Underwhelming

Michael Reddell Monetary policy, Reserve Bank

An article in this morning’s Post, reporting comments from Paul Conway, chief economist of the Reserve Bank, prompted me to go and listen to the Governor’s MPS press conference. I’d largely given up watching them.

This was the most interesting bit of the article

although it was followed with more comments trying to reframe what the Bank had published in the MPS only a couple of days ago.

The Bank has been publishing a so-called endogenous track for short-term interest rates, as a central indication of what it believes to be required to deliver inflation at or near target 1 to 2 years ahead, for more than 25 years now. If the current crop of MPC members doesn’t yet understand how their numbers will be interpreted, that is more of a reflection on the MPC, and their chief economics adviser, than on the tool. (I’m not a big fan of publishing medium-term interest rate projections – never have been – but it is hardly a new or unfamiliar tool).

So when you published an OCR track that is revised up and out

you know the likely reaction, likely questions etc. And when you complement that numerical track by explicitly stating that the MPC actively considered raising the OCR at this very meeting, you shouldn’t be surprised you are going to be challenged. On a central track, where the OCR is averaging 5.65 per cent in the December quarter, that is consistent with a high probability of an OCR increase later this year.

If the Bank didn’t want people to take that interpretation (and both Conway’s comments in this article, and his and Orr’s comments at the press conference suggest they didn’t), they should have published different numbers. The comments from Conway in the Post article suggest that somehow the OCR projection track was outside their control – product of “its modelling tool” – when it has always been clear that the projections are the MPC’s, not some staff model (which itself has considerable human interventions pretty routinely). Perhaps it is different now, but in the many many years when I sat on the equivalent of the MPC, we used to spending huge amounts of time (arguably at times inordinate) on those last tweaks to the interest rate track, bearing in mind how any numbers would be read by outsiders. There was never a time when any published forecasts – and particularly for the interest rate track – were just some sort of machine-generated product.

Listening to the press conference for the first time in a while just confirmed a sense of how inadequate the MPC, and its chair, are for the job they’ve been charged with. They didn’t have a straight story to tell, and they were trying to back away from the clear implication of numbers they’d chosen to publish. To which one could add yet another appearance saying nothing of substance from the deputy chief executive responsible for macroeconomics and monetary policy at the Bank, or a Governor who chose to opine on productivity growth or the lack of it, suggesting that things were different (better) in Australia, even though recent productivity growth there has been just as weak as in New Zealand. Why are these people – having delivered us the inflationary mess in the first place – still in office? New Zealanders deserve better from officials – supposedly expert ones – delegated so much power. Apart from anything else they deserve real expertise and real accountability.

But then there was also a sense of how weak the media scrutiny was. Was it really the case that no journalist had wondered quite how economic growth was supposed to rebound, on these projections, with real interest rates already restrictive and set to rise further, fiscal policy restrictive, no help from the world economy, and with an expected further downturn in the net immigration impulse? In any case, none asked. None asked why if the OCR had helped lower the output gap by almost 5 percentage points so far, a continuing high OCR, rising further in real terms (as inflation and expectations fall but the OCR doesn’t), was only going to lower the output gap by a little more than 1 percentage point.

And remarkably no journalist asked, and no central banker mentioned, the very real lags in monetary policy. If the real OCR keeps rising to at least the middle of next year, won’t that be acting as a material drag on economic activity and inflation for a couple of years after that? And yet, on the Bank’s projections – the ones the Governor was presenting and journalists were supposedly questioning – quarterly inflation is back at target midpoint by the middle of next year, and – on the Bank’s telling – goes no lower from there.

The puzzles are real.

Excess demand and the Reserve Bank

Michael Reddell Monetary policy, Reserve Bank

After my post yesterday I had a few people get in touch, spanning the positions from what one might call extremely dovish to extremely hawkish. My key chart in that post was this one.

Pretty much any way one looked at real interest rates they (a) had been rising, and (b) on the Bank’s forecasts were set to continue to rise for another year or more, and yet – on those same forecasts – growth was set to return. It might not look like spectacular per capita growth next year, but on these numbers we are set to get back to slightly above average (for the pre-Covid decade) per capita growth before there have been any OCR cuts at all (in a period when fiscal policy is likely to be contractionary and the migration boost to demand and activity is expected to shrink). It was, and is, a puzzle.

One person objected to the use of per capita measures of GDP. As it happens, the pattern looks much the same, just a bit less marked, if one uses headline changes in real GDP. We go from an average quarterly contraction over the last five published quarters of -0.15% to quarterly growth of about 0.7% even as real interest rates rise and before the first OCR cut occurs in August next year.

The objection to using per capita numbers reflected a view – that some international agencies seem to like (the then chief economist of the OECD tried it out here a few years ago) – that it was almost inevitable that immigration surges would initially dampen GDP per capita, which would then recover over time as the migrants were absorbed. Perhaps there is something to this sort of model where many migrants are irregular or refugees, but this is New Zealand, where most migrants arrive on pre-approved work visas. Refugee numbers here are small, and illegal arrivals (as distinct from people overstaying visas) smaller still.

The New Zealand experience, over many decades, has tended to be that immigration shocks add more to demand (including derived demand for labour) than to supply in the short-run. And the experience of the last couple of years doesn’t seem inconsistent with that. There was a big unexpected influx, and yet there was no temporary dip in the ratio of employment to working age population: as it happened the absolute peak in the employment rate was in the same quarter as the estimated net migration peak (note that the Reserve Bank’s output gap estimate in fact peaked a few quarters earlier).

So I’m sticking with there being a puzzle. Where is this growth rebound supposed to be coming from, as monetary conditions tighten, fiscal policy tightens, net migration falls (further) and the world economy is assumed to jog along much as it has been?

But the real prompt for another post was looking at the output gap estimates themselves. In this week’s MPS there has been quite a big revision to the Bank’s estimates of the output gap (for the most recent estimated quarter, March 2024) and through all last year. On these numbers, only in the March quarter does the Reserve Bank think the economy crossed over to having (very slightly) excess capacity.

One could argue that it is consistent with their (prior) view that inflation has become more problematic than they realised, and harder to get down. One might also argue that perhaps the latest estimate lines up with the latest unemployment rate which, at 4.3 per cent, is probably around economists’ estimates of the NAIRU. Correct or not, a few more deeply negative GDP per capita quarters would quickly take the output gap deeply negative (monetary policy – and any other influences – has already taken the output gap down by 3 full percentage points of GDP in just 18 months.

But my interest is more in what the Reserve Bank’s revisions are now saying about just how overheated the New Zealand economy actually got in 2022. Here is a chart of the Bank’s output gap estimates over time.

As late as (say) August 2022 they thought the excess demand had peaked in late 2021 at under 3 per cent of GDP (large enough by any historical standards). Now, after successive revisions, not only is the (estimated) peak much later (September quarter of 2022) but it is much larger (4.3 per cent of GDP). All the quarters either side of that peak have also been revised up quite materially.

So big revisions upwards. But how do those estimates now compare with history? This is a chart of the Bank’s current output gap estimates this century

The economy was overheating in the mid 00s, and core inflation got a bit above 3 per cent. But it was nothing like as serious as the (now) estimated overheating in 2021 and 2022. And this was what the Bank simply totally failed to recognise for far too long (recall it was not until February 2022 that the OCR had even been raised back to the level it was just prior to Covid). Even now it is revising up its view of the extent of its own misjudgement and resulting policy mistakes. It was by far the biggest monetary policy mistake in the 34 years of Reserve Bank operational autonomy…..and no one seems to have paid any price at all (Governor and MPC members were all reappointed).

18 months or so ago the Bank came out with a review of its own performance, which unsurprisingly wasn’t very critical at all. Yes, we were told, it was clear with the benefit of hindsight they should have started tightening earlier, but it might only have been by a quarter and wouldn’t really have made much difference to outcomes. It was implausible even at the time – failing to grapple with the severity of the misread of the economy and associated capacity pressures. It has become literally incredible as time has gone on. Did others make similar misjudgements? Of course. But others weren’t delegated the power to run monetary policy, and the responsibility to get it right. No one forced them to take the job, purportedly delegated to people of real expertise.

A common response is some mix of claims that (a) other central banks were just as bad, and b) the Reserve Bank of New Zealand was relatively early in starting tightening. Even if the first claim were correct, it is no excuse: central bankers abroad also voluntarily accepted a mandate and failed to deliver. But it also isn’t really true. It is hard to get consistent output gap estimates across time and across countries, but the IMF is one source

On their current estimates – presumably different techniques to the RBNZ’s estimates – in both 2021 and 2022 New Zealand had the largest positive output gap of any of the advanced economies for which the IMF produces numbers. Imbalances of that extent occur because our Reserve Bank got it (rather badly) wrong, acting late and (for too long) sluggishly relative to the inflation pressures in our own economy (and even among this group of countries, the RBNZ was only the 3rd to start tightening; among OECD central banks it was 7th).

But accountability doesn’t appear to be something that mattered either to the previous government (concerned perhaps that suggesting the Bank had done poorly would reflect poorly on them who appointed the MPC) or to the current one (which tends to play down any role for the Bank, presumably to tar Labour with the blame for the high inflation, while claiming the credit for themselves when inflation settles down again).

And just one final (puzzling) chart. I noticed a few quarters ago (last August) that the Bank’s then output gap projections had about as much space above the zero line as below (probably a bit more below as it still hadn’t got back to zero by the end of the projection period). But this time – and it has been transitioning towards this over the last couple of MPSs – and focusing on the orange line (this week’s estimates), there is far more space above the zero line than there is below. In other words, on these numbers, we got to enjoy the excess output but don’t pay any sort of equivalent or commensurate price in lost output.

It doesn’t make a lot of sense (and would be something very different than we saw in the previous cycle, after 2008). Perhaps there really wasn’t quite as much excess demand at peak as they now think? Perhaps more pain (lost output relative to potential) will be required than they are saying (which might well come about quite easily if the implausible growth rebound they are projecting just doesn’t occur over the next few quarters).

I’m really not sure what is going on. But it doesn’t leave one with any more confidence that the Bank knows what it is doing than we can have now about how they handled the period from mid 2020 to mid 2022, which delivered us this persistently high inflation – and attendant arbitrary wealth redistributions – in the first place.

A puzzle

Michael Reddell inflation, Monetary policy

The Reserve Bank’s Monetary Policy Statement yesterday seems to have caught the market on the hop. Such things would be less likely if (a) we had a better MPC, and (b) they actually communicated (speeches and the like). A steady flow of supporting empirical research might help as well. But immediate market surprises aren’t really my prime focus or interest.

My interest is more in things like this, showing (all using RB forecast data)

  • the real OCR (OCR less annual CPI inflation to that particular quarter)
  • real GDP growth per working age population person (the RB doesn’t provide total population forecasts, so this is a proxy for per capita GDP growth). I’ve shown the actual data in red and the forecast data in blue

On the Reserve Bank’s projections, the OCR itself does not begin to be cut until the September quarter of next year (these forecasts once again push out any easing by another quarter or so). So even in nominal terms there is no monetary policy relief for another 15 months (and the exchange rate isn’t forecast to change either). Getting a good sense of real rates isn’t so easy. Inflation expectations never got as high as headline inflation, so those really deeply negative numbers on the left of my chart might be a little misleading. But….for the last year or so both inflation and measures of inflation expectations have been falling while the OCR has not: unquestionably, the real OCR has been rising further. On the Reserve Bank’s own numbers real interest rates seem set to increase further over the next 12-15 months (after all, most inflation expectations measures are influenced somewhat by recent experiences of inflation data).

So, real interest rates keep rising, and yet on the Reserve Bank’s telling the economy starts recovering, and by next September quarter is already back to generating real growth per WAP person of 0.3 per cent per quarter (annualised rate of about 1.2 per cent, which is hardly stellar but in an economy with basically no productivity growth in recent years certainly isn’t to be sniffed at – after all in the most recent year this measure of real GDP per capita has fallen by about 3.5 per cent)¹.

Where, you might wonder, is all this recovery in growth, to not-unrespectable levels, coming from? It is a good question. It isn’t from a stronger world economy (the assumptions the Bank is using there don’t show much change in growth rates), it isn’t going to be from looser fiscal policy (and certainly not on the dated numbers the Bank has to use, pending next week’s Budget), and as I noted it isn’t going to be from monetary policy (on the Bank’s numbers: rising real interest rates and an unchanged exchange rate). Fans of the government might mention its reform agenda etc etc, but…..there doesn’t seem to be much of one, and (more importantly here) the Bank doesn’t mention one as any sort of explanation. If anything, business confidence etc is weakening, with no sign of some contagious outbreak of animal spirits and associated entrepreneurship and investment. Oh, and the impulse to demand from the unexpected and very large surge in immigration isn’t going to be repeated (again on RB forecasts). The Bank’s forecasts have net migration halving from the rate experienced in the second half of last year.

The story just doesn’t ring true. I don’t think anyone doubts that the big increase in interest rates over the period to May last year (when the OCR got to the current 5.5 per cent) has played a significant part in the very weak economic performance of the New Zealand economy over the last 18 months (see chart). And we know – and the Reserve Bank often tells people – that there are non-trivial lags: monetary policy does not have its full effect on real economic activity anything like instantly, and a lag of perhaps 18 months is often cited. And although there is an argument that unexpected changes in interest rates might matter, no one really doubts that a persistent period of interest rates at any particular level (away from some conception of neutral, and these rates are above neutral on the Bank’s own telling) is going to have material economic impacts. So what is it that leads the Reserve Bank to think that we are now through the worst (of the GDP per capita contractions) and are on our way back to growth? I read the (very short) Economic Projections chapter in the Monetary Policy Statement and there was no hint of an explanation there either.

And then when the OCR does finally come down (in their projections) there isn’t much sign of a robust economic response to that either – unless the Bank thinks the lags are so long those effects won’t be seen until after mid-2027. But in that case, we’d be right back to the question: why do they think the economy is now about to pick itself up quite a lot from the deeply negative per capita GDP growth experience?

The story simply doesn’t seem to make a lot of sense. I’ve seen a few comments suggesting that the MPC is simply trying to bluff the markets – they don’t want to cut the OCR, and just needed some vaguely plausible headline numbers to back that preference. I’d be rather surprised if that was the real story, but when we have this immaculate recovery – even as monetary policy remains hostile, forecast immigration trends remain hostile, and fiscal policy is hardly supportive either – it is really hard to know quite what is going on.

As for the inflation outlook itself, I’m not really persuaded it is quite as worrying as the Reserve Bank suggests. As a couple of straws in the wind recall that construction costs are among the most cyclical (and labour intensive) parts of the CPI, and residential construction activity is probably the most cyclically variable part of the economy. With inflation in those sectors now running below historical averages, it probably bodes well for inflation in other service sectors.

Perhaps the Bank is right to worry, but it would be more persuasive in doing so if (a) they had a more compelling economic story (see above), and b) they offered more analysis and forecasting of inflation in core or underlying terms. A fair bit of the discussion in New Zealand proceeds around a tradables vs non-tradables split (and in my time, decades ago, as forecasting manager at the RB I actually introduced the first such breakdown) but…it is very uncommon internationally, has had some use when (as in times past) the New Zealand exchange rate was very volatile, but may not shed much light especially when – as at present – the adverse idiosyncratic shocks (that monetary policy might reasonably look through) are very much concentrated in the so-called non-tradables sector. Here, I’m not thinking of relatively strong rent increases, which are clearly a function of domestic demand and supply pressures, but of local authority rates increases (which have many of the characteristics of any indirect tax shock) and of insurance increases, which seem to have only a limited amount to do with anything domestic at all (and not to domestic pressure on real resources) and much more to do with adverse shocks to global risk-bearing capacity etc. They are real hits to consumer purchasing power, but would almost certainly be filtered out in any forecast of, say, trimmed mean inflation. It is quite a curious gap in the Bank’s projections that they make no attempt to do such forecasts (by contrast, and for example, the RBA does).

¹  Over the last full economic cycle (2007Q4 to 2019Q4) real GDP per working age person increased at a median annual rate of 1.1 per cent.

Reading the MPS numbers thinking about the fiscal situation

Michael Reddell Fiscal policy, Reserve Bank

The Reserve Bank doesn’t do independent fiscal forecasts so there is no news in the fiscal numbers in today’s Monetary Policy Statement themselves. The last official Treasury forecasts don’t take account of whatever the government is planning in next week’s Budget, and as the Bank notes they will need to update their assessment in light of whatever the spending and tax plans prove to be.

So I was more interested in the Bank’s numbers for the things they do forecast independently, and which in turn have implications for both the tax revenue the government could expect to collect on any given set of tax rates and for the likely expenditure pressures (from things like population growth and inflation).

One of the lines the Minister of Finance has repeatedly sought to use over her time in office is something about how much worse the economy was than they had appreciated (or had been clear) pre-election, to soften us up (it appeared) for yet more delay in getting back to fiscal surplus (see, we can’t really help it, it was done to us, and no one told us). It has always been an unsatisfactory argument (to say the least) since the previous projections (say, those in the PREFU and those in National’s fiscal plan) weren’t for a return to surplus for a couple more years anyway (2026/27) and by then whatever the forecast fiscal outcome, it is purely a matter of policy choice.

Now, the Budget numbers out next week will use The Treasury’s forecasts as their base. But here are the nominal GDP projections the Reserve Bank was making (a) at the August 2023 Monetary Policy Statement (ie the last set of forecasts pre-election), and b) today. Nominal activity is what gets taxed.

There is a slightly larger gap opening up a couple of years out (when, of course, who knows; both sets of numbers are just anyone’s guess out there) but as late as the June quarter next year the two observations are exactly the same, as they are (a 0.1% difference) for the last pre-PREFU quarter, 2023Q2.

Ah, perhaps you are thinking, but what about inflation. If there is more inflation than was previously forecast the revenue just won’t go as far.

But there isn’t anything much in that sort of story either.

There were some historical revisions late last year to the estimated level of real GDP. Those revisions don’t have any material implications for anything much, since life had already been lived through that period, and (in any case) it is nominal GDP that more closely approximates the tax base.

But in this chart I’ve shown the ratio of the RB’s latest forecasts for real GDP to those it did last August, and it is certainly true that over the full forecast period the latest forecasts are a couple of per cent weaker than last August’s forecasts.

Here is a slightly more obscure chart: the same sort of ratio but this time for the Bank’s estimates of real potential GDP per working age population. Things worsen there by about 1 per cent relative to the position thought to have prevailed just prior to the election.

And if weaker GDP per person implies some loss of productivity (some things the government might be purchasing won’t be getting relatively cheaper), it also suggests that (eg) public service wage pressures and NZS adjustments should be less than they might otherwise be.

The key point? At least on the Reserve Bank’s telling – and they could of course have a very different view than the Treasury – there just isn’t that much there. We are set to be less well-off per person than the Bank thought just prior to the election, but nominal GDP and the CPI forecasts have barely changed, and even the real output changes aren’t particularly large in the scheme of things (nothing at all like the extent of the revisions that followed in the wake of the 2008 recession). What we have, on the Bank’s numbers, is a recession and a protracted period of excess capacity (slack) that is not quite as deep, but quite as protracted, as the Bank suggested to any and all readers (Opposition politicians included) just prior to the election.

Some old documents (of no immediate interest)

Michael Reddell Uncategorized

This is really just a quick information post.

The Reserve Bank’s website has a complete set of Monetary Policy Statements from and including December 1996 onwards, but for some reason they have not put online the first few years of Monetary Policy Statements (which began being published, under the provisions of the Reserve Bank of New Zealand Act 1989, in April 1990). New Zealand’s inflation targeting regime (origins and early development here) took formal shape (with attendant legal obligations) when that Act came into effect, and the first Policy Targets Agreement between the Governor and the Minister of Finance was signed on 2 March 1990.

In the early years of inflation targeting there were (as the law required) only two Monetary Policy Statements a year. At the start, these documents were very light on specific forecast content. The Monetary Policy Statements were complemented by published Economic Forecasts documents, which had been released twice a year for some years (but which then had little impact on anything, and were once – in a meeting with the Minister of Finance I was attending – memorably disowned by the Bank’s Deputy Governor as “just the Economics Department’s view”). With the commencement of formal inflation targeting, and a growing recognition of the crucial importance of inflation forecasts in an inflation-targeting regime, the Economic Forecasts document took on a somewhat greater degree of prominence. For some years (until 1997) the Bank published both documents, in time on a schedule of alternating quarters (before eventually moving to the still-current model of four Monetary Policy Statements a year).

The Economic Forecasts documents for the period 1990 to 1997 are thus potentially of use to anyone seeking to study the entire New Zealand inflation targeting experience, and particularly the experience in the early years when we pathbreaking to some extent (often more like “groping in the murk”), and running a monetary policy implementation approach that was idiosyncratic to say the least. Neither they nor the early Monetary Policy Statements have been readily available.

I had had in my own files hard copies of some of these publications (with bits and pieces stuffed in them, including the September 1992 forecasts for which I was responsible and which the then Opposition Finance spokesman had described as “looking as though a public relations firm had written it” – on this occasion reality (notably fiscal reality) turned out better than the numbers he hadn’t liked)

But this complete set became available through the efforts of my son, who is doing an honours thesis in 2024 on some technical aspects of New Zealand monetary policy in recent decades. He requested the documents from the Bank and was provided with the full set from 1990 to 1997 (and my understanding is that it took a bit of work from the Bank, for which thanks). With his permission I am posting them here as a more permanent record and to make them generally available to anyone interested.

There is a full page, with a link on the front of this website, with links to all these documents

MPSs & Economic Forecasts from early-mid 90s

Two central banks

Michael Reddell Australia, Monetary policy, MPC

I got curious yesterday about how the Australia/New Zealand real exchange rate had changed over the last decade, and so dug out the data on the changes in the two countries’ CPIs. Over the 10 years from March 2014 to March 2024, New Zealand’s CPI had risen by 30.3 per cent and Australia’s CPI had risen by 30.4 per cent.

And that piqued my interest because the two countries have different inflation targets: New Zealand’s centred on 2 per cent per annum and Australia’s centred on 2.5 per cent.

So I drew myself this chart

Over the full 10 years, the two CPIs have increased by almost exactly the same amount, but they haven’t kept pace with each other steadily over that full period. Up to just prior to Covid, the Australian CPI had been increasing faster than New Zealand’s, as one might have expected given that the RBA had been given a higher inflation target than the RBNZ.

Now, before anyone objects, I should get in and note that in neither country is there a price level target. But if economies are subject to fairly similar shocks over a period of time one should normally expect a country with a higher inflation target to have experienced a higher cumulative price level increase than a country with a lower target.

Over the 10 years here is Australia’s CPI relative to the price level that would have been implied by being consistently at target midpoint

and the same chart for New Zealand

And in this chart I’ve put it all together

Over the half-decade or so to the end of 2019, the RBA and the RBNZ had both ended up undershooting (on average) their targets by about the same extent. If you look closely, the RBNZ was undershooting more earlier, and the RBA more towards the end of the decade, but there wasn’t a great deal in the difference.

But where the difference really becomes apparent is in the years (four of them) since Covid hit. Over that period, the RBNZ has generated/tolerated much more of an increase in the price level, in excess of what is implied by their target, than the RBA did. (And for those – like Orr – who like to try distraction with things like oil shocks, wars and rumours of wars, and supply chain disruptions, Australia faced all those too.)

There is a lot of focus in Australia – and apparently reasonably enough – on whether the RBA has yet done enough with monetary policy. It has certainly been puzzling that they reckoned they could get away with materially lower policy rates than in other Anglo countries, in the face of (still) near-record low rates of unemployment and a quite stimulatory fiscal policy. But so far, and overall, they’ve done a bit less badly than the Reserve Bank of New Zealand through the last four years taken together.

It remains somewhat remarkable how little serious accountability there has been for serious Reserve Bank policy errors, for which now pretty much everyone (except them) is paying the price. in one form or another.

(By the way, for anyone interested, the NZD/AUD exchange rate averaged 0.933 in the March 2014 quarter and 0.932 in the March 2024 quarter, so over that particular 10 year period there was no change in the real exchange rate at all.)

Words and (in)actions

Michael Reddell New Zealand economic performance

When I wrote yesterday morning’s post, highlighting how poorly both New Zealand and its Anglo peer countries have been doing in respect of productivity in recent times (ie, in the case of New Zealand, Australia, and Canada even worse than usual), little did I know that the Prime Minister was about to announce a bold new economic performance goal. I wasn’t even aware he was giving a pre-Budget speech yesterday.

But there it was

Now, read it carefully. If it were just the first sentence in 1. it would be largely devoid of content. Even pessimists, with long experience of the underperforming New Zealand economy, probably reckon that the average level of productivity in the New Zealand economy will be higher in 2040 than it is now (these are the sorts of lines that go up over decades, under all but the most adverse circumstances). But the Prime Minister doesn’t stop there. The second sentence is clearly a statement about relative performance: the Prime Minister’s “vision” is for a New Zealand where there is a net return of New Zealanders (after 50-60 years of trend (often large) outflows), because they can have a “better life” here and aren’t driven to move abroad by the lure of “higher incomes” there. His “vision” seems to be that economic growth in New Zealand over the next 16 years will be so strong that we’ll have matched – perhaps even exceeded – what is on offer abroad. As we all know, by far the largest net outflow of New Zealanders is to Australia. The “vision” seems to be to catch Australia.

Wouldn’t that be great? Australia is far from being a leading-edge economy but it is the easiest exit option for most New Zealanders, and has done much better than New Zealand for decades now. For those who are into trans-Tasman rivalries, it must be quite embarrassing for our country to have done so much worse than them, when for many decades we pretty much level-pegged.

As for the PM, he reminded us of his firm focus (“resolutely and unapologetically”) on “delivery”

So having set out a bold vision what is the Prime Minister offering as a policy programme to achieve it? It isn’t, after all, a small ambition. (By my reckoning, using IMF data, catching Australia’s GDP per capita by 2040 would require New Zealand’s per capita real growth rate to exceed Australia’s by about 1.45 percentage points each and every on average for 17 years – so if Australia managed 1 per cent average per capita real GDP growth, we’d have to average almost 2.5 per cent year in year out. Over the last 17 years we’ve managed about 1 per cent per capita real growth.)

The Prime Minister does lay out some substance on the early days

Personally, I’d give a tick to almost all those (but not too keen on allowing small panels of Cabinet ministers to decide which private sector projects get favoured treatment). It is mostly good stuff. But to a first approximation what it mostly does is undo stuff the previous government did and restore something like the policy set of 2017. But if productivity growth in the years up to 2017 was less bad than it has been here – and in Australia and Canada – more recently, we weren’t making any progress then either in closing gaps to the rest of the advanced world. And where it is still mostly prospective (“charting out a course of systematic RMA reform”), it is welcome, and sounds good, but…..we’ve heard lines about fixing the RMA before, including from the previous National government.

And that was sort of the problem with the entire economic strand of his 2040 vision. It brought to mind this

I hadn’t previously noticed the transition from “concrete goal” to “vision”, but whatever the language, it all made no difference whatsoever.

The Taskforce that was set up to advise on meeting the 2025 goal noted at the start of its first report that there had been a lot of talk over the years.

(I don’t suppose the Taskforce really believed that last couple of sentences, but…..the Prime Minister himself had been party to setting a “concrete goal” so he might as well be treated as taking it seriously.)

Of course, it all came to nothing and nothing about the goal (whether “concrete goal” or “vision”) was achieved. (I had some part in assisting the 2025 Taskforce, but the substantive issue is not the Taskforce, but the goal – which is what would greatly have benefited New Zealanders had it been seriously pursued. It wasn’t.)

Here is the summary chart, comparing GDP per capita (in PPP terms) between the two countries since 2007 (just prior to the severe recession on 2008/09). There are two different measures, but they both tell the story: no progress at all has been made in the intervening years to closing the gap in real GDP per capita to Australia.

In the short-term governments (government policy settings) can’t do much about the terms of trade, but generally Australia’s have been stronger than ours.

Productivity is more amenable to policy settings. If anything the gap has widened over the period covered by the original 2025 goal (these lines are indexed to a common value at the start of the period. Using annual OECD data, in PPP terms, the average level of labour productivity in Australia is about 28 per cent higher than that in New Zealand, larger than the gap in real GDP for capita (the latter also reflecting the higher employment rate in New Zealand).

Who knows if Mr Luxon is any more serious about his “vision” – laudable on its own terms – than John Key was about the 2025 goal. No doubt both of them would be quite happy if things happened to have turned out that way (wouldn’t we all) but Key and his government did nothing even close to being equal to the task to make it happen. There seems little basis – whether in PM’s speech, his campaigning last year, or anything about what his government is and isn’t doing now – for believing it will be any different this time. Most likely, it is just another positive-sounding rhetorical line that will disappear, even from prime ministerial speeches, almost as soon as it appeared.

It would be great to be proved wrong on that, because the people who pay the price of empty political aspirational rhetoric never matched by policy seriously equal to the task aren’t Prime Ministers, who eventually move on to gilded retirements, but the children and grandchildren of ordinary New Zealanders.

If, as he should be, the Prime Minister is serious about that aspiration of New Zealanders (net) coming home not just because mountains and beaches make it a nice place for many to live, but because economic performance means you don’t have to leave for a higher income, the concrete policies need to start matching the rhetoric. In the PM’s own words, delivery matters.

UPDATE: As if to reinforce my scepticism I came across this in a Stuff article

On the assumption that his answer has been fairly reported, really what can one say. It is just devoid of any substance whatever, and meanwhile his government in practice shows no sign of ending the corporate welfare handouts (which are what reinforce any sense of dependency, at least among the favoured firms).

Productivity growth: 4 Anglos

Michael Reddell New Zealand economic performance, Productivity

In my post last week on The Treasury’s recent note on productivity, I highlighted that the weak labour productivity growth evident in New Zealand over the last decade wasn’t something we’d shared with the OECD countries that were around our level of average productivity. This chart was from that post.

But as I also noted, it might have been worth Treasury having a look at Australia and Canada (richer and more productive than us, but with some important structural similarities, and neither in recent decades having been productivity growth star performers).

For many countries it is quite difficult to get whole-economy quarterly labour productivity data. But Australia, Canada and the UK publish such series, and I’ve done so for New Zealand (using the average of the two real GDP series and HLFS hours data). The data are all available to 2023Q4, although in all cases no doubt with the caveat of being subject to revision as fuller data emerge for the most recent periods.

First, a quick quiz. Which of the four Anglo countries do you think is which in this chart (I went back to end of 2015 to start from before the Brexit referendum)? Note that none of the lockdown period numbers are likely to be very reliable, and may just reflect differing assumptions the various statistical agencies made. But in all four countries, lockdowns are now well in the past.

The answer? And somewhat to my surprise…..best of a poorly performing bunch of countries over this eight year period was the UK, Brexit and all.

And how about the period since just prior to Covid (there is some noise in the quarterly data so I’ve used the 2019 average as the base)?

I’d usually highlight New Zealand in a different colour, but….it is hard to highlight (exceedingly close to) zero.

Given the potential for revisions I wouldn’t put much weight on it, but……for what the data are worth…..there is no reason to doubt that the recent productivity performances of New Zealand, Australia, and Canada have been rather similarly poor, and especially so since Covid.

It is worth making these comparisons for various reasons, but including because it is all too easy for partisans to highlight their own country’s experience, blaming everything on the rhetorical predilections and headline choices of whoever happens to have held office in this period. Over the full Covid period (in the chart just above), we had a Labour government, Canada had a government that seemed similarly “left wing”, but then for much of the period Australia had a centre-right Coalition government, and the UK…. has had the Tories (who sometimes appeared very similar to Ardern, but are notionally at least of the centre-right).

But lest you are tempted again by thought that everyone is just as bad as each other and global forces mean productivity growth was just impossible over this period, consider the US

They don’t produce whole-economy real GDP per hour worked data, and you’d expect the business sector to do better than the economy as a whole (ie including government). But I had look at how large the differences might be (using the annual US GDP per hour worked estimates from the OECD) and it is pretty clear that the US economy as a whole – an economy very much closer to the productivity frontier – has managed materially faster labour productivity growth over recent years than the 4 Anglos focused on in this post.

Countries can still manage robust productivity growth. Perhaps especially countries that are well behind the productivity frontier (see first chart in this post), but….apparently not with the policy mixes of the New Zealand, Australian, and Canadian governments.

The Treasury and productivity

Michael Reddell Productivity, Treasury

Late last week The Treasury released a new 40 page report on “The productivity slowdown: implications for the Treasury’s forecasts and projections” (productivity forecasts and projections that is, rather than any possible fiscal implications – the latter will, I guess, be articulated in the Budget documents). In short, if (as it has) productivity growth has slowed down a lot then it makes sense not to rely on optimistic assumptions about rebounds in productivity growth based on not much more than hopeful thinking. Fortunately, “wouldn’t it be nice if productivity were to grow faster” does not seem to be The Treasury’s style.

It was a slightly puzzling document though. The global (frontier) productivity growth slowdown has been around for a couple of decades now, and so is hardly news. There isn’t much (if anything) new in what The Treasury writes about that. But there also isn’t much new on New Zealand, and although there are a few interesting charts in the paper, there is very little attempt to get behind them and think about the fundamental economic factors that might be influencing those trends in the data. As an example, we are told “increasing business R&D raises the prospect of productivity benefits”, but there is little sign of any analysis of what it is that leads firms to choose (or not) to undertaken R&D spending (or spending now classified as R&D) in New Zealand. Much the same goes for business investment more generally. The decline in foreign trade as a share of GDP is noted, but it seems to be treated as some sort of exogenous event that just happened, with no attempt to offer an economic (or economic policy) interpretation. More generally, it was striking that neither the nominal nor real exchange rate gets even a single mention in the entire document.

Treasury seems to have been at pains to point out that this 40 page paper wasn’t intended as a policy document, or to address at all the much bigger issue of the huge and decades-long gap between New Zealand’s average labour productivity and that leading and highly productive economies. But they are, as they like to boast, the government’s premier economic advisers. And although they refer readers to their recent Briefing for Incoming Ministers, suggesting that “The Treasury’s Briefing to the Incoming Finance Minister outlines the Treasury’s strategic advice on the opportunities to lift productivity”, it is thin pickings there too. I hadn’t previously read the BIM (low expectations of such documents these days) but when I checked it, the main substantive document amounted to fewer than 30 pages (including lots of charts and full page headers) covering all areas of policy. There was, I think, two pages on productivity. Perhaps they tailored their product to the perceived interest of the customer (few recent governments have shown any serious interest in addressing the productivity failure) or perhaps the premier economic advisory agency just had little of substance to say.

One of my favourite (if depressing) charts over the years has been this one (where tradables here is primary and manufacturing components of GDP plus exports of services). It is doubly depressing because when I first saw it – devised by a visiting IMF mission – was in about 2005, when per capita tradables output had only just started going sideways.

This increased inward-looking nature of the New Zealand economy – across successive governments – gets very little attention in The Treasury’s document.

But perhaps what struck me most – and prompted me to write this post – was the near-complete absence of any discussion about productivity performance in those advanced economies that weren’t at the frontier (there is plenty of international discussion about the frontier, since the countries concerned are the US and a bunch of EU countries) but were or are about New Zealand’s level of average productivity. In fact, I suspect the impression a casual reader would get from Treasury’s document is that everyone has experienced slower productivity growth together.

And that is really, at best, only part of the story.

I put this chart on Twitter a couple of weeks ago

These were the group of OECD countries that had moderately close average levels of labour productivity to that of New Zealand at either the start or the end of the period. The period itself was simply a round number: the most recent decade for which there is complete OECD data.

And New Zealand has done really badly over that decade, so badly in fact that of these far-from-frontier economies, only Greece did worse than New Zealand. And these were all countries that, being far from the frontier, had – in principle – significant catch-up or convergence opportunities. More than a few of them realised those opportunities. New Zealand languished.

(Nor is there any mention/discussion of how the experience of Australia and Canada – both richer than us, but otherwise with some similarities around policy experiments and economic structures – have also had woefully bad productivity performance in the last five or so years. Perhaps there are lessons to be learned, insights to be gained?)

I’m not really sure what The Treasury’s purpose was in writing and publishing the productivity document was. But we – and I include ministers here – deserve better from the government’s premier economic advisory agency. The government having – sensibly in the circumstances – scrapped the Productivity Commission, we really need more than ever a high-performing Treasury. It isn’t obvious that we have one, or that it is being led by someone with the interest in or capacity to deliver excellence. Her term expires shortly
