Spain is today the new model, together with Germany of course, for policy makers in Italy and France. A strange model indeed, but this is not my point here. The conventional wisdom, as usual, almost impossible to eradicate, states that Spain is growing because it implemented serious structural reforms that reduced labour costs and increased competitiveness. A few laggards (in particular Italy and France) stubbornly refuse to do the same, thus hampering recovery across the eurozone. The argument is usually supported by a figure like this
And in fact, it is evident from the figure that all peripheral countries diverged from the benchmark, Germany, and that since 2008-09 all of them but France and Italy have cut their labour costs significantly. Was it costly? Yes. Could convergence have made easier by higher inflation and wage growth in Germany, avoiding deflationary policies in the periphery? Once again, yes. It remains true, claims the conventional wisdom, that all countries in crisis have undergone a painful and necessary adjustment. Italy and France should therefore also be brave and join the herd.
Think again. What if we zoom out, and we add a few lines to the figure? From the same dataset (OECD. Productivity and ULC By Main Economic Activity) we obtain this:
It is unreadable, I know. And I did it on purpose. The PIIGS lines (and France) are now indistinguishable from other OECD countries, including the US. In fact the only line that is clearly visible is the dotted one, Germany, that stands as the exception. Actually no, it was beaten by deflation-struck Japan. As I am a nice guy, here is a more readable figure:
The figure shows the difference between change in labour costs in a given country, and the change in Germany (from 1999 to 2007). labour costs in OECD economies increased 14% more than in Germany. In the US, they increased 19% more, like in France, and slightly better than in virtuous Netherlands or Finland. Not only Japan (hardly a model) is the only country doing “better” than Germany. But second best performers (Israel, Austria and Estonia) had labour costs increase 7-8% more than in Germany.
Thus, the comparison with Germany is misleading. You should never compare yourself with an outlier! If we compare European peripheral countries with the OECD average, we obtain the following (for 2007 and 2012, the latest available year in OECD.Stat)
If we take the OECD average as a benchmark, Ireland and Spain were outliers in 2007, as much as Germany; And while since then they reverted to the mean, Germany walked even farther away. It is interesting to notice that unreformable France, the sick man of Europe, had its labour costs increase slightly less than OECD average.
Of course, most of the countries I considered when zooming out have floating exchange rates, so that they can compensate the change in relative labour costs through exchange rate variation. This is not an option for EMU countries. But this means that it is even more important that the one country creating the imbalances, the outlier, puts its house in order. If only Germany had followed the European average, it would have labour costs 20% higher than their current level. There is no need to say how much easier would adjustment have been, for crisis countries. Instead, Germany managed to impose its model to the rest of the continent, dragging the eurozone on the brink of deflation.
What is enraging is that it needed not be that way.
Last week’s publication of a Lancet article1 on the effect of austerity on Greek public health made a lot of noise (for those who know Italian, I suggest reading the excellent Barbara Spinelli, in La Repubblica).
The Lancet article sets the tone since the abstract, talking of “mounting evidence of a Greek public health tragedy”. It is indeed a tragedy, that highlights how fast social advances may be reversed, even in an advanced economy.
Some time ago (March 2012) I had titled a post “Greek Tragedies“. Mostly for my students, I had collected data on Greek macroeconomic variables. I concluded that austerity was self-defeating, and that at the same time it was imposing extreme hardship on Greek citizens. Of course one needed not be a good economist to know what was going on. It was enough not to work at the Commission or in Germany… But the Lancet article also allows to substantiate another claim I made at the time, i.e. that austerity would also have enormous impact in the long run. It is weird to quote myself, but here is my conclusion at the time:
Even more important, investment (pink line) was cut in half since 2007. This means that Greece is not only going through depressed growth today. But it is doing it in such a way that growth will not resume for years, as its productive capacity is being seriously dented.
What makes it sad, besides scary, is that behind these curves there are people’s lives. And that all this needed not to happen.
I think it is time for an update of the figure on the Greek tragedy. And here it is:
I said in 2012 that investment cut in half spelled future tragedy. Two years later it is down 14 more points, to 36% of 2007 levels. I am unsure the meaning of this is clear to everybody in Brussels and Berlin: when sooner or later growth will resume, the Greek will look at their productive capacity, to discover it melted. They will be unable to produce, even at the modest pre-crisis levels,without running into supply constraints and bottlenecks. I am ready to bet that at that time some very prestigious economist from Brussels will call for structural reforms to “free the Greek economy”. By the way, seven years into the crisis, the OECD keeps forecasting negative growth together with unsustainable (and growing) debt.
I also added unemployment to my personal “Greek Tragedy Watch”: Terrifying absolute numbers (almost 30% unemployment overall, youth unemployment around 60%, more than that for women!). And absolutely no trend reversal in sight. A final consideration, related to the melting of the capital stock. How much of this enormously high unemployment, is evolving into structural? How many of the unemployed will the economy be able to reabsorb, once it starts growing again? Not many, I am afraid, as there is no capital left.
Not bad as an assessment of austerity… And yet, just this morning the German government complained for a very limited softening of austerity demands. Errare umanum est, perseverare autem diabolicum…

My (very short) take on this: I do believe that Krugman has a point, a very good one, when claiming that standard textbook analysis is (almost) all you need to understand the current crisis, and to implement the correct policy solutions.
The point is what we define as “textbook analysis”. Krugman refers to IS-LM models. But these, that starting in the 1980s virtually disappeared from graduate curricula because supposedly too simplistic, not grounded on optimization, not intertemporal, and so on and so forth.
I personally was exposed to these ideas in my undergraduate studies in Italy, and I still teach them (besides using them to discuss the crisis with my students). But they were nowhere to be found during my graduate studies at Columbia (certainly not a freshwater school). None of the macro I studied in graduate school (Real Business Cycle models, or their fixed-price variant proposed by New Keynesians) as interesting as it was intellectually, could give me insight on the crisis. I simply do not need to use it.
The IS-LM model with minor amendments (most notably properly accounting for expectations to deal among other things with liquidity traps) remains a powerful tool to understand current phenomena. The problem is that it is not mainstream at all. What bothers me in Krugman’s post is the word “standard”, not “textbook analysis”.
I just published an editorial on the Italian daily il Corriere Della Sera (in Italian), that summarizes my views on the causes of the crisis and of global imbalances. It is a reprise of one of my first posts, written with Jean-Paul Fitoussi. It is useful to summarize and refresh the argument:
