A Plea for Semi-Permanent Government Deficits

December 9, 2016 2 comments

I have recently written a text on EMU governance and the implementation of a Golden Rule of public finances. I will provide the link as soon as it comes out. The last section of that paper can be read stand alone (with some editing). A bit long, I warn you, but here it is:

Because of its depth, and of its length, the crisis has triggered an interesting discussion among economists about whether the advanced economies will eventually return to the growth rates they experienced in the second half of the twentieth century.
One view, put forward by Robert Gordon  focuses on supply-side factors. Gordon argues that each successive technological revolution has lower potential impact, and that in this particular moment, “Slower growth in potential output from the supply side, emanating not just from slow productivity growth but from slower population growth and declining labor-force participation, reduces the need for capital formation, and this in turn subtracts from aggregate demand and reinforces the decline in productivity growth.

In a famous speech at the IMF in 2013, later developed in a number of other contributions, Larry Summers revived a term from the 1930s, “secular stagnation”, to describe a dilemma facing advanced economies. Summers develops some of Gordon’s arguments to argue that lower technical progress, slower population growth, the drifting of firms away from debt-financed investment, all contributed to shifting the investment schedule to the left. At the same time, the debt hangover, accumulation of reserves (public and private) induced by financial instability, increasing income inequality (on that, I came first!), tend to push the savings schedule to the right. The resulting natural interest rate is close to zero if not outright negative, thus leading to a structural excess of savings over investment.

Summers argues that most of the factors exerting a downward pressure on the natural interest rate are not cyclical but structural, so that the current situation of excess savings is bound to persist in the medium-to-long run, and the natural interest rate may remain negative even after the current cyclical downturn. The conclusion is not particularly reassuring, as policy makers in the next several years will have to navigate between the Scylla of accepting permanent excess savings and low growth (insufficient to dent unemployment), and the and Charybdis of trying to fight secular stagnation by fuelling bubbles that eliminate excess savings, at the price of increased instability and risks of violent financial crises like the one we recently experienced.

The former IMF chief economist Olivier Blanchard has elaborated on the meaning of Summers’ conjecture for macroeconomic policy. If interest rates will remain at (or close to) zero even once the crisis will be over, monetary policy will continuously face the Scylla and Charybdis. The recent crisis is a good case study of this dilemma, with the two major central banks of the world under fire from some quarters, for opposiite reasons: the Fed for having kept interest rates too low, contributing to the housing bubble  and the ECB for having done too little and too late during the Eurozone crisis.

Drifting away from the Consensus that he contributed to consolidate, Blanchard concludes that exclusive reliance on monetary policy for macroeconomic stabilization should be reassessed. With low interest rates that make debt sustainability a non-issue; with financial markets deregulation that risks yielding more variance in GDP and economic activity; and with monetary policy (almost) constantly at the Zero Lower Bound, fiscal policy should regain a prominent role among the instruments for macroeconomic regulation, beyond the cycle. This is a very important methodological advance.

Nevertheless, in his plea for fiscal policy, Blanchard falls short of a conclusion that naturally stems from his own reading of secular stagnation: If the economy is bound to remain stuck in a semi-permanent situation of excessive savings, and if monetary policy is incapable of reabsorbing the imbalance, then a new role for fiscal policy may appear, that goes beyond the short-term stabilization that Blanchard (and Summers) envision. In fact, there are two ways to avoid that the ex ante excess savings results in a depressed economy: either one runs semi-permanent negative external savings (i.e. a current account surplus), or one runs semi-permanent government negative savings. The first option, the export-led growth model that Germany is succeeding to generalize at the EMU level, is not viable, except for an individual country implementing non cooperative strategies, because aggregate current account balances need to be zero. The second option, a semi-permanent government deficit, needs to be further investigated, especially in its implication for EMU macroeconomic governance

There are a number of ways, not necessarily politically feasible, to allow EMU countries to run semi-permanent government deficits. A first one could be to restore complete national budget sovereignty, (scrapping the Stability Pact). This would mean relying on market discipline alone for maintaining fiscal responsibility. As an alternative, at the opposite side of the spectrum, countries could create a federal expenditure capacity (which would imply the creation of an EMU finance minister with capacity to spend, the issuance of Eurobonds, etc.). Such an option is as unrealistic as the previous one. In an ideal world, the crisis and deflation would be dealt with by means of a vast European investment program, financed by the European budget and through Eurobonds. Infrastructures, green growth, the digital economy, are just some of the areas for which the optimal scale of investment is European, and for which a long-term coordinated plan would necessary. The increasing mistrust among European countries exhausted by the crisis, and the fierce opposition of Germany and other northern countries to any hypothesis of debt mutualisation, make this strategy virtually impossible. The solution must therefore be found at national level, without giving up European-wide coordination, which would guarantee effective and fiscally sustainable investment programs.

In general, the multiplier associated with public investment is larger than the overall expenditure multiplier. This is particularly true in times of crisis, when the economy is, like today, at the zero lower bound. With Kemal Dervis I proposed that the EMU adopts a fiscal rule similar to the one implemented in the UK by Chancellor of the Exchequer Gordon Brown in the 1990s, and applied until 2009. The new rule would require countries to balance their current budget, while financing public capital accumulation with debt. Investment expenditure, in other words, would be excluded from deficit calculation, a principle that timidly emerges also in the Juncker plan. Such a rule would stabilize the ratio of debt to GDP, it would focus efforts of public consolidation on less productive items of public spending, and would ensure intergenerational equity (future generations would be called to partially finance the stock of public capital bequeathed to them). Last, but not least, especially in the current situation, putting in place such a rule would not require treaty changes, and it is already discussed, albeit timidly, in EU policy circles.

To avoid the bias towards capital expenditure that the golden rule could trigger, we proposed that at regular intervals, for example in connection with the European budget negotiation, the Commission, the Council and the Parliament could find an agreement on the future priorities of the Union, and make a list of areas or expenditure items exempted from deficit calculation for the subsequent years.

What Went Wrong with Jean-Baptiste

December 2, 2016 1 comment

The news of the day is that François Hollande will not seek reelection in May 2017. This is rather big news, even it if was all too logical given his approval ratings. But what went wrong with Hollande’s (almost) five years as a President?

Well, I believe that the answer is in a post I wrote back in 2014, Jean-Baptiste Hollande. There I wrote that the sharp turn towards supply side measures (coupled with austerity) to boost growth was doomed to failure, and that firms themselves showed, survey after survey, that the obstacles they faced  came from insufficient demand and not from the renown French “rigidities” or from the tax burden. I was not alone, of course in calling this a huge mistake. Many others made the same point. Boosting supply during an aggregate demand crisis is useless, it is as simple as that. Allow me to quote the end of my post:

Does this mean that all is well in France? Of course not. The burden on French firms, and in particular the tax wedge, is a problem for their competitiveness. Finding ways to reduce it, in principle is a good thing. The problem is the sequencing and the priorities. French firms seem to agree with me that the top priority today is to restart demand, and that doing this “will create its own supply”. Otherwise, more competitive French firms in a context of stagnating aggregate demand will only be able to export. An adoption of the German model ten years late. I already said a few times that sequencing in reforms is almost as important as the type of reforms implemented.

I am sure Hollande could do better than this…

It turns out that we were right. A Policy Brief (in French) published by OFCE last September puts all the numbers together (look at table 1): Hollande did implement what he promised, and gave French firms around €20bn (around 1% of French GDP) in tax breaks. These were compensated, more than compensated actually, by the increase of the tax  burden on households (€35bn). And as this tax increase assorted of reshuffling was not accompanied by government expenditure, it logically led to a decrease of the deficit (still too slow according to the Commission; ça va sans dire!). But, my colleagues show, this also led to a shortfall of demand and of growth. A rather important one. They estimate the negative impact of public finances on growth to be almost a point of GDP per year since 2012.

Is this really surprising? Supply side measures accompanied by demand compression, in a context of already insufficient demand, led to sluggish growth and stagnating employment (it is the short side of the market baby!). And to a 4% approval rate for Jean-Baptiste Hollande.

OFCE happens to have published, just yesterday, a report on public investment in which we of join the herd of those pleading for increased public investment in Europe, and in particular in France. Among other things, we estimate that a public investment push of 1% of GDP, would have a positive impact on French growth and would create around 200,000 jobs (it is long and it is in French, so let me help you: go look at page 72).  Had it been done in 2014 (or earlier) instead of putting the scarce resources available in tax reductions, things would be very different today, and probably M. Hollande yesterday would have announced his bid for a second mandate.

In a sentence we don’t need to look too far, to understand what went wrong.

Two more remarks: first, we have now mounting evidence of what we could already expect in 2009 based on common sense. Potential growth is not independent of current economic conditions. Past and current failure to aggressively tackle the shortage of demand that has been plaguing the French – and European – economy, hampers its capacity to grow in the long run. The mismanagement of the crisis is condemning us to a state of semi-permanent sluggish growth, that will keep breeding demagogues of all sorts. The European elites do not seem to have fully grasped the danger.

Second, France is not the only large eurozone country that has taken the path of supply side measures to pull the economy out of a demand-driven slump. The failure of the Italian Jobs Act in restarting employment growth and investment can be traced to the very same bad diagnosis that led to Hollande’s failure. Hollande will be gone. Are those who stay, and those who will follow, going to change course?

John Maynard Trump?

November 10, 2016 3 comments

A sentence from Donald Trump’s victory speech retained a good deal of attention:

We are going to fix our inner cities and rebuild our highways, bridges, tunnels, airports, schools, hospitals. We’re going to rebuild our infrastructure, which will become, by the way, second to none. And we will put millions of our people to work as we rebuild it.

This was widely quoted in the social media, together with the following from an FT article about the Fed:

In particular, some members of his economic advisory team are convinced that central banks such as the US Federal Reserve have exhausted their use of super-loose monetary policy. Instead, in the coming months they hope to announce a wave of measures such as infrastructure spending, tax reform and deregulation to boost growth — and combat years of economic stagnation.

In spite of its vagueness, the idea of an infrastructure push has sent markets to beyond the roof. In short, a simple (and rather generic) speech on election night has dispelled all the anxiety about the long phase of uncertainty that we face. So long for efficient markets…

But this is not what I care about here. The point I want to make is that Trump’s announcement has triggered a strange reaction. Something going like: “See? Trump managed to break the establishment’s hostility to Keynes and to finally implement the stimulus policies we need. Forget the sexism and the p-word, the attacks on minorities, the incompetence. Enter Trump, exit neo-liberalism”. I see this especially (but not only) among Italian internauts, who tend to project the European situation in other contexts.

Well, I have some reservations on this claim. Where to start? Maybe with the “Contract with the American Voter“, that together with the (generic, once more) promise of new investment, promised a massive withdrawal of the State from the economy? Or from the fact that “Establishment Obama” made Congress vote, a month into his presidency, a “Recovery Act (ARRA)” worth 7% of GDP, that successfully stopped the free-fall and helped restore growth? Or from the fact that the “anti-establishment” Tea Party forced austerity since 2011, climaxing in the sequester saga of 2013?

Critics of current austerity policies in Europe should not be delusional. Trump is not the John Maynard Keynes of 2016. His agenda is, broadly speaking, an agenda of deregulation, tax cuts for the rich, and retreat of the State from the economy. Not to mention the strong chance of a more hawkish Fed in the future. To sum up, Trump is, in the best case scenario a new Reagan, substituting military Keynesianism with bridges’ Keynesianism. And we all (should) know that Reaganomics does shine much less than usually claimed.

Those progressives looking for a Trump Keynesian agenda should probably have looked more carefully at the plan proposed by “establishment-Clinton”: A significant infrastructure push (in fact, the emphasis on infrastructures was the only point in common between the two candidates), with the ambition to crowd-in private investment. And what is more important, such an expansionary fiscal policy was framed within a more active role of the government in key sectors like education, health care, and with increased progressivity of the tax system.

Would we have had Hilary Rodham Keynes? Unfortunately we’ll never know…

A Piketty Moment

October 25, 2016 6 comments

Update (10/27): Comments rightly pointed to different deflators for the two series. I added a figure to account for this (thanks!)

Via Mark Thoma I read an interesting Atalanta Fed Comment about their wage tracker, asking whether the recent pickup of wages in the US is robust or not.

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

2016_10_26_ineq_us_1947_2016

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:

2016_10_26_ineq_us_1947_2016_update

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
1947-2016 1.51% 0.40% 0.57% 15%
1947-1970 1.62% -0.14% 0.19% 19%
1970-2016 1.42% 0.67% 0.76% 13%
1980-1992 0.64% 0.84% 0.81% 17%
1993-2000 N/A 0.68% 0.68% 0%
2001-2008Q1 4.07% 1.10% 1.41% 10%
2008Q2-2016Q2 2.17% 0.12% 0.49% 18%
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.

Monetary Policy: Credibility 2.0

October 24, 2016 3 comments

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.

Perseverare Diabolicum

July 13, 2016 1 comment

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):

2016_07_13_SpainPortugal

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.

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

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%.
