favourable feedback loop that expansionary macro-economic policy - both monetary and fiscal - appears to have generated".

"Macro-economic policy appears to have been large enough and quick enough to convince consumers and businesses that the domestic slowdown would be relatively mild," Gruen says.

"This, in turn, led consumers and businesses to continue to spend, and led businesses to cut workers' hours rather than laying them off which, in turn, helped the economic slowdown to be relatively mild."

The turnaround in business and consumer sentiment began earlier and was a lot stronger in Australia than in other developed economies. But that's another problem for the forecasters: swings in the collective mood are probably the biggest factor driving the business cycle, but how do you predict them?

It's true, of course, that continuing demand from China played a part in keeping us afloat. Gruen notes that the Consensus forecast for "non-Japan Asia turned out to be significantly too pessimistic".

But why? Partly because the forecasters made insufficient allowance for the Asians' lack of impairment in their financial systems, but also because they underestimated the speed and size of the fiscal and monetary stimulus, particularly in Korea and China.

As well as underrating the power of Keynesian policies - which are likely to be more potent in the young and dynamic emerging economies - too many forecasters failed to see how much success the Chinese would have in switching from external demand to domestic demand, particularly spending on infrastructure.

An economy as big as China has plenty of scope to "decouple" from the developed countries - a point worth remembering when you're tempted by the latest fear, that Europe's problems will wipe us out.

Stay calm, this too shall pass

Talk about a two-track economy. Have you noticed how the government and others have been focused on the return of the resources boom, with all the tax bonanzas and challenges that could bring, while the rest of the world has been worrying itself sick about the debt problems in Europe, sending our sharemarket and the Aussie dollar tumbling?

Surely the two don't fit. Are we living in fantasyland? Is reality about to hit us on the head? Or could it be that Europe's problems don't have all that much to do with us and before long the global financial markets will stop panicking and our share prices and currency will recover?

Standard product warning: no one knows what the future holds and economists aren't good at predicting it. But my guess is the end of our world isn't nigh.

Although the Greek government was in over its head even before the global financial crisis reached its peak in late 2008 (and was fudging its figures to hide the truth), most of the other European governments now have big budget deficits and huge levels of debt because of their efforts to rescue their banks and their heavy spending to stimulate their economies.

Those national governments with rocky banks (including the United States) have, in effect, transferred their banks' debt on to their own books. So what started as excessive private debt is now excessive public debt.

I don't criticise them for this. Had they not rescued their banks the outcome would have been a lot worse. No, the real problem is that, unlike us, their affairs weren't in order before the crisis. They'd been running budget deficits even in the boom years and had high levels of debt even before they were obliged to borrow so heavily.

The particularly acute problems in Greece served to draw the attention of the world financial markets to problems in other countries - Portugal, Spain, Italy and Ireland. Even the Brits have huge debt levels.

As often happens, the markets flipped from inattention to panic. When they're in that sort of mood, all the news is catastrophic. The Chinese had jammed on the brakes to burst a property bubble, putting an end to the global recovery. The Australians had nationalised their mining industry (something like that, anyway; not sure of the fine detail).

Whenever the players in world financial markets are gripped by panic their tendency is to sell whatever shares they can wherever they can and buy US Treasury bills. Even when it's the US economy that's at the heart of the problem, they still do it.

The result is a fall in sharemarkets around the world and a rise in the value of the US dollar at the expense of most other currencies. If you remember, this is what happened after the collapse of Lehman Brothers. Our dollar went from US98 in July 2008 to US63 in November. It stayed there until March, then eventually climbed back to US92.

The likelihood is that, as the present panic subsides, our share prices will recover and our dollar will go back up (as it has already begun to). But this return of the staggers is a reminder that a lot of the underlying problems exposed by the global financial crisis are still with us, and will be for a long time.

So perhaps the recovery of sharemarkets in the months following the crisis was a bit too optimistic and this time it won't be as strong.

Certainly, the Europeans won't easily dispense with their debt problems. And the more they feel pressured by the markets to turn around their budget balances by slashing government spending and raising taxes the more they'll slow the recovery in their economies.

The Europeans' problems are compounded by the existence of the euro currency arrangement, and their efforts to hold it together may end up extracting a high price in terms of economic growth. All the troubled member-countries would be better off being able to set their own interest rates and allow their own currency to fall against those of their stronger European trading partners, but

they can't.

The Greeks are so deeply in hock their best solution would be to default on their debt and start again, but that isn't possible. Even leaving the euro would be terribly messy.

So Europe isn't likely to show much growth for the rest of the decade. But this won't hold Australia back as much as it would have in the old days. Our fortunes are now much more aligned with those of China, India and the rest of developing Asia. Are they likely to be adversely affected by Europe's troubles? My guess is, a bit but not a lot.

China's efforts to deal with its property bubble are quite circumscribed, so I don't expect its growth to suffer too much. If so, our authorities' expectations of a return of the resources boom aren't likely to be too far astray.

The thing about financial markets is they make judgments in haste and repent at leisure. If it's right that the prospects for our economy haven't been greatly impaired by the problems of the Europeans and the fine-tuning of the Chinese, eventually our strong position relative to the other developed economies will again be reflected in our higher share prices and exchange rate.

As ever, the ups and downs of the sharemarket will prove an unreliable guide to the prospects for the economy (even though the innocent souls who write headlines sometimes seem to imagine the sharemarket is the economy).

Similarly, the headline-writers' assumption that a fall in our dollar is an unmitigated evil says more about their innocence of economics than their grip on reality.

On this I'm with our farmers, manufacturers, tourist operators and education industry in hoping the dollar's return to the 90s takes as long as possible. There's more to life than overseas holidays.
