Why good news for GDP isn't necessarily good news for the Chancellor

The output gap is a strange and unpredictable beast, writes Nida Broughton.

The Coalition came into Government in 2010 with a plan to repair the public finances and set itself a target to eliminate the structural deficit. The ONS today published figures showing that GDP in the second quarter of this year is even higher than we thought, rising by 0.7 per cent rather than 0.6 per cent. But it isn’t clear if this is good or bad news for the Chancellor’s deficit strategy, because the structural deficit – and therefore the billions of cuts that George Osborne is pencilling in – is determined by small changes in a very slippery measure of the state of the economy: the output gap.

The Government’s structural deficit target is carefully worded to take into account the fact that part of the deficit – the “cyclical” part – will automatically disappear as the economy recovers. From a theoretical point of view, this makes sense: there is little point on focusing efforts on areas of spending that are going to fall anyway. The non-cyclical, “structural” part of the deficit – the part that will remain even when the economy is back on track is surely the part to be concerned about. 

So since 2010, the Office for Budget Responsibility (OBR), whose remit is to report on Government’s performance against its fiscal targets, has set about trying to measure the “output gap” – a measure of how far the economy has to recover.  The output gap is the difference between actual GDP and “potential” GDP. Potential GDP is the level of GDP that the economy could achieve if it were operating at “full capacity”.

But it has become increasingly clear that in practice, the output gap is just too difficult to measure. The OBR’s twice-yearly reports always show a comparison of the OBR’s estimate of the output gap against those made by other forecasters – including banks and independent forecasting houses. This provides a useful sense-check of the OBR’s figures. 

The last OBR report in March, showed, as it always has done, the huge range that different forecasters have come up with in measuring the output gap – ranging from -7.3 per cent to -0.9 per cent for 2013. To put this into context, just a two percentage point difference in the output gap estimate is enough to change the forecast structural deficit in the Government’s target year of 2018 by around £28bn – no small amount when the Government is looking to cut around £33bn after the election.

Earlier this month, the Bank of England, searching for a way to measure the state of the economy as part of its Forward Guidance, decided against the output gap, saying that:

“The output gap is unobservable and difficult to explain, and any estimate would be subject to substantial uncertainty.”

Instead, it plumped for unemployment as a measure. And now even as the economy is showing some signs of life, independent forecasters still can’t agree among themselves on what the positive growth figures mean for the output gap, as shown in the chart below. Of those releasing estimates after July’s surprise good news on growth from the ONS, two thought this meant the economy was now closer to potential. One thought that it was now further away – presumably taking the good news on GDP to be a sign of underlying productivity improvements that mean that the economy’s potential has expanded. And two kept their output gap estimate unchanged.

The question has to be asked: how useful is a public spending target that depends on such an uncertain measure of the economy? Perhaps recognising this, or perhaps because it made for a better statistic, George Osborne omitted to mention the “structural deficit” at all in his last Spending Review speech in June, referring instead to the overall deficit. And even though the structural deficit – on OBR forecasts - is due to go into surplus by 2016-17, George Osborne’s planned cuts stretch out to 2018. So does the Chancellor himself still believe in the usefulness of his target?

Our union backed Brexit, but that doesn't mean scrapping freedom of movement

We can only improve the lives of our members, like those planning stike action at McDonalds, through solidarity.

The campaign to defend and extend free movement – highlighted by the launch of the Labour Campaign for Free Movement this month – is being seen in some circles as a back door strategy to re-run the EU referendum. If that was truly the case, then I don't think Unions like mine (the BFAWU) would be involved, especially as we campaigned to leave the EU ourselves.

In stark contrast to the rhetoric used by many sections of the Leave campaign, our argument wasn’t driven by fear and paranoia about migrant workers. A good number of the BFAWU’s membership is made up of workers not just from the EU, but from all corners of the world. They make a positive contribution to the industry that we represent. These people make a far larger and important contribution to our society and our communities than the wealthy Brexiteers, who sought to do nothing other than de-humanise them, cheered along by a rabid, right-wing press. 

Those who are calling for end to freedom of movement fail to realise that it’s people, rather than land and borders that makes the world we live in. Division works only in the interest of those that want to hold power, control, influence and wealth. Unfortunately, despite a rich history in terms of where division leads us, a good chunk of the UK population still falls for it. We believe that those who live and work here or in other countries should have their skills recognised and enjoy the same rights as those born in that country, including the democratic right to vote. 

Workers born outside of the UK contribute more than £328 million to the UK economy every day. Our NHS depends on their labour in order to keep it running; the leisure and hospitality industries depend on them in order to function; the food industry (including farming to a degree) is often propped up by their work.

The real architects of our misery and hardship reside in Westminster. It is they who introduced legislation designed to allow bosses to act with impunity and pay poverty wages. The only way we can really improve our lives is not as some would have you believe, by blaming other poor workers from other countries, it is through standing together in solidarity. By organising and combining that we become stronger as our fabulous members are showing through their decision to ballot for strike action in McDonalds.

Our members in McDonalds are both born in the UK and outside the UK, and where the bosses have separated groups of workers by pitting certain nationalities against each other, the workers organised have stood together and fought to win change for all, even organising themed social events to welcome each other in the face of the bosses ‘attempts to create divisions in the workplace.

Our union has held the long term view that we should have a planned economy with an ability to own and control the means of production. Our members saw the EU as a gravy train, working in the interests of wealthy elites and industrial scale tax avoidance. They felt that leaving the EU would give the UK the best opportunity to renationalise our key industries and begin a programme of manufacturing on a scale that would allow us to be self-sufficient and independent while enjoying solid trading relationships with other countries. Obviously, a key component in terms of facilitating this is continued freedom of movement.

Many of our members come from communities that voted to leave the EU. They are a reflection of real life that the movers and shakers in both the Leave and Remain campaigns took for granted. We weren’t surprised by the outcome of the EU referendum; after decades of politicians heaping blame on the EU for everything from the shape of fruit to personal hardship, what else could we possibly expect? However, we cannot allow migrant labour to remain as a political football to give succour to the prejudices of the uninformed. Given the same rights and freedoms as UK citizens, foreign workers have the ability to ensure that the UK actually makes a success of Brexit, one that benefits the many, rather than the few.
