Why the job growth forecasts aren’t as rosy as they seem


by Chris Dillow    

Fraser Nelson has chided the media for not giving enough attention to the OBR’s forecast that the private sector will create 1.5 million jobs in the next five years.

If I were he, I wouldn’t crow about this. My chart, taken from my day job, shows why.

  It shows annual labour productivity growth – defined as GDP divided by employment – over five year periods, along with the growth implied by the OBR forecasts for GDP (pdf) and employment (pdf).

It’s clear from this that the OBR’s forecast for lots of job creation implies low productivity growth.

Stunningly low, in fact.

The OBR expects productivity on this measure to grow by just 1.8% a year over the next five years. This is less than it grew in the eight years to March 1979 (2.1% pa).

In other words, a massive switch in employment from the “inefficient” public sector to the “dynamic” private sector will be associated with lower productivity growth than we saw at a time when trades unions were, allegedly, holding the country to ransom.

If the OBR is correct – and of course it probably won't be – then Tories’ basic views about the economy are plain wrong. Shrinking the state and weakening trades unions do not increase productivity growth.
As I say, Fraser shouldn’t draw too much attention to the OBR forecast.

Now, you might object here that my measure of productivity is biased. My employment measure – actually, the OBR’s – conflates full- and part-time jobs. This means that if the share of part-time employment rises, productivity will fall on my measure.

This, though, is little help to Fraser – unless he wants to draw attention to the fact that many of the private sector jobs that‘ll be created will only be part-time ones.
(The OBR, AFAIK, does not give separate forecasts for full and part-time employment).

Interesting how productivity declined consistently from the moment Labour came to office.

Interesting that your forecast increase to 2014 exactly mirrors the decline from 2014.

I was going to ask the same question.

What on earth happened from 97-08, leaving the crash aside?

@ 1 and 2

Oh dear. If you actually look at the graph, I think you’ll find that productivity grew by an average of around 2% during Labour’s reign.

@3

Oh dear, if you actually look at the graph you will see that it is a rolling 5 year average.

So the 97 reading – around 2.4% – would be the final five years of Tory govt.

Downhill from there…

If you are conflating full and part-time jobs would it not make more sense to use productivity in terms of GDP per hour worked? The UK does slightly better on this measure compared to the per worker basis. Anyway they may be underestimating future productivity growth. Until the recession the UK had the fastest growing productivity in the G7- 1991-2007 40 percentage points on the per worker measure. On the per hour measure the growth was 44 percentage points 1991-2009. This was also the fastest G7 growth. Other than the coalition immigration policies there is no reason why the former productivity growth trajectory can’t be continued.

Moreover, what is probably implied in the OBR employment forecasts but not explicitly stated is the effect of the depreciated real effective exchange rate on unit labour costs. Without suffering a nominal wage cut British workers are working for a lower real wage, they just do not realise it.

@ 4

Could you kindly point out that bit of the graph that shows a decline in productivity? Hint: a ‘decline’ means negative growth. Y’know, a minus number. I must be looking straight past it…

Oh for goodness sake, a decline in the rate of growth…

Either way, the Lab average is well below 2.

Sorry you missed the “5 year annualized” bit.

8. Chaise Guevara

@ 7

I did miss the annualized bit. Sorry you missed the “a rise isn’t a decline” bit.

A decline in productivity GROWTH, sure. But that’s a different kettle of fish and a suddenly distant set of goalposts, isn’t it?

I never used the word “decline” BTW, that was #1.

Distant but important, given the power of compounding.

10. Chaise Guevara

“I never used the word “decline” BTW, that was #1.”

I know, but you said you were going to ask the same question so I replied to both of you. You’ve actually sort of picked up astateofdenmark’s error rather than making it yourself.

“Distant but important, given the power of compounding.”

Fair enough. I don’t know the specific causes, but the decline doesn’t fit onto the years of Labour government as tightly as you’re making out. Growth stops rising in ’96; until ’99/’00 we’re still talking about an assessed period that mostly happened under a Tory administration. Labour probably do have something to do with it, though, most likely because they’re focused on social justice rather than economic efficiency.

11. Chaise Guevara

*Oh, one other thing. The Tories give tax breaks to firms and rich individuals, with short-term benefits. Labour puts money into education and so forth, with long-term benefits. You shouldn’t actually expect to see all the benefits of a Labour administration for a decade or so.

12. margin4error

1 – I don’t suppose the media put much store in what the OBR has been told to say by George Osborne. (I know too many Treasury officials to have any faith in the OBR and to see it as anything but damaging that actual independent experts are leaving the Treasury as they feel as though their work is being degraded)

2 – for those wondering about productivity falling under Labour – this tends to happen when employement rises. After all, there tend not to be large number of highly skilled, well educated unemployed people to take up new jobs that are more productive than the average across the economy.
