Update (10/27): Comments rightly pointed to different deflators for the two series. I added a figure to account for this (thanks!)
The first thing that came to my mind is that we’d need a robust and sustained increase, in order to make up for lost ground, so I looked for longer time series in Fred, and here is what I got
This yet another (and hardly original) proof of the regime change that occurred in the 1970s, well documented by Piketty. Before then, US productivity (output per hour) and compensation per hour roughly grew together. Since the 1970s, the picture is brutally different, and widely discussed by people who are orders of magnitude more competent than me.
[Part added 10/27: Following comments to the original post, I added real compensation defled with the GDP deflator. While this does not account for purchasing power changes, it is more directly comparable with real output. Here is the result:
The commentators were right, the divergence starts somewhat later, in the early 1980s. This makes it less of a Piketty moment, while leaving the broad picture unchanged.]
Next, I tried to ask whether it is better for wage earners, in this generally gloomy picture, to be in a recession or in a boom. I computed the difference between productivity (output per hour) and wages (compensation per hour), and averaged it for NBER recession and expansion periods (subperiods are totally arbitrary. i wanted the last boom and bust to be in a single row). Here is the table:
|Yearly Average Difference Between Changes in Productivity and in Wages|
|In Recessions||In Expansions||Overall||% of Quarters in Recession|
|Source: Fred (my calculations)|
|Compensation: Nonfarm Business Sector, Real Compensation Per Hour|
|Productivity: Nonfarm Business Sector, Real Output Per Hour|
No surprise, once again, and nothing that was not said before. The economy grows, wage earners gain less than others; the economy slumps, wage earners lose more than others. As I said a while ago, regardless of the weather stones keep raining. And it rained particularly hard in the 2000s. No surprise that inequality became an issue at the outset of the crisis…
There is nevertheless a difference between recessions and expansions, as the spread with productivity growth seems larger in the former. So in some sense, the tide lifts all boats. It is just that some are lifted more than others.
Ah, of course Real Compensation Per Hour embeds all wages, including bonuses and stuff. Here is a comparison between median wage,compensation per hour, and productivity, going as far back as data allow.
I don’t think this needs any comment.
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|
|Output Gap||Fiscal Impulse||Output Gap||Fiscal Impulse||Output Gap||Fiscal Impulse|
|Source: Datastream – AMECO Database|
|Note: Fiscal Impulse computed as change of cyclically adjusted deficit net of interest|
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:
|Growth Gap and Overall Fiscal Policy Stance|
|Growth Gap to 3%||Fiscal Impulse||Growth Gap to 3%||Fiscal Impulse||Growth Gap to 3%||Fiscal Impulse|
|Source: Datastream – AMECO Database|
|Note: Fiscal Impulse computed as change of government deficit net of interest|
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%↩.
Much has been said, already, and even more will be said in the coming hours/days/weeks/months/years, on Brexit. I have little to add. So here is what I see as a series of notes to self. For those who are already tired of reading pages and pages, I can summarize what follows in a sentence: We should focus more on policies than on institutions
- The long lasting skepticism about the EU that always permeated British society across the board, has eventually been compounded by the recent dreadful performance of EU member states in managing the crises that have hit our communities. A sparse and incomplete list would include the stubborn insistence on the wrong policy mix (austerity cum reforms) which yielded a double-dip recession that no other large economy experienced in the past decade; the obsession with debt and deficits when the economy was in desperate need for public support to aggregate demand; the despise of democracy shown when dealing with the Greek referendum last summer; the slow moving ECB that only took action years (not weeks, years) after the other central banks; the bullying of small countries in crisis, in negotiations that really were not one, but rather a take-it-or-leave-it; and finally, maybe the mother of all policy mistakes, the cynical and illogical management of refugees crisis. Show that to voters who always were half in and half out, and it is no surprise that they want to walk away.
- The EU has been made the scapegoat for choices of the UK government, that was reelected just a few months ago. Osborne and Cameron embraced austerity and government downsizing wholeheartedly, they did not need the EU for this. If it is these policies that the British voters wanted to sanction, then they cast their vote in the wrong elections.
- Which brings me to those who today happily see Brexit as the beginning of the end of the EU, and with it of austerity and reforms. I am afraid they are delusional here. Neoliberal policies existed before the EU, and they will exist after. They are the making of governments (and academics), that will not vanish together with the EU. Rather the contrary. Let’s not forget that one of the main selling points of the Leave camp has been that EU regulation chokes UK businesses. If you want to scrap neoliberal policies, rather than fighting the EU, that is a mere vehicle, you should fight the governments that propose them . Remind me of that old story about looking at the finger rather than at the moon?
- My feeling is, and I am afraid to be proven right, that the disintegration of the EU would make it harder to protect social justice, workers’ right, the welfare state. Small countries would be even more exposed than the EU as a whole to competitive pressure from the rest of the world. And competitive pressure in the past never turned out to work in favour of labour and wages.
- The fact that neoliberalism has very little to do with the EU is proven by the rise of populism well beyond our borders. The global problem is an increasingly dysfunctional economic system. If you kill growth and prosperity, if you increase the social divide, if you boost inequality, then it is no surprise that the first guy saying “life was better before” is given a chance by voters. In normal times, a somebody like Farage (or Le Pen, or Trump, or Salvini) would have very little traction with the voters. Today they give the cards of the political game. And in Europe the game is made easier by the existence of a perfect scapegoat, that is far and immaterial, the EU.
- This is why I would also resist the temptation to blame the voters as irresponsible, conservative, irrational, nostalgic, uneducated. The age or education divide of the Brexit referendum is all over the web. But I see them both as proxies for the really relevant divide, which is between the winners and the losers of the past few decades. The same divide that emerges in the US (where paradoxically the losers put faith in the typical winner), and in all the other EU countries.
- How to win the hearths and minds of the losers? How to claim their confidence back? Should that not be by definition the essence of a progressive agenda? The way out is to end harmful policies, and to re-transform the EU into a symbol of social progress. Easier said than done, of course; but I see no alternative. What I have been writing in this blog since 2011 tries to explore possible ways to do so. We should stop looking at institutions (the Stability Pact, the euro), and focus on policies, fighting the wrong ones and supporting the right ones. EU institutions are certainly dysfunctional. They are certainly biased towards excessive reliance on market mechanisms (that prove over and over again how far they are from the academic ideal of perfect efficiency). But once again, they can be twisted, and even changed, if only a political will to do so emerges. In a sentence, even within the current institutional framework, if there was a clear political consensus towards abandoning austerity, we could do so. The problem, I will never get tired of repeating it, is not the Stability Pact. The problem are governments that fail to put it on hold or even to change it.
- (This is just a sharper restatement of 4). We should stop fighting the EU (or the euro) as the cause of our troubles. We should spot the forces that within each country fight for a radical change in policies, and work to give them a majority. If we do so, the EU will cease to be a problem, and will hopefully become again a force of progress. If we don’t, no Brexit or XXxit will bring to us prosperity. Rather the contrary.
- Of course I am thinking in particular of large countries. The Syriza experience in Greece proves that “rejection of austerity in a single country”, especially if it is small and in trouble, cannot work. A new paradigm for policy making should emerge in France, in Germany, in Italy. That would allow a meaningful debate at the European scale.
- All this said, given how self-referential are our elites, how self-indulgent, how superficial in their approach to policy, my “gloominess” is doomed to persist.
Readers of this blog know that I have been skeptical on the ECB quantitative easing program.
I said many times that the eurozone economy is in a liquidity trap, and that making credit cheaper and more abundant would not be a game changer. Better than nothing, (especially for its impact on the exchange rate, the untold objective of the ECB), but certainly not a game changer.
The reason, is quite obvious. No matter how cheap credit is, if there is no demand for it from consumers and firms, the huge liquidity injections of the ECB will end up inflating some asset bubble. Trying to boost economic activity (and inflation) with QE is tantamount to pushing on a string.
I also said many times that without robust expansionary fiscal policy, recovery will at best be modest.
Two very recent ECB surveys provide strong evidence in favour of the liquidity trap narrative. The first is the latest (April 2016) Eurozone Bank Lending Survey. Here is a quote from the press release:
The net easing of banks’ overall terms and conditions on new loans continued for loans to enterprises and intensified for housing loans and consumer credit, mainly driven by a further narrowing of loan margins.
So, nothing surprising here. QE and negative rates are making so expensive for financial institutions to hold liquidity, that credit conditions keep easing.
So why do we not see economic activity and inflation pick up? The answer is on the other side of the market, credit demand. And the Survey on the Access to Finance of Enterprises in the euro area, published this week also by the ECB, provides a clear and loud answer (from p. 10):
“Finding customers” was the dominant concern for euro area SMEs in this survey period, with 27% of euro area SMEs mentioning this as their main problem, up from 25% in the previous survey round. “Access to finance” was considered the least important concern (10%, down from 11%), after “Regulation”, “Competition” and “Cost of production” (all 14%) and “Availability of skilled labour” (17%). Among SMEs, access to finance was a more important problem for micro enterprises (12%). For large enterprises, “Finding customers” (28%) was reported as the dominant concern, followed by “Availability of skilled labour” (18%) and “Competition” (17%). “Access to finance” was mentioned less frequently as an important problem for large firms (7%, unchanged from the previous round)
No need to comment, right?
Just a final and quick remark, that in my opinion deserves to be developed further: finding skilled labour seems to become harder in European countries. What if these were the first signs of a deterioration of our stock of “human capital” (horrible expression), after eight years of crisis that have reduced training, skill building, etc.?
When sooner or later the crisis will really be over, it will be worth keeping an eye on “Availability of skilled labour” for quite some time.
Tell me again that story about structural reforms enhancing potential growth?
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.
Stronger than expected GDP growth in France and Spain (0.5% and 0.8% in 2016Q1, 0.1% more than expected!) has boosted Eurozone GDP to a staggering +0.6% in the first quarter of 2016. The Financial Times notes that GDP is now above its pre-crisis level. I expect, in the next few days, celebrations in some quarters.
So, just a reminder:
The figure speaks for itself. While we had a lost decade (eight-ade), The US and the OECD as a whole were out of the woods in 2011Q2. Our neighbours across the Channel in 2013Q2. Furthermore, we were the only ones to go through a double dip recession, and are the only ones still fighting with deflationary pressures.
Of course, if we look at per capita GDP (warning, I constructed it myself, simply dividing real GDP by population on January 1st), the lost decade may materialize after all:
I added Greece as a second reminder. The country is back at case one, in yet another round of difficult negotiations. And I do believe that remembering what they have endured may help
So, tell me again, what should we be celebrating?
