The other day Treasury released a 29 page set of slides put together in September 2014 for an internal “Immigration Policy Forum”. The Forum discussion – probably gathering all the key people in Treasury – seems to have been designed to help Treasury come to a “clearer shared position on immigration policy”. For a time, at least, there seemed to be two schools in Treasury – a “microeconomic wing” championing the gains to New Zealand from immigration policy, and a “macroeconomic wing” – perhaps somewhat influenced by some of my arguments – uneasy about the possibility that the macroeconomic pressures (eg on real interest and exchange rates) resulting from high target rates of non-citizen immigration might be impeding New Zealand’s medium-term economic performance.
I’m not entirely sure why Treasury chose to release these slides now. They aren’t a response to an OIA request, but may have been prompted by my recent OIA request (the results of which they released the same day) asking for copies of any material Treasury had prepared on immigration since 1 April 2015. I haven’t read the OIA release results in any detail yet (there is 200 pages of material), but these slides look to provide more of an overview of Treasury’s perspective than any of the specific papers in that collection. The slides themselves don’t tell us what view the Forum reached on immigration, but from the fact that Treasury has voluntarily released them and that there is no suggestion the meeting disagreed with the proposed stance, it seems safe to conclude that the slides represented a Treasury view, at least in late 2014.
Last year, I had asked for copies of papers Treasury had provided to the Minister on the economic impact of immigration. I discussed here what they released then, noting that I had been surprised how little evidence or argumentation they had advanced suggesting that New Zealanders as a whole were getting economic benefits from one of the largest inward migration programmes run anywhere.
What about the 2014 slide pack? Is there any sign of a more in-depth assessment of the issues and arguments as they apply specifically to New Zealand? Unfortunately, not really.
There are some interesting and nicely-put-together charts. There were even a few things I didn’t know (eg there is an interesting OECD chart showing that New Zealand has the highest share of the labour force made up of temporary migrants of any OECD country).
Much of the discussion is, in principle, organized around this decision tree.
Which is more or less fine, as far as it goes, although it continues to structure debate in terms of microeconomic benefits vs macroeconomic costs, simply taking for granting that in the specific case of New Zealand there are in fact microeconomic benefits to New Zealanders.
I’m not going to devote any more space to either Option 1a (substantially increasing immigration) or Option 1d (trying to adjust the inward flow of migrants cyclically, to ease cyclical pressures on the economy). The first simply isn’t going to happen – especially while the advocates of large scale immigration to New Zealand can show no clear evidence that New Zealanders have benefited from the large scale immigration we’ve already had over many decades. And I agree with Treasury that adjusting the immigration programme cyclically isn’t particularly sensible or workable – both because the economic cycle is difficult to forecast, and because many of the fluctuations in net migration (ie flows between NZ and Australia) aren’t directly amenable to New Zealand policy measures. Monetary policy should remain the cyclical management tool of choice.
The real choices are between maintaining something like the current target level of non-citizen immigration (45000 to 50000 residence approvals a year) and reducing that target, perhaps to something more in line with the typical OECD country. Within either of those options, there are choices about how we select migrants and what sort of people we aim to bring in. At least in these slides, Treasury is more interested in these latter issues than in the former.
The challenge of identifying impacts of current level of migration is that itis difficult to specify a counterfactual – what would have otherwisehappened without the observed level of immigration.The evidence isn’t definitive enough to make a judgement about whethernet benefits would be higher from the current quantity of inwardmigration or a lower level. But it does show that composition matters.
Our key judgment is that migrant labour is increasingly likely to be a substitute for local low -skill labour, and this is an impact that we should try and mitigate.
More high-skilled migrants can benefit high-productivity firms and industries, and we are less concerned about wage and employment effects for high-skilled local labour.This is because we think:– High–skill migrant labour is more likely to complement local labour and capital, rather than substitute for it– High-skill labour will increase the skill composition of the local workforce, which is the theoretical channel through which many of the beneficial impacts of migration are achieved– To the extent there are LM impacts on competing local labour, we think there are normative policy reasons to be less concerned at that end of the earnings spectrumResearch suggests that the high – skill migration may have a positive impact oninnovation and productivity via its effects on skill composition. High – skill labour is also likely a complement for both low -skill labour and capital.We think this suggests that we should look to increase the supply of this sort of labour.
All of which might be fine if, for example, they could show that the New Zealand economy (and New Zealanders in particular) was actually benefiting from the high-skilled immigration we already have. Or if they could show how New Zealand could attract genuinely highly-skilled people in large numbers, when large numbers of our own skilled people are typically treating New Zealand as a place to leave. Or if they had engaged with the data suggesting that many skilled migrants take decades to match the earnings of comparably-skilled locals.
At one level, I don’t disagree with Treasury. If we are going to run a large inward migration programme, it is far better to do as we advertise, and make it a genuinely highly-skilled focused programme. The proportion of fairly modestly skilled people we have been allowing in in recent years seems most unlikely to benefit New Zealanders as a whole, and there are more plausible stories for widespread benefits from attracting highly-skilled migrants than low-skilled ones.
But one really needs a lot more material than is captured in these slides to reach a considered view on the appropriate level of non-citizen immigration for New Zealand. Perhaps most importantly, one would need to engage seriously with 25 years of continued economic underperformance, even though we have been running one of the largest immigration programmes around. But one would also need to show signs of thinking hard about the structural characteristics of the New Zealand economy, which continues to rely – almost as heavily as ever – on its natural resource base, not self-evidently a resource that needs (or benefits from) lots more people. One might need to show a serious willingness to grapple with such characteristics of the New Zealand economy as its persistently high real interest rates and the persistently high real exchange rate. Or to grapple with the indications of the economic underperformance of Auckland.
And there is simply none of that in these slides.
(One might even want to grapple more seriously with the housing market tensions that high levels of immigration has created. I’m quite with those who say that a first best response might be to sort out the housing supply and urban land market, but……there is very little sign of that happening, and no sign that it has successfully happened anywhere else. This isn’t just some sort of sequencing problem – urban land issues look fairly intractable, not for technical reasons, but for reasons having to do with the preferences of residents on the one hand, and planners, bureaucrats and central and local government politicians on the other. In the meantime, while people blithely talk of “immigration isn’t the problem, housing supply is”, too many people seem to be living in overcrowded accommodation, garages and even – no doubt rarely and temporarily – in cars.)
I’ve argued previously that the Productivity Commission should be asked to conduct a serious review of the economics of New Zealand’s immigration policy, in the context of the specific structural features of the New Zealand economy. The Commission seems, on its track record to date, to be prone to rehearsing – in more sophisticated language and at considerable length – current conventional wisdoms, but it remains the best-placed official agency to do some more serious work in this area and to contribute to a better-informed public debate.
Have we lost some of your postings? Apart from this the most recent is from 11 May?
Hopefully this paper in their OIA release “INCREASING THE CONTRIBUTION OF PEOPLE FLOWS TO
NEW ZEALAND’S ECONOMIC PERFORMANCE” will be useful. But at 130 pages I haven’t read it either.
I also note this comment from their Sep ’15 “Treasury Board Slides”: –
“MBIE has been making progress in spurts over the last 12 months on a strategic immigration work programme. We have had some influence on the shape and direction of that.”

I’m not sure why they aren’t visible – the posts for the previous few days are there (if one Google searches them) but, as you say, not immediately visible. I will have a dig around and see if I can find out what is wrong. Whatever it is doesn’t apply everywhere – if I read the blog on my phone all the recent posts are visible.
I also haven’t read that long Fry paper, but I assume it will be consonant with her new book – which I have read, have meant to (but haven’t blogged about), but wasn’t persuaded by.

It was a specific reference to the way that slide was structured. but more generally it was shorthand for a debate between those who buy all the arguments about productivity spillovers, economic benefits from diversity, agglomeration gains from a bigger population (the standard arguments in the international literature) and those intrigued by the ideas I was running – also dealt with in the Fry Treasury working paper – that rapid immigration-led population growth helped explain our persistently high real interest rates and high real exchange rate, in turning helping to explain why business investment has been so weak (over decades) and the tradables sector has failed to grow in a way that would allow us to catch up with the advanced countries we usually compare ourselves to.
When I first started this debate in 2009/10, when I was at Treasury, I used to pose it in a way that said, “even if those so-called micro benefits are there, as mechanisms, they look as though they have been overwhelmed by the macro imbalances that results (real int and exch rates). These days I would argue that there is little or no evidence of those “micro” benefits working in NZ at all, and see the macro imbalances as reinforcing the problem.
One of the problems for the discussion was that typical migration-focused economists gave little thought to the macro pressures issue – indeed often struggle to understand it – and the macro people (incl me back then) often hadn’t read very deeply in the specialist immigration literature.

Thanks
As the terms “micro” versus “macro” occurs fairly frequently in your articles I have had to turn to the definitions of these terminologies to refresh my mind as to what is meant in terms of what is being discussed – and find that often your useage strays somewhat from those definitions

yes, I probably should find some new terminology – it was just the shorthands we were using in the internal debates.

Treasury thinking on immigration and lack of evidence
If that presentation represents the the style of Treasury thinking NZ has a serious problem
NZ has the data. Why is it not used for factual information instead of avoiding the issue and permitting the vast acreage spent on conjecture
Customs
NZ Customs collect as points of arrival and departure significant detail as to occupation, age, nationality, purpose of trip, are you departing or intending to stay for more than 12 months, your usual or intended address
Statistics NZ has commented that nearly 20% of departure and arrival cards are not completed fully
In Short, they have the data
Immigration Department
Immigration processes and records the information relevant to all applications for residency and all visas temporary or otherwise. A number of those visas are Wealthy investor entrants with proposals
IRD
The inland revenue collects, records and holds data for many years on income of all individuals, companies and trusts, and how much tax they have contributed to NZ’s coffers
OIO
Overseas Investment Office
The identities of all the participants are collected and recorded
Applying data-matching NZ can and should obtain the following
(a) How many immigrants toss the towel in and leave within 5 years of arrival
(b) How much income has each entity earned since arrival
(c) How much income tax has been paid since arrival
(d) Has the migrant worked in and derived income from their declared skill-set
(e) How much benefit has been derived from “investment schemes”
and I could go on, but it seems there is a lack of critical thinking in the top echelons of power
As an example the Australian Government has handed the management of its property investigation over to the ATO which has all the data-matching powers and uses them adroitly. It is noted that the ATO is now back-tracking 40 years of property transaction records
The evidence is there, right under our noses. Dont we use it? Probably not, because in the words of Jack Nicholson – you cant handle the truth

A lot of that sort of data is collected and used, but it doesn’t directly answer the most important question: are we as NZers better off, or not, from such a large scale immigration programme. Answering that question convincingly isn’t easy – if it were no doubt any positive answers would be shouted from the rooftops – as requires a model (both mental and more formal) that takes account of the key channels through which one might expect gains or costs, and key relevant structural features of the NZ economy.

That is why the Australians are $40 billion overspent on their budget due to more and more beaurarcrats that have no solutions other than to research and to do more research. It is quite simple. Build more houses.

I find your point on micro camps and macro camps pretty revealing – I’d expect that it’s not that uncommon in other Treasury departments either. The other distinction this makes me think is a sort of wets vs dries; where the dries are much more inclined to come at propositions of amazing economic benefits from government policies much more sceptically.
I certainly can’t say that I’ve spent much time thinking on the subject, but this feels like an argument which the wets have won, and most likely, on the back of politics rather than dry economic arguments. It feels quite similar to the tone and level of rigour applied around the likely benefits from infrastructure expenditure, particularly light rail, or mythical skills transfer and agglomeration benefits.
But it’s hard to have an arms length interrogative discussion around subjects like this without potentially stepping on politically sensitive toes. Treasury departments still report to politicians after all, and they’re still staffed with people who have political views.
