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?

The economics of outrage: Why you haven't seen the end of Katie Hopkins

Her distasteful tweet may have cost her a job at LBC, but this isn't the last we've seen of Britain's biggest troll. 

Another atrocity, other surge of grief and fear, and there like clockwork was the UK’s biggest troll. Hours after the explosion at the Manchester Arena that killed 22 mostly young and female concert goers, Katie Hopkins weighed in with a very on-brand tweet calling for a “final solution” to the complex issue of terrorism.

She quickly deleted it, replacing the offending phrase with the words “true solution”, but did not tone down the essentially fascist message. Few thought it had been an innocent mistake on the part of someone unaware of the historical connotations of those two words.  And no matter how many urged their fellow web users not to give Hopkins the attention she craved, it still sparked angry tweets, condemnatory news articles and even reports to the police.

Hopkins has lost her presenting job at LBC radio, but she is yet to lose her column at Mail Online, and it’s quite likely she won’t.

Mail Online and its print counterpart The Daily Mail have regularly shown they are prepared to go down the deliberately divisive path Hopkins was signposting. But even if the site's managing editor Martin Clarke was secretly a liberal sandal-wearer, there are also very good economic reasons for Mail Online to stick with her. The extreme and outrageous is great at gaining attention, and attention is what makes money for Mail Online.

It is ironic that Hopkins’s career was initially helped by TV’s attempts to provide balance. Producers could rely on her to provide a counterweight to even the most committed and rational bleeding-heart liberal.

As Patrick Smith, a former media specialist who is currently a senior reporter at BuzzFeed News points out: “It’s very difficult for producers who are legally bound to be balanced, they will sometimes literally have lawyers in the room.”

“That in a way is why some people who are skirting very close or beyond the bounds of taste and decency get on air.”

But while TV may have made Hopkins, it is online where her extreme views perform best.  As digital publishers have learned, the best way to get the shares, clicks and page views that make them money is to provoke an emotional response. And there are few things as good at provoking an emotional response as extreme and outrageous political views.

And in many ways it doesn’t matter whether that response is negative or positive. Those who complain about what Hopkins says are also the ones who draw attention to it – many will read what she writes in order to know exactly why they should hate her.

Of course using outrageous views as a sales tactic is not confined to the web – The Daily Mail prints columns by Sarah Vine for a reason - but the risks of pushing the boundaries of taste and decency are greater in a linear, analogue world. Cancelling a newspaper subscription or changing radio station is a simpler and often longer-lasting act than pledging to never click on a tempting link on Twitter or Facebook. LBC may have had far more to lose from sticking with Hopkins than Mail Online does, and much less to gain. Someone prepared to say what Hopkins says will not be out of work for long.
