As a parent I find it particularly disheartening to observe the near-complete indifference of governments and major political parties that might hope to form governments to the atrocious productivity performance of the New Zealand economy. If the last National government was bad, the Labour or Labour-led governments since 2017 have been worse. It is hard to think of a single thing they’ve done to improve the climate for market-driven business investment and productivity growth, and easy to identify a growing list of things that worsen the outlook – most individually probably quite small effects, but the cumulative direction is pretty clear. Before I had kids I used to idly talk about not encouraging any I had to stay in New Zealand, so relatively poor were the prospects becoming. It is harder to take that stance when it is real young people one enjoys being around, but…..at least from an economic perspective New Zealand looks like an ever-worse option, increasingly an inward-looking backwater.
One of the ways of seeing the utter failure – the indifference, the betrayal of New Zealanders – is to look at the growing list of countries that are either moving past us, or fast approaching us. Recall that for 50 years or more New Zealand was among the handful of very highest income countries on earth.
For doing those comparisons I prefer to focus on measures of real GDP per hour worked, compared using purchasing power parity (PPP) exchange rates. It is, broadly speaking, a measure of how much value is being added by firms – mostly in the private sector – for each unit of labour those firms are deploying. Real GDP per capita can be useful for some purposes – actual material living standards comparisons – but can be greatly, directly, affected, by demographics, in ways that don’t reveal much about the performance of the economy and the environment for business investment.
When I run charts here about productivity comparisons across countries I mostly use OECD data. Most – but not quite all – of what we think of as advanced economies are in the OECD (as well as a few new entrants that aren’t very advanced at all, and seem like “diversity hires”, incidentally making New Zealand look a bit less bad in “whole of OECD” comparisons). But once in a while I check out the Conference Board’s Total Economy Database, which has a smaller range of series for a rather wider range of countries, advanced and emerging. The latest update was out a few weeks ago.
As regular readers know I have highlighted from time to time the eastern and central European OECD countries – all Communist-run until about 1989 – that were catching or moving past us. I first noticed this when I helped write the 2025 Taskforce’s report – remember, the idea that we might close the gaps to Australia by 2025, when in fact policy indifference has meant they’ve kept widening – in 2009, so that must have been data for 2007 or 2008. Back then only Slovenia had matched us, and they were (a) small and (b) just over the border from Italy and Austria. The OECD and Conference Board numbers are slightly different, but by now probably four of the eight have matched or exceeded us (and all eight managed faster productivity growth than us over the last cycle). Turkey – also in the OECD – has also now passed us.
But what about the central and eastern European countries that aren’t in the OECD? As I glanced down the tables I remembered a post I’d written four years ago about Romania and comparisons with New Zealand’s economic performance. Romania had been achieving quite strong productivity growth prompting me to note
….one of the once-richest countries of the world is on course for having Romania, almost a byword in instability, repression etc for so many decades, catch us up. It would take a while if current trends continue. But not that long. Simply extrapolating the relative performance of just the last decade (and they had a very nasty recession in 2008/09 during that time) about another 20 years.
So how have things been going?
Even if we focus just on the last hard pre-Covid estimate (for 2019) they were up to about 84 per cent of average New Zealand labour productivity. If these trends continue, they’d catch us by about the end of the decade.
To be clear, it is generally a good thing when other countries succeed. It is great that these central and eastern European countries moved out from the shadow of the USSR and non-market economies and are now achieving substantial lifts in living standards. The point of the comparisons is not to begrudge their successes – which have a long way still to run to match most of western Europe – but to highlight the failure New Zealand governments have presided over. We were richer than all these countries for almost all of modern New Zealand history, and soon our economy will be less productive than all or most of them. We were also richer and better off than most or all of today’s most productive advanced economies, and now we just trail in the their wake. Even as the most productive advanced economies have experienced a marked slowing in their productivity growth in the last 15 years or so
we’ve really only managed little more than to track their slowdown – and recall that the median of these countries has average labour productivity two-thirds higher than New Zealand’s so – as in the central and eastern European countries – there were big gaps that might have been closed somewhat. Most of those countries did so, but not New Zealand.
To revert to Romania for a moment, it is not as if it is without its challenges. It ranks about 55th on the World Bank’s ease of doing business index, and has been slipping down that ranking (although still doing very well on a couple of components). Corruption seems to be a major problem. The neighbours aren’t the best either – including Ukraine and Moldova. Reading the latest IMF report (pre-Covid) there were signs of some looming macro imbalances but the latest IMF forecasts suggests a pretty optimistic outlook still, including investment as a share of GDP climbing back to about 25 per cent of GDP. Perhaps something is going to derail that productivity convergence (with New Zealand) story but it isn’t there in the forecasts at present. And if corruption has to be a drag of some sort (but how large can that effect be?) government spending and revenue are both smaller as a share of GDP than in New Zealand.
In GDP per capita terms the picture (Romania vs New Zealand) is not quite as grim. That mostly reflects differences in hours worked
Some of that is demographics, some not. Either way, hours worked are an input – a cost – not (mostly) a good thing in their own right. New Zealand struggles to maintain upper middle income living standards for the population as a whole by working a lot more hours (per capita) than many other advanced countries.
And then of course there is the difference that must be quite uncomfortable for the political and bureaucratic champions of “big New Zealand” – those politicians (both sides) just champing at the bit to get our population growing rapidly again.
Romania is a pretty big country. When this chart started it had almost six times our population. 25 years on Romania’s population is a bit under four times ours. I mentioned earlier the investment share of GDP: Romania’s is averaging a little higher than ours, even with these massive population growth (shrinkage) differences, so just imagine how much more of those investment resources are going to deepen capital per worker (even public infrastructure per citizen). (For those interested the total fertility rates of the two countries are now very similar: the differences in trend population growth are largely down to immigration/emigration.)
Now, of course, I haven’t mentioned being in the EU or being located not too far from many of the most productive economies on earth (although Bucharest to Zurich isn’t much less than the distance Wellington to Sydney). Those are advantages. Of course they are. But then why do New Zealand officials and policymakers continue to champion a (now) purely policy-driven “big New Zealand” when (a) almost nothing has gone right for that story in (at least) the last 25 years, and (b) when so much else of policy choices only reduces the likelihood of the future under such a strategy being any better?
Romania really is a success story, and I’d like to understand a bit better why (for example) it has been doing so much better than Bulgaria and Serbia. But it isn’t an isolated success story: in addition to the OECD eastern and central European economies, Croatia isn’t doing too badly either.
But – and taking a much longer span – this chart still surprised me. It draws on different database – the Maddison Project collection of historical real GDP per capita data. Since it is per capita data it includes all those differences in hours worked per capita (data which simply isn’t available for most countries in the distant past). I’ve started in 1875 simply because that is when the Romania data start. I’ve shown only the countries for which there is 1875 data (the last observations are 2016 simply because that is when this particular database stops), with the exception of China and India which I’ve added in for illustrative purposes because there are a couple of estimates for years between 1870 and 1887 which I’ve simply interpolated. The chart shows the ratio of real per capita incomes in 2016 as a ratio of those in 1875.
Best of them all. New Zealand not so much (and yes we were about the top of the class in 1875, but the New Zealand story is submergence not convergence, given how many of these countries are now richer than us).
To be clear, over the last 140+ years New Zealand has been a far better – safer, more prosperous, fairer, more open – country in which to live than Romania. Whether it will still be so for most the next century is increasingly a very open question. Our politicians seem unconcerned, and if any of them have private concerns they do nothing about them – no serious policies in government, so no serious policy reform options in Opposition. Nothing. They seem to just prefer nothing more than the occasional ritual mention.
Still on matters productivity, I finished reading last night an excellent new book on productivity: Fully Grown: Why a Stagnant Economy is a Sign of Success by Dietrich Vollrath, a professor of economics at the University of Houston. It is incredibly clearly written, and is a superb introduction to economic growth and productivity for anyone interested (I”ll be commending it to my son who has just started university economics). I’m not really persuaded by his story about the US, but it is well worth reading if you want to think about these issues as they apply to one of the highest productivity economies on earth. It suffers (as so many US books) do from being exclusively US-focused, even though there is a range of northern European economies with productivity levels very similar to (a bit above, a bit below) those in the US and one might think that their data, their experiences, might be a cross-check on some of his stories. To be clear, his focus is on a frontier economy, not ones – whether New Zealand or the central and east European ones, or even the UK and Australia – which start so far inside the frontier. But it is a very good introduction to how to think about sum of the issues, and a summary of many of the papers that the research-rich US economy generates.
