How to make sense of Treasury’s latest intergenerational report

Our sixth intergenerational report envisages an Australia of fewer young people and more elderly, with slower improvement in living standards, climate change causing economic and social upheaval, aged and disability care becoming our fastest-growing industry, and home ownership declining, while we spend more defending ourselves from the threat of a rising China, real or imagined.

That does sound like fun, but remember this: just as I hope many of the predictions I make will be self-defeating prophecies – because people act to ensure they don’t happen – so it is with Treasury’s regular intergenerational reports.

They say, here’s the pencil sketch of the next four decades that we get when we assume present economic and demographic trends keep rolling on for 40 years, and that present government policies are never changed.

Get it? Intergenerational reports are Treasury’s memo to the government of the day, saying things will have to change. The memo to you and me says: you may hate change, but unless you let our political masters make changes, this is how crappy life may become.

Every intergenerational report comes to the same bottom line: if you think you won’t be paying more tax in future you must have rocks in your head.

The media can’t stop themselves from referring to the report’s findings as “forecasts”. Nonsense. Forecasts purport to tell you what will happen. These reports are “projections”: if we make a host of key assumptions about what will happen, plug them in the machine and turn the handle 40 times, this is what comes out.

Remembering that Treasury demonstrates almost annually its inability to forecast in late April what its own budget balance will be in just two months’ time, June 30, let’s not imagine that anything it tells us today about 2063 could prove close to the truth, except by chance.

This is no attack on Treasury. No one’s forecasts are less wrong than theirs. It’s just saying don’t let the false confidence of the economics profession fool you. Only God knows what the world will look like in 2063 – and she’s not telling.

We’re all peering through a glass darkly, doing the best we can to guess what’s coming around the corner. How many pandemics in the next 40 years? Treasury’s best guess: none. How many global financial crises? Best guess: none.

We know from experience that the economy rarely moves in straight lines for long, but the nature of Treasury’s mechanical projections is that most curves stay straight for 40 years. Unexpected things are bound to happen. Some will knock us off course only briefly; some may change our direction forever. Some will be bad; some will be good.

The report’s single most important assumption is the rate at which the productivity of labour will improve. Until now, Treasury has avoided argument by assuming that the average rate of improvement over the next 40 years will be its rate over past 30 years.

The first report in 2002 assumed a rate of 1.75 per cent, but in later reports it was cut to 1.5 per cent. Now it’s been cut to the seemingly less unrealistic 20-year average of 1.2 per cent.

This shift makes a big difference. The first report had living standards – measured as real gross domestic product per person – climbing 90 per cent in 40 years. This report has them climbing by only 57 per cent in the next 40.

Since this is only the second of the six intergenerational reports produced under a Labor government, it’s only the second that takes climate change seriously. The other four looked into the coming 40 years and didn’t see any consequences of climate change worth taking into account.

Labor’s first report, in 2010, had a lot to say about climate change, but this report attempts to measure its effect on the economy and the budget. It estimates that climate change will cause the level of real GDP in 2063 to be between $135 billion and $423 billion less than it would overwise have been, in today’s dollars.

The report’s title has always been a misnomer. If it lived up to its name, it would deal with the intergenerational transfer of income and wealth from the young to the old – an issue that deserves much more attention than it gets.

It would talk about the way our treatment of housing favours the elderly, and how the tax, spending and superannuation decisions of the Howard government, in particular, shifted income from the young to the old.

But no. The real reason it’s called the intergenerational report is that its main purpose is to bang on about the huge effect the ageing of the population – the rise in the nation’s average age – will have on the federal budget (while ignoring any effects on the states’ budgets).

It’s here, however, that Rafal Chomik, of the ACR Centre of Excellence in Population Ageing Research at the University of NSW, has noted this overhyped story being toned down over the six reports. In 2002, the first report projected that, by 2023, the share of the population aged 65 and over would climb from 12.5 per cent to nearly 19 per cent.

Actually, it’s only up to 17.3 per cent. And the projection for 2063 is 23.4 per cent, less than the 24.5 per cent originally projected for 2042.

Another factor on which the report was too pessimistic at the start is the effect of ageing on participation in the labour force (by having a job or actively seeking one). Whereas it was expected to dive as the Baby Boomers retired, it’s now expected just to glide down.

Participation actually reached a record high of 66.6 per cent this year – who knew our response to a pandemic would return us to full employment for the first time in 50 years? – and is now projected to have fallen only to 63.8 per cent by 2063. If so, that would be higher than it was in 2002.

Chomik says the first report projected government spending on health care to reach more than 8 per cent of GDP by 2042. Now it’s projected to reach just 6.2 per cent by 2063. But, thanks to the royal commission, the cost of aged care is now expected to grow faster, to 2.5 per cent of GDP by 2063.

Which brings us to Treasury’s bottom line, the federal budget. Treasury projects that, as a percentage of GDP, the budget deficit will decline steadily until 2049, before ageing causes it to start heading back up.

Note, however, that while government spending is projected to rise by almost 4 per cent of GDP, tax collections are assumed, as always, to be unchanged.
