The most important paragraph in the IMF World Economic Outlook

68 words of wonkishness.

The IMF's World Economic Outlook (pdf) – a 230-page tome detailing predictions on nearly every aspect of the world's economy collated by the international organisation – always gets attention for the calls it makes.

The October edition downgrades expected global growth for 2013 from 3.9 per cent to 3.6 per cent, and also cuts predictions for China (down to 8.2 per cent for 2013), the US (expected to grow by 2.1 per cent in 2013, down from 2.3 per cent in July's prediction) and the UK (now expected to grow by just 1.1 per cent next year, and to contract by 0.2 per cent this year).

But the predictions are not the most important passages in this edition of the Outlook. Those are found in a short box-out titled Are We Underestimating Short-Term Fiscal Multipliers?

The fisc§al multiplier is the effect government spending has on GDP. Money spent by the government doesn't disappear – it is respent, again and again. If a teacher gets a pay rise, their consumption is likely to rise in line with it; if all teachers get pay rises, that increase in consumption may be enough to affect the aggregate demand in the economy. In an economy which isn't being stretched to its limits – that is, one without full employment, or serious capital equipment shortages – that increase in aggregate demand will result in an increase in GDP.

The existence of the fiscal multiplier is a matter of fact, but the magnitude of it is contested. And that's where the IMF enters the scene, on page 42:

The main finding, based on data for 28 economies, is that the multipliers used in generating growth forecasts have been systematically too low since the start of the Great Recession, by 0.4 to 1.2, depending on the forecast source and the specifics of the estimation approach. Informal evidence suggests that the multipliers implicitly used to generate these forecasts are about 0.5. So actual multipliers may be higher, in the range of 0.9 to 1.7.

Emphasis mine. When deciding how much to spend, governments have been assuming that every pound they spend increases GDP by 50p – but it may increase it by as much as £1.70.

The reason this is so very important is that fiscal multiplier is usually appealed to not when deciding how much to spend, but how much to not spend. When governments are planning austerity packages, they have to be wary of the fact that large cuts to government spending will inevitably cause a decrease in output, and so they either have to be prepared to take that hit, or come up with a reason why slashing spending will cause an increase in output through some other mechanism.

That is easy enough to do if you are trying to account for a fiscal multiplier of 0.5: you can make the arguments, which Osborne and Cameron rehearsed repeatedly, that the public sector is crowding out the private; that the government spending which is being cut is particularly inefficient; or that the confidence fairies will reward your thriftiness with growth.

When there is the chance that the fiscal multiplier is three times that, austerity becomes much more likely to involve damaging drops in output.

There was once a time when the government pegged its credibility to that of the IMF – back when George Osborne was proud about Britain's credit ratings, and the international community was behind his plans. Those days are gone, and have been since Christine Lagarde made her own attack on austerity. But the economists at the treasury may be more inclined to listen to the wonkish findings of the World Outlook than the political interventions of the fund's leader. We can only hope they are prompted to re-do the sums.

Is Scottish Labour on the way back, or heading for civil war?

There are signs of life, but also recriminations.

The extraordinary rise of the Scottish Tories and the collapse in SNP seat numbers grabbed most of the headlines in the recent general election. Less remarked on was the sudden, unexpected exhalation of air that came from what was thought to be the corpse of Scottish Labour.

In 2015, Labour lost 40 of its 41 Scottish seats as the SNP rocketed from six to 56, was wiped out in its Glaswegian heartlands, and looked to have ceded its place as the choice of centre-left voters – perhaps permanently – to the Nationalists. But while the electorate’s convulsion in June against the SNP’s insistence on a second independence referendum most benefited Ruth Davidson, it also served to reanimate Labour.

The six seats grabbed back (making a total of seven) included three in the West of Scotland, proving that the Nat stranglehold on Labour’s territory was not quite as secure as it had seemed. There is, it appears, life in the old dog yet.

Not only that, but the surprise success of Jeremy Corbyn across the UK has stiffened Labour’s spine when it comes to insisting that it, and not the SNP, is the rightful home of Scotland’s socialists.

Corbyn was largely kept south of the border during the election campaign – Kezia Dugdale, the leader at Holyrood, had supported Owen Smith’s leadership challenge. But in August, Corbyn will embark on a five-day tour of marginal SNP constituencies that Labour could potentially take back at the next election. The party has set a target of reclaiming 18 Scottish seats as part of the 64 it needs across Britain to win a majority at Westminster. The trip will focus on traditional areas such as Glasgow and Lanarkshire, where tiny swings would return seats to the People’s Party. Dugdale is no doubt hoping for some reflected glory.

Corbyn will present himself as the authentically left-wing choice, a leader who will increase public spending and invest in public services compared to the austerity of the Tories and the timidity of the SNP. “Labour remains on an election footing as a government-in-waiting, ready to end failed austerity and ensure that Scotland has the resources it needs to provide the public services its people deserve,” he said. “Unlike the SNP and the Tories, Labour will transform our economy through investment, insisting that the true wealth creators - that means all of us – benefit from it.”

The SNP has benefited in recent years from the feeling among many north of the border that Labour and the Tories were committed to differing shades of a similar economic programme, that was starving public services of cash and that paid little attention to Scottish desires or needs. But as the Nats’ spell in government in Edinburgh has worn on, first under Alex Salmond and now Nicola Sturgeon, with little being done to tackle the nation’s social problems, patience has started to run out.

Dugdale said yesterday that she “looked forward to joining Jeremy in August as we take our message to the people of Scotland”. That’s not a sentiment we would have heard from her before June. But it does raise the future spectacle of Davidson’s Tories battling for the centre and centre-right vote and Labour gunning for the left. The SNP, which has tried to be all things to all people, will have to make a choice – boasting that it is “Scotland’s Party” is unlikely to be enough.

The 20th anniversary of the referendum that delivered the Scottish Parliament is almost upon us. Then, Scottish Labour provided the UK and the Westminster government with figures of the stature of Gordon Brown, Robin Cook, Donald Dewar and George Robertson. That was a long time ago, and the decline in quality of Labour’s representatives both in London and Edinburgh since has been marked. The SNP’s decade of success has attracted much of the brightest new talent through its doors. Young Scots still seem to be set on the idea of independence. Labour has a credibility problem that won’t be easily shaken off.

But still, the body has twitched – perhaps it’s even sitting up. Is Scottish Labour on the way back? If so, is that down to the SNP’s declining popularity or to Corbyn’s appeal? And could Dugdale be a convincing frontwoman for a genuinely left-wing agenda?

There may be trouble ahead. Yesterday, the Scottish Labour Campaign for Socialism – whose convener, Neil Findlay MSP, ran Corbyn’s leadership campaign in Scotland – accused Dugdale of “holding Corbyn back” in June. A spokesperson for the group said: “While it’s great we won some seats back, it’s clear that the campaign here failed to deliver. While elsewhere we've seen people being enthused by ‘for the many, not the few’ we concentrated on the dispiriting visionless ‘send Nicola a message’ – and paid a price for that, coming third in votes and seats for the first time in a century. In Scotland we looked more like [former Scottish leader] Jim Murphy’s Labour Party than Jeremy Corbyn’s – and that isn’t a good look.”

While the group insists this isn’t intended as a challenge to Dugdale, that might change if Corbyn receives a rapturous reception in August. We’ll learn then whether Scotland is falling for the high-tax, high-spending pitch that seems to be working so well elsewhere, and whether Scottish Labour has jerked back to life only to find itself staring down the barrel of a civil war.
