The biggest economic policy mistake of the last decade, and it had nothing to do with academic economists


"The biggest policy mistake of the last decade" is the title of an article by Ryan Cooper, and the mistake is of course austerity. (It is a very US focused piece, so Brexit is not on the map.) Cooper goes through all the academics who gave reasons why austerity was necessary and how their analysis later fell to bits. (How much they fell to bits is still a matter of dispute as far as these authors are concerned.)

Here is his concluding paragraph:
“As we have seen, the evidence for the Keynesian position is overwhelming. And that means the decade of pointless austerity has severely harmed the American economy — leaving us perhaps $3 trillion below the previous growth trend. Through a combination of bad faith, motivated reasoning, and sheer incompetence, austerians have directly created the problem their entire program was supposed to avoid. Good riddance.”

There is a lot I could say about the details of the article, but this conclusion is essentially correct, and it applies at least as much to the UK and to the Eurozone countries. With Trump’s large tax cuts for the rich paid for in large part by borrowing, the Republicans can no longer credibly tell everyone austerity is essential. In contrast the political right’s enthusiasm for austerity in Europe remains strong.

Reading the article brought back memories of my first year or two writing this blog, where I became part of a mainly US blog scene of mainstream academics opposed to austerity, lead by Paul Krugman and Brad DeLong. We were trying to take down the academic arguments for austerity, and we succeeded. As Cooper’s article suggests it was not a very difficult task. Sometimes very senior economists who should have known better made simple mistakes of the kind I discussed here. On other occasions, like the predictions of massive inflation from Quantitative Easing that Cooper discussed, events quickly proved the Keynesians correct. Only in the case of the studies from the two pairs of Alesina and Ardagna and Reinhart and Rogoff was additional research required to challenge their conclusions.

As far as us Keynesians were concerned, the intellectual battles were won by the end of 2012 if not before. In particular Paul De Grauwe’s influential analysis of why Eurozone countries were experiencing a debt crisis, pointing to the lack of a sovereign lender of last resort, put an end to the academic credibility of ‘we are going to become like Greece’ stories. When the ECB introduced OMT in September 2012 and the Eurozone debt crisis came to an end De Grauwe was proved right. In 2013 Krugman wrote of austerity:
“Its predictions have proved utterly wrong; its founding academic documents haven’t just lost their canonized status, they’ve become the objects of much ridicule.”

What we didn’t know for sure then was the lasting damage that austerity would bring, and which Cooper notes.

I want to add two important points that Cooper’s article does not cover. The first is that although by 2013 most academics had become convinced about the austerity mistake (it was always a minority view anyway), economic journalists in the non-partisan media could not recognise that because the politicians were continuing to implement the policy. Here is Robert Peston in 2015:
“And before I am savaged (as I always am) by the Krugman crew of Keynesian economists for even allowing George Osborne’s argument an airing, I am not saying that the net negative impact on our national income and living standards of cutting the deficit faster is less than their alternative route of slower so called fiscal consolidation. I am simply pointing out that there is a debate here (though Krugman, Wren-Lewis and Portes are utterly persuaded they’ve won this match – and take the somewhat patronising view that voters who think differently are ignorant sheep led astray by a malign or blinkered media).”

We now know that voters were indeed being led astray by a malign or blinkered media, or at least a media that did not have the courage to call the result of the academic debate.

The second point is that this academic debate had zero impact on politicians. In that sense Cooper’s article is of purely academic concern. Austerity was not begun because politicians chose the wrong academic macroeconomists to take advice from, and the fact that the Keynesians won the debate therefore had no impact on what they did. The academic debate was in this sense a complete sideshow. I think many Keynesian academics understood that: it was a fight we had to win but we were under no illusions it would change anything. I wrote in 2012 that if all academics were united we might have an impact on public opinion, but that illusion did not last very long and Brexit showed it was indeed an illusion.

I think this lack of influence that academic economics can have is not understood by many. It often suits some heterodox economists to pretend otherwise. Economists can be influential, but only when politicians want to listen, or the media is prepared to confront them with academic knowledge. For example politicians have not done nearly enough to ensure another financial crisis does not happen, but that isn’t because economists have told them not to or have not shown them how to do so. It is because politics prevents it happening.

The reason why economists like Alesina or Rogoff featured so much in the early discussion of austerity is not because they were influential, but because they were useful to provide some intellectual credibility to the policy that politicians of the right wanted to pursue. The influence of their work did not last long among academics, who now largely accept that there is no such thing as expansionary austerity or some danger point for debt. In contrast, the damage done by austerity does not seem to have done the politicians who promoted it much harm, in part because most of the media will keep insisting that maybe these politicians were right, but mainly because they are still in power.

Misrepresenting academic economists

Brad DeLong entered the debate between myself and Unlearning Economics with a post entitled “The Need for a Reformation of Authority and Hierarchy Among Economists in the Public Sphere”. He writes
“Simon needs to face that fact squarely, rather than to dodge it. The fact is that the "mainstream economists, and most mainstream economists" who were heard in the public sphere were not against austerity, but rather split, with, if anything, louder and larger voices on the pro-austerity side.”

The dodge, and I think it is a pretty good dodge, is that politicians and a good part of the media choose the economists they publicise. If you accept that austerity came from what I call deficit deceit - an attempt to reduce the size of the state using the false pretext of deficit reduction - then obviously politicians and their supporters in the media would choose those economists whose views were useful in promulgating that deceit. As the UK discovered during the Brexit debate, even a tiny proportion of economists (8!) can appear much larger if the media gives them much more attention than they deserve.

But the argument remains a dodge in the following respect. How were people outside economics, including much of the non-partisan media, meant to know that particular academic economists were unrepresentative of the majority? Indeed how can even economists be sure of this? I’ve argued that the majority of academic macroeconomists were always against austerity, particularly once the reason for the Eurozone crisis had been resolved by Paul De Grauwe, but the evidence I use to back this up is piecemeal and indirect (see here, pages 3 to 4).

Part of the problem is a certain disregard for consensus among economists. If you ask most scientists how a particular theory is regarded within their discipline, you will generally get a honest and fairly accurate answer. In contrast economists are less likely to preface a presentation of their work in the media with phrases like ‘untested idea’ or ‘minority view’. In macro it also reflects periods in the past, which still resonate today, when there was deep division and antagonism between different groups. This extends to not being sure what is taught at masters level in the top schools: it turned out, when AndrĂ© Moreira and I did the research, that there was more consensus in one key respect (Chicago excluded) than some had imagined.

Part of Brad’s post it seems to me is simply a lament that Reinhart and Rogoff are not even better economists than they already are. But there is also a very basic information problem: how does any economist, let alone someone who is not an economist, know what the consensus among economists is? How do we know that the people we meet at the conferences we go to are representative or not?

To help fill that gap we have in the US the IGM Economic Experts Panel survey, and in the UK/Europe the CFM survey. (The IGM survey has recently started a European version.) The US IGM survey has asked a question about the Obama stimulus package on more than one occasion, and the latest result is here. It is one key part of the evidence for my claim that most academics were and are against austerity.

However all these surveys share a common feature which I find problematic, and which also reflects on Brad’s concern. They are selective, and deliberately designed to only include the academic elite. IGM writes that panel members are all senior faculty at the most elite research universities in the United States. So they tell us not what academic economists think, but what a chosen sample of ‘elite’ economists think. Now if those samples are well chosen, as I think they mostly are for these surveys, that may not matter too much, but how representative they are can always be questioned. It also gives the impression that it is only this elite that are worth listening to when it comes to policy issues, something I think is simply wrong as well as being elitist.

As part of the build up to the Brexit vote, the Observer newspaper commissioned Ipsos MORI to email all members of the Royal Economic Society. 91% of those who responded thought Brexit would have a negative impact on UK GDP in the longer term. As most UK academic economists are RES members, it was therefore possible to say that there was a clear consensus among academic economists that Brexit was harmful. To be able to say this about all economists, rather than just a select few, in my view strengthens the power of the survey. (Some defend elitist surveys because the elite is ‘influential’, but if they influence their fellow economists that will show up in a larger sample.)

I think the experience with austerity and Brexit suggests it is time for national economics associations (like the RES or AEA) to start representing the opinions of economists by conducting such polls of their members under their own initiative. With email addresses the technology makes it easy to do. It is time these organisations started telling both us and the world about what the consensus (if any) is on key policy issues. It would be an important step towards ending the misrepresentation of economists and economics.

The non-independent ECB

Imagine that the Scottish National Party (SNP) had won the independence referendum. The SNP starts negotiating with the remaining UK (rUK) government over issues like how to split up national debt. On some issue the negotiations get bogged down. Rumours start circulating that this might mean that rUK will not form a monetary union with Scotland, and that Scotland might have to create its own currency. People in Scotland start withdrawing money from Scottish banks.

Now it is almost the definition of a private bank that if everyone who has an account at the bank wants to withdraw their money, the bank will run out of cash and go bust. That is why bank runs are so dangerous. It is also why one of the key roles of a central bank is to supply an otherwise solvent private bank with all the cash they need, so they will never deny depositors their money. (To be a lender of last resort.) If they did not do this, anyone could start a rumour that a bank was insolvent, and as people withdrew their cash just in case the rumour was true, the bank would run out of money and go bust anyway.

So in my hypothetical story, as people started withdrawing cash from Scottish banks, the Bank of England should supply these banks with all the cash they need. Except suppose it did not. Suppose it put a limit to the amount of cash it would supply. The Scottish banks would protest - you agreed we were solvent before independence, they would say, so why are you rationing our liquidity? The Bank of England replies that although they might have been solvent before independence, if there is no agreement solvency is less clear. The Bank of England says that the limit on cash will remain until the Scottish and rUK government come to an agreement.

This announcement of course leads everyone in Scotland to try and get their money out, and the Scottish Banks have to close. The Scottish economy begins to grind to a halt. The English media report that Scotland is running out of money because the Bank of England will not ‘lend’ any more to the Scottish banks. The Scottish government is forced to agree to the rUK’s terms. The English media say look what happens when you elect a radical government. In Scotland they call it blackmail. What would you call it?

If it sounds to you like the Bank of England is taking sides and putting impossible pressure on Scotland, then you will know what it feels like in Greece right now. When, on 28th June, the ECB stopped providing emergency funding to Greek banks, it took sides. Part of the ECB’s logic is that Greek banks may be insolvent if there is no agreement between the Troika and Greece (even though it is the Central Bank of Greece, and therefore the Greek people, which stands to suffer losses from defaults by commercial banks).

Why should the failure to reach an agreement influence the solvency of the Greek banks? Is it because without an agreement there would be a Greek exit? But Greece does not want to abandon the Euro, and the other Eurozone countries have no formal grounds to expel Greece. Greece will only leave the Eurozone if the ECB stops supplying Euros. We reach exactly the same self-fulfilling logic of a bank run. Is it because without an agreement the Greek government would default on some of its debts, and that might adversely influence the solvency of Greek banks? But the fact that the Greek government will not get money from the Troika to pay back the Troika seems to have no implications for the underlying solvency or either the Greek state or its banks. (Paul De Grauwe discusses this further.) If the Troika can make Greece insolvent by itself withholding money we have another self-fulfilling justification.   

The real explanation for the ECB’s actions is much simpler. Limiting funding on 28th June was the Greek government’s punishment for failing to agree to the Troika's terms and calling a referendum the day before. The ECB was not, and never has been, a neutral actor just following the rules of a good central bank. It has always been part of the Troika, and right now it is the Troika’s enforcer.

As Charles Wyplosz recounts, this is not the first time the ECB has chosen to bow to political pressure. There will be some on the left who will say of course - what else do you expect of a central bank? In response, let me go back to my hypothetical example involving Scotland and the Bank of England. I may be wrong, but I think in that case the Bank of England would have supplied unlimited cash to the Scottish banks. I may be naive, but I believe it would have realised that to do anything else was an overtly partisan political act, and recoiled from doing that. Just as I do not think it was inevitable that the Eurozone committed itself to austerity, I also think it was possible that the ECB could have been a more independent central bank. The really interesting question is why it has turned out not to be such a bank.

After Oxi, what next?

A lot of the commentary on Greece fails to see why the Greek No vote changes anything. This view tends to see the stance of the Eurozone group as simply expressing their own voters’ preferences which will not be changed by what happened yesterday. Here is an alternative reading.

It starts from a simple observation. The Troika will get far less of its money back (if any!) if Greece is forced out of the Eurozone. (I say forced out because Greece does not want to leave, so Greek exit is first and foremost an ECB decision: if you think otherwise read Karl Whelan and Matthew Klein and Paul De Grauwe. [1]) That is why creditors are generally weak in negotiations of this kind. Things are different in this case only because the creditors include the ECB, and Greece wants to stay in the Eurozone. The Troika has played this for all it is worth. They were relying (you could say gambling) on the Greek people, one way or another, deciding that they would agree to the Troika’s demands because they feared Greek exit more.

So far this strategy has failed. First they pushed Tsipras further than he could possibly go, hoping perhaps that Syriza would collapse in recriminations. Tsipras’s response was a unifying referendum. They then gambled that Greece would say no, and they lost that too. Tsipras continues to offer the Troika the chance to be more reasonable. He followed the referendum not with triumphalism but by removing his finance minister. This was both a signal - I really want a deal, even though it will in all probability inflict further (unnecessary) pain on Greece - and a lifeline, because the Troika can now say that an important obstacle to a deal has been removed. (An obstacle, because Varoufakis was too open - something politicians and much of the press hate - and too honest about the other side’s lack of economics.)

Now the Troika seem to face a simple choice. Agree a deal and get a little more heat from your political opponents at home for ‘giving in’, or force Greek exit with the risk that you will get a lot more heat when Greece defaults and people realise you have lost all their money. If they are really just interested in getting as much of their money back as possible, it would seem crazy to throw away their best card by forcing Greece out of the Eurozone.

Of course rationality may not prevail, or interests may be rather different. The IMF may continue to be an unhelpful nuisance. (If you think my criticism of their role was harsh, read this from Peter Doyle.) Some within the Troika will be happy to go for Greek exit because they think nationalist sentiment can overcome any kickback from the subsequent Greek default. Others may fear a deal may encourage anti-austerity sentiment in their own indebted countries.

Unfortunately there is a third possibility, which is probably the worst possible outcome. To prevent any loss of face, the Troika may continue to gamble, waiting for days or even weeks, and watch ECB pressure, together with reluctance by Tsipras to introduce a new currency, gradually bring chaos to the Greek economy. Only then will it negotiate, allowing any deal to be portrayed as the result of desperation by the Greek government. In which case, recent European politics will have reached a new all time low.

The Eurozone Scandal

Imagine that it was revealed that 10% of the European Union budget (the money that goes to the EU centre to fund the common agricultural policy and other EU wide projects) had been found to be completely wasted as a result of actions by EU policymakers. By wasted I do not mean spent on things that maybe it should not have been spent on (rich farmers, inefficient farmers, infrastructure projects whose costs exceed benefits etc), but literally money that went up in smoke. Imagine the scandal. Heads would roll, and some might find themselves in jail.

10% of the EU budget is about 0.1% of EU GDP. Yet sums at least ten times that figure are currently being wasted in the Eurozone, as a result of actions by Eurozone policymakers. Here is the latest OECD assessment of output gaps across eleven Eurozone countries, for both 2013 (blue) and 2014 (red).


A negative output gap means that output could be the amount of the gap higher without raising inflation above target. Of course Greece is a nightmare, and things in the other PIIGS are really bad, but the output gap in the Netherlands is around 3%, in France over 2% in 2014, and even in Germany the output gap exceeds 1%. Estimating output gaps is an imprecise science, but gaps of at least this size are consistent with inflation well below target (currently 0.3%). So output could be at least 1% higher across the Eurozone with no ill effects. This is the equivalent of the entire EU budget going up in smoke.

Sometimes negative output gaps are the result of shocks which were not anticipated by policymakers (like the financial crisis). Sometimes they are engineered by policymakers to bring inflation down. It is unfortunate that these things happen, but they always have. However the output gaps we have in the Eurozone today are neither of these. Instead they have been created by policymakers for no good reason. That is why they can be called a scandal.

At this point you might think I’m being unfair. Surely this is all about tight fiscal policy required to bring down government debt. I agree that it is all about fiscal policy, and in particular the crazy fiscal rules imposed within the Eurozone. However where is the urgent need to bring down debt outside the periphery? The OECD estimate that the primary structural budget balance in the Eurozone will be a surplus at around 1% of GDP in 2014 compared to a deficit in the OECD as a whole of just over 1%. So even if you think that we need austerity to bring deficits down rapidly - which I do not - why should policymakers in the Eurozone be doing this so much more quickly than in the UK, US or Japan? To achieve this goal, they are wasting resources on a colossal scale.

If you think anything has changed as a result of Juncker’s ‘E315 bn’ investment plan, you should read this post from Frances Coppola. As she makes clear, there is not a penny of new EU money in this proposal. Instead money earmarked for existing projects is being used to provide insurance to private sector investment (which may or may not happen). There are so many issues with this kind of stimulus. Besides those raised by Frances, there is also the question of how to prevent firms simply getting insurance for schemes they would have undertaken anyway, and how exactly will the Commission select when to allocate its insurance. Those of a neoliberal persuasion who think government is bad at spending its money cannot feel any more comfortable with the government selecting what private sector projects to back. However a scheme like this will come as no surprise to someone like George Monbiot, who thinks states are increasingly being used to serve corporate ends. 

Equally embroiled in this scandal are those making monetary policy decisions at the ECB. Here I can simply defer to an excellent post by Ashoka Mody. In particular he points out why it is misleading to simply look at the ECB’s balance sheet as an indicator of the force of unconventional monetary policy. There is an important difference between creating money to bail out failing banks, as the ECB has done, and creating money to buy bonds to force down long term rates, which is Quantitative Easing (QE). He argues that the “ECB is set to remain—by far—the central bank with the tightest, most conservative monetary policy among the major central banks.” I thought I would quote the following paragraph in full, for reasons that will be clear to regular readers.
“Others play by the rules of the cognitive frame. Thus, despite the serious concerns with the June 5th measures—documented carefully by my Bruegel colleagues—journalists have no interest in asking ECB officials: “What exactly are we waiting for?” The financial markets have no interest in public policy: once the rules are set, they seek opportunities for short-term bets. On July 9th, the International Monetary Fund’s Executive Board somewhat incredulously concluded: “Directors welcomed the exceptional measures recently taken by the European Central Bank (ECB) to address low inflation and strengthen demand, as well as its intention to use further unconventional instruments if necessary.” Belatedly, on November 25th, the OECD became a lone official voice calling for more urgent steps.“
To those who say that QE, as operated by the BoE or Fed, would have limited effectiveness in the Eurozone, I have a lot of sympathy. However there is a relatively simple way of making QE much more effective and predictable, and that is for central banks to create money not to buy financial assets but to transfer directly to citizens, which Friedman called helicopter money. John Muellbauer calls this QE for the people. Conventional QE involves buying a large amount of assets with potential losses for the central bank (if the asset price falls) but uncertain effects on demand. Helicopter money involves small transfers with a certain loss to the central bank but much more predictable positive demand effects. [1]

As an institutional innovation, helicopter money has two major drawbacks in countries with their own central bank. [2] First, why innovate when you can implement exactly the same policy through existing means: in macroeconomic terms helicopter money is equivalent to QE plus tax cuts when you have inflation targeting. Second, a fiscal stimulus in the form of temporary additional government spending is likely to be more predictable in its impact than transfers or tax cuts, because you eliminate the uncertainty caused by how much of the transfer or tax cut will be spent.

But if countercyclical fiscal policy is effectively illegal in the Eurozone, these objections do not apply. QE for the people may have additional legal merits within the Eurozone. The ECB is constrained to some (uncertain) extent in its ability to buy government debt. But, as John Muellbauer suggests, mailing a cheque to every EZ citizen using electoral registers would seem to circumvent these legal difficulties.

One objection to the ECB embarking on ‘QE for the people’ is that it goes well beyond the remit of a central bank. [3] Yet the ECB appears to have no qualms on that score: besides routine references for the need for fiscal consolidation and ‘structural reform’, the letter discussed by Paul De Grauwe here shows the ECB requiring detailed changes to labour market regulations and institutions in Spain. So you have to ask why is it OK for the central bank to override the democratic process in this way, but giving money directly to the people is somehow beyond the pale.

If you think that mailing a cheque to every voter in the Eurozone as a solution to continuing recession sounds too good to be true, then you have just rediscovered why recessions caused by demand deficiency when inflation is below target are such a scandalous waste. It is a problem that can be easily solved, with lots of winners and no losers. The only reason that this is not obvious to more people is that we have created an institutional divorce between monetary and fiscal policy that obscures that truth. It was a divorce that did a reasonable job in steering the economy in normal times, and it might discourage fiscal profligacy when demand is strong, but since 2010 it has led to a scandalous paralysis in the Eurozone.  

  
[1] These losses are notional only, as the central bank is not in the business of making money. They matter only if they compromise the ability of the central bank to do its job of controlling inflation in the future. There are various ways that danger can be avoided, but my point here is that costs to the central bank can arise with any form of QE.

[2] Central banks routinely pass the profits they make (through seigniorage) to governments. So the innovation is that the central bank rather than the government decides how to disperse this money.  

[3] Another objection is that, because the ECB is free to define its own targets, changing the monetary policy framework to target the level of nominal GDP would be a better innovation. I agree this would be a useful innovation. I would argue that it would be better still to allow countercyclical fiscal policy, because only this can deal with country specific shocks. But if, for whatever reason, these changes are ruled out, then a helicopter drop should be implemented. If you are a market monetarist, think of it as an insurance policy.
