Our current fiscal settings promise that we will eventually face a public debt explosion. A major cause would arise from the aging population. Is there anything we can do?
It has long been known that the ageing population would create future fiscal pressure. It was quantified in the first (2006) Treasury long-term fiscal projection and has been confirmed in every subsequent one. It is not simply that with relatively more elderly, the cost of New Zealand Superannuation rises markedly faster than GDP. The elderly also require more public healthcare and related social support much of which is today funded by others.
For the record, the just released 2025 Treasury Long-Term Projection calculates that given the current expenditure and revenue settings net debt would amount to two years of GDP in 2065.* Of course, the true figure is not that precise, but the order of magnitude is probably right. Whatever the ratio is, it will be acceptable to those expected to lend the debt to the government. Fundamentally, the current fiscal settings are not sustainable. A major contribution to the blowout is the aging population.
Despite the 2006 warning, very little has been done to address the challenge. Michael Cullen introduced Kiwisaver, a semi-compulsory earnings-related second-tier top-up on NZS but it will do little to reduce the fiscal pressure.
He also instigated the New Zealand (aka Cullen) SuperFund, in which the government invests financially now with the intention to draw down the fund as a bulge in the proportion of elderly comes through. Subsequent National Governments have not always paid into the fund in the way that Cullen intended.**
Meanwhile, the public remains impervious to the danger of a fiscal crisis. They seem to dismiss the challenge because they think it will not happen in their lifetimes. A consequence of Dornbusch’s law? Since the crisis takes longer to arrive than you think, you ignore it; when it happens it will be faster than you thought and you will be very angry at no one taking preventive measures (but not angry with yourself). Today’s young-uns may wake up one day to find we are (or the world is) in an economic and financial crisis which requires their retirement prospects to be ‘unexpectedly’ and severely curtailed.
What to do? The first option is to do nothing and hope that action will have to be taken after we are dead, with the cost of our sloth falling on younger generations – that has been the approach of recent decades.
The second option would be to Americanise the pension system – to abandon NZS as it was originally conceived and is understood today, replacing it with an income- or means-tested minimal income support for the poorest and leaving everyone else to fend for themselves. The Treasury tried to do this with its proposal in the 1997 referendum. Although fronted by Winston Peters, the scheme was neoliberal as set out by Roger Douglas in Unfinished Business. It was rejected by a huge majority (92.4%) of voters. I suppose it could be imposed without popular consent but that seems unlikely so I won’t critique it.
Treasury has also proposed that the level of NZS be indexed to prices rather than wages with the effect that the elderly would not share in any rise in material prosperity. (It was a part of the 1997 scheme.) Such price-indexation was imposed on benefits in 1991. The outcome was increased hardship. Whether it would be politically acceptable is for others to decide. (The Treasury is not unknown to advocate policies which it knows are politically unacceptable.) The change would give a little short-term relief to fiscal pressures, but would not resolve the longer-term pressure.
The indexation shift is likely to be a part of the resolution response to any Horrendous Fiscal Crisis (HFC). There would also be endings of various concessions (e.g. health, social support and transport), and the introduction of incomes- and/or means-testing. (Means-testing involves an assets test.) The winter energy supplement would be high on the abolition list. This is an ugly scenario – essentially an Americanisation – over which we would have little control.
That leaves two options (or both). One (the fourth in this list) would be to raise the age of entitlement. I have long been an advocate of this policy although I originally arrived at it from an equity rather than fiscal perspective. It seemed to me that as longevity increased and as those in later working age groups – the pre-elderly – became more robust, it did not make sense to give them the same state support as when the New Zealand pension system was first formulated in 1898.
I was impressed by the raising of the age of eligibility from 60 to 65 which Ruth Richardson (then Minister of Finance) and Cullen (then Opposition Spokesperson on Finance) agreed to in 1992. Well-signalled, small, incremental steps, with a provision to cover those unable to work and in hardship. Why stop at 65? Why not continue the process until some reasonable age of eligibility is reached? I suggested that might be where expected longevity would be 17 years. In 1898 that the expectation of a 65-year-old was 13 years; today it is 20 years. We do not expect to reach an expected longevity until age of about 72. Were we to adopt immediately the Richardson-Cullen process raising age of eligibility 3 months every year, we would not reach 72 until 2041. (For further detail see here and here.)
I am not arguing here for reducing the scope of the modern welfare state. Rather, I favour adapting it to changing circumstances. (Once, a single woman was eligible for the pension at the age of 55; I leave you to list the changing circumstances which made that archaic even if originally it was a humane policy.)
The National Party proposes raising the age of eligibility to 67 some years away. (I leave you to judge whether that is politically courageous or timid.) It was ruled out in the coalition agreement with NZF. It leaves the danger that one morning during an HFC, those who are 64 will wake up to find they will have to wait another two or more years before they become eligible for NZS.
The fifth option would be to claw back the incomes of the well-off elderly more than the current income-tax system (with its low top rate) does. There are potentially big gains here. On the two occasions a government tried to impose a clawback (it was called a ‘surcharge’), the public outcry was such that it backed down.
Which seems to leave us with the first option, to do nothing and wait for the HFC to do it to us.
Let me make a small suggestion which would give some flexibility for future change. Set up a special tax code for NZ superannuants. Let’s call it ‘G’ for golden oldies. (I suggested a parallel code for families with children here.)
Initially, it would have exactly the same tax regime as the existing one. Only those joining the scheme would be required to use the G code – current superannuants would not. An important reason for leaving them alone is that one cannot trust those designing the G-code to make transferring to it simple. But also it provides more certainty to the existing superannuants that their entitlements will not be undermined. Both reasons would reduce the initial antagonism to the new G-scheme.
In the long run though, the G-scheme could be changed with tax rates on upper incomes increased relative to ordinary tax rates – a clawback. (I could give a lot more detail if there was any interest.) Thus we would have an arrangement which could be used to progressively, flexibly and incrementally address the challenge of the aging population, rather than wait for the HFC to do it for us.***
* Note for Geeks. The public debt-to-GDP ratio will not be 200% as was widely reported. It may be 200% years. What separated out the good mathematicians in my class from the rest, was that the former knew they had to keep their units consistent. If you didn’t, you made egregious mistakes. Debt is a stock measured in dollars (say), GDP is a flow measured in dollars per year (say). In which case the Debt-to-GDP ratio is dollars divided by dollars per year, so its unit of measurement is ‘years’. You may think this does not matter but I have seen discussions in considerable confusion because the participants were not distinguishing stocks from flows. Part of our clumsy response to the Asian Financial Crisis of 1997 arose from the Reserve Bank not understanding this elementary mathematics.
** The economics of the Cullen fund is complicated. It requires distinguishing between the situation for a person from the situation for the economy as a whole where feedback loops are so much stronger. Do not make the ‘fallacy of composition’, which ignores these feedbacks. It led to a lot of faulty analysis during the Great Depression and probably intensified it. The critical assumption is that the Fund can make a higher return on its investments than the costs of government borrowing.
