UK monetary policy: you cannot be serious?

Nothing shocks me in the area of fiscal policy anymore, but I do have some faith that monetary policy makers know what they are doing. While fiscal policy makers in the US, UK and the EZ did precisely the wrong thing consistently from 2010, monetary policy makers rightly pulled out all the stops, and my main quarrel was that in the UK and EZ they pretended QE was an instrument with the same order of reliability as interest rates. Instead they should have told fiscal policy makers that they could no longer do their jobs efficiently because interest rates had hit their lower bound.

However, there are occasional aberrations. EZ interest rates went up in 2011 rather than down and the MPC almost did the same. (Let’s not mention Sweden.) And then, last month, three members of the MPC voted to raise interest rates. After I had had my John McEnroe moment, I quickly realised that these three members were making exactly the same mistake as a different three made in 2011. Only this time they had less excuse.

Back in 2011, inflation was between 4% and 5% but the UK was still in deep recession. Inflation was high because of austerity (an increase in VAT), higher energy prices and maybe the lagged effects of an earlier depreciation. In 2017 inflation is high because of the Brexit depreciation, yet the real economy looks very weak as consumers start to pull back spending. In essence the situation is identical: inflation is high because of one-off factors, and because the real economy is weak inflation will come back down of its own accord. There is no point making the real economy even weaker by raising interest rates.

The only thing you might worry about in these circumstances is that inflation might be more persistent than you thought because nominal wages start to rise as workers try and avoid falls in real wages. That didn’t happen in 2011 even though inflation reached 5%, and inflation did come quickly back to near target within a year. An increase in interest rates would have achieved nothing except make the recession worse.

Exactly the same applies now, with the only difference being inflation is still less than 3%. We can be sure of this by looking at what is happening to nominal wages. UK nominal wages have increased in the four months of 2017 by less than 2% compared to a year earlier, which represents a distinctly lower rate of growth than in the second half of 2016. A relative price change, like a depreciation, can only shift inflation permanently higher if wage inflation starts rising. Right now it is falling.

When I recently wrote about increasing the inflation target, I knew I would get at least one comment saying wouldn’t this reduce real wages even further. As I always do, I explained that raising the inflation target should raise the rate of increase of all nominal quantities by the same amount, which is what economists mean by inflation. But it seems the same basic point has to be made to these three members of the MPC too: inflation is not just the rate of change of the consumer price index.

The weakness of real wages in the face of rising inflation (and remember this increase in inflation was predictable the moment Brexit happened) also tells us something important about the UK labour market. Here is the Resolution Foundation’s underemployment measure, based on work by Bell and Blanchflower. It shows the index still above its level in the first half of the 2000s. 


But perhaps more importantly, the weakness of nominal wages suggests that the NAIRU may have decreased since then. A good rule for monetary policymakers right now is to only think about raising interest rates when nominal wage inflation starts rising by more than 2% above underlying labour productivity growth. 

Postscript 22/6/17

The day this post was published a speech from MPC member Andy Haldane was also published. Haldane did not vote for higher interest rates in May. It is a speech of two halves. The first presents a detailed and analytical discussion of the changing nature of the UK labour market, and his conclusion is that the NAIRU may well have declined as a result. He therefore provides solid evidence for the conjecture in my last paragraph. 

However the second half of the speech is in complete contrast. It involves a kind of unstructured shopping list of pros and cons for raising rates, full of references to things like 'political uncertainty' and equity markets and 'inflation narratives'. As a result of that, he favours raising rates earlier than markets expect. Sterling rose on publication of the speech. (If nothing else, sterling's reaction to first Carney's speech and then this has been a nice vindication of uncovered interest parity (UIP) theory.)

I think there is another way of describing this speech of two halves. The first involves a careful analysis of a key driver of the inflationary process (and finds a strong explanation of why wage inflation is currently weak). The second is unstructured list making, with a decision based on some unexplained intuitive process. I may be a little harsh, but it looks to me like the best and worst of monetary policy making.

Austerity will only end when our leaders start being honest

Austerity was the underlying motivation for starting this blog. Sometimes I think everything that I, Paul Krugman and many others have written over the last six or more years has fallen on deaf ears. Take two recent pieces of evidence: this FT article by Nicholas Macpherson, ex permanent secretary at the Treasury, and this interview of the Chancellor by Andrew Marr.

In talking about Osborne’s fiscal consolidation that began in 2010, Macpherson says: “With hindsight, there was a case for going further faster.” His rationale is that the public like a dose of austerity, but tire after a time. At no point does he mention the economy (a recovery that stalled from 2010 to 2013, and then only started growing at trend thereafter), or monetary policy (interest rates were stuck at their lower bound). His desire for a shorter, sharper fiscal shock would have almost certainly produced a second recession.

I calculated that the fiscal consolidation that did take place cost the average household at least £4,000 in lost resources. This is based on OBR numbers, and assumes (as the OBR does) that the economy recovers quickly from any fiscal consolidation. This latter assumption looks very shaky indeed. Once you stop making it, the costs of austerity become horribly large. Not a word about this from Macpherson, which allows him to make the ridiculous argument that we should have had a shorter sharper consolidation.

One of the other ridiculous things Macpherson says is that, from 2010 to 2016, the UK did not even experience austerity. He justifies this because the debt to GDP ratio over this period rose. I’ve heard similar things in comments on my blog, presumably because of what Conservative politicians or their apologists say in the press. The statement confuses levels with rates of change, whether you are talking about the impact on the economy or on individuals. This is first year undergraduate stuff.

Philip Hammond said in his interview that a deficit of 2.5% is not sustainable. The normal definition of sustainability is a deficit that keeps the debt to GDP ratio constant. The current debt to GDP ratio is 86.5%. To work out roughly what the sustainable deficit is, divide the debt level by 100 and multiply that by the expected growth rate of nominal GDP. That means that today a deficit of 2.5% of GDP would be sustainable as long as nominal GDP grew at about 3%. So his statement that a deficit of 2.5% is not sustainable simply looks wrong.

You could rationalise this by saying that he believes our current debt to GDP level is not sustainable, and that therefore he wants to reduce it, but if that is what he means he should say so. Instead it seems that he wants to pretend that the government is like a household, and so therefore there is some reason why a deficit of zero is desirable. Of course Hammond does not mention interest rates either. And he knows that, in an interview like this, he can get away with anything involving economics or numbers.

Austerity has been supposedly dying since after the Brexit vote, but that just reflects misleading or dishonest reporting. As Torsten Bell says, for most people austerity means cuts to public spending, and for public sector workers and those on low incomes there is more austerity to come. Hammond also said Labour’s proposed fiscal policy would be “catastrophic for the country”. I suspect this kind of nonsense hyperbole, frequently invoked by the right wing press, has now become counter-productive. In reality at the heart of Labour’s fiscal policy is a fiscal rule which takes the government’s role in the economy seriously, rather than reduce it to the budget of a Swabian housewife. I cannot wait for the day that becomes the UK government’s fiscal rule, and we can move discussion of UK fiscal policy away from numbers 'not adding up' and back into the 21st century.

Raising the inflation target

The argument for a higher inflation target is straightforward, once you understand two things. First the most effective and reliable monetary policy instrument is to influence the real interest rate in the economy, which is the nominal interest rate less expected inflation. Second nominal short term interest rates have a floor near zero (the Zero Lower Bound, or ZLB). Combine the two and you have a severe problem in a recession, because to combat the recession real interest rates need to move into negative territory, and how far they can go into that territory is limited by the ZLB. That means monetary policy alone may be unable to get us out of a recession.

Raising the inflation target reduces the likelihood that interest rates will hit the ZLB. To see why, note first that the long run (economists often say ‘equilibrium’ or ‘natural’) real interest rate is positive. Let’s say it is 2%. If the inflation target is 2%, and the ZLB is 0%, that would mean that in normal times the average nominal interest rate is 4% (2% inflation target + 2% to get to a 2% real interest rate). That means nominal interest rates can be cut by a maximum of 4% if the economy falters. That may be enough for a mild downturn, but as we saw in 2008 it is not enough for a major recession. However if the inflation target was 4%, nominal rates would now be able to fall by a maximum of 6%. That is probably enough to combat all but the worst kind of recession.

Why are many economists currently arguing that we should raise the inflation target from 2% to 4%? One of the reasons is that we now believe the long run real interest rate is currently lower than it was when the 2% target was first chosen. (This is sometimes referred to as secular stagnation.) If you go through the arithmetic above, you can see why a lower long run real interest rate will make the ZLB problem worse. The argument is that we now need to raise the inflation target to make sure we hit the ZLB less often in the future.

This issue moved from an academic discussion to a real possibility in the US a few days ago. When Fed Chair Janet Yellen had been asked about raising the inflation target in the past, she has tended to dismiss the idea. However she now says that it is something that the Fed will review in the future, and that it is one of the most important questions facing central bankers today.

This will undoubtedly give new impetus to the debate over whether the inflation target should be raised. We are in standard trade-off territory here. Economists generally agree a higher inflation target will in itself inflict greater costs on the economy, but they bring the benefit that the ZLB problem will occur less often. But there is an alternative, and clearly much better way out of this dilemma.

Governments have another instrument that has a reasonably predictable impact on aggregate demand, and which can be used to combat a recession: fiscal policy (changes to taxes and government spending). In the UK at the moment interest rates are at the ZLB in part because fiscal policy is contractionary (austerity). It would be far better to use this instrument to stimulate the economy in a recession than to raise the inflation target. Yet the institution of independent central banks have discouraged governments from using fiscal policy in this way.

It is no good central banks pretending that this is something which is up to governments, and that there is some unwritten law which means that central banks should keep quiet on such things. In reality, in both the UK and the Eurozone, the central bank actively encouraged governments to do the wrong thing with fiscal policy in the last recession. In other words, they encouraged austerity. If there is something inherent in the institution of a central bank that makes them give inappropriate advice in this way, then we should be asking how central banks can be changed as a matter of urgency.

What should happen in a recession, as soon as the central bank thinks that interest rates will hit the ZLB, is that central banks should say, out loud in public, that fiscal policy should become more expansionary. In addition central banks should say, out loud in public, that governments need not worry about rising debt and deficits due to the recession and any fiscal stimulus they undertake spooking markets because the central bank has that covered. Both statements have the merit of being true. 

Of course governments will need to restore debt to desired levels at some point, but that point should be well after interest rates have left the ZLB because then debt correction can be painless. The immediate aim of fiscal policy in a recession should be to allow interest rates to rise above the ZLB as soon as possible. That gives you the best macroeconomic outcome, and one that is far superior to raising the inflation target. The most important question facing central bankers today is why they failed to do that from 2009.

Now it is possible that, if democracy is in a bad shape (as it currently is in the US for example), the government may ignore the advice it receives from the central bank. In that case it is worth considering giving central banks some additional power to mimic a fiscal expansion, such as helicopter money for example. Or it may be worth considering institutional changes that allow nominal interest rates to go negative. Or raising the inflation target. But before doing any of those things we need to ensure that central banks give the right advice to governments when the next recession comes along.

Conservative zugzwang

Would really like to get back to macro, as some interesting things have been happening, but there are just too many compelling issues following GE2017 to talk about first.

The GE2017 result left the Conservatives in a position that chess players call a zugswang, which means whatever you do makes your position worse. They needed to turn to the DUP to get an overall majority, which leaves them with a secure hold on power. But that move in itself will lose them some popularity, kills their ‘coalition of chaos’ charge, and runs the risk of damaging Northern Ireland. The Good Friday agreement says that the sovereign should exercise power with “rigorous impartiality”. It will be up to the DUP to persuade Sinn Fein that all they are getting from the government is extra money for Northern Ireland. So to hold on to power, the Conservatives put the Northern Ireland peace process in jeopardy and give a gift to Labour.

The Conservatives will not fight another election with May as their leader. Their MPs, whatever they may say in public, are angry at her incompetence in running a campaign, putting together a manifesto, responding to the press, and almost everything else. The longer she stays in post, the longer the memory of that dismal campaign lingers and the more the brand gets tainted. However an election to replace her will reopen the split over Brexit which could tear the party apart.

Here is a worst case scenario. After the referendum, the Remain half of the party were in shock, and so they allowed May to define what Brexit meant. She did it in such a way as to ensure Hard Brexit, which will inflict considerable damage on the economy. Remain MPs felt they had no way of resisting that (few tried), but as Ruth Davidson made clear in any election in the near future they will be less passive, trying to elect one of their own who will perhaps keep the UK in the EEA (a Norway type deal), and certainly stay in the customs union. Leave MPs will do everything they can to stop that, and it is difficult to see this time their candidate mysteriously withdrawing before the membership are consulted. The Leave membership, with the help of the press, will choose the Leave candidate. Ruth Davidson might then declare independence from the main party.

It could be a terrible mess, spread out over time. It is a contest which will allow, with delicious irony, Corbyn to describe the Conservatives as too hopelessly divided to govern. Furthermore if they hold the contest while the EU negotiations are going on, Labour will justly accuse them of wasting precious time. But if they leave any contest until after the A50 negotiations have ended, the less time a new leader has to improve the Conservative brand, particularly when their majority makes them look powerless and ineffectual. It is a zugzwang.

The same applies to how they turn their fortunes around. The obvious move is to abandon austerity. The agreement with the DUP and other factors mean that the existing deficit targets will not be hit, so turning the deficit into surplus appears a distant prospect. But ending austerity in the mind of the voter means spending more on the NHS and schools. It should also mean reversing the cuts to in work benefits. However to, for example, match Labour’s spending commitments with some attractive alternatives of their own without raising taxes will blow the deficit. That would destroy the ‘we are competent because we cut the deficit’ line so carefully built up over seven years. To raise taxes will damage their core vote. Once again, a zugzwang.

You can add immigration. Fail to meet their target once again, and their credibility on this issue will be destroyed, but try meeting it and the economy is in serious trouble. Of course none of this means that the Conservative are bound to lose the next election. As a Conservative Prime minister once said, events dear boy, events. But for the party it means the liklihood that things will get worse before possibly getting better.

GE2017 and the Media

There is a danger of missing the point about Labour’s surge and the media. The issue is absolutely not that political commentators were surprised by Labour’s sudden popularity among voters. Of course they were surprised, because there was no evidence for it before May 2017. The dismal showing of Labour in the council elections at the start of May was real enough. Those on the left who say they knew it would happen are using the word ‘knew’ in the same sense as football supporters knowing their own side is going to win.

We all have a pretty good idea why the surge happened. In style Corbyn was everything May was not, and Labour’s policies were popular. What the media should be worried about was that both those things came as a surprise to the public. As I said here, a general election campaign is unusual because the public get to see much more of the party leaders and hear much more about their policies, and the broadcasters are duty bound to be impartial. But the character of May and Corbyn did not change overnight, and neither were the policies offered by either side very different from the stance they took before the election. So why were people so surprised?

Someone more cynical than I might suggest that the media’s job is to distort reality: to portray May as more competent than she was and to portray Corbyn as incompetent. What happened in the election campaign is that the electorate got a proper look at the two main leaders and their policies, and realised what the media had been saying was false.

That cynical view is completely appropriate to most of the right wing press, whose job is to distort reality as much as they can get away with. (Remember that damning article about May just before the election that was pulled by the Telegraph?) But why did the truth about May and Corbyn not make any impression on the public until the election? Did political commentators know no more than the public, and were just as surprised as the public about May and Corbyn’s character and their policies during the campaign? If that is the case, they were poor journalists. Or is it that they failed to communicate what they did know?.

Is the problem that the broadcast media feels duty bound to just present soundbites (May can do those), and the independent press in the UK is just too small? Or is the problem that the right wing media for one reason or another sets the parameters for other journalists. Is it that political journalists like winners and despise losers, so let the polls influence how they portrayed individuals and parties? I do not know the answers, but these are the questions the media needs to reflect on.

Labour and its Left

The 1980s were a battle between what eventually became New Labour, and what is often referred to as the Hard Left. 1983 to 1997 was a long period where the Hard Left gradually lost influence within both the party (then the membership and trade unions) and among the parliamentary party (the PLP). But this didn’t mollify the distaste New Labour had for the Hard Left.

This period meant that those opposing the left adopted two propositions which became almost hard-wired into their decisions.

  1. The left within Labour were more concerned with controlling the party than winning elections. That has often been said about Jeremy Corbyn over the last two years.

  2. That the Left, and their ideas and policies, were toxic to most voters. The right wing press assisted in this by talking about the loony left.

In short, it was best to act as if Labour’s Left were a political pariah. As a result of these ideas the left minority within the PLP was tolerated (Labour needed to be a broad church), as long as it remained small and powerless. Triangulation became the way to win power: to adopt policies that were never from the Left, but adopted a centre ground between the Left and the Conservatives. New Labour was not old Labour.

The strategy was extremely successful. Tony Blair won three elections, and it took the deepest recession since the 1930s to (just) remove Labour from office. The Blair government achieved a lot, particularly for the poor, but it also made serious mistakes, most notably Iraq. That stopped a lot of those on the left actively supporting the party.

In 2015, when Labour under Ed Miliband was defeated, the general mood among the PLP seemed to be that it needed to triangulate once more and move further to the right. Crucially, some leading figures suggested Labour should all but embrace George Osborne’s austerity policy. The three main candidates to take over from Miliband were seen (with justification or not) as representing this thinking. Austerity was a critical issue, in part because - if accepted - it potentially constrained what Labour could do to a large extent. It was also an economically illiterate policy, which I can safely say with authority. Worse than that, it was a policy that - as the deficit fell - began to lose its popularity, so for Labour to adopt it at just the point it was losing its popular appeal seemed a doubly crazy thing to do.

Before Corbyn won that election I wrote
“Whether Corbyn wins or loses, Labour MPs and associated politicos have to recognise that his popularity is not the result of entryism, or some strange flight of fancy by Labour’s quarter of a million plus members, but a consequence of the political strategy and style that lost the 2015 election. …. A large proportion of the membership believe that Labour will not win again by accepting the current political narrative on austerity or immigration or welfare or inequality and offering only marginal changes to current government policy.”

At this point I was receiving impassioned pleas by some to come out against Corbyn. These mainly went along the lines that Corbyn was unreformed from the 70s/80s, and wanted to take over the party for the ‘old left’. Many said he could not win an election because his policies would be too radical. He would be a disaster with the electorate. It was unmodified 1980s thinking. These arguments sounded unconvincing to me, mainly because Corbyn would have to work with the PLP. Unlike the 1980s, the left were now such a small minority within the PLP that they would have no other choice.

As I had anticipated, Corbyn and McDonnell did form a shadow cabinet of all the (willing) talents, and as far as economic policy was concerned they were far from radical. McDonnell set up the Economic Advisory Council (EAC), which I and I suspect others were happy to join because it involved no endorsement of Labour’s policies. Arguments that we should have withheld our advice because Corbyn was somehow ‘beyond the pale’ were again straight from the post-83 playbook, and I am very glad that I ignored them. I helped Labour adopt a fiscal rule which in my view exemplified where mainstream macroeconomics was, and which incidentally some sections of the Left were very critical of. It formed a key part of their 2017 manifesto

What I had not anticipated, back when Corbyn was about to be elected, was how foolish some Labour MPs would be in those months following his election. Critical briefing of the press was constant, and tolerated by many in the PLP. As I wrote at the time, this strategy was stupid even if you hated Corbyn, because it gave the membership the excuse to ignore Corbyn’s failings. I was more right than I could have imagined. This was the first major mistake that the PLP made after the election.

The other thing I had not anticipated was Brexit. This triggered the second major mistake by the PLP, which was the vote of no confidence. It was in many cases an emotional reaction to Brexit, the leadership’s role in the campaign and earlier incompetence. It was understandable, but it was nevertheless terrible politics. Corbyn’s supporters were gifted the perfect narrative in the subsequent leadership election: the PLP had sabotaged Corbyn’s leadership.

The two mistakes made by the PLP ensured that for many members the 2016 vote became the PLP against the membership. One big mistake Owen Smith made was to not side with the membership in terms of changing the 15% leadership rule, so naturally they said if you do not trust us we will not trust you. Nevertheless I supported Smith over Corbyn, because I could not see a future for a party that had become so deeply divided. I thought the next election was winnable for Labour, but not if the party was seen by the electorate as at war with itself. That was one of the key reasons I resigned from the EAC: whether that was the reason three others also left I cannot say.

After Corbyn won for a second time, the polls suggested Labour’s future was bleak. This is what led May to call her snap election. However two things happened after Corbyn’s re-election which surprised me and many others, and meant that my predictions of no future under Corbyn proved wrong. First, the internal squabbling within Labour stopped almost completely. Second, the leadership started putting together a manifesto that would prove very popular, with a competence that had earlier been missing. During the general election divisions within Labour were not part of May’s main attack, in part because she chose to make the campaign presidential in style..

Many will say that Labour achieving 40% of the popular vote vindicated the membership’s faith in Corbyn. Others will go further and say ‘if only the PLP had been more cooperative we could have won’. That is going too far..The election result was also a consequence of a truly terrible Conservatives campaign, headed by a Prime Minister who exposed herself as just the wrong person to lead the country through Brexit  The economic environment couldn’t have been better for Labour: unlike 2015 we had falling real wages and the slowest quarterly GDP growth rate in the EU. Labour’s manifesto held out hope, while the Conservative manifesto was a liability. Despite all this, the Conservative vote share was above Labour.

What the election does show beyond doubt is that the attitudes most of the PLP had towards the Left, which they had carried with them from the 1980s, are no longer appropriate. The result was not the disaster they had been so sure would happen. That showed some left wing policies can be very popular, even if they are called anti-capitalist by those on the right. The curse of austerity on the UK electorate has lifted. Unlike the ‘dementia tax’, none of the policies in Labour’s manifesto proved to be a millstone around Corbyn’s neck. The days when Labour politicians needed to worry about headlines in the Mail or Sun are over.

The big lessons of the last two years are for Labour’s centre and centre-left. The rules that applied in the 1980s no longer apply. The centre have to admit that sometimes the Left can get things right (Iraq, financialisation), and they deserve some respect as a result (and vice versa of course). The centre and Left have to live with each other to the extent of allowing someone from the Left to lead the party. Corbyn has shown that the Left are capable of leading with centre-left policies, and the electorate will not shun them. With the new minority government so fragile, it is time for the centre and centre-left within Labour to bury old hatchets and work with Corbyn’s leadership.

Why has the US resisted Trump but the UK acquiesced to Brexit?

This post is a response to a provocative piece by Anatole Kaletsky. He writes
“While the US has taken only 100 days to see through Trump’s “alternative reality” (though perhaps not through Trump himself), almost nobody in Britain is even questioning the alternative reality of Brexit.”

In other words, although both the US and UK succumbed to right wing populism, the US is strongly resisting while the UK has given up doing so. He contrasts the reaction of business to Trump and Brexit. “US businesses started lobbying immediately to block any Trump policies that threatened their economic interests” which has “removed Trump’s main protectionist threat.” In contrast “no major British companies have tried to protect their interests by campaigning to reverse the Brexit decision. None has even publicly pointed out that the referendum gave Prime Minister Theresa May no mandate to rule out membership of the European single market and customs union after Britain leaves the EU.”

One reaction that many will have is that while US elections are 4 year affairs, a referendum was meant to be ‘for a generation’. If the Leave vote had been 60% or more, I might have some sympathy with this view. But the narrow victory coupled with uncertainty about what Brexit actually entails means that the argument for a vote after negotiations conclude is compelling. But only around 30% of people support being allowed a second vote. In contrast, currently 56% of US voters disapprove of Donald Trump.

You could say this is because Donald Trump has done plenty of things for US voters to get angry about, whereas Brexit has not happened. I would put the point rather differently. The problems with Trump are visible to everyone. You just need to read his tweets! The costs of Brexit are economic and less clear to everyone. For example the depreciation immediately after Brexit was very visible, but you needed some knowledge of economics to know that this would mean lower living standards for everyone living in the UK.

This gets translated into how each are handled in the media. The New York Times and the Washington Post are in the front line against Trump, while if you want information on how Brexit is damaging the economy you will find plenty of it in the Financial Times. But that negative news does not normally make it into the broadcast media, because the broadcast media has decided that the Brexit debate is over. The reason it has done that is the real reason why the UK appears to have given in to Brexit, which is the Labour party.

It is difficult to get ideas discussed in a sustained way in the broadcast media unless one of the two major political parties is pushing it (see, for example, opposition to austerity before Corbyn). In contrast to the Democrats, who have been unified in their opposition to Trump, Labour have accepted Hard Brexit. It would be unfair to dump the whole responsibility for Labour’s Brexit U-turn on Jeremy Corbyn. Many Labour MPs pushed in the same direction because they thought it would gain them votes: austerity appeasement all over again. I think a strong leader who believed in EU membership could have overcome that, but Corbyn’s preferences were different.

As a result, we have had a general election supposedly about who will be best at negotiating Brexit without any discussion of Brexit itself. Despite the LibDems best efforts, there has been no discussion of all the events since the referendum which indicate bad times ahead, as outlined by Ian Dunt. There has been endless discussion about how taxes and spending might change under Labour or the Conservatives, but none about the elephant in the room: the cuts or tax increases that Brexit and lower immigration will require. There is a hope, expressed by Bill Keegan, that today’s vote may lead to a hung parliament, which in turn might just lead to a second referendum, but it is a very slim hope.

It may also be the only hope. George Eaton may well be right that Labour’s decision to back a Hard Brexit has helped them in this election. The danger is that Labour will draw the lesson that this will be true in 2022 as well, and their new leader (if there is a new leader) will also commit to hard Brexit. Again the austerity mistake will be repeated: assuming the electorate's attitudes will remain unchanged. If that happens, we may well see in four years time a rejuvenated US with a Democrat in the White House and Republicans routed because of their association with Trump, but a UK entering a long period of relative decline and isolation because it gave in to right wing populism.

Could austerity’s impact be persistent

How Conservative macroeconomic policy may be making us persistently poorer

I was happy to sign a letter from mainly academic economists published in the Observer yesterday, supporting the overall direction of Labour’s macroeconomic policy. I would also have been happy to sign something from the Liberal Democrats, who with a similar macroeconomic stance have the added advantage of being against Brexit, but no such letter exists. As I have said before about letters, it is the overall message that counts. We desperately need more public investment and more current spending to boost demand, which in turn will allow interest rates to come away from their lower bound.

If I could carry just one message into mediamacro to bring it more into line with macro theory, it is that nominal interest at their lower bound represent a policy failure. Unconventional monetary policy is a very unreliable substitute for interest rate changes and fiscal policy as a way of controlling the economy, and a temporary fiscal stimulus can reliably get interest rates off their lower bound. This was the big mistake that most advanced countries made in 2010, and painfully slow recoveries were the result. The UK is currently making the same mistake, which is why the macroeconomic impact of the Labour and LibDem programmes is so much better than the Conservatives’ continuing austerity.

In the textbook macroeconomic models, this policy mistake can have a large but temporary cost in terms of lost output and lower living standards. This is because in these basic models a short term lack of demand does not have an impact on supply. Output in the longer run is determined by the number of those wanting to work, the capital stock and technology, all three of which are assumed to be independent of short term demand shortages. However it looks increasingly like these textbook models can be wrong.

In a new study (pdf), Gustav Horn and colleagues at the IMK institute in Germany looked at how persistent the impact of negative fiscal shocks (higher taxes or lower spending) had been on output. Their analysis is a refinement of earlier studies by of Blanchard and Leigh, and more recently Fatas and Summers. They find that the impact of recent fiscal shocks have been persistent rather than temporary, at least so far.

Although this persistent impact is not part of textbook models, economists have explored effects of this kind (the collective name for which is ‘hysteresis’). There are many theories about why it could happen, such as theories of endogenous growth. I explored the idea of an innovations gap in a recent post. To see why this possibility is so important, take the example of UK austerity in financial years 2010/11 and 2011/12. A few years ago I took the OBR’s (conservative) assessment of its impact on GDP growth in those two years, and assumed that the impact of fiscal consolidation had completely unwound by 2013. That gave you a total cumulated cost of austerity of 5% of GDP (1+2+2), or £4,000 per household.

What happens if instead the impact of austerity is much more persistent? I can no longer use the OBR’s numbers, because they assume impacts die out over time. Instead, let me make the fairly conservative assumption that each 1% reduction in the cyclically adjusted deficit reduces GDP by 0.7%, but these effects are permanent. I’ve chosen 0.7 because that gives a similar answer for the cost of austerity by 2012 as my previous calculation. But rather than disappearing in 2013, these cost persist and grow with each additional act of consolidation. By 2016/17 GDP would be lower by nearly 4%, and a further 1% would be added by the planned additional austerity until 2019/20. If you accumulate those losses, it means that the average household would have lost a staggering £13,000 by 2016/17, rising to £23,000 3 years later.

If you think that sounds a ridiculously large number, just compare output or income relative to past trends. Here is a version from the IFS.


Once you see this data, claims that we have a strong economy become laughable. UK median incomes are currently over 15% below previous trends. That is more than enough room to accommodate 4% due to a permanent effect from austerity.

I do not have to argue that such permanent effects are certain to have occurred. The numbers are so large that all I need is to attach a non-negligible probability to this possibility. Once you do that it means we should avoid austerity at all costs. In 2010 austerity was justified by imagined bond market panics, but no one is suggesting that today. The only way to describe current Conservative policy is pre-Keynesian nonsense, and incredibly harmful nonsense at that. That was why I signed the letter.

What does Labour's poll surge tell us

This isn’t another discussion about whether Labour can ‘win’: I’m far less qualified than others to make predictions of that kind. Nor is it the appropriate point to ask whether the Parliamentary Labour Party (and to a lesser extent myself) were wrong to think a Corbyn leadership would be disastrous: that discussion should be postponed for a week. Instead I want to ask what the Labour surge tells us about the way political information has been disseminated in the UK.

Sir David Butler says “the movement in the polls over this campaign is bigger than in any election I’ve covered since 1945”. (Some data here.) There are three obvious explanations for this surge. A terrible Conservative campaign which led many to think Theresa May had serious failings, a good Labour campaign which led many to think Jeremy Corbyn was not the ogre some said he was, and a Labour manifesto which contained popular policies. The point I want to make is that none of those developments should have come as a surprise. Yet to the parts of the electorate that created the surge they have been a surprise enough to change their vote.

I have talked about Theresa May in an earlier post, and none of the failings that the campaign has exposed were out of character. For example the ‘dementia tax’ U-turn was little different to the U-turn on self-employed tax. One thing that was clear about Jeremy Corbyn is that he runs good campaigns, and the idea that his appeal would be precisely limited to Labour party members was never likely to be true. (Whether it can extend to older Conservative voters we have yet to see.) Finally it was clear to me from the start of his leadership that he would try and adopt policies that were popular, robust and which most MPs could live with. Those that suggest the manifesto marks the end of UK capitalism have no credibility, as an examination of other European countries would demonstrate.

So if May’s weaknesses and Corbyn’s strengths were pretty clear before the campaign began, why have they come as a surprise to those involved in answering the questions of pollsters? The difference between an election campaign and everyday politics is that in a campaign politicians get more time to talk directly to the people. Outside of a campaign, politicians have to rely more on the media to get themselves and their policies across. So part of the story behind the surge is a failure of the media to accurately portray the abilities of politicians. [1]

I’m not talking on this occasion about the bias of the Tory press, because if this was all we would see swings to Labour during every election campaign, and that normally does not happen. More important I think is a failure of centrist and left leaning commentators, who almost all took one side in Labour’s internal divisions. The impression many gave was that Corbyn was hopeless and his policies would be laughed out of court. When neither turned out to be true, his and his party’s popularity improved dramatically

Unfortunately for Labour supporters there is a potential corollary. One idea I have seen put forward is that the polls may be exaggerating the surge because those being polled are paying more attention to the campaign than the average voter. All of the factors I identified above may be having proportionately more impact on voters being polled. (This might explain why many Labour MPs say they do not recognise this surge.) All the more reason to leave retrospectives on Corbyn's leadership until after the vote.

[1] Another factor is Brexit. May emerged as Conservative party leader in chaotic circumstances, without even having to win a contest among Conservative party members. In such chaos, she did not get the scrutiny she deserved. Politics since then has been mainly about Brexit, and while the Conservatives largely united behind May, Labour were more divided. The election was a reminder that other really important issues exist.

GE2017 and the stages of Leaver grief

After the Brexit vote, various people had fun talking about the stages of Remainer grief, going from denial through bargaining (we can still reverse this) to acceptance. But I think there is an analogous process for Leavers, where they begin to regret their decision and realise that they have made a serious mistake. For many of them we are in the bargaining stage, where somehow the situation can be retrieved as long as the negotiations with the EU are handled well. For them this is what the election is about.

We have to start with one interesting fact that should be noted more often. As YouGov’s Brexit tracker shows, the UK remains as divided on the issue of Brexit as it was a year ago. As I have noted before, this is slightly surprising, because over the last year it has become clear to most Leavers that Brexit will involve a cut in their standard of living, whereas before the vote most Leavers did not expect this and furthermore reported that they did not regard a cut in their living standards as a price worth paying to reduce immigration. But voting Leave was about much more than economics, so people are likely to be reluctant to admit they made a mistake that quickly. As Mark Twain said, “It's easier to fool people than to convince them that they have been fooled.”

Hence the stages of grief for Leavers. They have been led to believe, by newspapers and politicians, that as long as the negotiations are played right all will be well: the bargaining stage of grief. Unfortunately for them they are still living in the fantasy world created by the Brexit media and unchallenged by the broadcast media. The fantasy is to view the forthcoming EU negotiations as some great battle of wills. As Stephen Fisher notes, the negotiations are constantly framed in pugilistic terms. This is why the Conservatives are polling at around 45%, despite all the mistakes of the Tory campaign.

Hence, also, the attraction of the ‘no deal is better than a bad deal’ line. Leavers need to believe that walking away is a credible threat that will unlock the benefits of Brexit. But the reality is painfully different. If you want an eloquent explanation of this read Martin Wolf if you can, otherwise here is the short version. The EU knows that No Deal would be a disaster for the UK. It would be painful for the EU too, but not so painful as to make them offer the UK any significant favours. Their overriding objective is to ensure the UK will be worse off under Brexit, not as some punishment but to ensure EU survival. Given that No Deal will be so much worse for the UK than the EU, and as the clock is already ticking, the EU are in a position where they can pretty well dictate terms. To the extent that this is a game, we lost it the moment Article 50 was triggered.

The EU negotiations are still very important, but for the UK it is more a matter of making choices rather than extracting concessions. There are many kinds of Brexit. In thinking about who would be the best negotiator for the UK, the most important question to ask is who would make the right choices. Theresa May, by focusing so much on immigration and the European court, has already made two very bad decisions. She seems to be rather good at bad decisions. Personal qualities matter to a lesser extent, but success involves empathy and trust, not obstinacy. [1]

Unfortunately much of the country is still lost to the fiction that the negotiations are a battle of wills where the UK can emerge victorious if it is stubborn enough. While the ‘strong and stable’ line did not survive inspection, I suspect the ‘coalition of chaos’ mantra will begin to work in the last week of the campaign if the polls tighten. Hugo Dixon makes a strong case that in reality a hung parliament would actually be a good thing in many ways. However it is a case that is very difficult to get across in short soundbites, and the fact that there are a multitude of permutations will sound like chaos to many. In addition, the various possibilities are the stuff political commentators love talking about (see GE2015), so this apparent chaos will get plenty of airtime. That, despite her best efforts, should see May through to a decent majority on 8th June.

But this will not put an end to Leavers grief, but just delay and heighten it. Depression is likely to follow as the reality of the negotiations become clear. In all likelihood the economy and real wages will continue to stagnate, and the improvement in public services promised by the Brexiteers will not materialise. Theresa May once warned that the Conservatives had become known as the nasty party. Her actions now are ensuring that it forever becomes known as the party that embraced a disastrous Brexit.

[1] Her lies are also getting worse. At least ‘I’m calling the election because I need a strong mandate’ sounded plausible until you thought about it, but ‘I’m not joining a debate because I’m busy preparing for the negotiations’ wouldn’t fool a 10 year old.

Growth will be lower if the Conservatives win

The Conservatives want Brexit to be the central issue in this election. Partly as a result, the relative macroeconomic outlook under the different parties has not been discussed as much as it should, or as much as it was in 2015. The other reason it has not been discussed very much is that the economic record of the last seven years has been dire, but prospects under either Labour or the LibDems would be distinctly better. [1]

The last seven years have seen an extraordinary decline in real wages. To quote Rui Costa and Stephen Machin:
“Since the global financial crisis of 2007/08, workers’ real wages and family living standards in the UK have suffered to an extent unprecedented in modern history. Real wages of the typical (median) worker have fallen by almost 5% since 2008, while real family incomes for families of working age have just about recovered to pre-crisis levels.”

This stagnation in real wages is greater than any other advanced economy bar Greece. [2] In addition, as Laura Gardiner from the Resolution Foundation points out, current government policies imply the “biggest increase in inequality since Thatcher”. The less you earn, the more this government plans to take income away from you.

The Conservative response is to point to record levels of employment, and to keep saying ‘strong economy’. But these two apparently diverse developments, high employment and falling real wages, may be related in a very simple way: workers may have been forced to price themselves into jobs by keeping real wages low, or workers who might otherwise have retired are continuing to work to earn enough for their old age. When high employment is a symptom of no growth in living standards, it is nothing to cheer about. They both reflect a weak rather than a strong economy.

The different party manifestos have been discussed at length, but one aspect that has been almost totally ignored by the media has been their different macroeconomic implications. A lot of the responsibility for this lies with the IFS. As I wrote in a recent tweet, the “problem with IFS analysis of manifestos is not just the absence of macro dimension, but their failure to acknowledge it even exists.” **

Both the Labour and LibDem manifestos amount to an increase in public investment, and an increase in public spending financed by higher taxes, compared to current government plans. Standard macroeconomics implies that both higher investment and spending will lead to an increase in GDP, unless the Bank of England raises interest rates to exactly offset this effect. With interest rates currently stuck at their lower bound, and with public investment helping aggregate supply, that last possibility is extremely unlikely. The conclusion therefore has to be that GDP over the next few years would be higher under a Labour or LibDem government than under the Conservatives.

This is why, according to Larry Elliott, Oxford Economics estimate that “the economy would be 1.9% bigger under the Lib Dem plans and 1% bigger under Labour’s plans than under Conservative plans.” The argument that this cannot be done because it would involve some more borrowing is rightly dismissed as pre-Keynesian nonsense. It is for this reason that the IFS approach of ignoring macro is so helpful for the Conservatives. I understand that the IFS does not do macro, but its failure to even mention this gap in their analysis not only encourages mediamacro, but in the current situation represents a clear bias towards the Conservatives.

This is not the only reason why living standards would be significantly higher under a Labour/Lib Dem government. Just as the IFS ignores macro, I fear Theresa May ignores economics. In this post I noted her obstinate refusal to take foreign students out of their net migration target (causing considerable damage to one of our leading export industries), but more generally her obsession with reducing immigration is likely to do further damage not just to the public finances, but output and living standards too. It is increasingly clear that while the the coalition government (and in particular George Osborne) had no intention of meeting their immigration target, May regards it as an unfulfilled commitment despite the economic damage this would do. This marks a big difference between the Conservatives and Labour.

Finally, in comparing the economic outlook under a Conservative or alternative government, we should not ignore Brexit. After my previous post outlining why May is in many ways unsuited to the forthcoming EU negotiations, some comments were along the lines that surely Corbyn would be worse. I think not, for two reasons. You have to put out of your mind the government’s and media’s framing of these negotiations as some kind of poker game or battle of wills. They are much more like a cooperative exercise involving give and take. I see clear reasons for thinking that May/Davis will be worse at this than Corbyn/Starmer. Last but not least, I think there is no chance of a No Deal outcome under Labour, but a significant chance that the Conservatives would walk away. As Ben Chu points out, what is best for the UK economy might well be rather different from what Theresa May sees as best for Theresa May.

If the last 10 days of the campaign seem to ignore the outlook for the economy, there will be a very simple reason why. As a result of the manifestos, attitudes to immigration and Brexit, the UK economy will be better off and subject to less risk if Theresa May is no longer the Prime Minister after 8th June.


[1] Implicit in these two sentences is that the Conservatives tend to dictate the issues discussed by the media during an election, as was clearly the case in 2015.

[2] See also this New York Times piece from Simon Tilford, which presents a rounded picture of our performance relative to other European countries, rather than the carefully chosen snippets beloved by the government's spin machine.

** In the original version of this post I said that the IFS analysis assumes GDP would be fixed. This is incorrect: what I had missed is that they do allow a short term impact from additional public investment on GDP (see slide headed 'Impact on the Economy' here). However this slide illustrates exactly the concern I have.
(1) It makes no sense to allow a short term impact from public investment, but no short term impact from a balanced budget increase in public spending.
(2) The slide says that the long term positive impact of this public investment on GDP will be exactly offset by the macro impact of a higher minimum wage and additional public holidays. Is this a result of detailed macro analysis, or just a convenient assumption?
(3) The slide also says that the Conservative commitment to reduce immigration would weaken growth and public finances, but despite this they assume no impact of lower immigration on growth. This makes no sense whatsoever, unless we are working backwards from the fixed long run GDP assumption.
