I was asked to write a piece on whether we should continue to study the EMU (my answer is yes. In case you wonder, this is called vested interest). One section of it can be a stand-alone blog post: Here it is, with just a few edits:
While in the late 1980s the consensus among economists and policy makers was that the EMU was not an optimal currency area (De Grauwe, 2006), the choice was made to proceed with the single currency for two essentially opposed reasons: The first, stemming from the Berlin-Brussels Consensus, saw monetary integration, together with the establishment of institutions limiting fiscal and monetary policy activism, as an incentive for pursuing structural reforms and converging towards market efficiency: as the role of macroeconomic management was believed to be limited, giving up monetary policy would impose negligible costs to countries while forcing them, through competition, to remove growth-stifling obstacles to markets.
Another group of academics and policy makers, while not necessarily subscribing to the Consensus, highlighted the political economy of the single currency: Adopting the euro in a non-optimal currency area would have created the incentives for completing it with a political union: a federation, endowed with a common fiscal policy and capable of implementing the fiscal transfers that are required to avoid divergence. In other words a non-optimal euro was seen as just an intermediate step towards a real United States of Europe. A key argument of the proponents of a federal Europe was, and still is, that fiscal transfers seem unavoidable to ensure economic convergence. A seminal paper by Sala-i-Martin and Sachs (1991) shows that even in the United States, where market flexibility is substantially larger than in the EMU, transfers from booming states to states in crisis account for almost 50% of the reaction to asymmetric shocks.
It is interesting to notice how the hopes of both views were dashed by subsequent events. As the theory of optimal currency areas correctly predicted, the inception of the euro without sufficiently strong correction mechanisms, triggered a divergence between a core, characterized by excess savings and export-led growth, and a periphery that sustained the Eurozone growth through debt-driven (public and private) consumption and investment.
Even before the crisis the federal project failed to make it into the political agenda. The euro came to be seen by the political elites not, as the federalists hoped, as an intermediate step towards closer integration, but rather as the endpoint of the process initiated by Jean Monnet and Robert Schuman in 1950. The crisis further deepened economic divergence and recrimination, highlighting national self-interest as the driving force of policy makers, and making solidarity an empty word. As we write, the Greek crisis management, the refugee emergency, the centrifugal forces shaking Europe, are seen as a potential threat to the Union, rather than a push for further integration as it happened in the past (Rachman, 2015).
The Consensus partisans won the policy debate. The EMU institutions, banning discretionary policy, reflect their intellectual framework; and the policies followed (more or less willingly) by EMU countries, especially since the crisis, are the logical consequences of the consensus: austerity and structural reforms aimed at increasing competitiveness and reducing the weight of the State in the economy. But while they can rejoice of their victory, Consensus proponents have to deal with the failure of their policies: five years of Berlin View therapy has nearly killed the patient. Peripheral countries’ debt is still unsustainable, growth is nowhere to be seen (including in successful Germany), and social hardship is reaching unbearable levels (Kentikelenis et al., 2014). Coupling austerity with reforms proved to be self-defeating, as the short term recessionary impact on the economy was much larger than expected (Blanchard and Leigh, 2013), and as a consequence the long run benefits failed to materialize (Eggertsson et al., 2014). It is then no surprise that in spite of austerity and reforms, divergence between the core and the periphery of the Eurozone is even larger today than it was in 2007.
The dire state of the Eurozone economy is in some sense the revenge of optimal currency areas theory, with a twist. It appears evident today, but it was clear two decades ago, that market flexibility alone would never suffice to ensure convergence (rather the opposite), so that the Consensus faces a potentially fatal challenge. On the other hand, the federalist project, that was already faltering, seems to have received a fatal blow from the crisis.
The conclusion I draw from these somewhat trivial considerations is that the EMU is walking a fine line. If the federalist project is dead, and if Consensus policies are killing the EMU, what have we left, besides a dissolution of the euro?
I conclude the paper by arguing that two pillars of a new EMU governance/policy are necessary (neither of them in isolation would suffice):
- Putting in place any possible surrogate of fiscal transfers, like for example a EU wide unemployment benefit, making sure that it is designed to be politically feasible (i.e. no country is net contributor on average), eurobonds, etc.
- Scrapping the Consensus together with its foundation, the efficient market hypothesis, and head towards real, flexible coordination of (imperfect) macroeconomic policies in order to deal with (imperfect) markets. Government by the rules only works in the ideal neoclassical world.
I know, more easily said than done. But I see no other possibility.
Jared Bernstein has a very interesting piece on the lessons we
(did not) learn from the great crisis. He basically makes two points:
First, the attitude towards lenders, while somewhat schizophrenic (Bear Sterns, up; Lehman, down. Why? We still don’t know), was forgiving to say the least. in his words, ” Borrowers get austerity, joblessness, and poverty. Lenders get bailouts when credit is scarce and bribes not to lend when it’s too plentiful”. He then argues that both letting lenders fail and bailing them out has large costs, that should be avoided ex ante through better regulation (and we are not there, yet).
Bernstein is perfectly right, but he neglects mentioning a third option, that was advocated at the time, for example by Joe Stiglitz: temporary bank nationalization. The Swedish experience of 1992 proves, according to many (1, 2), that this would have been as effective, while the cost for the taxpayer would have been greatly reduced if not completely eliminated. Public control over the main financial institutions would have guaranteed that the necessary healing could happen without the rents and bonuses that actually went to the very same people who had caused the trouble in the first place. Temporary nationalization, in other words, would have avoided the “Heads I win Tail you lose” feature of financial sector bailouts.
The second point Bernstein makes is that regardless of the strategy chosen to save the financial sector, fiscal policy should have been much more aggressive in fighting the downturn. A quote, again:
But here’s what I do know. Neither bailouts nor allowing insolvent banks to fail will work if, when private sector demand is subsequently tanking, we undercut the use of fiscal policy to make up the difference. In this regard, the clearest lesson of Lehman is not simply that we must regulate financial markets, which is true, nor is it that we must always preserve private credit flows by fully bailing out irresponsible lenders, which contributes to inequality and economic unfairness.
It’s that it takes both monetary and fiscal policy working together to get back to full employment. Restored credit flows alone won’t get people back to work. That’s pure supply-side thinking.
Well, he says it all. What drives me nuts, is that the he complains about the US, THE US, where the Fed showed incredible activism, where the Obama administration voted and implemented a huge stimulus package (the American Recovery and Reinvestment Act) just weeks after been sworn in office, while it took us 7 years, to decide to adopt a cumbersome investment plan that will make little or no difference.
Without even mentioning the fact that the whole Greek crisis, since 2010, has been managed with an eye to (mostly German and French) lenders’ needs, rather than to the well-being of European (and in particular Greek) taxpayers.
I really would like to know what would Bernstein say, were he to comment the EMU lessons from the crisis…
So, Mario Draghi is disappointed by eurozone growth, and is ready to step up the ECB quantitative easing program. The monetary expansion apparently is not working out as planned.
Big surprise. I am afraid some people do not have access to Wikipedia. If they had, they would read, under “liquidity trap“, the following:
A liquidity trap is a situation, described in Keynesian economics, in which injections of cash into the private banking system by a central bank fail to decrease interest rates and hence make monetary policy ineffective. A liquidity trap is caused when people hoard cash because they expect an adverse event such as deflation, insufficient aggregate demand, or war.
In a liquidity trap the propensity to hoard of the private sector becomes virtually unlimited, so that monetary policy (be it conventional or unconventional) loses traction. It is true that the age of great moderation, and three decades of almighty central bankers had made the concept fade into oblivion. But, since 2008 we were forced to reconsider the effectiveness of monetary policy at the so-called zero lower bound.
Or at least we should have…
So, had policy makers taken the time to look at the history of the great depression, or at least to open the Wikipedia entry, they should have learnt that when monetary policy loses traction, the witness in lifting the economy out of the recession, needs to be taken by fiscal policy. In a liquidity trap the winner is fiscal policy. Or at least it should be. Here is a measure of the fiscal stance, computed as the change in government balance once we exclude cyclical components and interest payments.
The vast majority of E
MU countries undertook a strong fiscal tightening, regardless of the actual health of their public finances. This generalized austerity, an offspring of the Berlin View, led to our double dip recession, and to further divergence in the eurozone, that would have needed coordinated, not synchronized fiscal policies. Well done guys…
And yet, Mario Draghi is surprised by the impact of QE.
Yesterday I commented on the intriguing box in which the IMF staff challenges one of the tenets of the Washington consensus, the link between labour market reform and economic performance.
But the IMF is not new to these reassessments. In fact over the past three years research coming from the fund has increasingly challenged the orthodoxy that still shapes European policy making:
- First, there was the widely discussed mea culpa in the October 2012 World Economic Outlook, when the IMF staff basically disavowed their own previous estimates of the size of multipliers, and in doing so they certified that austerity could not, and would not work (of course this led EU leaders to immediately rush to do more of the same).
- Then, the Fund tackled the issue of income inequality, and broke another taboo, i.e. the dichotomy between fairness and efficiency. Turns out that unequal societies tend to perform less well, and IMF staff research reached the same conclusion. And once the gates opened, it did not stop. The paper by Berg and Ostry was widely read. Then we had Ball et al on the distributional effects of fiscal consolidation (surprise, it increases inequality). Another paper investigated the channels for this link, highlighting how consolidation leads to increased inequality mostly via unemployment. And just last week I assisted to a presentation by IMF economists showing how austerity and inequality are positively related with political instability.
- On labour markets, before yesterday’s box 3.5, the Fund had disseminated research linking increased inequality with the decline in unionization.
- Then, of course, the “public Investment is a free lunch” chapter three of the World Economic Outlook, in the fall 2014.
- In between, they demolished another building block of the Washington Consensus: free capital movements may sometimes be destabilizing…
These results are not surprising per se. All of these issues are highly controversial, so it is obvious that research does not find unequivocal support for a particular view. All the more so if that view, like the Washington Consensus, is pretty much an ideological construction. Yet, the fact that research coming from the center of the empire acknowledges that the world is complex, and interactions among agents goes well beyond the working of efficient markets, is in my opinion quite something.
What does this mass (yes, now it can be called a mass) of work tells us? Three things, I would say. First, fiscal policy is back. it really is. The Washington Consensus does not exist anymore, at least in Washington. Be it because the multipliers are large, or because it has an impact on income distribution (and on economic efficiency); or again because public investment boosts growth, fiscal policy has a role to play both in dampening business cycle fluctuations and in facilitating stable and balanced long term growth. The fact that a large institution like the IMF has lent its support to this revival of consideration for fiscal policy, makes me hope that discussions about macroeconomic policy will be less ideological, even once the crisis will have passed.
The second thing I learn is that the IMF research department proves to be populated of true researchers, who continuously challenge and test their own views, and are not afraid of u-turns if their own research dictates them. I am sure it has always been the case. What is different from the past is that now they have a chief economist who seems more interested in understanding where the world goes than in preaching a doctrine.
The third remark is more problematic. If I write a paper saying that austerity will not be costly because multipliers are 0.5, and 2 years later retract my previous statement and argue that austerity is in fact self defeating, the impact on the world is zero. If the IMF does the same, during the two years huge suffering will be needlessly inflicted to masses of people. This poses a problem, as research by definition may be falsified. In the past an institution like the IMF would never have admitted a mistake. And we certainly do not want to go back there. Today they do admit the mistakes, but the suffering remains. The only way out to this problem is that the “new” IMF should learn to be cautious in its policy prescriptions, and always remember that any policy recommendation is bound to be sooner or later proven inappropriate by new data and research. We don’t live in a black and white world. Adopting a more prudent stance in dictating policies would be wise (in Brussels as well, it goes without saying). And of course, the disconnect between the army and the general is also a problem.
Simon Wren-Lewis has an interesting piece on structural deficits. He has issues with Pisani-Ferry’s plea for more stable structural deficit targets for EU countries. While Pisani-Ferry has a point in invoking more certainty for EU government action, Wren-Lewis argues, rightly so, that stable targets risk creating straitjackets for countries, and that the problem is mostly in the excessively short time horizon of structural deficit targets.
The fact that both Pisani and Wren-Lewis have a point highlights what is in my opinion a structural flaw of EU fiscal governance, namely its reliance on the slippery concept of structural government deficit.
To explain this simply, the idea underlying structural deficit targets is that not all deficit were created equal. if the government runs a deficit because of adverse cyclical conditions (low growth yields lower tax revenues and larger welfare payements), this deficit is “healthy” because it supports economic activity, and bound to disappear when the economy recovers. As such, governments should not be required to target cyclical deficit, but only the structural (or cyclically adjusted) deficit, which is precisely the deficit “cleaned” of its cyclical component.
The EU fiscal rule, the Stability Pact and its hardened Fiscal Compact extension, recognizes this distinction, and imposes that governments balance their budget over the cycle, which is yet another definition of structural deficit. This may seem a sensible approach, recognizing, as I just said, that not all deficits were created equal. But in fact sensible it is not.
The problem lies precisely in the word “cleaned” I used above . How do we clean headline deficit from its cyclical component, to compute the structural deficit that should be targeted by governments? This is how we should do it: We compute “potential output”, i.e. the capacity of production of the economy. From that we can obtain the output gap, i.e. the distance of actual output from its potential level; finally, by applying an estimate of how the deficit responds to the output gap, we can clean headline deficit from its cyclical component. Simple, right? Yes, in theory. In practice, we have no way to do it in a sufficiently precise way.
Any meaningful analysis of cyclical developments, of medium term growth prospects or of the stance of fiscal and monetary policies are all predicated on either an implicit or explicit assumption concerning the rate of potential output growth. Given the importance of the concept, the measurement of potential output is the subject of contentious and sustained research interest.
All the available methods have “pros” and “cons” and none can unequivocally be declared better than the alternatives in all cases. Thus, what matters is to have a method adapted to the problem under analysis, with well defined limits and, in international comparisons, one that deals identically with all countries. (emphasis is mine)
There is nothing wrong with recognizing that potential output estimates are “contentious”. Contrary to what some Talebans persist to argue, economics is a social science, subject to all the uncertainties, mismeasurements, and ambiguities that are inherently linked to human and social interactions.
Where we have a problem is in using a contentious concept as the foundation for rules in which a zeropointsomething deviation from the target may lead to sanctions and public disapproval by the EU community, with all the potential financial market disruptions associated with it.
This makes the rule non credible, because the contentious estimate may be questioned. More importantly, it leads to what Wren-Lewis fears: countries imposing harsh sacrifices to their people that may turn out to be unwarranted when the estimate is revised.
I am not clear about what fiscal rule we should have in the EU. I actually am not even convinced that we really would need one. What is certain is that two necessary conditions for any rule to be effective, credible, and reasonable are that it is not short -termist (I rejoin Wren-Lewis), and that it is based on indicators that are quantitatively as precise as possible.
The current rule fails on both ground (and don’t get me started on how crazily complicated and arbitrary it grew over time). EU fiscal governance remains founded on sand. And of course, a serious debate on its reform is nowhere to be seen in European policy circles.
A quick note on the US and the Fed. Pressure for rate rises never really stopped, but lately it has intensified. Today I read on the FT that James Bullard, Saint Louis Fed head, urges Janet Yellen to raise rates as soon as possible, to avoid “devastating asset bubbles”. Just a few months ago we learned that QE was dangerous because, once again through asset price inflation, it led to increasing inequality. Not to mention the inflationistas (thanks PK for the great name!) who since 2009 have been predicting Weimar-type inflation because of irresponsible Fed behaviour (a very similar pattern can be found in the EMU). Let’s play the game, for the sake of argument. After all, asset price inflation, and distortions in general are not unlikely in the current environment. So let’s assume that the Fed suddenly were convinced by its critics, and turned its policy stance to restrictive (hopefully this is just a thought experiment). I have two related questions to rate-raisers (the same two questions apply to QE opponents in the EMU):
- Do they think that private expenditure is healthy enough to grow and to sustain economic activity without the oxygen tent of monetary policy?
- If not, would they be willing to accept that monetary restriction is accompanied by a fiscal expansion?
I am afraid we all know the answer, at least to the second of these questions. Just yesterday, on Italian daily Il Corriere della Sera, Alberto Alesina and Francesco Giavazzi called for public expenditure cuts, invoking the confidence fairy and expansionary austerity (yes, you have read well. Check for yourself if you understand Italian. And check the date, it is 2015, not 2007) What Fed (and ECB) bashers tend to forget, in conclusion, is that central bankers are at the center of the stage, reluctantly, because they have to fill the void left, for different reasons, by fiscal policy. Look at the fiscal stance for the US: Fiscal impulse, the discretionary stance of the US government, was positive only in 2008-2009, and has been restrictive since then. In other words, while the US were experiencing the worse crisis since the 1930s, while recovery was sluggish and jobless, the US government was pushing the brake. We all know why: political blockage and systematic boycott, by one side of Congress, of each and every one of the measures proposed by the administration (that was a bit too timid, if I may say so). Whatever the reasons, the fact remains that fiscal policy was of very limited help during the crisis. What do Fed bashers have to say about this? What would have happened if, faced with procyclical fiscal policy, the Fed had not stepped in with QE? I am afraid their answer would once again turn around confidence fairies… The EMU is pretty much in the same situation. The following figure shows the cumulative fiscal impulse since 2008 for a number of countries: The figure speaks for itself. With the exception of Japan (thanks Abenomics!) governments overall acted as brakes for the economy (Alesina and Giavazzi should look at the data for Italy, by the way). Central banks had to act in the thunderous silence of fiscal policy. So I repeat my question once again: who would be willing to exchange a normalization of monetary policy with a radical change in the fiscal stance? To conclude, yes, monetary policy has been very proactive (even Mario Draghi’s ECB); yes, this led us in unchartered lands, and we do not fully grasp what will be the long term effects of QEs and unconventional monetary policies; yes, some distortions are potentially dangerous. But central bankers had no choice. We are in a liquidity trap, and the main tool to be used should be fiscal policy. Monetary policy could and should be normalized, if only fiscal policy would finally take the witness, and the burden to lift the economy out of its woes; if fiscal policy finally tackled the increasing inequality that is choking the economy. If fiscal policy did its job, in other words.
I don’t know why, but I have the feeling that Janet Yellen and Mario Draghi would not completely disagree.
It seems that we finally have our Bazooka. Quantitative Easing will be put in place; its size is slightly larger than expected (€60bn a month), and Mario Draghi, once again, seems to have gotten what he wanted in his confrontation with hawks within and outside the ECB (I won’t comment on risk sharing. I am far from clear about the consequences of that).
And yet, something is just not right. I am afraid that QE will end up like LTRO and all the other liquidity injections the ECB performed in the past. What bothers me is not the shape of the program (given the political constraints, one could hardly imagine something more radical), but Draghi’s press conference. Here is a quote from the introductory statement:
Monetary policy is focused on maintaining price stability over the medium term and its accommodative stance contributes to supporting economic activity. However, in order to increase investment activity, boost job creation and raise productivity growth, other policy areas need to contribute decisively. In particular, the determined implementation of product and labour market reforms as well as actions to improve the business environment for firms needs to gain momentum in several countries. It is crucial that structural reforms be implemented swiftly, credibly and effectively as this will not only increase the future sustainable growth of the euro area, but will also raise expectations of higher incomes and encourage firms to increase investment today and bring forward the economic recovery. Fiscal policies should support the economic recovery, while ensuring debt sustainability in compliance with the Stability and Growth Pact, which remains the anchor for confidence. All countries should use the available scope for a more growth-friendly composition of fiscal policies.
And here the answer to a question, even more explicit:
What monetary policy can do is to create the basis for growth, but for growth to pick up, you need investment. For investment you need confidence, and for confidence you need structural reforms. The ECB has taken a further, very expansionary measure today, but it’s now up to the governments to implement these structural reforms, and the more they do, the more effective will be our monetary policy. That’s absolutely essential, as well as the fiscal consolidation side. So structural reforms is one thing, budget and fiscal consolidation is a different issue. It’s very important to have in place a so-called growth-friendly fiscal consolidation for confidence strengthening. This combined with a monetary policy which is very expansionary, which has been and is even more so after our decisions today, is actually the optimal combination. But for this now, we need the actions by the governments, and we need the action also by the Commission, both in its overseeing role of fiscal policies and in its implementing the investment plan, which was launched by the President of the Commission, which was certainly welcome at the time, now has to be implemented with speed. Speed is of the essence.
The message could not be any clearer: Draghi expects the QE program to impact economic activity through private spending. What we have here is the nt-th comeback of the confidence fairy: accommodative monetary policy, structural reforms and fiscal consolidation, will cause a private expenditure surge (“[..] but will also raise expectations of higher incomes and encourage firms to increase investment today and bring forward the economic recovery“). We have been told this many times since 2010.
Unfortunately, it did not work like this, and I am afraid it will not this time either. The private sector signals in all surveys available that it is not ready to resume spending. If governments are not given the possibility to spend more, most of the liquidity injected into the system will remain idle, exactly as it was the case for the (T)LTRO.
The concept of countercyclical policies is so trivial as to become commonsensical: Governments should step in when markets step out, and withdraw when markets step in again. Filling the gap will actually sustain economic activity, and crowd-in private expenditure; more so, much more so, than filling the pockets of agents with money they are not willing to spend. This is the essence of Keynes. Since 2010 in Europe governments rushed to the exit together with markets; joint deleveraging meant depressed economy. How could one be surprised that confidence does not return?
I would like to add that invoking more active fiscal policy within the limits of the Treaties has the flavour of a bad joke. Just so as we understand what we are talking about, the EMU 18 in 2014 had a deficit-to-GDP ratio of 2.6% (preliminary estimates by the Commission, Ameco database); this means that to remain within the Treaty a fiscal stimulus would have to be limited to 0.4% of GDP. How large would the multiplier have to be, for this to lift the eurozone economy out of deflation? Even the most ardent Keynesian would have a hard time claiming that!! And also, so as we don’t forget, at less than 95% of GDP EMU, Gross public debt can hardly be seen as an obstacle to a serious fiscal stimulus. Even in the short run.
The point I want to make is that QE is all very good, but European governments need to be put in condition to spend the money. It is tiring to repeat the same thing again and again: in a liquidity trap monetary policy can only be a companion to the main tool that could be used by policy makers: fiscal policy.
But in Europe, bad economic policy is today considered a virtue.
