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):


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.

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:

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%.

Sand Fiscal Foundations

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.

Just consider what the Commission itself states in the page dedicated to its own methodology for measuring potential output. (Their most recent methodological paper can be found here).

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.
