Not many good tidings….

…in the productivity numbers that is.

Statistics New Zealand yesterday released the September quarter GDP data, including the revisions to the quarterly data that stem from the annual national accounts for the year to March 2016 that were published a few weeks ago.    Headline writers focused on the quite high rates of growth for the September quarter, while more sober observers allowed for the 2.1 per cent population growth in the last year and noted that in per capita terms real GDP growth remains pretty subdued.

I dug out the data to see if there had been any productivity growth.   As I’ve noted on several occasions, the labour productivity trend in recent years has been so weak it almost seems too bad to be true.  I wondered if the picture might look better with the new data.

In Australia, the ABS reports an index of real GDP per hour worked as one of the standard suite of published series.  In New Zealand, no such luck.  So I average the two measures of real GDP (expenditure and production) and divide by hours worked from the HLFS.  Unfortunately, Statistics New Zealand upgraded the HLFS earlier this year, and in the process introduced a break in the hours worked series.  There is a step up in hours worked that is partly on account of simply measuring things differently (and probably better).  Improvements in statistics are, of course, welcome but it is a little frustrating that the agency has made no effort to produce an official break-adjusted series.   In the June quarter, hours worked rose by 2.6 per cent.  As real GDP rose by 0.7 per cent, and there has been little sign of productivity growth in recent years, I’m going to assume in the charts that follow that 2 percentage points of that increase in hours was just a result of the change in methodology.  It won’t be quite right, but it doesn’t look likely to be seriously inaccurate either, especially against the measurement challenges and revisions we always face in looking at GDP/productivity.

So here is the resulting measure of real GDP per hour worked

And, even with the data updates, there is still no sign of any material productivity growth.  It has been 4.5 years now since this productivity index got to around the current level.

There was plenty of gloomy commentary around the recent Australian quarterly GDP outcome, but in productivity terms  even after a poor quarter (in a series with some noise), Australia continues to pull away from New Zealand.  Here are the two GDP per hour worked series, starting from 2007q4, just prior to the New Zealand (and global) recession and the Australian downturn.

Our dismal productivity performance really should be getting more attention, and raising more concern, than it seems to.  But today isn’t the day for a long post on the underlying problems and possible solutions.

I’ll be taking something of a break.  There might be a few posts in the next few weeks, but something like a normal flow won’t resume until the week starting 30 January when the kids start going back to school.

In the meantime, in honour of Sunday’s Feast of the Incarnation (aka Christmas) I’ll leave you with this from John Milton’s poem

On the Morning of Christ’s Nativity
Compos’d 1629

I

This is the Month, and this the happy morn
Wherein the Son of Heav’ns eternal King,
Of wedded Maid, and Virgin Mother born,
Our great redemption from above did bring;
For so the holy sages once did sing,
That he our deadly forfeit should release,
And with his Father work us a perpetual peace.

II

That glorious Form, that Light unsufferable,
And that far-beaming blaze of Majesty,
Wherwith he wont at Heav’ns high Councel-Table,
To sit the midst of Trinal Unity,
He laid aside; and here with us to be,
Forsook the Courts of everlasting Day,
And chose with us a darksom House of mortal Clay.

III

Say Heav’nly Muse, shall not thy sacred vein
Afford a present to the Infant God?
Hast thou no vers, no hymn, or solemn strein,
To welcom him to this his new abode,
Now while the Heav’n by the Suns team untrod,
Hath took no print of the approching light,
And all the spangled host keep watch in squadrons bright?

IV

See how from far upon the Eastern rode
The Star-led Wisards haste with odours sweet:
O run, prevent them with thy humble ode,
And lay it lowly at his blessed feet;
Have thou the honour first, thy Lord to greet,
And joyn thy voice unto the Angel Quire,
From out his secret Altar toucht with hallow’d fire.

  1. As long as NZ focus is on Tourism, Milk, Meat and International students then do not expect productivity improvement. The hallmark of a service industry is excellent service which usually means more people serving and taking the trouble and the time and effort to talk to the customer.

    Banks have tried to automate the front desk and shut down branch offices in the past but they have learned that the front desk needs to be staffed by people and if you wander down Queen St, Westpac’s latest branch office is huge with a holiday atmosphere with areas for lounging around and play pens with large lego type helicopter rides for kids and staff hanging around waiting for patronage.

  2. Auckland Airport’s total domestic and international passenger movements have hit 18.1 million in the past 12 months, up nearly two million on the previous corresponding period. The airport ‘s infrastructure is under extreme pressure with many users being caught in vehicle gridlock in the past month.

    I would have thought that Intercity rail to the airport would be a priority but guess not. Instead we will get Intercity Rail at a cost of $3.5 billion into Mt Eden where there is mainly single bungalow housing and not even a decent shopping mall. Gridlock sure does not help productivity.

  3. There is a new industry that just started that should substantially upend all these numbers over the next 5 years but unfortunately that won’t fix the rest of NZ.
    Great blog, look forward to reading next years commentary and have a happy holiday 🙂

  4. Thank you for taking the time to generate debate, especially around the subjects that are not openly debated. Productivity especially along with that bastion of mystery the RBNZ.
    We all learn, even if we all don’t agree.

    Merry Xmas & Happy New year.
    2017 is going to be great.

    • Thanks. Sadly we don’t have a good long run of historical data in NZ. Re their US conclusion, it wouldn’t surprise me if our productivity growth were to pick up again, but there is no obvious reason to expect a break in the decades-long run in which NZ productivity growth has been lower than that of our peer economies.

  5. End of the year and unfortunately we just started getting offside with Israel and possibly also poked Donald Trump’s eye in the process. But I guess we have made friends with most of the Muslim world who buy our halal lamb and joined 14 other security council countries in taking isreal to task.
