Life and work keep having the nasty habit of intruding into this blog, but it feels nice to resume writing, even if just with a short comment.
We learned a few weeks ago that the Bank of Japan has walked one extra step in its attempt to escape lowflation, and that it has committed to overshoot its 2% inflation target. A “credible promise to be irresponsible”, as the FT says quoting Paul Krugman.
This may be a long overdue first step towards a revision of the inflation target, as invoked long ago by Olivier Blanchard, and more recently by Larry Ball. This is all too reasonable: if the equilibrium interest rates are negative, if monetary policy is bound by the zero-or-only-slightly-negative-lower-bound, higher inflation targets would make sense, and 4% is an arbitrary target as legitimate as the current also arbitrary 2% level. Things may be moving, as the subject was evoked, if not discussed, at the recent Central Bankers gathering in Jackson Hole. We’ll see if anything comes out of this.
But the FT also adds an interesting comment to the BoJ move, namely that the more serious risk is a blow to credibility. If it failed to lift the inflation to the 2% target, how can it be credibly believed to overshoot it?
This is a different sort of credibility issue, much more reasonable indeed, than the one we have been used to in the past three decades, linked to the concept of dynamic inconsistency. In plain English the idea that an actor has no incentive to keep prior commitments that go against its own interest, and hence deviates from the initial plan. Credibility was therefore associated to changing incentives over time (typically for policy makers), and invoked to recommend rules over discretion.
Today, eight years into the zero lower bound, we go back to a more intuitive definition of credibility: announcing an objective and not being able to attain it.
The difference between the two definitions of credibility is not anodyne. In the first case, the unwillingness of central banks to behave appropriately can be corrected through the adoption of constraining rules. In the latter, the central bank cannot attain the objective regardless of incentives and constraints, and other strategies need to be put in place.
The other strategy, the reader will not be surprised to learn, is fiscal policy. Monetary dominance is in fact a second tenet of the Consensus from the 1990s that the crisis has wiped out. We used to live in a world in which structural reforms would take care of increasing potential growth, monetary policy would be used to take care of (minor) demand-driven fluctuations, and fiscal policy was in a closet.
This is gone (luckily). Even the large policy making institutions now call for a comprehensive and multi-instrument policy making. The policy mix, a central element of macroeconomics in the pre-rational expectations era, is now back. Even the granitic dichotomy between short (demand driven) and long (supply driven) term, is somewhat rediscussed.
The excessively simplified consensus that dominated macroeconomics for the past thirty years seems to be seriously in trouble; complexity, tradeoffs, coordination, are now the issues discussed in academia and in policy circles. This is good news.
Yesterday the Council decided that Spain and Portugal’s recent efforts to reduce deficit were not enough. This may lead to the two countries being fined, the first time this would happen since the inception of the euro.
It is likely that the fine will be symbolic, or none at all; given the current macroeconomic situation, imposing a further burden on the public finances of
these two any country would be crazy.
Yet, the decision is in my opinion enraging. First, for political reasons: Our
world is crumbling. The level of confidence in political elites is at record low levels, and as the Brexit case shows, this fuels disintegration forces. It is hard not to see a link between these processes and, in Europe, the dismal political and economic performances we managed to put together in the last decade (you are free pick your example, I will pick the refugee crisis (mis) management, and the austerity-induced double-dip recession).
But hey, one might say. We are not here to save the world, we are here to apply the rules. Rules that require fiscal discipline. And of course, both Portugal and Spain have been fiscal sinners since the crisis began (and of course before):
Once we neglect interest payments, on which there is little a government can do besides hoping that they ECB will keep helping, both countries spectacularly reduced their deficit since 2010. And this is true whether we take the headline figures (total deficit, the dashed line), or the structural figures that the Commission cherishes, i.e. deficit net of cyclical components (the solid lines). Looking at this figure one may wonder what they serve to drink during Council (and Commission) meetings, for them to argue that the fiscal effort was insufficient…
What is even more enraging, is that not only this effort was not recognized as remarkable by EU authorities. But what is more, it was harmful for these economies (and for the Eurozone at large).
In the following table I have put side by side the output gaps and fiscal impulse, the best measure of discretionary policy changes1. I have highlighted in green all the years in which the fiscal stance was countercyclical, meaning that a negative (positive) output gap triggered a more expansionary (contractionary) fiscal stance. And in red cases in which the fiscal stance was procyclical, i.e. in which it made matters worse.
|Output Gap and Discretionary Fiscal Policy Stance|

The reader will judge by himself. Just two remarks. linked to the fines put in place. First, the Portuguese fiscal contraction of 2015-2016 is procyclical, as the output gap was and still is negative. On the other hand, Spain has increased its structural deficit, but it had excellent reasons to do so.
One may argue that the table causes problems, because the calculation of the output gap is arbitrary and political in nature. Granted, I could not agree more. So I took headline figures, and compared the “gross” fiscal impulse with the “growth gap”, meaning the difference between the actual growth rate and the 3% level that was assumed to be normal when the Maastricht Treaty was signed (If you are curious about EMU numerology, just look here). This is of course a harsher criterion, as 3% as nowadays become more a mirage than a realistic objective. But hey, if we want to use the rules, we should take them together with their underlying hypotheses. Here is the table:

Lot’s of red, isn’t it? Faced with a structural growth deficit, the EMU at large, as well as Spain and Portugal, has had an excessively restrictive fiscal stance. I know, no real big news here.
To summarize, the decision to fine Portugal and Spain is politically ill-timed and clumsy. And it is economically unwarranted. And yet, here we are, discussing it. My generation grew up thinking that When The World Is Running Down, You Make The Best of What’s Still Around. In Brussels, no matter how bad things get, it is business as usual.
1. The fiscal impulse is computed as the negative of the change in deficit. As such it captures the change in the fiscal stance. Just to make an example, going from a deficit of 1% to a deficit of 5% is more expansionary than going form a deficit of 10% to a deficit of 11%↩.
Last week’s data on EMU growth have triggered quite a bit of comments. I was intrigued by Paul Krugman‘s piece arguing (a) that in per capita terms the EMU performance is not as bad (he uses working age population, I used total population); and (b) that the path of the EMU was similar to that of the US in the first phase of the crisis; and (c) that divergence started only in 2011, due to differences in monetary policy (an impeccable disaster here, much more reactive in the US). Fiscal policy, Krugman argues, was equally contractionary across the ocean.
I pretty much agree that the early policy response to the crisis was similar, and that divergence started only when the global crisis went European, after the Greek elections of October 2009. But I am puzzled (and it does not happen very often) by Krugman’s dismissal of austerity as a factor explaining different performances. True, at first sight, fiscal consolidation kicked in at the same moment in the US and in Europe. I computed the fiscal impulse, using changes in the cyclically adjusted primary deficit. In other words, by taking away the cyclical component, and interest payment, we can obtain the closest possible measure to the discretionary fiscal stance of a government. And here is what it gives:
Krugman is certainly right that austerity was widespread in 2011 and in 2012 (actually more in the US). So what is the problem?
The problem is that fiscal consolidation needs not to be assessed in isolation, but in relation to the environment in which it takes place. First, it started one year earlier in the EMU (look at the bars for 2010). Second, expansion had been more robust in the US in 2008 and in 2009, thus avoiding that the economy slid too much: having been bolder and more effective in 2008-2010, continued fiscal expansion was less necessary in 2011-12.
I remember Krugman arguing at the time that the recovery would have been stronger and faster if the fiscal stance in the US had remained expansionary. I agreed then and I agree now: government support to the economy was withdrawn when the private sector was only partially in condition to take the witness. But to me it is just a question of degree and of timing in reversing a fiscal policy stance that overall had been effective.
I had made the same point back in 2013. Here is, updated from that post, the correlation between public and private expenditure:
|Correlation Between Public and Private Expenditure|
Remember, a positive correlation means that fiscal policy moves together with private expenditure, and fails to act countercyclically. The table tells us that public expenditure in the US was withdrawn only when private expenditure could take the witness, and never was procylclical (it turned neutral in the past 2 years). Europe is a whole different story. Fiscal contraction began when the private sector was not ready to take the witness; the withdrawal of public demand therefore led to a plunge in economic activity and to the double dip recession that the US did not experience. Here is the figure from the same post, also updated:
To sum up: the fiscal stance in the US was appropriate, even if it changed a bit too hastily in 2011. In Europe, it was harmful since 2010.
And monetary policy in all this? It did not help in Europe. I join Krugman in believing that once the economy was comfortably installed in the liquidity trap Mario Draghi’s activism while necessary was (and is) far from sufficient. Being more timely, the Fed played an important role with its aggressive monetary policy, that started precisely in 2012. It supported the expansion of private demand, and minimized the risk of a reversal when the withdrawal of fiscal policy begun. But in both cases I am unsure that monetary policy could have made a difference without fiscal policy. Let’s not forget that a first round of aggressive monetary easing in 2007-2008 had been successful in keeping the financial sector afloat, but not in avoiding the recession. This is why in 2009 most economies launched robust fiscal stimulus plans. I see no reason to believe that, in 2010-2012, more appropriate and timely ECB action would have made a big difference. The problem is fiscal, fiscal, fiscal.
FT Alphaville‘s Matthew Klein goes back to the issue of financial stability and monetary policy. A recent speech of Bank of Canada’s Timothy Lane is the occasion for Klein to reassess monetary policy before the crisis, when policy makers (in particular he refers to Ben Bernanke, but the Fed chair was in good company) dismissed fears of asset price bubbles, thus failing recognize, and to counter, the buildup of the crisis.
What I find interesting in Lane’s speech is the acknowledgement that monetary policy alone is vastly insufficient to attain the many interrelated objectives of today’s policy makers. This in turn calls for reassessing the drift of academic economists (in the 1990s and 2000s) towards a vision of the world in which all policy objectives could be attained by “Maestros“, almighty technocrats skillfully using monetary levers to reach multiple objectives at once.
With a few colleagues we recently challenged the “conventional wisdom” that inflation targeting central banks can effectively attain financial stability as well, simply by “leaning against the wind”. We highlighted that this violation of Timbergen’s principle (“one instrument per policy objective”) is allowed by an analytical trick, a “divine coincidence”, buried within the hypotheses of the standard model. Asessing policy analysis in a framework in which low and stable inflation goes hand in hand with low unemployment and stable asset prices, will lead to conclude that (what a surprise!!) targeting inflation helps attaining all these objectives at once. Our work (among others) shows that price and financial stability exhibit no stable correlation; similarly, the debate on the “return of the Phillips Curve” (if ever it left) shows that a tradeoff usually exists between inflation and unemployment objectives. Thus, in the end, inflation targeting is mostly effective in, well… targeting inflation. There is no magics here. The Consensus buried Timbergen way too soon.
The debate on the effective use of instruments to attain sometimes conflicting objectives is particularly interesting in general and, I argue, relevant for the EMU. As the readers of this blog know, I have been obsessed by the excessive focus of (mainly) European economists and policy makers on monetary policy. Especially in the current situation of liquidity trap, the stubborn refusal to fully deploy fiscal policy can only be explained by ideological anti-Keynesianism.
But as Timothy Lane’s speech suggests, the problem extends beyond the current exceptional circumstances. As normal times will (eventually) resume, we should go back to Timbergen and acknowledge that monetary policy alone cannot cure all ills. Fiscal policy and effective regulation need to be used as aggressively as interest rates and monetary instruments to manage business cycle fluctuation. A trivial and yet often forgotten lesson from the old times.
It is nice to resume blogging after a quite hectic Fall semester. Things do not seem to have gotten better in the meantime…
The EMU policy debate in the past few months kept revolving around monetary policy. Just this morning I read a Financial Times report on the never ending struggle between hawks and doves within the ECB. I am all for continued monetary stimulus. It cannot hurt. But there is only so much monetary policy can do in a liquidity trap. I said it many times in the past (I am in very good company, by the way), and nothing so far proved me wrong.
A useful reminder of how important fiscal policy is, and therefore of how criminal it is to willingly decide to give it up, comes from a recent piece from Blinder and Zandi, who tried to assess what the US GDP trajectory would have been, had the discretionary policy measures implemented since 2008 not been in place. I made a figure of their counterfactual:
It is worth just using their own words:
Without the policy responses of late 2008 and early 2009, we estimate that:
- The peak-to-trough decline in real gross domestic product (GDP), which was barely over 4%, would have been close to a stunning 14%;
- The economy would have contracted for more than three years, more than twice as long as it did;
- More than 17 million jobs would have been lost, about twice the actual number.
- Unemployment would have peaked at just under 16%, rather than the actual 10%;
- The budget deficit would have grown to more than 20 percent of GDP, about double its actual peak of 10 percent, topping off at $2.8 trillion in fiscal 2011.
- Today’s economy might be far weaker than it is — with real GDP in the second quarter of 2015 about $800 billion lower than its actual level, 3.6 million fewer jobs, and unemployment at a still-dizzying 7.6%.
We estimate that, due to the fiscal and financial responses of policymakers (the latter of which includes the Federal Reserve), real GDP was 16.3% higher in 2011 than it would have been. Unemployment was almost seven percentage points lower that year than it would have been, with about 10 million more jobs.
The conclusion I draw is unequivocal: Blinder and Zandi give yet another proof that what made the current recession different from the tragedy of the 1930s it the swift and bold policy reaction.
This of course nothing new. But unfortunately, it sounds completely heretic in European policy circles. In my latest post (internet ages ago) I noticed that how little Mario Draghi’s position on fiscal matters differed from Angela Merkel’s, and in general from the European pre-crisis consensus.
The reader will have noticed that in the figure above I also drew EMU12 real GDP. It did not fall as much as the US no-policy counterfactual (among other things because exports kept us afloat thanks to…the US recovery). But we are today stuck in a semi-permanent state of stagnant growth. EMU12 GDP is today at the same level as the level the US would have had, had their policies been completely inertial. Once again, a visual aid:
I already showed this figure in the past. On the x-axis you have the output gap, i.e. a measure of how deep in a recession the economy is. On the y-axis you have he fiscal impulse, i.e. a measure of discretionary fiscal policy (net of interest payment and of cyclical adjustment of government deficit). A well functioning fiscal policy would result in a negative correlation: If the economy goes down (negative output gap), fiscal policy is expansionary (positive fiscal impulse). This is what actually happened in 2008-2009 (red series). But then as we know European policy makers succumbed to the fairy tale of expansionary fiscal consolidations, and fiscal policy turned pro-cyclical (yellow series). A persisting output gap was met with fiscal consolidation (improvement in structural fiscal balance).
Overall, policy was neutral. This is consistent with the Berlin View, that fears discretionary policies as if they were the plague. And explains much of our dismal performance. The fact that we are close to Blinder and Zandi’s “no-policy” scenario is no coincidence at all. Our policy makers should look at their blue line for the US, and realize that we could be around there too, if only they were less stubbornly ideological.
We are becoming accustomed to European policy makers’ schizophrenia, so when yesterday during his press conference Mario Draghi mentioned the consolidating recovery while announcing further easing in December, nobody winced. Draghi’s call for expansionary fiscal policies was instead noticed, and appreciated. I suggest some caution. Let’s look at Draghi’s words:
Fiscal policies should support the economic recovery, while remaining in compliance with the EU’s fiscal rules. Full and consistent implementation of the Stability and Growth Pact is crucial for confidence in our fiscal framework. At the same time, all countries should strive for a growth-friendly composition of fiscal policies.
During the Q&A, the first question was on precisely this point:
Question: If I could ask you to develop the last point that you made. Governor Nowotny last week said that monetary policy may be coming up to its limits and perhaps it was up to fiscal policy to loosen a little bit to provide a bit of accommodation. Could you share your thoughts on this and perhaps even touch on the Italian budget?
(Here is the link to Austrian Central Bank Governor Nowotny making a strong statement in favour of expansionary fiscal policy). Draghi simply did not answer on fiscal policy (nor on the Italian budget, by the way). The quote is long but worth reading
Draghi: On the first issue, I’m really commenting only on monetary policy, and as we said in the last part of the introductory statement, monetary policy shouldn’t be the only game in town, but this can be viewed in a variety of ways, one of which is the way in which our colleague actually explored in examining the situation, but there are other ways. Like, for example, as we’ve said several times, the structural reforms are essential. Monetary policy is focused on maintaining price stability over the medium term, and its accommodative monetary stance supports economic activity. However, in order to reap the full benefits of our monetary policy measures, other policy areas must contribute decisively. So here we stress the high structural unemployment and the low potential output growth in the euro area as the main situations which we have to address. The ongoing cyclical recovery should be supported by effective structural policies. But there may be other points of view on this. The point is that monetary policy can support and is actually supporting a cyclical economic recovery. We have to address also the structural components of this recovery, so that we can actually move from a cyclical recovery to a structural recovery. Let’s not forget that even before the financial crisis, unemployment has been traditionally very high in the euro area and many of the structural weaknesses have been there before.
Carefully avoiding to mention fiscal policy, when answering a question on fiscal policy, speaks for itself. In fact, saying that “Fiscal policies should support the economic recovery, while remaining in compliance with the EU’s fiscal rules” and putting forward for the n-th time the confidence fairy, amounts to a substantial approval of the policies followed by EMU countries so far. We should stop fooling ourselves: Within the existing rules there is no margin for a meaningful fiscal expansion of the kind invoked by Governor Nowotny. If we look at headline deficit, forecast to be at 2% in 2015, the Maastricht limits leave room for a global fiscal expansion of 1% of GDP, decent but not a game changer (without mentioning the fiscal space of individual countries, very unevenly distributed). And if we look at the main indicator of fiscal effort put forward by the fiscal compact, the cyclical adjusted deficit, the eurozone as a whole should keep its fiscal consolidation effort going, to bring the deficit down from its current level of 0.9% of GDP to the target of 0.5%.
It is no surprise then that the new Italian budget (on which Mario Draghi carefully avoided to comment) is hailed (or decried) as expansionary simply because it slows a little (and just a little) the pace of fiscal consolidation. Within the rules forcefully defended by Draghi, this is the best countries can do. As a side note, I blame the Italian (and the French) government for deciding to play within the existing framework. Bargaining a decimal of deficit here and there will not lift our economies out of their disappointing growth; and more importantly, on a longer term perspective, it will not help advance the debate on the appropriate governance of the eurozone.
In spite of widespread recognition that aggregate demand is too low, Mario Draghi did not move an inch from his previous beliefs: the key for growth is structural reforms, and structural reforms alone. He keeps embracing the Berlin View. The only substantial difference between Draghi and ECB hawks is his belief that, in the current cyclical position, structural reforms should be eased by accommodating monetary policy. This is the only rationale for QE. Is this enough to define him a dove?
