The IMF changing its stance leaves the OBR and Treasury isolated

The number of people who think that this recession was unpredictable is shrinking by the day, writes NIESR's Jonathan Portes.

The IMF's reassessment of the "fiscal multiplier" has sparked off multiple reactions in the economics blogosphere both in the US and UK. My initial reaction is here. Meanwhile, Chris Giles at the FT has weighed in (£), attempting to demonstrate that the IMF's analysis is not robust. I'd like to step back a bit now from the IMF piece (I'll return to it later) and explain why this matters.

As I discuss here, in mid-2010 the international economic policymaking community, led by the IMF, and very much influenced by the new Coalition governnment in the UK, executed what became known as the "pivot" to fiscal consolidation. Pretty much everyone agreed that it was necessary to reduce budget deficits; the question was how quickly, and what the damage, if any, to growth would be. As a reminder for those new to this debate, the "multiplier" measures this: it is the reduction in output resulting from a given reduction in the budget deficit (so if the multiplier is 1, then a reduction in the budget deficit of 1 per cent of GDP reduces output by 1 per cent). On this question, broadly, there were three camps.

First, a small group of economists argued both on theoretical and empirical grounds that fiscal consolidation wouldn't reduce growth at all – indeed it might even enhance growth (so the multiplier would be zero or positive). The doctrine of "expansionary fiscal contraction" argued that tightening fiscal policy could, through exchange rate and confidence effects, actually increase demand and growth; a paper (£) by Alesina and Ardagna was particularly influential in this respect. While this was always a minority view among empirical macroeconomists, this research was quickly picked up on by those politicians who wanted aggressive deficit cuts, in both the UK and EU. For example, Matthew Hancock MP, formerly George Osborne's Chief of Staff (and now Minister for Skills), claimed:

I discovered that research into dozens of past fiscal tightenings shows that, more often than not, growth doesn't fall but accelerates.

Somewhat more tentatively, the UK Treasury argued (although I doubt any Treasury official believed this for a moment) in the 2010 Emergency Budget that: 

[The wider effects of fiscal consolidation] will tend to boost demand growth, could improve the underlying performance of the economy and could even be sufficiently strong to outweigh the negative effects.

So while this view was never very credible economically, it certainly influenced policy.

The second view was that taken by mainstream economic modellers and forecasters, including most importantly the IMF, but also the UK Office for Budget Responsibility, the Bank of England and indeed us here at NIESR. This was that the negative impact of fiscal consolidation on growth would be significant, but not disastrous. The IMF never believed the Alesina and Ardegna results; in October 2010 the Fund concluded that:

Fiscal consolidation typically lowers growth in the short term. Using a new data set, we find that after two years, a budget deficit cut of 1 percent of GDP tends to lower output by about 0.5 per cent and raise the unemployment rate by ⅓ percentage point.

These estimates were based on historical experience over the last three decades; using similar data, NIESR's model incorporate similar estimates. And when estimating the impact of the UK fiscal consolidation programme announced in June 2010, the OBR also used very similar estimates. This is hardly surprising: as Duncan Weldon points out in a neat bit of detective work, the OBR's multiplier estimates are based primarily on one IMF paper, as well as two papers from NIESR researchers. 

There was, however, a third view. This  was advanced most strongly by Paul Krugman and Brad Delong in the US, and here by Martin Wolf (in the columns of the FT) and Simon Wren-Lewis; it was that the experience of the last three decades (except, perhaps, in Japan) was not relevant to that of a world where monetary policy was limited by the zero lower bound on interest rates (or, for those like Scott Sumner who think that monetary policy could have been even more aggressive, by political or institutional constraints).  In such a world, multipliers would be significantly higher, and almost certainly greater than one.   Simon explains why here, concluding perceptively that this may be "an occasion where thinking about macroeconomic theory can be rather more useful than naively following the evidence of the past."  Meanwhile, Antonia Fatas and Ilian Mihov argued on empirical grounds that the Fund and others were consistently underestimating the size of the multiplier, as they explain here

So what then is the significance of the IMF analysis published this week? For reference, I will repeat the key paragraph:

In line with these assumptions, earlier analysis by the IMF staff suggests that, on average, fiscal multipliers were near 0.5 in advanced economies during the three decades leading up to 2009. If the multipliers underlying the growth forecasts were about 0.5, as this informal evidence suggests, our results indicate that multipliers have actually been in the 0.9 to 1.7 range since the Great Recession. This finding is consistent with research suggesting that in today’s environment of substantial economic slack, monetary policy constrained by the zero lower bound, and synchronized fiscal adjustment across numerous economies, multipliers may be well above 1.

So, in contrast to the Fund's 2010 view, multipliers are much larger than 0.5 – large enough to have a very substantial, and negative, impact on growth.  

Now, the IMF analysis, in isolation, is clearly not definitive "proof" that multipliers are now 0.9 to 1.7 – and even if it was, that would not "prove" anything about multipliers in a specific country. I won't attempt to arbitrate between the Fund and Chris Giles on econometrics, except to say that his detailed analysis (£) confirms my view, which he also reports, that cross-country regressions are typically not very robust, and in general can be used to make pretty much any argument you like (indeed, this is precisely the same reason I never believed the Alesina and Ardegna result either). So while I think the new Fund analysis does broadly support the view that in general terms one of the reasons the Fund's forecasts (in common with pretty much everyone else's) have been too optimistic is that they underestimated the negative impact of fiscal consolidation, I wouldn't place much weight on them in isolation. 

But what is clear – particularly in the last sentence I quote above – is that the Fund has now accepted that the balance of the argument, both theoretical and empirical, has tilted decisively in favour of the third group of economists above. It's not just about one set of regressions; these are simply a further piece of supportive and confirmatory evidence supporting those of us who argued that aggressive fiscal consolidation was an unnecessary and dangerous gamble, with very serious downsides. The Fund is now squarely in this camp. This is a major intellectual shift – as Isabella Kaminska writes, no wonder Paul Krugman is feeling "smuggish". But leaving aside the economists' debate, how should this affect policy? In the UK, I can think of two key implications:

  • The first relates to the current debate about how large the UK "output gap" is, and hence how much scope there is for expansionary policy (both fiscal and monetary). The UK economy has essentially seen zero growth for the past two years.  Some analysts – Chris Giles being the most credible, but the OBR has also taken this line – have argued that given the sort of multipliers assumed by the OBR and IMF, fiscal consolidation can't explain much of this growth shortfall, so it must be something else: supply side weakness, commodity prices, and so on, meaning that changing fiscal policy might not do much good.  If, however, multipliers were in fact much higher, then fiscal consolidation is indeed the main reason for weak growth; and correspondingly, the scope for boosting growth through expansionary policy is much greater;
  • The second relates very specifically to the OBR. As Duncan pointed out, the OBR's excessively optimistic forecasts were explicitly based on multipliers derived from IMF research. The IMF has now explicitly changed its mind; the OBR's position is no longer tenable. If it wants to retain its credibility as an economic forecaster independent of government, it needs to examine its assumptions and methodology, both retrospectively and prospectively, on the impact of fiscal consolidation on growth. The December OBR forecast should include at a minimum both a reassessment of its forecast record, in the light of the Fund's change of view, and an assessment going forward of the impact of different multiplier assumptions on growth. 

Arguably, however, far more important than the UK debate- and far more central to the concerns of the IMF – are the implication for the eurozone, and in particular for the current adjustment programmes in Greece, Spain, Italy, Ireland and Portugal. Several months ago, I argued:

Clearly long-run solvency is also essential. But, in Spain and Italy, trying to hit arbitrary short-run deficit targets, as proposed by the European Commission, is likely if anything to be counterproductive to the objective of long-run sustainability. Spain’s long-term fiscal position, for example, is relatively strong; what it needs to ensure that remains the case is decent levels of economic growth, and what it needs for that is structural reform, especially labour market reform. Both politically and economically, such reforms will be both less painful and more effective if fiscal consolidation is much slower, as I argue here. These arguments on timing hold good even if multipliers and hysteresis effects are relatively small; if such effects are large – and there is every reason to believe that in European labour markets hysteresis effects are of profound macroeconomic importance – then they are even more compelling.

The IMF clearly now agrees with this, as Christine Lagarde has made clear in the case of Greece. They need now to point out to the European Commission and the German government as forcefully as possible that if they do not belatedly come to their senses, they will run the economies of Southern Europe – and possibly the euro itself – into the ground on the basis of an economic analysis that has now been discredited both theoretically and empirically.

Finally, what about us at NIESR? Well, we did produce this, examining why the multiplier might be larger in current circumstances, and examining the implications; precisely what the OBR should have done. But, more broadly, when presenting NIESR forecasts in 2011, I was frequently asked why we were rather pessimistic relative to most other forecasters, and certainly the OBR.  My response was often that what I worried about most was not that our model's predictions looked rather gloomy; it was that the economists I took most seriously – those listed above, who don't use quantitative models – thought our model was far too optimistic. And so it proved.

What's to be done about racial inequality?

David Cameron's words on equal opportunities are to be welcomed - now for some action, says Sunder Katwala.

David Cameron made the strongest, clearest and most high profile statement about ethnic inequalities and the need to tackle discrimination ever yet offered by a British Prime Minister in his leader’s speech to the Conservative Party conference in Manchester.
“Picture this. You’ve graduated with a good degree. You send out your CV far and wide. But you get rejection after rejection. What’s wrong? It’s not the qualifications or the previous experience. It’s just two words at the top: first name, surname. Do you know that in our country today: even if they have exactly the same qualifications, people with white-sounding names are nearly twice as likely to get call backs for jobs than people with ethnic-sounding names? … That, in 21st century Britain, is disgraceful. We can talk all we want about opportunity, but it’s meaningless unless people are really judged equally”, said Cameron.
While the proof of the pudding will be in the eating, this was a powerfully argued Prime Ministerial intervention – and a particularly well-timed one, for three reasons.

Firstly, the Prime Minister was able to root his case in an all-but-universally accepted appeal for equal opportunities. It will always prove more difficult in practice to put political energy and resources behind efforts to remedy discrimination against a minority of the population unless a convincing fairness case is made that values cherished across our whole society are at stake. Cameron’s argument, that any party which tells itself that it is the party of the ‘fair chance’ and ‘the equal shot’ must have a response when there is such clear evidence of discrimination, should prove persuasive to a Conservative Party that has not seen race inequalities as its natural territory. Cameron argued that the same principles should animate responses to discrimination when it comes to race, gender and social class. Put like that, wanting job interviews to be fair – by eradicating conscious and unconscious patterns of bias wherever possible – would strike most Britons as offering as clear a case of the values of fair play as wanting the best baker to win the Great British Bake-Off on television.
Secondly, Cameron’s intervention comes at a potential "tipping point" moment for fair opportunities across ethnic groups. Traditionally, ethnic discrimination has been discussed primarily through the lens of its impact on the most marginalised. Certainly, persistent gaps in the criminal justice system, mental health provision and unemployment rates remain stark for some minority groups. What has been less noticed is the emergence of a much more complex pattern of opportunity and disadvantage – not least as a consequence of significant ethnic minority progress.

Most strikingly of all, in educational outcomes, historic attainment gaps between ethnic minorities and their white British peers have disappeared over the last decade. In the aggregate, ethnic minorities get better GCSE results on average. Ethnic minority Britons are more likely, not less likely, to be university graduates than their fellow citizens. 

As a result of that progress, Cameron’s intervention comes at a moment of significant potential – but significant risk too. Britain’s ethnic minorities are the youngest and fastest-growing sections of British society. If that educational progress translates into economic success, it will make a significant contribution to the "Great British Take-Off" that the Prime Minister envisions. But if that does not happen, with educational convergence combined with current ‘ethnic penalties’ in employment and income persisting, then that potential could well curdle into frustration that the British promise of equal opportunities is not being kept.  Cameron also mirrored his own language in committing himself to both a ‘fight against extremism’ and a ‘fight against discrimination’: while those are distinct challenges and causes, actively pursuing both tracks simultaneously has the potential, at least, depolarise some debates about responses to extremism  - and so to help deepen the broad social coalitions we need for a more cohesive society too.

Thirdly, Cameron’s challenge could mark an important deepening in the political competition between the major parties on race issues. Many have been struck by the increase in political attention on the centre-right to race issues over the last five to ten years. The focus has been on the politics of representation. By increasing the number of non-white Conservative MPs from two to seventeen since 2005, Cameron has sent a powerful signal that Labour’s traditional claim to be ‘the party of ethnic minorities’ would now be contested. Cameron was again able to celebrate in Manchester several ways in which his Cabinet and Parliamentary benches demonstrate many successful journeys of migrant and minority integration in British society. That might perhaps help to ease the fears, about integration being impossible in an era of higher immigration, which the Home Secretary had articulated the previous day.

So symbolism can matter. But facial diversity is not enough. The politics of ethnic minority opportunity needs to be about more than visits to gurdwaras, diversity nights at the party conference fringes and unveiling statues of Mahatma Gandhi in Parliament Square. Jeremy Corbyn’s first speech as Labour leader did include one brief celebratory reference to Britain’s ethnic diversity – “as I travelled the country during the leadership campaign it was wonderful to see the diversity of all the people in our country” – and to Labour bringing in more black, Asian and ethnic minority members - but it did not include any substantial content on discrimination. Tim Farron acknowledged during his leadership campaign that the Liberal Democrats have struggled to get to the starting-line on race and diversity at all. The opposition parties too will no doubt now be challenged to match not just the Prime Minister’s rhetorical commitment to challenging inequalities but also to propose how it could be done in practice.

Non-white Britons expect substance, not just symbolism from all of the parties on race inequalites.  Survation’s large survey of ethnic minority voters for British Future showed the Conservatives winning more ethnic minority support than ever before – but just 29 per cent of non-white respondents were confident that the Conservatives are committed to treating people of every ethnic background equally, while 54 per cent said this of Labour. Respondents were twice as likely to say that the Conservatives needto do more to reach out – and the Prime Minister would seem to be committed to showing that he has got that message.  Moreover, there is evidence that ethnic inclusion could be important in broadening a party’s appeal to other younger, urban and more liberal white voters too – which is why it made sense for this issue to form part of a broader attempt by David Cameron to colonise the broad centre of British politics in his Manchester speech.

But the case for caution is that there has been limited policy attention to ethnic inequalities under the last two governments. Restaurateur Iqbal Wahhab decided to give up his role chairing an ethnic minority taskforce for successive governments, unconvinced there was a political commitment to do much more than convene a talking shop. Lib Dem equalities minister Lynne Featherstone did push the CV discrimination issue – but many Conservatives were sceptical. Cameron’s new commitment may face similar challenges from those whose instinct is to worry that more attention to discrimination or bias in the jobs market will mean more red tape for business.

Labour had a separate race inequalities manifesto in 2015, outside of its main election manifesto, while the Conservative manifesto did not contain significant commitments to racial inequality. The mid-campaign launch in Croydon of a series of race equality pledges showed an increasing awareness of the growing importance of ethnic minority votes - though the fact that they all involved aiming for increases of 20 per cent by 2020 gave them a slightly back-of-the-envelope feel. 

Prime Ministerial commitments have an important agenda-setting function. A generation ago the Stephen Lawrence case opened the eyes of middle England to racist violence and police failures, particularly through the Daily Mail’s persistent challenging of those injustices. A Conservative Prime Minister’s words could similarly make a big difference in the mainstreaming of the issue of inequalities of opportunity. What action should follow words? Between now and next year’s party conference season, that must will now be the test for this Conservative government – and for their political opponents too.
